'Insanse' clip showing UFO flying at street level through Iran leaves locals baffled
'Insanse' clip showing UFO flying at street level through Iran leaves locals baffled
Locals in Tehran, Iran, were left baffled and shocked after something that look remarkably like a UFO was seen flying over their in four places across the major city.
It could be a UFO, or maybe not(Image: Reddit/YouTube)
A video of what appears to be a UFO flying at street level in Iran has left locals baffled.
The circular object, which appears to be made up of three rings of around 20 lights, was seen flying through the air at the end of May. The clip, posted on social media site Twitter/X sees locals staring at the object hovering no more than around five metres above their heads.
It took place in Tehran, and has left users on social media divided, with many claiming that it could be a real UFO. It was seen in four separate areas, and one clip shows it being accompanied by a whirring noise while flying in a straight line.
One person on Reddit claimed: “We got mfs testing actual bodies in Peru and US colonels telling us the interdimensional karma aliens are real. At this point, there’s no reason not to believe or take these things seriously.”
While another raged: “I believe it. UFOs are real. End of the day, it’s up to us. We believe the lying government and accept the matrix, or we believe our eyes, hearts, and common sense? I choose heart and truth.” And a third commented: “Nothing will convince people until we all see a massive thing coming out with our own eyes.”
'It could be real,' said one web sleuth(Image: Reddit/YouTube)
However, some did post their own theories, with one bloke on Twitter/X claiming that it could have been a “drone swarm,” while others pointed to the fact that the object had “no reflection” on any buildings it flies past. The videos also all appear to have had artificial digital zoom applied, which seems to be a massive red flag to web sleuths.
“Artificial digital zoom on the second video (made during editing to make it “more real”), I can see it from miles away,” one wrote.
And a second mused: “I don't know. I don't think I could know with video nowadays. Unless a mass arrival began. Otherwise, the technology of video editing has kinda negated the ability of basic ufo videos to show proof.”
Well, as always, the truth remains out there . . . somewhere.
The South Pole-Aitken Basin on the lunar far side is one of the largest and oldest impact features in the Solar System. It’s easily seen in the elevation data. The low center is dark blue and purple. Mountains on its edge, remnants of outer rings, are red and yellow.

The solar wind is a constant flow of radiation and particles from the Sun. Earth’s magnetic field acts as a shield.
In contrast, the Moon has no magnetic field and a very tenuous atmosphere, called the exosphere.
When the solar wind hits the Moon, the surface reacts, kicking up secondary particles.
These particles may be positively or negatively charged or have no charge at all.
While the positively charged particles have been measured from orbit before, measuring negative particles was a challenge.
Negative ions are short-lived and cannot make it to orbit. This is why ESA scientists needed to operate their instrument close to the lunar surface.
“This was ESA’s first activity on the surface of the Moon, a world-first scientifically, and a first lunar cooperation with China,” said Neil Melville, ESA’s technical officer for the NILS experiment.
“We have collected an amount and quality of data far beyond our expectations.”
“These observations on the Moon will help us better understand the surface environment and act as a pathfinder to explore negative ion populations in other airless bodies in the Solar System, from planets to asteroids and other moons,” said Dr. Martin Wieser, NILS principal investigator.
Chang’e-6 landed successfully in the South Pole-Aitken Basin on the far side of the Moon known on June 1, 2024.
NILS started to collect science data 280 min after landing. The first data collection period lasted for 23 min, until the instrument reverted to low voltage. A few more rounds of data collection followed between communications blackouts and reboots.
“We were alternating between short bursts of full-power and long cooling-off periods because the instrument was heating up,” Melville said.
“The fact that it stayed within its thermal design limits and managed to recover under extremely hot conditions is a testament to the quality of the work done by the Swedish Institute of Space Physics.”
Hoe slim is de bij? “Ze hebben een eigen persoonlijkheid, emoties, unieke taal en kunnen tellen”
Je zal er waarschijnlijk zelden bij stilstaan als je er eentje ziet voorbijzoemen, maar de bij is een ingenieus diertje. Gedragsbioloog Lars Chittka (Queen Mary University) neemt ons mee in het wonderbaarlijke brein van het insect. Hoe zitten hun hersenen in elkaar? Hoe intelligent zijn ze echt? En hebben ze een persoonlijkheid? Ontdek hier alles wat je nog niet wist over de bij.
In vergelijking met de hersenen van de mens (86 miljard hersencellen) zijn die van de bij maar klein. Het insect komt net verder dan een miljoen. Maar volgens gedragsbioloog Lars Chittka mogen we het beestje niet onderschatten. “Zijn elegante miniatuurhersentjes zijn biologische voorspellingsapparaten, voortdurend op zoek naar nieuwe mogelijkheden. Ook ’s nachts.’’
Na uitgebreid wetenschappelijk onderzoek dicht de wetenschapper in zijn boek ‘Het bewustzijn van de bij’ de insecten eigenschappen toe waarbij we als mens nauwelijks stilstaan. “Bijen zijn slim, hebben een eigen persoonlijkheid, herkennen bloemen en menselijke gezichten, communiceren via een eigen taal, vertonen emoties, kunnen tellen en gebruiken eenvoudige gereedschappen.”
Chittka, verbonden aan het Research Centre for Psychology van de Queen Mary University in Londen, nodigt iedereen uit om zich in te leven in het bestaan van de bij. “Stel je voor dat je een uitwendig skelet hebt – als een harnas van een ridder. Daaronder zit geen huid. Je spieren staan in directe verbinding met het harnas. Je kunt vliegen, hebt een gezichtsveld van 300 graden en je ogen verwerken veel sneller informatie. Je kunt ook ultraviolet licht zien en beschikt over een magnetisch kompas. Met de uitsteeksels op je hoofd kun je elektrische velden proeven, ruiken, horen en bespeuren. Informatie sla je op en gebruik je als het van pas komt”, schetst de gedragsbioloog.
Een bij kan met zijn voelsprieten tegelijk ruiken, proeven én horen.
Lars Chittka
Chittka is vooral onder de indruk van de multifunctionele voelsprieten van de bij: “Wij mensen hebben onze zintuigen van zicht, gehoor, geur en smaak netjes verpakt in compleet verschillende zintuigen. Daarom kunnen we niet proeven met onze voeten. Maar stel je voor dat je met je vingertoppen tegelijkertijd zou kunnen ruiken, proeven, horen en elektrische lading meten, zoals een bij met zijn voelsprieten doet.” Het meten van elektrische lading is voor een bij erg nuttig. Vliegende bijen zijn positief geladen, terwijl bloemen letterlijk geaard zijn – en dus negatief geladen. “Wanneer een bij een bloem bezoekt, zorgt de elektrische ladingsoverdracht ervoor dat de bloem tijdelijk positiever geladen wordt. Dat vertelt andere bijen dat de bloem onlangs is bezocht en is leeggezogen, geen nectar meer bevat.”
De intelligentie blijkt ook uit de ratenbouw van honingbijen. Hun dubbelzijdige zeshoekige raten is een indrukwekkende truc om ruimte te besparen. Om de vloeibare honing er niet uit te laten lopen worden de raten onder een hoek gebouwd. Dat bijen zich daarbij niet alleen laten leiden door instinct, bleek uit een experiment aan boord van de Space Shuttle Challenger in 1984. “De honingbijen brachten een hele week door zonder zwaartekracht. Ze leerden niet alleen om te vliegen onder dergelijke omstandigheden, maar ze bouwden hun vertrouwde honingraat met cellen van normale afmetingen”, aldus Chittka. De honingbijen pasten zich moeiteloos aan aan omstandigheden die ze nog nooit hadden meegemaakt.
Dat bijen net als duiven een zogeheten thuisrichtingsgevoel hebben, staat buiten kijf. Bijen maken daarbij gebruik van ‘geheugenfoto’s’: ze leggen een rijke bibliotheek aan van ruimtelijke herinneringen van hun leefomgeving.
Ruimtelijke oplossingen
De nog onbeantwoorde hamvraag is of bijen cognitieve kaarten hebben, die hen niet alleen in staat stellen om markeringen in het landschap of routes te onthouden, maar ook om nieuwe ruimtelijke oplossingen te berekenen op basis van die herinneringen zoals nieuwe kortere routes tussen bekende locaties. Experimenten met radartracking hebben in elk geval vastgesteld dat bijen zoeken naar korte fourageerroutes tussen bronnen vol nectar. Na het uitproberen van mogelijke routes werd de totale reisafstand met 80 procent ingekort. “Zelfs zeer ervaren bijen die de optimale route al hadden gevonden, bleven met tussenpozen experimenteren met nieuwe oplossingen”, aldus de Duitse gedragsbioloog die zelf onderzoek doet naar cognitieve vaardigheden van de bij.
Om met elkaar te communiceren, gebruiken bijen niet alleen de voelsprieten. Zij kwispeldansen om locaties van nectarrijke bloemlocaties aan elkaar door te geven, of een geschikte plek voor een nieuw thuis kilometers verderop. Deze ‘danstaal’ is fascinerend. “Hoe langer de dans, hoe beter de locatie. Als dansers andere dansers tegenkomen die een andere locatie aangeven, dan zullen ze proberen die dansen te verstoren met stopsignalen die ze geven met kopstootbewegingen”, legt Chittka uit.
Het brein van bijen roept nog veel vragen op, maar er bestaat overeenstemming over een basisbouwplan. “Net als bij ons zijn de hersenen van een bij bilateraal en symmetrisch geordend. Het grootste en belangrijkste deel is het ‘protocerebrum’, de voorhersenen. Het bevat de optische kwabben die informatie van de samengestelde ogen verwerken, en de paddenstoellichamen met belangrijke functies voor het verwerken van informatie uit meerdere zintuigen.” Hij noemt de paddenstoellichamen de ‘harde schijf’ van de bij, met een extreem grote geheugencapaciteit.
Een andere belangrijke taak is weggelegd voor het zogeheten centrale complex. Het bevat een geavanceerd navigatiesysteem, verzamelt informatie over afstand, richting en oriëntatiepunten. “Daardoor kan een bij die langs een kronkelig pad naar een nieuwe bloemen met nectar heeft gezocht, bijvoorbeeld direct naar huis terugkeren, waarbij gegevens over alle afgelegde afstanden en hoeken die langs het uitgaande pad zijn gedraaid, worden gebruikt.”
Persoonlijkheden
Dat bijen dezelfde genen hebben, wil niet zeggen dat zij dezelfde ‘persoonlijkheid’ hebben. Subtiele zintuiglijke verschillen bepalen bijvoorbeeld dat informatie door de ene bij anders wordt opgeslagen en gebruikt dan door een andere. Niet alle variatie tussen individuele bijen is ook erfelijk bepaald. Onderzoek wijst uit dat sommige bijen agressiever zijn dan andere, sommige werken harder, zijn slimmer of reageren voorzichtiger dan andere. “Net zoals er ‘persoonlijkheidsverschillen’ zijn tussen individuele bijen, kunnen er ook dergelijke verschillen zijn tussen kolonies van sociale bijen.”
Formeel bewijs voor een bewustzijn van bijen levert Chittka niet, maar het bewijs voor een op zijn minst eenvoudige vorm van bewustzijn stapelt zich wel op, meent hij. “Maar het bewustzijn van bijen zou wel eens heel anders kunnen zijn dan dat van mensen. Misschien hebben zij unieke emotionele toestanden die gepaard gaan met de opwinding van het zwermproces of de sensatie van het ontdekken van een bijzonder nectarrijk bloemtype. Daar moet nog meer onderzoek naar gebeuren.”
Volgens Chittka is het alleszins belangrijk om de bijen te koesteren. “We hebben ze nodig om onze gewassen te bestuiven. We maken onder meer kaarsen van hun was. En we eten al eeuwen van hun honing. We hebben dus veel aan de bijen te danken.”

