FOIA Documents Reveal AARO’s Authorized and Repeated Attempts to Engage with David Grusch
FOIA Documents Reveal AARO’s Authorized and Repeated Attempts to Engage with David Grusch
The All-domain Anomaly Resolution Office (AARO), tasked to investigate Unidentified Anomalous Phenomena (UAP), made numerous attempts to interview UFO whistleblower David Grusch regarding his claims of U.S. Government engagement with extraterrestrial materials and technologies. These new documents were just released to The Black Vault in FOIA case 24-F-0266, which was filed on November 2, 2023, and they outline not only the timeline of events to contact Grusch, but numerous text messages and emails.
The following is an overview and brief timeline, as explained in a January 8, 2024, Memorandum for Record, which was one of the documents released in the case.
Timeline of AARO’s Attempts to Engage David Grusch:
June 8-13, 2023: Initial contact was made with known associates of Grusch, urging them to have him speak with AARO. These efforts were clarified during dialogues between AARO’s Director and individuals close to Grusch.
June 26, 2023: AARO staff reached out directly for Grusch’s contact details and extended an interview invitation, which Grusch declined.
June 28, 2023: After Grusch’s congressional testimony, AARO sought any verifiable information he might have shared with Congress.
July 27, 2023: Further attempts to arrange an interview through another associate of Grusch, who was meeting him the following day.
October 6, 2023: A secure call was made to encourage Grusch to participate in a formal interview.
November 10, 2023: Grusch agreed to be interviewed on November 14, after Congressional staff urged his cooperation.
November 14, 2023: Grusch failed to appear at the scheduled interview, expressing doubts about AARO’s authorization to handle classified information.
November 19, 2023: AARO contacted Grusch again, reiterating their authorization and inviting him to discuss his claims, which he declined.
January 8, 2024: AARO provided additional documentation to address Grusch’s concerns about confidentiality and classification handling, maintaining a standing invitation for an interview.
As noted in the above email also released in the records, there was a scheduled meeting with Grusch after he finally agreed to meet. However, he never showed, and seemingly even left them waiting in the lobby at the agreed meeting time and location.
Grusch later apologized in an email, but alluded to his no-show being tied to what he felt were unanswered questions that he wanted addressed prior to the meeting.
After the timeline was outlined, the memorandum ended with, “During interactions between AARO and Mr. Grusch from November 2023 to January 2024, it became evident that Mr. Grusch had no intention of providing AARO with information regarding his claims.”
But the memorandum outlining the timeline of contact attempts was not the full extent of the release. Numerous emails and text message exchanges were provided to support the above timeline.
One example of the latter were text message exchanges between Christopher Mellon, a former Deputy Assistant Secretary of Defense for Intelligence, and Dr. Sean Kirkpatrick, the Director of AARO at the time they were written, on the encrypted text messaging system known as Signal. These messages reveal Mellon attempting to mediate between Grusch and AARO to clarify misunderstandings about AARO’s legal capacities.
Note: Mellon’s texts are in the grey/white and Kirkpatrick is in blue/white.
Through Mellon, Grusch was asking why AARO just did not get their information from the Inspector General’s office, as Kirkpatrick then explained due to the “criminal investigation” aspect of the material, they would not have access to it until the IG decided to release it. However, Kirkpatrick explained that Grusch still was able to give his testimony and evidence to AARO directly, outside of the criminal investigation.
Kirkpatrick labels Grusch’s assertions and Mellon’s response to him as “absurd and false” during the exchange.
Another exchange showed how Kirkpatrick told Mellon he was “… defending and adjudicating, and [Mellon was] undermining the very organization [he]purported to help establish for this purpose.” Mellon’s response was that he never claimed Grusch’s claims were “accurate” but he felt Grusch was “sincere and credible.” His full response is above. (Note: The message appears to have been cut off. An appeal has been filed for the rest of it under the “Read More” link, as shown in the screen shot).
The exchanges released began on June 11, 2023, and lasted until June 13, 2023. Another exchange was at an unknown date relaying AARO’s position that, “By law, AARO may receive all UAP-related information, including any classified national security information involving military, intelligence, and intelligence-related activities, at all levels of classification regardless of any restrictive access controls, special access programs, or compartmented access programs.”
Mellon agreed to pass that on to Grusch’s attorney, then he stated he would, “… seek to avoid further communication unless it is something that seems extraordinary or if [likely Kirkpatrick]initiate.” No further communication between Mellon and Kirkpatrick was released.
March 8. 2023, memorandum by Major General David W. Abba
Another document in the FOIA release is the memorandum confirming AARO’s authority to receive and handle all UAP-related information, regardless of its classification. This memorandum, signed by Major General David Abba, Director, DoD Special Access Program Central Office (DoD SAPCO), explicitly states that AARO representatives are authorized to engage with individuals who possess sensitive U.S. Government information about UAPs, even if bound by nondisclosure agreements. This document is crucial because it directly counters Grusch’s claims of legal and security risks in cooperating with AARO, providing a clear legal basis for AARO’s ability to hear details about his story.
It should also be noted, that on April 17, 2024, Abba took part with the now acting Director of AARO Tim Phillips, in a classified briefing for some members of Congress. Details of that briefing, as of the writing of this article, are scant.
The detailed FOIA documents, including the timeline of engagements and the text messages with Christopher Mellon, demonstrate AARO’s persistent and legally supported efforts to involve David Grusch in their investigation. Despite these efforts, Grusch’s refusal to cooperate, based on disputed claims about AARO’s authority, raises more questions about the discrepancies between his public statements and his actions. The memorandum affirming AARO’s authorization to receive classified information is a critical piece of evidence supporting the office’s capacity to conduct its mandated tasks, reinforcing AARO’s role in the ongoing UAP investigations.
Numerous attempts by The Black Vault in the past to contact David Grusch about his claims have never been returned. No attempt was made to contact him for this specific article as all methods to contact him have been exhausted. The results of the appeal on the above case will be posted, when available.
In our twenty-fourth episode of Unsolved Canadian Mysteries, Kenton de Jong and Dylan Fairman discuss Edwin Fuhr’s close encounter of the second kind, which occurred on Septemeber 1st, 1974.
Edwin Fuhr was a farmer near Langenburg, Saskatchewan and was out one morning harvesting his canola, when he rode his swather up a small hill on his property. From this vantage point, he saw five strange metallic objects in a semi-circle-like shape, all hovering silently near a slough. He approached the objects on foot, noticing their dimensions, the speed in which they were rotating, and any feelings of uneasiness he felt near them,
He then returned to his swather and waited until eventually the objects flew up and away from him, blasting him with steam.
He would return home to tell his family what he saw, only to discover time had passed. After lunch, we went out to the spot with his father to show him where the objects were hovering. It was around this time that Edwin’s wife told his sister, and his sister told her husband and her husband called the RCMP.
It was after this moment that Edwin’s life changed, a mass of humanity descended upon his farm.
What did Edwin see that day in 1974? Was it alien in origin? Was it a secret military aircraft? And did he really get a call from Neil Armstrong? Listen to the podcast and find out!
David Michael Jacobs was an Associate Professor of History at Temple University for nearly four decades before his retirement a few years back. Tenured in 1981, he taught a variety of classes with a focus on 20th-Century American history, including one that's made him infamous: Unidentified Flying Objects in American Society. The three-credit course was perpetually popular. Students were invited to learn about "American society's reaction to the UFO phenomenon". Jacobs analyzed "UFOs and the controversy that has surrounded them by studying the attitudes of various groups toward the phenomenon". At the culmination of the course, Jacobs shared his own personal research, comprised ofthousands of hypnosis-based interviews with 150 people who claimed to have been abducted by aliens. He also told students his personal beliefs: that aliens are here, they are abducting humans, and may be intent upon planetary domination.
A few more of his conclusions, not necessarily shared with students, but openly available on his personal website: Humans are being impregnated and forced to have hybrid babies. These hybrids are now walking amongst us. At least two percent of Americans have been abducted. Aliens use a "mindscan" procedure to effectively entrance humans.
If not for his ivory tower position, Jacobs could easily be dismissed as a crank. His genial, humble demeanor also cloaks his pseudoscientific stance.
"I have tried to be as objective and as 'agenda free' as possible," he says. "I have no New Age, spiritual, religious, transformational, or transcendent program to promote. I try to stay as close to the evidence as I can. However, there is no possibility that I have avoided error. The majority of evidence for the alien abduction phenomenon is from human memory derived from hypnosis administered by amateurs. It is difficult to imagine a weaker form of evidence. But it is evidence and we have a great deal of it. Still, readers must be skeptical of what I say and of what all others say in this tangled arena of alien abductions, hypnosis, popular culture, and memory."
Jacobs' self-deprecation doesn't shield him from being wrong, however. His evidence – interviews with alleged abductees using amateur hypnosis – is not really evidence at all. Rather than the stories being real, it's far more likely that Jacobs is accidentally prompting his subjects to unwittingly fabricate them. Alternatively, in subjects' relaxed state, they may just be regurgitating information that was widely available. Or they may be misinterpreting nightmares or sleep paralysis as alien visitation. Jacobs admits that alleged abductees have a key commonality: either their mother, father or both were abductees as well. This suggests a compromised mental state may factor in to their frightening tales.
Jacobs' claims also have no convincing physical evidence, which he persistently attempts to explain away.
If you argue that there's no actual evidence of abductions, no smartphone movies, for example, he says the aliens are invisible.
"They take people through walls, windows, and ceilings. During this part of the abduction scenario, the UFOs, the aliens, and the abductees have been rendered 'unseeable.' This is advanced technology at work."
If you contend that there's no way intelligent aliens could reach Earth due to the vastness of space and the inconceivability of traveling faster than light, he counters that aliens have technology that we can't fathom.
"At this point we cannot know the levels of science and technology that ultimately led to the development of a method of transportation to Earth that surmounted what we presently see as insuperable difficulties."
If you ask why scientists haven't noticed any human-alien hybrids by now, Jacobs simply says you can't tell them apart from real humans.
"A fire-breathing dragon lives in my garage," Sagan claims...
"Show me," you say. I lead you to my garage.
You look inside and see a ladder, empty paint cans, an old tricycle — but no dragon. "Where's the dragon?" you ask.
"Oh, she's right here," I reply, waving vaguely. "I neglected to mention that she's an invisible dragon."
You propose spreading flour on the floor of the garage to capture the dragon's footprints.
"Good idea," I say, "but this dragon floats in the air."
Then you'll use an infrared sensor to detect the invisible fire.
"Good idea, but the invisible fire is also heatless."
You'll spray-paint the dragon and make her visible.
"Good idea, but she's an incorporeal dragon and the paint won't stick."
And so on. I counter every physical test you propose with a special explanation of why it won't work.
"Now, what's the difference between an invisible, incorporeal, floating dragon who spits heatless fire and no dragon at all?" Sagan asks, before explaining. "Claims that cannot be tested, assertions immune to disproof are veridically worthless, whatever value they may have in inspiring us or in exciting our sense of wonder."
Just like Jacobs' human-abducting, malevolent aliens...

