Eyewitness states: 

Saw a very large cigar shape object hovering floating in the sky over the mountain. Airplane flew towards the object but as it got closer the airplane disappeared because of the distance but the cigar shape was huge so I could easily see it.

AI Focused Black Knight Satellites, Up Close And Personal, UFO UAP Sighting News.

Hey all, I was asked on X and Youtube by many people to put the Dark Knight satellites through the ai program and see what happens. Well I did and it sharpened them a lot and brought the surface of the space craft into focus. It is said that these satellites are tens of thousand of years old or older. That they cannot be approached or they will paralyze the oncoming spacecraft. Tell me your thoughts of what these are and why they are in Earths orbit and why did NASA move the links three times before giving up?

Dat de ontdekking van die extra ogen zo lang op zich heeft laten wachten, is wel te verklaren. Ze zitten – in gefossiliseerde trilobieten – namelijk enigszins verstopt.

Zo’n 500 miljoen jaar geleden wemelden de oceanen van de trilobieten. Dit zijn een bekende klasse uitgestorven geleedpotigen die in vervlogen tijden in de zee leefden. Trilobieten behoren samen met ammonieten en dinosauriërs ongetwijfeld tot de bekendste fossielen. Maar ondanks 150 jaar onderzoek heeft het beestje alsnog verrassingen voor ons in petto. Zo zijn wetenschappers op extra ogen gestuit, die al die tijd over het hoofd zijn gezien.

Ogen

Geleedpotigen hebben meestal twee soorten ogen. Allereerst hebben ze een paar samengestelde ogen (ook wel facetogen genoemd). Deze bestaan vaak uit duizenden aparte lensjes. Daarnaast zijn geleedpotigen ook nog eens uitgerust met mediane ogen. Dit zijn eigenlijk een extra set enkelvoudige ogen, die zich in het midden van het voorhoofd bevinden, tussen de samengestelde ogen in. Alleen trilobieten, een belangrijke groep geleedpotigen die ten tijde van het Paleozoïcum leefden, leken vreemd genoeg geen mediane ogen te hebben.

Ontdekking
Tenminste, dat was tot voor kort de veronderstelling. Totdat onderzoekers de trilobiet Aulacopleura koninckii, waarvan een deel van de kop was afgeschraapt, aan een nadere inspectie onderwierpen.

Het team ontdekte drie bijna identiek gevormde, donkere, onopvallende kleine ovale vlekjes van dezelfde grootte aan de voorkant van de kop. Deze drie structuren lopen evenwijdig aan elkaar en waaieren aan de onderkant iets uit. Alle drie de vlekken worden gekenmerkt door een gladde, duidelijke omtrek en een uniforme, donkerbruine kleur. “Deze plekken onderscheiden zich duidelijk van de vlekken die ontstaan door verval of fossilisatie,” legt onderzoeker Brigitte Schoenemann uit. “In plaats daarvan komt het precies overeen met hoe de overblijfselen van eenvoudige mediane ogen eruitzien.

Mediaan oog
Het betekent dat trilobieten mogelijk toch – net als alle andere geleedpotigen én veel naaste verwanten – niet alleen samengestelde ogen hadden, maar ook met een extra set ogen waren uitgerust. “De ontdekking ondersteunt de veronderstelling dat trilobieten oorspronkelijk mediane ogen hadden,” concludeert Schoenemann.

Onopgemerkt
Dat de trilobiet dit geheimpje zolang heeft weten te bewaren, is opvallend. Zoals gezegd is de trilobiet al ruim een eeuw uitgebreid bestudeerd. Bovendien zijn er ondertussen al meer dan 22.000 soorten ontdekt. Ondanks dat, zijn de mediane ogen al die tijd onopgemerkt gebleven. Toch is dit wel te verklaren. Ze zitten – in gefossiliseerde trilobieten – namelijk enigszins verstopt.

Verstopt
De wetenschappers gaan ervan uit dat de mediane ogen kenmerkend waren voor het larvenstadium, zo leggen ze in hun studie uit. Bovendien bevonden ze zich onder een transparante laag van het schild. Gedurende het fossilisatieproces wordt deze laag echter ondoorzichtig. “Dit heeft er beide toe bijgedragen dat de ontdekking van de extra set ogen zo lang op zich heeft laten verwachten,” aldus Schoenemann.

Meer over trilobieten
Trilobieten zijn te herkennen aan een verkalkt exoskelet aan de rugkant van het lichaam. Ze hadden een halvemaanvormige kop die wel wat weg had van de hedendaagse degenkrab. Hoewel de dieren onderhand zijn uitgestorven, waren ze een succesvolle soort in termen van evolutie. Ze hebben meer dan 250 miljoen jaar weten te overleven; langer dan de dinosauriërs.

Het betekent dat trilobieten waarschijnlijk meerdere verborgen ogen hadden. Toen de onderzoekers de trilobiet Cyclopyge sibilla bestudeerden, vonden ze namelijk ook drie mediane ogen op het voorhoofd, precies tussen de twee samengestelde ogen in. Deze waren bovendien zelfs uitgerust met lenzen die vergelijkbaar zijn met die in menselijke ogen. Dit wijst erop dat deze trilobiet waarschijnlijk beter kon zien dan zijn naaste verwant Aulacopleura koninckii, die – in tegenstelling tot Cyclopyge sibilla – enkel op de bodem leefde.

Variërend
Kortom, uit de bevindingen blijkt dat trilobieten veel meer ogen hadden dan gedacht; waarschijnlijk minstens vijf! Al kan dat aantal ook nog weleens hebben gevarieerd. De onderzoekers denken dat geleedpotigen namelijk op verschillende momenten in de evolutie over een verschillend aantal mediane ogen beschikten. “Het oorspronkelijke aantal mediane ogen is twee,” vertelt Schoenemann. “Daarnaast hadden zeer primitieve geleedpotigen er waarschijnlijk vier. Hedendaagse dieren, zoals insecten en schaaldieren, zijn uitgerust met drie mediane ogen.”

Al met al zijn de onderzoekers er dankzij hun eigen scherpe oog in geslaagd het mysterie van de ontbrekende mediane ogen bij trilobieten op te lossen. Maar dit breidt niet alleen onze kennis over deze uitgestorven prehistorische zeedieren uit. Dat het aantal mediane ogen in geleedpotigen varieerde, zou mogelijk de evolutionaire classificatie van archaïsche geleedpotigen kunnen vergemakkelijken. “Met behulp van het aantal mediane ogen kunnen we nu mogelijk eenvoudiger de positie van een geleedpotige in de evolutieboom bepalen,” besluit Schoenemann.

Er is een "Pompeii van de zee" ontdekt met perfect bewaarde fossielen: het dateert van 515 miljoen jaar geleden

Abderrazak El Albani, University of Poitiers

Allerlei families van trilobieten verschijnen plotseling in het Cambrium en zien er al direct zeer complex uit. Van evolutionaire voorouders is vooralsnog geen spoor te bekennen.

