Book of Enoch: manuscript would reveal that angels were aliens
Book of Enoch: manuscript would reveal that angels were aliens
The debate about angels continues; While religions maintain that they were the closest beings to God , there is more and more evidence that could show that they were extraterrestrial beings or the ancient astronauts who visited us in the past.
Many people have wondered in recent years what are angels or why some “fell” to Earth? According to ancient scriptures, the fallen angels defied God .
They committed different sins like lust, in addition to doing everything that was forbidden to them. They maintained relationships with humans , in addition they taught him different knowledge that was destined to be only theirs.
If we analyze these words, we could say that the evolution of human beings depended directly on the interaction of “angels”, an almost identical resemblance to the theories of the ancient astronauts and their intervention in humanity.
What are the fallen angels?
According to the Bible , the fallen angels are those who turned away from God , questioning him. This led to their being banished from heaven and many of them were sent to hell.
Since the translations of ancient texts in 1800, which were discovered in Ethiopia in 1768, the Book of Enoch is the main source to know more about these beings who came to Earth from the skies.
However, just as it has served religion for its theological studies, it has also served academics to strengthen theories related to extraterrestrials .
Several copies were discovered in 1948 among the Dead Sea scrolls. This has led us to think that we may be able to trace accounts that bear a great deal of resemblance to ancient Sumerian stories .
In fact, in the book of Enoch you can read about the origin of the giants , mostly known as the Nephilim and how they represented a hybrid race that was born as a result of the relationship between humans and these “angels”.
The development of humanity since the appearance of the “angels”
In addition to their strange arrival from the heavens, similar to the arrival of the Sumerian “gods” or other cultures and who are responsible for the birth of a hybrid race , such as the Nephilim, the angels, according to the book of Enoch, they are directly responsible for humanity’s beginning its evolution .
It details how it was they who taught humanity to work metal , being able to make swords, knives, shields, armor. They also learned to use “magic medicine” , to cut the roots to heal, astrology , specific knowledge about our Solar System, the passage of the stars and the path of the Sun and the Moon.
An extract from the ancient texts reads as follows:
And Azazel taught men to make swords and knives, and shields, and breastplates, and made known to them the metals of the Earth and the art of working bracelets, and ornaments, and the use of antimony, and the beautification of the eyelids, and all kinds of precious stones, and all coloring tinctures. And there was much wickedness, and they committed fornication, and they were led astray, and were corrupted in all their ways. Semjaza taught incantations and root cuts, Armaros the resolution of incantations, Baraqijal, taught astrology, Kôkabêl the constellations, Ezeqeel the knowledge of the clouds, Araqiel the signs of the Earth, Shamsiel the signs of the sun, and Sariel the course of the moon ”.
Angels Ancient astronauts
More and more people are sure that the ancient stories that refer to angels really speak of aliens. The descriptions, their way of acting.
All the characteristics related to the beings of other worlds fit perfectly with the description, not only of the angels, but of the ancient gods of all ancient religions.
According to Erich von Däniken , there are certain artifacts and constructions that reveal the level of intelligence and technology that these beings possessed, which helped humanity to develop; An example of these are the same pyramids in Egypt or monuments such as Puma Punku in Bolivia.
The academic also maintains that all the ancient art and iconography found in the ruins around the world, show a story almost identical to that read in the Bible, only that in it you can see graphic illustrations of flying artifacts and technologically advanced.
The Bible also mentions great technologically advanced artifacts that, even today, would be impossible to replicate, such as the Ark of the Covenant ; .a The Bible speaks of that almost magical object that protected an entire people that traveled with it.
Von Däniken is sure that this device was an instrument that worked with radioactivity , which was so advanced that it could transform organic matter into a food as valuable as manna.
An artifact that sparked wars and then mysteriously disappeared and that, to this day, still does not give any indication of its location.
Many religions are interpretations of older ones; the oldest accounts that the Bible give an almost literal explanation of how beings, of almost divine appearance, came down from the heavens and helped humanity to develop. Why not believe the story of the angels refers to these same beings? Religion has been in charge of eliminating this thought from its faithful, but not in the critical mind.
A meteorite that lit up the night sky in the US Midwest in 2018 contains ‘pristine’ organic compounds that may offer clues to how life formed on Earth, according to researchers (via the Independent). It was spotted by motorists and others in several states after producing a fireball and loud explosion on January 18, 2018. Thanks to some quick thinking and action, the rocks were quickly in the hands of researchers before they could be contaminated.
Less than two days after it streaked across the sky, meteorite hunter Robert Ward found the first piece resting on the frozen surface of Strawberry Lake near Hamburg, Michigan. He was able to pinpoint the location by using NASA’s weather radar, as the meteorite chunks were similar in size to hail. He quickly got it to the Field Museum in Chicago, where curator Philipp Heck quickly set about studying it.
“This meteorite is special because it fell onto a frozen lake and was recovered quickly. It was very pristine. We could see the minerals weren't much altered and later found that it contained a rich inventory of extraterrestrial organic compounds,” Heck said in a statement. “These kinds of organic compounds were likely delivered to the early Earth by meteorites and might have contributed to the ingredients of life.”
The researchers determined that it was a rare H4 chondrite meteorite, representing only four percent of those found on Earth. The initial analysis determined that it contained over 2,600 separate organic compounds that were still intact despite the intense heat created when it blazed through the atmosphere. They also found that it likely broke off 12 million years ago from its parent asteroid, which formed 4.5 billion years earlier.
A lot of scientists were able to probe the rock using different techniques, “so we have an unusually comprehensive set of data for a single meteorite,” said Heck.
While the meteorite was as clean as one that lands on Earth can be, scientists are especially anxious to get their hands on a truly pristine specimen from the source — space. That’s scheduled to happen in 2023. when the NASA spacecraft Osiris-REx is set to return to Earth after it successfully grabbed and stowed a chunk of regolith from the asteroid Bennu.
My previous article was on the subject of how the Women in Black, the M.I.B., and the Black Eyed Children may have a medical condition not at all too dissimilar to albinism. Today, I’m going to share with you something else very strange about all three of those particular groups. It’s their undeniable ability to control our minds. I’ll start with the BEC. It was in the late 1990s when the phenomenon of theBlack Eyed Children first surfaced. It should be noted, though, that claims of earlier encounters have been made. For those who may not know, the BEC are described as young children – almost always around the ages of about ten to thirteen. They wear black hoodies. Their skin is pale. Their primary goal is to get inside the home of the targeted individual. And they almost always attempt to do so at night. I have 17 reports of BEC cases. They cover the period 2002 to 2019. In all of the reports I received, there was one very creepy angle to the activities of the BEC. It was that aforementioned issue of the BEC trying to get inside the home of the person in their sights.
Of course, most people would not even consider letting a few hoodie-wearing kids in late at night, and when darkness has fallen. The weird thing, however, is that people do let them in. I should stress that in most of the cases the BEC fail to get inside. In some incidents, though, they do manage to get inside. And that’s when things get really weird. The reason: those strange and sinister kids seem to have the ability to mind-control their victims. People recall – often in a hazy, dream-like state – letting them in, but having no understanding of precisely why they let them in. There are enough such incidents to make a good case that these kids are not what they appear to be. One man, who was extremely distressed by his encounter with two BEC in his home in San Antonio, Texas in November 2013, told me that he believed – by inviting them in – he had been forced into a kind of unholy “agreement” with the BEC. He even mused on the possibility that, in his own words, “…My soul was taken.” He had no real understanding of why he came to that conclusion. Only that he had entered into something akin to a Faustian pact that was out of his control.
