It’s probably nothing: Gravitational wave burst detected near Betelgeuse
It’s probably nothing: Gravitational wave burst detected near Betelgeuse
Betelgeuse has dimmed recently, prompting some to wonder if it’s about to explode. An explosion might trigger a gravitational wave burst. Betelgeuse is still there. The nearby gravitational wave burst probably means nothing for this star. Still …
Gravitational waves are “ripples” in space-time caused by some of the most violent and energetic processes in the universe.
The Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo detectors recorded a “burst” of gravitational waves this week, from an area of sky near the red supergiant Betelgeuse. This unanticipated burst has been dubbed, for now, S200114f. It’s prompting some interesting chatter on Twitter because Betelgeuse has undergone an unusual dimming in recent weeks, and some astronomy enthusiasts have wondered if it were about to explode. Betelgeuse has not exploded. It’s still there. Still, a supernova explosion of Betelgeuse might be linked with a gravitational wave burst.
The gravitational waves we’ve detected so far usually relate to extreme cosmic events, like two black holes colliding or neutron stars finally merging after being caught in a death spiral. Burst gravitational waves have not been detected before and scientists hypothesize they may be linked to phenomena such as supernova or gamma ray bursts, producing a tiny ‘pop’ when detected by the observatories.
Astronomer Andy Howell at Las Cumbres Observatory leads a group that studies supernovae and dark energy. He posted some especially informative tweets about Betelgeuse last night.
New gravitational-wave candidate?https://gracedb.ligo.org/superevents/S200114f/view/ …#S20014 was found by an unmodelled burst search, I'm always skeptical of these, as they are easily confused with glitches False alarm rate: 1 per 25 yr Rating:
For the record, I do know that it can take hours for the shock to reach the surface. I didn't point that out initially because I didn't want people staying up all night to watch Betelgeuse. I was mostly joking (but I did walk outside because I couldn't resist).
Andy Howell✔@d_a_howell
It isn't Betelgeuse blowing up because: - It is outside the GW localization region. - The burst might not even be real. - The burst was probably too short. - No neutrinos were detected - Betelgeuse's dimming is well explained. Me walking outside to check = buying a lottery ticket
As Andy said in one of the tweets above, gravitational wave detectors do sometimes detect false positives, about once every 25 years. So that is something to keep in mind.
The most important thing to keep in mind is that Betelgeuse has not exploded. Estimates suggest it won’t explode in our lifetimes … probably.
What’s so great here is the way that astronomers – some of Earth’s most curious people – have reacted, turning their attention and their telescopes toward Betelgeuse and toward the region of the sky from which the gravitational waves apparently originated. What is going on? The verdict isn’t in yet. Probably nothing. Still, many on Twitter last night spoke of going outside to look at Betelgeuse. Their enthusiasm and excitement are contagious!
Alex Martin@SidewalkSciGuy
Alright I *know* it's nothing, but LIGO just detected a gravitational wave burst from a region of sky near Betelgeuse.
*Tying shoes to go outside*: guys I know it's nothing.
*grabbing binoculars*: guys it's nothing
*throwing on a sweatshirt for an all-nighter*: it's nothing
Brian Ottum kindly provided this direct comparison of Betelgeuse a few years ago, and Betelgeuse in recent weeks. You can see that the star has dimmed noticeably. Brian wrote: “Left is February, 2016. Right is December 31, 2019. Note that the brightness/appearance of all background stars are identical left versus right, but Betelgeuse is definitely fainter on the right.” Thank you, Brian!
Bottom line: The LIGO and Virgo detectors this week recorded a “burst” of gravitational waves, from an area of sky near the red supergiant Betelgeuse, which has recently undergone a mysterious dimming. Hmmmmmm.
UFOs have been sighted by pilots and aircraft for decades, yet some of these truly stand out as something special. What has become known as being one of the earliest official UFO reports from a commercial airline crew began as a normal flight. On July 23, 1948, chief pilot Clarence Chiles and co-pilot John Whitted took off for a routine 7-hour flight from Houston, Texas to Atlanta, Georgia, aboard their Eastern Air Lines Douglas DC-3 passenger plane along with twenty passengers. The weather was clear and calm, and both pilots were very experienced, with distinguished flying careers during World War II, so there would have been no reason to think that this would be anything more than a typical, uneventful flight, but this would soon prove not to be the case at all, and it would propel itself into the realm of great UFO mysteries.
At approximately 2:45 AM on July 24, the plane was in the skies near Montgomery, Alabama, at an altitude of 5,000 feet when Chiles’ attention was drawn to what he would describe as “a dull red glow above and ahead of the aircraft,” and he mentioned it to Whitted, who also saw it. They at first took to be a military plane, but it would soon prove to be anything but, as it rapidly closed in on their position with astonishing speed in a horizontal path and silently whizzed by before shooting straight up into the sky while belching forth “a tremendous burst of flame out of its rear.” The proximity of the strange craft had been such that they had been forced to bank in an evasive maneuver, and Chiles would say of the encounter:
We veered to the left and it veered to its left, and passed us about 700 feet to our right and about 700 feet above us. Then, as if the pilot had seen us and wanted to avoid us, it pulled up with a tremendous burst of flame out of its rear and zoomed up into the clouds.
Both men would get a good look at it, describing it as having been a cigar-shaped metallic object 100 feet long and 25-30 feet in diameter, with no noticeable wings or tail section, and they would explain that they had seen two rows of brightly lit windows along its side. It would turn out that only one of the passengers, most of who had slept through it all, had seen anything usual, saying that he had seen an eerie red glow pass the plane. Other witnesses would later turn out to be personnel from Robbins Air Base, near Macon, Georgia, who would claim to have seen the same object shoot through the sky a half an hour before Chiles and Whitted’s encounter.
The plane made it to its destination on schedule, and the pilots wasted no time in reporting what they had seen to the US Air Force, who in turn called in investigators from Project Sign, which was an early Air Force group for studying UFO sightings and sort of a precursor to the more famous Project Blue Book. The pilots were extensively interviewed and they provided sketches of what they had observed, and it was found that their descriptions were remarkably similar except that Chiles claimed to have seen an actual cockpit on the craft, whereas Whitted had observed no such feature. Project Sign also meticulously mapped every known aircraft in the air for the entire southeastern United States in an effort to see if the object could have perhaps been another plane, but there was nothing else officially in the air at the time that could really explain the bizarre sighting. This, combined with the fact that the two pilot witnesses were seasoned professionals and had gotten a good, close look at the anomalous object, made this a very exciting, albeit alarming incident.
