Two F-14 fighter jets chased a large triangular UFO and disappeared, Puerto Rico, December 28, 1988

On December 28, 1988, at approximately 7:45 pm, a large triangle craft roughly the size of a baseball field was seen moving steadily along in the region near the naval air station in Puerto Rico, according to many witnesses (over a hundred). Three F-14s intercepted the moving UFO and apparently tried to force it to change its course.

As the navy fighter planes engaged the large craft, it slowed down its forward speed almost to a standstill. One plane, in particular, stayed mostly to the right of the UFO and another stayed behind the UFO making close approaches at times. The third plane apparently stayed a bit farther out. The F-14 in the rear came close to the object, but as it flew either over or under the object, it was not seen again. Small red lights were also seen at times flying outside the large craft and may have served to protect the craft. It was as if the fighter plane had somehow been drawn into the large craft. The second aircraft made a sweep closer to the large object and was seen by one ground witness—using binoculars—to suddenly disappear—possibly being taken in by the UFO. The third F-14 reportedly high-tailed it out of the area on afterburner with glowing red lights chasing after it apparently in pursuit, according to ground witnesses.

James Webb ST just captured massive clouds on an Alien Planet in unprecedented detail

A weird alien world cloaked in clouds of sand-like silicate granules has been discovered by the James Webb Space Telescope.

The exoplanet finding, revealed in a recent paper as the first of its kind, was made by the NIRSpec and MIRI instruments on the James Webb Space Telescope. Astronomers discovered indications of silicate-rich clouds surrounding a brown dwarf roughly 20 times the size of Jupiter in the data. The discovery backs up several previous speculations concerning these strange planet-like planets.

Brown dwarfs are weird objects that are not quite large enough to ignite into stars but are also not small enough to be considered planets. Brown dwarfs, while unable to consume normal hydrogen, can generate their own light and heat by burning deuterium (a less common isotope of hydrogen that contains an extra neutron).

VHS 1256 b is a brown dwarf that orbits two tiny red dwarf stars 72 light-years from Earth in the constellation Corvus, or the Crow, in the southern sky. Astronomers spotted the odd exoplanet in 2016, and its reddish glow has perplexed them ever since. They suspected that the glow was created by some kind of atmosphere. According to Forbes, observations from the James Webb Space Telescope have now corroborated those predictions, demonstrating that VHS 1256 b must be surrounded in dense clouds filled of sand-like silicate grains.

Water, methane, carbon monoxide, carbon dioxide, sodium, and potassium were also found in the atmosphere of VHS 1256 b by Webb.

"We will know more from iterations on the data reduction," said Brittany Miles, an astronomer at the University of California, Irvine and the project's principal researcher, in an email to Space.com. "So far, it appears to be pretty close to theoretical expectations."

The Webb data were so thorough that they revealed that the ratio of the various gases changes throughout the atmosphere of VHS 1256 b, implying that the atmosphere is not static, but rather chaotic and turbulent.

"There is an expected ratio of, example, methane and carbon monoxide in a tranquil atmosphere," Sasha Hinkley, an astronomer at the University of Exeter in the United Kingdom and one of the study's co-authors, told Forbes (opens in new tab). "However, we're finding that this ratio is significantly skewed in many planetary atmospheres, implying that there is turbulent vertical mixing in these atmospheres, dredging up carbon dioxide from deep down to mix with methane higher up in the atmosphere."

VHS 1256 b is small for a brown dwarf, suggesting that the body is young. The exoplanet orbits its two parent stars 360 sun-Earth distances apart in an oval-shaped orbit that takes 17,000 years to complete.

“One of a Kind” Massive Triple Star System Detected

Earlier this year, researchers revealed the discovery of an extraordinarily compact “one-of-a-kind” system of three stars. A partnership between two young researchers at the Niels Bohr Institute at the University of Copenhagen is currently focusing on how this unusual combination of a binary set of stars and a revolving larger star can form.

Tertiary star formation on a massive scale

The star system is made up of a binary set of stars, two stars that orbit each other, and one more massive star that orbits the binary.

