    Mysterious blobs deep inside Earth may fuel deadly volcanic eruptions - with the capability of wiping out life as we know it

    Explosive volcanic eruptions don't just damage property and cancel flights.

    They can kill hundreds or even thousands of people, burying them under lethal 'pyroclastic' flows

    Now, scientists in Australia have identified a possible cause of gigantic volcanic eruptions – mysterious 'blobs' about 1,200 miles under our feet. 

    Blobs are three-dimensional regions that span the length of continents and stretch 100 times higher than Mount Everest. 

    They sit at the bottom of Earth’s rocky mantle above the molten outer core – a place so deep that Earth’s elements are squeezed beyond recognition. 

    And they're a starting point for plumes of hot molten rock which flow upwards towards the Earth's surface. 

    There they erupt as lava, gases and rock fragments – with the capability of wiping out life as we know it. 

    The authors warn that giant, large-scale eruptions can have serious impacts, such as sudden climate change and mass extinction events.

    Earth is made up of three layers - the crust, the mantle and the core, which was later separated into 'inner' and 'outer'. A recent study suggested the existence of an 'innermost core' too

    Earth is made up of three layers - the crust, the mantle and the core, which was later separated into 'inner' and 'outer'. A recent study suggested the existence of an 'innermost core' too 

    Volcanic eruptions can intensify global warming by adding greenhouse gases such as carbon dioxide (CO2) to the atmosphere. 

    Giant volcanoes also triggered events that led to the largest mass dying on Earth, the Permian-Triassic extinction 252 million years ago. 

    'These blobs have possibly existed for hundreds of millions of years,' say the researchers from the University of Wollongong near Sydney. 

    Earth is made up of three layers – the crust, the mantle and the core, which was recently separated into 'inner' and 'outer'.

    According to the team, blobs are at the bottom of Earth’s mantle, about 1,200 miles and 1,800 miles (2,000km and 3,000km) below our feet.

    The mantle, the planet's thickest layer, is predominantly a solid rock – but blobs may be different compared with the surrounding mantle rocks. 

    Blobs are made of rock just like the rest of the mantle, but they're thought to be hotter and heavier. 

    For their study, the team used computer modeling to simulate 'mantle convection' – the movement of material in Earth's mantle powered by heat – over one billion years.

    How do scientists know about Earth's interior?

    No one can see inside the Earth, nor can drill deep enough to take rock samples from the mantle, the layer between Earth's core and crust. 

    So geophysicists use indirect methods to see what's going on deep beneath our feet.

    For example, they use seismograms, or earthquake recordings, to determine the speed at which earthquake waves propagate.

    They then use this information to calculate the internal structure of the Earth - similar to how doctors use ultrasound to see inside the body.

    Their findings suggest that mantle plumes – columns of hot molten rock in the mantle – rise up from the continent-sized blobs. 

    Mantle plumes are shaped a bit like a lollipop sticking upwards – with the 'stick' the plume tail and the 'candy' nearer Earth's surface the plume head. 

    The researchers found that locations of volcanic eruption fall either onto (or close to) the location of blobs, as predicted by their models. 

    This suggests that blobs – an acronym standing for Big LOwer-mantle Basal Structures – are essentially the deep-Earth origin of volcanic eruptions. 

    Typically, deep Earth motions are in the order of 0.4-inch (1 cm) per year, so they only become significant over tens of millions of years. 

    Blobs probably shift in a year at roughly the rate at which human hair grows each month, the team say. 

    Although they have possibly existed for hundreds of millions of years, it's unclear what causes their movement. 

    Mantle plumes rise very slowly from blobs through the mantle because they transport hot solid rock, not melt or lava. 

    Cotopaxi, one of the highest active volcano in the world, stands at 19,347 feet (5,897 metres). Historically, its activity started in 1534 when the Spanish conquistadors began to venture into the territories that are now Ecuador

    At lower pressures in the uppermost 125 miles (200 km) of Earth’s mantle, the solid rock melts, leading to volcanic eruptions.

    'We used statistics to show that the locations of past giant volcanic eruptions are significantly related to the mantle plumes predicted by our models,' explain the authors in a piece for The Conversation

    'This is encouraging, as it suggests that the simulations predict mantle plumes in places and at times generally consistent with the geologic record.' 

    The new findings, published in Communications Earth and Environment, suggest that the deep Earth is even more dynamic than we realised. 

    Future research aims to explore the chemical nature of blobs, which might be possible with simulations that track the evolution of their composition. 

    HOW CAN RESEARCHERS PREDICT VOLCANIC ERUPTIONS?

    According to Eric Dunham, an associate professor of Stanford University's School of Earth, energy and Environmental Sciences, 'Volcanoes are complicated and there is currently no universally applicable means of predicting eruption. In all likelihood, there never will be.'

    However, there are indicators of increased volcanic activity, which researchers can use to help predict volcanic eruptions. 

    Researchers can track indicators such as: 

    - Volcanic infrasound: When the lava lake rises up in the crater of an open vent volcano, a sign of a potential eruption, the pitch or frequency of the sounds generated by the magma tends to increase.

    - Seismic activity: Ahead of an eruption, seismic activity in the form of small earthquakes and tremors almost always increases as magma moves through the volcano's 'plumbing system'.

    - Gas emissions: As magma nears the surface and pressure decreases, gases escape. Sulfur dioxide is one of the main components of volcanic gases, and increasing amounts of it are a sign of increasing amounts of magma near the surface of a volcano. 

    - Ground deformation: Changes to a volcano's ground surface (volcano deformation) appear as swelling, sinking, or cracking, which can be caused by magma, gas, or other fluids (usually water) moving underground or by movements in the Earth's crust due to motion along fault lines. Swelling of a volcano cans signal that magma has accumulated near the surface.

    A massive fire has broken out near the infamous Area 51, sending plumes of smoke into the sky and UFO enthusiasts into a panic.

    A livestream camera, set up on private land just outside the heavily guarded Groom Lake facility near Rachel, Nevada, captured eerie footage of smoke rising from deep within the classified base.

    The blaze was sparked by the Gothic Fire, which has grown from 8,000 acres to 35,000 since starting on July 4. It has been confirmed as a lightning-sparked wildfire

    But that has not stopped speculation from spiraling online, with conspiracy theorists claiming everything from a crashed experimental craft to a cover-up gone wrong. 

    'I'm not saying anything other than it was aliens,' Skywatch Signal, a group that monitors strange sightings, shared on X.

    Area 51 has become a cultural phenomenon thanks to decades of conspiracy theories connecting the base to UFOs, aliens and experimental aircraft testing

    While the fire is around 15 miles outside of the military base, it is currently sweeping over where above-ground nuclear testing occurred, the Nevada Test Site, which sits 65 miles northwest of Las Vegas.

    This site, now known as the Nevada National Security Site, was established for nuclear weapons testing during the Cold War, and there is still nuclear debris and contamination in the area.

    Every 200,000-300,000 years, Earth's magnetic poles do something extraordinary.

    They completely flip, meaning the North pole becomes the South, and vice-versa.

    The last full reversal took place approximately 780,000 years ago – leaving some experts to predict another flip is imminent.

    Now, researchers have created a terrifying soundscape to represent the chaos of this event. 

    Using paleomagnetic data – the record of Earth's ancient magnetic field preserved in rocks – from around the globe, scientists have constructed a model of the magnetic field before, during and after this historic reversal.

    They also created a musical piece – a 'soundscape' – to represent the haunting sounds of the flip, called the Matuyama-Brunhes reversal.

    The team, from the Helmholtz Centre for Geosciences in Potsdam, Germany, used three violins and three cellos to create a 'disharmonic cacophony' that mirrors the complex dynamics of a flip.

    The clip starts off as melodic and makes for pleasant listening as it represents the poles while stable. However, it sounds more erratic and eerie as the magnetic fields begin to flux and change. 

    This part of the animation represents the magnetic field in a relatively stable stateHowever, this part represents it in a total state of flux, with the poles completely scrambled

    Earth is surrounded by a system of magnetic fields called the magnetosphere. This shields our home planet from harmful solar and cosmic particle radiation, but it can change shape in response to incoming space weather from the Sun. Pictured: an artist's impression

    Earth's magnetic field is generated by the roiling liquid metals deep beneath the crust.

    It extends from the Earth's interior into space, acting like a protective shield by diverting harmful charged particles from the Sun away from our planet.

    A flip doesn't happen overnight but takes place gradually, over centuries to thousands of years.

    If a magnetic flip were to happen again, some experts claim it could render parts of Earth 'uninhabitable' by knocking out power grids.

    Communication systems could be seriously disrupted, and compasses would point south – meaning Greenland would be in the southern hemisphere and Antarctica in the North.

    While it sounds terrifying, and would leave life on our planet exposed to higher amounts of solar radiation, it's unlikely to cause catastrophic events or mass extinctions.

    Last year, researchers also transformed readings of an epic upheaval of Earth's magnetic field that took place some 41,000 years ago.

    The Laschamp event saw our planet's magnetic North and South poles weaken, with the magnetic field tilting on its axis.

    During a pole reversal, Earth's magnetic North and South poles swap locations. While that may sound like a big deal, pole reversals are common in Earth's geologic history. Pictured: an artist's impression of Earth with its magnetosphere

    What is Earth's magnetic field?

    Earth's magnetic field is a layer of electrical charge that surrounds our planet. The field protects life on Earth because it deflects charged particles fired from the sun known as 'solar wind'.

    Without this protective layer, these particles would likely strip away the Ozone layer, our only line of defence against harmful UV radiation. 

    Scientists believe the Earth's core is responsible for creating its magnetic field. As molten iron in the Earth's outer core escapes it creates convection currents.  These currents generate electric currents which create the magnetic field.

    The soundscape was captured using data from a constellation of European Space Agency satellites.

    Researchers mapped the movement of Earth's magnetic field lines during the event and produced a stereo sound version using natural noises including wood creaking and rocks falling. 

    The noises in the video represent a time when the Earth's magnetic field was at just five per cent of its current strength.

    While the Earth's magnetic field did return to normal – over the course of around 2,000 years – its strength has decreased again by 10 per cent over the past 180 years, experts have found.

    However, a mysterious area in the South Atlantic has emerged where the geomagnetic field strength is decreasing even more rapidly.

