New Michael Salla: Space Arks and the Arriving ET Seeders
New Michael Salla: Space Arks and the Arriving ET Seeders
This is a Short Film/Trailer for the upcoming April 9, 2022 Webinar: “ET Seeders, Space Arks and the Great Reveal”. Covers origins of ancient space arks used in past Earth catastrophes, the planetary evacuation of Mars, how the arks have been hidden throughout our solar system, how a plan for the Seeders to publicly emerge in the 1970s were sabotaged by a Luciferian alliance, how the arks are activating all over the Earth with the arrival of extraterrestrial Seeder races, and much more.
Jack Kirby was a skilled artist and storyteller who – with Marvel Comics’ Stan Lee – co-created such characters as the Incredible Hulk, the Avengers, and the Fantastic Four. But, it’s to a 1958 series that we have to turn our attentions.Its title was Race for the Moon, and it was solely the work of Jack Kirby. Race for the Moon was a trilogy, with part-2 titled “The Face on Mars.” It is focused upon the discovery on Mars – by U.S. astronauts – of a vast, carved human-like face on the surface of the so-called Red Planet. Kirby’s story would likely have fallen into obscurity, were it not for one, significant fact: in 1976, what appeared to be a huge, human-like face – cast out of rock – was photographed in a region of Mars called Cydonia. The late Mac Tonnies – the author of After the Martian Apocalypse – spent years addressing, and studying, the matter of what became known as a real-life Face on Mars.
Mac told me: “The first two objects to attract attention were the Face and the ‘D&M Pyramid,’ both unearthed by digital imaging specialists Vincent DiPietro and Gregory Molenaar. Their research was published in “Unusual Martian Surface Features”; shortly after, Richard Hoagland pointed out a collection of features near the Face which he termed the “City.” NASA itself discovered the Face and even showed it at a press conference after it had been photographed by the Viking mission in the 1970s. Of course, it was written off as a curiosity. Scientific analysis would have to await independent researchers.” He continued: “When NASA dismissed the Face as a ‘trick of light,’ they cited a second, disconfirming photo allegedly taken at a different sun-angle. This photo never existed. DiPietro and Molenaar had to dig through NASA archives to find a second image of the Face — and, far from disputing the face-like appearance, it strengthened the argument that the Face remained face-like from multiple viewing angles. The prevailing alternative to NASA’s geological explanation — that the Face and other formations are natural landforms — is that we’re seeing extremely ancient artificial structures built by an unknown civilization.”
Mac continued: “NASA chooses to ignore that there is a controversy, or at least a controversy in the scientific sense. Since making the Face public in the 1970s, NASA has made vague allusions to humans’ ability to ‘see faces’ (e.g. the ‘Man in the Moon’) and has made lofty dismissals, but it has yet to launch any sort of methodical study of the objects under investigation. Collectively, NASA frowns on the whole endeavor. Mainstream SETI theorists are equally hostile. Basically, the Face – if artificial – doesn’t fall into academically palatable models of how extraterrestrial intelligence will reveal itself, if it is in fact out there. Searching for radio signals is well and good, but scanning the surface of a neighboring planet for signs of prior occupation is met with a very carefully cultivated institutionalized scorn. And of course it doesn’t help that some of the proponents of the Face have indulged in more than a little baseless “investigation.”
“I think some of the objects in the Cydonia region of Mars are probably artificial,” said Mac. “And I think the only way this controversy will end is to send a manned mission. The features under investigation are extremely old and warrant on-site archaeological analysis. We’ve learned – painfully – that images from orbiting satellites won’t answer the fundamental questions raised by the Artificiality Hypothesis. I suspect that we’re seeing a fusion of natural geology and megascale engineering. For example, the Face is likely a modified natural mesa, not entirely unlike some rock sculptures on Earth but on a vastly larger and more technically challenging scale.” Given that the Face on Mars – regardless of what it is or isn’t – was not found and photographed until 1976, how is it possible that Jack Kirby was able to seemingly anticipate all of this back in the late 1950s? I don’t have an answer, but I do know there is another “Face on Mars.” It’s right below. Unless you view it as nothing stranger than a case of pareidolia.
Note: The photos above are from NASA. As NASA is a U.S. government agency, the pictures are in the public domain
Ever since we became aware that the universe extends past our planet and that space exists, people have looked to it as a final frontier. Humanity has made many great strides in our endeavors to conquer this last great unknown, but largely we have only really scratched the surface of getting there, with our progress of manned space missions still limited to the general vicinity of our planet. The desire to delve out into the cosmos is a powerful one, yet while most people may think that our true step towards space travel started in the 20th century, such aspirations have been around far longer than that. There have been serious plans put into space travel centuries before we even put the first animal in orbit, and one of these is certainly the time a 17th century scientist drew up his plans to reach the moon centuries before we actually did.
John Wilkins was born in Canons Ashby, Northamptonshire, England, on 1 January 1614, and was from a young age gifted with great intellect and a passion for the natural world. He would graduate from Magdalen College, Oxford, with a B.A. in 1631 and an M.A. in 1634, mostly focusing on theology, natural philosophy, and astronomy, all subjects in which he excelled. He then went on to be ordained as a priest in the Church of England, after which he took on various posts as chaplain to an array of the rich and powerful, including at one point Charles Louis, Prince Elector of the Palatine, and these posts would take him all over England and Germany, where he became acquainted with scholars from various fields. He would eventually in later years become Master of Trinity College, Cambridge, serve as Bishop of Chester, and go on to be one of the founding members of the Royal Society, which had him spending much of his time among some of the greatest thinkers, scientists, and intellectuals of his time. Yet for all of these achievements, he is perhaps most remembered for his groundbreaking ideas on space, space travel, and alien life that were well ahead of their time.
Wilkins was considered a bit of a genius himself, and during these years he had made many advancements in science and proposed many ideas that were extremely unique for their era. In his 1668 book, An Essay Towards a Real Character and a Philosophical Language, he proposed a universal language that could be used by scientists and travelers alike all over the world, and he also was a pioneer of the idea of using a universal system of weights and measure, as well as using pendulums to measure time and utilizing a universal measure of length. He was also an accomplished inventor, creating the first air gun, an artificial rainbow machine, a cypher and signal system that would allow one to “with privacy and speed communicate his thoughts to a friend at any distance,” and an inflatable bladder that would go on to serve as the prototype for the pneumatic tire, among others. Yet although these were all pursuits in which he was pushing new boundaries, it was space that truly fascinated him, and he spent most of his time looking up at the stars contemplating what was out there and how to get there.