Astronauts are Practicing Lunar Operations in New Space Suits

Astronauts are Practicing Lunar Operations in New Space Suits
Through the Artemis Program, NASA will send astronauts to the lunar surface for the first time since 1972. While the challenges remain the same, the equipment has evolved, including the rocket, spacecraft, human landing system (HLS), and space suits. In preparation for Artemis III(planned for September 2026), NASA recently conducted a test where astronauts donned the new space suits developed by Axiom Spaceand practiced interacting with the hardware that will take them to the Moon.
These new suits, the Axiom Extravehicular Mobility Unit (AxEMU), were developed specifically for the Artemis III mission. The day-long test took place on April 30th at SpaceX headquarters in Hawthorne, California, where astronaut Doug “Wheels” Wheelock and Axiom Space astronaut Peggy Whitson interacted with a full-scale model of the SpaceX Starship Human Landing System (HLS). This was the first time astronauts trained in pressurized spacesuits and conducted mock operations with the HLS hardware.
The test provided valuable feedback on theStarship HLSand the AxEMU spacesuits for NASA and its commercial partners. It also gave astronauts a chance to gauge the suits’ range of motion and to get a feel for the interior of the Starship HLSand its mechanical systems. Said Logan Kennedy, lead for surface activities in NASA’s HLS Program, in a NASA press statement:

“Overall, I was pleased with the astronauts’ operation of the control panel and with their ability to perform the difficult tasks they will have to do before stepping onto the Moon. The test also confirmed that the amount of space available in the airlock, on the deck, and in the elevator, are sufficient for the work our astronauts plan to do.”
The test consisted of Wheelock and Whitson practicing putting on and taking off the spacesuits – which included the suit’s Portable Life Support System (PLSS) – in the Starship HLS‘ full-scale airlock. Since the Artemis III astronauts will need to put the suits on with minimal assistance, this test allowed NASA to test how easily the suits are to get in and out of. The suits were then pressurized and powered up, and Wheelock and Whitson began interacting with the mobility aids (handrails and straps) and control panel in the airlock.
They then walked from the airlock deck to the HLS elevator, which will take the Artemis III astronauts and their equipment to the lunar surface to conduct extravehicular activity (EVA). Though the tasks were routine, they validated the spacesuit design and brought NASA one step closer to achieving its goals through the Artemis Program. As Amit Kshatriya (NASA’s Moon to Mars program manager) expressed:
“With Artemis, NASA is going to the Moon in a whole new way, with international partners and industry partners like Axiom Space and SpaceX. These partners are contributing their expertise and providing integral parts of the deep space architecture that they develop with NASA’s insight and oversight. Integrated tests like this one, with key programs and partners working together, are crucial to ensure systems operate smoothly and are safe and effective for astronauts before they take the next steps on the Moon.”
Wheelock and Whitson tested the agility of the spacesuits by conducting movements and tasks similar to those necessary during lunar surface exploration on Artemis missions. Credit: SpaceX
Putting the spacesuits through rigorous testing is necessary since the Artemis III mission will include EVAs in space and on the lunar surface. The four-person crew will launch aboard an Orion spacecraft atop NASA’s Space Launch System (SLS) while the Starship HLS launches separately and refuels in orbit. The Orion spacecraft will rendezvous and dock with the HLS in lunar orbit; two astronauts will transfer aboard and then take the HLS to and from the lunar surface. The AxEMU suits are designed to provide greater flexibility and accommodate a wider range of astronauts.
This is in keeping with NASA’s commitment to diversity, equity, and inclusion in its astronaut corps. Despite delays, things are undeniably coming together for Artemis III!
A Mission to Uranus Could Also be a Gravitational Wave Detector
Despite being extraordinarily difficult to detect for the first time, gravitational waves can be found using plenty of different techniques. The now-famous first detection at LIGO in 2015 was just one of the various ways scientists had been looking. A new paper from researchers from Europe and the US proposes how scientists might be able to detect some more by tracking the exact position of the upcoming Uranus Orbiter and Probe (UOP).
Initially suggested by NASA’s Planetary Science and Astrobiology Decadal Survey, UOP will be the first mission to Uranus since Voyager visited the system in 1986. When it finally arrives in 2044, after a 2031 launch date, it will be almost 60 years since humanity last had an up-close look at the Uranian system.
But 13 years in transit sure is a long time. Part of that time will be spent getting a gravitational boost from Jupiter, but most will be spent coasting between planetary bodies. And that much time spent in between planets is what the paper’s authors want to utilize to do non-Uranian science.
Fraser has long been a proponent of returning to Uranus, as he explains here.
Gravitational waves can disrupt the fabric of space-time, causing discernible distortions, especially over long distances. If the instruments in question are sensitive enough, the massive distance between UOP and the Earth would be a viable way to detect them.
This isn’t the first time using the distance between a spacecraft and Earth has been considered for detecting gravitational waves. Pioneer 11, Cassini, and a triangulation of Galileo, Ulysses, and Mars Orbiter all had entertained suggestions of being utilized for gravitational wave detection while on their journey to their final destinations. However, the equipment they were designed with was not sensitive enough to pick up the minute fluctuations required for an actual detection.
UOP will have the added advantages of decades of improved equipment, especially communications and timing electronics, which are critical to any gravitational wave detection. It also benefits that we’ve already officially detected a gravitational wave, so we know at least what to look for.
Long distance communication is hard, as Fraser explains in this video, but it’s also key to capturing data on gravitational waves.
The underlying mechanism is simple enough – consistently track the exact established position of UOP during its 13-year cruise to Uranus and cross-reference any anomalies in its position against what could be expected from known causes. These include the gravitational pull of some of the planets, or even asteroids, and solar radiation pressure on the spacecraft itself. As the authors note, some or even all of these could impact the spacecraft’s exact position; for the calculations to work effectively to find gravitational waves, better accounting for what, if any, impact they have must be completed.
But there is another potentially scientifically interesting cause of slight positional drift for the UOP: ultra-light dark matter. In theory, UOP could be used to test or even directly detect a form of dark matter known as ultra-light dark matter if it happens to exist in the solar system. Theorists have numerous models showing how it would work if it did exist. UOP could also use the same sort of exact positional calculation to contribute to that scientific research.
Best of all, UOP can do all this with literally no change to its primary functional mission – exploring the Uranian system. All that would have to be changed about the mission would be to update Earth with consistent positional data about once every 10 seconds for the duration of the 13-year trip to UOP’s final destination. Suppose there’s a chance that those more frequent check-ins with home could help detect gravitational waves or potentially dark matter. In that case, it seems well worth the consideration of the UOP mission planners – but it remains to be seen whether it will be included or not. The paper’s authors have made a persuasive argument about why it should be.
If aliens actually crashed here on Earth, what would happen?
Would the debris, and the aliens themselves, vanish behind a massive government cover-up, only to emerge as classified military technology years later? Or would altruistic civilian scientists work together to study the alien artifacts for the good of humanity?
These questions seem like fodder for very trope-y science fiction, but last week, a former U.S. Air Force intelligence officer told Congress last week, with a straight face, that an unnamed source had told him that the U.S. Department of Defense (or possibly its contractors) has debris and “nonhuman biologics” from a crashed UFO.
To answer these suddenly relevant questions, Inverse spoke with Greg Eghigian, a Pennsylvania State University historian and bioethicist who specializes in the study of UFOs.
NASA and the Department of Defense have been paying much more attention to Unidentified Anamolous Phenomena, or UAPs, in recent years.