    The area is called the South Atlantic Anomaly and has seen satellites malfunctioning over it several times due to exposure to highly charged particles from the sun.

    This has led to speculation that Earth is heading towards a magnetic pole flip.

    However, some experts have provide reassurance that the poles aren't going to flip anytime soon.

    Researchers previously pieced together data on Earth's geomagnetic field strength stretching back 9,000 years and say there's no evidence a reversal is on the cards. 

    article image

    'We have mapped changes in the Earth's magnetic field over the past 9,000 years, and anomalies like the one in the South Atlantic are probably recurring phenomena linked to corresponding variations in the strength of the Earth's magnetic field', said Andreas Nilsson, a geologist at Lund University.

    The team analysed burnt archaeological artefacts, volcanic samples and sediment drill cores – all of which carry information about Earth's magnetic field.

    Reassuringly, the team's model suggests that the South Atlantic Anomaly will recover of its own accord and is unlikely to trigger the reversal that some have anticipated.

    'Based on similarities with the recreated anomalies, we predict that the South Atlantic Anomaly will probably disappear within the next 300 years, and that Earth is not heading towards a polarity reversal', Mr Nilsson said.

    WHAT COULD HAPPEN TO EARTH IF ITS POLES FLIPPED?

    The Earth’s magnetic field is in a permanent state of change. 

    Magnetic north drifts around and every few hundred thousand years the polarity flips so a compass would point south instead of north. 

    The strength of the magnetic field also constantly changes and currently it is showing signs of significant weakening. 

    Life has existed on the Earth for billions of years, during which there have been many reversals. 

    There is no obvious correlation between animal extinctions and those reversals. Likewise, reversal patterns do not have any correlation with human development and evolution.

    It appears that some animals, such as whales and some birds use Earth's magnetic field for migration and direction finding.

    Since geomagnetic reversal takes a number of thousands of years, they could well adapt to the changing magnetic environment or develop different methods of navigation.

    Radiation at ground level would increase, however, with some estimates suggesting that overall exposure to cosmic radiation would double causing more deaths from cancer. ‘But only slightly,’ said Professor Richard Holme.

    ‘And much less than lying on the beach in Florida for a day. So if it happened, the protection method would probably be to wear a big floppy hat.’

    The movement of the Earth's magnetic poles are shown in this animation at 10-year intervals from 1970 to 2020.

    Electric grid collapse from severe solar storms is a major risk. As the magnetic field continues to weaken, scientists are highlighting the importance off-the grid energy systems using renewable energy sources to protect the Earth against a black out. 

    'The very highly charged particles can have a deleterious effect on the satellites and astronauts,' added Dr Mona Kessel, a Magnetosphere discipline scientist at Nasa.

    In one area, there is evidence that a flip is already occurring. ‘The increasing strength of the South Atlantic anomaly, an area of weak field over Brazil, is already a problem,’ said Professor Richard Holme. 

    The Earth's climate could also change. A recent Danish study has found that the earth's weather has been significantly affected by the planet's magnetic field.

    They claimed that fluctuations in the number of cosmic rays hitting the atmosphere directly alter the amount of cloud covering the planet.

    Henrik Svensmark, a weather scientist at the Danish National Space Centre who led the team behind the research, believes that the planet is experiencing a natural period of low cloud cover due to fewer cosmic rays entering the atmosphere.

    Mysterious new world has just been discovered in our solar system

    Astronomers have discovered a new world circling the outer edges of our solar system.

    Researchers using the Subaru Telescope, located in Hawaii, spotted a small, distant object called 2023 KQ14 far beyond Pluto. They've given it the nickname Ammonite.

    2023 KQ14 is a rare type of object called a 'sednoid,' a small, icy body in the outer solar system, similar to the icy rocks floating in the Kuiper Belt or dwarf planets like Pluto.

    So far, there are only four known objects like it in our solar system. 2023 KQ14 is about 71 times farther from the sun than Earth is.

    This object follows a unique, stretched-out orbit that has stayed stable for about 4.5 billion years.

    Scientists found that 2023 KQ14's orbit was similar to the other sednoids in the solar system for billions of years, but that has mysteriously changed over time, suggesting the outer solar system is a more complex space than we thought.

    This discovery also makes the possible existence of 'Planet Nine' less likely, as 2023 KQ14's orbit doesn't quite fit with where scientists believe that world would be.

    Dr Yukun Huang from the National Astronomical Observatory of Japan said: 'It is possible that a planet once existed in the solar system but was later ejected, causing the unusual orbits we see today.'

    Planetary scientist Fumi Yoshida added that Ammonite was found in a region of space far beyond the influence of Neptune's gravity

    'The presence of objects with elongated orbits and large perihelion distances in this area implies that something extraordinary occurred during the ancient era when 2023 KQ14 formed,' Yoshida explained in a statement.

    Scientists are calling Ammonite a cosmic 'fossil' from the beginnings of the solar system.

    The discovery was part of the Formation of the Outer Solar System: An Icy Legacy (FOSSIL) survey project.

    The project's name itself reflected the goal of finding objects like Ammonite that act as 'icy fossils,' preserving information about the outer solar system's formation and evolution.

    'I would be happy if the FOSSIL team could make many more discoveries like this one and help draw a complete picture of the history of the solar system,' Yoshida said.

    Until now, astronomers had been focused on proving the existence of the fabled Planet Nine (or Planet X as NASA calls it), a mysterious ninth planet believed to be hiding far beyond Pluto at the edge of the solar system.

    A recent study had whittled a list of 13 candidates down to just one potential object slowly moving around our sun approximately 46.5 billion to 65.1 billion miles away.

    To put that in perspective, that hypothetical planet would be almost 20 times farther away from the sun than Pluto is.

    However, the Japanese team’s discovery of Ammonite (2023 KQ14) challenges the Planet Nine theory, as its unique orbit suggests that Planet Nine, if it exists, would need to be even farther from the sun than previously thought.

    This has led the researchers who discovered Ammonite to hypothesize that a mystery planet (possibly Planet Nine) was somehow thrown out of its orbit around the sun long ago.

    article image

    Scientists had been using the Planet Nine theory to explain some of the unsolved mysteries still surrounding our tiny corner of the Milky Way galaxy.

    In a breakdown of Planet Nine, NASA said: 'It could also make our solar system seem a little more 'normal.'

    'Surveys of planets around other stars in our galaxy have found the most common types to be 'super Earths' and their cousins — bigger than Earth, but smaller than Neptune,' NASA researchers continued.

    'Yet none of this kind exist in our solar system. Planet Nine would help fill that gap.'

    If astronomers had found a giant planet at the rim of the solar system, it could explain why objects in the Kuiper Belt are tilted by about 20 degrees with respect to the plane the planets sit on as they orbit the sun.

    Planet Nine's gravity would be pulling on these objects over long periods of time, tilting their orbits so the entire ice belt would be out of line with the planets.

    The existence of Planet Nine and its strong gravity would also explain why all these comets and tiny dwarf planets like Pluto all cluster together and move in the same direction without floating away.

    Is Yellowstone's supervolcano on the brink of erupting? Scientists discover a new HOLE in one of the park's basins

    Scientists have just discovered a new hole in a basin in Yellowstone National Park - raising fears the supervolcano could be on the brink of erupting.  

    The unsettling 13-foot gap is located at Norris Geyser Basin – one of the hottest, oldest and most dynamic of Yellowstone's thermal areas. 

    Experts at the United States Geological Survey (USGS) say it formed over several months, starting at around Christmas 2024. 

    Despite being a channel of bubbling volcanic activity, a photo from the government agency shows the cavity as a serene pool. 

    With its unusually light blue water and brilliant white sand, the scene looks like it was captured on a faraway planet. 

    The discovery comes just four months after the USCS discovered a newly opened volcanic vent in Yellowstone, spewing steam into the air.

    Yellowstone is one of the world's largest active volcanoes - and if it erupted, it would cover up to two-thirds of the US with ash.

    Entire states could become uninhabitable as toxic air sweeps through it, grounding thousands of flights and forcing millions to leave their homes. 

    The new thermal pool at Yellowstone National Park (pictured) likely formed in a series of mildly explosive events between late December 2024 and early February 2025. The rocks and white material (silica mud) surrounding the pool were probably ejected as the feature formed

    The new thermal feature, discovered by geologists on April 10 but only revealed this week, is a 'blue water spring' – a natural exit point producing exceptionally pure, clear water. 

    The water is relatively warm (about 43°C/109°F), light blue in colour and reaches about one foot (30cm) below the rim of the pool. 

    In terms of the cause of its creation, the experts point to a 'hydrothermal explosion' – an eruption of such force that boiling water, mud and surrounding rocks are broken and flung through the air.

    Satellite imagery suggests it happened as a series of mildly explosive events between late December 2024 and early February 2025 prior to discovery. 

    The imagery shows there was no feature present in the spot on December 19, but by January 6, a small depression had formed there.

    Another image from February 13 shows the fully formed water pool, overall indicating that it did not form in a single major explosive event. 

    Rocks and pure white geothermal mud made of silica surrounding the pool were probably ejected during 'multiple small events'. 

    In contrast, other hydrothermal features at Yellowstone have formed during 'brief and violent episodes of change'. 

    This satellite imagery dated February 15 shows the new fully-formed thermal pool at Norris Geyser Basin, Yellowstone National Park. There is no indication of the pool in images from October 19 and December 19, 2024, but a small depression is visible in a January 6 image

    What is Yellowstone? 

    One of the most famous volcanos on Earth, Yellowstone is located beneath a national park spanning three states - Idaho, Wyoming and Montana. 

    There lies a magma chamber, pulsing with molten and superheated rock and toxic gases such as sulfur dioxide (SO2) and hydrogen sulfide (H2S). 

    Old Faithful, Yellowstone National Park's famous geyser, which has erupted jets of boiling water every 44 to 125 minutes into the air continuously for the last 800 years.

    Erupting an average of 130 feet into the air at 200°F the thermal attraction could prove fatal to anyone in close proximity when it blows.

    When we think of volcanoes we tend to think of striking cone-shaped features that rise high into the sky, but Yellowstone volcano is largely underground. 

    Yellowstone volcano blew catastrophically 630,000 years ago and many fear it's getting ready for another eruption, but fortunately, the new hole doesn't necessarily indicate it is in any immediate danger of doing so. 