Now, let’s have a look at one particular way in which a Women in Black took control of her victim back in the 1970s. Our story specifically goes back to October 23, 1971. The press said at the time: “A part-time housekeeper at President Nixon’s Key Biscayne retreat has testified she was put in a hypnotic daze by a stranger who told her to shoplift four dresses. Shirley Cromartie, 32, and a mother of three, pleaded no contest Thursday and was given a suspended sentence after law enforcement officers and a psychiatrist testified they believed she was telling the truth. Mrs. Cromartie holds a security clearance to work in the Florida White House, according to testimony. She said a woman met her in a parking lot and asked the time, then ordered her to take the items and bring them to her.” Like so many Women in Black, this one wore a long black wig and used mind-control abilities to enslave her target. John Keel, of The Mothman Prophecies, took a great deal of interest in this case, saying in his classic book that it all amounted to “not some small demonstration for the benefit of President Nixon.”
As for the Men in Black, there’s the matter of a certain UFO researcher/author: Trevor James Constable. In the early 1960s Constable said of the Albert Bender/M.I.B affair of the 1950s: “It is difficult indeed for me, as an occultist with some firsthand experience of this field of UFOs, to sort out Bender’s journeys back and forth across the threshold line between the physical and the astral. A biometric examination of Al Bender would probably indicate similar things to what it revealed about certain other researchers – total inability to distinguish between events on two planes of reality. Bender’s honesty I do not for a moment doubt. His discrimination I would deem non-existent. It seems almost incredible that the man could relate the full story of the construction of his chamber of horrors in the attic in the way Bender has. This is what convinces me of his honesty. Nothing could be more logical, in an occult way, than that the invisible entities he invited by the preparation of this locale, should indeed manifest to him, and thereafter proceed to obsess him for a protracted period, using hypnotic techniques that brought the man completely under their control [italics mine].”
Women warriors hunted and slaughtered big game in the Andes some 9,000 years ago, a burial site containing projectile points and butchery tools has revealed.
The remains of the 17–19 year old hunter and her artefacts were found in a grave at the high-altitude archaeological site of Wilamaya Patjxa, in what is today Peru.
She was found with tools including stone projectile points for felling large animals, a knife, and implements for gutting an animal and scraping or tanning hides.
It had long been assumed that — among early human hunter-gatherer societies — it was the men who did the former while the women undertook the latter task.
However, the find — along with an analysis of early burial practices more broadly — 'overturns the long-held "man-the-hunter" hypothesis', the US researchers said.
It is possible that nine millennia ago the hunters of Wilamaya Patjxa may have hunted vicuña — animals related to llamas and camels — which still roam the Andes today.
Women warriors hunted and slaughtered big game in the Andes some 9,000 years ago, as depicted, a burial site containing projectile points and butchery tools has revealed
'We believe that these findings are particularly timely in light of contemporary conversations surrounding gendered labour practices and inequality,' said paper author and anthropologist Randy Haas of the the University of California, Davis.
'Labour practices among recent hunter-gatherer societies are highly gendered, which might lead some to believe that sexist inequalities in things like pay or rank are somehow "natural" ', he commented.
'But it's now clear that sexual division of labour was fundamentally different — likely more equitable — in our species' deep hunter-gatherer past.'
Professor Haas and colleagues — with in collaboration with the local Mulla Fasiri community — discovered the warrior woman's burial, complete with its hunting 'toolkit' — during excavations at Wilamaya Patjxa back in 2018.
The researchers noted that the objects that accompanying people to their graves in death tend to also be those that they made use of in life.
The team determined that the hunter's remains were likely those of a woman based on the structure of the bones — a conclusion that was later validated by analysing the proteins found in samples of the individual's teeth.
Analysis of the woman's bones also found isotopic evidence of meat consumption, which the researchers said supports the conclusion that she was a hunter.
The team also found another hunter's burial site — this one occupied by the remains of a man — believed to be around 25–30 years of age.
'Our findings have made me rethink the most basic organizational structure of ancient hunter-gatherer groups,' Professor Haas said.
“Among historic and contemporary hunter-gatherers, it is almost always the case that males are the hunters and females are the gatherers.
'Because of this – and likely because of sexist assumptions about division of labour in western society – archaeological findings of females with hunting tools just didn't fit prevailing worldviews.'
'It took a strong case to help us recognize that the archaeological pattern indicated actual female hunting behaviour.'

It had long been assumed that — among early human hunter-gatherer societies — it was the men who did the former while the women undertook the latter task. Pictured, the tools unearthed from the burial pit, among which are projectile points (Nos. 1–7), unmodified flakes (8–10), retouched flakes (11–13), a possible backed knife (14), thumbnail scrapers (15 & 16), scrapers/choppers (17–19), burnishing stones (17, 20 & 21), and red ochre nodules (22–24)
The teenage female hunter was discovered with a hunting toolkit at the Wilamaya Patjxa in southern Peru.
The unexpected discovery of that one of the hunters' graves belonged to a woman prompted the team to investigate whether this case was a one-off — or whether women warriors were actually more common than was initially thought.
Consulting records of similar late Pleistocene and early Holocene burials that had been excavated across both North and South America, the researchers counted 429 individuals that had been laid to rest across 107 different sites.
Of this people, 27 had been buried alongside big-game hunting tools — with 11 being women and 15 men.

The find — along with an analysis of early burial practices more broadly — 'overturns the long-held "man-the-hunter" hypothesis', the US researchers said. Pictured, the Wilamaya Patjxa site
This sample, the researchers concluded, is sufficient to 'warrant the conclusion that female participation in early big-game hunting was likely non-trivial.'
Statistical analysis of the record of ancient hunter gathers concluded that between 30–50 per cent of hunters in these populations were women — a result in stark contrast to the same figures for recent hunter gathers, which are typically lower.
Even in agricultural and capitalist societies, hunting is usually a male-dominated activity with low levels of participation from women.
The researcher's review also revealed that the woman buried at Wilamaya Patjxa represents the earliest-known hunter burial in the Americas.
'We believe that these findings are particularly timely in light of contemporary conversations surrounding gendered labour practices and inequality,' said paper author and anthropologist Randy Haas of the the University of California, Davis. Pictured, researchers sift for remains at the Wilamaya Patjxa excavation site in the Andes
According to the researchers, their findings may shine light on the division of labour in early human societies — but such also raises new questions that need answers.
With their initial study complete, the team are now looking to explore how the sexual division of labour — and the consequences of such — varied across the early hunter-gatherer populations of the Americas, and how it changed with time.
The full findings of the study were published in the journal Science Advances.
The remains of the hunter and her artefacts were found in a grave at the high-altitude archaeological site of Wilamaya Patjxa, in what is today Peru
Researchers at the Wilamaya Patjxa archaeological site in Peru found an ancient grave that contained the remains of a female along with several weapons. What’s so interesting was the fact that she was a teenage hunter who died when she was between 17 and 19 years of age.
This discovery proves that women were just as good at hunting large animals as men were in ancient times around 9,000 years ago. It has been long believed that men hunted large animals while women gathered plants and herbs; however, this new discovery proves that females were able to hunt just like males. She was buried with several tools that included stone projectile points, butchery tools, and a knife. (Pictures of the archaeological site as well as the weapons found in the burial can be seen here.)
Randy Haas, who is an anthropologist from the University of California, Davis, and an author of the study, stated how significant this discovery was in regards to gender, “We believe that these findings are particularly timely in light of contemporary conversations surrounding gendered labor practices and inequality.” “Labor practices among recent hunter-gatherer societies are highly gendered, which might lead some to believe that sexist inequalities in things like pay or rank are somehow ‘natural’.” “But it’s now clear that sexual division of labor was fundamentally different — likely more equitable — in our species’ deep hunter-gatherer past.”
After the discovery of the grave, researchers were curious as to how common women hunters actually were in ancient times so they looked through old records of hunter-gatherer burials that date back to the late Pleistocene period (that finished approximately 11,700 years ago) and the early Holocene period (that started around 12,000 to 11,500 years ago). They analyzed the reports of 429 people who were buried in 107 locations around the Americas and they found that 27 of them were buried with big-game hunting weapons. And of those 27 skeletons, 11 were female. What’s even more amazing is that they calculated that between 30% and 50% of hunters during that time were in fact women.