WHO OWNS CRASHED UFOS?
If a flying saucer crashes in Oklahoma tomorrow, just for example, what happens next?
No law or treaty spells out who gets to claim the spaceship or alien remains. The U.S. and several other countries have laws about who owns meteorites (spoiler alert for U.S. readers: if the meteorite falls on private land, it belongs to the landowner; on public land, it depends) and even debris from human-made spacecraft re-entering Earth’s atmosphere (you can’t collect rocket parts in Florida, for example). Other laws even spell out who’s liable if a de-orbiting satellite crashes on someone’s house. At the moment, though, there’s nothing on the books about who technically owns a flying saucer that crashes on U.S. soil.
Senators Chuck Schumer and Mike Rounds are hoping to change that with an amendment to the National Defense Authorization Act. Their amendment, if it passes, would (among other things) give the U.S. federal government “eminent domain over any and all recovered technologies of unknown origin (TUO) and biological evidence of non-human intelligence (NHI) that may be controlled by private persons or entities in the interests of the public good.”
“I think the sense is that the government, particularly the military, would be the key entity that would take on this stuff,” Eghigian tells Inverse. “I don't think civilian scientists would be getting first dibs on this. I think they would be out of the loop.”
The U2, SR-71, A-12, B-2 and F117 were flight tested at the Air Force’s Groom Lake facility in Nevada, better known as Area 51.
ROGER HOLDEN/STOCKBYTE UNRELEASED/GETTY IMAGES
COULD THE GOVERNMENT REALLY KEEP A CRASHED UFO A SECRET?
Does that mean the Department of Defense would whisk the crash debris (and the “nonhuman biologics,” as former Air Force intelligence officer David Grusch recently described it to Congress) away to a top-secret bunker, never to be spoken of again?
“To start with, I think there's no question that the first people on the ground are going to be policing authorities: it’s going to be the police, and it’s going to be the military,” says Eghigian. Once the crash site is secure, the next step would probably be forensic work, involving a mix of technicians, scientists, and engineers from within the military branches or from defense contractors.
It’s likely the military’s interest would be threefold: first, to determine whether the flying saucer and its builders pose a threat to humanity, especially the U.S.; second, to try to reverse engineer the technology for military use; and third, to keep anybody else from doing part two. That would almost certainly involve some secrecy — or at least, an attempt at secrecy.
“Militaries keep secrets all the time, and the intelligence community is built around, not just holding secrets, but also exposing secrets for their benefit,” says Eghigian. “If something remarkable happened, I can believe that that would be a dynamic that would emerge.”
But SETI Institute astronomer Seth Shostak questions how long a veil of secrecy would last on a planet surrounded by high-resolution imaging satellites.
“Actual alien craft in our airspace bigger than an office desk would likely be visible to satellites that — among other things — supply imagery to Google Earth,” he writes in a recent essay for the SETI Institute. And it’s not just satellites; more than one country’s military personnel have managed to share sensitive operational information on social media. “I still strongly maintain that alien visitation is not something that could be kept secret. The size of such a secret is just too big,” writes Shostak.
Eghigian is also skeptical that an alien cover-up could last very long, but he says the fact that so many people expect — or already believe in — a government conspiracy to hide aliens from us is, in itself, very revealing.
“So often this stuff about UFOs isn’t about UFOs at all,” Eghigian says. “It gets to the heart of how a person or an organization or group of people, your image and your idea of how government works, and what modern governments are capable of and what they do."
Definitely not actual footage.
DONALD IAIN SMITH/TETRA IMAGES/GETTY IMAGES
WHAT HAPPENS NEXT?
Once the word gets out — and Shostak and Eghigian seem to agree that it almost certainly will, one way or another — scientists around the world would be clamoring for access to the evidence, and even the Department of Defense might have some good reasons to share.
“That would probably be followed by, you would hope, lots of questions coming from journalists like you,” Eghigian says. “And then I think the civilian scientists and researchers, if we catch wind of this stuff, would then be I think clamoring for an opportunity to have a look.”
With nearly 300 research universities in the U.S. alone, not to mention the private sector, there would be a lot of researchers clamoring for dibs on alien autopsies and analyzing the metals in the flying saucer’s hull. Sorting out who should get access to study which pieces of the evidence would quickly become a sticky, and highly politicized, problem.
“One thing I think you can expect absolutely right away is this would turn political,” says Eghigian.
Of course, this story has focused on what would happen if an alien spaceship crashed somewhere in the U.S., but there’s no reason — other than nationalism — to think the U.S. is any more likely to be a UFO crash site than any other country in the world.
“There is a kind of national hubris operating here: If extraterrestrial beings are going to come to Earth, they’re going to visit us!” writes Shostak.

