It is official: WikiLeaks founder Julian Assange will be extradited to the United States to face espionage charges after spending a decade in the United Kingdom being tortured.

BitChute policy officer Amy Peikoff joined Alex Jones of Infowars to discuss Assange’s mistreatment, as well as talk about ways to help secure journalistic freedom for all moving forward – watch the interview below:

Assange is trying to appeal his extradition, but U.S. lawyers are petitioning a London court to block the appeal and send Assange back to America immediately.

"What you would hope is that if there were any court proceeding and he were allowed to appear and actually speak for himself that he could explain to people the truth about what is going on," Peikoff told Jones.

"This is a case of journalism versus authoritarian power, and we need to preserve the cause of the First Amendment and free speech of journalism against the powers that be."

What Jones wants to know is why Assange is not allowed to appear and speak for himself but Charles Manson, a mass murderer was, to which Peikoff offered the following explanation:

"I think they are afraid that if Assange is allowed to speak for himself and people can actually see the principle at stake that they would support him. Basically there’s [sic] two alternatives: you can deal with people through persuasion or you can deal with people through force. And what they are revealing is that they do not have arguments on their side, that all they have is force and they are applying it mercilessly in the face of true principles – principles on which our country was founded uniquely. They are relinquishing it to the extent that they do not let this man free."

The Julian Assange saga has been going on for ages after the powers that be punished the WikiLeaks founder for releasing vast quantities of confidential U.S. military records and diplomatic cable, which allegedly put the lives of government agents in danger.

Supporters of Assange say he is a hero who is undergoing classic persecution for exposing the wicked and often illegal behavior of the U.S. deep state. They hail him as a true journalist, which as we know is hard to come by in modern times.

Assange’s lawyers say the case against him is politically motivated, arguing that Assange is being targeted for exposing "state-level crimes." They also claim Donald Trump requested "detailed options" on how to kill Assange for trying to do the right thing.

Lawyers for the U.S., arguing contrary to this, say Assange’s prosecution is merely "based on the rule of law and evidence," with attorney Clair Dobbin stating that he "indiscriminately and knowingly published to the world the names of individuals who acted as sources of information to the U.S."

"It is these core facts which distinguish the position of the appellant from the New York Times and other media outlets," Dobbin added. "It is this which forms the objective basis for his prosecution. It is these facts which distinguish him, not his political opinions."

Assange faces 17 charges of espionage and one charge of computer misuse for publishing classified U.S. documents on his WikiLeaks platform some 15 years ago. It is now up to the High Court in London to decide whether Assange will be allowed to further argue his case before a U.K. court or face extradition back to the U.S.

[There are pretty amazing images at the source link below. This means that scientists can study these ancient bugs in tremendous detail! Jan]

Two tiny fossils, each smaller than an aspirin pill, contain fossilized nerve tissue from 508 million years ago. The bug-like Cambrian creatures could help scientists piece together the evolutionary history of modern-day spiders and scorpions.

Still, it’s not clear exactly where these fossils — both specimens of the species Mollisonia symmetrica — fit on the arthropod evolutionary tree, said Nicholas Strausfeld, a regents professor in the Department of Neuroscience at the University of Arizona, who was not involved in the study.

That’s because some features, like the animals’ eyes and nerve cords, can be clearly identified in the fossils, but other parts of the nervous system cannot be so easily spotted. In particular, it’s unclear whether or not the animals carry a brain-like bundle of nerves called a synganglion, and without this key piece of evidence, their relation to other animals remains fuzzy, Strausfeld said.

Related: From dino brains to thought control — 10 fascinating brain findings

Where the synganglion would sit, instead there’s "this mess in the middle of the head," said first author Javier Ortega-Hernández, an invertebrate paleobiologist at Harvard University and curator of the Harvard Museum of Comparative Zoology. The researchers can tell that this mess is nerve tissue, but they can’t discern its exact organization.

"It is … true that we do not have every single characteristic of the nervous system of this animal mapped out, because the fossils only tell us so much," Ortega-Hernández said. The researchers acknowledge this uncertainty in their new report, published Jan. 20 in the journal Nature Communications, and present a few different ideas as to how these fossils relate to ancient and modern-day critters. If more fossilized M. symmetrica are uncovered in the future, the species’ place on the tree of life may eventually be resolved.