In an interview with Live Science, Kathleen Sterling, who is an associate professor of anthropology at Binghamton University in New York but was not involved with the study, weighed in by stating, “This study should help convince people that women participated in big-game hunts.”
The study was published in the journal Science Advances where it can be read in full.
The CIA On Time Travel And The Holographic Reality - The Gateway Process
The CIA On Time Travel And The Holographic Reality - The Gateway Process
The “Analysis and Assessment of Gateway Process” was declassified by the CIA in 2017 This Gateway Process was a meditation lesson that taught humans to harness their own electromagnetic energy waves which come from their body. It also taught them how to control brain waves, and use them to, essentially, detach from time and space.
As the body is turned into a coherent oscillator vibrating in harmony with the surrounding electrostatic medium, the specific exercises included in the Gateway process allow the participant to build up the energy field surrounding their body, presumably by using energy from the earth’s resonant field (the same resonant field that was the basis for much of Nikola Tesla’s work) which the body then entrains because of its ability to resonate with it. This is big.
Aside from the obvious question of what nefarious purpose the CIA was hoping to achieve with this process, it’s hard to miss the deduction of what detaching the from time and space means — fourth dimensional travel with all that it implies (heaven, afterlife, a different dimension). This talks about many ideas such as binaural technologies, the law of attraction.
Hey guys, thanks for stoping by and visiting my site. Last night I found something I just had to share. Two large white objects on a crater floor that just scream out ancient aliens. One object has a square base with a round almost radar like sphere dome on it. The other is more significant because its a pyramid-like space ship that is hover...yes you read that right...hovering over the surface of the moon. Thats easy to see for yourself by looking at the shadow below it and compare it with the shadow of the other building I just described. 100% undeniable proof that aliens exist on Earths moon right now!
Demi Lovato Believes Extraterrestrials Will Save Humanity From Apocalypse If A Percent of World Population Mediate Hard
Demi Lovato Believes Extraterrestrials Will Save Humanity From Apocalypse If A Percent of World Population Mediate Hard
Demi Lovato is having a great time in her recent Instagram post coming back from a meditation retreat in the California desert, where she was primarily thinking about aliens. Now, after receiving her communication from the aliens zipping around our atmosphere, she wants everyone to join with her meditation so that the government will tell us extraterrestrials are real. Then the extraterrestrials can save us from worldwide destruction.
A few days ago, Lovato wrote on Instagram that she was in Joshua Tree for a few days with alien truther and UFO documentarian Steven Greer. Greer has released various films about his work, including 2017’s Unacknowledged and 2020’s Close Encounters of the Fifth Kind, both of which covered Greer’s alleged encounters with aliens and the related government cover-ups.
Lovato said she has “dug deep into the science of consciousness and experienced not only peace and serenity like I’ve never known, but I also have witnessed the most incredibly profound sightings both in the sky as well as feet away from me.” Now, she encourages fans and followers to meditate. She said that if 1% of the population meditate and make contact, our governments would be forced to acknowledge the truth about alien life among us and change our very negative path towards our planet’s destruction.
Hot, active volcanoes produce almost half of Jupiter’s moon Io’s sulfur atmosphere, according to new observations using the ALMA telescope. The rest comes from cold sulfur deposits that freeze on the surface, then sublimate in sunlight.

Io, one of the four large Galilean moonsof Jupiter, is the most volcanically active body in our solar system, even more so than Earth. It has over 400 active volcanoes and is often described as hellish. Io also has an extremely thin atmosphere, composed mostly of sulfur dioxide (SO2). This little world’s volcanoes regularly spew sulfur dioxide into its atmosphere. Still, scientists weren’t sure whether the atmosphere stems from hot sulfur dioxide coming directly from the volcanoes, or cold sulfur dioxide which accumulates on Io’s surface and freezes before sublimating into the atmosphere. Now they’ve determined it’s both.
Using the ALMA telescope in Chile, researchers at the University of California, Berkeley have announced that up to half of the sulfur dioxide in Io’s atmosphere comes directly from its volcanoes. The results have been published in two new peer-reviewed papers accepted for publication in The Planetary Science Journal, which you can read here and here.
It was not known which process drives the dynamics in Io’s atmosphere. Is it volcanic activity, or gas that sublimates from the icy surface when Io is in sunlight? What we show is that, actually, volcanoes do have a large impact on the atmosphere.
The answer, it turns out, is both.
Some of the sulfur dioxide does indeed freeze out onto the surface, the researchers found. This happens when Io passes through Jupiter’s shadow every 42 hours. When Io was being observed by the researchers on March 20, 2018, they noticed that radio emissions from the sulfur dioxide dropped exponentially. This meant that Io’s lower atmosphere, 6-12 miles (10-20 km) in altitude, collapsed and froze onto the surface.
The temperature during this period fell to -270 degrees Fahrenheit (-168 degrees Celsius), cold enough for sulfur dioxide to freeze. Io’s surface is typically about -230 degrees Fahrenheit (-150 degrees Celsius). Cold, but not quite cold enough for the sulfur dioxide to freeze out.
On September 2 and 11, 2018, the sulfur dioxide emissions rose again within 10 minutes after Io emerged from Jupiter’s shadow back into sunlight. De Pater said:
As soon as Io gets into sunlight, the temperature increases, and you get all this SO2 ice subliming into gas, and you reform the atmosphere in about 10 minutes’ time, faster than what models had predicted.
That explains where some of the frozen sulfur dioxide comes from. But the researchers noticed something else as well. ALMA detected abundant sulfur dioxide over the volcanoes, as well as low levels of the gas globally in Io’s atmosphere. This suggested that the more widespread gas was originating from unseen or “stealth” volcanoes. They emit sulfur dioxide, but not other smoke or particles that can be easily seen.
Right now, the researchers think that extra gas is coming from such stealth volcanoes, although they couldn’t completely rule out the possibility that it could be sulfur dioxide that isn’t completely condensing out onto the surface. As de Pater noted:
The SO2 that we see with ALMA when Io is in eclipse is at a very low level, and we can’t say if that is stealth volcanism or caused by SO2 not completely condensing out.
Io, as seen by the Galileo spacecraft on September 19, 1997.
Earlier observations from the Keck Observatory from last July, however, supported the stealth volcanism scenario. Keck detected abundant sulfur monoxide (SO) over the volcanoes, as well as widespread in the atmosphere. The researchers say that sunlight breaks the sulfur-oxygen bond in the sulfur dioxide that has been ejected hundreds of kilometers above the surface, creating the sulfur monoxide. De Pater said:
But then, when we looked at the SO with Keck, we can only explain the SO emissions, which are widespread on the surface, through this stealth volcanism, because excitation of the SO requires a very high temperature.
By observing Io in its orbit around Jupiter as it moved into and then out of Jupiter’s shadow, the researchers were able to figure out how much of the moon’s sulfur dioxide deposits came from freezing out on the surface and how much came from stealth or other volcanoes.Statia Luszcz-Cook from Columbia University in New York said:
When Io passes into Jupiter’s shadow, and is out of direct sunlight, it is too cold for sulfur dioxide gas, and it condenses onto Io’s surface. During that time, we can only see volcanically-sourced sulfur dioxide. We can, therefore, see exactly how much of the atmosphere is impacted by volcanic activity.
A volcanic eruption on Io, caught by Galileo’s cameras on June 28, 1997.
By using ALMA, scientists were able to “see,” for the first time, plumes of both sulfur dioxide and sulfur monoxide coming up from Io’s volcanoes. Two of those volcanoes, Karei Patera and Daedalus Patera, were erupting in March, and a third volcano was active in September.