Woman, 29, has 'daily' encounters with aliens after first UFO visit during lockdown
Lily Nova, 29, from St Louis, Missouri, US, says she had her first encounter with aliens in November 2020 after taking up astrophotography to cure her lockdown boredom
A woman who claims to have spotted a UFO during lockdown says she's been visited by aliensever since.
Lily Nova, 29, from St Louis, Missouri, US, says she had her first encounter at the end of 2020 after taking up astrophotography to cure lockdown boredom.
But the encounters did not stop there, with Lily now claiming the extraterrestrial beings visit her on a daily basis.
They've approached her in all manner of spacecraft, including metallic ships, black triangles and orbs that move in an "unearthly" way, she claims.
She also says she knows what some of the beings look like.
She claims the alien beings showed themselves to her through "telepathy"
( Image: Caters News Agency)
She first started getting into astrophotography in the summer of 2020 during the lockdown which eventually led to her first encounter with aliens just a few months later, in November.
She said: "My first encounter with aliens and UFOs was very intense.
"I went outside for some fresh air one night and I immediately locked eyes with bright light hovering over the neighbourhood.
"I started investigating and realised it was a UFO. Seconds later I looked away briefly and when I looked back there was a second craft that was much closer.
"I could actually see the triangular shape of the craft.
"The UFOs did some impressive manoeuvres to show me that it wasn't a regular aircraft before they disappeared above me.
"It really spooked me because aliens and UFOs aren't something I have thought about much before. It was a total reality shifting experience.
Astrophotography is a hobby where people take pictures of the deep sky - celestial objects in our solar system
( Image: Caters News Agency)
She says they've chosen to visit her because she is "open minded" and "welcoming" towards them

"A couple of months later I had my second encounter. After that, it kept happening more frequently and now I am having experiences daily.
"During my encounters I have also been able to see what the beings look like.
"One of the first beings I saw was a girl with light blue skin. She had no hair, but she was very beautiful. She was wearing a skin tight grey suit and I saw her ship mates standing behind her in the same uniform.
"I have also seen another group of beings with light blonde hair, fair and glowing skin and bright blue eyes.
"I believe they send images of themselves to me through telepathy. I think they are easing me into an introduction as it would be such a shocking experience for any human to have an alien walk up to you."
Lily believes that the aliens were testing the waters with her after her first shocking encounter as she says they were motioning towards her and knew she was recording.
She thinks that they then gave her some space to process the experience before appearing to her again.
She claims to have seen black orbs and other UFOs moving in an "unearthly manner"