The idea that some large, unidentified flying object of this type had invaded U.S. airspace was a sensitive issue at the time, and so the Air Force was scrambling for answers. It was suggested that this could have possibly been some sort of advanced aircraft from a foreign nation, but this was problematic because the technology was seen as far beyond what anyone was capable at the time and nothing like it had been seen before. The detail of the flame shooting out of the rear of the craft was important in this regard, because in those days few aircraft had afterburners, and none of that magnitude. This was more like a rocket, but there was thought to be no conceivable way that such a massive low flying, horizontal rocket had been traveling through the area with the technology available at the time and with no discernible launching point.
Sketches of the craft
Other ideas were suggested at the time as well, such as that the pilots had simply misidentified a particularly brilliant meteor, but this does not explain the object’s ability to make a sudden vertical ascent, nor details like the double rows of windows. Project Sign also briefly entertained the idea that this could have been a brush with a Navy plane called the RV6 Constitution, which could have been on a classified mission and was top-of-the-line cutting edge stuff at the time, and also just happened to be cigar shaped, with the characteristic feature of two rows of windows, but it did not spew long jets of flame and certainly could not perform the radical vertical maneuver that was observed. The Navy, for its part, would also deny that this sort of plane had been anywhere near the area at the time.
By all accounts Project Sign was utterly meticulous and thorough with every aspect of the investigation, leaving no stone unturned and at every turn seeking to exhaust every possible option. In the end they had completely ruled out the meteor theory and had considered the notion that this had been some experimental aircraft highly improbable. In light of this, the Air Technical Intelligence Center (ATIC) compiled all of their findings into an “Estimate of the Situation” report, which allegedly came to the conclusion that the Chiles-Whitted object was an “interplanetary spaceship.” The top secret and highly classified report itself has become almost legendary, partly because it would have been the first time a government had ever conceded that UFOs were actually aliens, but also partly because it would shortly after disappear off the face of the earth and into history and the annals of great conspiracies.
The first head of The Air Force’s famous Project Blue Book study of UFO phenomena, Edward J. Ruppelt, would insist that the report did in fact exist, that it was sent all the way up through the chain of command, to land on the desk of General Hoyt S. Vandenberg, the chief of staff. The result? Well, Vandenberg apparently was skeptical of the estimate that the UFO was of alien origin, and doubted the evidence used to back that case up. Rather, he was a proponent of the idea held by another faction within the Air Force that believed that the object, and indeed UFOs in general, were the result of top secret aircraft being developed by the Soviet Union, which fit in perfectly with the Cold War paranoia at the time. According to Ruppelt, the report would then be totally dismissed and destroyed, saying:
The general wouldn’t buy interplanetary vehicles. A group from ATIC went to the Pentagon to bolster their position but had no luck, the Chief of Staff couldn’t be convinced. The estimate died a quick death. Some months later it was completely declassified and relegated to the incinerator.
The mysterious report has gone onto become the stuff of legend in UFOlogy, with occasional witnesses saying that they have seen a copy, but no concrete evidence that it ever even existed at all. There are no photographs of it, no known pages remaining from it, it is a specter lost to the mists of time, only reports of purported having seen the report up close. In the aftermath of this, the official Air Force verdict was and has remained that what Chiles and Whitted saw was a meteor. Case closed. Of course, in light of the other evidence of Project Sign’s findings on the case this explanation has been scoffed at and accused of being a weak attempt to obfuscate and blur the real truth, as has the fact that the actual report was apparently disposed of to leave us with nothing.
For their part, Chiles and Whitted would always stand by their account, never once faltering from what they believed was a truly anomalous situation and some sort of unknown craft. To this day the case is discussed heavily, and it remains a very credible one considering the pedigree of its pilots and the very thorough investigation that came to the conclusion that this might actually be something not of this earth. Yet not everyone obviously agrees, and so we are left with questions. If this wasn’t extraterrestrial in origin then what was it? A meteor, an experimental aircraft, what? Why would this remarkable and mysterious report make it all the way up through the upper echelons of the Air Force brass to merely be brushed aside and destroyed? Doesn’t incinerating it suggest they were merely trying to get rid of it? In the end we don’t know what it was, and it is all an intriguing mystery that we very well may never have the true answer to.
Astronomers discover class of strange objects near our galaxy’s enormous black hole
Astronomers discover class of strange objects near our galaxy’s enormous black hole

Astronomers from UCLA’s Galactic Center Orbits Initiative have discovered a new class of bizarre objects at the center of our galaxy, not far from the supermassive black hole called Sagittarius A*. They published their research in the Jan. 16 issue of the journal Nature.
“These objects look like gas and behave like stars,” said co-author Andrea Ghez, UCLA’s Lauren B. Leichtman and Arthur E. Levine Professor of Astrophysics and director of the UCLA Galactic Center Group.
The new objects look compact most of the time and stretch out when their orbits bring them closest to the black hole. Their orbits range from about 100 to 1,000 years, said lead author Anna Ciurlo, a UCLA postdoctoral researcher.
Ghez’s research group identified an unusual object at the center of our galaxy in 2005, which was later named G1. In 2012, astronomers in Germany made a puzzling discovery of a bizarre object named G2 in the center of the Milky Way that made a close approach to the supermassive black hole in 2014. Ghez and her research team believe that G2 is most likely two stars that had been orbiting the black hole in tandem and merged into an extremely large star, cloaked in unusually thick gas and dust.
“At the time of closest approach, G2 had a really strange signature,” Ghez said. “We had seen it before, but it didn’t look too peculiar until it got close to the black hole and became elongated, and much of its gas was torn apart. It went from being a pretty innocuous object when it was far from the black hole to one that was really stretched out and distorted at its closest approach and lost its outer shell, and now it’s getting more compact again.”
“One of the things that has gotten everyone excited about the G objects is that the stuff that gets pulled off of them by tidal forces as they sweep by the central black hole must inevitably fall into the black hole,” said co-author Mark Morris, UCLA professor of physics and astronomy. “When that happens, it might be able to produce an impressive fireworks show since the material eaten by the black hole will heat up and emit copious radiation before it disappears across the event horizon.”
But are G2 and G1 outliers, or are they part of a larger class of objects? In answer to that question, Ghez’s research group reports the existence of four more objects they are calling G3, G4, G5 and G6. The researchers have determined each of their orbits. While G1 and G2 have similar orbits, the four new objects have very different orbits.
Ghez believes all six objects were binary stars — a system of two stars orbiting each other — that merged because of the strong gravitational force of the supermassive black hole. The merging of two stars takes more than 1 million years to complete, Ghez said.
“Mergers of stars may be happening in the universe more often than we thought, and likely are quite common,” Ghez said. “Black holes may be driving binary stars to merge. It’s possible that many of the stars we’ve been watching and not understanding may be the end product of mergers that are calm now. We are learning how galaxies and black holes evolve. The way binary stars interact with each other and with the black hole is very different from how single stars interact with other single stars and with the black hole.”