    Dr Craig Magee, geologist at the University of Leeds, stressed that Yellowstone has a 'long history of hydrothermal activity'. 

    'There are lots of small earthquakes and subtle changes in ground elevation regularly recorded there,' he told MailOnline. 

    'All these tell-tale signs, and others, indicate Yellowstone has an active magmatic and hydrothermal system beneath it.

    'But the occurrence of one event, like this single hydrothermal explosion, is unlikely to represent increasing volcanic activity or a move closer to eruption; it is just a symptom.' 

    According to the academic, if Yellowstone had 'swarms' of hydrothermal explosions, plus increasing seismic activity and ground movement, it could suggest increased activity level. 

    However, volcanoes do not work in predictable ways and their eruptions do not follow predictable patterns or schedules.

    Hydrothermal explosions are caused by pressure changes that result from the transition of liquid water to steam, but even scientists know 'relatively little' about them, according to Dr Magee.

    'In Yellowstone, hydrothermal explosions are one of the main hazards the numerous tourists who visit may come across,' he told MailOnline. 

    The unusually light blue water in this one 'could be very salty or even acidic', so visitors wouldn't want to fall in, he added.

    Despite its potency, Yellowstone National Park's famous volcanic activity draws about 4 million tourists per year from around the world.

    One of the park's most famous geothermal features, the Old Faithful geyser, spews jets of boiling water every 44-125 minutes. 

    According to a recent study, Yellowstone's magma chamber is just 2.3 miles (3.8km) or about 12,500 feet below Earth's surface. 

    This marginal distance is about the same as between Buckingham Palace and St Paul's Cathedral in London, but the study authors also did not consider an eruption to be imminent. 

    COULD AN ERUPTION AT THE YELLOWSTONE SUPERVOLCANO BE PREVENTED?

    Previous research found a relatively small magma chamber, known as the upper-crustal magma reservoir, beneath the surface

    Nasa believes drilling up to six miles (10km) down into the supervolcano beneath Yellowstone National Park to pump in water at high pressure could cool it.

    Despite the fact that the mission would cost $3.46 billion (£2.63 billion), Nasa considers it 'the most viable solution.' 

    Using the heat as a resource also poses an opportunity to pay for plan - it could be used to create a geothermal plant, which generates electric power at extremely competitive prices of around $0.10 (£0.08) per kWh.

    But this method of subduing a supervolcano has the potential to backfire and trigger the supervolcanic eruption Nasa is trying to prevent.

    'Drilling into the top of the magma chamber 'would be very risky;' however, carefully drilling from the lower sides could work. 

    This USGS graphic shows how a 'super eruption' of the molten lava under Yellowstone National Park would spread ash across the United States

    Even besides the potential devastating risks, the plan to cool Yellowstone with drilling is not simple.

    Doing so would be an excruciatingly slow process that one happen at the rate of one metre a year, meaning it would take tens of thousands of years to cool it completely. 

    And still, there wouldn't be a guarantee it would be successful for at least hundreds or possibly thousands of years.

    A massive explosion of solar plasma erupted from the sun on Wednesday, and scientists say this may be just the beginning. 

    NASA satellites caught the dramatic moment when a blazing arc of superheated material burst from the Sun's northeastern edge, large enough to stretch across 30 Earths.  

    The violent blast carved out a 250,000-mile-long 'canyon of fire', with walls of glowing plasma rising more than 12,000 miles high, roughly the height of Earth's diameter.

    The eruption was caused by a solar filament, a thick ribbon of solar material, which snapped and collapsed, firing off a giant cloud of particles known as a coronal mass ejection (CME).

    While this CME isn't expected to hit Earth, experts are warning that the sun is becoming more active, and future eruptions could strike our planet head-on.

    If one does, it could unleash a geomagnetic storm, a powerful solar disturbance that has the potential to knock out power grids, satellites, and GPS systems.

    The warning comes as solar activity ramps up during its current cycle, increasing the risk of Earth being caught in the path of a direct hit.

    It was triggered by a solar filament, a dense, rope-like ribbon of solar material, that suddenly snapped and collapsed and shoot a coronal mass ejection (CME)

    NASA satellites captured the colossal explosion as it exploded off the sun's northeastern edge, blasting a glowing arc of superheated material enough to stretch across 30 Earths

    While astronomers feared the violent burst of energy could hit Earth, the space weather forecast shows our planet is in the clear of a geomagnetic storm.

    However, the National Oceanic and Atmospheric Administration's space weather center listed a 60 percent chance of radio blackouts today and into the weekend due to solar activity.

    NASA says the blast was so intense it twisted and tore the sun's magnetic field, leaving behind a glowing trench of charged particles where the explosion ripped through.

    Similar outbursts from the sun have already wreaked havoc, including a May solar storm that sparked auroras across the US, lighting up skies from California to Alabama and prompting warnings about possible power outages and satellite disruptions.

    The latest eruption was caused by a solar filament, a massive ribbon of dense material that floats above the sun's surface. 

    These filaments are held in place by invisible magnetic forces, but when those break down, the entire structure can collapse and explode.

    Tony Phillips, an astronomer who manages Spaceweather.com, said: 'Debris from the filament flew through the sun's atmosphere, carving a 'canyon of fire' more than 248,548 miles long. 

    'The walls of the canyon are at least 32,186 miles high--a grand canyon, indeed.'

    CMEs like this are massive clouds of solar material hurled into space when the Sun's magnetic fields shift violently

    Phillips also noted that the eruption hurled a CME into space, but at the time, astronomers feared it was on a direct path toward Earth.

    'We don't yet know if there is an Earth-directed component. Confirmation awaits additional images from [NASA's Solar and Heliospheric Observatory (SOHO)].

    SOHO is a project of international cooperation between the European Space Agency (ESA) and NASA to study the sun, from its deep core to the outer corona, and the solar wind.

    Another massive solar eruption occurred in May, but this one measured about 600,000 miles wide, making it more than twice as long as the distance from the Earth to the moon.  

    Stunning video recorded by NASA's solar observation satellites shows the moment that filaments of plasma 75 times larger than Earth peeled away from the sun in a pair of sweeping 'wings.'

    Exploding stars come in different types, and these different types of supernovae show astronomers different things about the cosmos. There's a scientific appetite to find more of them and boost our knowledge about these exotic events. The Nancy Grace Roman Space Telescope should be able to feed that appetite.

    The Roman is due to launch in about two years, and will make its way to its station at the Sun-Earth L2 orbit. After commissioning, it'll begin operations. One of its three primary surveys is the High-Latitude Time-Domain Survey. In that survey, the powerful space telescope will image the same section of sky beyond the Milky Way every five days for two years. The team behind the Roman will stitch these scenes together into one comprehensive movie, a sort of cosmic cinema.

    These movies will reveal the presence of Type 1a supernovae. These occur in binary star systems where one star is a white dwarf. White dwarfs have immense gravitational force because they're extremely dense objects. They draw material away from their companion stars, which could be anything from another white dwarf to a giant star. That material builds up on the white dwarf's surface, and when it reaches a critical mass, it triggers a runaway reaction and a supernova explosion.

    Type 1a are different from what we can call standard supernovae. Those are core-collapse supernovae, where a massive star collapses into a neutron star or a black hole, or is completely destroyed and leaves behind only a diffuse nebula.

    Since Type 1a supernovae explode at a fixed mass, their peak luminosity is known. For that reason, they serve as standard candles, tools astronomers use to accurately gauge the distance to their home galaxies. These accurate distances allow cosmologists to trace the expansion of the Universe.

    The Roman's High-Latitude Time-Domain Survey is a critical part of its mission and is aimed at finding Type 1a supernovae and other transients. According to new research and simulations, it should find about 27,000 of them, a shocking number that's about ten times greater than the current number of known Type 1a SN. This comprehensive data set should help cosmologists in their quest to map the expansion of the Universe, a critical part of understanding dark energy.

    Evidence is mounting that dark energy has changed over time, and Roman will help us understand that change by exploring cosmic history in ways other telescopes can’t.” - Dr. Ben Rose - Dept. of Physics and Astronomy, Baylor University

    The 27,000 number comes from new research published in The Astrophysical Journal titled "The Hourglass Simulation: A Catalog for the Roman High-latitude Time-domain Core Community Survey." The lead author is Dr. Ben Rose, an assistant Professor of Physics in the Department of Physics and Astronomy at Baylor University.

    The Roman will find these explosions by observing light from distant galaxies and looking back in time. The Roman will push that time boundary and allow astronomers to see Type 1a SN further back than ever. Most of the T1a SN observed so far exploded in the last 8 billion years. The Roman's High-Latitude Time-Domain Survey (HLTDS) will uncover thousands that exploded longer than 10 billion years ago, and dozens that exploded even earlier than that. These standard candles will fill a missing gap and are critical evidence of the Universe's expansion in its early age.

    This graphic outlines the Nancy Grace Roman Space Telescope's High-Latitude Time Domain Survey. The survey’s main component will cover over 18 square degrees — a region of sky as large as 90 full moons — and will detect supernovae that occurred up to about 8 billion years ago. Smaller areas within the survey can look even further back in time, potentially back to when the universe was around a billion years old. The survey will be split between the northern and southern hemispheres, located in regions of the sky that will be continuously visible to Roman. The bulk of the survey will consist of 30-hour observations every five days for two years in the middle of Roman’s five-year primary mission. Image Credit: NASA's Goddard Space Flight Center

    “Filling these data gaps could also fill in gaps in our understanding of dark energy,” lead author Rose said in a press release. “Evidence is mounting that dark energy has changed over time, and Roman will help us understand that change by exploring cosmic history in ways other telescopes can’t.”

    Every supernova is essentially a flash in the cosmos, and dissecting the light from the flash reveals what type of event released it. Core collapse SN and T1a SN aren't easy to distinguish at such great distances, but the light changes over time, and can be split apart with spectroscopy to learn more about it. The Roman carries two instruments, and one of them, the Wide-Field Instrument (WFI), allows the telescope to do large-scale spectroscopic surveys.

    “By seeing the way an object’s light changes over time and splitting it into spectra — individual colors with patterns that reveal information about the object that emitted the light—we can distinguish between all the different types of flashes Roman will see,” said Rebekah Hounsell, study co-author and assistant research scientist at the University of Maryland-Baltimore County working at NASA’s Goddard Space Flight Center.