Lily added: "My encounters have been very close from the start. I could not believe what I was seeing, it was groundbreaking and it piqued my interest in astrophotography even more.
"I needed to find out as much as possible.
"I abandoned my career as a nutritionist because it was overtaken by my passion for finding out more about UFOs and aliens.
"It's not something I ever expected to happen.
"The shock of my encounters with the UFOs eventually turned to comfort as I had more and more experiences. "It felt like I was developing a relationship with them.
"These experiences have changed everything for me. It has totally changed my view of the world and I have learnt so much about the cosmos and other beings.
"I have been focusing on spreading awareness of what I have found."
Lily now believes that she can invite these experiences with aliens and UFOs when is she is in a relaxed, open and blissful state of mind.
She says that she has even developed a sixth sense and intuitive gut feeling for when they are going to appear to her.
Lily added: "Whenever I am out doing my creative passion, astrophotography, this is when I believe I can make contact and invite these encounters.
"During my first initiated contact, where I have invited them instead of them just showing up, I even received a vision of being on the space ship and of the ships crew members.
"I have been out with a friend who is experienced in meditation, and we set our intention for them to appear to us, and within five minutes of getting out the car, a bright golden orb appears and was moving around to our questions
"Since the shock wore off, I just feel joy, love and peace. They are such beautiful and positive experiences, sometimes I even ball my eyes out crying while it's happening.
"I believe that they come to me because I believe in them, I am open-minded and I am welcoming towards them.
"It has been fascinating to learn about the universe and to create the incredible connection that has been formed."
A woman from St. Louis, Missouri named Lily Nova claims to have daily encounters with aliens and even gave up her career to pursue more knowledge about them.
Nova claims that her first alien encounter occurred during the pandemic after she took up astrophotography to combat her boredom.
“My first encounter with aliens and UFOs was very intense,” the Mirror reports she claimed. “I went outside for some fresh air one night and I immediately locked eyes with bright light hovering over the neighborhood. I started investigating and realized it was a UFO.
“Seconds later I looked away briefly and when I looked back there was a second craft that was much closer. I could actually see the triangular shape of the craft. The UFOs did some impressive maneuvers to show me that it wasn’t a regular aircraft before they disappeared above me.”
Lily Nova claims that she has seen numerous aliens over the span of her many encounters with UFOs.
She says she once saw an alien girl with light blue skin with no hair who “was very beautiful” and “wearing a skin-tight grey suit.”
“I have also seen another group of beings with light blonde hair, fair and glowing skin and bright blue eyes,” Nova added. “I believe they send images of themselves to me through telepathy. I think they are easing me into an introduction as it would be such a shocking experience for any human to have an alien walk up to you.”
Nova says that after her alien encounters she gave up her career as a nutritionist “because it was overtaken by my passion for finding out more about UFOs and aliens.”
She also claims that she has developed a sort of sixth sense when it comes to knowing when the encounters will occur.
“Whenever I am out doing my creative passion, astrophotography, this is when I believe I can make contact and invite these encounters,” she said. “I have been out with a friend who is experienced in meditation, and we set our intention for them to appear to us, and within five minutes of getting out the car, a bright golden orb appears and was moving around to our questions.”
Lily Nova and Demi Lovato should get together sometime and exchange notes.
Als we het hebben over invasieve uitheemse soorten, bedoelen we dieren die zijn geïntroduceerd in een ecosysteem waar ze geen deel van uitmaken, maar die daardoor een bedreiging vormen voor de lokale biodiversiteit. Er zijn veel voorbeelden, zoals de blauwe krab en de Louisiana rivierkreeft, of zoogdieren die door kolonisten naar verschillende delen van de wereld zijn gebracht. Heel anders is het geval van de gigantische hagedissen die onlangs in Florida zijn gespot, reptielen die vreemd zijn aan het lokale ecosysteem maar een potentieel gevaar vormen voor dieren en mensen. Laten we eens kijken wat het zijn en waarom ze in Florida voorkomen.
Gigantische hagedissen in Florida: een steeds vaker voorkomende waarneming
Over waarnemingen van reuzenhagedissen in Florida wordt met min of meer regelmatige tussenpozen gesproken, maar de laatste jaren steeds vaker. Een van de meest recente incidenten werd gedocumenteerd door een vrouw genaamd Renee Aland, die video's en foto's deelde van een waarneming op een paar meter afstand.
Op de beelden is een groot reptiel van bijna twee meter lang te zien dat bekend lijkt te zijn met de verharde wegen van Florida. Renee vertelt hoe het in een kanaal dook en kort daarna weer boven water kwam, zonder acht te slaan op de vrouw die filmde met haar mobiele telefoon en ondertussen haar dochter aanspoorde om niet uit de auto te stappen. Nadat ze de video en de beelden had gedeeld op sociale media, stuurde de vrouw de documentatie ook naar de Florida Fish and Wildlife Conservation Commission, die de waarneming zal afhandelen en het dier mogelijk zal vangen. Maar wat was het precies?
Wat zijn de gigantische hagedissen die in Florida werden gespot?
Volgens functionarissen van het FFWCC, en afgaande op Renee's beelden, zijn de reuzenhagedissen die in Florida zijn gezien Aziatische watervaranen, wetenschappelijke naam Varanus salvator. Het gaat om een reuzenhagedis die zelfs langer kan worden dan twee meter en iets kleiner is dan de Komodovaraan, een van zijn naaste verwanten. Aziatische watervaranen worden dan ook vaak verward met Komodovaranen, waar ze fysiek op lijken.
Net als Komodovaranen kunnen watervaranen zich voeden met grotere prooien en bezitten ze gifklieren in hun onderkaak. In de praktijk bijten ze hun prooi en kunnen hem dan zelfs uren of dagen volgen, wachtend tot het gif effect heeft. Deze reuzenhagedissen komen oorspronkelijk uit Zuidoost-Azië, maar waarom bevinden ze zich dan in Florida?
Waarom zijn er varanen in Florida?
Dat er Komodovaranen of watervaranen in Florida zijn is niet verrassend, omdat ze misschien te gast zijn in een dierentuin en dus geen invasieve uitheemse soorten zijn. Het probleem is een ander: watervaranen worden vaak geïntroduceerd als exotische huisdieren, en slagen er misschien in om uit gevangenschap te ontsnappen of worden vrijgelaten door hun eigenaars. Daardoor worden het uitheemse en invasieve dieren die de biodiversiteit van het gebied in gevaar kunnen brengen.
Dit is een wijdverspreid maar weinig besproken probleem, dat mogelijk een probleem vormt voor inheemse soorten en hun evenwicht. Aan de andere kant zijn Aziatische watervaranen echte reuzenhagedissen: ze vormen misschien geen echt gevaar, maar ze moeten zeker niet onderschat worden.
Discovery: it wasn't a comet that wiped out the dinosaurs, and it didn't come from Jupiter
Discovery: it wasn't a comet that wiped out the dinosaurs, and it didn't come from Jupiter
Story by Cédric DEPOND
About 66 million years ago, a cataclysmic event marked the end of the dinosaur era. This episode is linked to the impact of a giant asteroid in the Chicxulub region of Mexico. Until now, the exact nature and origin of this celestial body remained subject to debate.
A new study published in Science sheds light on these mysteries by revealing that this asteroid originated from the outer Solar System, beyond Jupiter, and not from a comet as some had supposed.

Researchers employed an innovative method to analyze samples of ancient sediments. These contain ruthenium, a chemical element absent from terrestrial rocks. By comparing the isotopes of ruthenium in the samples with those from different classes of meteorites, they determined that the asteroid that struck Earth was a carbonaceous type (type C). This indicates it formed beyond Jupiter's orbit, in a region where asteroids contain more carbon and volatile elements.
This discovery challenges the hypothesis put forward in 2021 by two Harvard researchers, who proposed that the Chicxulub impactor was a long-period comet. According to their theory, the comet was fragmented by the Sun's gravitational influence before a fragment collided with Earth. However, the new data confirm that the celestial object was indeed a carbonaceous asteroid, thus refuting the comet idea.
Ruthenium played a key role in this identification. In fact, the isotopes of this element allow for distinguishing type C asteroids, formed in the outer Solar System, from type S asteroids, which are more common and originate from the inner Solar System. The fact that the Chicxulub asteroid is type C is particularly significant, as most meteorites found on Earth are type S, formed in regions closer to the Sun.
The implications of this discovery extend beyond dinosaur history. According to Mario Fischer-Gödde, a geochemist at the University of Cologne and lead author of the study, better understanding the nature of asteroids that have impacted Earth over time could provide clues about the origin of water on our planet. He also suggests that if other mass extinctions were caused by type C asteroids, it would be essential to closely monitor this type of celestial object in the future, as they could pose a significant threat to life on Earth.

For decades, a massive anomaly sprawling across 1.2 million square miles on the Indian Ocean floor has baffled scientists. This phenomenon, known as the “gravity hole,” has sparked endless debate and curiosity. Read on as we uncover this mystery, officially named the Indian Ocean Geoid Low.
The Indian Ocean’s Gravity Anomaly So, what’s the deal with this vast region of the Indian Ocean that sits up to 106 meters below the global average sea level? It turns out there’s a significant dip in Earth’s gravity here. This gravitational anomaly has puzzled scientists for years, but recent studies are shedding light on its origins and linking it to deep geological processes.
Understanding the Geoid Low Geologists have a term for this “hole”—a geoid low, where Earth’s gravity is weaker than average. It might sound alarming, but it’s just a natural part of our planet’s gravitational landscape. Recent research suggests that molten rock plumes rising from deep beneath Africa are responsible for this phenomenon; these plumes are at the edge of an ancient sea bed.
Earth’s Shape and Gravitational Variation Ideally, Earth would have uniform gravity, but it’s not a perfect sphere. It’s flatter at the poles and bulges at the equator, causing variations in gravity. Different regions exert varying gravitational pulls based on the crust, mantle, and core mass distribution. Such complexity contributes to gravitational anomalies like the low geoid of the Indian Ocean.
The Potsdam Gravity Potato To visualize these gravitational tugs, scientists use gravity measurements from sensors and satellites to create models like the “Potsdam gravity potato.” The model highlights Earth’s gravitational highs and lows, helping scientists understand the mass distribution beneath the surface. It’s like taking off each layer of an onion, discovering more with every peel.
Discovery and Confirmation of the IOGL The Indian Ocean Geoid Low (IOGL) was discovered by Dutch geophysicist Felix Andries Vening Meinesz in 1948 during a ship-based gravity survey. Since then, subsequent shipboard expeditions and satellite measurements have confirmed its presence. This IOGL is the planet’s most prominent gravitational anomaly, covering over three million square kilometers.
Investigating the Origins Researchers Attreyee Ghosh and Debanjan Pal compared various computer models of the region’s formation over the past 140 million years. Each model used different variables for the convection of molten material within the mantle. Their goal? To pinpoint the cause of the IOGL. Their findings point to a distinctive mantle structure influenced by ancient geological events.
The Role of the Mantle and the African Blob The study suggests that the IOGL is due to a unique mantle structure combined with an adjacent disturbance under Africa known as the “African blob.” This large low-shear velocity province (LLSVP) consists of hot, low-density material, thought to be remnants from ancient seafloor slabs, which influence the region’s gravitational characteristics.
Connection to the Tethys Ocean Geologists believe Tethyan slabs, remnants of an ancient seafloor from the Tethys Ocean, form the African blob. Over 200 million years ago, the Tethys Ocean existed between the supercontinents Laurasia and Gondwana. As India moved northward, it created the Indian Ocean and left behind these geological traces.
Evolution and Persistence of the IOGL Around 20 million years ago, the geoid low probably formed its current shape as plumes began spreading through the upper mantle. The mantle material flow from the African blob sustains this anomaly. As long as these flows continue, the geoid low will persist.
Future Implications The IOGL will eventually dissipate when temperature anomalies cause it to move, which could take many millions of years. Studying this geoid low provides valuable insights into Earth’s internal processes and the dynamic nature of its mantle.
5.5 million years ago the Mediterranean dried out, with sobering lessons for humanity today – new research
What would happen if humans dried out the Mediterranean sea, turning it into a giant salt lake? Would its wildlife survive, and if so, how long would it take to recover?
These may seem like wildly theoretical questions, but not for Herman Sörgel, a Bavarian architect who dedicated much of his life to this exact project: building a giant dam across the Strait of Gibraltar, letting the Mediterranean dry up, and colonising the land reclaimed from the sea.
Sörgel organised lectures and documentaries and raised funds until the 1950s for a project which, he believed, would promote cooperation between Africa and Europe, and power both continents through gigantic hydroelectric megaprojects.
What he did not know was that his dream had already come true at the end of the Miocene era, 5.5 million years ago, as a simple result of natural forces.
When the Mediterranean disappeared
Since the 1970s, several generations of marine geologists and geophysicists have confirmed the existence of a one to three kilometre thick layer of salt buried throughout most of the deeper parts of the Mediterranean Sea.
This is almost a million cubic kilometres of salt that testify to a brief period when the Mediterranean was isolated from the rest of the world’s oceans – brief in the geological sense, as the episode lasted about 190,000 years
The culprit was not, of course, an eccentric German architect, but plate tectonics. The Mediterranean basin, trapped between two continents that today continue to move closer by up to two centimetres every year, was cut off from the Atlantic. Its waters quickly evaporated due to the region’s arid climate, leaving behind vast amounts of salt.
This episode, known as the Messinian salinity crisis (the Messinian being the last period of the Miocene), is the biggest extinction event suffered by the Earth since the meteorite that wiped out the flightless dinosaurs and ended the Mesozoic era 65 million years ago.