Ciurlo noted that while the gas from G2’s outer shell got stretched dramatically, its dust inside the gas did not get stretched much. “Something must have kept it compact and enabled it to survive its encounter with the black hole,” Ciurlo said. “This is evidence for a stellar object inside G2.”
“The unique dataset that Professor Ghez’s group has gathered during more than 20 years is what allowed us to make this discovery,” Ciurlo said. “We now have a population of ‘G’ objects, so it is not a matter of explaining a ‘one-time event’ like G2.”
The researchers made observations from the W.M. Keck Observatory in Hawaii and used a powerful technology that Ghez helped pioneer, called adaptive optics, which corrects the distorting effects of the Earth’s atmosphere in real time. They conducted a new analysis of 13 years of their UCLA Galactic Center Orbits Initiative data.
In September 2019, Ghez’s team reported that the black hole is getting hungrier and it is unclear why. The stretching of G2 in 2014 appeared to pull off gas that may recently have been swallowed by the black hole, said co-author Tuan Do, a UCLA research scientist and deputy director of the Galactic Center Group. The mergers of stars could feed the black hole.
The team has already identified a few other candidates that may be part of this new class of objects, and are continuing to analyze them.
Ghez noted the center of the Milky Way galaxy is an extreme environment, unlike our less hectic corner of the universe.
“The Earth is in the suburbs compared to the center of the galaxy, which is some 26,000 light-years away,” Ghez said. “The center of our galaxy has a density of stars 1 billion times higher than our part of the galaxy. The gravitational pull is so much stronger. The magnetic fields are more extreme. The center of the galaxy is where extreme astrophysics occurs — the X-sports of astrophysics.”
Ghez said this research will help to teach us what is happening in the majority of galaxies.

Er gebeurt iets heel raars in het centrum van de Melkweg
Er gebeurt iets heel raars in het centrum van de Melkweg
Er gebeurt iets heel raars in het centrum van de Melkweg. Astronomen hebben zes objecten ontdekt rond Sagittarius A* die ze niet thuis kunnen brengen.
Ze gedragen zich zo vreemd dat ze zijn ingedeeld in een geheel nieuwe categorie: G-objecten.
De eerste twee objecten, G1 en G2, trokken bijna 20 jaar geleden voor het eerst de aandacht van astronomen.
Sterren
Het leek in eerste instantie te gaan om reusachtige gaswolken met een doorsnee van 100 astronomische eenheden.
Maar G1 en G2 gedroegen zich niet als gaswolken.
“Deze objecten zien eruit als gaswolken, maar gedragen zich als sterren,” zei astronoom Andrea Ghez van de Universiteit van Californië – Los Angeles.
Onduidelijk
Ghez en haar collega’s bestuderen het centrum van de Melkweg al meer dan 20 jaar.
Een team onder leiding van Anna Ciurlo heeft nu vier andere vreemde objecten ontdekt: G3, G4, G5 en G6.
Deze G-objecten draaien in 170 tot 1600 jaar om het zwarte gat.
Het is onduidelijk waar we hier mee te maken hebben.
Samensmelting
Ghez vermoedt dat de zes objecten oorspronkelijk dubbelsterren zijn geweest en onder invloed van de zwaartekracht van Sagittarius A* met elkaar zijn versmolten.
“Het samensmelten van sterren gebeurt mogelijk veel vaker in het universum dan we denken,” zei ze.
Het is mogelijk dat veel van de sterren die we volgen en niet begrijpen, het eindproduct zijn van een samensmelting, aldus Ghez.
At around 2:30 pm on 26th December 2003 in Huntington, Indiana, an off-duty police officer with the Huntington Police Department had just turned the key in the ignition of his car. He was warming up the engine against the cold afternoon winter environment of the American Midwest when he noticed something strange in the skies overhead.
The officer would later state how he at first believed the object to be a “parachute that you can steer. (It was) black and curved”. However, he soon noticed there was no pilot attached to it. Then, it began to roll, “a slow roll” before turning upside down and resembling a “giant set of bird wings”. Following more rolls, the object appeared much “oblong and orange”.
The officer would immediately reach for the police radio. He would request that any other available officers attempt to locate the mysterious object also. Within moments, two other Huntington police officers had confirmed the object overhead.
One of the officers to respond would later claim it looked like a “tire in the sky”. The third officer, who was leaving the police station when he heard the call for attempts to locate the mysterious object. He would claim that “it was so big” that he no problem at all locating it. He would further state that it would “glide, (and) rotate the wide way around” before hovering and turning a bright orange color.
All three of the officers would later state their belief that the orange color was more likely a reflection of the afternoon sun as opposed to a physical glow of the craft itself. Furthermore, all three would agree that the object made no noise whatsoever.
A Distinct (And Strange) Lack Of Public Reports!
By the time the object had come to rest and hovered at would ultimately be its lowest point, the first police officer believed it was “going to get hung up on the steeple of the church”.
What he would also remark was extremely strange was the fact that no calls came into the 911 switchboard from the public. The officer would remark that such an incident would have normally “lit up the emergency lines”. However, not one single report came into their station or any others, including the state police. At least, that is, as a caveat of our own, none that are available to the public.
It would appear that the three police officers, the first of which just happened to look up at the “right moment” would prove to be the only witnesses to such a public sighting, at low altitude in the middle of the day, no less. In fact, so strange was the apparent lack of response that all three of the witnesses would stop speaking of the sighting altogether due to feat that “people would think we were crazy”.
The first officer would lose sight of the strange craft after it made its way behind the church steeple. The two remaining officers would keep the object in their sights, each from slightly different locations (although, in reality, only separated by around 40 feet).
After around 30 to 45 seconds, the object disappeared from all of the officer’s view. Despite their initial promise to remain quiet, however, they would soon change their minds and make an official report of the incident several days later. A public account of the incident would appear in the Huntington Herald newspaper shortly after.
Witnesses And Details Of Reports Appear Credible!
It is certainly an interesting sighting. And one that all three of the officers have no doubt was of a machine that wasn’t “anything (they) could relate to”. Another of the officers would state that they were “never really afraid, just in total amazement”.
Whether the three officers were the only witnesses or whether there was a quick suppression of information is perhaps open to debate, although admittedly, unlikely in this instance.
Even the pastor of the church the object hovered over for several moments would claim, when asked for comment this was “the first (they) had heard of it” and that they hadn’t noticed anything unusual at all on the afternoon in question. Furthermore, much like the police department, he had received no reports from parishioners of any unusual aerial activity.
Initial investigations at the time of the reporting of the incident suggested not only credibility on the part of the witnesses, but also in the details they gave. Such things as the movement of the craft, the rolling and tumbling, as well as the bizarrely slow movement for such a large craft. Not to mention the complete lack of any sound whatsoever.