Overblijfselen van trilobieten bewaard gebleven dankzij gevonden vulkanische as: de studie

We zijn in Aït Youb, in de regio Souss-Massa in Marokko. Hier heeft een team onderzoekers onder leiding van Abderrazak El Albani fossielen ontdekt van twee nieuwe soorten trilobieten die gedateerd kunnen worden op ongeveer 515 miljoen jaar geleden. Tot zover niets vreemds, behalve dat de staat van bewaring van deze trilobieten de beste is die ooit is gevonden.

Zoals we in de inleiding al zeiden, was het tot nu toe onmogelijk om de interne structuren van trilobieten goed te bestuderen: meestal fossiliseert alleen het exoskelet. In het geval van Aït Youb daarentegen heeft vulkanische as van uitbarstingen uit het Precambrium het mogelijk gemaakt om exemplaren te vinden die bijna perfect bewaard zijn gebleven, zo goed zelfs dat ze doen denken aan de vondsten in Pompeii. Aan de andere kant, zo stelt El Albani, is de dynamiek die ten grondslag ligt aan het behoud ervan vrijwel hetzelfde.

Wat is er gebeurd met de trilobieten die ontdekt zijn in Aït Youb?

Volgens El Albani en zijn team hebben we de uitstekende conservering van de trilobieten in feite te danken aan een snelle vulkaanuitbarsting, die de exemplaren begroef en in zeer korte tijd gevangen hield. Sommige trilobieten zijn al opgerold, terwijl andere zich voorbereiden om te ontsnappen, en er zijn enkele exemplaren die zelfs het spijsverteringskanaal vol sediment laten zien dat kort voor de uitbarsting is ingenomen. Als je bedenkt dat het tot voor kort niet mogelijk was om de interne anatomie van een trilobiet te bestuderen, begrijp je heel goed de revolutionaire betekenis van deze ontdekking.

Om deze fossielen beter te kunnen bestuderen, gebruikten de onderzoekers röntgenmicrotomografie, zodat ze een driedimensionale weergave konden bekijken zonder de exemplaren uit de rotsmatrix te halen.  Dit is een innovatieve techniek waarmee anatomische details kunnen worden bekeken zonder de vondsten in gevaar te brengen. Het onderzoek, gepubliceerd in het tijdschrift Science, onthulde ook tot nu toe onbekende anatomische structuren van trilobieten, waaronder sporen van mondaanhangsels en zacht weefsel.

Een bijna perfecte bewaring... zoals in Pompeii

El Albani zelf noemde de vondst in Marokko een “Pompeii van de zee”, en met een goede reden. Zoals we hebben gezien, creëerde de vulkanische as driedimensionale mallen van de trilobieten, waardoor ze in feite bevroren werden in de tijd. Maar terwijl er in het geval van Pompeii zo'n 2000 jaar is verstreken, is er hier 515 miljoen jaar verstreken en daarom was het gebruik van röntgenmicrotomografie bijzonder nuttig.

Ontdekkingen zoals deze zorgen voor een beter begrip van het belang van vulkanische asafzettingen voor het behoud van fossielen, maar tegelijkertijd testen ze de technologische vooruitgang in het bestuderen van het verleden. In staat zijn om trilobieten van 515 miljoen jaar geleden te analyseren vertegenwoordigt een onmisbare kans, die in het verleden onmogelijk was: vanuit een bepaald oogpunt is het ook een vorm van respect voor deze oude fossielen. Laten we niet vergeten dat ze een groot deel van de geschiedenis van onze planeet hebben overbrugd en bijna perfect bewaard zijn gebleven.

Allerlei families van trilobieten verschijnen plotseling in het Cambrium en zien er al direct zeer complex uit. Van evolutionaire voorouders is vooralsnog geen spoor te bekennen.

NASA heeft twee asteroïden ontdekt die dicht langs de aarde kwamen: planetaire radarbeelden

Unsplash - Not the actual photo

De ruimte van het zonnestelsel is bijna helemaal leeg, zelfs als je rekening houdt met de hemellichamen die rond de zon draaien, maar minder dan 0,15 procent van de massa van het hele stelsel uitmaken. Toch is het niet zo onwaarschijnlijk dat twee hemellichamen heel dicht bij elkaar kunnen zijn, zoals gebeurde met twee asteroïden die dicht bij de aarde passeerden, slechts een paar dagen na elkaar. De ontdekking werd gedaan door wetenschappers van JPL dankzij de Goldstone Solar System Radar, die er ook in slaagde om enkele beelden van deze asteroïden, die beide potentieel gevaarlijk zijn, vast te leggen.

Eerste waarneming: asteroïde van 1,5 kilometer passeerde dicht bij de aarde

Eén van de doelstellingen van op de ruimte gerichte radars is het relatief vroeg detecteren van de passage van asteroïden vlakbij de aarde. Onlangs werd bijvoorbeeld asteroïde 2011 UL21 slechts 13 dagen vóór zijn dichtste nadering tot onze planeet gedetecteerd. Nu hebben we het over een relatief groot hemellichaam, ongeveer 1,5 kilometer breed en potentieel gevaarlijk voor de aarde.

Gelukkig zijn er momenteel geen risico's, zoals bevestigd door wetenschappers van het Jet Propulsion Laboratory van NASA. 2011 UL21 passeerde feitelijk op 27 juni 2024 op een afstand van ongeveer 6,6 miljoen kilometer, oftewel ongeveer 17 keer de afstand tussen de aarde en de maan. Maar dat is nog niet alles: dankzij de Goldston Solar System Radar heeft JPL ontdekt dat 2011 UL21 niet één enkele asteroïde is, maar een systeem van twee asteroïden in een baan om de aarde. Een beetje zoals wat er gebeurde met Dinkinesh, het kleine binaire systeem dat werd geïdentificeerd door de Lucy-missie die eind 2023 richting Jupiter reisde.

Tweede waarneming: asteroïde passeerde veel dichter bij onze planeet

NASA/JPL-Caltech

Slechts twee dagen na de waarneming van 2011 UL21 op zo'n 6,6 miljoen kilometer van de aarde, hebben wetenschappers van JPL een tweede asteroïde gezien, dit keer veel dichter bij onze planeet. Het gaat om asteroïde 2024 MK, die slechts 150 meter breed is en dus veel kleiner dan het hemellichaam dat eerder werd waargenomen. 2024 MK wordt echter ook beschouwd als een potentieel gevaarlijke asteroïde en deze asteroïde passeerde slechts 295.000 kilometer van de aarde. Met andere woorden, ongeveer driekwart van de afstand die ons van de maan scheidt.

Dergelijke naderingen zijn vrij zeldzaam en komen ongeveer elke 20 jaar voor. Hoewel ze in strikte zin niet gevaarlijk zijn voor onze planeet, zijn ze essentiële informatiebronnen voor ons begrip van het zonnestelsel. De eenvoudige passage naar 295 duizend kilometer van de aarde verminderde bijvoorbeeld de baan van 2024 MK rond de zon met ongeveer 24 dagen.