As a result, no geoengineering experiments are needed to answer our initial question: how resilient is marine life in the face of an environmental crisis of this magnitude?
The answer has just been published in the journal Science, in a study led by Konstantina Agiadi of the University of Vienna in collaboration with the Spanish National Research Council and 28 other scientists from 25 European institutes.
After gathering all Mediterranean fossil data from between 12 and 3.6 million years ago, the results suggest that native marine life was virtually extinct when the Mediterranean was cut off, and that subsequent recolonisation by Atlantic species gave rise to a Mediterranean fauna more similar to the one we find there today.
Native, extinct and migrant species
By statistically analysing information from more than 750 scientific papers, we were able to document 22,932 presences of a total of 4,897 marine species living in the Mediterranean. Before the crisis, 779 species could be considered endemic species (i.e. documented only in the Mediterranean). Of those, only 86 were still present after the salinity crisis. All the tropical corals that were abundant in the Mediterranean before this cataclysmic environmental change disappeared.

However, some apparently endemic sardine species managed to survive. The sirenian, a sea mammal related to today’s manatees and dugongs (also known as sea cows) also survived.
Because fossil records are limited and fragmented we cannot be certain that these species were all endemic, or that they would not have survived outside the Mediterranean, hence the value of basing our study on statistics from a large number of species. But for those that were endemic, where did they manage to survive, and what refuges did they find to avoid the radical increase in salt levels and temperature?
These questions remain unanswered, but we have been able to establish that changes in populations are the result of replacement by Atlantic species after the Mediterranean’s re-flooding, rather than rapid adaptation to the new hypersaline environment. In other words, life did not have enough time to adapt, and the extinct species were replaced by Atlantic species that migrated into the Mediterranean.
Several iconic species, such as the great white shark and the dolphin, only appeared in the Mediterranean after the crisis. Even more interestingly, the current richness of fauna in the western Mediterranean only came after the re-flooding – previously, the eastern Mediterranean (Ionian and Levantine Seas) had possessed a higher number of different species.
The impact of the Mediterranean’s isolation on its fauna and flora was catastrophic, destroying most of its ecosystems. Another significant finding from our research is that it took more than 1.7 million years for species numbers to recover. This slow recovery of the richness of Mediterranean ecosystems provides the first detailed quantification of how wildlife responds to an extinction event of this magnitude.
The Mediterranean’s biodiversity today is very high thanks to the presence of numerous endemic species. Our results suggest that this was also the case six million years ago, but that the vast majority of these endemic species disappeared when it was cut off from the Atlantic.
Perhaps another lesson learned from this study is that, however tempting it may be to believe that geoengineering projects can allow us to maintain our current rate of emissions and ecosystem destruction, the Earth’s geological past will reveal more than any experiment.
When the Mediterranean was reconnected to the Atlantic, it was repopulated by the huge reserve of species in the world’s oceans, yet it still took millions of years for the Mediterranean’s ecosystems to recover in terms of richness. No one knows yet how long it will take for marine life to recover from the kind of global-scale change that is currently underway.
Two astronauts marooned in space may sound like the plot of a Hollywood blockbuster, but for two NASA crew members, it is now a reality. Commander Barry Wilmore and pilot Sunita Williams are currently in limbo on the International Space Station (ISS).
They arrived in the Boeing Starliner spacecraft — the first test of the spaceship with astronauts. Wilmore and Williams were supposed to stay on the ISS for around eight days and return on the same spacecraft. But there is now debate about the safety of Starliner after it experienced helium leaks and thruster problems on its way to the ISS.
In the coming days, NASA and Boeing may decide to clear Starliner to carry the astronauts back to Earth. This means their stay might not last too much longer. But if officials decide against Starliner, the astronauts face waiting an additional six months in orbit before returning. So how do astronauts cope with a potential six-month wait for a lift home?
Part of the reason that waiting is difficult is that it distorts our sense of time. Think of the last time you were waiting for a delayed train, test results or a text from a potential new partner. Did it fly by or drag? For most people, time spent waiting crawls at a glacial pace. As a result, delays and periods of anticipation often feel much longer than they actually are.
Waiting slows our perception of time because it changes the amount of time that we spend thinking about time. During normal daily life, we often ignore time, and our brains have a limited capacity. If time isn’t important, we simply don’t think about it, and this helps it to pass quickly.
When we are waiting, our desire to know when the wait is over increases how much we think about time. This “clock watching” can make the minutes and hours feel like they are passing at a snail’s pace. Stress, discomfort and pain exacerbate this effect, meaning that waiting in difficult situations can seem even longer.
Waiting also slows our perception of time because it is what we do and how we feel. Normal life is busy and full of ever-changing activities and interactions. The sudden need to wait halts the flow of life, often leaving us with nothing else to do, thus increasing levels of boredom and frustration.
In general, time filled with activity passes more quickly. We all got a taste of this during COVID lockdowns. When we were stuck inside, unable to see friends and engage in normal daily activities, the loss of routine and distractions caused time to drag for many.
For the astronauts stuck on the ISS, anxiety about when they will return, limited opportunities for activities and fewer opportunities to contact friends and families combine to make their wait to return home feel significantly longer than six months — if it should come to that.
However, as academics who research the effects of time on human psychology and biology, our ongoing work with crew members at research stations in Antarctica aims to shed light on whether waiting in extreme environments is different to waiting during normal daily life.
A year in Antarctica
While being stuck for six months on the ISS may sound like many people’s worst nightmare, it is not uncommon for scientists to spend long periods isolated and confined in extreme environments. Every year, organizations such as the Instituto Antártico Argentino (which uses the Belgrano II Antarctic station), the French Polar Institute and the Italian Antarctic Programme, in cooperation with the European Space Agency (which all use Antarctica’s Concordia station), send crews of people for up to 16 months to conduct research on the frozen continent.
During the March to October polar winter, teams spend six months in near darkness – and from May to August, in complete darkness – facing outside temperatures of up to -60C, wind speeds of 160 km/h (100 mph) and storms which prevent almost all outdoor activity. Limited internet coverage can also prevent constant communication with the outside world.
For the last year, we have researched how life in Antarctica influences people’s experience of time. Each month, we asked crew members how time felt like it was passing in comparison to before their mission. Trapped on base, with limited contact with the outside world, you might expect time to drag. However, our results suggest the opposite may be true.
Analysis of crew members’ experiences indicated that being constantly busy with complex tasks such as scientific research helped the time to pass swiftly, according to 80% of crew responses. Only 3% of responses indicated that time actually dragged, and these reports occurred when nights were long, and there was little to do.
These experiences may provide hope for those stuck on the ISS. Like life in an Antarctic station, these NASA astronauts have busy and mentally demanding lives. These factors may help time to pass quickly.
However, a key factor of their wait may be their ability to tolerate the uncertainty of when they will return. Wilmore and Williams will spend their time in a space equivalent to the inside of a Boeing 747 plane. However, better information about “when” things will happen and “why” delays are being incurred can help people tolerate waiting and reduce its impact on their wellbeing.