    The Hourglass Simulation "uses the most up-to-date spectral energy distribution models and rate measurements for 10 extragalactic time-domain sources," the authors explain in their research. "We simulate these models through the design reference Roman Space Telescope survey."

    "In total, Hourglass has over 64,000 transient objects, 11,000,000 photometric observations, and 500,000 spectra," the authors write. Hourglass showed that the Roman can expect to find "approximately 21,000 Type Ia supernovae, 40,000 core-collapse supernovae, around 70 superluminous supernovae, ∼35 tidal disruption events, three kilonovae, and possibly pair-instability supernovae."

    This impressive data set will drive the study and understanding not only of dark energy, but of many other transient events too. As of 2024, for example, astronomers knew of only about 260 superluminous supernovae (SLSNe). These explosions can be 10p times as luminous as other SN. Only massive stars greater than 40 solar masses are expected to explode as SLSNe, yet astrophysicists aren't certain what causes them. Finding an additional 70 could provide answers to some outstanding questions.

    The Hourglass Simulation is designed to prepare the science community for the Roman's deluge of data. With its tens of thousands of transients, millions of photometric observations, and hundreds of thousands of spectra, Hourglass will serve as a training tool. "Additionally, Hourglass is a useful data set to train machine learning classification algorithms."

    "With the dataset we’ve created, scientists can train machine-learning algorithms to distinguish between different types of objects and sift through Roman’s downpour of data to find them,” Hounsell added in the press release. “While searching for type Ia supernovae, Roman is going to collect a lot of cosmic ‘bycatch’—other phenomena that aren’t useful to some scientists, but will be invaluable to others.”

    Among those other phenomena are Tidal Disruption Events (TDE), which occur when a black hole consumes a star. Astronomers know of about 100 of them, and they can reveal the presence of black holes that are otherwise dormant and undetectable. If the Roman can find an additional 35, that will undoubtedly help them answer some of their questions. Not only are their outstanding questions about black holes' masses and spina, but there are also questions about how stars behave in the dense regions near galactic centers.

    Kilonovae are another type of cosmic explosion and occur when two neutron stars or a neutron star and a black hole collide. Though they're fainter than SN, Kilonovae release gravitational waves and also produce substantial amounts of heavy elements like gold, platinum, and uranium. There's only one confirmed kilonova explosion, and there are many outstanding questions about them. Astrophysicists want to understand the composition of these elements in their ejecta, and how often they occur and if there are multiple types. If the Roman can find three more, that's a massive increase in the dataset scientists have to work with.

    Pair-instability supernovae are another exotic type of stellar explosion that scientists want to know more about. Only extremely massive stars between about 130 to 250 solar masses can explode as pair-instability supernovae (PISNe), and they don't leave neutron stars or black holes behind. The progenitor stars is completely destroyed, and only an expanding nebula of gas and dust, including heavy elements synthesized in the explosion, is left behind. Astrophysicists want to know the exact stellar mass of their progenitors and what role metallicity plays.

    As it stands now, astrophysicists have only a small handful of candidate PISNe, and if the Roman can find ten of them like the simulation suggests, researchers will have a lot more data to work with.

    “I think Roman will make the first confirmed detection of a pair-instability supernova,” Rose said. “They’re incredibly far away and very rare, so you need a telescope that can survey a lot of the sky at a deep exposure level in near-infrared light, and that’s Roman.”

    As NASA's next flagship astrophysics mission, the Nancy Grace Roman Space Telescope will make an enormous contribution to our understanding of different types of cosmic explosions. By stitching together its observations into movies that show how different cosmic explosions take place, it will advance our scientific knowledge considerably.

    “Whether you want to explore dark energy, dying stars, galactic powerhouses, or probably even entirely new things we’ve never seen before, this survey will be a gold mine,” said Rose.

    Each time a new telescope mission is launched, it's after years or even decades of preliminary work, including figuring out what questions need to be asked and what instruments are needed to find the answers. Simulations like the Hourglass simulation are becoming more common, as the astronomy community anticipates and prepares for new data from upcoming missions.

    But each mission also produces surprises, and though they're unpredictable, scientists often mention how excited they are to find surprising new things.

    “Roman’s going to find a whole bunch of weird and wonderful things out in space, including some we haven’t even thought of yet,” Hounsell said. “We’re definitely expecting the unexpected.”

    Sadly, the current US administration has taken aim at NASA's budget and announced that the Roman's funding will be cut. Since the current administration has gained a reputation for confusing announcements that are sometimes later rescinded, the mission's future is unclear.

    If it is approved and launched, its precious dataset will be a feast for astrophysicists around the world and will help drive a deeper understanding of Nature and some of its most extreme objects and events.

    Despite the powerful telescopes that modern astronomers have to work with, the distant reaches of the Solar System are still mysterious. Not much sunlight pierces these regions, and there are strong hints that undiscovered objects lurk there. The objects that astronomers have discovered in these dim reaches are primordial, and their orbits suggest the presence of more undiscovered objects. Piecing it all together is a challenge.

    While some objects announce themselves with fiery explosions or streaks of light across the sky, distant Solar System objects don't attract much attention. They reveal themselves in tiny hints; a nearly imperceptible tug on another object, a nearly-invisible and short-lived glimmer of light. Yet these objects have something important to tell us about how our Solar System formed and evolved.

    Astronomers have detected hints of a ninth planet in the Solar System's distant reaches. This hypothetical and elusive Planet Nine is held up to explain the puzzling orbital groupings of a family of distant objects called Trans-Neptunian Objects (TNO).

    Astronomers working with Japan's Subaru Telescope in Hawaii found evidence of a new distant object in the Solar System. It's a Trans-Neptunian Object, meaning it orbits the Sun at a greater average distance than Neptune, the outermost planet. But it's also a member of an important and puzzling sub-class of objects: Sednoids. It's name is 2023 KQ14, but its nickname is Ammonite, after the fossilized cephalopod.

    Sednoids follow more extreme orbits than TNOs. Their orbits are extremely elongated, with high eccentricity, distant perihelia, and large semi-major axes. They're named after the dwarf planet Sedna, and the new discovery is only the fourth Sednoid ever detected.

    A new paper in Nature Astronomy presented the discovery. It's titled "Discovery and dynamics of a Sedna-like object with a perihelion of 66 au." The lead author is Ying-Tung Chen from the Academia Sinica Institute of Astronomy and Astrophysics in Taipei, Taiwan.

    "Understanding the orbital evolution and physical properties of these unique, distant objects is crucial for comprehending the full history of the Solar System." - Dr. Fumi Yoshida, co-author.

    Ammonite was first detected with the Subaru Telescope during observation efforts in March, May, and August 2023. Those observations alone weren't sufficient to confirm the dim object's existence, and follow-up observations in July 2024 with the Canada-France-Hawaii Telescope, as well as a search through archived data from other observatories, provided confirmation. Overall, the researchers tracked Ammonite's orbit for 19 years.

    Ammonite was found as part of the FOSSIL (Formation of the Outer Solar System: An Icy Legacy) observing program. It uses the Subaru Telescope's powerful HyperSuprimeCam to measure the populations and sub-populations of the objects that populate the outer Solar System. The FOSSIL team used computer numerical simulations to determine that Ammonite has followed a stable orbit for at least 4.5 billion years, dating all the way back to the Solar System's earliest times. Ammonite's orbit is currently different from the other Sednoids, but the simulations show that there orbits were all similar about 4.2 billion years ago.

    There's an odd gap in distant Solar System objects when it comes to their perihelion distances and Ammonite sits in that gap. "The orbit of Ammonite does not align with those of the other Sedna-like objects and fills the previously unexplained ‘q-gap’ in the observed distribution of distant Solar System objects," the authors explain in their paper.

    This figure is divided into two panels divided by a vertical black line, and shows the orbital data for outer Solar System objects. The left side shows the semi-major axis versus perihelion distribution, with the red vertical dashed line representing the approximate region where galactic tides and passing stars can perturb the orbits of TNOs. The horizontal black lines show the upper boundary of chaotic diffusion and gravitational scattering by Neptune. The named objects all have large perihelia, and it clearly shows hos Ammonite is different from the others. It's in the region that currently lacks any other detections. The right side shows how Ammonite falls outside the proposed clustering of objects with large perihelia. Image Credit: Chen et al. 2025. NatAstr. https://doi.org/10.1038/s41550-025-02595-7

    Dr. Yukun Huang of the NAOJ is a co-author of the paper who conducted simulations of Ammonite's orbit. "The fact that 2023 KQ14’s current orbit does not align with those of the other three sednoids lowers the likelihood of the Planet Nine hypothesis," Huang said in a press release. "It is possible that a planet once existed in the Solar System but was later ejected, causing the unusual orbits we see today."

    Neptune is the only known massive object near the outer Solar System that could have shaped the orbits of the TNOs and Sednoids. But according to study co-author Dr. Fumi Yoshida, Ammonite is beyond its reach.

    “2023 KQ14 was found in a region far away where Neptune’s gravity has little influence. The presence of objects with elongated orbits and large perihelion distances in this area implies that something extraordinary occurred during the ancient era when 2023 KQ14 formed," Yoshida said. "Understanding the orbital evolution and physical properties of these unique, distant objects is crucial for comprehending the full history of the Solar System. At present, the Subaru Telescope is among the few telescopes on Earth capable of making such discoveries. I would be happy if the FOSSIL team could make many more discoveries like this one and help draw a complete picture of the history of the Solar System.”

    Ammonite's orbit is now different from the other Sednoids, and that fact needs an explanation. It's evidence that there's more complexity and diversity among distant Solar System objects. Astronomers have long wondered if our Solar System hosts a 'Planet Nine' that has shepherded the orbits of these distant objects. If there is, then Ammonite's discovery places more constraints on its orbit, and where it may be hiding. It effectively reduces the number of hiding spots for this hypothetical planet.

    "Sedna-like objects with large semi-major axes (a > 200 au) and large perihelia (q > 60 au) appear to evolve in stable orbits that have remained largely unchanged and not altered by the gravity of Neptune since the formation of the Solar System," the researchers explain in their paper. "No viable transfer mechanisms to raise their perihelia exist with the current configuration of planets. Their stability suggests that an external gravitational influence beyond those of the currently known Solar System planets is required to form their orbits."