77 Years after the Roswell Incident, What Have We Learned?

77 Years after the Roswell Incident, What Have We Learned?
For many Americans today, the name “Roswell” will inevitably conjure up images of flying saucers crash landing in the remote New Mexico desert; bald, diminutive aliens with gigantic eyes; and bizarre theories about government conspiracies and cover-ups. The events of 75 years ago have spawned books, movies, and TV shows, and the so-called “Roswell Incident” has attained the status of an American myth. To celebrate the 75th anniversary, here is a brief look at some of the many government publications available in Sycamore Library and on the Internet that provide insight into this intriguing story.
THE ROSWELL INCIDENT
In 1947, beginning in the spring and continuing into the fall, a rash of sightings of unidentified flying objects (UFOs) were being reported across the United States, with the maximum number of these sightings occurring during the period from mid-June to early July.
On July 7, 1947, while interest in UFOs was at its height, W.W. “Mac” Brazel appeared at the office of sheriff George Wilcox in Roswell, New Mexico and described the wreckage of a metal disk and some other materials, including tinfoil, broken wood beams, strips of rubber, and thick paper, which he had discovered a few days earlier on the Foster Ranch where he worked, about 75 miles northwest of Roswell. Brazel had heard stories about UFO sightings on the radio recently and wondered if the debris he found might be part of one of those “flying saucers” everyone was talking about.
Sheriff Wilcox contacted Major Jesse A. Marcel, an officer in the Roswell Army Air Field (RAAF) intelligence office, about Brazel’s discovery. Marcel drove to the sheriff’s office to inspect the wreckage, then went out to the ranch with Brazel to collect as much of the debris as they could.
The next day, July 8, the Public Information Office issued a press release, prematurely announcing that the Army Air Force had recovered a “flying disk.” The news media went wild, for this was perhaps the first time the government had ever taken reports of alien aircraft seriously.
Meanwhile, military police were sent to the sheriff’s office to collect the wreckage, which was flown to Eighth Air Force headquarters in Fort Worth (later known as Carswell Air Force Base) for inspection. Officers and staff in Texas determined that the objects were remnants of a weather balloon and its attached metallic radar target.
A few hours after the previous announcement, the RAAF issued a correction, announcing that the debris found at Foster Ranch was from a weather balloon, not a flying saucer. Immediately suspicion was aroused that the government was covering something up.
Years later it turned out there had indeed been a cover-up, but it had nothing to do with aliens or flying saucers from outer space.
FBI REPORT ON ROSWELL
On July 8, 1947, the Dallas Office of the FBI issued a one-page teletype summarizing the Roswell incident. This document relays information from the U.S. Air Force that a hexagonal object appearing to be a “flying disk” had been recovered in the desert near Roswell, New Mexico. The object was described as being attached by cable to a balloon about 20 feet in diameter, resembling a weather balloon. Because of the interest generated by the recent UFO sightings, the disk and balloon were transported to Wright Field in Ohio for examination.
This document is available on the FBI website in their FOIA library known as The Vault. Several more FBI investigations of UFOs conducted from 1947 to 1954 are also included in The Vault.
PROJECT BLUE BOOK
From 1947 to 1969, a total of 12,618 sightings of UFOs were collected and investigated by the U.S. Air Force. The project, known as Project BLUE BOOK, was headquartered at Wright-Patterson Air Force Base in Dayton, Ohio.
As a result of several private and governmental investigations and studies conducted during this time period, the members of the Air Force running Project BLUE BOOK reached the following conclusions:
No UFO reported, investigated, and evaluated by the Air Force had ever given any indication of threat to our national security.
There has been no evidence that sightings categorized as “unidentified” represent technological developments or principles beyond the range of present-day scientific knowledge.
There has been no evidence indicating that sightings categorized as “unidentified” are extraterrestrial vehicles.
On December 17, 1969, the Secretary of the Air Force announced the termination of Project BLUE BOOK. The documentation collected is now in the possession of the U.S. National Archives, and anyone with any further testimony regarding UFOs is referred to one of the many private agencies and individuals that are currently researching such phenomena.
The following blog posts provide more information about records in the National Archives pertaining to UFOs:
In early 1987, British UFOlogist Timothy Good claimed to have been given a highly classified government document indicating that a secret committee of senior U.S. officials called the “Majestic 12” had investigated, and then covered up, the 1947 discovery of a crashed flying saucer containing the bodies of four humanoid aliens.
After this sensational story had been publicized through various news outlets, the Air Force Office of Special Investigations referred the Majestic 12 document to the Dallas FBI to determine whether it was still classified. The Office of Special Investigations announced on November 30, 1988 that the document was “bogus,” and FBI Headquarters instructed Dallas to close the investigation.
GAO REPORT
In February 1994, the General Accounting Office (GAO), acting on the request of Steven H. Schiff, a New Mexico Congressman, initiated an audit to attempt to locate any government records connected with the Roswell incident, and to determine if those records had been properly handled according to established procedures for reporting air accidents.
An extensive search ensued for government records related to the crash near Roswell, and a wide range of classified and unclassified documents dating from July 1947 through the 1950s were examined. These records came from numerous organizations in New Mexico and elsewhere throughout the Department of Defense, as well as from the Federal Bureau of Investigation (FBI), the Central Intelligence Agency (CIA), and the National Security Council.
In 1947, Army regulations required that air accident reports be maintained permanently, and although none of the military services filed a report on the Roswell incident, there was no requirement in 1947 to prepare a report on the weather balloon crash.
Although some of the records concerning Roswell activities had been destroyed, there was no information available regarding when or under what authority the records were destroyed.
Only two government records originating in 1947 have been recovered regarding the Roswell incident:
A 1947 Federal Bureau of Investigations record revealed that the military had reported that an object resembling a high-altitude weather balloon with a radar reflector had been recovered near Roswell.
A 1947 Air Force report noted the recovery of a flying disk that was later determined by military officials to be a radar-tracking balloon.
PROJECT MOGUL: THE REAL COVER-UP
In July 1994, the Office of the Secretary of the Air Force concluded an exhaustive search for records in response to the General Accounting Office (GAO) inquiry about the “Roswell Incident.” After reviewing its records, the Air Force concluded that the debris recovered from the ranch on July 7, 1947, was a weather balloon, but it was not being used strictly for weather purposes. In early 1995 the results of this inquiry were published in a document nearly 1000 pages long, entitled The Roswell Report: Fact vs Fiction in the New Mexico Desert.
An examination of now declassified technical and progress reports revealed that the Air Force had been conducting an experimental, top secret balloon project, called by the code name Project MOGUL, at the nearby Alamogordo Army Airfield (now Holloman AFB) during the summer of 1947. The Air Force admitted in the 1990s that they had been using this project to develop and test a surveillance device designed to fly over nuclear research sites in the Soviet Union and spy on them.
Project MOGUL was a then-sensitive, classified project, whose purpose was to determine the state of Soviet nuclear weapons research. This was the early Cold War period, and the U.S. government was concerned about the possibility that the Soviets were secretly developing an atomic weapon behind their closed borders. As early as 1945, Dr. Maurice Ewing of Columbia University had proposed to General Carl “Tooey” Spaatz (supervisor of the bombing of Nagasaki and Hiroshima) that a connected string of high-altitude balloons equipped with microphones could be sent floating over the Soviet Union to pick up sound waves and monitor any attempts by the Soviet government to test their own atomic weapon.
The weather-balloon story put out in 1947 had actually been a cover for this top secret spy operation, but only after the documents had been declassified in the post-Cold War era could the true cover-up finally be revealed.
CASE CLOSED
The 1995 Roswell Report dealt only with the material recovered from the first reported incident near Roswell, which had occurred in 1947.
In the decades after the Roswell Incident there were many more reports of UFOs, including two more that occurred near Roswell. Some of these new reports mentioned alien bodies that had been discovered among the crash debris. These bodies were not a part of the original reports of 1947, so they were not discussed beyond a brief mention in the Air Force’s report, but at some point dim memories and inaccurate retellings had caused the various reports to become mixed up and conflated, so that the original 1947 incident was associated not just with the idea of a flying saucer landing in the desert, but also with rumors of dead aliens and more government cover-ups. In 1995 there was even a film released of an alleged “alien autopsy” that took place in connection with the 1947 crash.
In order to respond to these later allegations, the Air Force published a 1997 update to their 1995 report. The update was confidently titled The Roswell Incident: Case Closed. Together, these two reports provide the definitive U.S. Army statement on what really happened during the Roswell incident.
In the final report, which celebrates its 25th anniversary this year, Air Force researchers investigated reports of alien bodies, and concluded that in every case there was a logical explanation much more mundane than treating them as evidence of the misadventures of extraterrestrial visitors. In almost every case, the fantastic stories collected by UFO theorists and enthusiasts proved to be misinterpretations—intentional or inadvertent—of actual operations and tests carried out by the U.S. Air Force in the 1950s. In some cases, the “alien” bodies were in reality anthropometric test dummies, sometimes damaged, used in scientific experiments involving high altitude balloons. In other cases, there were real bodies, but they were human Air Force personnel who had been injured or killed in the line of duty, not creatures from outer space.
In the public eye and in the popular media, UFOs have come to be associated primarily with “flying saucers” and other visits from extraterrestrial beings. For the armed forces and other government agencies, an unidentified flying object (now more likely to be referred to as “unidentified aerial phenomenon,” or UAP) is thought of as a matter of national security, and is more likely to be an airplane, drone, or other espionage device controlled by a member of an enemy government on Earth. This may not be as sensational as a visit from outer space, but it may be closer to the truth.

Unveiling the Mysteries: Top Secret Alien Crashes and Cover-Ups
Unveiling the Mysteries: Top Secret Alien Crashes and Cover-Ups
The phenomenon of unidentified flying objects (UFOs) and their alleged crashes have long intrigued both the public and researchers. Several key incidents, often shrouded in secrecy, have fueled speculation about extraterrestrial life and government cover-ups. This article explores some of the most notable undercover alien crashes reported over the years, drawing on testimonies and investigations that continue to captivate the imagination.
1. The Rendlesham Forest Incident (1980)
One of the most compelling UFO encounters occurred in Rendlesham Forest, near a US Air Force base in Suffolk, England. On December 26, 1980, Airman John Burroughs and Sergeant James Penniston were dispatched to investigate strange lights reported in the forest. What they found defied explanation.
As they approached the lights, Penniston reported seeing a triangular craft with bizarre, hieroglyphic-like inscriptions. Upon touching the craft, he experienced a sudden influx of binary code, which he felt compelled to write down the next day. Decoded years later, this binary message suggested a mission of “exploration of humanity” and hinted at an origin year of 8100, leading some to speculate about time travel rather than extraterrestrial visitation.
Both Burroughs and Penniston experienced lasting health effects, possibly from radiation exposure. The incident, initially investigated briefly by the US military, was allegedly kept away from the public eye, adding to its mystery and allure.
2. The Berwyn Mountains Incident (1974)
Another significant event took place in Llandrillo, Wales, on January 23, 1974. The quiet rural village was shaken by an enormous explosion, accompanied by a bright light falling from the sky. Huw Lloyd, then 14, witnessed the aftermath, describing an intense glow on the mountainside.
Ancient astronaut theorists propose that the explosion was caused by the crash of an extraterrestrial spacecraft. Despite alternative explanations, such as an earthquake, the distinct characteristics of the event—particularly the intense light—make it a compelling case for a UFO encounter.
3. The Kingman Incident (1953)
In 1953, following a nuclear test under the code name Upshot-Knothole, a disc-shaped object was seen descending rapidly from the sky near Kingman, Arizona. Scientists and engineers were covertly assembled to investigate the crash site, where they discovered a 40-foot diameter craft and four extraterrestrial beings.
The craft and its occupants were transported to Groom Lake, Nevada, now known as Area 51. According to accounts, one of the beings, referred to as “J-Rod,” survived and collaborated with the US government to reverse-engineer alien technology. Testimonies from individuals like Navy pilot Bill Uhouse and microbiologist Dan Burish describe direct interactions with J-Rod, who was housed in a special underground chamber.
4. The Roswell Incident (1947)
Perhaps the most famous of all UFO incidents, the Roswell crash, occurred in July 1947. Initial reports claimed the recovery of a flying saucer by the military, but the story was quickly changed to a weather balloon explanation. This sudden retraction has led to widespread belief in a cover-up.
Witnesses reported seeing strange debris and alien bodies at the crash site. Over the years, numerous leaked documents and testimonies have emerged, suggesting that the US government recovered extraterrestrial technology and beings, storing them at military installations. The hangar at Walker Air Force Base in Roswell, where the wreckage was allegedly first taken, remains a focal point for researchers and enthusiasts.
These undercover alien crashes, marked by credible witnesses and compelling evidence, continue to spark debate and curiosity. The involvement of military personnel and the detailed descriptions of the encounters lend credence to these accounts, while the recurring themes of government secrecy and advanced technology underscore the potential significance of these events. Whether viewed as extraterrestrial encounters or advanced time travel experiments, these incidents challenge our understanding of the universe and our place within it.
The Ukrainian military recorded the flight of a disk-shaped UFO hovering over the front line.
This is reported by the Daily Mail and publishes the video.
The UFO was spotted by soldiers of the 406th brigade using a Mavic drone. Their drone was more than 150 meters above sea level.
“What can they shoot at us with? Holy shit,” ‘What the hell is that?’, ‘UFO whatever,’ military officials are discussing behind the scenes whether to attack the object.
It is reported that the unknown object could be the size of a large ship and is more than 50 kilometers away.

