Space Junk: How Much Debris are There in Earth's Orbit?
Space Junk: How Much Debris are There in Earth's Orbit?
Ever since the space race, humankind has launched a lot of things into space and in the process have polluted our orbit. Sometimes experimental satellites went awry and turned to debris as soon as they launched, and other times space accidents created lots of space junk.
In some cases, the creation of space junk was the direct result of intentional exploding satellites, such as China destroying a defunct weather satellite with a missile that added more than 3,000 pieces to orbit. NASA estimates that there are more than half a million items larger than a marble currently floating in space. These are the ones that can be tracked! There may be millions more that cannot be tracked.
In 1963, the Project West Ford colloquially known as Project Needles, launched 500 million copper wires into orbit to form a dipole antennas so military messages could be sent coast to coast in the United States. These needles were only supposed to stay in orbit for three years, but they outlasted the initial project and remain in orbit to this day: in 2016 there were 38 clusters in existence. These items are all in constant movement and depending where they are in orbit have speeds that can reach to about 17,500 miles per hour.
The closer an object is to the Earth, the faster it travels. The debris can hit each other and other objects and lose energy, causing them to switch to lower orbits. This is potentially dangerous to active satellites, Hubble Space Telescope, and the International Space Station (ISS). In 1957, the United States Department of Defense started tracking space debris larger than a grapefruit. Presently in conjunction with NASA, they actively track approximately 21,000 items with a special satellite.
There are established protocols to address debris to protect the ISS, one is called the “Debris Avoidance Maneuver”, that moves the ISS out of the path of incoming debris. This is not as easy as it sounds, since the ISS is as big as a soccer field and weighs 450 tons. If time is to short, or the maneuver is not feasible, the ISS crew members move to the Soyuz spacecraft to prepare to return to Earth in an emergency. This has happened 3 times in history, but no space debris has caused an emergency Earth landing.
Also concerning is that even small, untraceable items can cause damage and impose danger on space activities. It is estimated that there are more than 100 million pieces smaller than 1.5 centimeters in our orbit. One of these pieces led to the the ISS to replace a window. It was determined that the damage on the window was caused simply from tiny paint flecks that were smaller than 1 millimeter.
The ISS has also sustained damage to thermal radiators and solar panels from small space debris. In late 2017, SpaceX Dragon cargo vehicle delivered the “Space Debris Sensor” that is allowing the ISS to monitor impacts caused by small-scale space debris for the following two to three years.
Obviously, this junk does not stay in orbit forever. Some will eventually lose energy due to collisions and enter Earth’s atmosphere. In fact, every week, 4400 pounds of debris uncontrollably re-enters our atmosphere.
Luckily for us on Earth, most of these objects burn up in the atmosphere upon reentry. Even if they survive beyond reentry, more than likely they will break down into smaller pieces and land in oceans. Because remember: Water covers 70 percent of the Earth’s surfaces. So, it’s unlikely that you will be hit with space debris, but the probability is not zero.
Some scientists classify our orbit as being at “critical density”. This means that “more fragments will be generated by collisions, than will be removed by atmospheric drag, even if no further objects are added.
How Will We Solve the Space Junk Problem?
There is research being done to help address this issue, such as improving detection methods and removal technologies that involve capture of space debris, laser beams to interfere with the orbit of the debris and promote decay or pushing debris further out away from satellites zones, and even upcycling old satellite parts.

There has also been an active effort in space activities to limit or prevent additional debris from being added to the orbit that will only become more important as companies are wanting to launch their own satellites. For example, SpaceX have been launching satellites into our orbit to create broadband internet. They were first granted permission to launch up to 12,000 satellites from U.S. Federal Communications Commission (FCC), but more recent requests from SpaceX indicate they want permission from the International Telecommunication Union (ITU) to launch up to 30,000 more satellites.

However, given that the aerospace initiatives may allow us to surpass the limits of our Pale Blue Dot, and allow us to spread to the Solar System and maybe eventually to the Milkyway Galaxy… We don’t think this is a dream that we can let go, just because of space debris.
But hey… Who knows? Maybe one of you who is reading this will come up with the ultimate solution to space debris that allows us to limit or not create debris during our attempts to leave Earth, to study the universe, to communicate around the Earth, to connect to the Internet and so forth.
Researchers concluded that even a contained nuclear conflict would take a toll on Earth’s oceans and potentially disrupt the human food web. “The impacts are huge,” a scientist said.
A mushroom cloud erupts during the Castle Bravo nuclear weapon test at Bikini Atoll in 1954.
You’ve likely heard of nuclear winter, a hypothesis explored by decades of scientific research. It’s the idea that – following the firestorms produced in an all-out nuclear war – the soot lifted into Earth’s stratosphere would cause serious cooling, and subsequent crop failures and famines. Now a new study has looked at how even a relatively contained nuclear conflict – for example, a hypothetical war between India and Pakistan – might shift the chemistry of Earth’s oceans. The reasoning is reminiscent of that behind nuclear winter: soot lifted into the atmosphere would cause cooling. In the new study, the researchers concluded that even a contained conflict would “take a toll” on the oceans and potentially disrupt the human food web.
Nicole Lovenduski of University of Colorado Boulder (CU Boulder) led the study. She commented in a statement:
The impacts are huge.
The journal Geophysical Research Letterspublished the new study in late January 2020.
These researchers used global climate models to conduct their simulations. They looked at four possible nuclear conflicts, including three in India/Pakistan of differing magnitudes (5 teragrams, 27 teragrams, and 47 teragrams of soot produced, respectively; a teragram is equal to one trillion grams or 1,000 kilotons), and one all-out U.S./Russia case with 150 teragrams of soot produced. Writing at LaboratoryEquipment.com, Michelle Taylor penned a succinct explanation of what would happen in even the “tamest” of the India-Pakistan simulations. She wrote:
… the researchers found that the conflict would likely generate huge amounts of black carbon high in Earth’s atmosphere, causing the globe to cool. Interestingly, the researchers found that the fallout from a nuclear detonation would come in two stages: the first within one year, and the second between three and five years post-bombing.
Soon after denotation and no longer than one year later, global climate models showed the acidity of the world’s oceans would likely dip. Years later, the world’s salt water would begin to suck up more carbon dioxide from the air. Supplies of carbonate in the oceans would shrink, removing the key ingredient that corals use to maintain their reefs and oysters use to sustain their shells.
Lovenduski told Taylor that – beyond taking a toll on crustaceans – a major disruption of the oceanic food web would undoubtedly severely impact the human food chain. Taylor wrote:
That’s because there are more than 3 billion people in the world today who depend on ocean fisheries for protein and/or income.

Brian Toon, also of CU Boulder, was a co-author on the study. He commented in the team’s statement:
This result is one that no one expected. In fact, few people have previously considered the impact of a nuclear conflict on the ocean.