The researchers now calculate that 30% to 50% of Io’s atmosphere is produced directly by active volcanoes.
A third gas, potassium chloride (KCI), was also detected by ALMA, and is a common component of lava. According to Luszcz-Cook:
We see KCI in volcanic regions where we do not see SO2 or SO. This is strong evidence that the magma reservoirs are different under different volcanoes.
The scientists are eager to learn more about Io’s magma as well, and are planning to observe the moon at additional radio wavelengths. These can probe several inches beneath the surface and provide clues about what Io’s magma is composed of and its temperature. They also want to know more about the temperature of Io’s lower atmosphere. De Pater said:
To measure the temperature of Io’s atmosphere, we need to obtain a higher resolution in our observations, which requires that we observe the moon for a longer period of time. We can only do this when Io is in sunlight, since it does not spend much time in eclipse. During such an observation, Io will rotate by tens of degrees. We will need to apply software that helps us make unsmeared images. We have done this previously with radio images of Jupiter made with ALMA and the Very Large Array.
How can a small moon like Io, way out in the outer solar system, have active volcanoes? Io is volcanically active due to tidal heating. The same side of Io faces Jupiter, just like the same side of the moon always faces Earth. The gravitational pull of Jupiter, as well as the moons Europa and Ganymede, creates tremendous friction and heating inside Io.
Io was last observed up close by NASA’s Galileo mission in the late 1990s/early 2000s. The current Juno orbiter has seen Io from farther away, but its primary mission is to observe Jupiter itself in detail as it orbits the giant planet. It has taken some cool images from a distance though.
Imke de Pater at the University of California, Berkeley, who lead the new study.
The new results help to solve the mystery of how Io’s atmosphere forms and how its volcanoes play a major part in that. But there are still many more questions to be answered – and new ones to be asked – about the solar system’s most active volcanic hotspot.
Bottom line:Active volcanoes produce almost half of Io’s sulfur atmosphere, according to new observations using ALMA.
Mysterious repeating bursts of radio waves that fire in random patterns might come from neutron stars blasting asteroids with magnetic winds that travel at nearly the speed of light, a new study finds.
Fast radio bursts, or FRBs, are intense pulses of radio waves that can give off more energy in a few thousandths of a second than the sun does in nearly a century. Scientists only discovered FRBs in 2007, and much remains unknown about their origins because of their brief existence.
Since fast radio bursts are rare and bright — the're visible across millions or even billions of light-years — researchers have often assumed they originate from cataclysmic events, such as stellar flares or colliding neutron stars. (Neutron stars are corpses of stars that died in catastrophic explosions known as supernovas; the gravity of these stellar remnants is powerful enough to crush protons and electrons together to form neutrons.)
The mystery of fast radio bursts deepened when scientists discovered the first repeating fast radio burst in 2016. When astronomers see repeating patterns in celestial events, they often think celestial mechanics might play a role — say, a planet completing an orbit around its star, or a fast-spinning neutron star known as a pulsar that blasts radio waves from its magnetic poles, flashing like a lighthouse as seen from the perspective of Earth.
But the radio bursts in the 2016 event, strangely, had random timing.
Asteroids and neutron stars
Now researchers suggest that asteroids orbiting neutron stars might help explain at least some repeating fast radio bursts, even those with random timing. The key to this concept is that strong winds of particles often blow outward not just from live stars like our sun but from dead ones as well, such as pulsars. Since pulsars are highly magnetic, their winds are too, and since pulsars spin rapidly, completing up to hundreds of revolutions per second, their winds can blast out at relativistic speeds — that is, at nearly the speed of light.
The scientists calculated that an object orbiting a pulsar — perhaps an asteroid — would carve a wake in the pulsar's wind. An electric current would circulate around this wake, and when the pulsar's wind crosses this wake, the researchers calculated, the resulting magnetic disturbances would generate a very narrow and extremely intense beam of radio waves.
The researchers noted that asteroids 0.6 to 6 miles wide (1 to 10 kilometers) orbiting their pulsars at one astronomical unit (AU) or closer would generate fast radio bursts of the intensities detected to date, especially if the pulsars had powerful magnetic fields. (One AU is the average distance between Earth and the sun, which is about 93 million miles or 150 million kilometers.)
The scientists noted that asteroids zipping through a pulsar's highly magnetic, superfast winds would continuously generate intense radio beams. But astronomers on Earth would only see these beams as bursts, during the rare instances when the neutron stars, asteroids and telescopes on Earth happened to line up.
"The short duration of the radio bursts is caused by the short time during which we observers are in the radio beam," study lead author Fabrice Mottez, an astrophysicist at the French National Center for Scientific Research and the Paris Observatory, told Space.com.
Facing the magnetar winds
The researchers also explored what repeating fast radio bursts might look like when created by asteroids flying through the highly magnetic, highly relativistic winds of magnetars, a rare type of neutron star that are the strongest magnets in the cosmos. They found asteroids around magnetars could generate fast radio bursts about a thousand times more powerful than the strongest one seen to date.
If this explanation is correct, the random patterns in repeating fast radio bursts are likely caused by a cluster of asteroids interfering with the neutron star's winds, the scientists noted, rather than a single rock. "In our model, there are a few hundred asteroids, each of them having its own beam," Mottez said. A moon-laden exoplanet around a pulsar or magnetar could also explain the phenomenon, the researchers noted.
Gravitational interactions between asteroids in swarms might lead to irregularities in each of their orbits that would also lead to unevenness in the timing of any bursts that astronomers detected, Mottez said.
In addition, the magnetic fields of pulsar and magnetar winds would fluctuate regularly in time with the rates these neutron stars spin at, which in turn would influence the directions of the radio beams from any orbiting object, potentially making the timing look more random, he added. Another cause of randomness, maybe the most important, would be wind turbulence, he said.
The scientists detailed their findings in a paper accepted on Oct. 7 by the journal Astronomy and Astrophysics, which was also posted to the preprint server arXiv.org.

SCIENTISTS THINK THEY'VE FINALLY SOLVED A 99 MILLION-YEAR-OLD FOSSIL MYSTERY
SCIENTISTS THINK THEY'VE FINALLY SOLVED A 99 MILLION-YEAR-OLD FOSSIL MYSTERY
Meet the albie — a highly unusual amphibian with a wild, slingshot tongue.
IN 2016, RESEARCHERS ANNOUNCED a landmark discovery made at a site in Myanmar: They had found 99 million-year-old chameleons, preserved in amber.
Fossils preserved in amber offer a far clearer glimpse at the ancient animal world than fossils embedded in rock or individual bones, but that doesn't mean mistakes cannot be made.
Now, a new paper published Thursday in the journal Science reveals the original study's researchers have a confession to make: These are not chameleons.
In fact, they are something else entirely.
Identifying a fossil animal's species is a complexprocess at best. Especially when you're dealing with 99-million-year-old fossils preserved in amber.
Juan Diego Daza is an assistant professor of biological sciences at Sam Houston State University and was the lead author on the 2016 study. Published in Science Advances, Daza and his colleagues reported the discovery of a dozen amber-bound fossils from Myanmar dating back to mid-Cretaceous period.
Amber is "good for trapping small and elusive animals that you won’t be able to find under other methods of fossilization," Daza tells Inverse. "These animals are so small that their chances of being fossilized with other methods — for example, normal, hard-rock fossils — would be very difficult."
Amber is also great for trapping other objects that can yield important clues to these animals' environments — a single grain of sand may reveal a beach habitat, for example, while a chance fly may suggest the fossilized animal's preferred prey.
But amber is no snow globe. With its dark, variable orange hue and rounded form, amber visually distorts the things it contains, making it difficult to easily identify details about the animals preserved within. This is made even harder when handling juvenile specimens, the bones of which would not have been fully developed when they were trapped.
Cut back to 2016. Daza and his colleagues were fairly confident that one of the fossils they found — which sported a nifty tongue bone — was an ancient chameleon.