Potentieel gevaarlijke asteroïden: wat betekent dat?

Er zijn verschillende factoren waarmee wetenschappers bij NASA en andere ruimtevaartorganisaties rekening houden om een ​​asteroïde als "potentieel gevaarlijk" te definiëren. Hiervan zijn de volgende zeer belangrijk:

•  de afmetingen, met een diameter van minimaal 140 meter;
• de afstand tot de aarde, binnen 0,05 Astronomische Eenheden, of ongeveer 7,5 miljoen kilometer;
• de naderingssnelheid, de onregelmatige vorm en samenstelling, als secundaire factoren.

Zoals je kunt zien, zijn potentieel gevaarlijke asteroïden niet de asteroïden die een gevaar in de strikte zin van het woord voor de aarde inhouden, een beetje zoals in het geval van 2011 UL21 en 2024 MK. Kortom, we hebben het niet over Chicxulub dat 66 miljoen jaar geleden leidde tot het uitsterven van niet-aviaanse dinosaurussen, maar over hemellichamen die NASA van plan is te observeren tijdens hun passage op een bepaalde afstand van onze planeet. In de hoop dat deze afstand altijd groter zal zijn.

THIS SCORCHINGLY HOT PLANET THAT RAINS DOWN GLASS APPARENTLY ALSO SMELLS LIKE ROTTEN EGGS

A study published Monday shows evidence for the toxic, nasty-smelling gas hydrogen sulfide in a nearby exoplanet.

BY DORIS ELÍN URRUTIA

 

Roberto Molar Candanosa/Johns Hopkins Univeristy

A study published Monday in the journal Nature shows evidence for the presence of the toxic, nasty-smelling gas hydrogen sulfide in HD 189733 b. The knowledge isn’t just for sensorial space exploration: It shapes how astronomers understand the evolution of all planets under the Sun – err, stars.

Sewer gas on another world is a helpful clue. The chemical compound aids the construction of more complex molecules, including those essential to life. “Sulfur is a vital element for building more complex molecules, and — like carbon, nitrogen, oxygen, and phosphate — scientists need to study it more to fully understand how planets are made and what they’re made of,” Guangwei Fu, lead researcher and astrophysicist at Johns Hopkins University, said in an announcement about the new paper.

In the case of this particular exoplanet, Fu said, researchers aren’t looking for life. Astronomers already know this world, located 64 light years away from Earth, is inhospitable. Temperatures reach 1,700 degrees Fahrenheit there, and its glass-filled wind would humble any terrestrial storm, thanks to its 5,000 mph winds.

“We’re not looking for life on this planet because it’s way too hot, but finding hydrogen sulfide is a stepping stone for finding this molecule on other planets and gaining more understanding of how different types of planets form,” Fu added.

HD 189733 b is one of many exoplanets analyzed through a technique called the transit method. Astronomers glean details about it as the gas giant passes in front of its parent star. HD 189733 b is one of the nearest known “hot Jupiters” to Earth, making it a scientifically-rich object.

According to NASA, there are now more than 5,600 confirmed exoplanets in the Milky Way.

5 Fascinating Facts On The Sleek USAF U-2 Dragon Lady Spy Plane

By Mike Scanlon

SUMMARY

With its sleek design and technological prowess, the U-2 spy plane, often referred to as the "Dragon Lady," represents one of the most iconic aircraft in military aviation history. Developed in the early 1950s in response to increasing nuclear and long-range nuclear missile threats from the USSR during the Cold War, the high-flying aircraft changed the landscape of aerial reconnaissance and espionage, providing the United States with unmatched intelligence-gathering capabilities. In this article, we take a look at a healthy handful of interesting facts about the legendary Dragon Lady.

1. Secretive U-2 test flights caused a spike in UFO sightings

Fiery objects in the sky baffle pilots below

When given just eight months to design an aircraft capable of flight above 70,000 feet (21,336 m), Lockheed Chief Engineer Clarence "Kelly" Johnson (pictured below) and his team at the secret Skunk Works plant in California delivered what was essentially a jet-powered glider, the CL-282, which would later be dubbed the U-2. As time was of the essence, the design was quickly approved by the CIA, and production was immediately underway.

Completed units were delivered to the highly classified Nevada Test and Training Range, also known as Area 51, for testing under tremendous secrecy. According to the CIA, high-altitude testing of the aircraft led to a significant spike in UFO reports. With most commercial flights flying under 20,000 ft (6,096 m) and military aircraft below 40,000 ft (12,192 m), pilots of these aircraft were dumbfounded by the object flying above them at 60,000 ft (18,288 m), a feat considered impossible at the time

Under certain conditions, the sun would reflect off the then-silver wings of the U-2, which made them appear as "fiery objects" flying high above to pilots below. The overwhelming reports of UFOs led to the USAF's Operation Blue Book, also known as Project Blue Book, based at Wright-Patterson Air Force Base, Ohio.

Operation Blue Book gathered all the reports of UFOs and cross-referenced them against U-2 flight logs. USAF investigators would subsequently dismiss the reports as "natural phenomena," unable to reveal the truth behind these sightings. U-2 (and later OXCART) are believed to have been the source of over half of the UFO reports from the late 1950s through the 1960s.

Soaring to the edge of space at altitudes over 70,000 feet (21,336 m), U-2 pilots are required to wear specialized space suits, also known as full-pressure suits, made by the same company that supplies NASA, to ensure their survival in the harsh environment of the upper atmosphere. The model S1034 space suit serve as a personal life support system, should the cockpit pressurization system fail, and are key to safeguarding the pilots against decompression sickness, hypoxia, and exposure to the near-vacuum conditions of high altitudes.

The suit's engineering is nothing short of remarkable, meticulously designed to balance safety, functionality, and comfort, highlighting the extreme conditions U-2 pilots face. It features a distinct helmet equipped with a communications system, a visor that can be heated to prevent fogging and an oxygen supply system that guarantees the pilot has a steady flow of breathable air. Furthermore, the suit includes a cooling garment integrated with tubing to circulate temperature-controlled water, ensuring the pilot remains comfortable during long missions.

3. It's like riding a bicycle...that weighs 16,000 pounds with massive wings

The U-2 has a very unique set of wheels

Designed to minimize aircraft weight and promote higher altitude, the U-2's unique landing gear configuration distinguishes it from most conventional aircraft. Unlike typical aircraft that utilize a tricycle arrangement, the U-2 employs a bicycle-style arrangement with two sets of wheels positioned along the longitudinal axis of the fuselage.

This setup includes a forward main landing gear located just behind the cockpit and an aft main landing gear near the tail and connected to the rudder to provide steering functionality during taxiing.

To maintain balance during takeoff, the U-2 utilizes outrigger gears, known colloquially as "pogos." These removable wheels are attached to mid-wing sockets and jettisoned during takeoff, falling to the runway. Upon landing, once the aircraft comes to rest on its wingtip, the pogos are reinstalled for taxiing. Suffice it to say that U-2 takeoff and landing procedures are not for the faint of heart, as shown in the X link below.