John Wilkins
This was an era in which a cascade of discoveries in all areas of science was going on, and astronomy and our understanding of the universe was undergoing a bit of an upheaval. Johannes Kepler had worked out the physical laws governing how planets orbit the Sun. Galileo had completely changed our view of the stars and planets using the newly improved telescope to smash the long held idea of an Earth-centered view of the cosmos, and replace it with Copernicus’s heliocentric theory. We were now coming to an understanding that the stars and space itself extended farther than had ever been thought before. We also could finally see that the moon, which had long been an enigma, had a landscape in many ways similar to Earth, complete with mountains and plains. Humanity was suddenly thrown into a universe that was far more massive and stranger than had ever been thought before, and Wilkins was absolutely fascinated by this.
He would write two groundbreaking books on astronomy called The Discovery of a New World in 1638, and then in 1640 A Discourse Concerning a New Planet, in which he railed against the prevailing physics of Aristotle, which dated back 2000 years, and he introduced this new vision of the universe in plain English and clear vernacular terms that the average reader could understand, something very unique for its era. He also illustrated the idea that not only was Earth just one planet among many others, but that these other planets, as well as our own moon, might be inhabited as well. These were all ideas that had been doing the rounds for some time already, but of all of his ideas on space and the nature of the cosmos, his most bizarre and ambitious were his visionary notions of humans actually travelling to space to meet these beings for themselves. He would write of this:
In the first ages of the world the Islanders either thought themselves to be the onely dwellers upon the earth, or else if there were any other, yet they could not possibly conceive how they might have any commerce with them, being severed by the deepe and broad Sea. But the after-times found out the invention of ships, in which notwithstanding none but some bold daring men durst venture, there being few so resolute as to commit themselves unto the vaste Ocean, and yet now how easie a thing is this, even to a timorous and cowardly nature? So, perhaps, there may be some other meanes invented for a conveyance to the Moone, and though it may seeme a terrible and impossible thing ever to passe through the vaste spaces of the aire, yet no question there would bee some men who durst venture this as well as the other.
This was more than just a thought experiment for Wilkins, as he seriously believed that it was possible to fashion a craft to actually travel out into space, an idea which was mind-blowing for its time, the realm of wild, fanciful fiction. Inspired by such great explorers into the unknown as Columbus, Drake and Magellan, Wilkins truly believed that it was just the next logical step that we head past the horizon and into the new frontier of space. To do this, in around 1640 he proposed building a “flying chariot” that would be capable of reaching the moon, which he really felt was possible and which he really felt could be built.
In order to make this a reality, he had many ideas on how it could be accomplished. The first thing to do was to escape the pull of the planet, which was a bit of a challenge considering this was well before Isaac Newton had identified the force of gravity, but Wilkins thought he had it worked out. He believed that everything was held to the earth by a force of magnetism, but that if one could get just 20 miles into the air they would be free of this force, as the thinking at the time was that the power of gravity depended on the proportionate distance between objects, with the further apart they were, the weaker the force became. Wilkins reasoned that his could be done with a flying machine designed like a ship and equipped with a powerful spring, clockwork gears, gunpowder as a sort of propulsion system and internal engine, a vertical rotating sail sprouting from the backrest, wheels for when the thing landed, and a set of wings covered with feathers. This craft would then take off at a low angle, eerily predicting how planes would take off in modern times centuries before the Wright Brothers made their historic flight and in a time when inertia physics was scarcely understood.

Once in space, Wilkins suggested that the temperature might not necessarily be cold, and also explained that since the astronauts would be free from the magnetic pull of the planet, there would be nothing pulling on their digestive system to make them hungry and therefore they would not have any need for food in space. He similarly argued that astronauts would not have to worry about breathing either, as their lungs would get used to breathing the “pure air of angels” at that altitude. To him, flying across space would in a sense be even easier than flying on earth, and would merely be the next step past the ships used by the explorers of the past. He was under the impression, as was the common knowledge of the day, that Earth’s atmosphere was nearly identical to the conditions of space. All that needed to be done was to escape Earth’s attraction and we were set to make a journey to the moon that he estimated would take about 180 days, comparable to a long voyage across the oceans. Simple. He was sure his flying chariot would work, and said “I do seriously and upon good grounds affirm it possible to make a Flying Chariot; in which a man may sit and give such a Motion unto it as shall convey him through the air.”
Looking back at this with what we know now about flight and space travel, we understand that the whole plan is absurd and would have never worked at all, but at the time this was pretty visionary stuff. Although space travel and trips to the moon had been mentioned before in science fiction as pure fantasy, no one had ever seriously considered and drawn up plans for an actual working spaceship, and indeed this was an era in which the idea of real, actual space travel was not even really a thing. As the years went by and more discoveries were made, Wilkins himself would come to understand that travelling to the moon through his plan was not a possibility, although he did continue to experiment with various flying machines. Dr. Allan Chapman, a historian at Wadham College, Oxford, calls it the “Jacobean space programme,” and has said of the rise and fall of Wilkins’ grand vision:
His ingenuity was enormous. He saw his flying chariot as being the space version of Drake’s, Raleigh’s and Magellan’s ships. In the same way that it was an Englishman, Thomas Harriott, who beat Galileo in using the telescope, so on the anniversary of the landing on the Moon it was an Englishman who came up with the best argued possibility of getting to the Moon in his day. This was a honeymoon period of British science. The vacuum had not yet been discovered. In 1640, flying to the Moon was a heroic possibility. But by 1670, they realised it was impossible. They’d made so many discoveries in physics and astronomy in 30 years that they could see that flying to the Moon was not on. But in that glorious period around 1640, it seemed a real possibility.