“As far as we know, it is the first of its kind ever detected”, Alejandro Vigna-Gomez says. “We know of many tertiary star systems (three star systems), but they are typically significantly less massive. The massive stars in this triple are very close together – it is a compact system. The orbital period of the binary (~1 d) is the same as that of the rotation of Earth (1 day). The combined mass of the two of them is twelve times the mass of our Sun – so rather big stars. The tertiary star is approximately 16 times the mass of our Sun, so even bigger! The inner orbit is circular in shape with close to six revolutions of the tertiary star around the binary per year. Pretty fast, when you consider the size of them – unsurprisingly, the system is very luminous, so at first they were detected as a stellar binary”.

The dedication of amateurs led to the discovery of the star system

The initial discovery of the unusual nature of this highly peculiar system was equally remarkable in that it was discovered by amateur astronomers.

A group of amateur astronomers who were combing through a public data set from NASA’s TESS observatory (Transiting Exoplanet Survey Satellite) discovered something unusual.

The level of professionalism can be quite high among amateurs, and they made the professional astronomers aware of anomalies in the detection. It was discovered that what had previously been thought to be two stars were really three. These kinds of communities are known as citizen scientists.

The combination of expertise in dynamics and stellar evolution proved to be fruitful

Postdoc Alejandro Vigna-Gomez explains that when investigating the formation of the star system, several options were considered.

• If, for instance, the bigger star formed first, it would likely have ejected material that would have disrupted the formation of a binary that close.
• Another possibility is that the binary and the third star formed separately from each other and eventually encountered and locked in their orbits because of gravity.
• – or a third possibility, where two binaries formed and one merged into one, bigger star.

This is where the combined efforts of Bin Liu, an expert on dynamics, and Alejandro Vigna-Gomez’s knowledge of star formation came in handy. They coded the options and ran more than 100.000 iterations on the computer, in order to assess the most likely outcome of this scenario.

The result turned out to be in favor of the two binary systems forming initially and one of them merging with one star. Their results show that the two binary scenario could in fact explain the origin of the triple system.

The way forward requires the expertise of an astronomer specializing in observations

“Now we have a model of the most likely scenario on this unique system. But a model is not enough. And there are two ways in which we can prove or disentangle our theory on this formation”, postdoc Alejandro explains. ”One is studying the system in detail and the other is to make statistical analysis on a population of stars. If we go into the system in detail, we shall have to rely on the expertise of an astronomer. We already have some preliminary observations, but we still need to go through the data, and make sure we are interpreting it well”.Bin Liu continues: “We also encourage people in the scientific community to look at the data deeply”, Postdoc Bin Liu says. “Maybe there are more compact systems buried in the data. What we really want to know is whether this kind of system is common in our universe”.Alejandro Vigna-Gomez and Bin Liu have now mapped ut quite a lot of work for themselves. “We need to find an adequate telescope with available observing time somewhere in the world and talk to someone who is really an expert from the observational point of view. The data from telescopes needs to be understood correctly. What you see in a telescope is not entirely what you get, so to say. It must be interpreted”.

So more collaboration is underway, very much in the spirit of Niels Bohr, Alejandro says:

“A Chinese and a Mexican with each their different fields, dynamics, and star formation, meet at the Niels Bohr Institute and are now on the way to yet more scientific collaboration”.

Caught in the Webb! NASA’s James Webb Space Telescope captures a stunning photograph of thousands of never-before-seen young stars in the Tarantula Nebula, 161,000 light-years away from Earth

• NASA's James Webb Space Telescope has captured a stunning look at the Tarantula Nebula 
• The stellar nursery, officially known as 30 Doradus, sits 161,000 light-years away in the Large Megallanic Cloud galaxy 
• 'Take a moment to stare into thousands of never-before-seen young stars in the Tarantula Nebula,' NASA said. [The James Webb] reveals details of the structure and composition of the nebula.'

By CHRISTOPHER CARBONE U.S. SCIENCE AND TECHNOLOGY EDITOR FOR DAILYMAIL.COM

NASA's James Webb Space Telescope captured thousands of never-before-seen young stars in a spider-shaped stellar nursery known as the Tarantula Nebula.