4. Taming the Dragon Lady

The U-2 is considered by many to be the most difficult airplane to fly

• https://youtu.be/eiA6u0mT4oI

The U-2 is widely considered the most difficult airplane to fly. Mastery of the U-2 requires an exceptional level of expertise, dexterity, and resilience, qualities that define the elite group of pilots (fewer than 1500) capable of taming the "Dragon Lady." There are several factors contributing to its notoriously difficult handling, making it a true test of a pilot's skill and endurance.

Firstly, the U-2 operates at extreme altitudes, often above 70,000 ft (21,336 m), where the air is thin and the margin for error is minimal. The aircraft's design prioritizes performance at these altitudes over ease of control, leading to a unique combination of a highly sensitive control system and low maneuverability.

Secondly, the U-2's takeoff and landing phases are particularly challenging. During takeoff, the aircraft's massive wings and lightweight frame make it highly susceptible to crosswinds and other atmospheric disturbances.

Landing the U-2 is equally daunting due to the bicycle-like landing gear configuration, as described above. Landing the U-2 requires exceptional skill and coordination, as the pilot must balance on the bicycle gear while reducing speed and altitude, with the assistance of a chase car driven by another pilot as shown below, providing real-time feedback and assistance. To make matters worse, visibility is limited during the landing because of the plane's unique design.

Moreover, pilots must endure long missions that can extend beyond ten hours, confined to a pressurized suit similar to those worn by astronauts. This suit is necessary due to the harsh conditions at cruising altitude and introduces additional challenges in terms of physical comfort, fatigue management, and sustenance.

The U-2 is still in service but the US Air Force plans to retire the iconic aircraft in 2026.

5. What do U-2 pilots eat during flight?

Hint: The Dragon Lady isn't much of a cook

Flying sorties up to and beyond ten hours, U-2 pilots often need to eat and drink during flight. However, at such extreme altitudes, doing so isn't as simple as it sounds. According to U-2 Support Launch and Recovery Supervisor Staff Sergeant David Labarge, U-2 pilots are instructed that once their helmet is locked down, they are not to open it until they land. Failure to heed this warning could have disastrous consequences.

As long as the cockpit is pressurized, theoretically, a U-2 pilot could safely open their helmet to eat, scratch their nose, or have a sip of water. However, Sgt. Labarge cautions that, at such high altitudes, were a pilot to open their helmet and the cockpit pressurization system suddenly failed, "the blood in their body would instantaneously boil, leading to instantaneous death."

"The blood in their body would instantaneously boil, leading to instantaneous death."

As such, the helmet is designed with a feeding port through which pilots can drink from a gravity-fed water bottle and eat "tube food, made by the same people who make traditional meals-ready-to-eat (MRE).

The food is squeezed from a toothpaste-like tube through the helmet's feeding port directly into the pilot's mouth.

Dinner service aboard a U-2 offers a variety of choices, including beef stroganoff, truffle mac and cheese, chicken alfredo, peaches, pears, chocolate pudding, and even caffeinated cinnamon applesauce. A heater inside the aircraft ensures their meatloaf-in-a-tube is nice and hot. Bon Appétit!

Failed Thrusters, Helium Leaks, and a Hard Deadline: Inside NASA’s Decision to Keep Boeing’s Starliner At the ISS

Does it still count as being "grounded" when you're in space?

BY KIONA SMITH

 

Maxar/Getty Images

Inverse has all the details about why it’s taking so long to bring Starliner home, how the not-stranded-but-definitely-delayed crew is spending their time in orbit, and why the spacecraft has to leave ISS by mid-August.

AN ABUNDANCE OF CAUTION

Boeing and NASA don’t believe that any of Starliner’s thrusters are damaged, say Stich and Nappi speaking at a press conference on Wednesday. If Starliner had to leave the International Space Station immediately (maybe because of a collision with a piece of satellite debris, like the near-miss that caused the crew to take shelter aboard Starliner earlier this week), the ship could get its crew home safely, according to Nappi.

“If we were to have to do that today, we would just perform a nominal undocking and return,” Nappi told reporters during a press conference on Wednesday.

The extensive tests keeping the spacecraft docked at ISS, they said at the press conference, are a chance for engineers to figure out exactly why five of Starliner’s 28 maneuvering thrusters (technically called the Reaction Control System, or RCS) failed while the spacecraft was docking with the International Space Station on June 6. Starliner’s service module — which houses the thrusters — is designed to burn up during re-entry to Earth’s atmosphere, so once the ship heads home, engineers will lose their chance to poke at the problem.

Boeing and NASA also want to be extremely sure there’s actually nothing wrong. “We don’t believe that we have damaged thrusters, but we want to fill in the blanks and run these tests to assure ourselves of this,” Nappi says.

Stich adds, “Really, what we're doing is just taking the time to make sure that we have looked under every rock and every stone, just to make sure that there's nothing that would surprise us.”

STARLINER RECAP: FAILED THRUSTERS AND HELIUM LEAKS

During its rendezvous with ISS on June 6, five of Starliner's 28 maneuvering thrusters failed. The crew and mission control managed to get four of them back online, but one (thruster B1A3) refused to cooperate, first sputtering out just 11 percent of its normal thrust, and then nothing at all. B1A3 will remain shut off for the rest of the mission.

The thruster issues appeared after Starliner had to fire its thruster more — and more often, in several short pulses — than engineers had expected.

And then there are the helium leaks. Starliner uses helium to pressurize its thrusters, and some of that helium is leaking out around the O-rings used to seal the area where the helium — and two lines that carry rocket propellant — pass through a flange and into the thruster.

"Helium was getting out from that flange area and somehow getting around that O-ring," says Nappi "The design should have been sufficient, but there's obviously something going on in that cavity that we don't understand."

SO MUCH TESTING, SO LITTLE TIME

Last week, Starliner test-fired its thrusters while docked to the ISS, using the station’s flight control system to measure how much thrust the thrusters were actually thrusting (Inverse would certainly not like to apologize for that sentence, thank you).

Meanwhile, at White Sands Missile Range in New Mexico, engineers have test fired several thrusters, trying to re-create the extreme temperatures and workload Starliner’s thrusters faced during flight. Those tests are now complete, but engineers still need to physically check the tested thrusters for damage and analyze a tremendous collection of data about their performance. Next, engineers will be repeating the process — but this time they’ll be simulating the “downhill” phase of the mission, or the return to Earth.

“We really wanted to get that testing completed and actually physically inspect the thruster before we committed to the nominal undocking,” says Stich. “I think there's ways from what we've learned from this flight to change the number of pulses required for the rendezvous and docking phase to not put such demand on the thrusters.”

Engineers are also working on the helium leak, which means smearing grease on spare flanges, tossing debris into them, and blasting them with heat to test possible causes for the leak. They also need to make sure that the thrusters are still getting enough helium to keep them pressurized — at least enough to work reliably and safely.

