Triangle UFO over the ocean in Mexico 22-Aug-2022

This interesting footage of a possible triangle UFO was filmed in the sky above the ocean near Rosarito Beach, a resort town on the coast of Mexico’s Baja California peninsula. This was filmed on 22nd August 2022.

Witness report: 

I initially took out my binoculars to see if the lights were coming from a tanker. I saw nothing below the lights, no form of a sea vessel. I know tankers have one red, green and red light always on, but none were observed. The lights stayed in formation and one by one disappeared. I took out my iPhone 11 to video the sighting, twice. One by one the lights would go out and then reappear at the same location.

‘Nog nooit Jupiter zo gezien’: James Webb-telescoop toont ongelooflijk uitzicht op planeet

De James Webb-telescoop, de nieuwste en grootste ruimtetelescoop, laat Jupiter zien als nooit tevoren. De telescoop legde de voorbije weken ongekende beelden vast van de gasreus met zowel manen als ringen, tot zelfs prachtige polaire nevel. “Het is allemaal heel ongelooflijk”.

  Bron: The Guardian, BBC, CNN

Verschillende beelden van de telescoop zijn samengevoegd tot een compositiefoto die de aarde een nieuwe blik gunt op de gasreus. “Zo kan je Jupiters Grote Rode Vlek zien rechts onderaan”, zegt wetenschapsexpert Martijn Peters, “Dat is een storm groot genoeg om de aarde te verzwelgen”. Martijn wijst ook op de vage ringen en verre sterrenstelsels die je kan zien op de achtergrond.

Rare “Red Sprites” Seen From ESO’s La Silla Observatory in Chile

This new image taken of the skies above Chile’s Atacama Desert near the European Southern Observatory’s (ESO) La Silla Observatory, shows bright red streaks in the sky known as red sprites. Red sprites are large-scale electrical discharges that occur high above thunderstorm clouds, usually triggered by the discharges of positive lightning between an underlying thundercloud and the ground. However, the red sprites appear high in Earth’s atmosphere, sometimes 50-90 km in altitude.

People have been telling folktales for centuries about mysterious red lights in the sky, which were usually dismissed by experts. According to the Farmer’s Almanac, even when respectable pilots or scientists (including CTR Wilson, a Nobel Prize winning physicist) described them, the scientific community ignored the events. However, in 1989, scientists from the University of Minnesota actually captured pictures of red sprites, and the attitude about them has since changed. While they now have been photographed and filmed thousands of time, — including by astronauts on the International Space Station — red sprites are still a fairly rare occurrence.

This new photo (lead image and below) from ESO almost looks like a painting. The red sprites appear low on the horizon, only due to the perspective of the camera, located on the platform of ESO’s 3.6m telescope at La Silla. The background of the photograph shows a green hue, known as airglow. ESO explained that during the day, sunlight knocks electrons away from nitrogen and oxygen in Earth’s atmosphere and, at night, these electrons recombine with the atoms and molecules, causing them to shine. Usually, airglow can only be seen in very dark skies where there is no light pollution.

Because of the remote location, with high altitude and lack of light pollution, La Silla is perfect for capturing these unusual phenomena.

This one is next level, and I know you haven't seen it before, since someone went to great lengths to have this video removed everywhere! 

This was sent to Dutchsinse in a package from Lt. Col Thomas Beardens company (which has now disappeared from the internet) after he passed away with the message "Dutch- don't know if you've seen THIS one" 

Needless to say, we've got a series of stories and explanations on Nikola Tesla from Lt. Col. Thomas Bearden that will absolutely floor you. 

He explains a new device that he made (Lt. Col. Bearden) on how to harness and use free energy using current electrical lines going into our houses and on power poles around the world. Amazing. 

Also amazing, the part about the French scientists and their work on curing certain diseases. As well as the part about transmitting "sicknesses", as well as transmitting cures.

Westminster, Colorado massive UFO sighting 20-Aug-2022

These UFOs were seen and recorded in the night sky above Westminster, a home rule municipality located in Adams and Jefferson counties, Colorado on 20th August 2022.

Witness report: 

My husband Josh was at the shopping center behind our house and called me to run outside and look up. I walked out and observed thousands of lights. They were silent and twinkling and multi colored. Please see attached videos, that I recorded. I have researched the SpaceX images, and those lights are a straight line and white. These were all over the place. Some much farther away than the others. The lights were about 10,000 feet above. There were no lantern festivals.

Mysterious Alien Signals Found to Repeat on a Regular 16-Day Cycle

There's something in deep space that is sending out a signal to Earth in a continuous sixteen-day cycle.

We’ve just found out that a series of complex alien signals coming from space are not as random as we initially thought. A new study revealed an FRB source located around half a billion light-years from Earth pulses, ominously, on a regular and consistent 16-day cycle.

Is this the ultimate alien message we’ve been waiting for? According to experts, a mysterious alien signal has been found to repeat on a sixteen-day cycle cautiously.

Fast Radio Bursts are among the most mysterious cosmic phenomenon discovered in the twenty-first century. We’ve only started to study and understand the signals and are still trying to figure out what causes them and their exact source.

Some have suggested FRBs are a natural, cosmic phenomenon, while others have dared to say that FRBs could be the ultimate alien evidence we have all been looking for.

VICE recently reported a new study led by Cornell University scientists had identified a strange Fast Radio Bursts located approximately half-a-billion light-years from Earth. This strange alien signal has been found to pulse regularly in a 16-day cycle.

This means that Cornell University scientists have revealed that it is the first FRB discovered on a repeating schedule.

“We conclude that this is the first detected periodicity of any kind in an FRB source,” the team revealed in a paper published on the preprint server arXiv in late January.

“The discovery of a 16.35-day periodicity in a repeating FRB source is an important clue to the nature of this object.”

Between September of 2018 and October of 1029. the researchers have studied as many as 28 FRBs that have been identified by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project (CHIME/FRB), a state-of-the-art radio telescope located in British Columbia, Canada.

Although the repeating signal is as strange as it gets, it doesn’t necessarily mean its aliens. However, there are a few theories that could explain what causes the repeating cycle.