‘A stroke of luck’
Finding fossilized nerve tissue from the Cambrian period, which took place between about 543 million and 490 million years ago, is a "rarity," Ortega-Hernández said. "It’s really a stroke of luck."

Scientists uncovered the first evidence of a fossilized arthropod brain from the Cambrian period about a decade ago, according to a 2012 report in the journal Nature Communications; arthropods are invertebrate animals in the phylum Arthropoda, a group that includes modern insects, crustaceans and arachnids, like spiders. Since that initial discovery 10 years ago, preserved nerve tissue has been found in more than a dozen Cambrian fossils, most of them arthropods, Ortega-Hernández said.

The fossils featured in the new study were found not at a field site, but in the depths of the museum collections at the Harvard University Museum of Comparative Zoology in Cambridge, Massachusetts, and the Smithsonian Institution in Washington, D.C. Both specimens were discovered in mid-Cambrian Burgess Shale deposits from British Columbia.

The Harvard fossil measures about 0.5 inches (13 millimeters) long and 0.1 inches (3.5 mm) wide at its widest point; the fossil is oriented such that you’re looking down at the arthropod from above. The Smithsonian fossil, on the other hand, offers a side-view of M. symmetrica; this specimen measures only 0.3 inches (7.5 mm) long and 0.06 inches (1.7 mm) tall.

To the naked eye, neither fossil looks particularly exciting, Ortega-Hernández said. Regarding the miniscule Smithsonian fossil, in particular, "superficially, it is extremely unremarkable," he said. M. symmetrica has a simple exoskeleton, consisting of a head shield, segmented trunk and posterior shield — somewhat like the exoskeleton of a pillbug, but long and skinny.

The researchers suspect that the arthropod also had seven pairs of tiny appendages, two fangs and six pairs of little limbs; that’s based on a 2019 study, published in the journal Nature, that described a fossil from a different species in the Mollisonia genus that bore such appendages. However, it’s highly unusual to find Mollisonia fossils with intact limbs, and both fossils used in the new study lack appendages, Ortega-Hernández noted.

Despite the fossils’ lack-luster appearance, when he placed the Smithsonian M. symmetrica fossil under a microscope, he spotted something intriguing, Ortega-Hernández said. "I realized, ‘Ooh, there’s something funky inside of this animal, inside of this fossil,’" he said. He found that locked inside both of these inconspicuous arthropods were well-preserved nervous systems. The fossilized nerves look like inky black splotches, because the fossilization process transformed the tissue into organic carbon films.

In the Smithsonian fossil, a bulbous eye can be seen in the arthropod’s head and a nerve cord can be clearly seen running down the length of its belly, with some nerves jutting out from its underside. In the Harvard specimen, one can see two huge, orb-like eyes on the head, and a bit of the nerve cord peeking out from beneath the animal’s digestive tract, which obscures the rest of the cord.

In both fossils, the study authors reported seeing optic nerves that run from the arthropods’ eyes into the main body, but Strausfeld said the evidence for these nerves is "ambiguous," and ideally, these features would be clearer. And in both specimens, the authors noted that there’s some sort of nerve tissue present in the head, but it’s unclear whether this structure is a brain-like synganglion or something else entirely.

"We can see there’s something in there, but we don’t have enough resolution to be able to say, ‘Oh, it’s definitely organized in this way or that way,’" Ortega-Hernández said.

Uncertainty in the data

This uncertainty in the fossil record means the precise relationship of M. symmetrica to other animals also remains murky, Ortega-Hernández said. But based on the features present in the arthropods, the team constructed two evolutionary trees.

Both trees indicate that M. symmetrica and modern chelicerates share a common ancestor, suggesting that the ancient animal’s relatively simple nervous system gave rise to the highly condensed brain seen in modern-day members of this group, such as scorpions, spiders, horseshoe crabs and ticks. However, the trees differ in where they position other important arthropod groups from the Cambrian, including one known as the megacheirans; these groups have similar nervous systems to modern chelicerates.