Wilkins would go on to act as Bishop of Chester with a seat in the House of Lords in 1668, and continue his work in the Royal Society, as well as work as an educator all the way to his death in 1672. Although his ideas concerning space travel might seem extravagant, crude and silly by today’s standards, many of his basic ideas such as flying ships and long distance communication would eventually come true, things he was envisioning centuries earlier. During his era, he was a major influence and force in science, advancing the field and looking into the future frontiers of science, a visionary who may have failed in his quest in space, but holds a great legacy in science. He may not have ever reached the stars, but he was a consummate dreamer who encouraged others to dream too, and in many ways it is dreams that fuel our push into new realms of scientific discovery.
The year 1973 remains significant in the history of UFO studies for being a year where some of the most widely discussed and controversial incidents ever to have occurred were logged. From the alleged abductions of Charles Hickson and Calvin Parker at Pascagoula, Mississippi, to the famous “Coyne Incident” involving a near midair collision between a U.S. Air Force Huey helicopter and an oblong-shaped UFO, 1973 presented several incidents that remain among ufology’s best-known cases.
Nineteen-seventy-three was also the year that the phenomenon known as cattle mutilation began to rise into public awareness. However, a tangent subject that once received significant attention for its apparent relationship to the mutilation reports involves sightings of “mystery helicopters,” the origins of which remain undetermined.
“As mutilation reports exploded across the Midwest and West in 1975, the number of ‘mystery helicopter’ reports also increased in many areas,” read an entry by Scott H. Colborn in the Fortean Research Journal in 1989. “This helicopter/mutilation concurrence has continued throughout the past decade,” Colborn wrote. “We have concentrated much of our attention on the ‘mystery helicopters’ because we suspect that if we can acquire some concrete answers illuminating the role of these helicopters, we will be much closer to an understanding of the mutilation phenomena as a whole.”
According to Colborn, by the end of the 1980s, there were “well over 200 accounts of mystery helicopters near or at or in the vicinity of mutilation sites.” While he acknowledged that some of the reports had merely been “innocent flyovers” that were unrelated to the animal mutilations occurring nearby, there were nonetheless “too many reports of helicopters that harass herds of livestock, spotlighting cattle, chasing ground observers and even landing in pastures.”
More ominously, as Colborn noted, some of the incidents involved multiple helicopters numbering anywhere from five to seven of the aircraft all in the same vicinity. “People have been paced and chased down country roads. Deputies have pulled into pastures to watch unlit choppers rise and quickly fly away.”
In 1975, the cases involving purported “mystery helicopters” began to escalate, particularly in states like Colorado. According to Colborn, farmers in the eastern part of the state that year were so wary of the helicopter sightings that they were “ready to shoot down anything resembling a chopper,” resulting in a temporary grounding of all known and accounted-for helicopter flights in the region.
Elsewhere in New Mexico, the issue was similarly tense, and even led to the FAA launching a probe into the mystery helicopters. However, once a National Guard helicopter was stationed at the Clayton, New Mexico airport with instructions to chase any unidentified helicopters that were reported in the area, the sightings seemingly stopped for a time.
“We do not know the results of the FAA investigations,” Colborn wrote, “as they have since denied having any knowledge or information about it.”
“Perhaps they found a reason not to announce their findings,” he added.
Strange helicopters of unknown origin hadn’t been exclusive to the areas where cattle mutilations were occurring. During several incidents involving aerial incursions that occurred at U.S. Air Force missile launch sites along the northern tier during the mid-1970s, military personnel occasionally described seeing what appeared to be craft with lighting arrangements that most closely resembled helicopters, rather than exotic-looking aircraft.
In 1975, missile sites that included Loring, Wurtsmith, and Minot Air Force Bases on the nights or early mornings of October 27, 29, and 31, and again on the nights of November 7, 8, 9, and 19 were host to sightings of what many servicemen described as helicopters. However, after probing by The National Enquirer, an official U.S. Air Force response stated that the “helicopter assumption was based on the sound and light perceptions of the eyewitnesses,” and that there had been no overflights at these bases that the Air Force managed to identify as helicopters.
Strange helicopters were also reported during the famous Cash-Landrum UFO incident that occurred in December, 1980 near Daton, Texas. Witnesses Betty Cash and Vicky Landrum described seeing a large number of helicopters that appeared to pursue (or possibly escort away) a large, hovering diamond-shaped aircraft which produced hot jets of flame from its base. In the days and weeks following the sighting, the witnesses developed an array of medical conditions that they believed to have been related to the object they observed. Despite persistent inquiries made with the U.S. Air Force, the source of the helicopter sightings that coincided with Cash and Landrum’s observation of a UFO was never determined.
Some of the helicopters observed by Cash and Landrum in December, 1980, reportedly resembled the CH-47 Chinook with its distinctive twin-blade configuration

As to the possible origins of these mystery aircraft, Colborn presented several theories, which included:
1) The objects resembling helicopters were actually UFOs which merely resembled more conventional military aircraft (or were perhaps intentionally disguised to look like them) but instead shared a common origin with other more exotic craft.
2) The mystery helicopters might originate from some private, non governmental organization or agency, which might include a corporate or even a cult group. Other possibilities Colborn proposed were secret societies, paramilitary groups, or an “international cabal of industrialists, energy czars or similar manipulators.”
3) The helicopters might be part of a U.S. government group, which for clandestine reasons may have been involved in operations that included surveillance of high security installations, and even cattle mutilations, possibly as part of a “massive chemical-biological warfare (CBW) experiment.”
4) Alternatively, the mystery helicopters might have origins from within the U.S. government, but rather than playing an active role in the cattle mutilations, their purpose might have been part of a secret investigation of these incidents.
5) Another possibility is that rather than merely investigating cattle mutilations, the helicopters were being operated by an investigative group or agency within the U.S. government which had a much firmer grasp on the problem than the public does.
As Colborn proposed of this fifth possibility, this hypothetical U.S. government group could know “much more than ‘civilians’ do,” adding that the mystery helicopters “are of military origin” and that the government of theUnited States “possesses a very substantial amount of knowledge about the mutilators, their means and motives.”