One explanation is that the signal could originate from an orbiting object, which only sends out a signal at a certain point in the orbit. Another theory is that the repeating cycle originates from a binary star comprised of a massive star and a highly magnetized star.

Another option, as revealed by VICE, is that if the FRB source is orbiting a compact object, like a Black Hole, then it might flash signals towards Earth only at a certain point in the orbital period.

Interestingly, a group of astronomers recently tracked down this particular FRB to a galaxy dubbed  SDSS J015800.28+654253.0. Although it is located half a billion light-years from Earth and may seem behemoth distance, the signal dubbed FRB 180916.J0158+65 is the closest Fast Radio Burst ever detected by astronomers.

Despite knowing where it is, we have absolutely no idea what it is.

Congress implies UFOs have non-human origins

In Congress, where legislation is drafted, debated and enacted, clear and concise definitions are of paramount importance. As military aircrews increasingly encounter unidentified flying objects (UFOs), lawmakers recently made several striking revisions to the definition of “UFO.” Key among them: The explosive implication that some UFOs have non-human origins.

As first reported by researcher Douglas Johnson, a draft bill approved unanimously by the Senate Select Committee on Intelligence rebrands UFOs as “unidentified aerospace-undersea phenomena.” Expanding the definition to include objects in space and under the oceans significantly broadens the scope of a muscular new office tasked by Congress with investigating UFOs.

The revised definition of “UFO” also includes “transmedium” objects which, according to lawmakers, “transition between space and the atmosphere, or between the atmosphere and bodies of water.”

In short, members of a key national security-focused committee believe that objects of unknown origin are demonstrating remarkably advanced technology by moving seamlessly between space, air and water. A report accompanying the legislation notes that “transmedium threats to United States national security are expanding exponentially.”

It strains credulity to believe that lawmakers would include such extraordinary language in public legislation without compelling evidence. Perhaps members have seen the classified sensor data that prompted former President Trump’s director of national intelligence to state that UFOs exhibit “technologies that we don’t have [and] that we are not capable of defending against” (among several other eyebrow-raising comments).

Most strikingly, Congress’s new definition of “UFO” excludes “man-made” objects.

Over the last seven decades, most UFO sightings involved “man-made” objects, such as misidentified aircraft, balloons, satellites or drones. Yet now, according to Congress, “man-made” objects “should not be considered under the definition as unidentified aerospace-undersea phenomena.”

Moreover, in a congressional directive, objects identified by the new UFO office “as man-made…will be passed to appropriate [Department of Defense and Intelligence Community] offices” for further analysis.

Congress, in short, is forcing the government to focus on objects that are not “man-made.”

Imagine that the new UFO office identifies a highly advanced drone flying in sensitive airspace. Under the draft legislation, regardless of the drone’s origin – be it Chinese, Russian or otherwise – the UFO office must immediately stop investigating and hand the case over to another government entity.

This implies that members of the Senate Intelligence Committee believe (on a unanimous, bipartisan basis) that some UFOs have non-human origins. After all, why would Congress establish and task a powerful new office with investigating non-“man-made” UFOs if such objects did not exist?

Make no mistake: One branch of the American government implying that UFOs have non-human origins is an explosive development.

It is also part of a remarkable shift in official attitudes towards UFOs.

In the late 1940s and early 1950s, many senior government officials believed that UFOs had “interplanetary” origins. But a series of still-unexplained encounters in the summer of 1952 sparked Cold War national security fears among defense and intelligence agencies. As a result, the U.S. government initiated a campaign to “debunk” and discredit all UFO sightings, no matter how credible. For decades, officials mocked any suggestion that UFOs had extraterrestrial origins.

Not anymore.

In discussions and interviews, NASA administrator Bill Nelson suggested that UFOs encountered by military aircrews in recent years have otherworldly origins. (NASA, it should be noted, is proceeding “full force” on an unprecedented scientific study of UFOs.)

Former CIA Director John Brennan stated that UFOs might “constitute a different form of life.” According to James Woolsey, a fellow ex-CIA director, “something is going on that is surprising to…experienced pilots.”

As Top Gun-trained aviators remain convinced that they observed objects “not of this world,” director of national intelligence Avril Haines – America’s top spy – has not ruled out extraterrestrial origins for UFOs.

Moreover, former President Clinton refers reflexively to the high likelihood of otherworldly life in the universe when asked about UFOs. For his part, former President Obama speculated openly about contact with extraterrestrial life when asked about recent military UFO encounters.

After the customary giggles and smirks that still accompany any mention of “UFO” died down, both Clinton and Obama adopted a serious, matter-of-fact demeanor when discussing the topic. Clinton, in particular, scolded a television audience for laughing when a host asked him about UFOs. Of note, former presidents continue receiving the government’s most sensitive intelligence briefings.

Unsurprisingly, this remarkable shift in attitudes towards UFOs is fostering a broader, richer discussion of the phenomenon.

Comedian and political commentator Bill Maher, for example, recently theorized that UFOs are intentionally revealing themselves to fighter pilots.

He may be on to something. The geometrically reconstructed flight path of a well-known 2015 UFO encounter off the U.S. East Coast indicates that the object reacted as a Navy fighter jet attempted to sneak up behind it. Importantly, the object’s movement did not suggest hostility as much as a desire to be observed by the aircrew, which ultimately “flew right up to the thing.”

A UFO involved in the now famous 2004 “Tic Tac” incidents appeared on radar at the precise location of a rendezvous point known only to a small group of aviators and radar operators. Ten years later, two fighter jets nearly collided with a UFO hovering at the exact location and altitude of an entrance point to a military training range.

To Maher’s point, some UFOs appear to move and position themselves in ways that make their presence obvious to nearby military aircrews.

With Congress openly suggesting that UFOs have non-human origins, this behavior is particularly intriguing.