Rogue planets may be more common than we thought, and they may form alone in the void in the same way stars do, suggests a recent study.
We think we know how the universe is structured: Moons orbit planets, and planets orbit stars. But rogue planets don’t play by the rules; they drift alone through the darkness, not bound to a star’s gravity. And these lonely rebel worlds may make up about 10 percent of celestial objects, not just rare flukes of nature.
The James Webb Space Telescope (JWST) peered into a nearby star cluster and found a handful of rogue gas giants — including one with its own disk of dust swirling around it. The results suggests that rogue planets may not only be worlds that got kicked out of their star systems, but worlds that coalesce out of clouds of interstellar gas in the same way stars do — just smaller.
Johns Hopkins University astrophysicist Adam Langeveld and his colleagues published their work in The Astronomical Journal.
This is JWST’s latest image of NGC 1333, a stellar cluster about 1,000 light years away, where new stars — and new rogue planets — are still being born.
STScI
Lonely Planets Club
Langeveld and his colleagues surveyed a cluster of stars called NGC 1333, which exists 1,000 light years away in the constellation Perseus, with JWST’s Near Infrared Imager and Slitless Spectrograph (NIRISS) instrument. They found six gas giants — each between five and 10 times more massive than Jupiter — drifting through space on their own, not orbiting a star. One of these lonely worlds even had a disk of dust orbiting it, as if in the process of forming its own little family of planets (or moons). And based on their observations, Langeveld and his colleagues say rogue planets, once thought to be rare flukes of nature, might make up about 10 percent of the objects in the cluster.
We know that stars form when dense clumps of gas and dust in clouds called nebulae collapse under their own gravity, creating enough heat and pressure at their centers to kickstart nuclear fusion. And we know that sometimes, a clump of material can form an object that’s just on the threshold of being able to start burning as a star, but doesn’t have quite enough mass to get there: a brown dwarf. But astronomers weren’t sure whether even smaller objects, like giant gas planets, could form the same way.
The team of astrophysicists used JWST “to search for the faintest members of a young star cluster, seeking to address a fundamental question in astronomy: how light an object can form like a star?” says Johns Hopkins University astrophysicist Ray Jayawardhana, the senior author of the recent paper, in a recent statement. “It turns out the smallest free-floating objects that form like stars overlap in mass with giant exoplanets circling nearby stars.”
The smallest rogue planet Langeveld and his colleagues spotted, a gas giant about 5 times the mass of Jupiter (or 1,600 times the mass of Earth, if you prefer), is an important clue. It sits at the heart of a swirling disk of gas and dust, which looks exactly like the disks that form around newborn stars, where material eventually coalesces into planets. That suggests that the planet probably formed like a star, just from a smaller cloud of gas and dust. And it may be forming its own miniature system, like Jupiter or Saturn with their swarms of moons.
In other words, rogue planets may not always be planets that formed in orbit around a star like our Sun, only to get kicked out of the star system by a close encounter with a sibling planet or a passing star (which may have happened at least once in our own Solar System’s history). Instead, they can apparently spawn all alone, from much smaller clouds of gas than the ones that form stars.
“This is important context for understanding both star and planet formation,” says Langeveld in a recent statement.
What’s Next?
Langeveld and his colleagues hope to learn more about these lonely planets’ atmospheres in their next round of observations with JWST. Once they have that information, they’ll compare the rogue gas giants’ atmospheres to brown dwarfs and to “normal” gas giants that orbit stars. That could offer clues about whether gas giants that coalesce alone in the middle of space contain a different mix of elements than those that form in the disks around newborn stars.
The astronomers also hope to find more objects like the small rogue planet with its own little protoplanetary disk. That could shed light on whether, or how, rogue planets might form their own systems of planets (or moons). Picture all the diverse worlds that orbit the gas giants in our Solar System — Jupiter’s icy moon Europa and volcanic hellworld Io, or Saturn’s Titan with its methane seas — orbiting a version of Jupiter all alone in deep space, unlit by any star, heated only by the tidal pull of their planet.
“The diversity of systems that nature has produced is remarkable and pushes us to refine our models of star and planet formation,” says Jayawardhana.
It feels like every few months, microplastics are cropping up someplace else they don’t belong: testicles, placentas, carotid artery plaque,lungs. These infinitesimally small plastic particles, which are smaller than 5 millimetersacross, have most recently been detected in brains, according to a new study.
A preprint study — which is a scientific study that has not yet been reviewed by other scientists for publication in a journal — was posted online in May by the National Institutes of Health looking at the amount of microplastics in human brain samples from autopsies. The study found that brains had higher concentrations of microplastics than other organs, and that these autopsy samples also had higher concentrations of microplastics than autopsy samples from a 2016 study. Though this paper is still under review to ensure the methods and findings are trustworthy, the key results of the study exemplify yet another vital organ affected by microplastics.
For the study, the authors examined livers, kidneys, and brains from autopsied cadavers. They found that concentrations of microplastics in the brain samples they examined “ranged from 7 to 30 times the concentrations seen in livers or kidneys.” They also found that brain samples collected and analyzed in 2024 contained significantly higher concentrations of microplastic, with over 3,000 micrograms per gram of human tissue in 2016 and over 4,800 micrograms per gram in 2024. Some samples ranged as high as more than 8,800 micrograms of plastic per gram of brain tissue.
We don’t know yet what effects, if any, microplastics could have on the brain, but this study does confirm that these bits of plastic can cross the blood-brain barrier, which is the protective membrane that helps regulate what molecules enter the brain from circulating blood.
“Based on our observations, we think the brain is pulling in the very smallest nanostructures, like 100 to 200 nanometers in length, whereas some of the larger particles that are a micrometer to five micrometers go into the liver and kidneys,” lead author of the study Matthew Campen, a toxicologist and professor of pharmaceutical sciences at the University of New Mexico in Albuquerque, told CNN.
While it seems like microplastics are omnipresent in today’s society, figuring out how to affect our health is key.
The team behind thefirst ever imageof a black hole can now observe the same celestial gargantuan with greater definition than ever before.
On Tuesday, the Event Horizon Telescope (EHT) team announced that their global network of radio telescopes, which turns Earth into one giant virtual telescope, can observe at a new radio frequency. This means a few things. First, the team can get crisper imagery of the supermassive black hole at the center of galaxy M87, which starred in the first ever image of a black hole, taken in 2017 and published in 2019. Second, having an additional frequency means the team can play with color.
“This new ‘color vision’ allows us to tease apart the effects of Einstein’s gravity from the hot gas and magnetic fields that feed the black holes and launch powerful jets that stream over galactic distances,” Sheperd “Shep” Doeleman, astrophysicist and Founding Director of the EHT, said in an announcement published Tuesday.
The supermassive black hole M87* seen two ways in two simulated images. The 345 GHz view is on the right, and represents the newest capability of the Event Horizon Telescope.