“The government may be attempting to persuade mutilation investigators and the populace as a whole that perhaps the military might be behind at least some mutilations, a diversion away from the real truth,” according to Colborn, who noted the apparent presence of “implied a prior knowledge” in some cattle mutilation cases, “which enable the helicopters to arrive around the time of a mutilation.”
Even after the passing of several decades, the “mystery helicopters” of the 1970s and 80s remain mysterious. It seems hard to imagine that their presence represents anything but the clandestine efforts of one or more U.S. government agencies, although their proximity to UFO incidents, as well as overflights of high-security installations, and even apparent relationship to the ongoing cattle mutilation mystery also represents one of the more ominous unresolved questions about the modern UFO mystery.
The Dyatlov Pass incident happened in 1959, but the deaths of nine Russian hikers in the northern Ural Mountains under mysterious circumstances still baffles investigators and defies solution. From a violent wind to secret military testing to an avalanche to aliens to a KGB killing to a Yeti – the possible explanations have gone from the sublime to the ridiculous and many in-between. However, one has stood out … and this week a video was presented showing then strongest evidence yet that the Dyatlov Incident was caused by …
“The direct evidence from the Dyatlov Pass area obtained in those expeditions confirms that the region is avalanche prone and that slopes above the location where Igor Dyatlov and his group pitched their tent are steep enough for avalanches to release. Independent research by Russian snow and climate scientists supported assumptions and the main results of our slab avalanche modeling.”
The nine individuals who lost their lives at Dyatlov Pass in 1959.
Alexander Puzrin, a professor of geotechnical engineering at ETH Zurich, and Johan Gaume, head of the Snow and Avalanche Simulation Laboratory at Ecole Polytechnique Fédérale de Lausanne, have been the leading proponents of the slab avalanche cause since last year when their first paper on the subject was published in Communications Earth & Environment. Slab avalanches get their name from situations where a slab-like layer of snow pushed by winds forms on top of a weaker layer, causing pressure to be built up and small fractures to form – fractures that need only a small trigger – like a tent post being hammered – to release the slab to slid down a slope, even a not-so-steep one. In their new follow-up to that study, published in the same journal and in an article in Vice, Puzrin and Gaume describe three expeditions to the infamous location, including one just two months ago when professional mountain guides Oleg Demyanenko and Dmitriy Borisov witnessed and recorded video of slab avalanches.
“The initially favorable weather conditions quickly deteriorated, with wind and temperatures becoming similar to those on the night of the 1959 tragedy. Several times, the 300-kg snowmobiles and their drivers were overturned by wind gusts. Visibility became extremely poor. And then, when after a few failed attempts the two mountain guides approached their destination, the visibility briefly improved and revealed traces of two snow slab avalanches.”
Still photos of the videos are included in the study and shown in a documentary video, which is fortunate because
Demyanenko and Borisov watched as the evidence of the avalanches disappeared under snowfall less than an hour later. This explains why the Dyatlov rescue team could not find signs of an avalanche three weeks after the incident. It also shows why no one believes in slab avalanches … unless they see them for themselves. The study admits that the conditions were slighting different on February 1st, 1959.
“Nevertheless, the area is clearly avalanche prone, and the avalanche danger on the night of February 1st, 1959 was real.”
No avalanche is a good avalanche
Their first study concluded that the slab avalanche cause was “plausible.” Now, Puzrin and Gaume have visual evidence of similar slab avalanches causing similar destruction under similar circumstances with similar disappearances. They plan to continue building the case that the Dyatlov Group was killed by slab avalanches.
These are Star Dunes on Mars, Formed When the Wind Comes From Many Different Directions
These are Star Dunes on Mars, Formed When the Wind Comes From Many Different Directions
Missions to Mars are expensive, even orbiters. They’re there to do science, not take pretty pictures. But sometimes Mars’ beauty is captured inadvertently, usually with some science mixed in.
That’s the case with this picture of star dunes captured by the HiRISE camera on NASA’s Mars Reconnaissance Orbiter.
In most regions on Mars, winds blow in a prevailing direction. It’s the same here on Earth. So most dunes appear as waves, oriented perpendicularly to the wind direction. One common type of dune is Barchan dunes and they have two “horns” that face downwind.
Barchan Dunes are formed in prevailing winds. Image Credit: unknown. CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=571880
But star dunes are different. They form in winds that shift direction. They’re comparatively rare—on Earth, only about 8.5% of dunes are star dunes.
NASA’s Mars Reconnaissance Orbiter (MRO) has an almost-famous instrument called HiRISE – High-Resolution Imaging Science Experiment. Universe Today is full of HiRISE images. HiRISE wasn’t looking for star dunes when it captured this image in 2010. It was examining a crater in Mars’ Tyrrhena Terra region, looking at the geologic aspects of possible clays detected with the MRO’s CRISM instrument.
The happy accident shows how much geologic diversity Mars has on display.
Mars’s geologic diversity is stunning. The HiRISE camera does a great job of capturing that diversity, like in this image of star dunes in a crater in the Tyrrhena Terra. Image Credit: NASA/JPL/ UArizona
Star dunes are more common on Mars than they are on Earth because of all the impact craters. The wind swirls around crater rims and comes from many directions before it reaches the sand inside the dune. All that activity shapes the sand into a beautiful pattern.

Multiple Mysterious objects Sightings Over Las Vegas Leave Locals Confused
Las Vegas has always been a bit of a hot spot for UFO sightings, but over the past few weeks there has been more than the usual activity in the sky above Sin City. Recently, a homeowner captured what they say may be a fleet of Objects darting about in the Nevada sky.
The footage, reportedly captured on the homeowner’s doorbell camera, sped up for brevity one would assume, shows several bright objects appearing in the sky, moving very rapidly at times while staying completely still at others. The objects are flying really low and close the the tops of the houses,” he wrote. “Most public and military jets have rules that prevent them from flying this low, so I don’t think those are military jets.” Waring added, “It’s also a well known fact that in Las Vegas, is Nellis USAF base. And the US military gave an allotment of land to the TALL WHITES, a species of alien that lives to be 800 years old. They were given land behind the old firing range behind Nellis AFB. They used the land to create underground bases, where their UFOs do not inform the USAF of their comings and goings.” Two days later, on March 21, another video taken in Las Vegas purports to show another UFO flying in the sky above Trump Tower.