The thermal imager showed that the UFO was warmer than its surroundings, but the technology produced a red error message that prevented us from understanding more about the object.
It is noted that this flying object bore a striking resemblance to a thin cylindrical object spotted over Iraq in May 2022 by the infrared “thermal” camera of the US Air Force’s Reaper drone.
Experts believe this could also be a case of the mirage phenomenon known as “Fata Morgana.”
This mirage occurs when a top layer of warm air and a bottom layer of cold air create an “atmospheric channel” that refracts or bends light, creating reflections in the air.
Ruimteschip van Boeing, met 2 astronauten, veilig aangekomen bij ruimtestation ISS (maar niet zonder problemen)
Ruimteschip van Boeing, met 2 astronauten, veilig aangekomen bij ruimtestation ISS (maar niet zonder problemen)
Artikel door Wim De Maeseneer
Met meer dan een uur vertraging is vanavond rond half 8 de Starliner aangekomen bij het ruimtestation ISS. Even was het spannend, toen op 400 kilometer hoogte bleek dat er iets mis was met 5 van de 28 stuwmotoren van het ruimteschip.
De koppeling met het ISS moest wachten en de 2 astronauten, Butch Wilmore (61) en Suni Williams (58) moesten van automatische naar handmatige piloot overschakelen. Ze moesten op een veilige afstand achter het ruimtestation blijven vliegen, dat met 28.000 kilometer per uur rond de aarde vliegt.
Even later kwam het nieuws dat het team aan de grond een oplossing had gevonden om 4 motoren weer aan de praat te krijgen. Starliner mocht aan het ISS koppelen en om 19.34 uur klonken de verlossende woorden vanuit mission control: "Butch en Suni, mooi gedaan."
Nog eens 2 uur later, na een hele reeks procedures, mochten Wilmore en Williams eindelijk het luik van hun ruimteschip openen en het ISS betreden. Daar werden ze hartelijk verwelkomd en geknuffeld door de bemanning van het ruimtestation. Dat zijn momenteel 4 Amerikaanse en 3 Russische astronauten. Suni Williams kon zelfs een vreugdedansje in gewichtloosheid niet bedwingen.
Naast de 2 astronauten heeft Starliner ook nog 340 kilogram vracht mee naar het ISS gevoerd. En daar zit 1 heel opvallend wisselstuk tussen: een nieuwe urinepomp. Die moet het defecte exemplaar vervangen, om zo weer drinkwater van urine te kunnen maken aan boord.
2 nieuwe gaslekken gevonden in Starliner
Starliner werd gisteren voor de eerste keer gelanceerd met astronauten aan boord. Het is de eerste bemande testvlucht van het ruimteschip van lucht- en ruimtevaartbedrijf Boeing. Het hele project heeft jaren vertraging opgelopen door technische problemen. Ook de lancering moest verschillende keren worden afgeblazen.
Voor de lancering werd al een heliumlek gevonden in het ruimteschip, maar NASA en Boeing oordeelden dat het veilig genoeg was om ondanks het lek toch te lanceren. Vandaag werden nog 2 nieuwe lekken ontdekt in Starliner. Maar opnieuw werden de lekken niet beschouwd als ernstig genoeg om de missie of bemanning in gevaar te brengen.
De 2 astronauten blijven nu ongeveer een week in het ISS. Daarna keren ze met Starliner terug om hangend aan parachutes weer op de aarde te landen. Pas dan zullen we weten of Starliner klaar is om vanaf 2025 vaker astronauten en vracht naar het ISS te voeren en terug te brengen.
Het ruimtevaartuig Starship is bij de vierde testvlucht voor het eerst succesvol teruggekeerd naar de aarde. Fabrikant SpaceX meldt op X, het voormalige Twitter, dat het ruimtevaartuig is neergekomen in de Indische Oceaan.
The European Space Agency has retired its Ariane 5 rocket, and all eyes are on its next generation, Ariane 6. The rocket’s pieces have been arriving at the Kourou facility in French Guiana and are now assembled. ESA has now announced they’ll attempt a test launch on July 9th and hope to complete a second flight before the end of 2024. This new heavy-life rocket has a re-ignitable upper stage, allowing it to launch multiple payloads into different orbits.
“Ariane 6 marks a new era of autonomous, versatile European space travel,” said ESA Director General Josef Aschbacher, who announced the launch data at the Innovation and Leadership in Aerospace (ILA) Berlin Air Show on June 5, 2024. “This powerful rocket is the culmination of many years of dedication and ingenuity from thousands across Europe and, as it launches, it will re-establish Europe’s independent access to space. … I would like to thank the teams on the ground for their tireless hard work, teamwork and dedication in this last stretch of the inaugural launch campaign. Ariane 6 is Europe’s rocket for the needs of today, adaptable to our future ambitions.”

Ariane 6 has been in the works since the early 2010s to be a replacement the workhorse Ariane 5, which is no longer in production. Ariane 5’s first successful launch was in 1998, and since then has sent 109 spacecraft on their way, including the first ATV Jules Verne to the International Space Station and the James Webb Space Telescope to the second LaGrange point 1.5 million km (1 million miles) from Earth.
Ariane 6 is an expendable launch vehicle – not reusable like SpaceX’s rockets — that comes in two versions, with a modular design that can be customized: the rocket can use either two or four P120C strap-on boosters, depending on mission requirements. With the various designs, it can put a 4,500 kg payload into a geostationary transfer orbit or 10,300kg into low Earth orbit using the two boosters, and with four side boosters, it can launch 11,500 kg into a geostationary transfer orbit and 20,600kg into low Earth orbit. The re-ignitable upper stage allows for multiple satellites to launch on a single flight.

Ariane 6 was developed at a cost of just under 4 billion euros ($3.9 billion) and was originally planned for its first launch in July 2020. However, the project has been hampered by several delays, including work-related issues during the Covid-19 pandemic.
“The announcement of the scheduled date for Ariane 6’s first flight puts us on the home stretch of the launch campaign and we are fully engaged in completing the very last steps,” said Martin Sion, CEO of ArianeGroup, the prime contractor of the Arian 6. “This flight will mark the culmination of years of development and testing by the teams at ArianeGroup and its partners across Europe. It will pave the way for commercial operations and a significant ramp-up over the next two years. Ariane 6 is a powerful, versatile and scalable launcher that will ensure Europe’s autonomous access to space.”