The cosmic nursery is officially called 30 Doradus and is located 161,000 light-years away in the Large Megallanic Cloud galaxy, which happens to be the biggest and brightest star-forming region in the Local Group - the galaxies closest to our Milky Way.

'Take a moment to stare into thousands of never-before-seen young stars in the Tarantula Nebula,' NASA shared on Twitter. [The James Webb] reveals details of the structure and composition of the nebula, as well as background galaxies.'

'The Tarantula Nebula gets its name from its dusty filaments. The largest and brightest star-forming region near our galaxy, it's home to the hottest, most massive stars known!' the space agency said.

'Take a moment to stare into thousands of never-before-seen young stars in the Tarantula Nebula,' NASA shared on Twitter. [The James Webb] reveals details of the structure and composition of the nebula, as well as background galaxies.' The stellar nursery is officially called 30 Doradus - but is known as the Tarantula Nebula - and is located 161,000 light-years away in the Large Megallanic Cloud galaxy

This nebula gives us information about what star formation might have looked like at its peak in our cosmic history. 

Viewed with Webb’s Near-Infrared Camera (NIRCam), the region resembles a burrowing tarantula’s home, lined with its silk. The nebula’s cavity centered in the NIRCam image appears to be hollowed out by blistering radiation from a cluster of massive young stars, which sparkle pale blue in the image.

Only the densest surrounding areas of the nebula can resist erosion by these stars’ powerful stellar winds, forming pillars that appear to point back toward the cluster. These pillars contain forming protostars, or very young stars, which will eventually emerge from their dusty cocoons and take their turn shaping the nebula.

The Tarantula Nebula has been fascinating astronomers for years because it has a similar type of chemical composition as the huge star-forming regions seen in the universe's so-called 'cosmic noon' - meaning when the cosmos was only a few billion years old and such star formation was at a peak. 

The cosmic region takes on a different appearance when viewed in the longer infrared wavelengths detected by Webb’s Mid-Infrared Instrument (MIRI). In this image (above), the hot stars fade and the cooler gas and dust seem to glow. Embedded within the stellar nursery clouds are protostars that are still gaining mass. The shorter wavelengths of life absorbed or scattered by dust grains in the nebula - and don't reach Webb to be detected

Star-forming regions in the Milky Way don't have the same chemical composition and are not producing at that same super-fast rate as the Tarantula Nebula. 

The cosmic region takes on a different appearance when viewed in the longer infrared wavelengths detected by Webb’s Mid-Infrared Instrument (MIRI).

In this image, the hot stars fade and the cooler gas and dust seem to glow.   

Embedded within the stellar nursery clouds are protostars that are still gaining mass. The shorter wavelengths of life absorbed or scattered by dust grains in the nebula - and don't reach Webb to be detected - while the longer mid-infrared wavelengths penetrate that dust and reveal details that scientists may not have seen before. 

'Despite humanity’s thousands of years of stargazing, the star-formation process still holds many mysteries – many of them due to our previous inability to get crisp images of what was happening behind the thick clouds of stellar nurseries,' NASA shared in a statement.

Just a few days ago, the James Webb captured its first image on an exoplanet located just 385 light-years from Earth, showing incredible details never seen by human eyes. 

The exoplanet known as HIP 65426 is just 15 to 20 million years old, which is much younger to our 4.5-billion-year-old Earth. 

The telescope used its Near-Infrared Camera (NIRCam) and Mid-InfraRed Instrument (MIRI) that can block out surrounding starlight to snap epic images of the exoplanet HIP 65426.

The alien world was first discovered in 2017 by the European Southern Observatory's Very Large Telescope, in Chile, but the long wavelengths were blocked by Earth's atmosphere.

However, since Webb is soaring through space, it was able to take direct shots of the planet that astronomers can process to remove the starlight and uncover the planet. 

NASA said it is a gas giant that is without a rocky surface and therefore could not host life. 

'But Webb's first capture of an exoplanet already hints at future possibilities for studying distant worlds, NASA shared in a statement. 