Lovenduski commented:
A lot of things would change in the oceans once you dim the lights [via soot in the atmosphere]. The way the water moves in the ocean, for example, is sensitive to how much heat it gets from the atmosphere …
It makes me question whether organisms could adapt to such a change. We’re already questioning whether they can adapt to the relatively slower process of man-made ocean acidification, and this would happen much more abruptly.
Lovenduski said it’s too soon to say for sure what the fate of shelled creatures in the oceans would be if nuclear war broke out. She said she hopes that her group’s findings will bring more attention to the wide-ranging devastation that would follow even a limited nuclear exchange. There’s no such thing, she said, as a minor nuclear war, adding:
I hope this study helps us to gain perspective on the fact that even a small-scale nuclear war could have global ramifications.

A new study shows that even a limited nuclear conflict could have damaging effects on Earth’s oceans. The bombs would not have to explode over the ocean for the effects to take place.
Bottom line: Scientists used global climate models to study various scenarios involving limited nuclear conflicts. The researchers called the impacts “huge.”
These powerful storms can knock out satellites and power grids, and we may be due for one every 25 years.
On June 20, 2013, at 11:15 p.m. EDT, the sun shot out a solar flare (left side), which was followed by an eruption of solar material shooting through the sun's atmosphere.
The sun constantly bombards Earth with wispy belches of plasma called solar wind. Normally, the planet's magnetic shield soaks up the brunt of these electric particles, producing stunning auroras as they surge toward Earth's magnetic poles. But every so often, there comes a solar sneeze powerful enough to body-slam our atmosphere.
These severe space weather events — known as solar storms — compress Earth's magnetic shield, releasing enough power to blind satellites, disrupt radio signals and plunge entire cities into electrical blackouts. According to a study published Jan. 22 in the journal Geophysical Research Letters, they may be much more common than previously thought.
In the new study, researchers analyzed a catalog of Earth's magnetic field changes going back to 1868; years that showed the strongest spikes in geomagnetic activity coincided with the most severe solar storms. They found that severe storms (those capable of disrupting some satellites and communications systems) occurred in 42 of the last 150 years, while the most extreme storms — "great" superstorms, which cause significant damage and disruption — occurred in six of those years, or once every 25 years.
"Our research shows that a super-storm can happen more often than we thought," study co-author Richard Horne, a space weather researcher at the British Antarctic Survey, said in a statement. "Don't be misled by the stats. It can happen any time. We simply don't know when."
Attack of the sun
For the new study, the researchers consulted the world's oldest continuous geomagnetic index, known as the aa index.
Since 1868, the index has recorded changes in Earth's magnetic field as observed by two research stations on opposite sides of the planet, one in Australia and the other in the U.K. Every 3 hours, ground-based sensors at each station record local changes in magnetic field activity; after combining the daily averages from each station, scientists get a general picture of magnetic field activity across the entire planet.
Because the study authors were concerned only with the most extreme solar events over the last 150 years, they focused on the top 5% of geomagnetic spikes recorded each year. With this data, the authors ranked the top 10 years with the most severe geomagnetic activity from 1868 to present day. Those years, from most to least active, were 1921, 1938, 2003, 1946, 1989, 1882, 1941, 1909, 1960 and 1958.
Unsurprisingly, most of those years were associated with powerful geomagnetic storms.
"The earliest ones would have been reported in terms of auroras ('northern lights') at low latitudes, and disruptions to telegraph communications," lead study author Sandra Chapman, an astrophysics professor at the University of Warwick in England, told Live Science in an email. "As aviation and radio came into widespread use, reports centered on disruptions to those."
A geomagnetic storm in May of 1921, for example, caused widespread radio and telegraph outages across the world, resulting in at least one telegraph operator's instrument bursting into flames and setting his office on fire, according to a report published in 2001 in the Journal of Atmospheric and Solar-Terrestrial Physics. The northern and southern auroras (which intensify during solar storms) were also visible at far lower latitudes than usual, with one observatory claiming to detect the southern lights from the island of Samoa, just 13 degrees south of the geomagnetic equator.
More recent solar storms, such as a massive flare that swept over Earth on Halloween 2003, disrupted communications satellites and caused other spacecraft to tumble out of control. In March 1989, a gargantuan solar storm plunged the entire province of Quebec, Canada, into darkness and left millions of people without power for 12 hours.
Earth hasn't been hit with a solar super-storm in nearly two decades (though a large, potentially damaging solar ejection passed by us in 2012). Since then, our world has become more networked and satellite-dependent; the precise impacts the next superstorm will have on our society aren't well understood, Chapman said. Studies like this can help scientists predict the likelihood that a powerful space storm might hit Earth in a given year, which could lead to better preparedness, she added.
Powerful solar ejections occur more frequently when there are a lot of sunspots on the sun's surface. Sunspot activity tends to peak approximately every 11 years, during a period called the solar maximum. The last solar maximum occurred in 2014.
Researchers Find Presolar Grains in Unusual Inclusion from Allende Meteorite
Researchers Find Presolar Grains in Unusual Inclusion from Allende Meteorite
Scientists from Washington University, St. Louis, Caltech and the University of Chicago have found presolar grains — tiny bits of solid interstellar material formed before the Sun was born — in Curious Marie, a sample of the famous Allende meteorite.
Curious Marie is a sample of the Allende meteorite, which fell in northern Mexico in February 1969. The white, fuzzy-looking features in this fragment are calcium-aluminum-rich inclusions — some of the first solids to condense in the Solar System. Image credit: The Planetary Society.
Curious Marie is a notable example of an inclusion, or a chunk within a meteorite, called a calcium-aluminum-rich inclusion (CAI).
These objects, some of the first to have condensed in the Solar Nebula, help cosmochemists define the age of the Solar System.
“What is surprising is the fact that presolar grains are present. Following our current understanding of solar system formation, presolar grains could not survive in the environment where these inclusions are formed,” said Dr. Olga Pravdivtseva, a researcher in the Physics Department and the McDonnell Center for the Space Sciences at Washington University, Saint Louis.
In 2016, a research team from the University of Chicago discovered evidence in Curious Marie that a rare element called curium was present during the formation of the Solar System.
This fragment of the Allende meteorite and curium are named after the Nobel Prize-winning physicist and chemist Marie Curie, whose pioneering work laid the foundation of the theory of radioactivity.
In the new study, Dr. Pravdivtseva and colleagues used noble gas isotopic signatures to show that presolar grains of silicon carbide are present in Curious Marie.
That’s important because presolar grains are generally thought to be too fragile to have endured the high-temperature conditions that existed near the birth of our Sun.
But not all CAIs were formed in quite the same way.