RIP Jordan Maxwell on Secret Societies, Ancient Symbolism and ETs - Coast to Coast Radio
RIP Jordan Maxwell on Secret Societies, Ancient Symbolism and ETs - Coast to Coast Radio
COAST TO COAST AM – Jordan Maxwell (1940 – 2022) Audio Tribute: Investigative reporter and author, Jordan Maxwell (1940 – 2022) interwove a variety of topics that included ufology, secret societies, ancient symbology, and occult religion. He suggested that many UFO witnesses are “marginalized” because the US government may have made a deal with ETs, in which they would put down reports and help the aliens stay incognito. Maxwell also mentioned that he had access to off-the-record video footage in which former astronaut Gordon Cooper revealed that he had worked with an ET whose ship had crashed in Mexico. Secret societies are a “powerful influence in the world today,” noted Maxwell, and yet some of the most hidden powerful people are actually “puppets of a higher power,” namely a group of ETs who co-mingle and exert control on the human family, he said.
Jordan Maxwell continues as a preeminent researcher and independent scholar in the field of occult/religious philosophy. His interest in these subjects began as far back as 1959. He served for three and a half years as the Religion Editor of Truth Seeker Magazine, America’s oldest Freethought Journal (since 1873). His work exploring the hidden foundations of Western religions and secret societies creates enthusiastic responses from audiences around the world.

An eyewitness in India took this 45 second video of crowds of people looking upward in astonishment at a UFO ring flying overhead. The object was a perfect circle and did not appear to be made of smoke. The craft is very high up and because it was cloaked, we could not see the body of the craft, however because of the overcast day and static electricity in the air, it creates a ring around the UFO that the aliens had not planed on happening. I'm sure the aliens were wondering how the hell the people below them were seeing them? You see, even aliens make mistakes.

Now I have long believed that ancient aliens had left signs for us to find on our own map. They left symbols to be found and one day interpreted to reveal to humanity that many intelligent alien species have been here and will come back. The symbols are often familiar shapes, even faces or like the Amazon river...entire sentences written in their own alien language and made...into a river! But...what does it say? Thats the important question that needs answering. This five star symbol (Pentagram) has a lot of different meaning on Earth. To different cultures it means different things. The five sided star has been the symbol of Jerusalem since 300BCE, its meant to symbolize justice, mercy and wisdom. This is 100% proof that ancient aliens left signs for us to find.

Jellyfish Life Form Passes Astronaut during Space Walk, March 23, 2022, Video, UFO Sighting News.
Date of sighting: March 23, 2022
Location of sighting: International Space Station
During a spacewalk a few days ago, a strange jellyfish like UFO passed by the astronauts. The object passes behind them and looks to have an aura all around it. It also has a lumpy shape, similar to that of a jellyfish. This is not a UFO so much as an entity. A living creature found only in space. Just as animals live underwater, there are creatures which can live in space. For instance, about ten years ago, Russian astronauts were cleaning the space station solar panels and found that there were huge plankton growing on the solar panels...thriving, eating, breading on the panels, using the suns energy. There was not one, but thousands and the Russians said they were bigger than normal plankton...so they sound very healthy to me. Thus...if one animal species could exist in space...its only stands to reason...there are others too.
The OLDEST Civilisation in the Americas: The Pyramid City of Caral, Peru | Ancient Architects
Not everybody knows that there is a magnificent lost pyramid city in the heart of Peru, a city that dates back to the same time at the Giza pyramids of Egypt. Yes, the magnificent ancient city of Caral dates back to 2,627 BC and is known as the Mother City of South America by some archaeologists.
For over a century archaeologists were searching for such a mother city and this large settlement, located 120 miles north of Lima, is one of the most ancient of the Americas, home of the Norte Chico civilisation. It was declared a UNESCO world heritage site back in 2009.
It was occupied between the 26th and 20th centuries BC and was described by excavators as the oldest urban centre in the Americas, but since its discovery in 1948, other ancient sites such as Bandurria in Peru have challenged this title.
Astonishingly, it was found in pristine condition and nothing had been built over it since the city was deserted. It would have been home to more than 3,000 people, with an elaborate complex of temples, an amphitheatre and ordinary houses covering 370 acres of land. There are plazas and residential buildings, and of course pyramids.
Watch this new Ancient Architects video to find out more about this truly fascinating lost civilisation, to see the incredible architecture, archaeological finds and the giant geoglyph associated with Caral.

NEW Scientific Mission to Explore the Great Pyramid of Egypt | Ancient Architects
We all remember the news from November 2017 when the ScanPyramids project announced the discovery of a Big Void inside the Great Pyramid of Egypt, located above the Grand Gallery and being either straight or inclined.
The news permeated the international media and I think everybody with an interest in Ancient Egypt was excited. It was the second major cavity located inside the pyramid using cosmic muon science.
Not long after the announcement of the big void, pictures were released of a robotic blimp that could be used to explore the void via an endoscopic camera, but now, nearly 5 years later, nothing has materialised. We still don’t know what the voids are or what’s inside.
Now, a new team of scientists plan to scan the Great Pyramid in what is called ‘The Exploring the Great Pyramid Mission’. They plan to field a very large muon telescope system that will be transformational with respect to the field of cosmic-ray muon imaging. The system will be 100 times more sensitive that the equipment that was used between 2015 and 2017.

Ancient Hall of Records found in Romania kept secret since 2003
Ancient Hall of Records found in Romania kept secret since 2003
In 2002, the Pentagon was running several military and geo desic programmes using satellites based on the above technology. The satellite spotted a particular structure located inside the Bucegi mountains.
In 2003, an amazing discovery was made of a large anomaly inside the Bucegi Mountains of Romania. A high level Italian Freemason was the first to alert a top secret paranormal unit of the Romanian intelligence service about the discovery made by US ground penetrating radar.
The discovery of a very large hemisphere or dome-shaped structure inside the mountain set off a complex set of geopolitical maneuvers that involved Romania being fast tracked into NATO for "its protection." All this happened around the same time a similar anomaly was found in Iraq making it an unknown factor in the US-led invasion.