The idea that agencies of government, the military and the intelligence communities of our world are actively, and secretly, monitoring alien abductees is startling. However, it's not at all outlandish. And nor is it paranoia-driven. In fact, quite the opposite is the case. There is something else, too. It's a highly controversial question: Is it possible that some UFO / alien abduction cases are really the secret creations of government / MK-Ultra type agencies? It may very well be the case. Consider the following from July 1997: an example of a case of alleged alien abduction that appears to have been part of a sophisticated military-controlled mind-control operation is described by Alison, a woman from Arizona, who lives on a ranch not too far from the town of Sedona. From the age of twenty-seven to thirty-one, Alison was subjected to at least five kidnappings that bore all the hallmarks of the classic alien abduction scenario. On each occasion, she was in her living-room, either reading or watching TV, when her two pet dogs – Lucy and Summer – began to act in a distressed fashion, pacing around the room and whimpering.

At that point, things always became a blur, and Alison would later find herself in a different part of the house with several hours of time having passed. She would always awake feel groggy, and with a pounding headache and dry mouth. For days after the weird experiences, she would dream of the moment when things would begin to go awry – which always resulted in a complete loss of electricity inside the house, a deep humming noise emanating from outside the large living-room window, and powerful and intensely bright lights enveloping the room. In her semi-conscious state, Alison would see small shadowy figures scuttling around the room. They would then carry her outside onto a small craft where she was subjected to a gynecological examination and some form of nasal probing. She would then be returned to another part of the house and the aliens would leave. It was only after the aliens had departed that the intense humming noise would cease.

On what Alison believes to have been the fifth abduction, however – July 27, 1997 - the mysterious humming sound abruptly came to a sudden halt, only a few seconds after her cosmic visitors had entered the room. At that point, Alison recalled – significantly, not in a later dream on this occasion but in real time – she began to slowly regain her senses. And, very surprisingly, so did the aliens. In their place was not a group of frail-looking bald-headed, black-eyed “Grays,” but a number of large and burly men wearing what looked like suspiciously like black military fatigues – and who quickly exited Alison’s home. This begs an important question: how many more UFO / abduction events may have been secretly staged by the military? Now, onto another outrageous, but plausible, situation of the mind-control type.

It all went down on the night of October 10, 1973. On the night in question, two men – Charles Hickson and Calvin Parker – were fishing on the banks of Mississippi’s Pascagoula River. That is, until approximately 9:00 p.m. rolled around. Parker and Hickson suddenly noticed a light in the distance. It was following the river and appeared to be coming in their direction. As the light got closer, they could see it was actually a brightly lit, somewhat egg-shaped craft, from which came a deep, throbbing hum. Such was the intensity of the hum, it provoked intense nausea in both men. Confusion quickly followed. The pair watched in horror and amazement as what was described as a “hatch” opened and a trio of very strange-looking creatures exited the hovering object. Even stranger, the three things floated from the craft, across the waters of the river, and towards Hickson and Parker.

This particular breed of E.T. was described as humanoid, with mask-like faces, and heads from which three carrot-style points protruded. On top of that, they had large crab-like or lobster-like claws.    When the things from another world were practically on top of terrified Parker and Hickson, both men were rendered into a state of paralysis. Suddenly, the entities seized the pair, who were manhandled onto the UFO. Like most abductees, Hickson and Parker were quickly reduced to the equivalents of lab rats. When the trauma-filled encounter was over, the pair was dumped back on the edge of the river. There is, however, something else.

In the latter stages of the Second World War, the U.S. military used Horn Island, Mississippi, as a place where top secret, biological-warfare research could be undertaken. Matters were brought to an end when the Second World War was over. The official line is that research in the area was cancelled. There are, however, local tales of covert operations and experiments into mind-manipulation in the region as late as the early 1970s. Could Charles Hickson and Calvin Parker have been mind-meddled by something akin to the 1950s MK-Ultra programs - but much more sophisticated? I say: "Yes."

Ready to see one of the most famous alleged alien abduction incidents questioned? It’s coming, anyway. It’s that of Betty and Barney Hill. They were a husband and wife who, on the night of September 19, 1961, and while driving home from Canada to New Hampshire after completing a fun vacation, had a significant number of hours erased from their minds. It all happened near Indian Head, New Hampshire. It was there they saw a strange light in the sky that appeared to be carefully shadowing them from above. Concern and anxiety set in, which is no surprise. Finally, they made it home. Something very strange and disturbing happened to the Hills, but such was the state of their minds, they weren’t sure what it was. But, they certainly wanted to know. 

One of those who came to believe that the Hills had been subjected to an MK-Ultra-type encounter was the late Philip Coppens. He said: “It is clear that the Hills were being monitored by USAF [U.S. Air Force] Intelligence before the encounter took place, through Major James MacDonald, who had befriended them some time earlier. Betty Hill wrote to [UFO researcher / author] Donald Keyhoe who, despite the fact that he received over a hundred letters a day, homed in on this initially unremarkable case. Within twenty-four hours, Keyhoe had arranged for the Hills to be visited by top-level scientists, including C.D. Jackson, who had previously (definitely not coincidentally) worked on psychological warfare techniques for President Eisenhower [italics mine]. Stretching coincidence far beyond breaking point, Jackson already knew Major MacDonald, with whom he next interviewed the Hills.” Philip continued on: “It seems that Betty and Barney Hill were at the center of a web that involved USAF Intelligence and top military experts in psychological warfare. The evidence suggests that the Hills were the subjects – victims – of a psychological experiment [italics mine]. ”Now, let us have a look at a bizarre affair from the 1950s and that went down in Brazil.

it all concerned the almost-over-the-top tale of a young Brazilian man. His name was Antonio Villas Boas. He worked on his family’s farm at the time, but, went on to become a well-respected attorney. It was on February 22, 1958 that Villas Boas prepared for Dr. Olavo Fontes a remarkable document. Fontes, at the time, was a respected gastroenterologist at the National School of Medicine in Rio de Janeiro and a highly dedicated Flying Saucer investigator. That document told of his, Villas Boas’, close encounter with an alien on October 15, 1957. But, this was no sterile “take me to your leader”-style experience involving bug-eyed, spindly creatures. Nope. According to the then-twenty-three-year-old farmer, he went where, quite possibly, no man had ever gone before. That is, after being forcibly taken on-board a UFO by very human-like beings. Villas Boas proudly told Fontes that he did nothing less than get it on with a hot E.T. babe from the great and mysterious beyond. Or, that’s what certain people engaged in sophisticated mind-manipulation operations wanted Villas Boas and Fontes to think occurred.