Depending on where these various groups sit on their evolutionary tree, their placement either shows that chelicerate-like brains evolved in a stepwise manner through time, or it hints that such nervous systems evolved independently and at different times in some Cambrian arthropods and modern chelicerates, through convergent evolution, Ortega-Hernández said.

With the data at hand, Strausfeld said he would be "cautious" about attempting to place M. symmetrica anywhere on an evolutionary tree. In order to do so, he said he’d need clearer evidence of how the arthropods’ optic nerves and synganglion (or lack thereof) are structured, as well as evidence of nerves extending out to the roots of the animal’s limbs.

"I think one needs a better preparation, a better specimen" than the ones examined so far, Strausfeld said. "Maybe there’s another specimen lying around somewhere in a museum."

[Incredibly large and nasty things have happened on earth very many times in the past on a scale you can't imagine. Jan]

Deep beneath the Mediterranean seabed circling the Greek island of Santorini, scientists have discovered the remnants of one of the most explosive volcanic eruptions Europe has ever seen.

A giant layer of pumice and ash, which is up to 500 feet (150 meters) thick, revealed that around half a million years ago, the Santorini volcano erupted so explosively it was 15 times more violent than the Hunga Tonga-Hunga Ha’apai eruption of 2022. The Tonga eruption shattered several records, triggering the fastest atmospheric waves ever seen and the first known mega-tsunami since antiquity.

"We know that this volcano’s had many big, explosive eruptions — sort of Krakatoa style," study lead author Tim Druitt, a professor of volcanology at the University of Clermont Auvergne in France, told Live Science. But the newly discovered deposits point to a cataclysmic blast "that we didn’t even know had existed."

Extensive land-based research has previously painted a relatively detailed picture of past volcanism across the Hellenic Island Arc — a string of volcanic islands stretching from Greece to Turkey along a curved line where the African tectonic plate plunges beneath Europe. For instance, geologists knew that Santorini emerged from the sea about 400,000 years ago, as successive eruptions piled volcanic debris onto the seafloor. The present-day Santorini archipelago formed during the Late Bronze Age (1600 to 1200 B.C.), when the explosive Minoan eruption blasted the top off what was then one island. A magma chamber beneath the Kameni islands, in the center of the Santorini caldera, still feeds the volcano today.

The JOIDES Resolution drilling ship used for the study on the Mediterranean Sea at sunset.

But there’s only so much scientists can learn on land, Druitt said, because erosion from rain and wind wipes away some geological evidence. "That’s why we moved to the marine realm, because in the sea it’s calmer," he said.

To find out more about the region’s volcanic activity, Druitt and his colleagues drilled into marine sediments around Santorini in late 2022 and early 2023. With help from the International Ocean Discovery Program, the researchers extracted sediment cores from up to 3,000 feet (900 m) below the seafloor at 12 drilling sites.

The team could then read the different layers of sediment "like a book," Druitt said.

"What you see is volcanic layers from all the eruptions that we knew on land," he said. "But then we go down to deeper levels before the volcano became emergent, when it was still submarine."

It’s in these deeper levels that researchers discovered the remnants of a 520,000-year-old eruption that was "bigger than anything else Santorini’s produced and probably one of the two biggest eruptions that the whole Hellenic volcanic arc has ever had," Druitt said.

Scientists examine sediment cores drilled up from the seabed in Santorini aboard the research ship.

The eruption ejected at least 21.6 cubic miles (90 cubic kilometers) of volcanic rock and ash, according to the study, published Jan. 15 in the journal Communications Earth & Environment. The Tonga eruption of 2022, by comparison, produced 1.4 cubic miles (6 cubic km) of debris.

"It’s a lot bigger — 15 times bigger — there, in the heart of Europe," Druitt said.

The discovery is big because it shows that the Hellenic volcanic arc is capable of producing tremendous underwater eruptions. "It gives us an example to study in detail of a very large version of Hunga-Tonga," Druitt said.

Santorini probably won’t see an eruption on this scale for another several hundred thousand years, Druitt said. The volcano last erupted in 1950, emitting lava that didn’t pose a significant threat.

However, the magma chamber "will continue to feed eruptions of lava and small explosive eruptions for the coming decades and maybe even centuries," Druitt said.