Inside the mysterious structure was a fabulous repository of ancient information, a veritable Noah's ark of forgotten knowledge and genetics stored holographically. This ancient Hall of Records was built by a tall race of giants or human-looking extraterrestrials.
The Romanian "Hall of Records" has been involved in a complex geopolitical struggle between the Pentagon, Romanian government, and senior Freemasons vying to either release or suppress information coming out into the public arena.
There are 4 primary tunnels and further sub tunnels that lead to deeper and bigger places.
In these tunnels you will find rooms, huge rooms, with huge tables and stone chairs for people much taller than us. These rooms were created 50,000 years ago and each is connected to each other, protected by an energy source which activates all as one is activated.
The projection room contains all our history and can be replayed visually.
There are five tables on each side of the room. On some of them are different objects that appear to be technical tools. From many of them descending to the ground, are a lot of white, translucent wires which gather into rectangular boxes of shiny, silver material. The boxes are placed directly onto the ground. The cables are extremely flexible and lightweight and light pulses can be seen circulating along their length.
When approaching any of the tables, a holographic projection activates showing aspects of a particular scientific field. The three dimensional images are perfect and very large, with a height of almost two and a half meters.
The projections run by themselves but at the same time they are interactive and depend on one who interacts with the tables by touching their surfaces.
Climbing on a specially brought tripod the table surfaces can be seen. They are covered with a film of a dark glassy material. The film is divided into several large square bounded by straight lines, forming a kind of grid. At one table the subject is biology and the projected image are of plants and animals, some completely unknown.
Tapping one of the squares, the hologram shows the structure of the human body. It develops holographic images of various areas of the body that always rotate. Other squares show projections of other beings, on other celestial bodies. By tapping simultaneously two different squares, a complex scientific analysis shows the DNA of both beings and possibilities of compatibility between them.
In this interview, Peter Moon, famed author of the Montauk book series, discusses the Transylvania book series which he began editing and publishing in 2009. He explains how he first got involved through his time travel research on the Montauk Project. He has subsequently regularly traveled to Romania and been able to confirm key aspects of the story.
Strange UFO filmed over Kirtland AFB by the Air Force guy 2022
Strange UFO filmed over Kirtland AFB by the Air Force guy 2022
This strange unidentified flying object was seen and recorded in the sky above Kirtland Air Force Base in New Mexico on 7th January 2022.
Witness report:
Let me start this off by saying that I’m in the Air Force and I’m pretty knowledgeable in regards to what our aircraft look like. For example, I work on the 130’s here and they do not have red and white lights, let alone alternating strobe-like lights. In fact, to my understanding, most if not all airplanes today have red and green wingtip lights and typically don’t alternate in the fashion shown here. As far as the video goes, I saw this thing just hovering right above where our entry/exit gate is at, probably 7,000-8,000 ft up. It was not moving, and no sound was being generated at all(the video sound is just cars/wind).
After filming this, I walked to my car while glancing back at it occasionally. It was about a 45 second-1 minute walk to my car in the parking lot, and when I got to my car I pulled my phone out to take another video, but it was gone and I happened to glance over at the mountains to see one of the lights disappear. Mind you, that would’ve had to have been travelling well over 1,700 mph to reach those mountains in the time it took me to walk to me car.
Again, no noise, it was just hovering a few seconds prior, and the lights threw me off. This could very well be some crazy fighter that I’m not aware of. If anyone has any ideas please comment.
New Radio Images of Bizarre “Odd Radio Circles” Which are Vastly Bigger Than the Milky Way
New Radio Images of Bizarre “Odd Radio Circles” Which are Vastly Bigger Than the Milky Way
In radio astronomy, circle-shaped objects are fairly common. Since diffuse ionized gas often emits radio light, objects such as supernova remnants, planetary nebulae, and even star-forming regions can create circular arcs of diffuse gas. But in 2019 astronomers began to discover radio circles they couldn’t explain, in part because they are so large.
Known as Odd Radio Circles, or ORCs, they are roughly a million light-years across, which is about ten times wider than the Milky Way. Observations show that ORCs are centered around an elliptical galaxy, which suggests a galactic connection. It has been suggested that ORCs are formed by shock waves triggered by a powerful event such as a gamma-ray burst or fast radio burst, but given the size of ORCs, these events would need to have been triggered very far in the past. And shock waves can typically be seen in other wavelengths such as infrared and x-rays, but ORCs are only seen in radio light.
But a new study suggests other possible origins. Using the MeerKAT radio telescope, the team captured new data from one of the six confirmed ORCs, creating the highest resolution image so far. This revealed ring structures not previously seen. The team also measured the polarization of light from the ORC, which helped them narrow down possible causes.

Based on the observations, the light is consistent with that of synchrotron radiation. This occurs when charged particles are caught within a magnetic field. As the particles spiral along magnetic field lines, they emit a faint radio light. This often occurs with diffuse plasma, and it suggests a spherical shell gas was pushed away from the galaxy either through a rapid period of star production or the merger of supermassive black holes.
Another interesting possibility is that ORCs are formed by the galaxy’s supermassive black hole directly. Active galactic black holes, or active galactic nuclei (AGNs) as they are commonly known, often cause jets of material to stream away from the black hole at nearly the speed of light. Over time these can create vast radio lobes, where long-ejected plasma glows in radio light. One idea is that ORCs are caused by radio lobes oriented along our line of sight. Rather than seeing ejected plasma as a lobe, we would see it as glowing radio arcs.
While this study has narrowed down the possible explanations for ORCs, there isn’t one clear solution. But the team is undertaking further studies to look for more clues. And when future radio telescopes such as the Square Kilometer Array (SKA) are completed, were are bound to discover even more ORCs.
Astronomers See the Wreckage Where Planets Crashed Into Each Other in a Distant Star System
Astronomers See the Wreckage Where Planets Crashed Into Each Other in a Distant Star System
Our Solar System was born in chaos. Collisions shaped and built the Earth and the other planets, and even delivered the building blocks of life. Without things smashing into each other, we might not be here.
Thankfully, most of the collisions are in the past, and now our Solar System is a relatively calm place. But frequent collisions still occur in other younger solar systems, and astronomers can see the aftermath.