It turns out that they were wrong.
FORENSIC FOSSILS
After publishing the 2016, Daza got a call. Another paleontologist, Susan Evans, had some bad (and good) news: Daza's chameleon was in fact a long-extinct species of amphibian — albanerpetontids, also known by the cute moniker "albies."
"The albanerpetontids — they’re very unusual amphibians," Daza says. "In a way, the body shape is similar to a salamander in the sense that they have four legs. And they have a tail — something that other amphibians that are alive today [don’t have]."
"MAYBE, SOME DAY, SOMEONE WILL DISCOVER ONE IN AN ISOLATED JUNGLE IN BORNEO OR SOMEPLACE IN THE WORLD WHERE NOBODY HAS GONE BEFORE."
With their claws and scales, albies are thought to have closely resembled a reptile — like a chameleon. But it turns out albies also shared another thing in common with the modern reptiles — that strange tongue bone.
"Albanerpetontids share with chameleons a unique bone in between the jaws, that’s basically a bone that supports the tongue. And that is very similar in both groups," Daza says.
To complicate matters, at the time, the majority of albie fossils had been found in Europe or North America, not Asia. Daza was left unsure what they had found, until he got an unexpected breakthrough in 2018.
At the end of 2018, Daza received an email from gemologist Adolf Peretti that would change everything. Peretti had 60 vertebrate fossil samples from Myanmar, and Daza suggested Peretti do a CT scan of the entire collection to better identify key details in the fossils.
The results turned out to be a boon for Daza — Peretti found a well-preserved adult albie specimen in his collection.
Comparing the juvenile in their study to Peretti's adult specimen allowed Daza and his colleagues to make key updates to the 2016 study.
They identified these fossils from Myanmar under a new genus and species: Yaksha perettii, named not only for Peretti, but also Hindu spirits, or yakshas, which are associated with nature.
In other words, Daza and his colleagues might have got the species wrong. But what they have instead discovered is perhaps the oldest example of a projectile tongue discovered in nature.
WAITING GAME
The albie's fast-moving "ballistic" tongue means it was likely a "sit-and-wait predator," according to Daza.
"They remain steady until a prey approaches and when the prey is in the range of their tongue, they will shoot at the tongue quickly. And, usually, the tongue is sticky at the end. And that allows them to engulf the prey and drag it to their mouths," he says.
But why does a chameleon, a reptile, share such a similar feature to an albie, an amphibian? It's all due to convergent evolution, Daza says.
"It’s a process in biology that we call convergence. It’s basically when two or more groups develop similar traits to perform the similar function," he explains.
"It’s the first amphibian of this group with such a good preservation, so it helped us to understand better the anatomy, and helped us do something that’s almost impossible to do with many fossils: to do a bone-by-bone analysis of each one of the bones that formed the skull," Daza adds.
The researchers also formed a better understanding of the creature's development. For example, it seems like albies don't necessarily have a larval stage, like a tadpole does before it becomes an adult frog.
"If this is a juvenile, and then this is an adult, we suspect, for example, when they hatch from their eggs, they are already almost formed. The lack the larvae stage that other amphibians might have," says Daza.
Albies had a long reign; the species existed for at least 165 million years and reportedly became extinct only two million years ago, leaving behind no living descendants today.
But is there a small chance that the albie may not actually be extinct, but is actually out there, just waiting to be found? It's actually not that far-fetched an idea.
"We don’t know. Maybe, some day, someone will discover one in an isolated jungle in Borneo or someplace in the world where nobody has gone before," Daza says.
Abstract:
Albanerpetontids are tiny, enigmatic fossil amphibians with a distinctive suite of characteristics, including scales and specialized jaw and neck joints. Here we describe a new genus and species of albanerpetontid, represented by fully articulated and three-dimensional specimens preserved in amber. These specimens preserve skeletal and soft tissues, including an elongated median hyoid element, the tip of which remains embedded in a distal tongue pad. This arrangement is very similar to the long, rapidly projecting tongue of chameleons. Our results thus suggest that albanerpetontids were sit-and-wait ballistic tongue feeders, extending the record of this specialized feeding mode by around 100 million years.
Lying out in rural Adams County, Ohio, in the United States, upon a plateau overlooking Bush Creek, is a curious mound of earth jutting out of the land, winding about in the unmistakable image of a snake for a full 1348 feet and averaging 3.9 to 4.9 feet in height, and it comes complete with an open-mouthed head and coiled tail, earning it its nickname “The Serpent Mound.” It is what is called an “effigy mound,” a type of earthen mound created in the shape of an animal, and it is the largest known such mound in the world, made all the more mysterious in that it curiously lies along the impact crater of some ancient meteor strike. First excavated in the late 1800s, we know no more about it now than we did then, its origins and purpose unclear, and so the Serpent Mound has managed to attract many mysterious stories to it, one of these being all of the giant skeletons that have apparently been found there.
While the exact origins and age of the mound are somewhat shrouded in mystery, the Serpent Mound is generally accepted to have been built by what is now called the Early Woodland Adena culture, which existed in the area from between 500 B.C. to 200 A.D., with the structure most likely dating to about 300 B.C., but the reasons for its existence have been debated. One idea is that it was created for some sort of mortuary purposes, as although the mound itself does not contain any remains, there are numerous smaller burial mounds peppering the area around it. It is thought that the serpent might have been constructed as a sort of protector of the graves or a beacon to guide lost spirits. This makes sense, as serpents and snakes were often depicted by the Native peoples as having magical or supernatural powers, and were seen as revered animals. Another idea is that it was for some sort of cosmological or astrological use, supported by the fact that the head and the tail of the serpent just happen to align very well with the summer solstice sunset and the winter solstice sunrise, as well as to yearly equinoxes. Another idea put forward by researcher Ross Hamilton in his book Star Mounds: Legacy of a Native American Mystery is that the Serpent Mound is merely one part of a larger “terrestrial zodiac,” linking together with other mounds across the country. However, no one is sure, and the mound remains quite a mystery.
The Serpent Mound
Adding to this is that the location on an impact crater has turned up various gravitational and magnetic anomalies in the area, leading to speculation that the construction was intentionally made here for this reason, and there have long been stories of freak weather patterns and anomalous lights in the area. The Serpent Mound has gone on to be known for UFO sightings and other weirdness, but perhaps the strangest thing here are the instances in which the remains of what appear to be actual giants, individuals allegedly measuring between 7 and 9 feet tall. One such report appears in 1872 in Historical Collections of Noble County Ohio, in which there were stumbled across some strange remains, which would be described:
The remains of three skeletons whose size would indicate they measured in life at least eight feet in height. The remarkable feature of these remains was they had double teeth in front, as well as in back of the mouth and in both upper and lower jaws. Upon exposure to the atmosphere the skeletons crumbled back to mother earth.
This is far from the only such report made from the vicinity of the Serpent Mound, and another was given in 1891 by American anthropologist and professor Frederic Ward Putnam, who was doing a study and excavation of one of the outlying burial mounds when he came across a skeleton of a relatively smaller size, standing at only 6 feet, but this would have been towering in ancient times, and it was also remarkable for its bizarre dental structure, which seems to have featured a double row of teeth. Putnam would write:
Several peculiarities of this skeleton are worthy of notice. It was that of a well-developed man…and probably about 25 or 30 years of age, he never had any wisdom teeth, and a search in the maxillary bone of one side showed that there was no wisdom tooth forming in the jaw. With this exception, he had a fine set of teeth, and still embedded in the premaxillary bone is a partly formed left incisor tooth. No corresponding formation can be seen on the opposite side of the suture, and this is probably a super-numerary tooth, although the small size of the lateral incisors is suggestive of their being persistent first teeth. As is often the case in skulls of this race, the crowns of the incisors are distinctly folded.