For many Flying Saucer seekers now in their sixties, seventies and eighties – and who grew up with the case - the Villas Boas incident still remains a classic of its time. It’s a story that is not to be, ahem, fucked with. The fact is, though, that when we address the case carefully, we do see a body of solid data that suggests the alien encounter was actually nothing of the sort. Let’s take a look at the “UFO” that Villas Boas was taken aboard in his drugged-out state. Nedelcovic claimed it was really a military helicopter. There are very good reasons as to why we should go with Nedelcovic’s claims. If you take a careful look at what Villas Boas had to say about the craft he found himself on-board, you’ll see what I mean. Villas Boas said the craft was shaped “like a large elongated egg.” He described it further, stating that “on the upper part of the machine there was something which was revolving at great speed and also giving off a powerful reddish light.”

When the vehicle left the scene, said Villas Boas, it moved “slowly into the air until it had reached a height of some 30 to 50 meters…The whirring noise of the air being displaced became much more intense and the revolving dish began to turn at a fearful speed…At that moment, the machine suddenly changed direction, with an abrupt movement, making a louder noise, a sort of beat.” Contrary to what has been said, Villas Boas was never taken on-board a Flying Saucer-shaped craft. Villas Boas’ own words demonstrate that. On top of that same machine was something that was “revolving at great speed.” Rotor-blades? What else? Nothing, that’s what. Then, there was the noise coming from the craft: “a sort of beat.” You certainly don’t have to be an aviation expert to realize that Villas Boas, even in his druggy state, had seen – and had been taken on – a helicopter. And, not on a UFO. Or, a Flying Saucer, as they were termed way back then.

Much the same could be said about the near-legendary Rendlesham Forest "UFO landing" of December 1980. In my book on the case, The Rendlesham Forest UFO Conspiracy: A Close Encounter Exposed as a Top Secret Government  Experiment, I wrote the following promo ad: "In the final days of December 1980, strange encounters and bizarre incidents occurred in the heart of Rendlesham Forest, Suffolk, England. Based upon their personal encounters, many of the military personnel who were present at the time believed that something extraterrestrial came down in those dark woods. What if, however, there was another explanation for what happened four decades ago? What if that explanation, if revealed, proved to be even more controversial than the theory that aliens arrived from a faraway world? The ramifications for the field of Ufology would be immense. In his new, sensational book, Nick Redfern reveals that one of the most famous UFO cases of all time was really a series of top secret experiments using holograms, mind-control programs, deception, disinformation, conspiracies and cover-ups. The shocking truth of a 40-year-old mystery is now revealed."

The reason for all of this weirdness? It's simple: to test new mind-altering technology. And to hide that same technology behind a huge UFO banner. If you think that such a thing could never happen, just read this article again and let the story sink into you. The whole scenario that I have laid out is far more likely than a situation involving black-eyed, little aliens from faraway worlds. Yes, I know that might destroy the cherished belief-systems of many people in Ufology. However, when it comes to the heart of the alien abduction issue, we must go where the facts take us, rather than where the the cool stories go.

Spain's Stonehenge revealed: Prehistoric circle of 150 stones 2,000 years older than Britain's famed monument emerges from the depths of a reservoir after drought causes water to drop to a quarter of its usual level

• Spanish Stonehenge, first discovered in 1924, sits below the surface of the Valdecañas Reservoir
• An intense drought plaguing Spain drained the reservoir to just 28 percent capacity, revealing the stone circle for just the fifth time
• The monument consists of 150 standing granite stones, some more than six feet tall, which was constructed more than 7,000 years ago  - at least 2,000 years before Stonehenge 
• Experts fear it will be destroyed if submerged again for a prolonged time and are petitioning the government to have it moved to a new location 

By STACY LIBERATORE FOR DAILYMAIL.COM and REUTERS

A prehistoric circle of 150 standing stones dubbed the Spanish Stonehenge has re-emerged from a reservoir for the only the fifth time since its discovery after the worst drought in 60 years left the waterbody at a quarter of its usual level.

The Dolmen of Guadalperal, a circle of granite stones dating from 5,000 BC, in the Valdecañas Reservoir in central Spain has only been seen four times since it was discovered in 1924. Nearly 20 years later, in 1963, the valley was deliberately flooded on the order of the Spanish dictator Franco, only emerging at periods of intense drought in the following years. 

The stones, which are at least 2,000 years older than Stonehenge in England, have wavy details that are believed to represent the nearby Tagus River. Some theories suggest the prehistoric structure was either used as a solar temple or laid over tombs when it was built by Celtic people 7,000 years ago.

It is not as famous as Stonehenge in England, but the theories to their purposes are similar - the monument in Wiltshire is also thought to serve as an ancient solar calendar.

The Spanish Stonehenge stones could disappear completely if they endure another prolonged submersion because the granite rocks are prone to erosion.

The Dolmen of Guadalperal, a circle of granite stones dating from 5,000 BC, in Spain's Valdecañas Reservoir has re-emerged for the only the fifth time since its discovery after the worst drought in 60 years left the waterbody at a quarter of its usual level

The standing granite stones - some as tall as 6ft - were discovered in 1924. Nearly 20 years later, in 1963, the valley was deliberately flooded on the order of the Spanish dictator Franco, only emerging at periods of intense drought in the following years

Similar to Stonehenge in England, theories suggest the so-called Spanish Stonehenge was used as a solar temple or laid over tombs when it was built by Celtic people more than 7,000 years ago

Archaeologists fear the stones could disappear completely if they endure another prolonged submersion, because the granite rocks are prone to erosion

The site was thought to be condemned to the history books in the 1960s when a Spanish general ordered the construction of a hydroelectric dam in Peraleda de la Mata, near Cáceres in Extremadura

Ángel Castaño, president of the Peraleda Cultural Association, recently started a petition to move the prehistoric monument out of its watery location and to somewhere it will survive. 