The aftermath of a collision is an opportunity to learn something about planet formation. When a collision between distant objects occurs, astronomers train their telescopes on it to figure out what happened. Astronomers used the Spitzer Space Telescope and other facilities to track the aftermath of a collision around a young star named HD 166191.
“By looking at dusty debris disks around young stars, we can essentially look back in time and see the processes that may have shaped our own solar system.”
Kate Su, study lead author, University of Arizona.
HD 166191 is a ten million-year-old star about 330 light-years from the Sun. It’s caught astronomers’ attention because it’s a protoplanetary disk transitioning to a debris disk. Years of observations showed a post-collision debris cloud passing in front of the star, giving scientists a novel look at collisions and their aftermath.
“By looking at dusty debris disks around young stars, we can essentially look back in time and see the processes that may have shaped our solar system,” Su said in a press release.
The team of astronomers started watching HD 166191 back in 2015. They observed the young solar system more than 100 times between 2015 and 2019. The system is too young to have fully-grown planets, but planetesimals and maybe even dwarf planets are bound to be orbiting the star. Unfortunately, they’re too small and distant to see in telescopes.
But planetesimals are the building blocks of planets. And those blocks don’t accrete in an orderly fashion. Instead, they crash into each other, sometimes shattering into smaller chunks, sometimes melding together to eventually form larger rocky planets.
Those collisions produce dust clouds that are visible in infrared. Energy from the star strikes the dust and emits infrared light. And that’s what the team saw in their observations with Spitzer. In 2018, the team observed a marked increase in brightness at HD 166191. The increase suggests that the amount of dust around the star increased dramatically. “The large-scale infrared brightening obviously points to a huge increase in the debris emission…” the authors write.”
Over the years, the researchers watched as a debris cloud from the collision transited in front of its star. They calculated the size of the objects that collided, when the collision occurred, and the speed of the impact. They also watched how quickly the debris cloud dispersed.
Their observations showed that the debris cloud was elongated. They also showed that the cloud was larger than the star, covering about three times more area. But the increase in infrared light in 2018 suggested something else. It indicated that only a small portion of the debris cloud passed directly in front of the star and that the dust cloud had to be much larger. According to their research, it had to cover an area hundreds of times larger than the star. That’s the only explanation for all that infrared light.
To produce that much dust, the objects in the collisions had to be as large as dwarf planets. The most well-known dwarf planet in our Solar System is Vesta, which NASA’s Dawn mission visited in 2011. The astronomers behind this study say that the objects that collided around HD 166191 were about the same size as Vesta, about 530 km (330 miles) in diameter. “The amount and rapidity of the increase in the infrared flux requires a catastrophic event, such as a collision between two large bodies (?500 km in diameter) occurring in the terrestrial zone,” the authors write in their paper.

The collision generated a lot of heat and some of the material was vapourized. Like balls on a pool table, the impact generated a chain-reaction of smaller collisions between debris and other orbiting rocky objects. The cascade of multiple collisions in mid-2018 explains the large amount of dust and the increase in infrared energy. “Simulations indicate a substantial rate of fragment collisions rapidly following the impact disruption of asteroid-sized bodies, which would expedite the initiation of an intense collisional cascade,” the paper states. “This intense activity is further highlighted by detecting a star-size dust clump, passing in front of the star, in the midst of its infrared brightening.”
Two things happened in the following months: the dust cloud expanded and became more translucent. The dust and the rocky debris from the collision were dispersing around the solar system. By the time 2019 rolled around, observations showed that the dust cloud that transited in front of the star was no longer visible, but the amount of dust in the system had doubled.
These observations are valuable to scientists who study solar systems and planets. Planet formation is largely hidden from view. Young solar systems are dusty places to begin with, and only certain observatories can pierce the veil of dust. Thanks to observatories like ALMA, we can see the lanes carved in the dust around young solar systems as planets form and sweep up the dust.

“Learning about the outcome of collisions in these systems, we may also get a better idea of how frequently rocky planets form around other stars,” said study lead author Kate Su.
Astronomers will keep watching HD 166191 to see how the system develops. Astronomers think that it’s transitioning from a protoplanetary disk to a debris disk. The star itself isn’t accreting any more material. The excessive infrared emissions suggest that the system is still dusty, but the star has dissipated much of the gas left over from star formation via photoevaporation.
“Theoretical simulations indicate that the very existence of terrestrial planets depends on the collisional merging of planetary embryos and oligarchs,” the paper says. This collisional merging generally happens during the first 200 million years after the protoplanetary disks have cleared out much of the remnant gas from the star formation. “Large-scale collisions among planetesimals and planetary embryos in the terrestrial-planet region are expected to be common after the dissipation of the gas in a protoplanetary disk, a stage we think HD 166191 is in,” the authors write.
In our Solar System there were probably dozens of Moon-sized to Mars-sized rocky bodies in the inner Solar System. Astronomers think that the Moon formed when a protoplanet named Theia collided with the Earth. There were probably many more collisions, and the architecture of the inner Solar System is the result of that process.
But astronomers are stuck playing forensics in our Solar System. They have to study distant systems like HD 166191 to see any of this occurring.
“The system’s evolutionary state (right after the dispersal of its gas-rich disk) makes it extremely valuable to learn about the process of terrestrial-planet formation and planetary architecture through future observations,” the paper explains.
What’s next for HD 166191? In their paper’s conclusion the authors write that “… we might be witnessing the early giant impact phase in assembling terrestrial planets in the inner zone.” Or the activity they’re seeing in the young system “… might be triggered by perturbation from nearby, unseen planet-mass objects, creating orbit-crossing collisions in the existing asteroid population.” Or the migration of a giant planet might be involved.
Young dusty systems undergo a lot of change, and only further observations will tell the tale. “The transient nature of extremely dusty systems further illustrates the importance of continuous monitoring. Future observations of this unique system would further shed light into our understanding of terrestrial-planet formation and overall assembling planetary architecture,” they conclude.
In 2014, the Japanese Space Agency JAXA launched the Hayabusa 2 spacecraft to visit asteroid Ryugu. It arrived at the asteroid in June 2018 and studied it from orbit for over a year. Hayabusa 2 even dispatched four rovers to the asteroid’s surface. After departing, it flew past Earth in December 2020, dropping off a sample of Ryugu.