[I follow this German scientist. She comes up with good stuff. We need more scientists talking. Jan]

Here’s the video: https://www.youtube.com/watch?v=oWS48a3LmR0

Almost everyday, the number of confirmed exoplanet discoveries grows.

The majority of those planets, which sit just above 5,500 in total, have been identified by the Kepler space telescope. But for the last few years, NASA’s Transiting Exoplanet Survey Satellite (TESS) has been steadily adding new alien worlds to our growing planetary catalog of the cosmos.

Using a statistical method to comb through TESS’s large quantities of data on the night sky, a group of scientists led by Priyashkumar Mistry, a Ph.D. student at the University of New South Wales, have reported on the potential discovery of eight new exoplanets. What’s more, each one of these planets is considered to be a "super-Earth," a class of exoplanet that is larger than Earth but smaller than Neptune, according to NASA.

To date, TESS has confirmed almost 400 exoplanets, and yet another 6,977 await confirmation. The satellite observes nearby stars, waiting for dips, or fluctuations in the brightness of the stars. Such dips indicate to astronomers that something likely passed in between us and the star — and that something could be a new exoplanet.

"If this orbital motion ever comes between us and the star we will observe a dip in the brightness of that observed star. This is what we call a transit," Mistry told Space.com.

Mistry and his team used the Validation of Transiting Exoplanets using Statistical Tools (VaTEST) project to identify anomalies, which could indicate the presence of exoplanets, in TESS’s data.

Why do we need statistical tools?
It’s not only the case that these dips are caused by transiting exoplanets. Such false positives, which could include a star orbiting another star (binary system), or a background source, could generate a transit-like signal.

Mistry explains that the transit method can only provide the radius of an orbiting body. What if a planet sized star, such as a brown or red dwarf is in orbit? Astronomers would usually work out the mass of a transiting object using a method called radial velocity (RV), which is where an orbiting body exerts a gravitational pull on its home star. This results in the star doing a little dance, or ‘wobble’.

To detect the RV signal, though, it can take a lot of time observing just one star, especially if the exoplanet has a long orbital period — time and resources that the researchers didn’t have.

However, the VaTEST provided Mistry and his team with another means of confirming whether these transiting events were actually the result of orbiting exoplanets.

"The tool takes in the transit data and some inputs such as transit depth, period, TESS identifier, etc. Then based on that it starts fitting different models on the data and performs some probability calculations. And then finally it calculates False Positive Probability (FPP), if it turns out to be < 1% then we can validate that transit signal as a planetary transit," Mistry says.

The statistical tool calculated that eight such transiting events were likely caused by a class of exoplanet that astronomers call ‘super-Earths’ — and that six of them fall into the region known as ‘keystone planets,’ which have characteristics that help astronomers better understand the overall exoplanet population. This makes them highly attractive for further study.

What is a keystone planet?
To understand what astronomers mean by ‘keystone planet’, we first have to understand the radius valley concept. The radius valley reveals a scarcity of planets between 1.5 and 2 Earth radii, with orbital periods less than 100 days in the known population of exoplanets that orbit low-mass and sun-like stars. This radius range covers super-Earths, and another class of planet — sub-Neptunes, which are exoplanets with a smaller radius than Neptune.

Why does this scarcity exist? Some theories suggest this may be due to photoevaporation mass loss, where intense radiation from a home star could gradually strip away a planet’s atmosphere over time. This suggests that planets within this keystone region should be predominantly rocky, but observations are yet to confirm whether this is in fact the case.

"To understand this contradiction we need more and more keystone region planets. And that’s the reason why our validated exoplanets are interesting to study," explains Mistry. Adding more keystone planets to our exoplanet catalog, with the potential to do follow up observations with the James Webb Space Telescope (JWST), should help astronomers resolve what explanation best fits this mystery in the exoplanet data.

While super-Earth’s do have the name ‘Earth’ in their title, this doesn’t necessarily refer to their life-giving potential. Rather, life would likely find it hard to establish itself on any of the super-Earths discovered by Mistry and his team. The reason being the close proximity these planets have to their home stars.

"They are closer to their host star than Mercury is from the sun," says Mistry. This usually means they are tidally locked, where one side of the planet is forever facing the star, with the other side cloaked in eternal darkness. In this sense, it’s either scorching or freezing temperatures, neither of which are particularly life-friendly.