The monoliths are already showing significant signs of wear, Castaño said in 2019 when the stones were last above water, and if they are not saved now, it may be too late. 

Not much is known about Spanish Stonehenge because it typically sits at the bottom of the 14,108 square-mile deep reservoir, however the recent rise of the stones could let archeologists finally unravel its ancient secrets.

'It's a surprise, it's a rare opportunity to be able to access it,' said archaeologist Enrique Cedillo from Madrid's Complutense University, one of the experts racing to study the circle before it gets submerged again. 

The site was discovered by Hugo Obermaier, a German priest and amateur archaeologist, in 1925.

In 1963, Francisco Franco Bahamonde, who ruled over Spain from 1939 to 1975, ordered the valley boarding the Tagus river to be flooded and this area included the stone circle.

But before its rediscovery and subsequent demise, it is thought the stones would have centered around a central chamber for sun worship.

Dolmens are vertically arranged stones usually supporting a flat boulder.

When the reservoir is filled (pictured), the Stonehenge is submerged and impossible to see or visit  

Although there are many scattered across Western Europe, little is known about who erected them. Human remains found in or near many have led to an often-cited theory that they are tombs.

Local historical and tourism associations have advocated moving the Guadalperal stones to a museum or elsewhere on dry land.

Their presence is also good news for Ruben Argentas, who owns a small boat tours business. 'The dolmen emerges and the dolmen tourism begins,' he told Reuters after a busy day spent shuttling tourists to the site and back.

However, more than 80,000 tourists flock to England's Stonehenge each year to see a circle of enormous rocks that are up to 30 feet high, dwarfing the six-foot tall single monoliths uncovered in Spain. 

The stones have wavy details that are believed to represent the nearby Tagus River, which is the longest river in the Iberian Peninsula

Spain's circle is made up of 150 granite  stones, with some standing six feet tall. Experts fear another prolonged submersion could destroy the prehistoric monument 

Radiocarbon dating of the rocks found they range in age from around 7,000 years old, which is about 2,000 years older than Stonehenge

There are more stones at the Spanish site. Stonehenge has only has 93.

However, Stonehenge's monument covers 10,800 square feet, making it a far bigger area than the Spanish site that is only 16 feet in diameter.

Radiocarbon dating of the rocks found they range in age from around 7,000 years old, which is about 2,000 years older than Stonehenge.

Neolithic people, often prone to building monolithic structures, emerged throughout time across Europe.

It is widely accepted Stonehenge's bluestones were quarried from Preseli Hills in Wales and moved to the current location, but how the idea for Stonehenge arrived on British shores remains a mystery. 

Archaeologists have uncovered Roman remains at Dolmen of Guadalperal, along with other artifacts like coins, ceramic fragments and a grinding stone, along with an entire settlement nearby. 

Although the structure was used for religious purposes, experts say it also had an economic purpose by acting as a trading hub. 

There are hundreds of stone circles similar to Stonehenge in other European countries. 

To erect a just one of the massive stones, people had to dig a large hole with a sloping side. The back of the hole was lined with a row of wooden stakes. The stone was then moved into position and pulled to the upright position using plant fiber ropes and likely a wooden frame for support.

Spain's Stonehenge is not as famous as the monument in England (pictured), but the theories to their purposes are similar -the are both believed to have served as ancient solar calendars

The recent appearance allows visitors and researchers to get up close to the stones. Archaeologists hope to learn more about who built the structure and why 

The Stonehenge monument standing today was the final stage of a four part building project that ended 3,500 years ago

Stonehenge is one of the most prominent prehistoric monuments in Britain. The Stonehenge that can be seen today is the final stage that was completed about 3,500 years ago. 

According to the monument's website, Stonehenge was built in four stages:   

First stage: The first version of Stonehenge was a large earthwork or Henge, comprising a ditch, bank and the Aubrey holes, all probably built around 3100 BC. 

The Aubrey  holes are round pits in the chalk, about one metre (3.3 feet) wide and deep, with steep sides and flat bottoms. 

Stonehenge (pictured) is one of the most prominent prehistoric monuments in Britain

They form a circle about 86.6 metres (284 feet) in diameter. 

Excavations revealed cremated human bones in some of the chalk filling, but the holes themselves were likely not made to be used as graves, but as part of a religious ceremony.

After this first stage, Stonehenge was abandoned and left untouched for more than 1,000 years. 

Second stage: The second and most dramatic stage of Stonehenge started around 2150 years BC, when about 82 bluestones from the Preseli mountains in south-west Wales were transported to the site. It's thought that the stones, some of which weigh four tonnes each, were dragged on rollers and sledges to the waters at Milford Haven, where they were loaded onto rafts.

They were carried on water along the south coast of Wales and up the rivers Avon and Frome, before being dragged overland again near Warminster and Wiltshire.

The final stage of the journey was mainly by water, down the river Wylye to Salisbury, then the Salisbury Avon to west Amesbury. 

The journey spanned nearly 240 miles, and once at the site, the stones were set up in the centre to form an incomplete double circle. 

During the same period, the original entrance was widened and a pair of Heel Stones were erected. The nearer part of the Avenue, connecting Stonehenge with the River Avon, was built aligned with the midsummer sunrise. 

Third stage: The third stage of Stonehenge, which took place about 2000 years BC, saw the arrival of the sarsen stones (a type of sandstone), which were larger than the bluestones.

They were likely brought from the Marlborough Downs (40 kilometres, or 25 miles, north of Stonehenge). 

The largest of the sarsen stones transported to Stonehenge weighs 50 tonnes, and transportation by water would not have been possible, so it's suspected that they were transported using sledges and ropes. 

Calculations have shown that it would have taken 500 men using leather ropes to pull one stone, with an extra 100 men needed to lay the rollers in front of the sledge.

These stones were arranged in an outer circle with a continuous run of lintels - horizontal supports. 

Inside the circle, five trilithons - structures consisting of two upright stones and a third across the top as a lintel - were placed in a horseshoe arrangement, which can still be seen today. 