Two local airfields who might have managed to capture the object on their respective radars, Huntington Municipal Airport and Fort Wayne Smith’s Field, would both claim to have no reports or data to show any “out-of-the-ordinary” aerial vehicles for the afternoon of the 26th December.
What is also interesting, despite the three police officers being the only witnesses to this particular sighting, there were several other similar reports around Indiana during the Christmas and New Year period of 2003. NOTE: The above image is CGI.
‘PigeonBot’ brings flying robots closer to real birds
‘PigeonBot’ brings flying robots closer to real birds
Try as they might, even the most advanced roboticists on Earth struggle to recreate the effortless elegance and efficiency with which birds fly through the air. The “PigeonBot” from Stanford researchers takes a step towards changing that by investigating and demonstrating the unique qualities of feathered flight.
On a superficial level, PigeonBot looks a bit, shall we say, like a school project. But a lot of thought went into this rather haphazard looking contraption. Turns out the way birds fly is really not very well understood, as the relationship between the dynamic wing shape and positions of individual feathers are super complex.
Mechanical engineering professor David Lentink challenged some of his graduate students to “dissect the biomechanics of the avian wing morphing mechanism and embody these insights in a morphing biohybrid robot that features real flight feathers,” taking as their model the common pigeon — the resilience of which Lentink admires.
As he explains in an interview with the journal Science:
The first Ph.D.student, Amanda Stowers, analyzed the skeletal motion and determined we only needed to emulate the wrist and finger motion in our robot to actuate all 20 primary and 20 secondary flight feathers. The second student, Laura Matloff,uncovered how the feathers moved via a simple linear response to skeletal movement. The robotic insight here is that a bird wing is a gigantic underactuated system in which a bird doesn’t have to constantly actuate each feather individually. Instead, all the feathers follow wrist and finger motion automatically via the elastic ligament that connects the feathers to the skeleton. It’s an ingenious system that greatly simplifies feather position control.
In addition to finding that the individual control of feathers is more automatic than manual, the team found that tiny microstructures on the feathers form a sort of one-way Velcro-type material that keeps them forming a continuous surface rather than a bunch of disconnected ones. These and other findings were published in Science, while the robot itself, devised by “the third student,” Eric Chang, is described in Science Robotics.
Using 40 actual pigeon feathers and a super-light frame, Chang and the team made a simple flying machine that doesn’t derive lift from its feathers — it has a propeller on the front — but uses them to steer and maneuver using the same type of flexion and morphing as the birds themselves do when gliding.
Studying the biology of the wing itself, then observing and adjusting the PigeonBot systems, the team found that the bird (and bot) used its “wrist” when the wing was partly retracted, and “fingers” when extended, to control flight. But it’s done in a highly elegant fashion that minimizes the thought and the mechanisms required.
PigeonBot’s wing. You can see that the feathers are joined by elastic connections so moving one moves others.
It’s the kind of thing that could inform improved wing design for aircraft, which currently rely in many ways on principles established more than a century ago. Passenger jets, of course, don’t need to dive or roll on short notice, but drones and other small craft might find the ability extremely useful.
“The underactuated morphing wing principles presented here may inspire more economical and simpler morphing wing designs for aircraft and robots with more degrees of freedom than previously considered,” write the researchers in the Science Robotics paper.
Up next for the team is observation of more bird species to see if these techniques are shared with others. Lentink is working on a tail to match the wings, and separately on a new bio-inspired robot inspired by falcons, which could potentially have legs and claws as well. “I have many ideas,” he admitted.

Montauk Project Whistleblower Exposes Time Travel, Mind Control and Aliens
COAST TO COAST AM
Independent filmmaker Christopher Garetano, whose film about the Montauk mystery inspired the hit show “Stranger Things,” has spent a lifetime searching for the truth behind some of America’s most unusual stories.
In the first half, he joined Richard Syrett to continue their recent conversation (his phone connection was mysteriously lost on the 11/29 show), on the secretive Montauk Project.
A media phenomenon, Coast to Coast AM deals with UFOs, strange occurrences, life after death, and other unexplained (and often inexplicable) phenomena.
The Montauk Project is a conspiracy theory that alleges there were a series of secret United States government projects conducted at Camp Hero or Montauk Air Force Station in Montauk, New York, for the purpose of developing psychological warfare techniques and exotic research including time travel.

COAST TO COAST AM -
During some of the Apollo missions, modules were fired into the lunar surface, and the moon rang like a bell, in one case for around four hours. Because of this, Adair has concluded that the moon is hollow, and he also noted that its perfectly symmetrical shape is highly unusual compared to more lumpy satellites such as Deimos and Phobos that orbit around Mars.
The moon is simply too big to have been captured in Earth’s orbit, he remarked, so it would seem to have been flown in and placed here.

Proof That NASA Is A Spy Agency Using The Space Station To Do Its Dirty Work, UFO Sighting News.
Date of discovery: Jan 17, 2020 Location of discovery:Earths orbit from space station Source: NASA ISS Camera I was looking at some photos taken TODAY by the NASA camera on board the space station and noticed that it was really focusing on some places. For instance...this photo above looks a lot like a Chinese military base to me. Now a lot of people would say, Scott, perhaps they just took the photo by accident. One photo is an accident, but 30-40 photos is deliberate spying. The space station is suppose to be International...and yet they do not allow Chinese astronauts to participate on board the space station. They even gave the majority of control and ownership to Russia...which most people don't even know about. So...why is NASA participating in spying on foreign countries? I really don't think NASA would ever answer that one. This is 100% proof that NASA is a spy agency. Scott C. Waring
Now I checked the before and after photo and there was no UFO there. So that means its not something stuck to the lens, window or anything that moves slow. This object is moving really fast to be in only one photo. As you see, the space shuttle is turned with an open payload bay, but this isn't a satellite, because satellites don't move that fast. So...that leaves only one option...its an alien craft. This alien craft might not be a UFO but could however be one of the famous Black Knight satellites. Thats a satellite object, black non reflective and cannot be destroyed, but it will attack when provoked. Its said to be placed by Planet X, Nibiru so that they can constantly monitor Earth. Sadly, the Black Knight satellites also have the weaponry to destroy all life on earth instantly. Sterilizing the planet of life. Scott C. Waring
The US Navy has warned that the release of certain "TOP SECRET" UFO files requested under the Freedom of Information Act (FOIA) could “gravely damage” US national security.
According to Vice, in response to a recent Freedom of Information Act (FOIA) request, a spokesperson from the Navy's Office of Naval Intelligence (ONI) confirmed that the agency possesses several top-secret documents and at least one classified video pertaining to the 2004 UFO encounter.