NASA's James Webb Telescope captured detailed images of its first exoplanet that sits outside of our solar system. The telescope used its powerful technologies to 'see' the exoplanets longer wavelengths that are missed by Earth-based telescopes. The exoplanet is just 15 to 20 million years old, which is much younger to our 4.5-billion-year-old Earth

The James Webb Telescope: NASA's $10 billion telescope is designed to detect light from the earliest stars and galaxies

The James Webb telescope has been described as a 'time machine' that could help unravel the secrets of our universe.

The telescope will be used to look back to the first galaxies born in the early universe more than 13.5 billion years ago, and observe the sources of stars, exoplanets, and even the moons and planets of our solar system.

The vast telescope, which has already cost more than $7 billion (£5 billion), is considered a successor to the orbiting Hubble Space Telescope

The James Webb Telescope and most of its instruments have an operating temperature of roughly 40 Kelvin – about minus 387 Fahrenheit (minus 233 Celsius).

It is the world's biggest and most powerful orbital space telescope, capable of peering back 100-200 million years after the Big Bang.

The orbiting infrared observatory is designed to be about 100 times more powerful than its predecessor, the Hubble Space Telescope.

NASA likes to think of James Webb as a successor to Hubble rather than a replacement, as the two will work in tandem for a while. 

The Hubble telescope was launched on April 24, 1990, via the space shuttle Discovery from Kennedy Space Centre in Florida.

It circles the Earth at a speed of about 17,000mph (27,300kph) in low Earth orbit at about 340 miles in altitude.

A footage out of England shows what appears to be a perfectly cube-shaped cloud hovering in the sky. 

The rare sky phenomenon was captured earlier this week by Megan Coombs during a visit to a National Trust site in Surrey with the appropriately spooky name 'Devil's Punch Bowl.' 

Megan said that "there is something mega suspicious" about the box-like cloud in the sky that seems to have one of its sides illuminated by the sun, reports CoasttoCoast. 

It is not the first time square or rectangular clouds have been observed. It looks like these clouds are formed as a result of geoengineering/weather modification.

5 UFOs flying over Hamilton, New Zealand 2022

This UFO sighting was filmed over Hamilton in New Zealand ion 18th March 2022 but it was just recently submitted to MUFON.

Witness report: 

While my partner and I were in our lounge watching a UFO documentary, my partner had some sort of sudden inclination to look out the window, perhaps as a result of the doco we were watching.
She saw glowing lights tracing a path across the sky.
Initially we only saw 3, but then 2 more started catching up to the first 3 from beyond the horizon to the southwest.
The 5 amber glowing lights seemed to speed up and slow down as they traced a path across the sky.
Perhaps with the exact time info off the video, you will be able to more easily confirm the air traffic from that date and time.
We live in a city where it is common for hot air balloons to fly at night as part of a local festival, which had concluded around that time, but they do not fly as high as what we saw, the colouring of the light seemed too bright, large and consistently visible to be the occasional flame of a hot air balloon. I could also find no report or event listing of any flying at night. Hot air balloons do not have the flight control capabilities we saw:
The lights seemed to speed up and slow down in relationship to eachother to move as a group, as well as at least one of them changing its flight direction to circle back for the others.
From visual comparisons I first thought it might have been starlink satellites, but these seemed too low, the wrong colour, and too oddly spaced. Also starlink satellites would not stop or reverse course in the sky I presume.
I got my cellphone and filmed the lights for 4 minutes exactly, and stopped filming as they started to fade once they had flown over us. It looked as though they became obscured by cloud cover that was impossible for us to see against the night sky, as they seemed to just disappear of their own accord.
After that we went inside to try and find out whether we could explain what we saw through conventional means, but did not manage to, regardless we presumed that we had simply seen something with a mundane explanation and mostly moved on and forgot about it. The more time goes on the more I keep coming back to the fact that I never managed to successfully explain what it was.
This is not the first time my partner has suddenly felt compelled to look out a window and immediately sees an amber light moving strangely in the sky. Last time she did so in the early hours of the morning and woke up suddenly, instantly knowing specifically that there was a “UFO” in the sky for her to look at, but that night for whatever reason we both didn’t feel compelled to get a phone and film it.