Final stage: The fourth and final stage took place just after 1500 years BC, when the smaller bluestones were rearranged in the horseshoe and circle that can be seen today.

The original number of stones in the bluestone circle was probably around 60, but these have since been removed or broken up. Some remain as stumps below ground level.

A recent report looked at the impact of climate change on Bigfoot, the Loch Ness monster and other cryptids whose potentially hidden existence could finally be revealed as global warming drives them north to colder climates (Bigfoot), droughts shrink their lakes and rivers (Loch Ness monster), and cutbacks in farming shrink their food sources (Chupacabra). That same climate change is affecting paleontology, as the melting permafrost reveals more frozen carcasses in Siberia, and archeology, as lakes and rivers recede to free bodies (Lake Mead) and lost towns. It is that last consequence that has allowed an ancient megalith known as the Spanish Stonehenge to emerge from a reservoir and remind the world that England is not the only country with stone circles and mysterious monuments. And, while the appearance of the ancient monolith is good for archeology and local tourism, it could be bad for the granite stones themselves.

"It's a surprise, it's a rare opportunity to be able to access it."

That sentiment expressed by archaeologist Enrique Cedillo from Madrid's Complutense University to Reuters is shared by many, but they shouldn’t be surprised because humans are the reason why the Dolmen of Guadalperal, also known as the treasure of Guadalperal, disappeared in the first place. Located in Peraleda de la Mata, a town in the region of Campo Arañuelo in eastern Extremadura on the west coast of Spain bordering Portugal. The standing stones were first discovered in 1926 by German archaeologist Hugo Obermaier on the Guadalperal estate where he was a frequent summer guest.

After the end of World War I, Obermaier moved to Spain to focus on the many Neolithic sites in that country. Shortly before finding the stones, he had worked in the Cave of Altamira (a cave filled with prehistoric rock art) and studied Neolithic rock engravings of south Oran in Algeria. On the Guadalperal estate, Obermaier uncovered 140 standing stones in an oval shape with a diameter of 5 meters (16.4 feet). He determined that the stones were dolmen – funerary megaliths or single-chamber megalithic tombs that generally consisted of two or more vertical stones supporting one flat capstone. (Current photos here.) 

The dolmen of Guadalperal, also known as the Spanish Stonehenge, is seen due to the receding waters of the Valdecanas reservoir in the outskirts of El Gordo, Spain, August 3, 2022.

Most dolmen date from the early Neolithic (4000–3000 BCE) and are often covered with earth to form a burial mound. Because of their age and unsteadiness, the capstones are usually found on the ground. That appears to be how Obermaier found the Dolmen of Guadalperal, which he dated to between 2000 and 3000 BCE. Many of the stones were engraved and Obermaier and his team made reproductions of them, which were published in 1960. This was fortunate, as we will soon see.  

In addition to the standing stones, Obermaier found Roman artifacts -- a coin, ceramic fragments and a grinding stone – inside the oval, and 11 axes, ceramics, flint knives and other relics nearby. Also uncovered in the area was the remains of settlement, dating to the same time as the stones, which included houses, charcoal, pottery, mills, and sharpening stones, lending credence to the theory that the occupants were the builders of the dolmens. The total collection makes this Spanish Stonehenge an important historical site that should be worthy of protection. Unfortunately, progress overcame archeology in this case.

In 1963, Spain’s dictatorial leader Francisco Franco approved the building of the Valdecañas reservoir – the floor of the massive project included the site of the Dolmen of Guadalperal. At the time, archeologists decided that moving the stones would ruin their historical significance and opted to let the location be flooded as a way to preserve it. Thus, the Dolmen of Guadalperal were not seen again … until 2019 when a severe drought reduced the level of the Valdecañas reservoir to a point where the Spanish Stonehenge could be seen in a NASA satellite image. Eventually, most of the stones emerged, but the rains soon returned and the stones sunk back to their hiding place.

"It is a megalithic dolmen of great value that is now, for the first time, and who knows if it will be the last, fully accessible."

The Raíces de Peraleda Association launched a Change.org petition at the time to raise money to do something to save the Dolmen. They pointed out that the stones showed clear signs of deterioration as the porous granite cracks and crumbles. In addition, the waters have eroded the engravings and many are no longer visible – showing how fortunate it was that Obermaier's team made reproductions of them.

“It currently sits fully exposed in one corner of the Valdecanas reservoir, in the central province of Caceres, where authorities say the water level has dropped to 28% of capacity.”

It is now 2022 and Europe is in the midst of a record-breaking drought. Spain and Portugal have implemented restrictions on water usage because reservoirs like the Valdecañas are drying up. While that is bad news for farmers, businesses and anyone who drinks water, it is good news for the Dolmen of Guadalperal, the archeologists waiting to study them and unlock their mysterious origin, and the preservations who hope this will give them enough time to get the approvals and support to finally move the stones or figure out a way to protect them. If they need some incentive to convince local officials of the benefit to saving the Dolman, it comes from Ruben Argentas, who owns a small boat tours business.

"The dolmen emerges and the dolmen tourism begins."

Sadly, this is turning out to be a zero-sum problem. While local businesses are taking advantage of increased profits due to archeological tourism, the local farmers have no water for crops or livestock. With the reservoir down by nearly a third of its normal level, it will take a lot of rain over a long season to recover – and the dry conditions now make the ground hard for absorption and set the stage for damaging floods. For those who believe in karma, it appears payback is finally happening for the dictatorship of Francisco Franco.

As of this writing, no decisions have been made concerning the future of the Dolmen of Guadalperal. Let’s hope the important historical structures can be saved. It’s too bad Franco isn’t around to get his karma payback.

LATEST UFO SIGHTINGS AND VIDEOS

'Something in our skies' | Ex-Pentagon official discusses UFO sightings in Canada, U.S.

Joy Malbon speaks with Luis Elizondo, a ex-Pentagon official, who resigned in 2017 and went public about the agency's UAP program.