The ONI spokesperson said that these documents were either labeled "SECRET" or "TOP SECRET" by the agencies that provided them, and that sharing the information with the public "would cause exceptionally grave damage to the National Security of the United States."
RT America’s Natasha Sweatte reports. Then former NASA astronaut Leroy Chiao joins Scottie Nell Hughes to weigh in on the case and the controversy surrounding UFOs and what they might be.
In November 2004, several U.S. Navy pilots stationed aboard the USS Nimitz encountered a Tic-Tac-shaped UFO darting and dashing over the Pacific Ocean in apparent defiance of the laws of physics. Navy officials dubbed the strange craft an "unidentified aerial phenomenon," but they have remained mum on what, exactly, that phenomenon could've been. Now, unsurprisingly to anyone who's ever considered making a hat out of tinfoil, the military has confirmed they know more than they're letting on.
In response to a recent Freedom of Information Act (FOIA) request, a spokesperson from the Navy's Office of Naval Intelligence (ONI) confirmed that the agency possesses several top-secret documents and at least one classified video pertaining to the 2004 UFO encounter, Vice reported.
According to the ONI spokesperson, these documents were either labeled "SECRET" or "TOP SECRET" by the agencies that provided them, and that sharing the information with the public "would cause exceptionally grave damage to the National Security of the United States."
These top-secret files included several "briefing slides" about the incident, provided to the ONI by an unnamed agency. (Because ONI officials did not classify the slides personally, they are unable to declassify them, the spokesperson added).
The ONI also admitted to possessing at least one video of unknown length, classified as "secret" by the Naval Air Systems Command (NAVAIR). ONI didn't reveal whether this footage is the same 1-minute video that was leaked online in 2007 and widely released by The New York Times in 2017. However, in November 2019, several naval officers who witnessed the incident aboard the Nimitz told Popular Mechanics that they had seen a much longer video of the encounter that was between 8 and 10 minutes long. These original recordings were promptly collected and erased by "unknown individuals" who arrived on the ship by helicopter shortly after the incident, one officer said.
Luis Elizondo, a former Pentagon staffer who helped make the Navy video public, told Vice that "people should not be surprised by the revelation that other videos exist and at greater length."
The FOIA request, submitted in October 2019 by an independent researcher, asked for access to any nonclassified records or portions of records regarding the 2004 UFO encounter. No additional documents were mentioned in the ONI's response besides the classified briefing and video.
The closest star to the sun might have a second planet in its orbit.
Proxima Centauri is our nearest neighboring star; it’s just 4.2 light-years away. It has one planet that astronomers know of, a potentially habitable world called Proxima b.
But in a new study, researchers from Italy’s National Institute for Astrophysics report that they have observed changes in the star’s activity that indicate it could have another planet. They dubbed the world Proxima c in their paper, which was published Wednesday in the journal Science Advances.
The potential new planet seems to be a super-Earth – the term for a planet with a mass larger than Earth but significantly smaller than the ice giant Neptune.
“Proxima Centauri is the nearest star to the sun, and this detection would make it the closest planetary system to us,” astronomer Mario Damasso, the paper’s lead author, told Business Insider in an email.
Proxima c (if it exists) is probably not habitable – given its distance from its star, the planet is probably freezing or shrouded in a suffocating hydrogen-helium atmosphere. But its proximity to us could offer a unique opportunity to study another star system.
Proxima c could be a super-Earth in an unexpected place

If it’s real, Proxima c should not exist where it is.
Astronomers think super-Earths form around the “snowline”: the closest distance to a star where water can become ice. That’s because icy solids accumulate in that region when a star system is in its infancy, helping to form planets.
Proxima c is far beyond that snowline, though, so its existence could challenge that theory.

Then again, researchers still aren’t sure whether planet exists at all.
The team discovered Proxima c using a technique called radial velocity. It works like this: Planets tug slightly on their stars as they orbit. When the star’s position moves, even in this small way, it changes the colors of its light. If those changes are cyclical, that suggests the cause is an orbiting planet.

Damasso’s team identified this type of cyclical change in Proxima Centauri’s light, and determined that it is unrelated to the movements of the planet Proxima b.
That suggested the presence of another planet, though Damasso said the researchers still “cannot discard the possibility that the signal is actually due to the activity of the star.”
So the team hopes to find more clues in data from the Gaia space telescope.
Help from Gaia and James Webb

The Gaia telescope launched in December 2013 with the ambitious goal of making a 3D map of the galaxy.
“Gaia is still observing, and we calculated in its final data release there will be enough data to confirm or disprove the existence of Proxima c,” Fabio Del Sordo, a co-author of the paper and an astrophysicist at the University of Crete in Greece, told Business Insider via email.
The next release of Gaia’s data is planned for this summer, followed by another in 2021. The timeline for the full data release has not yet been announced.
While Damasso and Del Sordo wait for that, they’re working with another team to scan photos of Proxima Centauri in search of signs of a second orbiting planet.
“Direct imaging may give results in a shorter time, but it cannot give a definitive answer,” Del Sordo said. “In other words, if we will not see anything in the image, it doesn’t necessarily mean Proxima c does not exist.”

The telescope is slated to launch in March 2021, equipped with a 21-foot-wide beryllium mirror and new infrared technology to make it sensitive to longer wavelengths of infrared light.
That could help astronomers study nearby stars and, specifically, Proxima c, in great detail.
“It will surely be a target for JWST, but since the planet is likely very cold, we do not know if JWST will be able to detect it,” Del Sordo said.
Even if James Webb can’t spot Proxima c, its neighboring planet, Proxima b, will be a prime target.
The star closest to the sun appears to host another world much colder than Earth
The star Proxima Centauri (illustrated) may host two planets — one confirmed, possibly habitable world (left), and another newly discovered potential planet (right) more massive than Earth.
The planet orbiting the star closest to the sun may have a neighbor.
Proxima Centauri, a dim red star just 4.2 light-years away, is already known to host one potentially habitable planet, Proxima b, that’s a bit more massive than Earth (SN: 8/24/16). Now, astronomers see hints of a second planet, this one much larger and farther from the star.
If it exists, Proxima c appears to be at least 5.8 times as massive as Earth and orbits its star about once every five Earth years, researchers report January 15 in Science Advances. Given its distance from Proxima Centauri, the planet is also much too cold to have liquid water, a key test for habitability.
Clues to the planet’s existence showed up in spectroscopic data of Proxima Centauri from two telescopes in Chile, Mario Damasso, an astrophysicist at the Astrophysical Observatory of Turin in Italy, and colleagues report. The data, which span 17 years, record the star’s back-and-forth motion relative to Earth. After accounting for the known planet, the researchers found hints of an additional unexplained wobble, likely caused by a second planet gravitationally tugging on the star.