Supermassive black hole 12 billion Times more Enormous than our Sun Discovered

Astrophysicists have found an out-of-place supermassive black hole -- 12 billion times more enormous than the sun -- that mysteriously formed when the cosmos was less than 900 million years old.

Such behemoths are usually found in the more modern cosmos, which seemingly offers more feeding material. Black holes are areas of space so condensed with matter that not even photons of light can discharge their gravitational fists. They are sensed as they pull and eat neighbouring stars and dust, making a cosmic zoo of noticeable phenomenon, such gas jets and rapidly spinning accretion disks.

“Before this finding the most enormous black hole identified within 1 billion years after the Big Bang was about 5 billion solar mass, less than half the mass of the new discovery,” Bram Venemans, research staff researcher with Max Planck Institute for Astronomy in Germany, wrote in an email to Discovery News.
The finding, reported in this week’s Nature, offers a serious challenge to theories about how black holes grew in the early cosmos.

Researchers previously expected young black holes started off with between 100 and 100,000 times the mass of the sun and matured from there by consuming in intergalactic matter and/or merging with other black holes.

It may need either very extraordinary ways to grow the black hole within a very short time, or the presence of a huge seed black hole when the first generation of stars and galaxies formed,” lead scientist Xue-Bing Wu, with China’s Peking University in Beijing, said in an email to Discovery News.

Neither clarification fits with present theories. “A very stimulating feature of this work is that the outcomes hint that in the early cosmos the supermassive black holes and their host galaxies did not co-evolve,” said astrophysicist Akos Bogdan, with the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., who was not involved in the study.
It is improbable the black hole’s parent galaxy would be as big as what calculations based on existing theories would conclude. “This would propose that -- at least in this case -- the black hole is developing faster than the galaxy, questioning the often expected co-evolution of galaxies and their central black holes through cosmic time,” added Venemans. The newly discovered black hole exists in in an enormously bright quasar that existed when the cosmos was about 857 million years old – about 6% of the cosmos’s current 13.8-billion-year age.

“We can comparatively easily sense this object because it is brighter than others at the same distance,” Wu said.
Observations with numerous ground- and space-based telescopes carry on, as well as a search for any comparable giant siblings.

“These objects are so far away from us so most of them look (very) faint even if their inherent brightness is large,” Wu said.

Planet Nine may be responsible for tilting the Sun

How our possible rogue planet may be messing with our solar system

Earlier this year an announcement raised a tantalizing possibility: a ninth planet lurking in the outer reaches of our solar system. The announcement turned the astronomy and planetary science world upside down.

Caltech astronomer Michael Brown and theoretical astrophysicist Konstantin Batygin found evidence for a possible 10 Earth mass planet that may be tilting long-orbiting dwarf planets on their sides and shepherding them into clusters far past the orbit of Neptune in highly eccentric orbits. In the last several months, more and more papers have been published about the possible planet and how it might prove an explanation for other strange things happening in our solar system.

At a press conference held this afternoon, at the AAS Division of Planetary Sciences annual meeting in Pasadena Ca, another announcement was made about Planet Nine’s effects on the spin-axis tilt of our Sun. This time, the paper titled Solar Obliquity Induced by Planet Nine is lead by Caltech graduate student Elizabeth Bailey, with Brown and Batygin as co-authors.

We’ve known that the Sun is tilted for about 200 years, but scientists have never known why. Only the catch here is, the Sun isn’t actually tilted at all. We are. To explain this oddity and what’s happening to our solar system we spoke with co-author and theoretical astrophysicist, Konstantin Batygin.

Astronomy Magazine: What’s happening with the alignment in our solar system?

Konstantin Batygin: When planetary systems form, they form from very flat discs.  The motion that everything in our entire planetary system forms in a very proto planetary flat disc is one of the basic principles of planetary formation theory. The planetary orbits themselves are fully consistent- If you look at how inclined the planets are with respect to each other they are only inclined by no more than one degree so the planets of the solar system are remarkably flat.