Are UFOs real? South Korean, U.S. scientists analyse

UFO sightings have frequent and continuous in recent years, according to a naval intelligence officer in the United States. Unidentified Flying Objects have long been a topic that has never failed to fascinate people and provoke debate on whether these mysterious apparitions are real or not.
There have certainly been testimonies but has the evidence over the years proven concrete?
We delve into the issue of Unidentified Flying Objects with Avi LOEB, Frank B. Baird Jr. Professor of Science of Harvard University, Sunglyul Maeng , Professor of Electrical & Electronic Engineering at Woosuk University.

Q1. Professor Loeb: It's been 50 years since congress last held a hearing on mysterious objects in the skies, are we now confident enough to say UFOs and aliens exist? Has it finally been confirmed by the hearing?

Q2. Professor Meng: Have you found any interesting remarks made at the Congressional UFO hearings?

Q3. Professor Loeb: These are the first hearings since the Air Force terminated Project Blue Book in 1969. What could be the reason to hold an open forum now, after decades of internal investigations and research?

Q4. Professor Loeb: Nowadays there's been a switch from using the term UFO to “UAP", or unidentified aerial phenonemon. How are UFOs and UAPs different in the sense of their implication?

Q5 Maeng: Now there are so many questions surrounding USOs which have largely gone unanswered. What has been made known so far?

Q6. Loeb: The Pentagon has so far confirmed that there were 11 near misses with UFOs by the U.S. military. Has there been any contact towards or from them so far?

Q7. Maeng: Many UFO witnesses speak of the unusual movement of UFOs, such as a rapid direction change or unbelievably high speed, as if they defy the limits of physics. As a scientist, what makes you think this is not human technology?

Q8. Professor Maeng:I know that you have researched UFOs for 30 years in Korea. Were there any UFOs observed by south Korean Air Force pilots?

Q9. Professor Loeb: It seems we have a long way to go until we get the answer to the ultimate question: do aliens exist?
What actions are further needed from government?

Avi LOEB, Frank B. Baird Jr. Professor of Science of Harvard University, Sunglyul Maeng , Professor of Electrical & Electronic Engineering at Woosuk University. Thank you for your time.

Several mission concepts are currently on the table. In 2008, NASA’s Glenn Research Center began studying a possible sample-return mission known as the “Hall” concept. This New Frontiers-class concept would perform a sample-return from Phobos and Deimos. In January 2013, scientists from Standford University, the Massachusetts Institute of Technology (MIT), and NASA’s Jet Propulsion Laboratory began collaborating on a new Phobos Surveyor mission. The mission is currently in the testing phases with a potential launch window of 2023 and 2033.

In March 2014, NASA proposed a Discovery-class mission called Phobos And Deimos & Mars Environment (PADME), which would place an orbiter in Mars orbit by 2021 to study Phobos and Deimos. A heritage concept called OSIRIS-REx 2 is being considered that would use parts from the first OSIRIS-REx mission (a sample-return mission to the asteroid Bennu) and conduct a sample-return mission from Phobos and Deimos. Beyond NASA, other space agencies also hope to send robotic spacecraft to explore the Martain satellites.

In 2015, the Japanese Aerospace Exploration (JAXA) unveiled their concept for a sample-return mission to Phobos known as the Martian Moons Exploration (MMX). This mission would conduct a Deimos flyby before landing on Phobos multiple times to obtain samples – similar to what the Hayabusa2 mission did on asteroid Ryugu. This mission is international in scope, with NASA and the ESA contributing, and is currently scheduled to launch in 2024 and return samples to Earth five years later.

Russia plans to repeat its previous attempt to send a sample-return mission to Phobos named Fobos-Grunt (Russian for “Phobos Ground”) in the late 2020s. In 2015, the ESA began assessing a sample-return mission to Phobos called Phootprint, which was planned for launch by 2024. This mission was originally conceived as a collaborative effort between the ESA and Roscosmos, which have since terminated their cooperation agreements due to Russia’s invasion of Ukraine.

From all these proposals, it is clear that multiple space agencies intend to explore the Moons of Mars in the near future. The origin and subsequent evolution of these moons are considered part of a wider effort to explore and characterize Mars. In the meantime, the debate continues!

How Weak Will Astronauts Feel When They First set Foot on Mars After Months in Space?

In the coming decade, in 2033, NASA and China intend to send astronauts to Mars for the first time in history. This presents numerous challenges, ranging from logistical and technical issues to ensuring that astronauts can deal with waste and have enough food and water for the months-long transit to and from Mars. But of course, there’s also the health and safety of the astronauts, who will be spending months traveling through space where they’ll be exposed to cosmic radiation and microgravity. There are even concerns that after months of exposure to microgravity, astronauts will have trouble adapting to Martian gravity.

To determine if these fears have merit, a team of space medicine experts from the Australian National University (ANU) developed a mathematical model to predict whether astronauts can safely travel to Mars and perform their duties once they arrive on the Red Planet. This model could be immensely valuable alongside all the other preparations that need to happen before astronauts set foot on Mars. It could also be used to assess the impact of short- and long-duration missions that take astronauts far beyond Low Earth Orbit (LEO) and the Earth-Moon system in the future.

The paper that describes their mathematical model and conclusions recently appeared in npj Microgravity, a scientific journal published by Nature. The research team was led by Dr. Lex van Loon, a Research Fellow from the ANU College of Health and Medicine (CHM). As he and his colleagues note in their study, the potential hazards for missions bound for Mars are numerous, but the greatest threat is arguably the time the astronauts will spend in microgravity. Combined with damaging radiation from the Sun and cosmic sources, the experience will cause fundamental changes to their bodies.

Based on extensive research conducted aboard the International Space Station (ISS), microgravity is known to cause muscle and bone density loss and affect organ function, eyesight, and the cardiopulmonary system – the heart and its ability to pump blood through the body’s system of arteries and veins. As Van Loon described in an ANU news release, their research is not only essential because of proposed missions to Mars, but for the burgeoning commercial space sector as well:

“We know it takes about six to seven months to travel to Mars and this could cause the structure of your blood vessels or the strength of your heart to change due to the weightlessness experienced as a result of zero gravity space travel. With the rise of commercial space flight agencies like Space X and Blue Origin, there’s more room for rich but not necessarily healthy people to go into space, so we want to use mathematical models to predict whether someone is fit to fly to Mars.”