“The fact that silicon carbide is present in refractory inclusions tells us about the environment in the Solar Nebula at the condensation of the first solid materials,” Dr. Pravdivtseva said.
“The fact that silicon carbide was not completely destroyed in Curious Marie can help us to understand this environment a little bit better.”
“Many refractory inclusions were melted and lost all textural evidence of their condensation. But not all.”
The scientists had 20 mg of Curious Marie to work with, which is a relatively large sample from a cosmochemistry perspective.
They heated it up incrementally, increasing temperature and measuring the composition of four different noble gases released at each of 17 temperature steps.
“Experimentally, it is an elegant work. And then we had a puzzle of noble gas isotopic signatures to untangle. For me, it is like solving a mystery,” Dr. Pravdivtseva said.
Other scientists have looked for evidence of silicon carbide in such CAIs in meteorites using noble gases before, but Dr. Pravdivtseva’s team the first to find it.
“It was beautiful when all noble gases pointed to the same source of the anomalies — silicon carbide,” Dr. Pravdivtseva said.
“Not only do we see silicon carbide in the fine-grained CAIs, we see a population of small grains that formed at special conditions.”
“This finding forces us to revise how we see the conditions in the early Solar Nebula.”
The results were published in the journal Nature Astronomy.
It's always sunny for heliophysicists, but especially so now.
The Solar Orbiter spacecraft, a collaboration between the European Space Agency and NASA, launched yesterday (Feb. 9), less than two weeks after the first public image from a massive new solar telescope showed off the structure of our star in more detail than humans have ever seen. On that same day, Jan. 29, NASA's Parker Solar Probe made its closest swing pass the sun to date — a record it will continue to break until 2025.
"It's a great time to be a heliophysicist; we're launching lots of new missions," Nicky Fox, head of NASA's Heliophysics Division, told Space.com. "It's a very strategic way that we're looking at this system [of instruments], as one large observatory."
Although the three missions weren't designed as a suite, they complement one another well. The Parker Solar Probe, which launched in August 2018, is flying closer to the visible surface of the sun than any spacecraft to date. That trajectory carries the spacecraft deep into the sun's atmosphere, called the corona, where the probe's instruments focus on the spacecraft's immediate surroundings, measuring magnetic fields and particles of plasma, the charged soupy state of matter that makes up the sun.
Solar Orbiter won't fly as close to the sun, but it brings unique skills. First, it carries two types of instruments. One set, like Parker's, will study the spacecraft's surroundings; the other, a set of telescopic instruments, will observe the visible surface of the sun itself at a distance. And partway through its mission, Solar Orbiter will leave the belt around the sun's middle, called the ecliptic, and begin circling the sun at a tilt, allowing the spacecraft to use those telescopic instruments to produce the first-ever images of the sun's poles.
The National Science Foundation's Inouye Solar Telescope is stuck here on Earth, and construction is still underway. But once all of its instruments are operational, there will be plenty more images like the "caramel corn" picture that scientists published in January — the highest-resolution solar image to date. "The Inouye Solar Telescope is a microscope on the sun," Valentin Martínez Pillet, director of the National Solar Observatory, which runs the facility, told Space.com. The observatory will also measure the wavelengths of light emitted by the sun and decipher the magnetic signature of light that is under the influence of the sun's magnetic field.
Although the three projects are separate endeavors, both scientists said they and their colleagues are awfully excited about pulling all the data together.
We have so few close-up observations of the sun that being able to compare two separate locations is automatically valuable, no matter where each spacecraft is. Solar Orbiter's final schedule was dependent on its precise launch date, but as mission personnel evaluated how each timetable aligned the spacecraft with the Parker Solar Probe's close approaches, they found intriguing opportunities regardless of the launch date, Fox said.
The Inouye Solar Telescope is even easier to integrate into an observational program, Martínez Pillet said; its personnel know precisely where the two spacecraft will be at any given time and can match up the telescope accordingly.
Combining the data from all three observatories is vital for scientists to accomplish the goal that drives the missions: to understand the sun and its influence throughout the solar system. The impacts of the sun's antics ripple across the solar system as a set of phenomena called space weather.
In Earth's neighborhood, space weather can interfere with the technology modern society is ever more reliant upon, particularly navigation and communication satellites. Space weather is also a hazard for astronauts traveling farther from Earth, as it can harm both their technology and their bodies. Ultimately, solar scientists want to be able to predict space weather in much the same way meteorologists predict terrestrial weather. "We are 50 or 100 years lagging from what terrestrial weather is in terms of prediction," Martínez Pillet said.
That's because scientists just don't know enough about how the sun works. "We're able to predict a single second on the sun," he said. "I'm exaggerating — well, no, I don't think I'm exaggerating. We're not able to have any realistic predictive capabilities today, but as soon as you get the physics right, then you start being able to develop predictive capabilities."
One particular challenge in understanding space weather is the sheer distance involved, and that's where the trio of missions will be valuable, Martínez Pillet said. "One space-weather event has a combination of scales," he said. "It's triggered at really small scales, and it's a huge thing that propagates all over the heliosphere and probably can hit several planets at the same time." But by the time space weather reaches Earth, it's been influenced by millions of miles of space; it's much fresher where the Parker Solar Probe and the Solar Orbiter can study it.

There's another reason to understand space weather: It could tell scientists where to look for signs of life elsewhere in the universe. After all, while we humans have a soft spot for the sun, it's just a star like any other — which means that scientists can apply what these three missions discover to all the stars we'll never be able to see as clearly. And while space weather is vexing to Earth, it could be deadly in solar systems that surround smaller, more active stars.
And there should be plenty for the trio of projects to study in the coming years. Right now, the sun is pretty quiet, but over the next five or six years, the sun's activity will increase — and both the Parker Solar Probe and the Solar Orbiter will be on hand to see what happens during that period.
"They are really, truly voyages of discovery, and we're doing fundamental physics and understanding how a star works," Fox said.
Of course, even three high-powered missions won't solve every mystery about the sun.
"We know right now what we don't know, but we're going to find a whole lot more things that we don't know," Fox said. "That's why it's nice that these missions are so long, so you have time to develop these new questions, this new thirst for knowledge."
The Mars 2020 rover, which NASA will be launching in July, is packing serious heat.
Part of the rover’s mission is to search for fossils or other evidence that Mars once hosted life — and NASA decided that the best way to do that is to use a laser so strong it can vaporize rocks, according to Digital Trends. It’s a bizarre plan, but one that could finally determine whether the Red Planet ever hosted life.
Shoop Da Whoop
The plan is to use spectroscopic tools that can determine what those rocks were made of as they’re being blasted to kingdom come.
The laser can bring Mars rocks up to 18,000 degrees Fahrenheit, according to Digital Trends, at which point a camera would scan the resulting plasma to determine its chemical makeup.