“We would like to duplicate that flange design on the ground under a controlled test and see if we can't make it leak, and experiment with some larger seals or maybe a different seal material that might not be as susceptible to degradation from the propellant,” said Nappi.

“THE NATURE OF WHAT WE DO”

To bystanders, it seems like an alarming situation: a new spacecraft launches with its first crew, only for its thrusters to fail and start leaking helium pressurizer. But for test pilots like Starliner test commander Butch Wilmore, it’s another day at the office.

“Human spaceflight is not easy. There have been multiple issues with every spacecraft that has ever been designed, and that's the nature of what we do,” said Wilmore.

Nappi and Stich repeated a similar message to reporters.

“We knew that there would be some learning from this flight test. We've learned a great deal from how the hardware works, how our processes work, and how we can improve the things that we're doing,” said Nappi. “As engineers, we test, we learn, we fix, and that’s exactly what we’re going through.”

MAKE ROOM, MAKE ROOM!

The testing and analysis are likely to take another couple of weeks, at least, which means Wilmore and Starliner test pilot Suni Williams probably won’t be bidding farewell to the ISS until at least the end of July – and Stich described that possible timeframe as optimistic. But Starliner needs to be on its way by mid-August, when a SpaceX Crew Dragon is set to bring a new quartet of spacefarers (astronauts Zena Cardman, Nick Hague, and Stephanie Wilson, as well as Russian cosmonaut Aleksandr Gorbunov) to the ISS.

The SpaceX Crew Dragon spacecraft that carried Crew-8 (astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, as well as Russian cosmonaut Alexander Grebenkin) to the ISS is still docked at the station, waiting for Crew-8 to hop aboard and fly it home. Before they leave, though, they need to meet and brief their replacements, a process NASA calls a handover. Crew-9 will dock their Crew Dragon with ISS and come aboard before Crew-8 leaves. At the moment, that’s a problem, because Starliner is sitting in Crew-9’s parking spot.

That gives NASA and Boeing a deadline for finishing their tests and either deeming Starliner fit to fly home or making other arrangements.

“The beautiful thing about the commercial crew program is that we have two vehicles, two different systems, that we could use to return the crew,” said Stich, referring to Starliner and Crew Dragon. “We have a little more time to go through the data and decide whether we need to do anything different but the prime option today is to return Butch and Suni on Starliner.”

“LIKE COMING BACK HOME”

For now, Wilmore and Williams are safe and sound on the ISS, where they’ve been pitching in with maintenance and science experiments.

“Butch and I have been up here before, and it feels like coming back home,” says Williams. “We've been integrated right into Expedition 71. We've been doing science with them, maintenance, and some major maintenance that has been waiting for a little while.”

Wilmore recently tested NASA’s Moon Microscope, a handheld 3D-printed microscope that’s part of a medical kit that could help future lunar explorers diagnose illnesses and make sure their food, water, and quarters aren’t contaminated. And Williams sequenced DNA while zipping around Earth at 17,500 miles per hour. The pair also helped swap out a urine processor pump. (Never a dull moment aboard ISS, and no lack of variety, either.)

Stich says the whole ISS crew is comfortable and has plenty of supplies — including things like food and clothing — to last the duration. A Northrop-Grumman Cygnus cargo spacecraft is scheduled to launch in early August, bringing new supplies and probably some extra items from home for the Starliner crew, if they’re still aboard. Meanwhile, this isn’t even close to the most crowded the ISS has ever been.

In fact, situations like this one may become more common over the next few years. Stich, paraphrasing retired astronaut Ken Bowersox, said earlier today that now that ISS can provide electricity to docked spacecraft, it can serve as a sort of temporary hangar for engineers to troubleshoot spacecraft in orbit.

Meanwhile, Williams and Wilmore sound calm and confident – which is also part of their job.

“I have a really good feeling in my heart that the spacecraft will bring us home,” says Williams.

SpaceX Falcon 9 rocket suffers failure during Starlink satellite launch (video)

SpaceX's workhorse Falcon 9 rocket suffered a rare anomaly on Thursday night (July 11).

The incident occurred during a launch of SpaceX's Starlink internet satellites from Vandenberg Space Force Base in California. The Falcon 9 performed well initially; its two stages separated on time, and the first stage came down for a landing on a drone ship about eight minutes after liftoff as planned.

But the rocket's upper stage, which was hauling 20 Starlink spacecraft to low Earth orbit, encountered a problem — a leak of liquid oxygen, which had serious repercussions for the mission.

"After a planned relight of the upper-stage engine to raise perigee — or the lowest point of orbit — the Merlin Vacuum engine experienced an anomaly and was unable to complete its second burn," SpaceX wrote in an update today (July 12). (The Falcon 9's upper stage is powered by that single engine; the first stage sports nine Merlins, which explains the rocket's name.) 

SpaceX engineers worked to get the 20 Starlink satellites — 13 of which were capable of beaming service directly to cell phones — to raise their orbits using their onboard ion thrusters. But the hill was too steep to climb, according to the company.

"At this level of drag, our maximum available thrust is unlikely to be enough to successfully raise the satellites," SpaceX wrote in the update. "As such, the satellites will reenter Earth’s atmosphere and fully demise. They do not pose a threat to other satellites in orbit or to public safety."

The Falcon 9 is the most prolific rocket flying today, with 69 launches under its belt already in 2024. It's known for its reliability; before Thursday night, the Falcon 9 had suffered only one full in-flight failure in its storied history, which occurred during the launch of a robotic Dragon cargo capsule toward the International Space Station (ISS) in June 2015.

The Falcon 9 is also human-rated; it has launched 13 crewed missions to date, nine of which have sent astronauts to the ISS for NASA. It's unclear how Thursday's failure will affect the rocket and its manifest at this point; SpaceX will first need to figure out exactly what happened and how to address the issue — an effort that's already underway.

"SpaceX will perform a full investigation in coordination with the FAA [Federal Aviation Administration], determine root cause, and make corrective actions to ensure the success of future missions," SpaceX wrote in today's update. "With a robust satellite and rocket production capability, and a high launch cadence, we’re positioned to rapidly recover and continue our pace as the world’s most active launch services provider."

Most Falcon 9 missions these days service the giant and ever-growing Starlink megaconstellation, which currently consists of more than 6,100 operational satellites; 49 of the 69 Falcon 9 launches so far in 2024 have been dedicated Starlink missions.

Editor's note: This story was updated at 4:30 p.m. ET on July 12 with the news from SpaceX that all 20 Starlink satellites will be lost due to the Falcon 9 upper-stage failure.

Former Area-51 Pilot Claimed He Flew Re-Engineered UFO To 500 Feet But It Crashed & Broke His Legs

Before 2013,  Area-51 had only been in the conspiracies. People ridiculed those who claimed to have worked in this highly classified US Air Force facility. Thanks to archivist Jeffrey Richelson who made it possible for the government to finally admitted that  Area-51 is a real place in the Mojave Desert about 100 miles north of Las Vegas. A few years back, ApexTV, famous for their mysterious content, did an interview with a fellow named Robert Miller who piloted an alien spacecraft at Area-51 telepathically, before crashing and breaking both his legs.