Putnam would surmise that this had been merely an adolescent, and that it would have achieved far greater size if it had not died. Putnam would allegedly discover several other skeletons in the area measuring 7 feet tall or taller, and with skulls that were “twice the usual thickness.” In 1894 a local farmer by the name of Warren Cowen also happened across some unusual graves, and an article at the time in The New York Times says of this:
Farmer Warren Cowen of Hilsborough, Ohio, while fox hunting recently discovered several ancient graves. They were situated upon a high point of land in Highland County, Ohio, about a mile from the famous Serpent Mound, where Prof. Putnam of Harvard made interesting discoveries. As soon as the weather permitted, Cowen excavated several of these graves. The graves were made of large limestone slabs, two and a half to three feet in length and a foot wide. These were set on edge about a foot apart. Similar slabs covered the graves. A single one somewhat larger was at the head and another at the foot. The top of the grave was two feet below the present surface.
Upon opening one of the graves a skeleton of upwards of six feet was brought to light. There were a number of stone hatchets, beads, and ornaments of peculiar workmanship near the right arm. Several large flint spear and arrow heads among the ribs gave evidence that the warrior had died in battle. In another grave was the skeleton of a man equally large… Several pipes and pendants were near the shoulders. In other graves, Cowen made equally interesting finds. It seems that the region was populated by a fairly intelligent people, and that the serpent mound was an object of worship. Near the graves is a large field in which broken implements, fragments of pottery, and burned stones give evidence of a prehistoric village.
There would apparently be made at least 17 reports listed in Smithsonian ethnology reports of outsized remains of 7 feet and over found in mounds surrounding Serpent Mound, and it has led to speculation that some race of giant individuals may have called this place at home and been closely in league with the Natives of the area. What are we to think of all of this? It is all certainly a mysterious place, but are there mysteries here that are even stranger than most? What are are we to make of the reports of giant-sized people living here, and is there anything to such reports at all? The mystery remains, and the Serpent Mound of Ohio is certainly an inscrutable feature of the landscape here.
There are some strange and supernatural creatures lurking in our midst that I think are interconnected. How and why, I have to admit, I don’t know. But, as I see it, there’s no denying the links. Today, I’ll be addressing the appearances of these paranormal entities. And tomorrow I’ll be focusing on their strange abilities. So, let’s begin. There is one thing that stands out when it comes to such things as the Men in Black,the Women in Black, and the Black Eyed Children. It’s the color of their skin. In many cases it’s deathly white. In fact, in some cases it’s almost as if they have something somewhat similar to albinism. Maybe, they do. And, with that said, let’s have a look at this particular condition. Healthline says: “Albinism is a rare group of genetic disorders that cause the skin, hair, or eyes to have little or no color. Albinism is also associated with vision problems. According to the National Organization for Albinism and Hypopigmentation, about 1 in 18,000 to 20,000 people in the United States have a form of albinism.” The U.K.’s National Health Service state: “Albinism affects the production of melanin, the pigment that colours skin, hair and eyes. It’s a lifelong condition, but it doesn’t get worse over time. People with albinism have a reduced amount of melanin, or no melanin at all. This can affect their colouring and their eyesight. Albinism is caused by faulty genes that a child inherits from their parents.”

eSight provides the following: “Ocular albinism is an inherited condition that affects a person’s eyes. People with ocular albinism lack melanin, which gives eyes their blue, green, brown, or hazel color. Melanin also acts like sunscreen to protect the eyes from the sun’s harmful UV rays. It can cause vision problems, such as nearsightedness, farsightedness, and astigmatism. Ocular albinism affects the retina, which is the light-sensitive tissue lining the inside of the eye, and the optic nerve that sends signals about what the person sees to the brain. The condition prevents the retina from developing properly, which causes things to look blurry.” eSight also provides this: “Options and support include vision correction, support groups, and low vision aids. Vision correction with glasses can sharpen vision somewhat. Sunglasses, transition lenses, or special filter glasses can relieve hypersensitivity to light, although they may reduce visual acuity when worn indoors.” As for the matter of the Sun and albinism, the Mayo Clinic staff give us this information: “People with albinism have skin that is very sensitive to light and sun exposure. Sunburn is one of the most serious complications associated with albinism because it can increase the risk of developing skin cancer and sun damage-related thickening of the skin.”
Albino wallaby
With that all said, it’s worth noting that those aforementioned strange creatures – the Men in Black, the Women in Black and the Black Eyed Children – appear to exhibit aspects of something not too far removed from albinism. For the most part, all three groups avoid the Sun: nighttime is when they are usually about. Yes, there are some cases in which the BEC, the WIB and the MIB descend on the homes of their targets (or “victims” might be a better word to use) during the day. Interestingly, though, in the daylight-based incidents the W.I.B. almost always wear long wigs (in a “bangs” style) and large, wrap around sunglasses. The MIB sport Fedoras. The sunglasses, too. Sometimes both the men and the women even wear gloves. As for the BEC, they almost always wear hoodies, and with the hood pulled down just about as far as possible. In other words, the clothing and the headgear are almost certainly not forms of fashion. Taking into consideration all of the above – the hats, the hoods, the wigs, the gloves and the glasses – their “fashions” may actually be essential items of vital protection.
Could it be there is an albino-like connection to all of the aforementioned groups? Granted, it’s nothing more than a theory. It is, however, a theory that makes some sense.
They believe that there was once anicy planet that was kicked out of our solar systemand that it had an effect on how some of the planets orbit our sun. When our sun was very young, the planets formed from a swirling disk of gas and dust. It was suggested that the large planets orbited the sun in a different way from their current patterns but gravitational reactions forced them into their current orbits.
Researchers have discovered evidence that there was once another ice giant like Neptune which used to sit between Saturn and Uranus on the edge of the solar system. This would mean there may have been nine planets in the solar system, or 10 if you include Pluto before it was downgraded to a dwarf planet in 2008.
The Sun was once surrounded by a disk of gas, dust and rocks.
Over billions of years, the debris collected to give us the planets we know today.
However, the more massive planets, such as Jupiter, Saturn and Neptune, played gravitational tug of war, giving way to the order of the solar system.
Now, researchers from the Carnegie Institution for Science ran more than 6,000 computer simulations to show what the solar system looked like before the planets took their positions.

Carnegie postdoctoral fellow Matt Clement said: “We now know that there are thousands of planetary systems in our Milky Way galaxy alone.
“But it turns out that the arrangement of planets in our own Solar System is highly unusual, so we are using models to reverse engineer and replicate its formative processes.
“This is a bit like trying to figure out what happened in a car crash after the fact — how fast were the cars going, in what directions, and so on."
Through their simulations, the team discovered that the final arrangement of Uranus and Neptune, the two planets on the outer edge of the solar system, was determined by the Kuiper belt - a circumstellar disc of planetary debris and comets.
The research also showed that the Kuiper belt helped to "eject an ice giant" which was kicked out when the solar system was still forming.
Not only have the team helped to discover a potential lost world, but the research could be used to search for life on other planets.
Dr Clement continued: “This indicates that while our Solar System is a bit of an oddball, it wasn’t always the case.
“What’s more, now that we’ve established the effectiveness of this model, we can use it to help us look at the formation of the terrestrial planets, including our own, and to perhaps inform our ability to look for similar systems elsewhere that could have the potential to host life.”
Researchers from the United States have conducted simulations in regards to our Solar System having an extra planet at one time as well as the orbital patterns of our current planets.
They believe that there was once an icy planet that was kicked out of our solar system and that it had an effect on how some of the planets orbit our sun. When our sun was very young, the planets formed from a swirling disk of gas and dust. It was suggested that the large planets orbited the sun in a different way from their current patterns but gravitational reactions forced them into their current orbits.