Damasso’s team emphasizes that additional data are needed to confirm the planet’s existence. Given its proximity to Earth, Proxima c could be a prime candidate for direct imaging with next-generation supersized telescopes, the scientists say.
The Earth might be crawling with undiscovered alien creatures whose biochemistry is very different from life as we know it. An astrobiologist explains.
Life is pretty easy to recognize. It moves, it grows, it eats, it excretes, it reproduces. Simple. In biology, researchers often use the acronym MRSGREN to describe it. It stands for movement, respiration, sensitivity, growth, reproduction, excretion and nutrition.
But Helen Sharman, Britain’s first astronaut and a chemist at Imperial College London, recently said that alien lifeforms that are impossible to spot may be living among us. How could that be possible?
While life may be easy to recognize, it’s actually notoriously difficult to define and has had scientists and philosophers in debate for centuries – if not millennia. For example, a 3D printer can reproduce itself, but we wouldn’t call it alive. On the other hand, a mule is famously sterile, but we would never say it doesn’t live.
As nobody can agree, there are more than 100 definitions of what life is. An alternative (but imperfect) approach is describing life as a self-sustaining chemical system capable of Darwinian evolution, which works for many cases we want to describe.
The lack of definition is a huge problem when it comes to searching for life in space. Not being able to define life other than we’ll know it when we see it means we are truly limiting ourselves to geocentric, possibly even anthropocentric, ideas of what life looks like. When we think about aliens, we often picture a humanoid creature. But the intelligent life we are searching for doesn’t have to be humanoid.
Will they be like you and me, made up of carbon and nitrogen? Maybe not. It’s possible they’re here right now and we simply can’t see them.
Such life would exist in a shadow biosphere. By that, I don’t mean a ghost realm, but undiscovered creatures probably with a different biochemistry. This means we can’t study or even notice them because they are outside of our comprehension. Assuming it exists, such a shadow biosphere would probably be microscopic.
So why haven’t we found it? We have limited ways of studying the microscopic world as only a small percentage of microbes can be cultured in a lab. This may mean that there could indeed be many lifeforms we haven’t yet spotted. We do now have the ability to sequence the DNA of unculturable strains of microbes, but this can only detect life as we know it – that contain DNA.
If we find such a biosphere, however, it is unclear whether we should call it alien. That depends on whether we mean of extraterrestrial origin or simply unfamiliar.
Silicon-based life
A popular suggestion for an alternative biochemistry is one based on silicon rather than carbon. It makes sense, even from a geocentric point of view. Around 90% of the Earth is made up of silicon, iron, magnesium and oxygen, which means there’s lots to go around for building potential life.
Silicon is similar to carbon; it has four electrons available for creating bonds with other atoms. But silicon is heavier, with 14 protons (protons make up the atomic nucleus with neutrons) compared to the six in the carbon nucleus. While carbon can create strong double and triple bonds to form long chains useful for many functions, such as building cell walls, it is much harder for silicon. It struggles to create strong bonds, so long-chain molecules are much less stable.
What’s more, common silicon compounds, such as silicon dioxide (or silica), are generally solid at terrestrial temperatures and insoluble in water. Compare this to highly soluble carbon dioxide, for example, and we see that carbon is more flexible and provides many more molecular possibilities.
Life on Earth is fundamentally different from the bulk composition of the Earth. Another argument against a silicon-based shadow biosphere is that too much silicon is locked up in rocks. In fact, the chemical composition of life on Earth has an approximate correlation with the chemical composition of the sun, with 98% of atoms in biology consisting of hydrogen, oxygen and carbon. So if there were viable silicon lifeforms here, they may have evolved elsewhere.
That said, there are arguments in favor of silicon-based life on Earth. Nature is adaptable. A few years ago, scientists at Caltech managed to breed a bacterial protein that created bonds with silicon – essentially bringing silicon to life. So even though silicon is inflexible compared with carbon, it could perhaps find ways to assemble into living organisms, potentially including carbon.
And when it comes to other places in space, such as Saturn’s moon Titan or planets orbiting other stars, we certainly can’t rule out the possibility of silicon-based life.
To find it, we have to somehow think outside of the terrestrial biology box and figure out ways of recognizing lifeforms that are fundamentally different from the carbon-based form. There are plenty of experiments testing out these alternative biochemistries, such as the one from Caltech.
Regardless of the belief held by many that life exists elsewhere in the universe, we have no evidence for that. So it is important to consider all life as precious, no matter its size, quantity or location. The Earth supports the only known life in the universe. So no matter what form life elsewhere in the solar system or universe may take, we have to make sure we protect it from harmful contamination – whether it is terrestrial life or alien lifeforms.
So could aliens be among us? I don’t believe that we have been visited by a life form with the technology to travel across the vast distances of space. But we do have evidence for life-forming, carbon-based molecules having arrived on Earth on meteorites, so the evidence certainly doesn’t rule out the same possibility for more unfamiliar life forms.

Even ‘the most indestructible animals in the world’ cannot survive global warming, as experts find the Achilles' heel of Tardigrades is long-term exposure to high temperatures
Even ‘the most indestructible animals in the world’ cannot survive global warming, as experts find the Achilles' heel of Tardigrades is long-term exposure to high temperatures
Tardigrades can survive some of Earth's harshest environments
A new study found their weakness is long-term exposure to high temperatures
Tests showed they have a 50% chance of surviving temperatures above 98.78F
Experts now question how these creatures will survive global warming
Researchers have uncovered the Achilles’ heel Earth’s most indestructible animal – global warming.
Tardigrades can survive the vacuum of space, being frozen or exposure to radiation, but are unable to endure long-term exposure to high temperatures.
A study showed that specimens that were not acclimate to heat had a 50 percent mortality rate of surviving temperatures above 98.78 degrees Fahrenheit over a 24 hour period.
The specimens were collected in Denmark, which officials warn will suffer from warmer summers and longer heatwaves as a result of climate change, leaving experts to question the fate of these creatures in a warmer world.

Researchers have uncovered the Achilles’ heel Earth’s most indestructible animal – global warming. Tardigrades can survive the vacuum of space, being frozen or exposure to radiation, but are unable to endure long-term exposure to high temperatures.
‘Global warming is already having harmful effects on habitats worldwide and it is therefore important to gain an understanding of how rising temperatures may affect extant animals,’ the researchers from the University of Copenhagen in Denmark wrote in the study published in Scientific Report.
‘Here, we investigate the tolerance to high temperatures of Ramazzottius varieornatus, a tardigrade frequently found in transient freshwater habitats.’
‘Using logistic modelling on activity we evaluate the effect of 24 hour temperature exposures on active tardigrades, with or without a short acclimation period, compared to exposures of desiccated tardigrades.’