His story is worth reading as who knows what secrets may open up later in the future and become the reality in our life.  Area-51 is one of the world’s most secretive places controlled by the US Air Force, which is claimed to be the storehouse of alien spacecraft, where their technology is being developed. It has been actively working since 1955 (as officially stated), which was the study point of UFOs in the 50s. Since then, the place has become a pilgrimage for alien hunters and UFO researchers.

In December 2017, Robert Miller did an interview with ApexTV where he revealed secrets of the inner workings of  Groom Lake. According to Miller, aliens and extraterrestrial crafts are being kept inside  Area-51, and he alleged to have been part of a top-secret project in which he was chosen to pilot a reverse-engineered UFO.

The video shows a bald man in cargo shorts claiming he flew an alien spaceship telepathically, but the sound quality is terrible. Miller cliamed to have hidden the fact that he worked in  Area-51 from his closest relatives, but his mother had the slightest that idea about his job. His purpose for recording the video is to remove this secret from his conscience, and he knew the circumstances of the reveal that the government would come after him.

Miller grew up in a small town in Southern Nevada, and his father was an aerospace engineer who taught him to fly aircraft which helped him become a licensed pilot at the age of 15. He later joined Marine Corps as a pilot, where he was considered one of the top pilots. By the time he became 18, he was planning to retire from the Marine Corps and find a normal job back home and thinking to start a family.

Everything changed when he received an offer letter about his new job as a test pilot in a secret program. “I thought, great. It also said, a plane would be picking me up at the Las Vegas airport Friday the second at three AM to take me there. So we flew out there in the middle of the night and two men in black suits escorted me into an underground building. It was built on the side of a hill and yes, the men in black are real. Believe me, they’re real,” Miller said.

He continued explaining the place which had long hallways and many doors on each side. Miller added: “We went down several flights of stairs, must have been far underground at that point. They showed me into a small room with a single bed and a desk.” He was then locked inside the room by those men.

Miller looked in one of his drawers and found a booklet, titled something like “Working at Grim Lake” that mentioned that there were 1,200 other employees. He claimed only insiders decide whom to recruit to work in  Area-51. “I assumed that my father invited me and this is where he had been working when I was a kid. He had long, long since retired by the time I got there, and I wasn’t sure what was in store for me now.”

Miller was appointed as a test pilot for the so-called alien technology that was allegedly recovered from the crafts that crashed in 1947. Like any other whistleblower, he also said that they had already reversed engineering the alien spacecraft technology. He was going to be the first person to pilot the craft.

“Also, they threatened me again, if I told anybody, even my family, there would be dire consequences for all. I asked them what were the origins of the craft they found and they really thought it just was from another country. They told me not of this world and the beings that engineered it were extra-dimensional. They said the beings were still alive and were being kept in an undisclosed location in a facility,” Miller revealed.

Miller described a large disc-shaped craft about “50 feet from end to end, edge to edge” standing in the middle of the warehouse. It had a transparent dome at the top. He assumed that it was his testing vehicle. The engineers who worked on the craft technology told him that it was powered by an anti-matter reactor. The reactor produced bursts of dense energy that could generate wormholes and make the craft travel near the speed of light.

“They then said that my test flight was going to be delayed until the next day because they had to explain to me everything I needed to know in order to be able to pilot this thing. Now I’m just going off of what I can remember. There was a lot of specifics, gauges, and things but as I’ve gotten older, so I’m telling you as much as I can possibly remember. I do remember they brought me inside the craft.”

According to Miller, the alien spacecraft had a room for only one person. The cockpit had a seat, no joystick, no steering wheel, and no other controls, only a helmet. He told that the craft operates only telepathically.

“The helmet measured my brainwaves and

was to control the craft by simply thinking about it. After a hard night of trying to sleep, thinking about this, morning came. And it was finally time to take the craft for the first test flight. They brought out a tarp and ordered everyone working on the base to go inside. They wanted to keep everybody not knowing about this secret technology to a bare minimum.”

He put on the helmet and followed the guidance as the craft was only going to operate by analyzing his brain waves. He had to imagine the craft floating off the ground but instead, he imagined being a part of the craft. After that, he began thinking of himself floating off the ground. “I felt vibrations from the anti-matter reactor below me as it started to fire up.”

He was instructed to take the craft up to 1000 feet. He succeeded in taking it to 500 feet but shockingly, the engine stopped and Miller started losing altitude. He found no safety feature, and no seat ejection system was there in the craft. He kept imaging the craft floating but eventually, it hit the ground and Miller received serious injuries.

Miller said he fell unconscious and then woke up in the medical ward, where he was told by another man in a black suit that the craft mysteriously disappeared just before crashing and everyone at the base simply “called it a day” and went inside. Then in the middle of the night, they heard a loud crashing noise outside. Running out to see what happened, they saw the craft had crashed in the spot it was about to crash a while earlier during the day.

“I was inside the pilot’s seat unconscious, both my legs were shattered. The scientists had hypothesized that the craft had actually time traveled to a point in time, several hours later. They had me sign a non-disclosure, the third one, stating, since the first meeting, I would not tell anybody as long as I lived and making this video. Well, as you can see, I have gone against this NDA contract because I feel that the public needs to know about this.”

A similar claim of testing a re-engineered ET craft has another witness named Bill Uhouse who testified that it required a good amount of time for a person to train in order to operate the disc. Besides, its design was so exacting that nothing could be externally installed on it such as machine guns and bombs like in traditional aircraft.

Story by Paul M. Sutter

The sci-fi landscape is littered with wormholes. From Douglas Adam's Hitchhiker's Guide to the Galaxy and Rick and Morty to the Marvel Cinematic Universe, these theoretical constructs allow characters to zip between distant points in the universe as easy as stepping through a doorway.

An Einstein-Rosen bridge is the simplest kind of wormhole. And while it can, in theory, allow you to meet a new friend from a distant part of the universe, there are some important reasons why it won’t let you travel back in time.

Black Holes, White Holes and Wormholes

Let’s start with everybody’s favorite astronomical mystery: a black hole. Despite their fearsome reputation, they’re actually rather simple creature. They have a point of infinite density, known as the singularity, in their centers. They are surrounded by a boundary called the event horizon.

The event horizon doesn’t exist in the same way that the surface of a planet exists. Instead it’s just a mathematical line in the sand that tells you one thing: if you cross within that special distance, you’re trapped forever, because you’ll have to travel faster than the speed of light to escape.

• 'Fuzzballs' Might Be the Answer to a Decades-Old Paradox About Black Holes

And that’s it. That’s a black hole. A singularity and an event horizon. All things that cross the event horizon will never escape back into the universe – things go in and never come out.