The researchers attempted to figure out how the planets’ orbits changed throughout history so they ran 6,000 different simulations and they found that Jupiter and Saturn started off with “eccentric” oval-shaped orbits around the sun. It is believed that when Jupiter was very young, it orbited the sun three times compared to two orbits completed by Saturn, but based on their orbital patterns today it didn’t make a lot of sense. According to the new research, they think that Jupiter probably completed two orbits around the sun for each one made by Saturn.
Additionally, they found that Uranus and Neptune were affected by the gravitational pull of the Kuiper belt as well as by a lost planet – an icy world that was once located between Saturn and Uranus.
Matt Clement, who is a planetary scientist from the Carnegie Institution for Science in Washington as well as an author of the paper, explained this process further, “We now know that there are thousands of planetary systems in our Milky Way galaxy alone.” “But it turns out that the arrangement of planets in our own Solar System is highly unusual, so we are using models to reverse engineer and replicate its formative processes.” “This is a bit like trying to figure out what happened in a car crash after the fact — how fast were the cars going, in what directions, and so on.”
He went on to say, “This indicates that while our Solar System is a bit of an oddball, it wasn’t always the case,” adding, “What’s more, now that we’ve established the effectiveness of this model, we can use it to help us look at the formation of the terrestrial planets, including our own,” as well as to “inform our ability to look for similar systems elsewhere that could have the potential to host life.”
Their research was published in the journal Icarus and can be read in full here.
I found this on the official NASA Instagram yesterday. A huge glowing object is seen very close to the space station and seems also to be over the hurricane. The object also has a smudge area a little bit above it, which I believe to be the same object, but its still moving. The UFO may have slowed down, but not actually stop at all. So that would explain why the astronaut missed it or why NASA didn't seem to notice it. UFO, reflection, meteor or secret spy spacecraft. You decide, but for me...it looks like a UFO.

Evidence of Alien Spacecraft Firing Huge Beam at The Sun
NASA's satellite EIT 304 captured a massive alien spacecraft firing a beam at the sun. The images show that two craft appear in space next to the sun on which one craft firing a huge beam at the sun.
The remarkable event took place on November 1, 2020 and evidence that these kind of alien spacecraft not only flying extremely close to the sun, but they fire huge beams at the sun too.
Even though the reason is not known, it is said that intelligent aliens might survive by collecting, storing and harnessing the power of the sun.

Huge UFO sitting over Stonehenge on Halloween night 2020!
This bright formation of lights was filmed hovering in Wiltshire near a Stonehenge. This happened on Halloween night, October 31st 2020.
Witness report:
Driving back from Devon yesterday we spotted a massive bright light in the sky on the left of the A303. It was orange and very bright artificial lighting. My partner said it may have been multiple lights but I could have sworn it was one solid beam with a bit of a hue around it to the left and right. We considered drones or spotlights but this didn’t match what it looked like. The light was stationary, below the clouds and unmoving. We filmed for approximately 3 minutes and then it was gone. Just disappeared.
A WEIRD, ANCIENT SHRIMP HAS CHANGED SCIENTISTS' UNDERSTANDING OF EVOLUTION
A WEIRD, ANCIENT SHRIMP HAS CHANGED SCIENTISTS' UNDERSTANDING OF EVOLUTION
Just a little evolutionary hiccup along the way.
DURING THE CAMBRIAN PERIOD, the world’s oceans were teeming with strange, swimming, segmented creatures.
Over the course of millions of years, these elongated, millipede-like animals would eventually evolve to become modern arthropods: crustaceans like crabs, arachnids like scorpions, and insects like bees and ants.
But some 500 million years ago, these aquatic Cambrian beasts were rather more experimental when it came to their physical traits and body plans than their more familiar descendants. There was the 3-inch-long Opabinia,with 5 eyes balanced on stalks and an elephant trunk-like mouth, and the predatory Radiodonta species, replete with two spine-laden, curving and segmented appendages designed to capture prey.
But there was another creature swimming around Earth's oceans, showcasing both of these strange features, and so much more. Enter the Kylinxia zhangi.
This newly discovered, shrimp-like species is described in a paper published Wednesday in the journal Nature.
In the paper, the researchers reveal that rather than just one special feature, this small fossil arthropod possesses a melting pot of physical traits, including five eyes on stalks and curved, spiny hooks extending upward from the front of its body like talons. It appears to have been armored, too. The fossil has a fused head shield, an armored, segmented body, and other claw-like appendages down its shell.
The discovery helps scientists understand how Cambrian arthropods may have been related to each other, and how their legacy lives on in crabs and insects today.
Diying Huang is a co-author on the paper and professor at the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences. He tells Inverse that while modern arthropods may seem like a diverse bunch, they have nothing on their ancient ancestors.
“Modern arthropods are abundant and diverse. They are everywhere and familiar [to] people," he says. “The Cambrian arthropods are also complex, not only the diversity, [but] also the morphology, anatomy, and functional morphology.”
In a nod to its strange physiology, the researchers dubbed the new shrimp Kylinxia zhangi, named after Kylin, a Chinese mythological chimera. And while its mismatched body is curious, it is also a rare sign of a pivotal moment in ancient animal evolution. Kylinxia may be a “transition” species, able to shed light on the evolutionary relationships between the other animals that lived at the same time.
“[These] groups would [have] lived in the Cambrian sea at the same time or similar time,” Huang says. “They could have [the] same ancestor in an earlier time.”
Researchers use a process called phylogenetic analysis to try and reconstruct, on the basis of its strange physiology, Kylinxia's evolutionary pathway among arthropods. The analytic technique pays attention to details like how many segments a creature has, the shape of its head, or how spiky its appendages are. It assumes that similarities between animals are more likely to be based on evolutionary relationships than chance.
The fact that Kylinxia possess spiny, hunting appendages shaped like those of Radiodonta, combined with the fact these are upturned, like another arthropod, Megacheira, and a Megacheira-like body, leads the researchers to believe that Radiodonta and Megacheira inherited their appendages from a common ancestor, rather than evolving independently in each creature.
In other words, it’s the same creepy appendage, just flipped.
Adding Kylinxia to the ancient tree also sheds light on the evolution of modern arthropods. Previous work had suggested that Megacheira, with their spiny appendages, were closely related to Chelicerata, the group that includes modern scorpions and spiders, as well as a group of ancient animals with antennas, which may have evolved into insects, like bees and ants.
The spiny appendages on Megacheira, the mouth pinchers on scorpions and spiders, and antennas on bees are all similarly located on these animals' bodies, leading researchers to believe they may have all evolved from a creature or creatures with similar structure.
But researchers didn’t know what came first. Did the spiny appendages evolve into antennas, which evolved into pinchers? Or were mouthparts first? The discovery of Kylinxia ages the spiny appendages, suggesting they gave rise to both pinchers and antennae along separate lineages, rather than mouthparts arising from antennae, or vice versa.
The undersea world of little Kylinxia, swirling with segmented, many appendage beasts, is very unlike that of the modern oceans. But the diverse morphological and ecological experimentation by early arthropods like it “probably laid the foundation for their later evolutionary successes," the researchers say.