Two is better than one
Doeleman tells Inverse that supermassive black holes are busy places. Seeing two frequencies would reveal more of its organized chaos. The team has published simulation images to depict how the new frequency changes the view.
“When you have two separate frequencies, you’re able to tease apart different effects around the black hole,” Doeleman says.
Albert Einstein predicted that gravity bends all light, across all wavelengths, in the same way. Right around the black hole’s shadow, where gravity is so strong that not even light can reflect back out, data across both frequencies may look the same.
But farther away from the event horizon, other phenomena like the black hole’s jets of superheated plasma will look differently from one frequency to the next.
Seeing in color
Having two sets of information allows for color. The data from the telescopes is radio, a wavelength of light invisible to human eyes. The single color of existing EHT images are packed with information at 230 GHz. But now that EHT can take observations at 345 GHz, imagery specialists can add a new color to the golden ring. This will be exciting to view not only as a still image, but eventually, as a motion picture.
This composite simulated image from the Event Horizon Telescope shows how the supermassive black hole M87* might look at different radio frequencies of 86 GHz (red), 230 GHz (green), and 345 GHz (blue).
EHT, D. Pesce, A. Chael
Doeleman and other researchers hope the telescopes in the EHT network will be able to take not just two radio wavelengths at the same time, but eventually three.
“The EHT's successful observation at 345 GHz is a major scientific milestone,” Lisa Kewley, Director of the Center for Astrophysics | Harvard & Smithsonian, said in the announcement. “By pushing the limits of resolution, we’re achieving the unprecedented clarity in the imaging of black holes we promised early on, and setting new and higher standards for the capability of ground-based astrophysical research.”
A NASA Rocket Has Finally Found Earth’s Global Electric Field

A NASA Rocket Has Finally Found Earth’s Global Electric Field
Scientists have discovered that Earth has a third field. We all know about the Earth’s magnetic field. And we all know about Earth’s gravity field, though we usually just call it gravity.
Now, a team of international scientists have found Earth’s global electric field.
It’s called the ambipolar electric field, and it’s a weak electric field that surrounds the planet. It’s responsible for the polar wind, which was first detected decades ago. The polar wind is an outflow of plasma from the polar regions of Earth’s magnetosphere. Scientists hypothesized the ambipolar field’s existence decades ago, and now they finally have proof.
“It’s like this conveyor belt, lifting the atmosphere up into space.”
Glyn Collinson, Heliophysics Science Division, NASA Goddard Space Flight Center
The Space Age gained momentum back in the 1960s as the USA and USSR launched more and more satellites. When spacecraft passed over the Earth’s poles, they detected an outflow of particles from Earth’s atmosphere into space. Scientists named this the polar wind, but for decades, it was mysterious.
Scientists expect some particles from Earth to “leak” into space. Sunlight can cause this. But if that’s the case, the particles should be heated. The wind is mysterious because many particles in it are cold despite moving at supersonic speeds.
“Something had to be drawing these particles out of the atmosphere,” said lead author Collinson.
Collinson is also the Principal Investigator for NASA’s “Endurance” Sounding Rocket Mission. “The purpose of the Endurance mission was to make the first measurement of the magnitude and structure of the electric field generated by Earth’s ionosphere,” NASA writes in their mission description. Endurance launched on May 22nd, 2022, from Norway’s Svalbard Archipelago.
This image shows NASA’s Endurance rocket launching from Ny-Ålesund, Svalbard, Norway. It flew for 19 minutes to an altitude of about 780 km (484 mi) above Earth’s sunlit polar cap. It carried six science instruments and could only be launched in certain conditions to be successful. Image Credit: NASA/Brian Bonsteel.
“Svalbard is the only rocket range in the world where you can fly through the polar wind and make the measurements we needed,” said Suzie Imber, a space physicist at the University of Leicester, UK, and co-author of the paper.
Svalbard is key because there are open magnetic field lines above Earth’s polar caps. These field lines provide a pathway for ions to outflow to the magnetosphere.
This figure from the research shows Endurance’s flight profile and its path over Earth. The rocket had to fly near the open magnetic field lines that exist at Svalbard’s high polar latitudes. Image Credit: Collinson et al. 2024.
After it was launched, Collinson said, “We got fabulous data all through the flight, though it will be a while before we can really dig into it to see if we achieved our science objective or not.”
Now, the data is in, and the results show that Earth has a global electric field.
Prior to its discovery, scientists hypothesized that the field was weak and that its effects could only be felt over hundreds of kilometres. Even though it was first proposed 60 years ago, scientists had to wait for technology to advance before they could measure it. In 2016, Collinson and his colleagues began inventing a new instrument that could measure the elusive field.
At about 250 km (150 mi) above the Earth’s surface, atoms break apart into negatively charged electrons and positively charged ions. Electrons are far lighter than ions, and the tiniest energetic jolt can send them into space. Ions are more than 1800 times heavier, and gravity draws them back to the surface.
If gravity were the only force at work, the two populations would separate over time and simply drift apart. But that’s not what happens.
Electrons and ions have opposite electrical charges. They’re attracted to one another and an electric field forms that keeps them together. This counteracts some of gravity’s power.
The field is called ambipolar because it’s bidirectional. That means it works in both directions. As ions sink down due to gravity, the electrical charges mean that the ions drag some of the electrons down with them. However, at the same time, electrons lift ions high into the atmosphere with them as they attempt to leave the atmosphere and escape into space.
The result of all this is that the ambipolar field extends the atmosphere’s height, meaning some of the ions escape with the polar wind.
After decades of hypothesizing and theorizing, the Endurance rocket measured a change in electric potential of only 0.55 volts. That’s extremely weak but enough to be measurable.
“A half a volt is almost nothing — it’s only about as strong as a watch battery,” Collinson said. “But that’s just the right amount to explain the polar wind.”
Hydrogen ions are the most plentiful particles in the polar wind. Endurance’s results show that these ions experience an outward force from the magnetic field that’s 10.6 times more powerful than gravity. “That’s more than enough to counter gravity — in fact, it’s enough to launch them upwards into space at supersonic speeds,” said Alex Glocer, Endurance project scientist at NASA Goddard and co-author of the paper.
Hydrogen ions are light, but even the heavier particles in the polar wind are lifted. Oxygen ions in the weak electrical field effectively weigh half as much, yet they’re boosted to greater heights, too. Overall, the ambipolar field makes the ionosphere denser at higher altitudes than it would be without the field’s lofting effect. “It’s like this conveyor belt, lifting the atmosphere up into space,” Collinson added.
“The measurements support the hypothesis that the ambipolar electric field is the primary driver of ionospheric H+ outflow and of the supersonic polar wind of light ions escaping from the polar caps,” the authors explain in their paper.
“We infer that this increases the supply of cold O+ ions to the magnetosphere by more than 3,800%,” the authors write. At that point, other mechanisms come into play. Wave-particle interactions can heat the ions, accelerating them to escape velocity.
These results raise other questions. How does this field affect Earth? Has the field affected the planet’s habitability? Do other planets have these fields?
Back in 2016, the European Space Agency’s Venus Express mission detected a 10-volt electric potential surrounding the planet. This means that positively charged particles would be pulled away from the planet’s surface. This could draw away oxygen.
Scientists think that Venus may have once had plentiful water. However, since sunlight splits water into hydrogen and oxygen, the electric field could’ve siphoned the oxygen away, eliminating the planet’s water. This is theoretical, but it begs the question of why the same thing hasn’t happened on Earth.
The ambipolar field is fundamental to Earth. Its role in the evolution of the planet’s atmosphere and biosphere is yet to be understood, but it must play a role.
“Any planet with an atmosphere should have an ambipolar field,” Collinson said. “Now that we’ve finally measured it, we can begin learning how it’s shaped our planet as well as others over time.”
The Batagay megaslump is a result of the ground thawing and collapsing as Arctic temperatures rise.
It's an extreme case of a changing Arctic landscape accelerating the climate crisis.
A giant hole in the earth is breaking open the land in Siberia, and photos from space show it's growing rapidly.
It resembles a stingray, a horseshoe crab, or a giant tadpole. It started as a sliver, barely visible in declassified satellite imagery from the 1960s.
Declassified satellite imagery from 1965 shows the very beginnings of the hole growing in Siberia.
The hole tripled in size between 1991 and 2018, according to the US Geological Survey.
Satellite images from 1999 and 2017 show how much the Batagay megaslump has grown (and how much satellite imaging has improved). NASA Earth Observatory/Jesse Allen/Landsat data from the US Geological Survey
The Batagay crater, sometimes referred to as Batagaika or the "gateway to hell," represents a much larger, often invisible problem that affects the entire planet.
What is this hole in Siberia?
The Arctic is heating up faster than the rest of Earth, and that's quickly thawing the permafrost, which is a thick layer of soil that's permanently frozen — at least, it used to be.
The Batagay crater isn't actually a crater at all. It's the world's largest "retrogressive thaw slump," a pit that forms when permafrost thaw causes the ground to cave in, creating a landslide as the earth at its edges slumps into the pit.
There are thousands of thaw slumps across the Arctic. But the size of the Batagay "crater" has earned it the title of megaslump. It's named for the nearby town of Batagay.