The team collected a sediment sample from a roof gutter in Denmark that contained adult tardigrades.
Postdoc Ricardo Neves, who i involved in the research, said: ‘The specimens used in this study were obtained from roof gutters of a house located in Nivå, Denmark.’
‘We evaluated the effect of exposures to high temperature in active and desiccated tardigrades, and we also investigated the effect of a brief acclimation period on active animals’
They found that about 50 percent of tardigrades in the active state died when the temperature was put up to 98.78 degrees Fahrenheit.
A study showed that specimens that were not acclimate to heat had a 50 percent mortality rate of surviving temperatures above 98.78 degrees Fahrenheit over a 24 hour period
If they were given time to acclimatize, they made it to 99.68 degrees.
However, the team observed specimens while in a cryptobiosis state, when they adapt to environmental stress, they could survive temperatures of up to 108.86 degrees for one hour.
And if exposed for 24 hours, the maximum temperature was 145.58 degrees Fahrenheit.
According to Climate Change Adaptation, a website run by Denmark's Ministry of the Environment and Food of Denmark and the Environmental Protection Agency, climate change will result in the country having warmer summers, longer heatwaves and more periods of drought.
‘The fact that the median lethal temperature for active R. varieornatus is so close to the median maximum temperature in Denmark—where the specimens used in this study have been sampled—is quite worrying in our opinion,’ Neves told Newsweek.
‘Before our study tardigrades were regarded as the only organism on Earth to survive a cataclysmic event, but now we know this is not true.’
‘[While tardigrades are] among the most resilient organisms inhabiting our planet, it is now clear that they are vulnerable to high temperatures. Therefore, it seems that even tardigrades will have a hard time handling rising temperatures due to global warming.’
WHAT ARE TARDIGRADES?
Tardigrades, also known as water bears, are said to be the most indestructible animals in the world.
These small, segmented creatures come in many forms - there are more than 900 species of them - and they're found everywhere in the world, from the highest mountains to the deepest oceans.
Tardigrades, also known as water bears, are said to be the most indestructible animals in the world.
They have eight legs (four pairs) and each leg has four to eight claws that resemble the claws of a bear.
Boil the 1mm creatures, freeze them, dry them, expose them to radiation and they're so resilient they'll still be alive 200 years later.
An illustration of a tardigrade (water bear) is pictured
Water bears can live through temperatures as low as -457 degrees, heat as high as 357 degrees, and 5,700 grays of radiation, when 10-20 grays would kill humans and most other animals.
Tardigrades have been around for 530 million years and outlived the dinosaurs.
The animals can also live for a decade without water and even survive in space.
Tardigrades are a lesson in survival skills. These tiny creatures can withstand extreme conditions — fromspace radiation to beingfrozen for decades.
Their hardiness inspires hope for post-apocalyptic life and the future of space travel. But new research suggests all is not well for the microscopic invertebrates here on Earth. Space radiation and freezing might not kill them, but our warming planet might be too hot to handle.
In a new study, researchers found that Ramazzottius varieornatus, a species of tardigrade found in transient freshwater habitats, are highly vulnerable to high temperatures over the long term. The water bears are so sensitive, in fact, that the negative effects of warming can be seen with just a slight temperature increase.
The results were published this week in the journal Scientific Reports.
Tardigrades are vulnerable to high temperatures over the long term, new research shows.
For the study, researchers gathered tardigrade specimens from gutters on the roof of a house in Nivå, Denmark. They then exposed both active and desiccated (dehydrated) tardigrades to high temperatures for 24 hours. They did the same with tardigrades that had been allowed to become accustomed to higher temperatures, too.
Among non-acclimated active tardigrades, a temperature of 37.1 degrees Celsius tended to prove lethal. For acclimated tardigrades, the fatal temperature was slightly higher, at 37.6 degrees Celsius. Denmark’s current maximum temperature is just 36.4 degrees Celsius — that’s not much of a difference to the lethal temperature, suggesting tardigrades may be especially vulnerable to a warming Earth.
Surprisingly, the desiccated specimens were more resilient than their active study mates. Among the dried-out tardigrades, exposure to the burning heat of 82.7 degrees Celsius for an hour led to a 50 percent mortality rate. But over the course of 24 hours, a lower temperature — 63.1 degrees Celsius — was enough to trigger the same number of deaths, the study finds.
There’s evidence that some tardigrade species can tolerate temperatures as high as 151 degrees Celsius, according to the study. But those exposures lasted just 30 minutes — perhaps not long enough for the deadly effects of heat to take hold.
The study spotlights a harsh truth: When it comes to surviving and thriving in a changing climate, every creature — no matter how hardy — has its limits. Hopefully studies like this can encourage us not to test those boundaries.
Abstract:
Global warming is already having harmful effects on habitats worldwide and it is therefore important to gain an understanding of how rising temperatures may affect extant animals. Here, we investigate the tolerance to high temperatures of Ramazzottius varieornatus, a tardigrade frequently found in transient freshwater habitats. Using logistic modelling on activity we evaluate the effect of 24 hour temperature exposures on active tardigrades, with or without a short acclimation period, compared to exposures of desiccated tardigrades. We estimate that the 50% mortality temperature for non-acclimated active tardigrades is 37.1 °C, with a small but significant increase to 37.6 °C following acclimation. Desiccated specimens tolerate much higher temperatures, with an estimated 50% mortality temperature of 82.7 °C following 1 hour exposures, but with a significant decrease to 63.1 °C following 24 hour exposures. Our results show that metabolically active tardigrades are vulnerable to high temperatures, yet acclimatization could provide a tolerance increase. Desiccated specimens show a much higher resilience—exposure-time is, however, a limiting factor giving tardigrades a restricted window of high temperature tolerance. Tardigrades are renowned for their ability to tolerate extreme conditions, but their endurance towards high temperatures clearly has an upper limit—high temperatures thus seem to be their Achilles heel.
One of the classics of Fortean phenomena is things falling mysteriously from the sky. Whether it’s bright balls of fire, creatures living or dead, rocks or inappropriately colored precipitation, they’re the kind of events that occupied a sizable chuck of The Book of the Damned, the compendium of all things strange complied by Charles Fort. Most places are fortunate enough to only be listed once as victims of Fortean events. If the author were still compiling stories today, the latest edition would have the Russian city of Chelyabinsk in it twice – once for the famous meteor that blasted over the city on February 15, 2013, (and whose chunk allegedly has mystical lifting powers) and the other for the mysterious green snow which fell this week and has some who remember the falling superbolide wondering if they’re related. Are they?
“Precipitation with a pronounced green tint fell on the section of the Ural road near the entrance to Chelyabinsk, between the gardens and the village of Slavino. Atypical type of snow lies directly along the highway, in fact, 400 meters from the border of the city, and a kilometer from the Kashtak Bor.”