Gratata
The goal is to spot specific minerals and compounds that are likely to form from exposure to water, like carbonates and sulfates, as they would help piece together crucial details about Mars’ former environments, such as whether the planet was ever hospitable enough for organisms to survive on the surface.
And if there’s life out there now, its first encounter with Earth be seeing a robot blasting rocks with a laser.
The full moon you’ll see this weekend will rise at sunset. It’ll be highest up in the middle of the night when the sun is below our feet. It’ll set when the sun rises. But why does it look full?
A full moon is opposite the sun. We see all of its dayside.
The coming full moon is February 9 at 07:33 UTC. That means the night of February 8-9, 2020, will bring the fullest moon for those in the Americas. The moon appears full to the eye for two to three nights. However, astronomers regard the moon as full at a precisely defined instant, when the moon is exactly 180 degrees opposite the sun in ecliptic longitude.
It’s that feature of a full moon – the fact that it’s opposite the sun as viewed from Earth – that causes a full moon to look full.
A kiss under the full moon of November 3, 2017, via our friend Steven Sweet of Lunar 101-Moon Book. He was at Port Credit, a neighborhood in the city of Mississauga, Ontario, Canada … at the mouth of the Credit River on the north shore of Lake Ontario.
Why does a full moon look full? Remember that half the moon is always illuminated by the sun. That lighted half is the moon’s day side. In order to appear full to us on Earth, we have to see the entire day side of the moon. That happens only when the moon is opposite the sun in our sky.So a full moon looks full because it’s opposite the sun.
That’s also why every full moon rises in the east around sunset – climbs highest up for the night midway between sunset and sunrise (around midnight) – and sets around sunrise. Stand outside tonight around sunset and look for the moon. Sun going down while the moon is coming up? That’s a full moon, or close to one.
Just be aware that the moon will look full for at least a couple of night around the instant of full moon.
Often, you’ll find two different dates on calendars for the date of full moon. That’s because some calendars list moon phases in Coordinated Universal Time, also called Universal Time Coordinated (UTC). And other calendars list moon phases in local time, a clock time of a specific place, usually the place that made and distributed the calendars. Translate UTC to your local time.
Want to know the instant of full moon in your part of the world, as well as the moonrise and moonset times? Visit Sunrise Sunset Calendars, remembering to check the moon phases plus moonrise and moonset boxes.
If a full moon is opposite the sun, why doesn’t Earth’s shadow fall on the moon at every full moon? The reason is that the moon’s orbit is tilted by 5.1 degrees with respect to Earth’s orbit around the sun. At every full moon, Earth’s shadow sweeps near the moon. But, in most months, there’s no eclipse.
A full moon normally passes above or below Earth’s shadow, with no eclipse.
Bottom line: A full moon looks full because it’s opposite the sun. Its lighted face is turned entirely in Earth’s direction. The next full moon is February 9 at 07:33 UTC. (Translate UTC to your time).
A multi-university team of researchers from Japan recently used the world’s fastest astrophysics-simulation supercomputers to develop an AI system capable of predicting the structure of the universe itself. The scientists hope that in doing so they’ll unlock the mysteries surrounding dark matter and dark energy.
Dubbed “Dark Emulator,” the AI system parses gigantic troves of astrophysics data and uses the information to build simulations of our universe. It taps into a massive database full of information gleaned from special telescopes and compares current data with what scientists expect based on theories surrounding the universe’s origin.
The simulation basically attempts to demonstrate what the universe might look like, including its edges, based on the big bang theory and the subsequent rapid expansion that continues to take place.
According to Phys.Org, the lead author on the team’s research paper, Takahiro Nishimichi, said:
We built an extraordinarily large database using a supercomputer, which took us three years to finish, but now we can recreate it on a laptop in a matter of seconds. I feel like there is great potential in data science.
Using this result, I hope we can work our way toward uncovering the greatest mystery of modern physics, which is to uncover what dark energy is.
The hope here is that by understanding the general cosmology of the entire universe, scientists will be able to from better theories on how dark matter works. We currently assume that most of the universe is made up of dark matter. The “void of space” as it were, isn’t a void but composed of energized matter that, so far, can’t be directly observed.
But we’re currently unable to prove dark matter exists through scientific rigor, observation, and measurement. And that leaves astrophysicists struggling to come up with a unified theory of the universe that encompasses all the different ideas in play. How do we reconcile the Big Bang, Heisenberg’s Uncertainty Principal, Einstein’s Relativity, and Newton’s Laws of thermodynamics with modern quantum mechanics and dark energy theories?
The team from Japan hopes we do so with the information we’re able to glean from Dark Emulator. The AI system doesn’t just analyze data for loose ends, it learns from each simulation it creates and uses the output to inform the next iteration.
It does this by analyzing the invisible tendrils between galaxies and performing astronomical (literally) feats of mathematics to create more precise simulations. According to a paper the team published in Astrophysical Journal, it’s incredibly accurate:
The emulator predicts the halo–matter cross-correlation, relevant for galaxy–galaxy weak lensing, with an accuracy better than 2% and the halo autocorrelation, relevant for galaxy clustering correlation, with an accuracy better than 4%.
Eventually, this technology could help flesh out our understanding of the universe and allow scientists to determine exactly what dark matter is and how dark energy works. For now, this means filling in some of the massive blanks we have in our understanding of what the universe actually looks like beyond our front porch.
But in the future, having a clear understanding of dark energy could bring about myriad far-off science fiction technologies such as warp drives, time-travel, and teleportation. That is, of course, if dark matter even exists.
We think of Uranus and Neptune almost as twins. In some ways, they are very similar. But a new study by researchers at PlanetS explains why, in some aspects, they are also radically different.
Uranus (left) and Neptune (right). While the 2 ice giant planets have similarities, they also have significant differences, which might be explained by impacts from other large bodies in the early solar system.
We tend to lump Uranus and Neptune together in our thoughts, almost as if they’re twin worlds. They are nearly the same size – bigger than Earth, but smaller than Jupiter or Saturn – and both are bluish or bluish-green, with deep atmospheres and icy interiors. But, though superficially similar, Uranus and Neptune are really quite different. They’re more different from each other than most people think. And, though their differences still haven’t been fully explained, it now seems that mighty collisions with careening planet-sized bodies – early in solar system history – might be the key.
Researchers of the National Centre of Competence in Research PlanetS (PlanetS) at the University of Zurich in Switzerland ran computer simulations to explore the role of collisions in shaping the differences between Uranus and Neptune. The findings were announced by PlanetS on February 4, 2020, with the associated research paper first published on November 22, 2019.