"Permafrost is not the most, let's say, photogenic of subjects," Roger Michaelides, a geophysicist at Washington University in St. Louis, told Business Insider. "You're talking mostly about frozen dirt underground, which by definition you often can't see unless it's been exposed somehow, like in this megaslump."
That makes the Batagay pit a bit of a permafrost celebrity and an omen of what lies ahead.
The Batagay megaslump could help decode our planet's future
As permafrost thaws, all the dead plants and animals that have been frozen inside it for centuries start to decompose, belching carbon dioxide and methane into the atmosphere.
Those are powerful heat-trapping gases, which cause global temperatures to rise even more, triggering even faster permafrost thaw.
This vicious cycle could have dire effects. Permafrost covers 15% of the land in the Northern Hemisphere and contains twice as much carbon as the atmosphere.
One study estimated that permafrost thaw could emit as much planet-warming gases as a large industrial nation by 2100 if industries and countries don't aggressively rein in their own emissions today.
"There's a lot we don't know about this feedback loop and how it will play out necessarily, but the potential is there for very large changes to the climate system occurring over very, very fast geologic timescales," Michaelides said.
In short, permafrost thaw could quickly make the climate crisis much worse. But it's still a mysterious process. Studying extreme sites like the Batagay megaslump can help scientists understand permafrost thaw and see into the future.
In a study published in the journal Geomorphology in June, researchers used satellite and drone data to construct 3D models of the megaslump and calculate its expansion over time.
They found that about 14 Pyramids of Giza's worth of ice and permafrost had thawed at Batagay. The crater's volume increases by about 1 million cubic meters every year.
"These values are truly impressive," Alexander Kizyakov, the study's lead author and a scientist at Lomonosov Moscow State University, told BI in an email.
"Our results demonstrate how quickly permafrost degradation occurs," he added.
The researchers also calculated that the megaslump releases about 4,000 to 5,000 tons of carbon each year. That's about as much as the annual emissions from 1,700 to 2,100 US homes' energy use.
Michaelides said those numbers didn't surprise him, but they can help inform models of future permafrost thaw and emissions.
"I think there is a lot we can learn from Batagaika, not only in terms of understanding how Batagaika will evolve with time, but also how similar features might develop and evolve over the Arctic," Michaelides said. "Even if they're a tenth or a hundredth the size of Batagaika, the physics is fundamentally the same."

Zwarte gaten vormen een van de meest fascinerende en complexe mysteries van het heelal. We weten dat ze bestaan, maar we kunnen ze niet zien, behalve door de invloed die ze uitoefenen op de omringende ruimte, wat hun zoektocht complexer maakt. Daarom heeft het nieuwe project Black Hole Finder besloten om alle liefhebbers van de astronomie te betrekken bij de ontdekking van nieuwe zwarte gaten in het heelal. Hoe? Door middel van een smartphone-app: laten we eens kijken hoe het werkt!
Op zoek naar zwarte gaten
Met de Black Hole Finder, ontwikkeld door het Dutch Black Hole Consortium, kunnen liefhebbers een app gebruiken om astronomen te helpen zwarte gaten in het heelal te vinden. Het doel is in werkelijkheid veel complexer, namelijk het identificeren van kilonova’s, krachtige stellaire explosies van elektromagnetische straling die ontstaan wanneer twee ongelooflijk dichte objecten met elkaar in botsing komen. We hebben het dan over botsingen tussen twee neutronensterren of bijvoorbeeld tussen een neutronenster en een zwart gat. Maar waarom zouden we kilonova’s bestuderen?
Onderzoekers gebruiken het BlackGEM-netwerk van telescopen om de nachtelijke hemel af te speuren naar deze enorme explosies. Naast het identificeren van het moment van botsing tussen een neutronenster en een zwart gat, kunnen kilonova’s leiden tot de vorming van een nieuw zwart gat met stellaire massa. Het idee is simpel: door kilonova's te detecteren, kunnen nieuwe zwarte gaten worden geïdentificeerd. Mits je onderscheid kunt maken tussen echte en fake beelden, natuurlijk.

Enthousiastelingen die de Black Hole Finder-app gebruiken, kunnen helpen kilonova’s en dus potentiële nieuwe zwarte gaten te lokaliseren. De bijdrage van gebruikers is van fundamenteel belang, omdat sommige door telescopen gemaakte beelden echte explosies laten zien, terwijl andere vervormd kunnen zijn als gevolg van licht dat wordt gereflecteerd door satellieten en andere interferentie. Hoe onderscheid je echte beelden van fake? Op dit moment kunnen algoritmen voor kunstmatige intelligentie niet concurreren met menselijk ingrijpen, dus wordt het noodzakelijk om liefhebbers van de astronomie om hulp te vragen. Steven Bloemen, projectmanager bij BlackGEM, bevestigt:
Mensen zijn nog steeds veel beter in het identificeren van patronen dan onze algoritmes. Met behulp van de app kunnen burgers over de hele wereld helpen onze AI-algoritmes te trainen om onderscheid te maken tussen echte en fake bronnen en sneller de meest interessante kandidaat-fondsen te identificeren.
Het gebruik van de applicatie is zeer intuïtief: de gebruiker bekijkt drie afbeeldingen van hetzelfde deel van de hemel en moet vaststellen of dit een echte bron is of niet. Een spel van waar of niet waar, zo je wilt. Uiteraard biedt de app alle informatie om kilonova’s te herkennen, die meestal verschijnen als ronde en witte vormen, met een diameter van ongeveer 5-10 pixels.
Waar dient de Black Hole Finder voor
Zoals we in de inleiding al zeiden, is het niet eenvoudig om zwarte gaten te detecteren. Ten eerste zijn ze niet allemaal zoals Sagittarius A*, het superzware zwarte gat in het centrum van de Melkweg. Er zijn ook enkele middelzware zwarte gaten bekend, maar de meeste zwarte gaten hebben een stellaire massa en zijn dus vrij klein. Toch weten we dat ze kunnen ontstaan als gevolg van kilonova’s, explosies die veel helderder zijn dan klassieke nova’s maar veel minder helder dan supernova’s. Hoe kunnen we ze detecteren?
Er komen liefhebbers van de astronomie aan te pas, die experts kunnen helpen bij het analyseren van het hemelgewelf op zoek naar nieuwe zwarte gaten. Elke goed geïdentificeerde kilonova stelt astronomen in staat om hun onderzoek te beperken tot veel kleinere delen van de ruimte. En we weten: het vinden van een zwart gat is niet eenvoudig, maar met de hulp van iedereen is het vandaag de dag iets gemakkelijker.
Are UFOs in the Bible? Exploring the Link Between Angels and Extraterrestrials
Are UFOs in the Bible? Exploring the Link Between Angels and Extraterrestrials
The intersection of religious belief and extraterrestrial life has long intrigued both theologians and enthusiasts of the unexplained. This curiosity often leads to the question: could the Bible contain references to what we now describe as UFOs or extraterrestrial beings? A recent discussion, featuring U.S. Congressman Tim Burchett and theologian Dr. Paul Thigpen, delved into this very topic, exploring the possibility that some biblical accounts could be interpreted as encounters with non-human intelligence, perhaps even extraterrestrial.
Biblical References to Anomalous Phenomena
Several passages in the Bible describe events that, to a modern reader, might seem reminiscent of UFO sightings. For example, the book of Ezekiel recounts a vision in which the prophet sees a “whirlwind coming out of the north, a great cloud with a raging fire engulfing itself” (Ezekiel 1:4). Within this cloud were creatures with an extraordinary appearance, leading some to speculate whether this could be an ancient description of a UFO encounter.