The Kurs Dela Russian media site posted a video of the green snow (see it here) on January 12 and it was immediately picked up by other sites and Twitter feeds. As usual, the tweets are more interesting.
“Green snow in the Chelyabinsk region appeared to cheer up Chelyabinsk residents who showed signs of depression due to a long winter.”
“Why not cosmic dust? Or seaweed? Or is it just an optical illusion? Someone sees green snow, and someone – snow is the color of money sawn on the “installation” of filters. (Google translation)”
Is it green meteor dust?
And some see a logical and typically Russian explanation.
“The regional Ministry of Ecology explained the green snow in Chelyabinsk. A strange color rainfall at the entrance to the city from the side of Yekaterinburg was recently discovered by citizens. On Monday, January 13, department specialists left the site and came to the conclusion that the snow turned green due to dust from a nearby granite quarry.”
And, like any good Russian government agency, the Ministry of Ecology points out that the green snow is not just safe, it’s all-natural.
“This dust does not pose a threat to public health. These are particles of natural materials and rocks.”
Perhaps Chelyabinsk would get an honorable mention, or at least an asterisk, in an updated Book of the Damned. In 2017, the snow in the city also turned green. That time, the cause was also somewhat ‘natural’ – a green food coloring that leaked from a collector at a paper mill which uses it to make … remember, this is Siberia … green toilet paper.
The Great 2020 Green Snowfall of Chelyabinsk appears to be due to dust caused by blasting at the local granite quarry. Green dust from granite? It’s no wonder the locals who have lived through the mysterious dome-lifting meteor and a previous green snow are skeptical.
Fortunately, they can console themselves with a fresh roll of green toilet paper.
Today’s article is the final installment of my 3-part feature concerning why I believe that many cryptozoological creatures – such as Bigfoot, lake monsters, the Dogman, and the Alien Big Cats of the U.K. – are actually supernatural in nature and should not be a part of Cryptozoology. Today, I’m focusing on the Chupacabra of Puerto Rico. It was in the mid-1990s that the phenomenon of the chupacabra exploded all across Puerto Rico. So far as can be determined, the menacing creature first surfaced in March 1995. That was when numerous animals were found slaughtered in the towns of Morovis (located in central Puerto Rico) and Orocovis, which is situated within the aforementioned La Cordillera Central mountain range. Locals were plunged into states of near-hysteria by the attacks, which reportedly left animals dead, with strange marks on their necks, and a distinct lack of blood in their corpses. Since many of the early attacks were on goats, the term, “chupacabra,” was created. It means, in Spanish, goat-sucker.
Vampires were on the loose; monstrous vampires. Reports of strange killings soon began to surface from other parts of the island. The creatures were clearly on the move. The death-rate increased even more. The population was on edge and the media had something new and sensational to report on. It was a turbulent and strange time. But, what, exactly, was responsible for all the killings? Yes, there were plenty of dead animals but, unfortunately, there was no solid, eyewitness testimony relative to the killers themselves. That is, until August 1995, when a woman named Madelyne Tolentino – who lived in Canovanas, which is close to the northeast coast of Puerto Rico – changed everything. Tolentino’s description of the creature she encountered, close to her mother’s home, was disturbing, to say the very least. It was a description eagerly embraced by the island’s media and by investigators of monsters and mysteries.
Artist’s depiction of a chupacabra (wikipedia)
Tolentino told journalists and researchers that the creature was around three feet in height, bipedal, ran in a weird, hopping fashion, had large black eyes, bony fingers on each hand, overly long arms and legs, and a kind of feathery line running down its back. Or, it appeared to Tolentino to be a feathery line: a young boy employed by Tolentino’s husband claimed that he saw the beast up close and personal and maintained that the feathers were, in reality, sharp spines. The boy also said that the creature possessed a mouthful of vicious-looking fangs. Not only did the people know of the chupacabra and its predations, they also now knew what it looked like: something straight out of their worst nightmares. As the years progressed, so did the attacks. And so did the weird cases, that suggest the chupacabra are supernatural beasts.
Here are a couple of examples from my many trips to Puerto Rico. There is a longstanding story of a UFO crashing in the heart of Puerto Rico’s El Yunque rain-forest in February 1984. I know that, because the basics of the account have reached me on three occasions over the past decade. It was early one morning when a large, circular-shaped object slammed into the ground, immediately after flying over the rain forest in a decidedly erratic fashion. To prevent people from learning the truth of the matter, a diversionary tactic was put into place that the UFO was a meteorite. Personnel from NASA, the U.S. Air Force, and the CIA were soon on the scene – in part, to scoop up the pummeled body-p arts of a couple of dead chupacabras, whose lives came to sudden and bloody ends when the alien craft hurtled violently into the forest at high speed. That’s how the story goes, anyway.
There is another reason why I am so intrigued by the potential UFO link to the chupacabra controversy. It’s because of something that happened back in 2004. Shortly after my Proof Positive shoot was completed for the SyFy Channel, I spoke with a woman who had her own encounter with a UFO, but in a location where a chupacabra was seen only days later. As Rosario told me, it was early March 2000, and she was working in a grove near the foot of El Yunque where she picked plantains. Her attention was suddenly drawn to a deep, resonating hum, one that was coming from directly above her. Looking up, Rosario was startled to see a black, triangular-shaped object – about 25 to 35 feet in length – that was hovering overhead at a height estimated to be around 90 to 120 feet, and which had a glossy, shiny surface. Surprise and amazement turned to shock when a pencil-thin beam of light shot out of the base of the craft, fanned out, and enveloped Rosario in a pink glow.
For what almost seemed like an eternity, Rosario was rooted to the spot, while her mind was flooded with images of widespread nuclear destruction and environmental collapse in the Earth’s near-future. The final image was of a large, bald head with huge, black eyes and that closely resembled the alien face on the cover of Whitley Strieber’s 1987 best-selling book, Communion – which Rosario was inexplicably drawn to read in the immediate aftermath. Suddenly, the light retracted and the flying triangle rose into the sky, heading slowly towards the heart of the rain forest. Interestingly, in the wake of the encounter, Rosario developed an overwhelming interest in environmental issues, and quite literally overnight – after a lifetime of eating meat – became a staunch advocate of vegetarianism.
That was not all: three days later, and only a couple of hundred feet from where Rosario was working on that fateful day, two girls spotted a chupacabra of the bipedal, spiked and decidedly menacing kind. The beast spotted them, too. Evidently, however, it was a monster on a mission, since, after peering at them for a few moments it fell down on all-fours and bounded away into the heavy undergrowth. It was an event that – due to both the time-frame and the proximity – led Rosario to conclude the chupacabra was somehow linked to the UFO phenomenon. Me, too.