Uranus and Neptune are the two most distant known major planets in our solar system. Both are now considered ice giants. Both are fundamentally different from the larger gas giants Jupiter and Saturn, and from smaller rocky worlds like Earth. Uranus and Neptune have similar masses and internal compositions. Their outer atmospheres are composed of hydrogen, helium and methane, while their mantles are a combination of water, ammonia and methane ices, and their cores are a mix of rock and ice.
Uranus tends to have a blander appearance than Neptune and is mostly cloudless. Neptune’s atmosphere has darker bands than that of Uranus, with streaks and wisps of white clouds, as well as a large “dark spot.”
But there are also more significant differences between the two worlds, and the researchers wanted to know why. According to a statement by Christian Reinhardt, one of the PlanetS members:
… there are also striking differences between the two planets that require explanation.

Another team member, Joachim Stadel, pointed out that, unlike Neptune and Earth and most other major planets in our solar system, Uranus doesn’t rotate around an axis that lies nearly perpendicular with respect to the plane of its orbit. Instead:
… Uranus and its major satellites are tilted about 97 degrees into the solar plane, and the planet effectively rotates retrograde with respect to the sun.
Another key difference is that the larger moons of Uranus are in stable orbits that are aligned with the tilt of the planet. But Neptune’s largest moon, Triton, circles the planet at a very inclined orbit.
These differences suggest that Uranus’ moons formed from the same disk of dust and gas that the planet itself did, while Triton was probably once a separate object captured by Neptune’s gravity.
According to the researchers, these and other differences point to different kinds of impacts that affected the two planets long ago.
Size comparison of Earth and Neptune. According to the new study, objects with about 1 to 3 Earth masses collided with both Uranus and Neptune after they formed. Uranus was just grazed, while Neptune suffered a head-on impact.
The researchers ran computer simulations in order to explore a range of different possible collisions on both planets. From the paper:
Despite many similarities, there are significant observed differences between Uranus and Neptune: while Uranus is tilted and has a regular set of satellites, suggesting their accretion from a disk, Neptune’s moons are irregular and are captured objects. In addition, Neptune seems to have an internal heat source, while Uranus isin equilibrium with solar insulation. Finally, structure models based on gravity data suggest that Uranus is more centrally condensed than Neptune. We perform[ed] a large suite of high-resolution SPH simulations to investigate whether these differences can be explained by giant impacts.
For Uranus, we find that an oblique impact can tilt its spin axis and eject enough material to create a disk where the regular satellites are formed. Some of the disks are massive and extended enough, and consist of enough rocky material to explain the formation of Uranus’ regular satellites.
For Neptune, we investigate whether a head-on collision could mix the interior … We find that massive and dense projectiles can penetrate towards the center and deposit mass and energy in the deep interior, leading to a less centrally concentrated interior for Neptune.
We conclude that the dichotomy between the ice giants can be explained by violent impacts after their formation.
It is often assumed that both planets formed in a similar way.
But these results show that their formations – or at least their very early history – were not so similar as first thought.
Neptune and its largest moon, Triton, whose orbit is highly inclined. Triton’s orbit suggests it was captured by Neptune’s gravity. Meanwhile, the moons of Uranus likely formed in the same disk of gas and dust that Uranus did.
In one scenario, where Uranus and Neptune start off as being more similar, it was found that an impact with a body of one to three Earth masses could explain the differences we see today. If the object just grazed Uranus instead of a head-on collision, the planet’s interior would not be affected but the impact would still be enough to tilt the planet.
Conversely, if Neptune did experience a head-on impact, the collision would have affected the planet’s interior but would not form a disk of debris. This would explain why Neptune doesn’t have any large moons in regular orbits. A large heat flux on Neptune also points to the interior being remixed in a massive collision.
The simulations show how the two planets probably started off being much more similar, but the different kinds of collisions altered them significantly. As team member Ravit Helled said:
We clearly show that an initially similar formation pathway to Uranus and Neptune can result in the dichotomy observed in the properties of these fascinating outer planets.
Comparison of the interior structures of the 2 gas giants, Jupiter and Saturn, and the 2 ice giants, Uranus and Neptune. Earth is to scale.
The results of this study show how random events – like planetary collisions with other large bodies in the early solar system – can decidedly affect the future evolution of a planet. Uranus and Neptune are the worlds we see today because of such events, this study says. What if neither planet had been hit? What if Neptune had just been grazed instead of Uranus? What would these ice giants be like today in such circumstances? We don’t know, but knowing more about how they could have been affected will help scientists better understand the formation of these types of planets, as well as the gas giants like Jupiter and Saturn, and rocky worlds like Earth, Mars, Venus, and Mercury.
With a better understanding of how the planets in our own solar system formed and evolved, we can then also apply that knowledge to the study of worlds in distant solar systems.
Bottom line: A new study by researchers at PlanetS sheds light on why Uranus and Neptune are similar in some ways, but radically different in others. It seems collisions – early in solar system history – are the key.
The UFO phenomenon has many aspects that are all increasingly weirder than the last. It is often difficult to ascertain just what we are dealing with, and such accounts can really run the range from the merely odd to the downright absurd. Among all of these reports one can find certain strings of reports that don’t seem to really fit into any particular mold, and definitely one of these was a strange flap of anomalous green fireballs that appeared over a period of a couple of years over New Mexico, in the United States, which are mostly an obscure oddity but which still have never been solved.
The strange phenomena known as the “green fireballs” can best be tracked back to December 5, 1948, when a USAF C-47 transport plane crew was on their way from Lowry Air Force Base, Colorado, to Williams Air Force Base in Chandler, Arizona. It had been a fairly routine flight until they got near Las Vegas and observed an eerie green light described as a “green ball of fire” illuminating the sky to the west of the city, followed by another not long after. At around the same time, another plane in the vicinity reported the same thing, describing it as pale green with a pale green trail, and saying that the light seemed to be coming towards them, fast enough that they took evasive maneuvers to avoid a collision. The crew at first thought it might be a meteorite but they dismissed this due to the fact that the object was too low to the ground and not moving fast enough. One pilot would say of the object:
Take a soft ball and paint it with some kind of fluorescent paint that will glow a bright green in the dark… Then have someone take the ball out about 100 feet in front of you and about 10 feet above you. Have him throw the ball right at your face, as hard as he can throw it. That’s what a green fireball looks like.

Interestingly, while it was mostly thought that this was clearly a meteorite, when a Dr. Lincoln LaPaz, head of the University of New Mexico’s Institute of Meteoritics was sent to the area where it was believed the object should have fell based on its reported flight path there was no sign of any impact and no trace of a meteorite. On December 8, 1948, sightings of these strange green lights would continue, when a Beech T-7 on its way from Kirkland AFB to Las Vegas when the pilot and co-pilot saw a brilliant green light about 2,000 ft above them, which was headed their way at high speed and with a trajectory described as “flat and parallel to the ground.” The researcher LaPaz would once again step in to investigate and learn that there had been several other sightings of these green balls of light, all of them near the Los Alamos National Laboratory in New Mexico and Sandia atomic-weapons laboratory, as well as at other key military and sensitive installations in the region such as radar stations, nuclear reactors, and fighter-interceptor bases around the country. Why? No one knows.