Similarly, the account of Elijah being taken up into heaven in a “whirlwind” with “chariots of fire” (2 Kings 2:11) has also been cited as a possible reference to extraterrestrial technology. The imagery used in these passages—wheels within wheels, flying chariots, and bright lights—bears a striking resemblance to descriptions of unidentified flying objects in modern times.
Theological Interpretations
Congressman Burchett, a devout Christian, expressed that he has no difficulty reconciling his faith with the possibility of extraterrestrial life. He argues that the vastness of God’s creation could easily encompass other life forms beyond Earth, and that such beings might have been referenced in the Bible using the language and understanding of the time. For Burchett, the idea that Ezekiel’s vision could describe a UFO does not weaken his faith; rather, it broadens his perspective on the universe’s complexity.
Dr. Paul Thigpen, on the other hand, approaches the subject with caution. He acknowledges that the Bible does describe non-human intelligences, such as angels and demons, but he is hesitant to equate these beings with extraterrestrials as understood in contemporary UFO lore. Thigpen emphasizes that biblical references to angels and other supernatural entities should be interpreted within the context of their religious significance, not necessarily as evidence of alien encounters.
The Debate Over Angels and Aliens
The conversation between Burchett and Thigpen highlights a broader debate within both religious and UFO communities: are angels and other biblical beings simply manifestations of divine power, or could they be visitors from other worlds? The traditional Christian view holds that angels are purely spiritual beings created by God, distinct from any physical extraterrestrial life forms. These beings do not have bodies and do not exist within our space-time in the way that humans or hypothetical aliens might.
However, the overlap between descriptions of angels and modern UFO encounters has led some to speculate that biblical accounts could be ancient interpretations of alien visitations. This theory posits that the “angels” seen by biblical figures might have been beings from another planet, whose advanced technology and abilities were interpreted as divine or supernatural.
UFOs and the Vatican
The discussion also touched on the Catholic Church’s stance on extraterrestrial life. Historically, the Vatican has shown a keen interest in astronomy, and some Popes have even entertained the possibility of life beyond Earth. Pope John Paul II, when asked about aliens, responded that “they are God’s children too,” suggesting an openness to the idea that other intelligent beings could exist within God’s creation.
Additionally, there have been claims, such as those mentioned by David Grusch, a former U.S. intelligence officer, that the Vatican might have been involved in secret activities related to UFOs, including the transfer of alleged extraterrestrial technology during World War II. While these claims remain unproven, they add another layer of intrigue to the conversation about religion and extraterrestrial life.
Conclusion: A Broader Perspective on Faith and the Universe
The idea that the Bible might contain references to UFOs or extraterrestrials is a fascinating one that challenges traditional interpretations of religious texts. For some, like Congressman Burchett, this possibility enhances the awe of God’s creation, suggesting that humanity is not alone in the universe. For others, like Dr. Thigpen, it is important to maintain a distinction between spiritual beings as described in the Bible and the physical entities that might exist elsewhere in the cosmos.
Ultimately, the discussion about angels, aliens, and UFOs in the Bible invites believers and skeptics alike to explore the mysteries of faith and the universe with an open mind. Whether these biblical passages are read as metaphorical, spiritual, or literal accounts, they continue to inspire curiosity and wonder about our place in the vastness of creation.
Giant Low-Frequency Scan Searches for Aliens in 2,800 Galaxies
The search for extraterrestrial intelligence (SETI) has fascinated us for decades. Now a team of researchers have used the Murchison Widefield Array in Australia to scan great swathes of sky for alien signals. Unusually for a SETI project, this one focussed attention on 2,800 galaxies instead of stars within our own. They have been on the lookout for advanced civilisations that are broadcasting their existence using the power of an entire star. Alas they weren’t successful but its an exciting new way to search for alien intelligence.
Our first attempts to search for alien intelligence began back in 1960 with Project Ozma. It was led by astronomer Frank Drake and used the 85 foot radio telescope at Green Bank in West Virginia. The aim was to try and detect alien radio signals from Epsilon Eridani and Tau Ceti, should they have existed. Alas they found nothing but it marked the first step in a scientific approach to search for extraterrestrial intelligence. Typically SETI tends to focus on electromagnetic signals such as radio waves an in particular unusual patterns that could suggest intentional communication.

This recent attempt to try out a new approach was led by Dr Chenoa Tremblay of the SETI Institute and Prof. Steven Tingay from the Curtin University. The approach was to utilise the magnificent field of view of the Murchison Widefield Array (MWA) which allows one observation to cover 2,800 galaxies. Among them, there are 1,300 galaxies that we know the distance too. The MWA in Western Australia utilises low frequencies (100MHz) to probe the distant galaxies.
By searching these galaxies for signs of alien signals we are actually looking for advanced civilisations. It’s one thing to be able to send radio signals across interstellar space, indeed we have been doing that for decades since the advent of radio communication. As radio signals propagate across space, they weaken and certainly could not traverse the immense distances between the galaxies. It’s just possible that advanced civilisations might have the technology to harness the power of their Sun and perhaps other stars in their galaxy to send signals powerful enough to travel the millions of light years between galaxies.
I quite love the idea of advanced civilisations that may have developed the technology to transmit ‘technosignatures’ or signs of alien technology across the Universe but alas the study did not find any. Queue sad emoji 🙁 It did however provide valuable insight into just how we may be able to widen our search for alien intelligence beyond the Milky Way.
The MWA uses thousands of dipole antennae that are spread across several kilometres giving it a wide 30 degree field of view. It has been designed to operate between 70 and 300 MHz allowing it to participate in studies of the early universe, mapping the cosmos, and detecting solar activity. It helped advance radio and interferometry technology facilitating the development of the Square Kilometre Array.

Using MWA and other radio installations to study the properties of stars and galaxies also allows for the search for technosignatures. It’s a new approach and it highlights the importance of continuing the development of new technology to open up new ways to search for ET.
ESA Cluster Satellite to Reenter in Early September
The first of a set of groundbreaking Cluster satellites is set for a controlled reentry next week.
The European Space Agency is paving the way in controlled reentry technology. ESA recently announced that plans to terminate the first of four Cluster satellites is about to come to fruition in early September, with the reentry of Salsa.
The Reentry
Salsa is one of four dance-themed Cluster satellites. The other three are Rumba, Samba and Tango. ESA controllers used the remaining thruster fuel on the spacecraft back in January to lower the perigee of the mission down to around 100 kilometers, which will assure destructive reentry for the 550 kilogram satellite over the South Pacific on or around September 8th. The area the satellite will meet its demise is known as ‘Point Nemo’ or the Pacific Ocean Uninhabited Area. The region has seen several large reentries over the years, including the Mir space station and ESA’s Automated Transfer Vehicle. The region will likely see the demise of the International Space Station sometime around 2030.

“By studying how Salsa burns up, which parts might survive, for how long and in what state, we will learn much about how to build ‘zero debris’ satellites,” says Tim Flohrer, (ESA-Space Debri Office) in a recent press release.

A Pioneering Mission
ESA designed the Cluster mission to explore space weather interactions with the Earth’s magnetic environment as the four spacecraft fly in a tetrahedral configuration through the planet’s magnetosphere. The four spacecraft fly out to a distant apogee of about 117,000 kilometers (over three times farther out versus geosynchronous orbit), and orbit the Earth once every 54 hours.

Launched in the summer of 2000, the Cluster satellites had a 5-year nominal mission, which lasted well over two decades. The missions have since proven to be pioneers in space weather research. The mission also escaped glitches and software failures over the years, including a bug requiring a “dirty hack” in 2010. Cluster II was also a replacement for the original set of Cluster satellites, which were lost on the inaugural launch of the Ariane-5 rocket on June 4th, 1996 from the Kourou Space Center. The mission ended in an explosion 37 seconds after liftoff.

Controlling Reentries
This sort of ‘targeted reentry’ for a long duration mission is one of the first of its kind for ESA. The zero-debris conclusion to the mission exceeds international standards. Furthermore, it also addresses issues surrounding the mitigation of debris in low Earth orbit. On Earth, ESA’s worldwide Estrack network will follow Salsa during its final orbits, and an airborne campaign is underway to spot the final reentry. ESA made a similar effort to image the Aeolus satellite in 2023, shortly before reentry.
Engineers will apply a similar technique to the SMILE (Solar wind Magnetosphere Ionosphere Link Explorer) and Proba-3 missions. These are also set to enter a similar far-ranging orbit around the Earth. SMILE is the follow-on mission to Cluster, and is launching in late 2025. ESA will launch the Proba-3 solar observatory next month. The mission will feature a free-flying, solar eclipsing disk.
You can spot the cluster satellites including Salsa on their final days. Salsa is COSPAR ID 2000-041A/26411in the NORAD satellite catalog, and listed in Heavens-Above. The satellites reach naked eye visibility on a good perigee pass.
After the demise of Salsa, Rumba will also reenter in November of next year, followed by Tango and Samba in August 2026.
While this is the ‘Last Dance’ for Salsa, the efforts to study space weather and come to terms with space debris continue.