AM: What about the Sun?

KB: The Sun’s rotation was measured for the first time in 1850 and something that was recognized right away as that its spin axis, its north pole, is tilted with respect to the rest of the planets by 6 degrees. So even though 6 degrees isn’t much, it is a big number compared to the mutual planet-planet misalignments. So the Sun is basically an outlier within the solar system. This is a long-standing issue and one that is recognized but people don’t really talk much about it. Everything in the solar system rotates roughly on the same plane except for the most massive object, the Sun which is kind of a big deal.

Hypothetical Planet 9, and 9 related eTNOs

WikiMedia Commons

AM: Why is there this misalignment between the Sun and the orbits of the planets?

KB: We asked ourselves, “what obliquity, what misalignment would Planet Nine induce in the solar system?” because it must induce some. We know that Planet Nine’s orbit in inclined. As a result, when Planet Nine torques the rest of the solar system, the two sort of act as two precessing tops. Planet Nine being in its own plane induced a precession on the remainder of the solar system as if the plane of the solar system was a flat top on the surface of a table.

AM: So Planet Nine’s gravitational influence is forcing the solar system to wobble?

KB: If you imagine that the Sun and the planets were co-planar, meaning they were locked into the same plane 4 billion years ago, and allow the clock to run forward in the presence of Planet Nine, then 4 billion years later the Sun would have been apparently tilted by exactly it’s current obliquity, or 6 degrees. But what’s actually going on is that the Sun is staying put in its fixed reference frame and it’s the planetary orbits that are being tilted by Planet Nine. So Planet Nine has tilted the entire disk of the solar system by 6 degrees and because we live on that disc … to us it looks like the Sun is tilted, but it’s actually the other way around.

AM: How could Planet Nine have that much influence on our entire solar system when it’s so far out?

KB: Here’s why: Planet Nine is only 10 Earth masses as compared to Jupiter’s 300 Earth masses, but its orbit is huge. So it’s an argument that is basically like an asymmetrical see-saw or a dolly. Planet Nine has a really long orbit so it can assert quite a bit of torque on the inner planets without having to apply so much force. Planet Nine has as much angular momentum as the entire solar system combined, because it’s orbit is so big.

AM: Have there been other theories about how this tilt may have happened before your theory of Planet Nine?

KB: I actually had theorized this in 2012 and wrote about it and the theory was almost exactly the same, except for it wasn’t Planet Nine doing the torqueing but a companion star. I theorized that a young star was bound to the Sun, and tilting the entire proto-planetary disc from which planets form. It’s believed that most stars are born binary but most of them lose their companions by the time they come out of the birth cluster.

AM: Does this help us better understand planet formation or solar system formation?

KB: It does help us understand planet formation because planet formation theory dictates that all things must start out co-planar, in the same plane. The fact that the Sun is tilted with respect to the rest of the solar system is almost a violation of that very fundamental principle, so understanding what’s going on there is important. But there’s also a second component to why this calculation is interesting. We very quickly realized that Planet Nine must do something, it must tilt the solar system by some angle and we thought to ourselves what if this angle was really big? What if the Sun was tilted by 40 degrees in our calculations? That would actually be evidence against Planet Nine, instead we got this beautiful agreement of the theory.

AM: Has this new data helped with your search for Planet Nine?

KB: What we’ve found is that the direction into which the Sun is tilted by Planet Nine is intimately related to the orbit of Planet Nine itself.  This is more or less a consistency check, it doesn’t help us or really provide too much new information but it gives us more confidence that we are actually barking up the right tree

Webb telescope wows with first image of an exoplanet

Astronomers see it as the start of a bonanza of studies exploring planets outside the Solar System.

The James Webb Space Telescope has taken its first picture of a planet beyond the Solar System — opening a window to understanding other worlds and underscoring the telescope’s immense capabilities.