Mathematically we can also define the polar opposite of a black hole, which is conveniently called a white hole. White holes also have a singularity, but their event horizons act differently. Anything already on the outside of a white hole (like, the entire universe) can never, ever cross within it, no matter how hard it tries. And anything already inside the white hole will find itself ejected from it faster than the speed of light.

Now when we take a black hole and a white hole and connect their singularities together, we get an entirely new kind of object: an Einstein-Rosen bridge, better known as a wormhole.

What Is a Wormhole?

Wormholes are essentially hollow tubes through space and time that can connect very distant regions of the universe. A star may be thousands of light-years away, but a wormhole can connect that star to us with a tunnel only a few steps long.

Wormholes also have the somewhat mystical ability to allow backwards time travel. If you take one end of the wormhole and accelerate it to a speed close to that of light, it will experience time dilation — its internal “clock” will run slower than the rest of the universe.

That will cause the two ends of the wormhole to no longer be synchronized in time. Then you could walk in one end and end up in your own past. Voilà: time travel.

Read More: 

• Is There a Particle That Can Travel Back in Time?

Can Humans Travel Through Wormholes?

There's just one, tiny, teensy problem with this setup: Einstein-Rosen bridges are indeed wormholes, but the entrance to the wormhole sits behind the black hole event horizon. And the number one rule of black hole event horizons is that once you cross them, you’re never allowed to escape. Ever.

Once you pass through a black hole event horizon, you are forced towards the singularity, where you are guaranteed to meet your gruesome end. In other words, once you enter an Einstein-Rosen bridge, you will never escape.

So, the unfortunate truth with Einstein-Rosen bridges is that while they appear to be magical doorways to distant reaches of the universe, they are just as deadly as black holes. When you enter you can meet other travelers who have fallen in from the other side, and you could even carry on a conversation…briefly, before you both struck the singularity.

There have been attempts to stabilize Einstein-Rosen bridges and make them traversable by somehow getting their entrances to sit outside the event horizon. So far the only way we know how to do this is with exotic matter. If you threaded the wormhole tunnel with matter that had negative mass, then in principle you could have a not-deadly-at-all wormhole.

Alas, negative matter does not appear to exist in the universe, and so our wormhole — and time travel — dreams will have to remain as mere mathematical fantasies.

Astronomers may have found a rare "missing link" black hole in the Milky Way after spotting a group of improbably fast-moving stars at the heart of a nearby stellar cluster. If confirmed, the cosmic juggernaut, known as an intermediate-mass black hole (IMBH), would be the second-largest black hole ever found in our galaxy. 

IMBHs are an extremely rare subset of black holes that are larger than stellar-mass black holes but smaller than supermassive black holes. This means they can be anywhere between 100 and 100,000 times the mass of the sun, according to NASA.

In theory, IMBHs should be just as common as other black hole types. However, astronomers have struggled to locate potential IMBHs or confirm their existence — and they aren't sure why. As a result, IMBHs are often referred to as missing link black holes. While several promising candidates have been detected, none have been proven to be the real deal.

Now, in a recent study uploaded April 4 to the preprint server arXiv, researchers may have uncovered evidence of a large IMBH in the globular cluster Omega Centauri — a compact group of around 10 million stars in the Milky Way located around 17,000 light-years from Earth.

The team compared 500 photographs of Omega Centauri taken by the Hubble Space Telescope and mapped the movements of around 1.4 million stars at the cluster's center. This revealed at least seven stars that "should not be there," researchers wrote in a statement.

This is because these stars were spotted whizzing around fast enough to escape the cluster's gravity and fly off into intergalactic space. But despite this, the stars continue to orbit at breakneck speed near the cluster's center.

"The most likely explanation [for this] is that a very massive object is gravitationally pulling on these stars and keeping them close to the [cluster's] centre," study lead author Maximilian Häberle, a doctoral candidate at the Max Planck Institute for Astronomy (MPIA) in Germany, said in the statement. "The only object that can be so massive is a black hole, with a mass at least 8,200 times that of our sun."

The Milky Way's second-biggest black hole?

Omega Centauri is an unusual entity: It is around 10 times larger than most other globular clusters and is surprisingly flat. It is so massive that you can even see it with the naked eye on dark, clear nights, when it takes up almost as much of the night sky as the moon when viewed from Earth.

Researchers suspect that the cluster likely used to be a dwarf galaxy that orbited the Milky Way, before being pulled into the galaxy's middle. As a result, scientists have often wondered if there could have been a sizable black hole at its heart.

Researchers first proposed the idea of an IMBH in Omega Centauri in 2008, when Hubble revealed how tightly the cluster's stars are bunched at its center. However, at the time, other researchers argued that this could be caused by a swarm of several smaller, stellar-mass black holes.

But the superfast stars highlighted in the new study indicate the existence of an IMBH, the study authors argue.

"This discovery is the most direct evidence so far of an IMBH in Omega Centauri," study co-author Nadine Neumayer, an astronomer at MPIA, said in the statement. If confirmed, it would be the Milky Way's second-largest known black hole behind Sagittarius A* — the supermassive black hole at the heart of our galaxy, she added. "This is exciting because there are only very few other black holes known with a similar mass."

However, the presence of an IMBH in Omega Centauri is not confirmed, and more data is needed to know for certain if it is really there. It is also unclear exactly how large the cosmic entity might be and where it is.

The researchers have been granted time in the future to use the powerful James Webb Space Telescope to peer deeper into the cluster, which means we may not have to wait too long for more evidence of the black hole's existence.

De geur van een planeet niet ver van de aarde ontdekt, waar gesmolten glas naar beneden regent: het ruikt naar “rotte eieren”

ESA/Hubble/Wikimedia commons - CC BY 4.0

We kunnen exoplaneten, die zich buiten ons zonnestelsel bevinden, niet bereiken, maar we kunnen hun geur wel waarnemen: een van hen ruikt naar rotte eieren, zo heeft een nieuw onderzoek ontdekt.

HD 189733 b, de “warme Jupiter" op 64 lichtjaar afstand van ons

Mensen associëren de geur van zwavel met die van rotte eieren, en zouden hun neus moeten dichtknijpen voor de exoplaneet die volgens wetenschappers een atmosfeer heeft die aan deze “geur” doet denken. De buitenaardse wereld in kwestie is een hete exoplaneet van Jupiter genaamd HD 189733 b en is 64 lichtjaar van de aarde verwijderd: een relatief korte afstand, gezien de locatie buiten ons zonnestelsel.

Dankzij de James Webb-telescoop was het mogelijk om te ontdekken dat het omgeven is door een atmosfeer gevuld met waterstofsulfide, waardoor je je gemakkelijk de geur kunt voorstellen die je zou kunnen inademen. HD 189733 b staat dertien keer dichter bij zijn moederster dan Mercurius bij de zon, waardoor het een “helse” planeet is, zoals beschreven. Een bijzonder hete en gasvormige Jupiter in het sterrenbeeld Vosje, die in slechts twee aardse dagen een baan rond zijn ster voltooit. Dit betekent dat de temperatuur bijna 925°C bedraagt: uiteraard onleefbaar voor mensen, afgezien van de geur die het afgeeft. Maar dit is niet de enige bizarre eigenaardigheid van de exoplaneet in kwestie.