At the Spaceport in French Guiana, various payloads have been integrated on Ariane 6’s payload carrier. One major milestone must be met before launch: a full wet dress rehearsal, which is having a fully fueled vehicle going through all the steps of a countdown, but not the actual ignition of the rocket engines. Once this activity has been completed, the Ariane 6 Task Force will provide an update, confirming the date for the inaugural flight.
Success! SpaceX’s Starship Makes a Splash in Fourth Flight Test
SpaceX’s Starship earned high marks today in its fourth uncrewed flight test, making significant progress in the development of a launch system that’s tasked with putting NASA astronauts on the moon by as early as 2026.
The Super Heavy booster blasted off from SpaceX’s Starbase complex in South Texas at 7:50 a.m. CT (12:50 p.m. UTC), rising into the sky with 32 of its 33 methane-fueled Raptor engines blazing. Super Heavy is considered the world’s most powerful launch vehicle, with 16.7 million pounds of thrust at liftoff.
Minutes after launch, the rocket’s upper stage — known as the Ship — separated from the first stage, firing up its own set of six Raptor engines. Meanwhile, Super Heavy flew itself to a controlled splashdown in the Gulf of Mexic
The soft splashdown marked a new achievement for Starship. During the third flight test, which took place in March, only a few of Super Heavy’s engines were able to light up again for a crucial landing burn. As a result, the booster hit the water with an uncontrolled splat.
Eventually, SpaceX plans to have the Super Heavy booster fly itself back to its base after doing its job.
The upper stage reached orbital-scale altitudes in excess of 200 kilometers (125 miles), but completing a full orbit wasn’t part of today’s plan. Instead, SpaceX aimed to have Ship make its own soft splashdown in the Indian Ocean.
Streaming video, relayed via SpaceX’s Starlink satellite network, showed the rocket’s protective skin glowing with the heat of atmospheric re-entry. Burning debris broke off from one of Ship’s control fins, damaging the camera’s lens — but the fuzzy view nevertheless confirmed that the spacecraft successfully hit the mark. That represented another advance over the third test, when the Ship broke up during its descent to the ocean.
“Despite loss of many tiles and a damaged flap, Starship made it all the way to a soft landing in the ocean!” SpaceX founder Elon Musk exulted in a posting to his X social-media platform.
NASA Administrator Bill Nelson added his congratulations on X, and noted that the successful test was a plus for the space agency’s Artemis moon program. “We are another step closer to returning humanity to the moon through Artemis — then looking onward to Mars,” he wrote.
A customized version of Ship is slated to serve as the lunar lander for Artemis 3, which would mark the first crewed mission to the moon’s surface since Apollo 17 in 1972. That mission is currently scheduled for 2026, but the timing depends in part on when the Starship system will be ready.
SpaceX’s uncrewed flight tests are following a step-by-step path to get Starship in shape for a wide variety of missions — including the deployment of hundreds of Starlink satellites, point-to-point travel between spaceports on Earth, and crewed odysseys to the moon, Mars and beyond.
Starship rockets aren’t carrying payloads for these early tests. “We said it before, we’re going to say it 9,000 times: The data is the payload,” SpaceX commentator Dan Huot said during today’s flight test.
But as the development program proceeds, the envelope for the flight tests will be widened to include multi-orbit operations, payload deployments and precision touchdowns on landing pads. Before today’s test, SpaceX and the Federal Aviation Administration worked out an arrangement that’s expected to streamline the regulatory process for future flights.
After the Pentagon‘s great UFO declassification and congressional hearings, NASA decided to hunt down the aliens. The agency possesses advanced technology on Planet Earth, exploring the possibility of transforming satellites into alien seekers to probe unexplained sightings without launching new equipment. The Galileo Project is designing a space mission to rendezvous with the next anomalous (Oumuamua-like) interstellar object that zooms into our solar system.
Is that the first time NASA became interested in alien civilizations? NASA whistleblowers, who claimed to have closely worked in some of the top missions, do not think so. Former NASA employee, Donna Hare reportedly saw a photo of a distinct UFO. Her colleague explained that it was his job to airbrush such evidence of UFOs out of photographs before they were released to the public.
On May 9, 2001, over twenty military, intelligence, government, corporate and scientific witnesses came forward at the National Press Club in Washington, DC to establish the reality of UFOs or extraterrestrial vehicles, extraterrestrial life forms, and the resulting advanced energy and propulsion technologies. As part of the Disclosure Project, Donna Hare, a photographic scientist testified to have worked for NASA contactor Philco Ford in the early 1970s. She had a high-security clearance to walk in NASA’s photo lab and other departments.
During the Disclosure Project press conference, Hare revealed that NASA covered up and eliminated space anomalies such as UFOs from the satellite photos. Hare has got several awards in the space programs. She dedicated most of her time as a technical illustrator to space programs. She created lunar maps and landing slides and had been working for 15 years as a sub-contractor for NASA.

Hare claimed to have had access to a place known as “Building Eight,” from where she made contacts with high-ranking officials. Once, she walked into a restricted area which was NASA’s photo lab. She noticed the lab had photographs of the Moon taken from satellites. She was with a friend who pointed at one of the photographs and surprisingly, she saw a round white dot.
“Good morning everyone! My name is Donna Hare, and I worked at Philco Ford aerospace from 1967 to 1981. During that time, I was a design illustrator draftsman. I did the launch slides, landing slides, and also projected plotting boards lunar maps for NASA. We were a contractor but most of the time, I worked in Building 8. I had the opportunity to do extra work during downtime which was between missions, and I walked into a photo lab which was the NASA lab across the hallway. I had a secret clearance which is not that high but I was able to go into restricted areas.
At the time, I was talking to one of the techs in there and he drew my attention to a NASA photograph. It had a “Dot” on it, and I asked what it was. Well, he drew my attention to it and I said is that a dot on the emulsion? He was smiling and he had his hands crossed… This was an aerial photograph of the Earth, I’m assuming the Earth because it had pine trees on it and the shadows of the craft or whatever it was were at the same angle as the trees and by its very nature, a UFO. And I wanted to clarify that to the gentleman that was talking to me… So, I did not know what this was but I realized at this point that it’s very secret.
I asked him what he was gonna do with this piece of information. He said they always airbrush these out before they sell them to the public, so they’re pissed pesky little creatures appearing on this photograph they wanted to get rid of. After that, I decided I would ask questions to other people that worked there (away from the site and not on site).
A guard told me that he was asked to burn some photographs and not to look at them, and there was another guard guarding him who was in green fatigues watching him burn the photographs and he said he was too tempted he looked at one.
I knew someone in quarantine with the Apollo astronauts he told me that the Apollo astronauts saw crap on the moon when we landed. He said that the astronauts are told to keep this quiet.”
Hare was told by one of the sources that during one of the moon landings, three UFOs had landed. Subsequently, there was a codeword “Santa Claus” for these crafts. She said she would be willing to testify before Congress. (Source)
In 2000, Gary McKinnon, a British Hacker who got so fed up with the government hiding information related to UFOs and free energy that he decided to hack the most secured servers of NASA and the Pentagon. McKinnon said that he had seen real photographs of UFOs in computer files at the Johnson Space Center Building. He even took a screenshot of one of the cigar-shaped UFOs in-between space and the earth’s atmosphere. Unfortunately, it was removed from his computer after being seized.
Below is the recreation of the famous ‘NOT MAN MADE’ craft that was seen by McKinnon when he hacked & accessed NASA computers. (Source)