    This figure shows the orbits of the four Sednoids, with Neptune's orbit around the Sun shown for comparison. "Ammonite’s longitude of perihelion is in the opposite direction of the other Sedna-like objects," the authors explain. "Its high perihelion suggests the potential for long-term orbital stability," and it's valuable for testing the hypothesized clustering of Sednoids and the hypothetical Planet Nine.

    Astronomers have proposed many sources for this external gravitational influence, including interactions with a rogue planet or star, ancient stellar interactions from when the Sun was still in its natal cluster, and the capture of objects from other lower-mass stars in the Solar System's early times. But the explanation that gets the most attention is interactions with a hypothetical planet, Planet Nine.

    While this study neither confirms nor disputes the existence of Planet Nine, it does place further constraints on its orbit. In fact, each time another Sednoid is discovered, it constrains Planet Nine. Astronomers now know of four of them, but they don't know how many may still be hiding out there, potentially shepherded by the elusive, hypothetical, Planet Nine.

    If Planet Nine exists, it has a huge area to hide in. Some astronomers who have studied its potential existence think it could be the fifth largest planet in the Solar System. It would be so far away that it would be extremely dim. However, we may be on the cusp of detecting it, if it exists.

    The Vera Rubin Observatory recently saw first light and will begin its decade-long Legacy Survey of Space and Time (LSST). The LSST will find transient events and objects in the Solar System like no other telescope before it. It's purpose-built to find hard to detect objects, and not even an elusive object like Planet Nine may be able to hide from it.

    Geheimen onthuld door klokkenluider Edward Snowden
    In 2013 lekte Edward Snowden, een onderaannemer van de National Security Agency (NSA), geheime documenten waarin het bestaan van uiterst geheime surveillanceprogramma's werd onthuld. Als een van de meest beruchte klokkenluiders van de afgelopen tijd stond Snowden aan de basis van het grootste beveiligingslek in de geschiedenis van het Agentschap. Zijn onthullingen onthulden talloze wereldwijde spionagetactieken, veel uitgevoerd door de NSA en het Britse Government Communications Headquarters (GCHQ). Na de sensationele onthullingen vluchtte Snowden naar Moskou. In 2022 werd hij genaturaliseerd tot Russisch staatsburger.

    De acties van Edward Snowden dwongen de Amerikaanse inlichtingendiensten om toe te geven dat ze hun eigen burgers op grote schaal bespioneerden. Het legde ook wereldwijde surveillanceoperaties bloot van zowel de NSA als de GCHQ. Maar wat is er precies gelekt en wie is erdoor getroffen?

    Where dimensions collide, rip in our reality, possibly caused by CERN. 😱 UFO UAP sighting news 👽 Wow!


    Date of discovery: July 2025
    Location of discovery: Lisbon, Portugal
    Coordinates: 38°46'0.29"N 9° 8'5.92"W
     
    At the Lisbon airport there is a single passenger jet with out wings! It has a shadow, but no wing shadow...and how is that possible? Well, Portugal is not far from CERN which causes not just mini black holes which we saw over Norway the day Obama got a Nobel Prize, but CERN also causes temporary rips in time and space into other dimensions. The wings went there, then came back. Amazing and the satellite caught it all.

    Gemini North Telescope Captures New Images of Interstellar Comet 3I/ATLAS

    Astronomers using the Gemini North telescope at NSF’s International Gemini Observatory have captured 3I/ATLAS as it makes its temporary passage through our cosmic neighborhood.

    Interstellar objects are objects that originate outside of, and are observed passing through, our Solar System.

    Ranging from tens of meters to a few kilometers in size, these objects are pieces of cosmic debris leftover from the formation of their host star’s planetary systems.

    As these remnants orbit their star, the gravity of nearby larger planets and passing nearby stars can launch them out of their home systems and into interstellar space, where they can cross paths with other solar systems.

    Interstellar visitors are valuable objects to study since they offer a tangible connection to other star systems.

    They carry information about the chemical elements that were present when and where they formed, which gives scientists insight into how planetary systems form at distant stars throughout our Milky Way Galaxy’s history — including stars that have since died out.

    3I/ATLAS is only the third interstellar object ever discovered after 1I/ʻOumuamua in 2017 and 2I/Borisov in 2019.

    While astronomers think many interstellar objects exist, and likely pass through our Solar System on a regular basis, they are exceptionally difficult to capture since they are only visible when they’re close enough to see and when our telescopes are pointing in the right place at the right time.

    Multiple teams around the globe are using a wide variety of telescopes to observe 3I/ATLAS during its temporary visit to our Solar System, allowing them to collectively determine some of the comet’s key characteristics.

    Although much remains unknown, it is already clear that 3I/ATLAS is unique compared to 1I/ʻOumuamua and 2I/Borisov.

    Observations so far suggest that 3I/ATLAS has an approximate diameter of at most 20 km (12 miles), compared to ‘Oumuamua’s diameter of 200 m and Borisov’s of less than one km.

    The new comet also has an exceptionally eccentric orbit, where eccentricity describes how much an object’s orbital pathway is ‘stretched out.’

    An eccentricity of 0 is a perfectly circular orbit, while an eccentricity of 0.999 is a very stretched-out ellipse.

    An object with an eccentricity above 1 is on a path that does not loop back around the Sun, implying it comes from — and will return to — interstellar space.

    3I/ATLAS has an eccentricity of 6.2, which is highly hyperbolic and ensures its classification as an interstellar object.

    In comparison, ‘Oumuamua had an eccentricity of about 1.2, and Borisov about 3.6.

    Right now, 3I/ATLAS is within Jupiter’s orbit at a distance of about 465 million km (290 million miles) from Earth and 600 million km (370 million miles) from the Sun.

    The closest the comet will come to Earth is approximately 270 million km (170 million miles) on December 19, 2025, though it will pose no threat to the planet.

    It will reach its closest approach to the Sun around October 30, 2025, at a distance of 210 million km (130 million miles) — just inside the orbit of Mars.

    During this close approach, it will be traveling almost 25,000 km (15,500 miles) per hour.

    The new image of 3I/ATLAS was captured by the Multi-Object Spectrograph (GMOS-N) at the Gemini North telescope.

    “The sensitivity and scheduling agility of the International Gemini Observatory has provided critical early characterization of this interstellar wanderer,” said Martin Still, NSF program director for the International Gemini Observatory.

    “We look forward to a bounty of new data and insights as this object warms itself on sunlight before continuing its cold, dark journey between the stars.”

    Mars was Warm and Wet 3.7 Billion Years Ago, New Study Suggests

    Planetary scientists have discovered more than 15,000 km of ancient riverbeds in Noachis Terra, a region in Mars’ southern highlands. This discovery suggests that Mars may once have been much wetter than previously thought.

    This HiRISE image shows a flat top, heavily eroded fluvial sinuous ridge on Mars; sand dunes can be seen migrating over the top of the fluvial sinuous ridge. Image credit: NASA / JPL / University of Arizona.

    The nature of the Martian climate during the Noachian-Hesperian transition, a period of geologic and climatic changes around 3.7 billion years ago, and how surface features such as valley networks and lakes associated with liquid water formed, is debated.

    There are two theories: the first is that warm and wet conditions persisted on early Mars long enough that liquid water was stable on the surface for extended periods; the second is that Mars was generally cold and dry, and that geological features indicative of flowing water were formed only very sporadically by meltwater from ice sheets during short climate excursions.

    Noachis Terra is a region where ‘warm, wet’ climate models predict high rates of precipitation.

    In new research, Open University Ph.D. student Adam Losekoot and his colleagues looked at fluvial sinuous ridges, also known as inverted channels, across this region.

    “These are believed to have formed when sediment deposited by rivers hardened and was later exposed as the surrounding material eroded,” the authors said.

    “Similar ridges have been found across a range of terrains on Mars.”

    “Their presence suggests that flowing water was once widespread in this region, with precipitation being the most likely source of this water.”

    They found fluvial sinuous ridges to be common across Noachis Terra, with a cumulative length of more than 15,000 km.

    These are often isolated segments, but some systems are hundreds of km in length.

    “Studying Mars, particularly an underexplored region like Noachis Terra, is really exciting because it’s an environment which has been largely unchanged for billions of years,” Losekoot said.

    “It’s a time capsule that records fundamental geological processes in a way that just isn’t possible here on Earth.”

    For the study, the researchers used data from three orbital instruments: the Context Camera (CTX), the Mars Orbiter Laser Altimeter (MOLA) and the High Resolution Imaging Science Experiment (HiRISE).

    These datasets allowed them to map the locations, lengths and morphologies of ridge systems across a wide area.

    “Our work is a new piece of evidence that suggests that Mars was once a much more complex and active planet than it is now, which is such an exciting thing to be involved in,” Losekoot said.

    “The fact that the ridges form extensive interconnected systems suggests that the watery conditions must have been relatively long-lived, meaning Noachis Terra experienced warm and wet conditions for a geologically relevant period.”

    “These findings challenge existing theories that Mars was generally cold and dry, with a few valleys formed by ice-sheet meltwater in sporadic, short periods of warming.”

    Meet Skydweller: A solar-powered drone that can fly for 90 days straight — it's wider and 160 times lighter than a Boeing 747

    A solar-powered aircraft at Skydweller's facility at Albacete airport on April 3, 2023, in Albacete, Castilla-La Mancha, Spain. Skydweller is a solar-powered aircraft developed by Skydweller Aero, an Albacete-based developer of aircraft for the commercial and defense sectors, which announced the successful completion of autonomous flight tests in Castilla-La Mancha.

    U.S. tech startup Skydweller Aero has teamed up with Thales, a French electronics company specializing in defense systems, to develop a new maritime surveillance drone that can stay aloft far longer than existing machines.

    Skydweller powers itself purely from solar energy and aims to be capable of continuous flight. The initial flight milestone will be for it to remain aloft for 90 days, but ultimately it has the potential to fly for much longer.

    The solar energy that powers the Skydweller is captured by over 17,000 individual solar cells, spread across approximately 2,900 square feet (270 square meters) of wing surface — across a wingspan of 236 feet (72 m), 25 feet (7.6 m) longer than a Boeing 747. In ideal conditions, the solar cells can generate up to 100 kilowatts of power for the aircraft.

    During daylight hours, solar energy is used to maintain flight, power the onboard avionics and charge batteries. The Skydweller has over 1,400 pounds (635 kilograms) of batteries, which are used to power the aircraft through the night. This will allow Skydweller to maintain almost continuous flight.