Making it all rather intriguing was that most of these sightings were being made by trained observers and reliable witnesses such as pilots, weather observers, scientists, intelligence officers and other military personnel, who were unlikely to be making this all up or making mistakes as to what they were seeing. During his investigation LaPaz was also unable to uncover any evidence of meteorite activity, nor that there had been ever any rocket or flare tests in the areas where these sightings were taking place during those time frames. He also was beginning to doubt the meteorite theory by this point, because of the horizontal trajectories of the objects and the fact that green was not considered to be a usual color for meteorites, with him saying of the strange phenomenon:
The fireballs are Kelly green, whereas meteors are red, yellow, blue, or white. A green color could be caused by large amounts of copper, but this element is rarely found in ordinary fireballs. It could also originate from certain man-made atomic fuels. They make no noise. None of the observers of green fireballs, nor persons in the area of the balls, have report any sound whatsoever. Also the fact that they disappear and no fragments have been found on the earth, may be evidence that their flight is controlled.
Sightings of the strange green balls of fire would continue coming in over the coming month, with LaPaz himself seeing one of them on December 12th near Santa Fe that due to its perfectly horizontal trajectory, color, speed, and the way it wobbled convinced him this was no meteor. He would later ascertain that the object had passed directly over the Los Alamos laboratory and had been seen by several other witnesses in the area. A particularly spectacular sighting was made on December 20, when a patrol at Los Alamos observed several luminescent green lights descend rapidly at an angle of 45 degrees, only to then level off and continue on a horizontal pathway out of sight. On this occasion there was even mention made of what looked like an exhaust trail, similar to that of a rocket. Making it more curious is that when these sightings were reported the Air Force was quick to keep it all under wraps, even going as far as to halt the press release on the incident because of “pressure from other agencies also investigating this occurrence.” The story still managed to get out, and in a Feb 29, 1949 edition of the local newspaper Skyliner it was written of the secrecy:
A call to El Paso, Tex., brought official denial from D. K. Brown, head of the Federal Bureau of Investigation district that embraces Los Alamos, that his agency had not been called to deal with the matter. At the information or thought-control office officials indicated that they knew about the recurring green flame in the sky but indicated that it wouldn’t be wise to write about it. Capt. Carroll Tyler, project manager, said simply that all he knew about the lights was rumor — the same rumors that everyone is hearing.
Why was there so much official denial over these sightings? Who knows? Sightings would continue into the next year, when there were more reports into January. One notable account occurred on January 30, 1949, when an extremely bright green fireball was observed over New Mexico by over one hundred witnesses, including trained military personnel, oil workers, aircrew, control tower personnel, all of who described the same thing and noted that the object was completely silent. Sightings would keep on coming in right on into the following year, when pilot Captain A. Harvey and co-pilot Merrick C. Marshall saw a green fireball as they were approaching Albuquerque from Gallup, New Mexico. The Dec. 18, 1950 edition of the Albuquerque Journal would say of the encounter:
The two flyers reported that the light first appeared in the northeast, approximately over Las Vegas. They watched the light for ten minutes, they said, as it moved in the direction of Las Alamos. During that time the “greenish fireball” seemed to circle Los Alamos and then head directly toward Albuquerque. In turning, the light changed from green to a very bright white and passed over and to the rear of their plane — then near Albuquerque — at an estimated speed of over “700 miles an hour.” The time when the light was first sighted was at exactly 11:25 p.m. It remained in view until 11:35. Both pilots are experienced airmen and said it could not possibly have been another plane.
After this the sightings of the green fireballs sort of peter out and we are left to search for answers. Theories have abounded as to what could have caused the 1948-1950 green fireball flap of the Southwest. The meteor theory was largely put to rest by LaPaz, who could find no evidence whatsoever that meteorites were to blame and also pointed out time and time again that the objects displayed very uncharacteristic features for meteorites. Another idea is that it was caused by the phenomenon called ball lightning, which is in itself little understood and entails hovering orbs of electricity that appear and then blink out of existence. Still other ideas are that this was evidence of top secret aircraft or rocket tests, fallout-debris clouds associated with top-secret atomic testing, or Soviet spy technology, which might explain why they were always seen near these government installations. Of course there is also the idea that these were UFOs or even probes dropped from larger alien spacecraft. What was at the heart of the deluge of green fireball accounts reported by so many during this time span? Was this meteors, atmospheric phenomena, or visitors from another world? We didn’t know then, and we don’t know now. It remains a mystery.
ESA’s sun-exploring Solar Orbiter will be the first spacecraft ever to fly over the sun’s poles. It’ll study the origin of the solar wind, which has the potential to affect earthly technologies.
ESA’s new sun-exploring mission Solar Orbiter blasted to space this morning aboard a U.S. Atlas V 411 rocket from NASA’s spaceport in Cape Canaveral, Florida. Liftoff took place as expected at 04:03 UTC on Monday, February 10, 2020 (11:03 p.m. EST Sunday, February 9).
Solar Orbiter carries a set of 10 instruments for imaging the surface of the sun and studying its environment. It’ll get as close to the sun as 25 million miles (42 million km); that’s about a quarter of the distance between the sun and Earth. Solar Orbiter will be the first spacecraft to fly over the sun’s poles. It’s expected to shed new light on what gives rise to solar wind, which can affect earthly technologies including electric grids and communications satellites.
Solar Orbiter … will provide the first-ever images of the sun’s poles and the never-before-observed magnetic environment there, which helps drive the sun’s 11-year solar cycle and its periodic outpouring of solar storms.
Solar Orbiter will take the first direct images of the sun’s poles, but getting into the right orbit to do this means taking a loopy path through the inner solar system, borrowing thrust from the powerful gravitational fields of Earth and Venus.
The animation below,from ESA, shows the trajectory of Solar Orbiter around the sun, highlighting the gravity assist maneuvers that will enable the spacecraft to change inclination to observe the sun from different perspectives.
Bottom line: ESA’s sun-exploring Solar Orbiter mission lifted off successfully from Cape Canaveral, Florida, on February 10, 2020.
Something in Deep Space Is Sending Signals to Earth in Steady 16-Day Cycles
Something in Deep Space Is Sending Signals to Earth in Steady 16-Day Cycles
Scientists have discovered the first fast radio burst that beats at a steady rhythm, and the mysterious repeating signal is coming from the outskirts of another galaxy.