Scientists have made an unexpected discovery on Greenland’s far northernArctic ice sheet.
As the frozen environment awakens in the spring after the months it spends blanketed in darkness each year, signs of life begin to return to Greenland’s icy landscape. Several large animals, including the region’s polar bears, arctic terns, and musk oxen, begin to stir as sunlight warms the frozen Earth.
Now, scientists have learned that those aren’t the only massive lifeforms that dwell on Greenland’s ice, although new research is revealing how others have remained undiscovered for so long.
GREENLAND’S INVISIBLE “GIANTS”
Researchers studying Greenland’s icy ecosystem report the new discovery of gigantic viruses thriving on the region’s Arctic ice. These viruses could help manage local algal blooms and may even reduce the speed at which ice melts.
Lying dormant on the ice during the months, Greenland remains in darkness. As spring arrives, algae begin to bloom, causing large darkened areas on the ice sheet. This reduces the sunlight it reflects and induces faster melting, a process that could contribute to global warming.
Laura Perini, a postdoctoral researcher from the Department of Environmental Science at Aarhus University, says the giant viruses she and her colleagues have discovered living alongside these Arctic algae may be acting as a natural control mechanism that helps to curb their blooms.
“We don’t know a lot about the viruses, but I think they could be useful in alleviating ice melting caused by algal blooms,” Perini said in a statement. “How specific they are and how efficient it would be, we do not know yet. But by exploring them further, we hope to answer some of those questions.”
At as little as 20 nanometers in size, viruses are generally much smaller than bacteria. However, the viruses Perini and her colleagues have discovered in Greenland are massive by comparison, capable of growing to sizes as much as 2.5 micrometers, making these “giant” viruses larger than most bacteria.
These invisible giants lurking on Greenland’s ice sheet aren’t the only unusually large viruses known to scientists. In 1981, similar massive viruses were discovered in oceanic environments. Like their icy cousins, these giant viruses also infected green ocean algae. Additional examples have also been found on land, and even a few varieties are known to dwell in our bodies.
Still, Perini and her team’s discovery marks the first time that giant viruses have been found thriving on surface ice, subsisting off of microalgae dwelling in snow. These curious organisms were found in dark ice, as well as samples of red snow that the team analyzed.
The new findings challenge past notions that the Arctic landscape was barren and devoid of life. Scientists today recognize it as an ecosystem where bacteria, filamentous fungi, yeasts, protists, and giant viruses thrive and interact.
“There’s a whole ecosystem surrounding the algae. Besides bacteria, filamentous fungi and yeasts, there are protists eating the algae, different species of fungi parasitizing them, and the giant viruses that we found, infecting them,” Perini says.
re massive in comparison to other viruses, these newly discovered arctic “giants” are still invisible to the naked eye. They might have gone unnoticed if Perini had not discovered them while analyzing DNA in the samples her team collected, where sequences similar to other known giant viruses were observed.
Although they aBy extracting and sequencing mRNA from their samples, Perini and her team confirmed that viruses were present and living on the ice.
Unlike normal viruses, giant viruses can transcribe their DNA into mRNA themselves, whereas smaller varieties have to rely on hijacking the cells of their hosts. Many questions remain about these unusually large viruses, including what ecological roles they play and about their specific hosts.
Further studies are expected to reveal how these giant viruses interact in their Arctic ecosystem, and in the months ahead, Perini and her team plan to publish additional research on how these viruses infect microalgae, which could help to reveal new insights into the curious, “invisible” giants that thrive on the Greenland Ice Sheet.
Perini and her team’s paper, “Giant viral signatures on the Greenland ice sheet,” was published in the journal Microbiome in May.
Unveiling the US Government’s Secret Alien Interrogation Program: Jon Stewart’s Investigation
Unveiling the US Government’s Secret Alien Interrogation Program: Jon Stewart’s Investigation
The idea of the U.S. government engaging in secretive programs involving extraterrestrial beings has long been a staple of conspiracy theories and speculative fiction. However, Jon Stewart, a former professional wrestler turned investigative journalist and political figure, claims to have uncovered evidence supporting the existence of such a program. Stewart’s meticulous investigation over two decades centers around an alleged interrogation of a Gray Alien captured on VHS tape from the early 1990s.
The Discovery and Investigation
In 1997, Jon Stewart stumbled upon a documentary featuring purported footage of an alien interrogation. This documentary, featuring a tan-colored Gray Alien experiencing apparent respiratory distress, captivated Stewart’s interest. Unlike typical Hollywood productions, the footage seemed unremarkable in its presentation, adding to its perceived authenticity. Intrigued by the casual nature of the video, Stewart sought expert opinions from video and animation professionals, all of whom failed to identify any signs of tampering or forgery.
Stewart’s quest for validation led him to consult with medical and military personnel allegedly involved in the interrogation. These interviews unveiled a narrative deeply intertwined with the clandestine activities of a faction within the military establishment, purportedly linked to the secretive S-4 facility within Area 51. The culmination of Stewart’s investigation led him to assert the authenticity of the leaked tape, believed to have been disseminated by an insider known as Victor.
The Whistleblower: Victor
Victor, a biologist employed by the Defense Intelligence Agency (DIA), played a central role in Stewart’s investigation. Victor’s responsibilities included managing the alien interrogation and retention program at S-2 Alpha, a facility south of Area 51. According to Stewart, Victor was the caretaker of six deceased Eban beings stored in glass tubes filled with liquid. His duties also involved educating dignitaries, military personnel, and scientists about the extraterrestrials and their preservation.
Victor’s revelations extended beyond his role at S-2 Alpha. He claimed to have interacted with high-profile figures such as Dick Cheney and Donald Rumsfeld, discussing the deceased aliens. Despite his efforts to bring this information to light, Victor expressed frustration in a 2008 documentary about the lack of interest from the ufology community in verifying his claims or the existence of S-4.
The Alien Interrogation Footage
The footage that sparked Stewart’s investigation depicted an alien being interrogated by intelligence officers through telepathic means. Medical personnel attended to the alien, which appeared to be in distress. The video included a digital overlay with the initials “DNI SL-27,” suggesting the involvement of the Department of Naval Intelligence (DNI). This department, although officially non-existent, was mentioned by a U.S. senator in a manner that reinforced the video’s credibility for Stewart.
The alien, described as a hybrid of organic and synthetic material, exhibited unique physical characteristics such as round eyes and a tan complexion, deviating from the typical portrayal of Gray Aliens. The being’s movements, described as mechanical and puppet-like, further fueled the authenticity claims, as these characteristics aligned with descriptions from other alleged encounters with Gray Aliens.
Speculations and Theories
Throughout his investigation, Stewart encountered various theories regarding the nature and origin of these extraterrestrial beings. One prevalent theory suggests that these aliens are interdimensional travelers capable of traversing space and time by bending the fabric of the universe. Others believe that the Grays are synthetic entities created by other extraterrestrial races to serve as scouts or explorers.
The motivations behind the alleged alien presence on Earth remain a topic of debate. While some experts speculate that these beings have benevolent intentions, others suggest a more ominous perspective, viewing them as demonic entities with a hidden agenda. This dichotomy of beliefs reflects the broader uncertainty and fear surrounding the extraterrestrial phenomenon.
The Government’s Stance and Implications
Stewart’s investigation raises critical questions about the U.S. government’s knowledge and involvement in extraterrestrial activities. The reluctance to disclose information and the alleged use of advanced alien technology to maintain global dominance suggest a complex web of secrecy. According to Stewart, the government’s monopoly on alien technology provides a strategic advantage, making the U.S. military 15 to 20 years more advanced than its global counterparts.
The potential benefits of alien technology extend beyond military applications. Innovations such as zero-point energy and advanced medical treatments could revolutionize various sectors, from energy to healthcare. However, the fear of losing control over these technologies and the societal upheaval they might cause has likely contributed to the continued secrecy.
Jon Stewart’s investigation into the U.S. government’s alleged alien interrogation program presents a compelling narrative that challenges conventional understanding. While the authenticity of the footage and the existence of such a program remain subjects of debate, Stewart’s findings underscore the need for greater transparency and openness in discussing extraterrestrial phenomena. As the quest for truth continues, the hope remains that one day, humanity will have a clearer understanding of its place in the cosmos and the potential interactions with otherworldly beings.
When Boeing Starliner launched at 10:52 a.m. Eastern on Wednesday from Space Launch Complex 41 at Cape Canaveral Space Force Station, so began the critical first chapter of the company’s Crew Flight Test.
Astronauts Butch Wilmore and Suni Williams flew at 17,500 miles per hour northbound along the U.S. East Coast, towards Ireland, and over the Mediterranean Sea before entering orbit around Earth.
If Starliner aces the checks, docking with the International Space Station, reentry and landing in this next week, it will become the second U.S. human-rated spacecraft capable of ferrying astronauts into orbit.

NASA astronauts Butch Wilmore and Suni Williams bid farewell to a crowd, which included their family and friends, by giving away flowers and tossing out mission patches. Astronaut Doug Wheelock (not pictured) was also in the crowd, taking video and photos for their families to remember the moment. Soon after, Wilmore and Williams boarded a van to reach the Boeing Starliner “Calypso” spacecraft for the Crew Flight Test launch.

“Suni and I are honored to share this dream of spaceflight with each and every one of you,” Wilmore said from inside the Starliner, five minutes before launch.
“Let’s go Calypso! Take us to space, and back!” Williams said.

Williams and Wilmore will dock with the forward port of the ISS Harmony module at 12:15 a.m. Eastern time, with a hatch opening around 2:00 p.m. Eastern, according to NASA.
GREGG NEWTON/AFP/GETTY IMAGES The next step is certification. Williams and Wilmore will conduct a series of manual tests, and evaluate the performance of Starliner all the way through landing in the U.S. southwest in about one week.
Once Starliner is certified, NASA will have dissimilar redundancy in space, two different options to launch and return astronauts to and from humanity’s farthest human outpost.
I have always wanted a 3D printer but never quite found a good enough reason to get one. Seeing that NASA are now 3D printing metal is even more tantalising than a plastic 3D printer. However, thinking about it, surely it is just a computer controlled soldering iron! I’m sure it’s far more advanced than that! Turns out that the first print really wasn’t much to right home about, just an s-curve deposited onto a metal plate! It does however prove and demonstrate the principle that a laser can liquify stainless steel and then deposit it precisely in a weightless environment.
“This S-curve is a test line, successfully concluding the commissioning of our Metal 3D Printer,”
Arguably 3D printers have revolutionised manufacturing and prototyping industry. The invention of them has been attributed to Chuck Hull who in 1983 but it’s more true to say he laid the foundations. Hull developed a technique known as stereolithography which involved creating 3D objects by curing thin layers of a photopolymer with UV light. The 3D printers that are commercially available came 5 years later in 1988.
NASA and ESA have been interested in 3D printing in space to make repair/improvement engineering far cheaper, sustainable and timely. Instead of waiting for parts to be shipped up to the ISS. To that end there has been a more conventional plastic 3D printer on board the ISS since 2014 because a 3D printed replacement is far simpler and more cost effective. Indeed ESA are trying to create a circular space economy to recycle materials already in orbit. It makes far more sense to repurpose existing materials in orbit – such as metal from old satellites – to make new tools or parts removing the need for rocket launches to transport them.

The metal printer that is now on board the International Space Station employs stainless steel wire being fed onto the medium being printed upon. A high power laser which is a million times more powerful than a laser pointer then heats it up melting a small section. As the steel wire feeds into the melt pool it melts, adding to the metal, making it slightly raised.
Unlike a 3D printer you may have (or I may be trying to justify) which you can control from your own computer, the printer on ISS is controlled entirely from the ground. The crew do have tasks however, they have to open a nitrogen and venting valve before the printing can start. I guess it’s almost the equivalent of putting the paper in your printer at home!
The printer was developed by a team led by Airbus under the ESA Directorate of the Human and Robotic Exploration contract. It arrived on the ISS in January 2024 where the 180kg printer was installed in the ESA Columbus Module.

The next step for the printer is to print four shapes that have been chosen for full-scale 3D printing. They will then be returned to Earth for analysis and comparison against reference prints already created in normal gravity. The teams hope to explore how microgravity impacts 3D printing. Two of the 3D printed parts will go to the Materials and Electrical Components Lab at ESTEC in Netherlands. The other two will go to the European Astronaut Centre at the Technical University of Denmark.
Researchers at Harvard and Google have produced the most detailed map of the human brain ever rendered, revealing the complicated neural interactions occurring within a tiny cubic millimeter sample of brain tissue.
The collaborative effort showcases the power of current electron microscopy paired with the ever-growing capabilities of artificial intelligence, and offers unique insights into neural connections in vivid imagery made available online by the researchers.
Within a single cubic millimeter of brain tissue are close to 57,000 cells, along with hundreds of synapses and blood vessels that, when reproduced in the Harvard and Google collaboration’s reconstructions, resulted in close to 1,400 terabytes of data.
The groundbreaking effort was led by Jeff Lichtman, Harvard’s Jeremy R. Knowles Professor of Molecular and Cellular Biology and newly appointed dean of science, offering an unprecedented glimpse at the intricacies of the human brain and its inner workings.