    The Skydweller typically flies at an altitude between 24,600 and 34,400 feet (7,500 and 10,500 meters), but can fly as high as 44,600 feet (13,600m) during the day, before dropping by 4,900 to 9,800 feet (1,500 to 3,000m)at night, as this minimizes power consumption.

    Despite its similar wingspan to a long-range commercial airliner, Skydweller weighs 160 times less than a "jumbo jet" — 2.5 metric tons at maximum capacity versus 400 tons for the 747 at full payload.

    Related: 

    Solar-powered aircraft are not completely new, but some designs have suffered structural problems, including catastrophic failure mid-flight when climbing or descending through medium altitudes (approximately 6,500-32,800 feet, or 2,000-10,000 m).

    The Skydweller has been specifically designed to operate in this altitude range, using automatic gust-load alleviation software in the flight control system to reduce the aerodynamic loads caused by turbulence. It has also been constructed from carbon fiber and can carry up to 800 pounds (362 kg) of payload.

    Continuous surveillance by sky

    Operating an aircraft continuously and reliably for up to 90 days necessitates a quadruple-redundant flight control system and vehicle management system (VMS). Should one of the onboard systems fail, a backup system can take over to maintain the flight.

    Self-healing algorithms within the VMS allow any failed strings (coding in an algorithm) to be autonomously shut down, corrected and resurrected during flight, thereby allowing the aircraft to return to quadruple redundancy, according to information published by company representatives. This enables the aircraft to consistently maintain flight.

    Although the onboard batteries, once sufficiently charged, can maintain flight during the night, their capacity will degrade over time, which could limit the maximum patrol duration of the aircraft. Skydweller’s reliance on solar power to maintain flight means that its patrols must also avoid areas of limited sunlight, such as polar regions during winter.

    Skydweller Aero has recently partnered with Thales to equip Skydweller with a radar surveillance system designed for maritime patrol operations. Further test flights are planned, with the goal of extending the maximum flight duration. Even so, this is a massive step forward in solar-powered flight, especially for long-term surveillance monitoring.

    Behold, 'The Beast': Gigantic animal-like plasma plume 13 times wider than Earth hovers over the sun

    Looped video footage of a large solar prominence dancing above the sun's surface

    A giant plasma plume dubbed "The Beast" was recently spotted dancing above the sun as it showered our home star with blobs of impossibly fast fire. The shapeshifting projection, which stretched more than 13 times wider than Earth, was the first of several sizable solar structures to emerge in recent days.

    The animalistic mass appeared Saturday (July 12) over the northwestern limb of the sun, allowing photographers from around the world to snap some stunning shots, including Michael Jäger, who captured the plume from Martinsburg in Austria (see above); and Simon Metcalfe, who saw it from near his home in Gloucestershire, England (see below).

    Astrophotographer Daid Wilson also captured an amazing movie of the entire event from Inverness in Scotland, revealing that the morphing plume stretched more than 100,000 miles (165,000 km) across.

    The plume was at its peak size for around three hours and constantly changed shape during this time. "It looks to me like some huge 4-legged beast shuffling along," Wilson told Spaceweather.com.

    This quote was picked up on several social media outlets, including Reddit and X, leading people to refer to the plume as "The Beast."

    The Beast is a solar prominence — a "bright feature extending outward from the sun's surface," made from ionized gas, or plasma, that is held in place by invisible magnetic field lines anchored to the solar surface, according to NASA.

    These structures are usually small but can grow to be more than 1 million miles (1.6 million km) long and can be seen hovering around the sun's disk during eclipses, such as during the 2024 total solar eclipse over North America.

    In the new images, smaller blobs of plasma can also be seen falling from The Beast toward the sun's surface. This is known as "coronal rain" and occurs when plasma cools and condenses, causing it to fall back to the sun's surface at extreme speeds as it travels along the invisible magnetic field lines.

    Prominences, which commonly form in a looped horseshoe shape, can also unleash solar storms, such as coronal mass ejections (CMEs), when the magnetic fields that hold them up snap like an overstretched elastic band, flinging the plasma off into space. If these solar storms collide with Earth's magnetic field, they can trigger geomagnetic disturbances, which can cause radio blackouts, satellite disruption and vibrant aurora displays. But in this case, no CME was released, meaning The Beast poses no threat to our planet.

    Two more large prominences have also appeared on the sun in recent days: First, on Monday (July 14), and then again on Tuesday (July 15). Both of these structures were larger than The Beast, with a much more traditional shape, and unleashed CMEs. However, due to the angle from which they were released from the sun, neither of the solar storms will hit Earth, according to EarthSky.org.

    The recent flurry of activity is a reminder that the sun is currently nearing the end of the most active phase in its roughly 11-year sunspot cycle, known as solar maximum. During this period, magnetic instabilities make it much easier for chunks of plasma to break away from the solar surface.

    Two other large prominences have appeared on the sun since "The Beast," and both released CMEs into space. The second one (pictured) occurred on on Tuesday (July 15).

    Scientists discover long-lost giant rivers that flowed across Antarctica up to 80 million years ago

    The rivers likely formed when the supercontinent Gondwana broke up, separating Antarctica from Australia.

    Scientists have discovered a long-lost landscape that's been preserved beneath the Antarctic Ice Sheet for 30 million years.

    Erosion by ancient rivers appears to have carved large, flat surfaces beneath the ice in East Antarctica between 80 million and 34 million years ago. Understanding how these features formed, and how they continue to affect the landscape, could help refine predictions of future ice loss, researchers reported July 11 in the journal Nature Geoscience.

    "We've long been intrigued and puzzled about fragments of evidence for 'flat' landscapes beneath the Antarctic ice sheets," study co-author Neil Ross, a geophysicist at Newcastle University in the U.K., said in a statement. "This study brings the jigsaw pieces of data together, to reveal the big picture: how these ancient surfaces formed, their role in determining the present-day flow of the ice, and their possible influence on how the East Antarctic Ice Sheet will evolve in a warming world."


    What Is Antarctic Sea Ice Extent? - The Marine Life Explorer

    Antarctic Sea Ice Hits 2nd-Lowest Minimum Ever Recorded (March 2025)
    If the East Antarctic Ice Sheet were to melt entirely, it could raise global sea levels by more than 160 feet (50 meters). But accurately predicting how much the ice sheet might melt in the coming years requires scientists to know its past behavior and the conditions at its base.

    In the new study, the researchers used radar data from four previous surveys to map the shape of the bedrock beneath the ice.

    "When we were examining the radar images of the sub-ice topography in this region, these remarkably flat surfaces started to pop out almost everywhere we looked," study co-author Guy Paxman, a polar geophysicist at Durham University in the U.K., said in the statement. "The flat surfaces we have found have managed to survive relatively intact for over 30 million years, indicating that parts of the ice sheet have preserved rather than eroded the landscape."

    The flat expanses, which were interspersed with deep troughs, covered a 2,175-mile (3,500 kilometers) section of the East Antarctic coastline. They likely formed before the East Antarctic Ice Sheet existed but after the supercontinent Gondwana (which contained modern-day Antarctica, Australia, Africa, and India) broke apart.

    This helped the researchers to date the flat sections to between 80 million and 34 million years ago.

    Atop these flat surfaces, the Antarctic ice moves fairly slowly. But in the troughs between them, the ice flows much faster. Meltwater may have carved these troughs by flowing through natural dips as the East Antarctic Ice Sheet expanded millions of years ago.

    The slow flow of ice above the flat surfaces could be regulating ice loss from the continent, the researchers wrote in the study. Further research, such as obtaining and analyzing rock samples from under the ice, could refine projections of future ice loss and sea level rise.

    "Information such as the shape and geology of the newly mapped surfaces will help improve our understanding of how ice flows at the edge of East Antarctica," Paxman said. "This in turn will help make it easier to predict how the East Antarctic Ice Sheet could affect sea levels under different levels of climate warming in the future."

    Strange Portals Spontaneously Appearing in the Home

    Strange Portals Spontaneously Appearing in the Home

    One outlandish feature of the world of the paranormal is the idea of portals popping up in various places. These portals are said to lead to other locations or nowhere at all, and sometimes are even said to act as doorways to other worlds that sometimes allow things from the other side to come in. Portals seem like something one would be more likely to find out in the wilderness or remote areas, but it seems that sometimes these phenomena can happen right in the safety of our own homes. 

    One strange report comes from Reddit user “GilgameshvsHumbaba,” who says this happened as he was living in a small apartment several years before telling his story. One evening, he woke up to feel someone touching his head, even though no one else was there, and when he stepped whatever it was away and looked around, he saw a square or rectangular "hole" in the air. Out of this hole shone a light, and there was a man's arm and hand protruding from it and waving around in the air. The witness says of what happened next:

    The hole" started drifting to the right and revolving toward me and I saw two young men in some other room. One was sitting and working or typing or something, and the other guy was looking at what he was doing and looking at me and looking around at my bedroom. I sat up on one arm watching them, and then I noticed that the light from their room was lighting up my room. I could see the ironing board to the left, my bookcase to the right, the floor, ceiling, and my door, which was closed. That was when I knew was really awake, and I sat up more. I think they were talking to each other, but I don't remember hearing them. I thought about getting out of bed and grabbing my clothes and just stepping through the hole into their room, but I chickened out because I wasn't sure if I would be able to come back or not.

    The "hole" started to revolve the other way until it was "sideways" to me again, and then all of a sudden it disappeared and the light was gone and it was dark again. Since I have "night blindness", it was pitch-dark to me. Finally I decided that it had just been a weird dream, so I picked up the covers and lay down and turned on my side to go back to sleep, and that's when I realized I had been sitting up the whole time, so it had to have been real.

    Well. that's it. The "hole" had smooth sides and sharp corners, no glow or fog or anything. Looking back on it now, I think the two guys were panicking because they had been seen and were trying to "close the window", or however you want to say it. I've tried to tell people what happened and they just laugh at me. I know it happened!!!! Now I want to know if it happened to other people, and if anyone reported it. I'm sure the two I saw repeated their little "experiment", so there must be more witnesses somewhere.”