"But who knows. The cosmos is filled with so many surprises," Mistry quips.

A study of the eight super-Earths can be found on the preprint server arXiv, with the paper currently under review at the Publications of the Astronomical Society of Australia.

"That type of faulting can facilitate the exchange of surface and subsurface materials through shear heating processes, potentially creating environments conducive for the emergence of life."

Scientists are investigating specific geological features on the largest moons of both Jupiter and Saturn that could be ideal spots for the emergence of life elsewhere in the solar system.

The team, led by researchers from the University of Hawaii at Manoa, looked at what are called "strike-slip faults" on the Jovian moon, Ganymede — the solar system’s largest moon, bigger even than the planet Mercury — and Saturn’s moon, Titan. Faults like these happen when fault walls move past each other horizontally, either to the left or the right, with a famous example here on Earth being the San Andreas fault. It’s sort of like a giant crack, rift, or certain type of crevice in the ground.

Such seismic features are generated on these icy moons, scientists believe, when these bodies orbit their parent gas-giant planets. The planets’ immense gravitational influences generate tidal forces that squash and squeeze the moons, inevitably flexing the natural satellites’ surfaces. Plus, these tidal forces aren’t very consistent because the orbits of both moons are elliptical, meaning they are sometimes closer to Saturn or Jupiter. Other times, they’re much farther away. That, in turn, leads to even stronger tidal forces.

"We are interested in studying shear deformation on icy moons because that type of faulting can facilitate the exchange of surface and subsurface materials through shear heating processes, potentially creating environments conducive for the emergence of life," Liliane Burkhard, lead author of the research and a scientists at the Hawaii Institute of Geophysics and Planetology, said in a statement.

Saturn’s moon, Titan, has surface temperatures of around minus 290 degrees Fahrenheit (minus 179 degrees Celsius). This is incredibly cold — cold enough that the water of this moon actually plays the role of rock. It can crack, deform and, ultimately, form faults.

During its flybys of Titan, NASA’s Cassini spacecraft was able to determine that this moon of Saturn may have liquid water oceans tens of miles beneath its thick shell of ice. Additionally, Titan is the only solar system moon with a dense, Earth-like atmosphere, meaning it has a similar hydrological cycle with methane clouds, rain and liquid flowing across the surface to fill lakes and seas. For this reason, Titan is already considered one of just a few bodies in our solar system that could support life — as we know it, at least.

When the NASA Dragonfly mission (which launches in 2027) arrives at Titan in 2034, it will send a rotorcraft lander to fly across the frigid surface of this moon in an effort to hunt for those potential biological signs. That doesn’t exactly mean it’ll search for bug-eyed aliens, however. At the very least, the team hopes the lander will detect the chemical building blocks of life we’re familiar with.

The Dragonfly mission is initially set to land at the Selk crater area on Titan, a region that is also of interest to Burkhard and the team. This is because when calculating the stress exerted on Titan’s surface as a result of tidal forces, the researchers weren’t only focused on whether there might be signs of extraterrestrial life on the ground. They also explored the chance that the Selk crater region could be subjected to shear deformation to figure out whether it’s a safe landing site option for Dragonfly in the first place.

"While our prior research indicated that certain areas on Titan might currently undergo deformation due to tidal stresses, the Selk crater area would need to host very high pore fluid pressures and a low crustal coefficient of friction for shear failure, which seems improbable," said Burkhard. "Consequently, it’s safe to infer that Dragonfly won’t be landing in a strike-slip ditch!"

Three images show strike-slip faults at the San Andreas Fault (a) on Ganymede (b) and on Titan

Burkhard and colleagues also looked at the geology of the Jovian moon, Ganymede, to investigate the icy body’s history of tidal stress. In particular, the team looked at a bright region in the northwest of Ganymede called Philus Sulcus, which is composed of parallel sets of fractures.

The researchers basically looked at available high-resolution observations of the area to find that there were different degrees of tectonic deformation in bands of light terrain that cross over each other. The cross-cutting nature of these bands indicated to Burkhard and colleagues the existence of three distinct eras of geological activity — ancient, intermediate, and young.