  Webb telescope spots CO2 on exoplanet for first time: what it means for finding alien life

The image is of a planet called HIP 65426 b, an object similar to Jupiter, but younger and hotter, that lies 107 parsecs from Earth in the constellation Centaurus. It is the first exoplanet image ever taken at deep infrared wavelengths, which allow astronomers to study the full range of a planet’s brightness and what it is made of.

“It gives us wavelengths we’ve never seen planets at before,” says Beth Biller, an astronomer at the University of Edinburgh, UK, and a member of the discovery team. The image was reported in a paper on the arXiv preprint server on 31 August¹; the report has not been peer reviewed.

The finding confirms how powerful Webb will be for studying exoplanets. Launched in December as a collaboration between NASA and the European and Canadian space agencies, the telescope began doing science in June, using its 6.5-metre-wide primary mirror to observe the Universe from a spot around 1.5 million kilometres from Earth. The fact that it was able to take such a sharp picture of HIP 65426 b suggests that it will be able to photograph even smaller planets, the size of Saturn or even Neptune, orbiting other stars. That would drastically improve scientific understanding of far-away planetary systems.

Astronomers know of more than 5,000 exoplanets, but they have taken pictures of only around 20. Imaging exoplanets directly is difficult, because they are often lost in the glare of the star around which they orbit.

But observing them at infrared wavelengths, as Webb does, helps to boost the contrast between star and planet. “You’re in the regime where planets are brightest and stars are dimmest,” says Aarynn Carter, an astronomer at the University of California, Santa Cruz, and lead author of the preprint.

‘Baby Jupiter’

Carter and his colleagues chose to study HIP 65426 b after other astronomers discovered it in 2017² using the European Southern Observatory’s Very Large Telescope in Chile. In July this year, Carter’s team used instruments on Webb to physically block the light from HIP 65426 b’s star, allowing the planet to pop into view. HIP 65426 b orbits its star at roughly twice the distance that Pluto orbits the Sun.

Unlocking the additional infrared wavelengths allowed the astronomers to better understand how much energy the planet’s atmosphere radiates. That, in turn, allowed them to use models of stellar evolution to pin down its mass to 7 times, and its radius to 1.45 times, that of Jupiter.

  Four revelations from the Webb telescope about distant galaxies

HIP 65426 b is probably around 14 million years old, making it “a baby Jupiter”, Biller says. It’s “like Jupiter, but right after it formed”. Our Solar System is around 4.5 billion years old.

Future studies will probably probe how HIP 65426 b formed and evolved over time. Meanwhile, other astronomers are planning to use Webb to study many other exoplanets, especially big ones that lie relatively far from their host star and can thus be imaged directly.

Such work complements other ways in which Webb can observe exoplanets, such as analysing the starlight passing through a planet’s atmosphere to see what chemical compounds the atmosphere contains. Astronomers can’t use that technique on HIP 65426 b, because it lies too far away from its star. But Carter’s team is applying spectral analysis to a different planet, which is substantially larger than Jupiter and is known as VHS 1256 b. It lies 22 parsecs away from Earth in the constellation Corvus.

The findings of that analysis were reported on arXiv on 1 September³, and include signs of silicate grains — essentially, hot sand — in the atmosphere of VHS 1256 b. “That’s a hugely exciting result,” Carter says. It is the first time that sandy grains have been spotted in the atmosphere of a planet beyond the Solar System.

Such sand clouds can form when temperatures on the planet are hot enough to vaporize rock-forming minerals.

Even Short Flights to Space Cause Cell Mutations That Could Lead to Cancer and Heart Disease

Spaceflight can be dangerous – and not just because astronauts are strapped to an ongoing massive explosion for their ascent into orbit. Its long-term effects on the human body are starting to come more clearly into focus, and so far, none of the answers have been good. Now a new study from Mount Sinai Medical Hospital has found that, even on relatively short duration spaceflights, astronauts suffer potentially damaging DNS mutations.

The study, published in the August edition of Nature Communications Biology, was conducted on 14 astronauts that flew on shuttle flights from 1998 to 2001. These astronauts, the overwhelming majority of whom were men, with an average age of 42, had their blood drawn before their shuttle flights and then again right after. Scientists have used these blood samples for the last twenty years, and this new study utilizes them and the dramatically improved DNA sequencing technology that the previous two decades have brought us.