    Pretty weird stuff, indeed. From Reddit user “FlashyConsequence111” we have a similarly odd tale that supposedly happened back in 2004. This supposedly happened as she and her husband were sitting out enjoying a quiet evening on their veranda, and the witness says;

    There was a fence about 5meters/15 feet away from us. All of a sudden the side of this big tree next to the fence started moving, there was no wind and the other trees were not moving, nor was the otherside of the tree. My husband and I thought an animal was going to come out of it. After about 1 minute a black hole appeared and a man, carrying some box or bag in both hands, came out of the hole, ran accross the fence for 3meters/9feet another hole appeared in front of him and he went through that hole and disappeared. The trees near the second hole were moving and shaking before it appeared and he ran into it and were shaking for about 30seconds after it closed. The man was white, dark short hair, wearing a black and red flannel shirt and black pants and looked like he was running from something, he was in a panic.

    I was in shock and amazed. I turned to my husband, he was looking at the fence eyes wide open. I said 'Oh my God! Did you see that?!!' He turned to me and said 'What?' I said 'That man came out of a wormhole and ran along the fence and went into another wormhole!, that's why the tree was shaking!' He said 'when was the tree shaking?' 'Nothing happened, we have just been sitting here'. I was shocked! I was like 'what are you saying? You don't remember?' We had just been discussing how the tree was shaking and what animal we thought was going to come out. To clarify, we had never before or since had different recollections of what we had seen together. I have only told that story to my sister and children. This is the first time publicly, there are definitely technologies we do not know about, I believe in wormholes and portholes.

    What was going on here? Many stories of portals revolve around closets, which makes sense since there has long been the spooky lore gif things in the closet that have haunted children since time unremembered. One account comes from True Ghost Tales and concerns a witness who claims that when she was just a girl, she had been watching TV in the living room with her mother when they heard her father start frantically screaming for help from elsewhere in the house. They tracked the source of the mysterious screaming to the witnesses’ bedroom and found that the door was locked, which was odd considering it was just a plain old doorknob with no lock to begin with. They stood there struggling with the anomalously jammed doorknob while the father shrieked and shouted in terror from within. At the time, they thought he was having some sort of mental breakdown, as he was an alcoholic and had been drinking heavily earlier that night; however, when they finally forced the door open, they were to find it was something altogether more bizarre. The witness says of what they saw in that room:

    My mom struggled for a few minutes trying to open the door. Finally she managed to open the door and we saw my father up in the air like if he was hanging from something then a few seconds later fell feel down. He was so scared that he sounded sober, he told us to get away from there and he ran as far away from my room, when we saw my dad he seemed almost pale looking, he had scratches on his chest as if he got into a fight or something. My mom asked him “What happened to you”? Are you Ok? The only thing that came out of my father’s mouth was, “THE DEVIL, the devil was trying to take me away with him.” At first I thought my dad was only saying that to scare me but he was serious about it, he said that the devil wanted him and was trying to bite his neck. I thought to my self, it sounds more like a vampire than the devil to me, why would the devil want to bite his neck anyways?

    The scared family retreated to the living room, where they eventually fell asleep, and the next day the father explained that when he had been in the girl’s room he had seen the closet door open by itself and heard a man’s voice issue forth from the darkness beyond before the incident, after which something dark had emerged and he blacked out. He took them to the room so that they could take a look at the closet, and this is where things get even stranger still. The witness says:

    We all went to my room then my dad opened my closet door and we saw this figure of a man standing inside my closet as if it was asleep, its arms were on his chest and he was all black, with long finger nails and he had wings. The weird thing about all this is that a few day later I saw it in my room. I was watching TV in the living room. We had the hall light on so that way it could reflect light into my room, but that night the light only reflected half way. I saw a dark shadow standing in the middle of my room, then he took his hand out and started moving his index finger asking me to come to him with his reddish yellow eyes. I was so scared that I couldn’t move at all. I was screaming for my parents but they couldn’t hear me at all, how could this be they were ten feet away from me? Anyway when I turned my head back to see him he was already next to me. All he did to me was he had lifted me up and he kissed my forehead and my neck, then he left, just like that. We never say IT again, but sometimes when I’m in the dark I feel like someone is there with me.”

    It is interesting that the whole family seems to have witnessed it, so it seems beyond just a hallucination or overactive imagination. On the site "Phantoms and Monsters," there is another account from 2009 of some sort of menacing beast in a closet. The witness claims that he woke up one night suddenly at around 3 AM, and found that he was covered in sweat and overcome with an inexplicable cold fear that was overwhelming in its intensity, although his brother was still sleeping soundly. There also seemed to be a heavy sense of someone there looming near the bedroom’s rather large walk-in closet, and the witness would say of what happened next:

    I looked around in my room hoping to see my mom watching over us from the door way of the closet (I don't know why I thought it would be her but I did). Since our nightlight was on I could see things pretty clearly. I looked to my left to see a tall figure in our closet, it had an oval like head with small eyes and appendages hanging from it's face almost like a scruffy beard but it made more sense that it would be some type of structure. It looked over the both of us up and down. At first I thought it was my mind playing tricks on me, since I could be very imaginative but what snapped me out of this is when it pushed some of the clothes hangers out the way and the fact that the window was open. It's skin looked rough and pasty almost like it was in a sauna for two years. It caught a whiff of me being awake and almost immediately I lost consciousness and control over my body. All accounts that were had from that night had not been fully remembered the following morning. Besides the fact that my sheets were in my closet instead of on my bed.

    Again, we are left here with a case that seems to be so bonkers that it is beyond an easy explanation. Just what was this thing and why would it be in that closet? Was the closet acting as some sort of a doorway to another realm? Who knows? Outdoing even these outlandish encounters is another one reported on Phantoms and Monsters, this time by a witness who had just about the strangest thing you could imagine come out of his closet when he was a boy, in around the year 1980. The witness, who claims he is now a paranormal researcher, says that when he was very young, he had been trying to get to sleep in the room he shared with his brother, and again, this was a room with a big walk-in closet. As he was lying there, the closet door began to open by itself, and the witness claims:

    One night as I was trying to get to sleep (my brother was already asleep), the door opened and I know this sounds crazy, but out came Big Bird (of the children’s show Sesame Street). I remember being frightened at first, but others came out too and they were very friendly and led me into the closet with them. All I remember at this point is that Big Bird gave me a flavored chap stick (most likely to ease my fear because I loved chap stick), and they brought me back to my bed. I went to sleep very happy over the whole experience and was not afraid anymore. I put the chap stick under my pillow after taking a tiny nibble leaving my teeth marks just to see if it was still there in the morning. The next morning, I checked and low and behold the chap stick WAS there, JUST like I remembered, and at that moment I knew for a fact it was not a dream. If it were not for that chap stick the experience probably would not have stayed with me all these years. I tried to tell my brother, but he laughed it off, as anyone would, it sounds totally crazy. Now, after reading the other accounts of similar experiences, I am wondering if it was an abduction disguised as a friendly interaction.”

    What in the world? How do we come to terms with the sheer surreality of this? The witness gives an interesting observation, in that he believes it might have been an alien abduction, with the entities taking a form that would seem nonthreatening to a child. This is a feature of some alien abduction cases, with the beings allegedly able to either shape shift or manipulate perceptions in order to take the form of whatever will best serve their purposes in the eyes of the abductee, for reasons beyond us. Is that what was going on here? How else could we explain an actual character from a children’s TV show emerging from the darkened gloom of a closet? It could have been just the imagination of a child, but the fact that the witness remembers it so vividly all of these years later is notable.

    From Your Ghost Stories comes a report of just such an experience, from the U.S. state of Pennsylvania. The witness claims that as soon as she moved out of her grandmother’s house, where she had lived for some time, she began having extremely vivid dreams of a “spirit or demon” in the closet of the room in which she had stayed. She says that she had never had these menacing dreams while she had lived there, and that they had only started after she left, as well as growing steadily in intensity. She claims that the house had always been haunted, and says of what happened next:

    We just recently moved back in October. Now, I've always known this house was haunted. Everyone has. I have had so many different experiences. (For another story I assure you.) Everything seemed fine and normal. The house is old, it creeks all night long. You hear someone calling your name. For me, it is "Belle..." Nothing unusual. I walked passed the room I used to sleep in, now my uncle's room, the other day, and I instantly felt watched. Chills ran down my spine. I felt in so much danger. I quickly scurried down the stairs and forgot about it not to long after.

     I would walk by all the time (it's en route to my room). Every time I walk by, the door creeks open. Even if it is shut the whole ways, it takes force to open that door. I was carrying my cat from my room to the living room with me one morning last week. As we walked passed my uncle's room, a deep, low, frightening growl came from my cat, then she hissed the meanest hiss, as she kept her eyes locked on the room (the door was wide open, nobody was inside). Recently, my mom has been feeling it too. The door opens slowly when she walks by, and she feels cold eyes watching her.”

    Another report from the same site is similar in nature and just as eerie. This particular report comes from the state of Virginia, from a witness who believes an actual demon inhabited the closet of their master bedroom and would use the closet to pass back and forth between worlds. The witness claims that odd activity gravitating around the closet, including loud bangs and murmuring voices at night, was so intense that he put a crucifix up by the closet to try and keep whatever it was away. There was even an incident when he said the entity pushed over his young daughter, and it would later lash out at his wife. The witness says of his experiences with the terrifying demonic force in the closet:

    It did not take long to figure out that the presence was in a large closet area which adjoined the bathroom and faced directly towards the bed in the master bedroom. The closet area never got natural sunlight and was extremely dark at night. I could feel that something was watching. The crucifix seemed to keep it out of the room but it still stared from the closet. So I did the usual "get out, this is my house," "I command you to leave." I felt that this thing was not going anywhere, that it was not scared at all, it was not moving. Not long after that we found a picture of our children on the floor and it had been smashed in the middle of the frame like something was thrown at it. One night while watching TV my wife left for work and I saw a rather large shadow fly out of the bedroom and out towards the car as she was leaving, almost as if it was chasing her. Not long after that she suffered a stroke and a major car accident, both of which left no lasting injuries.