A mysterious radio source located in a galaxy 500 million light years from Earth is pulsing on a 16-day cycle, like clockwork, according to a new study. This marks the first time that scientists have ever detected periodicity in these signals, which are known as fast radio bursts (FRBs), and is a major step toward unmasking their sources.
FRBs are one of the most tantalizing puzzles that the universe has thrown at scientists in recent years. First spotted in 2007, these powerful radio bursts are produced by energetic sources, though nobody is sure what those might be. FRBs are also mystifying because they can be either one-offs or “repeaters,” meaning some bursts appear only once in a certain part of the sky, while others emit multiple flashes to Earth.
Pulses from these repeat bursts have, so far, seemed somewhat random and discordant in their timing. But that changed last year, when the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project (CHIME/FRB), a group dedicated to observing and studying FRBs, discovered that a repeater called FRB 180916.J0158+65 had a regular cadence.
The CHIME/FRB team kept tabs on the repeating burst between September 2018 and October 2019 using the CHIME radio telescope in British Columbia. During that period, the bursts were clustered into a period of four days, and then seemed to switch off for the next 12 days, for a total cycle of about 16 days. Some cycles did not produce any visible bursts, but those that did were all synced up to the same 16-day intervals.

“We conclude that this is the first detected periodicity of any kind in an FRB source,” the team said in a paper published on the preprint server arXiv in late January. “The discovery of a 16.35-day periodicity in a repeating FRB source is an important clue to the nature of this object.”
Scientists recently tracked down this particular FRB to a galaxy called SDSS J015800.28+654253.0, which is a half a billion light years from Earth. That may seem like a huge distance, but FRB 180916.J0158+65 is actually the closest FRB ever detected.
But while we know where it is, we still don’t know what it is. To that point, the beat of the FRB suggests that it might be modulated by its surroundings. If the source of the FRB is orbiting a compact object, such as a black hole, then it might only flash its signals toward Earth at a certain point in its orbital period. That scenario could potentially match this recognizable 16-day cycle
It’s also possible that we are witnessing a binary system containing a massive star and a super-dense stellar core known as a neutron star, according to a study published on arXiv on Wednesday by a separate team that looked at the same data. In that model, the neutron star would emit radio bursts, but those signals would be periodically eclipsed by opaque outflowing winds from its giant companion.
Another scenario is that the FRB rhythm isn’t tempered by another object, and is sending out the pulses directly from the source. Scientists have previously suggested that flares from highly magnetized neutron stars, called magnetars, might be the source of some FRBs. But since magnetars tend to rotate every few seconds, a 16-day cycle does not match the expected profile of a magnetar-based FRB.
Ultimately, the CHIME/FRB team hopes to find similar patterns in the handful of known repeating bursts to see if these cycles are common. The researchers also plan to keep a careful eye on FRB 180916.J0158+6 while it is active in order to spot any other details that might point to its identity.
FRBs have baffled scientists for more than a decade, but new facilities such as CHIME are revealing new details about these weird events every year. While we still don’t know what is blasting out these bizarre signals, the discovery of a clear tempo from one of these sources provides a significant lead for scientists to follow.

Iets of iemand stuurt vanuit de ruimte signalen naar de aarde, en wetenschappers weten niet waarom
Astronomen hebben een mysterieuze radiobron ontdekt in een sterrenstelsel op 500 miljoen lichtjaar van ons zonnestelsel die periodiek signalen uitzendt.
Vier dagen lang produceert de bron ieder uur één tot twee zogeheten snelle radioflitsen. Vervolgens blijft het 12 dagen stil en daarna begint de cyclus weer opnieuw.
Sterrenkundigen hebben in de afgelopen 15 jaar al zo’n 150 radioflitsen ontdekt. Slechts 10 daarvan blijken zich te herhalen.
Patroon
In een enkel geval is ook de bron van de radioflits vastgesteld.
Het mysterieuze signaal, FRB 180916.J0158+65, is al in 2017 ontdekt, maar blijft zich nog altijd herhalen.
Wetenschappers hebben nu 28 flitsen bestudeerd die zijn waargenomen tussen september 2018 en oktober 2019.
Ze slaagden erin om een patroon te ontwaren, wat nog niet eerder is gelukt bij snelle radioflitsen.
Object
De flitsen zijn afkomstig uit SDSS J015800.28+264253.0, een sterrenstelsel op zo’n 500 miljoen lichtjaar van de aarde.
Er zijn verschillende mogelijke verklaringen voor het fenomeen.
Eén mogelijkheid is dat het gaat om een object dat rond een ster draait en dat af en toe signalen uitzendt.
Buitenaardse wezens
Het kan ook een signaal zijn van een neutronenster.
Daarnaast bestaat de mogelijkheid dat de signalen afkomstig zijn van buitenaardse wezens die proberen contact te maken met andere levensvormen.
De onderzoekers blijven het object nu in de gaten houden in de hoop meer te weten te komen over de bron van de signalen.

This is a flying saucer hidden in a cloud over Nevada?
This is a flying saucer hidden in a cloud over Nevada?
This footage was taken in Nevada on January 29, 2020 on the break of dawn.The witness noticed a huge flying saucer shaped cloud which looks like a huge craft hiding in a cloud.
Lenticular clouds are often comparable in appearance to a flying saucer and probably it is just a regular cloud.
But I have my suspicions since there are undoubtedly man-made or extraterrestrial flying objects with cloaking capabilities that are kept secret from the public.

New footage of a bright unidentified flying objects in the sky above Desert Hot Springs, also known as DHS, a city in Riverside County, California, United States. This happened on 7th February 2020.
Witness report:
My wife and visiting desert hot springs for the mineral waters that we do every year this time of year. We where headed towards yucca valley to visit. On Indian Canyon road going west towards highway 62 that take you to yucca valley. My wife is a birdwatcher for decades. She spotted the string of lights that she first thought they where white pelicans. Based on the flight pattern and how the lights changed shape and direct we knew it wasn’t birds. The sighting flew over head while we where driving and passed us fast going northwest towards the mountains. I pulled over to get video and photos off my iPhone. The lights or more like different shaped orbs numbers changed from 20 to 35 objects every time it changed directions.
Listen to the eerie magnetic 'song' Earth sings during a solar storm
Listen to the eerie magnetic 'song' Earth sings during a solar storm
Scott Sutherland Meteorologist/Science Writer
Monday, November 18th 2019, 5:40 pm - As if auroras weren't eerie enough, satellites have recorded bizarre 'sci-fi music' as solar storms passed by Earth
Solar storms can result in some spectacular and bizarre effects here at Earth. Brilliant auroras splash colours across the sky, we can experience fluctuations in our power grids, and satellites can record amazing effects in space.