Co-author Dr. Emma Tucker, an astrophysicist and emergency medicine registrar, added that prolonged exposure to zero gravity could cause the heart to become lazy because it doesn’t have to work as hard to overcome gravity and pump blood throughout the body.  

“When you’re on Earth, gravity is pulling fluid to the bottom half of our body, which is why some people find their legs begin to swell up toward the end of the day. But when you go into space that gravitational pull disappears, which means the fluid shifts to the top half of your body and that triggers a response that fools the body into thinking there’s too much fluid. As a result, you start going to the toilet a lot, you start getting rid of extra fluid, you don’t feel thirsty and you don’t drink as much, which means you become dehydrated in space.

This, says Tucker, is why astronauts returning from the ISS are seen fainting when they set foot on Earth again or need to be transported using wheelchairs. The longer they stay in space, the more likely they will collapse when they return to Earth, and the more difficult the process of readjusting to Earth’s gravity. In the case of the NASA Twins Study, Mark Kelly spent over a year in orbit and experienced terrible pain, swelling, and other symptoms upon his return (as he described in his book Endurance: A Year in Space, a Lifetime of Discovery).

When it comes to missions bound for Mars, there’s the added complication imposed by the communications delay between Earth and Mars. Depending on the alignment of the Sun, Earth, and Mars, these delays can last as long as 20 minutes, which means astronauts must be able to perform their duties without immediate assistance from mission controllers or support crews (which includes medical emergencies). As Van Loon explained:

“If an astronaut faints when they first step out of the spacecraft or if there’s a medical emergency, they’ll be nobody on Mars to help them. This is why we must be absolutely certain the astronaut is fit to fly and can adapt to Mars’ gravitational field. They must be able to operate effectively and efficiently with minimal support during those crucial first few minutes.” 

Their model relies on a machine learning algorithm based on astronaut data collected from past Expeditions aboard the ISS and the Apollo missions to simulate the risks associated with traveling to Mars. Testing showed that it could simulate key cardiovascular hemodynamic changes after prolonged spaceflight and under different gravitational and fluid loading conditions. And the results are encouraging, as they indicate that astronauts can function after months spent in microgravity.

While the current model is informed by data derived from middle-aged and well-trained astronauts, the researchers hope to expand its capabilities to include commercial spaceflight data. Ultimately, their goal is to create a model that can simulate the impact of prolonged space travel on relatively unhealthy individuals with pre-existing heart conditions (in other words, untrained civilians). They hope this model will provide a more holistic picture of what would happen if an “everyday” person were to travel to space.

Further refinements could be made to incorporate age-related health issues, which would make sense given the number of celebrities that have flown to space recently (Wally Funk, William Shatner, Laura Shepard, Richard Branson, etc.). Who knows? Perhaps it will be possible to simulate the effects of long-term exposure to microgravity on children and fetal development. This research is crucial if we ever want to send humans to the Moon, Mars, and other destinations to live someday.

Mars and Moon Dust can be Turned Into Geopolymer Cement. Good Enough for Landing Pads and Other Structures

Materials science has long taken the lead in space exploration research, and it seems to have been getting even more attention than usual lately. That is especially true for building materials. NASA has funded several new research programs to develop new building materials that can do everything from providing structure to future human habs to landing pads for future reusable rocket missions. Now that second goal is one step closer, thanks to researchers at the University of Delaware.  

Their recent paper in Advances in Space Research describes a method for making a type of geopolymer out of Martian and lunar regolith simulants. Geopolymers are an advanced form of concrete that has enhanced physical properties such as compressive strength and thermal tolerance – precisely the type of properties you want to be stronger if you’re trying to build a retro rocket landing pad.

Landing a rocket on another planet (or moon, for that matter) is risky. Dust and rocks blown skyward by the downdraft of the column of flame the rocket emits could damage the rocket itself or anything that it might be carrying, such as humans. The best way to stop that potential hazard would be to build a landing pad. However, one made with regular concrete can’t withstand a rocket blast without breaking itself into the kind of chunks most dangerous to rockets. That is where geopolymers come in.

With their extreme physical and thermal properties, they are ideally suited to serve as the landing pad material for rockets. The only problem is – how do you make them off of Earth? That was the focus of the team in Delaware.

They used Martian and lunar regolith simulates as a basis for making the geopolymer, which was created using a combination of clay and a solvent with a high pH – in this case, sodium silicate. After mixing the two materials, the researchers let the resulting mixture cure for seven days before testing the new material’s properties.

Under Earth-like conditions, the materials they created had the kind of properties they were looking for. However, Maritan conditions were not as congenial. At -80 C, the reaction to form the geopolymer hardly happened at all. Additionally, in a vacuum, which is also the natural state of the moon or Mars, the formation didn’t happen as well as it did under ambient Earth conditions.

Two solutions present themselves – either future space explorers could use a system that heats up and pressurizes the extraterrestrial clay so that the reaction would happen as expected. Or further material advances could point to potential solutions that could be done at ambient temperatures on the Moon and Mars. Either way would require more research.

But there’s not only work on the material science side – sodium silicate isn’t particularly common on Mars. It would require hundreds to thousands of kilograms of the stuff to make enough geopolymer for even a single landing pad, which is expensive if launching it from Earth, though it could be done with a single rocket payload. In addition, more recent research just reported that clays might not be as common as initially thought on Mars, making the other material component of the geopolymer harder to find as well.

Either way, explorers will eventually need a landing pad to ensure their descending (or ascending) rocket isn’t blasted into shrapnel by fast-moving rocks. And geopolymers seem as good a solution as any offered so far. Material science keeps marching forward, and someone someday will find a long-term solution.

On August 20, 2022 the solar satellite SDO AIA 304 captured something huge that arrives between the solar satellite and the sun, partially obscures the sun, it slowly going down and back up. 

It doesn't look like a partial solar eclipse, it's something moving between the camera and the sun. 

Directly after the massive black object disappears, an anomaly passing the sun. 

But what could this huge black object be?