    Was this a demon or just a very powerful spirit? Was it, like other cases we have looked at here, using the closet as some sort of portal between dimensions? In another account from the site Queenies Paranormal Playhouse, there is a report from 2005 from a frightened single mother who had just moved into a duplex in the United States with her young son and niece. Almost immediately, on the very first night, they began experiencing paranormal phenomena, such as the bedroom door opening on its own and the children complaining that “something” had touched their legs as they slept. The witness explains:

    The second night of our stay, my son and I were lying down shootin' the breeze in my room. The bedroom door that was cracked half way open had closed, then re-opened. This happened a couple of times, until we finally worked up the nerve to get up and turn on the light. The next night, my son blacked out after having (what seemed to be) a nervous break down about the ghost living in his room and closet. Now, the thing about it, is my son is a big 15 year old, and he does not scare easily! After 20 minutes, he went back to his normal self and cannot remember the incident.That same night, he went to sleep with me, and I woke up to something pulling back and forth on the door knob of my closet.  I screamed, but my son never woke up!

     Relatives have said that this place gives them bad vibes, and that sometimes, they can hear people talking. Now it is day 28, and last night, my young nephew and I were sleeping, when suddenly, he woke up screaming. He had jumped off the bed, and the bedroom closet swung open in front of him! But this morning, he can only remember standing in front of the open closet... hearing the high pitched scream of a female. I talked to the people who lived in this duplex before me, and they also lived with this ghost. Even after saying prayers and using holy water, the ghost will not leave! I'm a single mother and it took my savings to move into this place. Unfortunately, it seems we're stuck here for a long time...but this ghost is going to drive us insane!

    The United States is not the only place where such encounters have allegedly occurred, and a scary report on Phantoms and Monsters comes to us from Newfoundland, where the witness claims he lived in the late 1960s at an apartment along a place called Blackmarsh Road. He says that he was 9 or 10 years old at the time, and that he had been living there with his mother, grandparents, and three sisters at the time, and that the road had been rather well known in the area as a place pervaded by ghostly phenomena. He says that although he never actually saw anything ghostly, he sure did hear it, and it seemed to originate from a coat closet in the living room. He says:

    Sometimes, due to limited space, I slept on the sofa in the living room. In the living room was a small stove and coat closet. I remember the chimney ran next to the closet. I remember so vividly being woken up between 3-4 a.m. every morning to the sounds of a group of people conversing in the closet. To the best of my knowledge, there were six or seven people. I could not pick out what they were saying, though at the moment I could hear them very clearly. This went on until we moved. I told my mother about this at the time it was happening but, of course, it was dismissed as a child's imagination until many years later.

    He says that after he had moved away and grown up, he heard that his grandmother had also had weird experiences with the voices from the closet, and that she had finally managed to banish them by reciting the Lord’s Prayer aloud. What are we to make of reports such as this? Are these just tall tales or something more? Are these just delusions or the effects of sleep paralysis? Are they aliens, ghosts, demons, or something else? Are these really portals allowing these things to pass through some thin spot between realities? If so, it seems that portals like this can pop up in the most unexpected of places, and it might be something to think about at night when your closet is open just a crack

    Strange Portals Spontaneously Appearing in the Home

    One outlandish feature of the world of the paranormal is the idea of portals popping up in various places. These portals are said to lead to other locations or nowhere at all, and sometimes are even said to act as doorways to other worlds that sometimes allow things from the other side to come in. Portals seem like something one would be more likely to find out in the wilderness or remote areas, but it seems that sometimes these phenomena can happen right in the safety of our own homes. 

    One strange report comes from Reddit user “GilgameshvsHumbaba,” who says this happened as he was living in a small apartment several years before telling his story. One evening, he woke up to feel someone touching his head, even though no one else was there, and when he stepped whatever it was away and looked around, he saw a square or rectangular "hole" in the air. Out of this hole shone a light, and there was a man's arm and hand protruding from it and waving around in the air. The witness says of what happened next:

    The hole" started drifting to the right and revolving toward me and I saw two young men in some other room. One was sitting and working or typing or something, and the other guy was looking at what he was doing and looking at me and looking around at my bedroom. I sat up on one arm watching them, and then I noticed that the light from their room was lighting up my room. I could see the ironing board to the left, my bookcase to the right, the floor, ceiling, and my door, which was closed. That was when I knew was really awake, and I sat up more. I think they were talking to each other, but I don't remember hearing them. I thought about getting out of bed and grabbing my clothes and just stepping through the hole into their room, but I chickened out because I wasn't sure if I would be able to come back or not.

    The "hole" started to revolve the other way until it was "sideways" to me again, and then all of a sudden it disappeared and the light was gone and it was dark again. Since I have "night blindness", it was pitch-dark to me. Finally I decided that it had just been a weird dream, so I picked up the covers and lay down and turned on my side to go back to sleep, and that's when I realized I had been sitting up the whole time, so it had to have been real.

    Well. that's it. The "hole" had smooth sides and sharp corners, no glow or fog or anything. Looking back on it now, I think the two guys were panicking because they had been seen and were trying to "close the window", or however you want to say it. I've tried to tell people what happened and they just laugh at me. I know it happened!!!! Now I want to know if it happened to other people, and if anyone reported it. I'm sure the two I saw repeated their little "experiment", so there must be more witnesses somewhere.”

    Pretty weird stuff, indeed. From Reddit user “FlashyConsequence111” we have a similarly odd tale that supposedly happened back in 2004. This supposedly happened as she and her husband were sitting out enjoying a quiet evening on their veranda, and the witness says;

    There was a fence about 5meters/15 feet away from us. All of a sudden the side of this big tree next to the fence started moving, there was no wind and the other trees were not moving, nor was the otherside of the tree. My husband and I thought an animal was going to come out of it. After about 1 minute a black hole appeared and a man, carrying some box or bag in both hands, came out of the hole, ran accross the fence for 3meters/9feet another hole appeared in front of him and he went through that hole and disappeared. The trees near the second hole were moving and shaking before it appeared and he ran into it and were shaking for about 30seconds after it closed. The man was white, dark short hair, wearing a black and red flannel shirt and black pants and looked like he was running from something, he was in a panic.

    I was in shock and amazed. I turned to my husband, he was looking at the fence eyes wide open. I said 'Oh my God! Did you see that?!!' He turned to me and said 'What?' I said 'That man came out of a wormhole and ran along the fence and went into another wormhole!, that's why the tree was shaking!' He said 'when was the tree shaking?' 'Nothing happened, we have just been sitting here'. I was shocked! I was like 'what are you saying? You don't remember?' We had just been discussing how the tree was shaking and what animal we thought was going to come out. To clarify, we had never before or since had different recollections of what we had seen together. I have only told that story to my sister and children. This is the first time publicly, there are definitely technologies we do not know about, I believe in wormholes and portholes.

    What was going on here? Many stories of portals revolve around closets, which makes sense since there has long been the spooky lore gif things in the closet that have haunted children since time unremembered. One account comes from True Ghost Tales and concerns a witness who claims that when she was just a girl, she had been watching TV in the living room with her mother when they heard her father start frantically screaming for help from elsewhere in the house. They tracked the source of the mysterious screaming to the witnesses’ bedroom and found that the door was locked, which was odd considering it was just a plain old doorknob with no lock to begin with. They stood there struggling with the anomalously jammed doorknob while the father shrieked and shouted in terror from within. At the time, they thought he was having some sort of mental breakdown, as he was an alcoholic and had been drinking heavily earlier that night; however, when they finally forced the door open, they were to find it was something altogether more bizarre. The witness says of what they saw in that room:

    My mom struggled for a few minutes trying to open the door. Finally she managed to open the door and we saw my father up in the air like if he was hanging from something then a few seconds later fell feel down. He was so scared that he sounded sober, he told us to get away from there and he ran as far away from my room, when we saw my dad he seemed almost pale looking, he had scratches on his chest as if he got into a fight or something. My mom asked him “What happened to you”? Are you Ok? The only thing that came out of my father’s mouth was, “THE DEVIL, the devil was trying to take me away with him.” At first I thought my dad was only saying that to scare me but he was serious about it, he said that the devil wanted him and was trying to bite his neck. I thought to my self, it sounds more like a vampire than the devil to me, why would the devil want to bite his neck anyways?

    The scared family retreated to the living room, where they eventually fell asleep, and the next day the father explained that when he had been in the girl’s room he had seen the closet door open by itself and heard a man’s voice issue forth from the darkness beyond before the incident, after which something dark had emerged and he blacked out. He took them to the room so that they could take a look at the closet, and this is where things get even stranger still. The witness says:

    We all went to my room then my dad opened my closet door and we saw this figure of a man standing inside my closet as if it was asleep, its arms were on his chest and he was all black, with long finger nails and he had wings. The weird thing about all this is that a few day later I saw it in my room. I was watching TV in the living room. We had the hall light on so that way it could reflect light into my room, but that night the light only reflected half way. I saw a dark shadow standing in the middle of my room, then he took his hand out and started moving his index finger asking me to come to him with his reddish yellow eyes. I was so scared that I couldn’t move at all. I was screaming for my parents but they couldn’t hear me at all, how could this be they were ten feet away from me? Anyway when I turned my head back to see him he was already next to me. All he did to me was he had lifted me up and he kissed my forehead and my neck, then he left, just like that. We never say IT again, but sometimes when I’m in the dark I feel like someone is there with me.”

    It is interesting that the whole family seems to have witnessed it, so it seems beyond just a hallucination or overactive imagination. On the site "Phantoms and Monsters," there is another account from 2009 of some sort of menacing beast in a closet. The witness claims that he woke up one night suddenly at around 3 AM, and found that he was covered in sweat and overcome with an inexplicable cold fear that was overwhelming in its intensity, although his brother was still sleeping soundly. There also seemed to be a heavy sense of someone there looming near the bedroom’s rather large walk-in closet, and the witness would say of what happened next:

I remember so vividly being woken up between 3-4 a.m. every morning to the sounds of a group of people conversing in the closet. To the best of my knowledge, there were six or seven people. I could not pick out what they were saying, though at the moment I could hear them very clearly. This went on until we moved. I told my mother about this at the time it was happening but, of course, it was dismissed as a child's imagination until many years later.

    He says that after he had moved away and grown up, he heard that his grandmother had also had weird experiences with the voices from the closet, and that she had finally managed to banish them by reciting the Lord’s Prayer aloud. What are we to make of reports such as this? Are these just tall tales or something more? Are these just delusions or the effects of sleep paralysis? Are they aliens, ghosts, demons, or something else? Are these really portals allowing these things to pass through some thin spot between realities? If so, it seems that portals like this can pop up in the most unexpected of places, and it might be something to think about at night when your closet is open just a crack