Of all the scientific results from that impressive mission, the most interesting one might be this: Asteroid Ryugu might not be an asteroid. It might be the remnant of a comet.
The Hayabusa 2 mission showed that asteroid Ryugu is a rubble pile asteroid. Instead of being one large, monolithic chunk of rock, it’s a conglomeration of smaller rocks. Like some other asteroids, it’s shaped like a spinning top. The asteroid’s rapid rotation forged it into this shape.
The authors say that “A widely accepted formation scenario for Ryugu is a catastrophic collision between larger asteroids and the subsequent slow gravitational accumulation of collisional debris.”
Hayabusa 2’s Optical Navigation Camera-T captured this image of Ryugu from an altitude of about 64m. On September 21, 2018, it took the photo at around 13:04 JST. This is the highest resolution photograph obtained of the surface of Ryugu. Credit: JAXA
A lot of Hyabusa 2’s evidence supported the idea that Ryugu is an asteroid, which astronomers assumed was the case since its discovery in 1999. But one thing stood out among the evidence that didn’t fit with the asteroid definition: Ryugu has a high concentration of organic matter.
If Ryugu is a rubble pile asteroid created from the collision of two smaller asteroids, then why does it have so much concentrated organic matter?
That question is at the heart of a new study published in The Astronomical Journal Letters titled “The Asteroid 162173 Ryugu: a Cometary Origin.” The lead author is Associate Professor Hitoshi Miura of Nagoya City University.
In their paper, the authors say that not only might Ryugu be the remnant of a comet, but similar rubble-pile asteroids might also be former comets. Astronomers call these objects Comet Asteroid Transition (CAT) objects.
Comets form in the distant cold reaches of the Solar System. Unlike asteroids, which are all rock, comets are icy and contain rock and frozen volatiles. The volatiles are mostly water ice, but comets also contain frozen carbon dioxide, ammonia, methane, and carbon monoxide. Astronomers sometimes call them “dirty snowballs.” Comets also have an unbound atmosphere. When they approach the Sun, the warmth melts some volatiles creating the atmosphere, and they sublimate into space. The atmosphere contains dust as well as volatile gases.
But after passing close to the Sun many times, some comets have lost all their volatiles to space. What’s left is just rock. Those are sometimes called extinct comets.
This figure from the study shows how a comet can transition to an asteroid. (a) shows the comet nucleus containing water-ice and rock. (b) shows the ice sublimating from the outer layer as the comet enters the inner Solar System. (c) shows rocky debris accumulating on the surface and forming a porous mantle. (d) shows how the comet transforms into an asteroid after the remaining volatiles sublimate and escape through the porous mantle. Image Credit: Miura et al. 2022
If Ryugu is indeed a former comet, can that account for Ryugu’s characteristics?
Ryugu rotates rapidly, which could stem from its previous life as a comet. “Ice sublimation causes the comet’s nucleus to lose mass and shrink, which increases its speed of rotation,” said lead author Miura in a press release. “As a result of this spin-up, the cometary nucleus may acquire the rotational speed required to form a spinning-top shape.”
Asteroid Ryugu has a spinning-top shape due to its rotation. The rotation has shaped the asteroid over a long period of time, including creating the equatorial ridge called Ryujin Dorsum. Asteroid Bennu is also a spinning-top asteroid. Image Credit: By ISAS/JAXA, CC BY 4.0, https://commons.wikimedia.org/w/index.php?curid=87828813
According to Dr. Miura, the extinct comet hypothesis can also explain the high organic matter content. The organic molecules detected include CO, CO2, methanol, carbonyl sulphide, formaldehyde, formic acid, methane, and cyanate. “Additionally, the icy components of comets are thought to contain organic matter generated in the interstellar medium. These organic materials would be deposited on the rocky debris left behind as the ice sublimates.”
Comets like Ryugu have the same organics as carbonaceous chondrite asteroids, but they’re concentrated on the surface. “The local concentration may account for the extremely high organic content inferred from albedo,” the paper states.
The research team tested their hypothesis with numerical simulations. They calculated how long it would take for Ryugu to lose all its volatiles and become a rocky remnant. They also calculated the increase in rotational speed required to shape the asteroid into what it is today.
This figure from the study shows the results of the team’s numerical simulations. (a) shows the sizes of the initial cometary nucleus and the time required for it to diminish to Ryugu’s present size. (b) shows the spin-up of the cometary nucleus after shrinkage due to water ice sublimation. Image Credit: Miura et al. 2022.
“Our calculation suggests that Ryugu was once a comet and active for the first several 10 kyr and spent the rest of its dynamic lifetime as a rubble-pile asteroid,” the study says. “This scenario is consistent with the dynamical evolution of modern comets in the solar system.”
This study focuses on asteroids with three characteristics: spinning top-shaped, rubble-pile composition/morphology, and high concentration of organics. The results show that Ryugu and similar asteroids are comet-asteroid transition objects (CATs). “CATs are small objects that were once active comets but have become extinct and apparently indistinguishable from asteroids,” explains Dr. Miura. “Due to their similarities with both comets and asteroids, CATs could provide new insights into our solar system.”

Hayabusa 2 returned its Ryugu samples to Earth, and another mission will soon do the same. NASA’s OSIRIS-REx spacecraft visited asteroid Bennu, an asteroid very similar to Ryugu, and will return its samples to Earth in 2023. Analysis of these samples should confirm whether Ryugu and Bennu are asteroids or CATs.

“For there is nothing covered, that shall not be revealed; neither hid, that shall not be known.”
Atlantis is a fictional island mentioned in an allegory on the hubris of nations in Plato’s works Timaeus and Critias, wherein it represents the antagonist naval power that besieges “Ancient Athens”, the pseudo-historic embodiment of Plato’s ideal state in The Republic. In the story, Athens repels the Atlantean attack unlike any other nation of the known world, supposedly bearing witness to the superiority of Plato’s concept of a state. The story concludes with Atlantis falling out of favor with the deities and submerging into the Atlantic Ocean. Wikipedia