In a new paper, published this week in the journal Geophysical Research Letters, a team of scientists looking through old data collected by the European Space Agency's Cluster mission, discovered something remarkable.
Earth's magnetic field emits waves in response to space weather, and these waves become far more complex and energetic when a solar storm sweeps past the planet.
Converting the magnetic data from two of these solar storms to audio, the researchers are treating us to the 'eerie sci-fi music' that Earth 'sang' during these events.
The Cluster mission's four satellites were designed to orbit through Earth's magnetic field, taking readings to show how the field reacts to the solar wind and the passage of solar storms.
This artist's rendition of the ESA's Cluster mission shows the four satellites in formation as they orbit the Earth, observing how the planet's magnetic field reacts to space weather.

Combing through years of data from the mission, the researchers discovered six times when the satellites recorded a solar storm impacting on the foreshock region - the part of Earth's magnetic field that faces towards the Sun and the first region affected by a solar storm.
According to the researchers, as the constant flow of charged particles in the solar wind streams past Earth, it causes the foreshock to emit simple waves that can be likened to a low, single musical note.
When a solar storm passes by Earth, however, the impact of it hitting the magnetic field's foreshock causes that 'music' to rise in pitch and become far more complex.
"It's like the storm is changing the tuning of the foreshock," Lucile Turc, a space physicist at the University of Helsinki and lead researcher of this new paper, said in an ESA press release.
This simulation, produced by the Vlasiator computer model developed at the University of Helsinki, shows the complex waves produced between the foreshock and bow shock of Earth's magnetic field during a solar storm.
Credit: Vlasiator team, University of Helsinki
As shown in the image above, as a solar storm impacts (from the right), waves produced by the foreshock propogate in a complex pattern downwards (to the left) until they hit the bow shock.
According to the ESA:
"The collision of the magnetic waves modifies the behavior of the bow shock, possibly changing the way it processes the energy of the incoming solar storm. Behind the bow shock, the magnetic fields of Earth start to resonate at the frequency of the waves and this contributes to the transmission of the magnetic disturbance all the way to the ground. It is a fast process, taking around 10 minutes from the wave being generated at the foreshock to its energy reaching the ground."
Magnetic disturbances from the solar wind and solar storms manifest as a type of space weather known as a geomagnetic storm.
Geomagnetic storms often result in displays of auroras - the northern and southern lights - as solar particles become trapped along the magnetic field lines, and stream down into the upper atmosphere near the poles. While these are spectacular to behold, there can also be negative impacts from strong geomagnetic storms, such as power blackouts.
With this research adding to our knowledge of space weather, it may provide more clues that could help us avoid the worse impacts of geomagnetic storms, and possibly make better predictions of their effects.
As we wait in anticipation for future life-seeking missions to Mars, asteroids and other space bodies in our solar system, speculation that these probes will find life forms is increasing, but most scientists agree that it will be bacteria or other microorganisms. One who doesn’t is leading British space scientist Professor Monica Grady.
“If there is something on Mars, it’s likely to be very small—bacteria. But I think we’ve got a better chance of having slightly higher forms of life on Europa, perhaps similar to the intelligence of an octopus.”
In a recent speech at Liverpool Hope University (covered by Phys.org), her first as the school’s new Chancellor, Grady explained that she’s confident Europa is home to higher-level life forms, but they’re in lower-level realms than on the surface. It’s slightly smaller than Earth’s moon but covered with a 15-mile thick layer of ice. That ice would protect creatures living underneath it from deadly solar radiation and asteroids – Europa’s atmosphere is too thin to protect it or support life. On the other hand, it’s likely that underneath all of the ice is liquid water of the salty kind, and hydrothermal vents that could spark the creation of life and then provide an environment to support it. If this sounds like Earth, Grady agrees.
“”But I think it’s highly likely there will be life elsewhere—and I think it’s highly likely they’ll be made of the same elements. Humans evolved from little furry mammals that got the opportunity to evolve because the dinosaurs were killed by an asteroid impact. That is probably not going to happen on every planet—but it’s at least possible based purely on a statistical argument.”
But octopuses?
“I’m fairly specified we’re all there is at our amount of intelligence in this planetary method. And even if there are octopuses on Europa, that does not give us a cause to damage our planet.”
Europa
Describing the chances for finding intelligent life at our level (we can debate the notion that we’re not so intelligent at another time) in the Milky Way as highly unlikely, Grady sees us as galactic environmentalists – protecting both our planet and any space body we set foot or probe on. Her choice of “octopus” to describe the highest level of life we might encounter may just be a backhanded reference to the movie ‘Europa Report’ in which the first mission to Europa discovers a tentacled, bioluminescent creature described as a cross between an octopus and a squid. On the other hand, many people believe that the mammal-like intelligence of octopuses is because they’re aliens on Earth. Could they be from Europa?
We’ll have to wait for the anticipated Jupiter Icy Moon Explorer, Europa Clipper or Europa Lander missions to find out.
Or, we could figure out a way to talk to an octopus.

1KM Long UFO Seen Over Mountain Range Heading Towards Nellis AFB, Video, UFO Sighting News.
1KM Long UFO Seen Over Mountain Range Heading Towards Nellis AFB, Video, UFO Sighting News.
Date of sighting: January 29, 2020
Location of sighting: 45 Miles From Baker, Nevada
This video was taken on the extraterrestrial highway. An area famous for its UFO sightings in the middle of nowhere. This video is an awesome capture of an actual alien craft in the Nevada area. This object is 40 miles from Baker city and 132 miles from Las Vegas, Nevada...which is easy to find out by looking at the road sign at the 14 second mark in the video. Las Vegas has Nellis AFB which has given some land behind the old firing range to the Tall White Species, in exchange for friendship and technology. But this is also not far from Area 51. This UFO is about 1km across using the mountains to determine its size. Thats a mothership...and its following the mountain range...and guess what? The mountain range leads directly to behind Nellis AFB...the Tall White location. This is 100% proof that alien activity is still happening in Nevada. I love the detail on this one. It has an open payload door area at its top, lower center has a white shiny half dome...classic disk shape.
Commercial pilot César Murillo Pérez, who flies for Colombian airline company Viva Air, recorded a video of what appears to be a metallic, roughly spherical object while in the air over Medellín, the capital of Colombia’s Antioquia province. He immediately posted the video to Tiktok site and it began to go viral with over 820,000 views. The object is clearly not a balloon since its sides are not round but actually more cube with protruding edges. This UFO looks very similar to the UFO that was released by accident by the government in infrared. Also the person really is a pilot who has posted other videos of aircraft, and sunsets above places around the globe. He flies from South America to Europe. This is absolutly a UFO and its the most legitimate and close up focused view of a UFO of 2020 so far. Scott C. Waring