"I investigated strike-slip faulting features in intermediate-aged terrain, and they correspond in slip direction to the predictions from modeling stresses of a higher past eccentricity," said Burkhard. "Ganymede could have undergone a period where its orbit was much more elliptical than it is today."

When investigating other parts of Philus Sulcus, the team found the direction of slip features to have different alignments. This implies these features may have been generated by processes other than high tidal stress. "So, Ganymede has had a tidal ‘midlife crisis,’ but its youngest ‘crisis’ remains enigmatic," Burkhard added.

The geologic investigations undertaken by this team and others are vital for informing the missions of spacecraft that aim to explore solar system moons like Titan and Ganymede. said Burkhard.

“Missions such as Dragonfly, Europa Clipper, and ESA’s JUICE will further constrain our modeling approach and can help pinpoint the most interesting locations for lander exploration and possibly for gaining access to the interior ocean of icy moons,” Burkhard concluded.

The team’s research is published across two papers in the journal Icarus.

[This is a first of a kind engineering breakthrough. How to make oxygen on Mars for humans! The results are good!! Clearly … humans on Mars … are coming. Jan]

NASA’s Perseverance rover has generated 4.3 ounces of breathable oxygen while on the Red Planet — enough to sustain an adult human for three hours.

In a first-of-its-kind experiment, NASA’s Perseverance rover has produced enough oxygen on Mars to keep an astronaut alive for three hours.

The rover, which first touched down on Mars in February 2021, produced the element using its Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) device — which generated the oxygen by converting carbon dioxide in periodic bouts over two years.

Since arriving on the Red Planet, the microwave-size device has generated 4.3 ounces (122 grams) of oxygen, according to NASA. This is equivalent to what a small dog breathes in 10 hours and gives scientists hope that human life could, one day, be sustained on the inhospitable planet.

"We’re proud to have supported a breakthrough technology like MOXIE that could turn local resources into useful products for future exploration missions," Trudy Kortes, director of technology demonstrations, Space Technology Mission Directorate (STMD) at NASA Headquarters in Washington, said in a statement. "By proving this technology in real-world conditions, we’ve come one step closer to a future in which astronauts ‘live off the land’ on the Red Planet."

Carbon dioxide is abundant on Mars, making up 95% of its thin atmosphere, according to NASA. By zapping small amounts of carbon dioxide over 16 experiments, the MOXIE device stripped oxygen atoms from CO2 and analyzed them for purity before sequestering them safely within a capsule. The leftovers were then emitted in the form of carbon monoxide.

The scientists say that oxygen extraction devices won’t just be useful for future colonists to breathe but for making rocket fuel too.

"MOXIE’s impressive performance shows that it is feasible to extract oxygen from Mars’ atmosphere — oxygen that could help supply breathable air or rocket propellant to future astronauts," Pamela Melroy, NASA’s deputy administrator, said in the statement. "Developing technologies that let us use resources on the Moon and Mars is critical to build a long-term lunar presence, create a robust lunar economy, and allow us to support an initial human exploration campaign to Mars."

Despite this small but significant step, many profound health challenges still stand in the way of a viable Mars colony. For starters, Mars is so cold that its average temperature of around minus 80 degrees Fahrenheit (minus 62 degrees Celsius) would freeze a human to death without a space suit, and its low atmospheric pressure would simultaneously boil their blood. This is without taking into account the bombardment of cancer-causing radiation from the lack of a protective ozone layer and the extreme losses to bone-density brought on by the journey there.

Until these problems are overcome, humanity’s closest view of the Red Planet is still from rovers such as Perseverance. As a key part of NASA’s $2.7 billion Mars 2020 mission, the robot, alongside the Curiosity rover, is searching for signs of ancient life on Mars’ surface by collecting dozens of rock samples for eventual return to Earth. The rover is accompanied by the Ingenuity helicopter, which has so far made 57 flights over the Martian surface.

The latest debate erupted within the field of archaeology Monday over the discovery of a roughly 3,000-year-old stone disk that appears to show a celestial map.