Abstract:
Resolving the early evolution of euarthropods is one of the most challenging problems in metazoan evolution1,2 . Exceptionally preserved fossils from the Cambrian period have contributed important palaeontological data to deciphering this evolutionary process3,4 . Phylogenetic studies have resolved Radiodonta (also known as anomalocaridids) as the closest group to all euarthropods that have frontalmost appendages on the second head segment (Deuteropoda)5–9 . However, the interrelationships among major Cambrian euarthropod groups remain disputed1,2,4,7 , which impedes our understanding of the evolutionary gap between Radiodonta and Deuteropoda. Here we describe Kylinxia zhangi gen. et. sp. nov., a euarthropod from the early Cambrian Chengjiang biota of China. Kylinxia possesses not only deuteropod characteristics such as a fused head shield, a fully arthrodized trunk and jointed endopodites, but also fve eyes (as in Opabinia) as well as radiodont-like raptorial frontalmost appendages. Our phylogenetic reconstruction recovers Kylinxia as a transitional taxon that bridges Radiodonta and Deuteropoda. The most basal deuteropods are retrieved as a paraphyletic lineage that features plesiomorphic raptorial frontalmost appendages and includes Kylinxia, megacheirans, panchelicerates, ‘great-appendage’ bivalved euarthropods and isoxyids. This phylogenetic topology supports the idea that the radiodont and megacheiran frontalmost appendages are homologous, that the chelicerae of Chelicerata originated from megacheiran great appendages and that the sensorial antennae in Mandibulata derived from ancestral raptorial forms. Kylinxia thus provides important insights into the phylogenetic relationships among early euarthropods, the evolutionary transformations and disparity of frontalmost appendages, and the origin of crucial evolutionary innovations in this clade.

Scientists already had Psyche classified as a metallic asteroid, but new observations with the Hubble telescope reveal its rusty surface and provide scientists with a unique view into what Earth-like planets are like during their formation.
Artist’s concept of 16 Psyche, a massive asteroid located 230 million miles (370 million km) away from Earth. New ultraviolet observations of the asteroid and its surface revealed that it may be made entirely of nickel and iron, making it the perfect candidate to tell the tale of how Earth-like planets are formed. It is thought to be the core of a failed planet formation.
A team of scientists led by Tracy Becker of the Southwest Research Institute in San Antonio, Texas, said on October 26, 2020, that the deepest-ever ultraviolet observations of the asteroid 16 Psyche have revealed a secret: the asteroid may be made entirely of iron and nickel, and its surface may be covered in rust. Psyche was already classified as an M-type asteroid, that is, an asteroid known to contain a significant percentage of metal. It’s one of the most massive objects currently known to be orbiting in the solar system’s asteroid belt between Mars and Jupiter. Generally speaking, metal asteroids are rare, and the study revealed that Psyche may be the most “metal-like” of all known asteroids. Thus Psyche has a story to tell about solid planets like Earth and what happened when they were forming 4 1/2 billion years ago.
At 140 miles (225 km) in diameter, Psyche spans roughly the distance between Philadelphia and Washington, D.C., and provides plenty of surface for scientists to observe and study. New ultraviolet (UV) observations of the massive asteroid have revealed that Psyche’s surface may be mostly made of iron, but scientists believe further study is required to confirm their findings, as lab models provided conflicting outcomes.
Tracy Becker, a planetary scientist at the Southwest Research Institute, is the lead author on the new study.
Becker, a planetary scientist at the Southwest Research Institute, is the lead author on the paper. She told EarthSky:
The way that Psyche reflects UV light is very similar to the way iron and metallic meteorites reflect UV light; the UV spectrum of Psyche is similar to that of iron. But we note that in our computer models, we found we could reproduce the spectrum of Psyche with as little as 10% of iron mixed into other materials. So, we can’t conclude definitively just how much iron is on the surface, but it does look like some metals are there.
Scientists also found another way to detect iron on the surface: by looking for rust. After all, where there is iron, there may be rust, or something similar. To find it, Becker’s team focused their efforts on hunting for spectral evidence of iron oxide, which is typically observed on Earth and other bodies as rust. The scientists needed a way to ferret out iron oxide signatures. While unable to scoop up a sample from 230 million miles (370 million km) away, ultraviolet (UV) observations provided the solution. UV light is made up of short wavelengths that are invisible to the human eye but carry high energy, and are capable of damaging living tissue and causing sunburns and skin cancer. But in astronomy, these short wavelengths of light are beneficial and can help scientists understand chemical composition, density, and temperature. For these researchers, UV light was the key to help unveil iron oxide on the surface of Psyche.
Becker said:
Recent laboratory work shows that you can see the iron oxide signatures in the UV better than at other wavelengths, so we wanted to look for those. The UV is also very sensitive to the uppermost layer of the planetary body, so we would be able to see how much of the asteroid’s surface has been [changed over time].
Becker’s team engaged in patient observation of Psyche, taking UV measurements on both sides of the asteroid to get a complete picture of its surface. The team’s patience paid off when they saw evidence of iron oxide. Becker said in a statement:
We were able to identify, for the first time on any asteroid, what we think are iron oxide ultraviolet absorption bands. This is an indication that oxidation is happening on the asteroid, which could be a result of the solar wind hitting the surface.
The Curiosity rover took this self-portrait while crossing Vera Rubin Ridge on Mars, showing off the reddish dirt that covers the surface of the planet. That red hue is due to the heavy presence of iron oxide, or rust particles, that are blown around the surface by Martian winds. The presence of rust on celestial bodies like Mars and Psyche gives scientists clues to the amount of iron that exists on their surfaces.
Although this is the first time that scientists have observed evidence of iron oxide on an asteroid, it isn’t the first time that rust has been observed in our solar system. Mars – often referred to as the red planet due to its hue – is covered in rust particles, which are blown around on the planet as winds shape its surface. And while the appearance of rust on Psyche doesn’t necessarily mean that the asteroid is corroding, scientists did detect evidence of surface changes.
During observations, Becker’s team noticed that Psyche’s uppermost layers appeared more reflective at deeper UV wavelengths. While Becker said this phenomenon requires further study, she noted that the observed brightening may be the result of further space weathering. She said:
All planetary bodies are exposed to space weathering by the sun, and other processing through small impacts by micrometeorites, that will change their surfaces. Characterizing space weathering is helpful for understanding how long the surface has been exposed to space.
Becker’s team carried out UV emission observations on Psyche using the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope (HST). Before the study, no other previous UV observations of Psyche had been made, in part due to the difficulty of conducting studies using UV light. Becker said:
We cannot observe any objects in the ultraviolet from ground-based telescopes, since our atmosphere blocks UV light. The only way to observe solar system objects in the UV is with space-based telescopes, which are limited. Psyche hadn’t been observed at these wavelengths – mid- and far-UV – of light before. There had been near-UV observations from the International Ultraviolet Explorer (IUE), but these HST observations go farther in the UV than ever before.
Before the new study, scientists already believed Psyche to be the leftover core of a protoplanet that never finished forming. The new observations, and the discovery of iron oxide signatures, have revealed the asteroid to be truly unique, and even more Earth-like than previously believed. Becker said:
We’ve seen meteorites that are mostly metal, but Psyche could be unique in that it might be an asteroid that is completely made of iron and nickel. Earth has a metal core, a mantle and a crust. It’s possible that as a Psyche protoplanet was forming, it was struck by another object in our solar system and lost its mantle and crust.
NASA’s Psyche mission will launch toward the asteroid of the same name in 2022. Scientists hypothesize that this asteroid is actually the leftovers of a failed planet formation. New ultraviolet studies with Hubble have shown that Psyche is even more unique than that, as it may consist entirely of nickel and iron, and that the iron may be rusting.
The leftovers from this stellar hit-and-run have long sparked interest in Psyche. In 2017, NASA announced a mission to the asteroid, which will be the first such mission to an object not made of rock or ice. Set to launch in 2022, NASA’s orbiter will reach Psyche in 2026, and either confirm or deny scientists’ observations and theories. No matter the outcome, Becker is looking forward to seeing what secrets the mission will reveal. She said:
What makes Psyche and the other asteroids so interesting is that they’re considered to be the building blocks of the solar system. To understand what really makes up a planet and to potentially see the inside of a planet is fascinating. Once we get to Pysche, we’re finally going to understand if that’s the case, even if it doesn’t turn out as we expect. Any time there’s a surprise, it’s always exciting.
Bottom line: New observations of asteroid Psyche with the Hubble Space Telecope have revealed that the asteroid may be made entirely of nickel and iron. Its surface appears to be rusting. The new work provides scientists with a unique view into what Earth-like planets are like during formation.