A decade in the making, Lichtman and the Google team’s research combines electron microscopy with Google’s advanced AI in a meticulous reconstruction of the complexities of the brain, as outlined in a recent scientific study by Lichtman, along with former Harvard postdoctoral researcher Alexander Shapson-Coe, Michał Januszewski of Google Research, and Harvard postdoctoral researcher Daniel Berger as co-first authors.
Now, the newly unveiled brain map, which the researchers call a “connectome,” has revealed what Lichtman recently characterized as “an alien world inside your own head.”
In the newly published study, the authors say the functions occurring within our brains represent the key difference that separates us from other life on Earth. Despite this recognition, we currently possess a less-than-complete understanding of the intricate synaptic circuitry underlying these functions.
Enter Google Research’s Connectomics team, which, over the last decade, has worked toward using machine learning to construct a clearer picture of the human brain at previously unmatched scales. The result of this work allows researchers to produce visualizations of extremely large volumes of neural circuits at high resolutions, which could lead to entirely new discoveries about the way our brains function.
A limiting factor in this research involves the problems with obtaining high-quality samples of human brain tissue. Unlike other organ biopsies, brain biopsies rarely occur except when used to extract neoplastic masses, which aren’t ideal for creating visualizations of normal brain structure. In past attempts, brain organoids composed of human cells have been used, but since they lack cortical layers, they were unable to faithfully reproduce all of the features of real human brain tissue.
In their recent paper, the study’s authors proposed a new strategy involving the use of human brain tissue extracted during neurosurgical procedures, which they said “could be leveraged to study normal—and ultimately disordered—human neural circuits.”
Above: Lichtman and the research team report that on some occasions, a single axon, shown in blue, was found to make repeated synaptic connections, indicated by yellow areas in the image above, with a target neuron (shown in green). Presently, the researchers say the purpose of these tight connections is unknown. Credit: Google Research & Lichtman Lab (Harvard University). Renderings by D. Berger (Harvard University).
Lichtman obtained such a sample a decade ago. Smaller than a single grain of rice, the sample had been retrieved from the brain of a patient with severe epilepsy as part of a standard procedure where a small portion is removed to help reduce seizures and then analyzed to determine whether it is normal. Apart from the patient’s age and gender, Lichtman knew nothing else about the sample’s origins.
In their research, the team used electron microscopy to produce a massive set of very detailed images using this small piece of temporal cortex, which was only about 1 cubic millimeter in size. Then they analyzed the data with Google’s powerful AI, reconstructing thousands of neurons, over a hundred million synaptic connections, and other brain components like glial cells, blood vessels, and myelin.
The tremendous resulting trove of data, which revealed a previously unrecognized class of neurons hidden within deep layers of the tissue and “very powerful and rare multisynaptic connections between neurons throughout the sample,” was made available online, along with tools to aid other researchers in analyzing it.

“This work provides evidence of the feasibility of human connectomic approaches to visualize and ultimately gain insight into the physical underpinnings of normal and disordered human brain function,” the researchers write in their new study. “It is hoped that this endeavor will be aided by providing free access to all of the data and relevant tools.”
“Given the enormous investment put into this project, it was important to present the results in a way that anybody else can now go and benefit from them,” said Google Research collaborator Viren Jain of the team’s findings.
Supported by the National Institutes of Health BRAIN Initiative, this collaboration’s ultimate goal is to create a high-resolution map of a whole mouse brain’s neural wiring. This ambitious project will require approximately 1,000 times the data produced from the current 1-cubic-millimeter fragment of human cortex used by Lichtman and his collaborators in the recent research.
The team’s landmark paper, “A petavoxel fragment of human cerebral cortex reconstructed at nanoscale resolution,” was published in the journal Science on May 10, 2024.
Een internationaal team van onderzoekers – waaronder ook wetenschappers van de universiteit van Luik – hebben een nieuwe planeet ontdekt: WASP-193b. En dat is een tamelijk bijzondere planeet; WASP-193b heeft namelijk ongeveer dezelfde dichtheid als een suikerspin.
WASP-193b bevindt zich op zo’n 1200 lichtjaar van de aarde. De planeet is 50 procent groter dan Jupiter, maar heeft een massa die zeven keer kleiner is dan die van Jupiter. Het betekent dat de planeet een zeer geringe dichtheid heeft; vergelijkbaar met de dichtheid van een suikerspin, zo stellen de onderzoekers.
Afwijking
WASP-193b gaat voor nu de boeken in als de op één na minst compacte planeet die tot op heden is ontdekt; alleen de eerder gespotte – maar wel veel kleinere – Kepler-51d heeft een nog lagere dichtheid. “De extreem lage dichtheid (van WASP-193b, red.) is wat de planeet echt doet afwijken van de meer dan 5000 andere exoplaneten die tot op heden zijn ontdekt,” vertelt onderzoeker Khalid Barkaoui.
Barkaoui en collega’s vingen een eerste glimp op van WASP-193b dankzij de zogenoemde Wide Angle Search for Planets (kortweg WASP). Binnen dit onderzoeksproject wordt met behulp van een observatorium op het noordelijk halfrond en een observatorium op het zuidelijk halfrond de helderheid van duizenden sterren in de gaten gehouden. Daarbij werd ook gekeken naar WASP-193: de moederster van WASP-193b. En tussen 2006 en 2008 – maar ook tijdens aanvullende waarnemingen in 2011 en 2012 – zagen onderzoekers de helderheid van deze ster met regelmaat afnemen. Die afnames in helderheid bleken vervolgens te herleiden te zijn naar het bestaan van een planeet die rond WASP-193 cirkelde. Wanneer deze planeet – vanaf de aarde gezien – voor zijn moederster langs beweegt, houdt deze een deel van het licht van zijn moederster tegen, waardoor het lijkt of de helderheid van WASP-193 tijdelijk afneemt.
exoplanet, WASP-193B genoemd, is gevonden op een afstand van 1.232 lichtjaren.
Omlooptijd en omvang
Op basis van de metingen van WASP konden onderzoekers dus al concluderen dat WASP-193 een planeet bezat. Ook wezen de observaties uit dat deze ongeveer 6,25 dagen nodig had om een rondje om zijn moederster te voltooien. Daarnaast konden onderzoekers uit de hoeveelheid zonlicht die WASP-193b tegenhield op het moment dat deze voor zijn moederster langs bewoog ook afleiden hoe groot de planeet ongeveer was: ongeveer 1,5 keer groter dan Jupiter.
Massa
Opmerkelijk werd het echter pas toen de onderzoekers met behulp van andere observatoria ook de massa van de planeet poogden te achterhalen. Tot grote verrassing van de onderzoekers wezen deze aanvullende observaties namelijk uit dat WASP-193b een zeven keer kleinere massa heeft dan Jupiter. En daarmee heeft de planeet – die dus wel 1,5 keer groter is dan Jupiter – een zeer geringe dichtheid. Zo zou WASP-193b een dichtheid hebben van 0,059 gram per kubieke centimeter, zo is in het blad Nature Astronomy te lezen. Ter vergelijking: de dichtheid van Jupiter is 1,33 gram per kubieke centimeter en die van de aarde is maar liefst 5,51 gram per kubieke centimeter.

Suikerspin
“De planeet is zo licht dat het lastig is om een vast materiaal te bedenken (met een vergelijkbare dichtheid, red.),” merkt onderzoeker Julien de Wit op. Toch is het de onderzoekers gelukt; WASP-193b is qua dichtheid nog het beste te vergelijken met een suikerspin. Het bekende snoepgoed kent namelijk een dichtheid van ongeveer 0,05 gram per kubieke centimeter. “De reden dat (WASP-193b, red.) zo vergelijkbaar is met een suikerspin, is dat beiden in feite grotendeels uit lucht bestaan. De planeet is gewoon super fluffy.”
Waar een suikerspin vooral uit suiker bestaat, bestaat WASP-193b voornamelijk uit waterstof en helium, zo vermoeden de onderzoekers. Die gassen lijken een gigantisch omvangrijke atmosfeer te vormen die tienduizenden kilometers verder reikt dan de atmosfeer van Jupiter. Hoe de planeet zo is kunnen opzwellen, is onduidelijk. Wetenschappers hebben verschillende theorieën over hoe planeten ontstaan, maar geen enkele van die bestaande theorieën kunnen het bestaan van WASP-193b vooralsnog verklaren. “We kunnen niet verklaren hoe deze planeet ontstaan is,” bevestigt onderzoeker Francisco Pozuelos. “WASP-193b is een kosmisch mysterie,” voegt Barkaoui toe. De wetenschappers hopen dat toekomstige waarnemingen – met onder meer de James Webb Telescoop – kunnen helpen om dat mysterie op te lossen.