A giant stone disk, about the size of an average car tire, featuring what appears to be a celestial map, was discovered in northeastern Italy some years ago, according to a study published in the journal Astronomical Notes. The disks were found at the entrances to graveyards near two Protohistoric hill forts, believed to have been settled between 1800 and 1650 B.C.

Patterns carved into the stone were analyzed by researchers, and appear to line up with existing asterisms (star charts, or the placement of stars in our night skies). Of the 29 marks on the stones, nine line up with the Tail of Scorpius, five with Orion’s Belt, including Rigel and Betelgeuse, Pleiades and Cassiopeia. Twenty-eight of 29 of the marks line up with existing astronomy.

But there’s at least one mark that suggests a failed supernova event in our deep past, which is why we can’t see the same mark in the sky today.

But at least one astronomer is unconvinced by the work put forward by the researchers, according to Live Science. Griffith Observatory director Ed Krupp, who had nothing to do with the original research, thinks our ancient ancestors lined up their carvings on this stone disk accidentally.

“Could these marks represent asterisms? They could,” he said. But “does the paper argue a persuasive case? No, it doesn’t,” Krupp said, getting his 15 minutes of fame and contributing absolutely nothing of substance to the discussion. So why say anything at all? (RELATED: ‘100% Probability’ Major Global Catastrophe Destroys All Technology, Dennis Quaid Explains To Tucker Carlson)

My gut tells me that if we finally admit our ancestors were far more technologically savvy than we’ve given them credit for, we’ll have to start asking big scary questions about why we aren’t more developed as a species today. And if we really dig into why we’re going backward in our scientific exploration and social standing, a lot of very powerful people stand to lose all the control and money they’ve made from making our lives worse.

And we simply can’t have that, can we?

Astronomers have accidentally discovered the first known intergalactic trail of stars. The gigantic "stellar stream," which is around 10 times longer than the Milky Way, suggests that more of these structures could be lurking in deep space, a new study reveals.

Stellar streams are elongated threads of gravitationally entwined stars that have likely been ripped away from their parent galaxies or nebulas by the gravitational pull of other nearby galaxies. Scientists have mapped dozens of these streams within galaxies, including the Milky Way. But until now, none had been discovered in intergalactic space, meaning the space between galaxies.

In the study, which was published Nov. 30 in the journal Astronomy & Astrophysics, the researchers identified and mapped the first-ever intergalactic stellar stream, which stretches through the Coma Cluster, also known as Abell 1656, a group of more than 1,000 small galaxies located around 321 million light-years from Earth. The researchers named the first-of-its-kind structure the Giant Coma Stream — so named because it is also the largest stellar stream ever found.

"This giant stream crossed our path by coincidence," study lead author Javier Román, an astrophysicist at the Institute of Astrophysics of the Canary Islands, said in a statement. The team was initially studying halos of dispersed stars around the Coma Cluster, in an attempt to measure the dark matter that surrounds the galaxy group, when they came across the starry trail.

Study co-author R. Michael Rich, an astronomer at the University of California, Los Angeles, made the first observations of the Giant Coma Stream with his personal telescope. The team then turned to the more powerful William Herschel Telescope, located on La Palma in the Canary Islands, Spain, to properly study the stream.

The researchers were surprised to find the stellar stream lurking within the galaxy cluster. The structure is "a rather fragile structure amid a hostile environment of mutually attracting and repelling galaxies," study co-author Reynier Peletier, an astronomer at the University of Groningen in the Netherlands, said in the statement. Normally, you would expect something like this to be ripped apart by the more massive galaxies, he added.

The team is unsure how the stellar stream has persisted and grown so large, but one explanation could be the elusive material they were originally looking for — dark matter. While this mysterious entity makes up most of the matter in the universe, it is effectively invisible and can be detected only through its gravitational interactions with visible matter. It’s possible, the team said, that dark matter lurking within the galaxy group helped to stretch the stellar stream into its current shape.

The researchers are planning to study the stream with more powerful telescopes to learn more about the mysterious structure and its origins. They also hope to analyze individual stars within the stream to see if they are unique in any way.

The discovery of the Giant Coma Stream also opens the door for more intergalactic stellar streams to be found. The researchers believe there could be many more out there and hope that increasingly advanced telescopes, coupled with their findings, could help other astronomers find more of these stellar streams.