What the researchers found in these old blood samples are known as somatic mutations in the hematopoietic system, where blood cells are formed. Somatic mutations are mutations that happen to a person during their life, but don’t affect their egg or sperm cells, meaning they won’t be passed on to the next generation. In this particular instance, the mutations they found were associated with a disorder called clonal hematopoiesis (CH), where more blood cells come from one specific clone.

That isn’t necessarily cause for immediate alarm – in fact, CH doesn’t usually have symptoms associated with it. However, it indicates an increased risk factor for cardiovascular disease and blood cancer. And the somatic mutations the researchers found in the astronaut’s DNA were similar to those caused by ultraviolet radiation or specific chemicals.

Even more concerning, the most frequently changed gene was one responsible for producing a tumor-suppressing protein and is commonly associated with acute myeloid leukemia. However, even this change was below a standard threshold that doctors use to actually diagnose someone with CH.

However, these astronauts were only in space for an average of 12 days. Longer missions, such as those to Mars or even a permanent based on the Moon, could lead to much more damaging effects that have yet to be studied. There have already been plenty of studies of Mark and Scott Kelly, two twin astronauts who acted as a controlled pair to study microgravity and spaceflight’s effects on the human body. The effects do not appear to be good.

And the CH gene change wasn’t the only problem found in the shuttle astronauts either. There was a surprisingly high amount of mitochondrial DNA floating in their bloodstreams, which can lead to inflammation problems. All of these issues point to the difficulty of the human body in dealing with spaceflight. None so far are red flags, but they certainly seem worth keeping an eye on while we restart our human exploration of the solar system.

During a recent spacewalk Russian cosmonauts Commander Oleg Artemyev and Flight Engineer Denis Matveev exit the ISS to continue outfitting the European robotic arm on the station's Nauka laboratory when suddenly an unknown object comes into view next to the service module solar battery. 

The MCC (control center) who monitors the spacewalk through a live cam noticed the object upon the operator ask Oleg Artemyev to see and describe the object but Oleg said that she did not understand what the operator was asking her, so he ordered Oleg to continue to work on the European robotic arm. 

It seems impossible that the astronaut did not see the UFO, but it could be that the astronaut not wanted to talk about the UFO which came very close the ISS since they are not allowed to talk about UFO encounters in space. 

Remarkably, the camera continues to track the object until it disappears from view, proving that this is not space debris, but an extraordinary object under intelligent control, unknown to the space agencies. 

The UFO incident (and conversation) can be seen from 7.22.55 to 7.27.55 minutes in the following live video. (Click CC video for English translation).

With the sun active and the climate changing the temperatures, we will be seeing many weather events that will be hard to understand or explain. 

As the world changes and shows us new things...Watch with an open mind. Cylinder shaped tubes of maybe ice are falling from the sky and it's not raining, but could be large hail? This week we have some freak accidents with large hail hitting people...this can kill you. 

Could these objects be part of a weather modification (geoengineering) program? Like cloud seeding which is a type of weather modification that aims to change the amount or type of precipitation that falls from clouds by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud. 

Whether these cylindrical objects (Ice or... something else?) are the result of cloud seeding or not, it definitely looks manufactured and I've never seen this before.

The video shows many cylindrical objects falling from the sky and 'Bruce sees all' simply wanted to share it with you. Every object has another object following it and all of them all the same shape.

JP, who currently serves with the US Army as a quartermaster and chemical repairer, was recently taken on a covert mission to an underwater city off the Florida coast in the Bermuda triangle region. 

He said that he witnessed tall human looking beings that inhabited the city which was protected by a giant underwater dome. He said that there were two other domed cities adjacent to the one he visited. 

He also said that he was there with a small contingent of soldiers to protect a civilian negotiator who met with leaders of the underwater city to conduct negotiations. 

In this Exopolitics Today interview, JP discusses his mission, the people involved, and what he witnessed at the bottom of the ocean in the Bermuda triangle region.