Voordat ze in het nieuwe onderzoek de geur van HD 189733 b ontdekten, hadden wetenschappers al onthuld dat er een grote kans bestaat dat er op de exoplaneet buien van gesmolten glas ontstaan, die het gevolg zouden kunnen zijn van winden die het materiaal met een snelheid die kan oplopen tot 800 km per uur zijwaarts duwen, drie keer zo snel als een orkaan van categorie 5 op aarde. Het zijn precies de “eigenaardigheden” van deze buitenaardse wereld die onderzoekers ertoe hebben aangezet er nieuwe aandacht aan te besteden met behulp van de James Webb.

De nieuwe waarnemingen maakten het mogelijk om koolstofdioxide, zware metalen in de atmosfeer, de hoeveelheid water en zuurstof te meten. Zo ontdekten ze de aanwezigheid van waterstofsulfide, dat op onze planeet wordt uitgestoten door vulkanen en ontbindend organisch materiaal. Het is een licht ontvlambaar, schadelijk en kleurloos gas. Voor wetenschappers was het geen echte verrassing: men vermoedde al dat HD 189733 b, als zijnde gasreus, dit molecuul zou kunnen bevatten, dat ook op Uranus en Jupiter aanwezig is. Tot nu toe is dit gas echter zelden buiten het zonnestelsel gedetecteerd, behalve in de ruimte tussen de sterren.

Op zoek naar andere werelden met waterstofsulfide

Guangwei Fu, een astrofysicus aan de Johns Hopkins University, Maryland, noemde de ontdekking van waterstofsulfide op de exoplaneet een belangrijke "opstap naar het vinden van dit molecuul op andere planeten en om beter te begrijpen hoe verschillende soorten werelden ontstaan." Zwavel, zo legde Fu uit, is een essentieel element voor het bouwen van complexe moleculen en is van fundamenteel belang voor de overgrote meerderheid van de levensvormen op aarde.

De aanwezigheid van buitenaards leven op HD 189733 b kan echter vrijwel zeker worden uitgesloten, vanwege de extreem hoge temperaturen, maar ook vanwege de meteorologische omstandigheden. Het feit dat er waterstofsulfide aanwezig is op de exoplaneet doet ons echter denken dat andere werelden buiten ons zonnestelsel dit zouden kunnen bevatten, samen met mogelijke buitenaardse levensvormen. De volgende stap van de onderzoekers zal zijn om andere hete planeten vergelijkbaar met Jupiter te observeren met behulp van de James Webb om de aanwezigheid van hetzelfde gas te evalueren.

Yalçin Yalman Speaks: Unveiling the Turkey UFO Phenomenon

The enigmatic Kumburgaz UFO sightings, recorded between 2007 and 2009, have captivated the imaginations of UFO enthusiasts worldwide. At the heart of this phenomenon is Yalçin Yalman, the man behind the camera. In a recent groundbreaking interview, Yalman has broken his silence, providing new insights into his extraordinary experiences, the beings he encountered, and his predictions for future sightings. This article delves into Yalman’s journey and the broader implications of the Turkey UFO phenomenon.

A Journey Begun in Childhood

Yalçin Yalman’s fascination with UFOs began at the tender age of 12. His early years were marked by vivid dreams and astral journeys, during which he claimed to encounter beings from the Zeta Reticuli star system. These experiences left a profound impact on him, laying the foundation for a lifelong quest to understand and document extraterrestrial phenomena.

At the age of 20, while serving in the military, Yalman had a pivotal encounter. He reported seeing a hexagonal craft in the sky that communicated with him telepathically, urging him to follow it. This incident, coupled with his earlier experiences, cemented his belief in the existence of extraterrestrial life and set him on a path of relentless pursuit.

The Kumburgaz UFO Footage

Between 2007 and 2009, Yalman captured several significant UFO sightings in Kumburgaz, Turkey. Using a Canon XL1 mini DV camera and later a Sony handicam with a telescoping lens, he recorded footage of hexagonal and triangular crafts, some of which appeared to have humanoid figures inside. This footage gained substantial attention and was validated by Turkish authorities and scientists, including TÜBİTAK, Turkey’s scientific and technological research council.

Despite the recognition, Yalman’s journey was fraught with challenges. He faced severe financial difficulties and homelessness, which hindered his ability to continue his work. However, he felt an irresistible compulsion to document these sightings, often feeling as though he was under some form of hypnosis or guided influence.

Astral Contact and Beings from Zeta Reticuli

Yalman claimed to have had ongoing astral contact with beings from Zeta Reticuli. According to him, these beings chose him for a mission to share their existence and information with humanity. He believed these beings protected him from malevolent entities, specifically reptilians from the Orion constellation.

One of Yalman’s most startling revelations was a vision suggesting that an ancient spacecraft was buried under Mount Nemrut in Turkey. This vision, he claimed, could have profound implications for our understanding of extraterrestrial life and ancient human history.

Predictions for Future Sightings

In his interview, Yalman made bold predictions about future UFO sightings. He stated that two large spacecraft would be visible in regions such as Peru, Chile, Brazil, or northern New Mexico by specific dates: July 28 and between August 15-20. He believed these sightings would occur in cloudy weather and hoped that their occurrence would validate his experiences and insights.

Challenges and Validation

Yalman’s claims have been met with skepticism from some quarters. Detractors question the authenticity of his footage, suggesting it could be hoaxed. However, Yalman and his supporters emphasize the multiple witnesses and expert validations that corroborate his accounts.

Throughout his life, Yalman faced numerous personal hardships, including health issues like epilepsy and legal troubles that led to imprisonment. These challenges, however, did not deter him from his mission. He continued to document his experiences and share them with the world, driven by a deep-seated belief in the significance of his work.

Yalçin Yalman’s message to those interested in UFO phenomena is clear: faith and a pure heart are essential for making contact or capturing footage of extraterrestrial entities. He expressed a strong desire to share his knowledge and experiences with humanity before he dies, highlighting the potential role of extraterrestrial beings in shaping human history and future.

In conclusion, Yalçin Yalman’s revelations provide a fascinating glimpse into the Turkey UFO phenomenon. His experiences, while controversial, offer valuable insights into the potential existence of extraterrestrial life and its interaction with humanity. As the dates of his predicted sightings approach, the world will be watching closely to see if his extraordinary claims hold true.

Notably, at the time of the NASA report’s release, the UAP Independent Study Team said that it had not examined or attempted to evaluate any actual incident reports. Instead, it focused on providing recommendations that could help improve future UAP studies while highlighting resources NASA can provide that may assist with such investigations.

Since the NASA report’s publication last year, little additional information has been made publicly available about what progress—if any—the American space agency and its recently appointed Director of UAP Research have made and to what degree NASA will remain involved in the U.S. government’s evaluation of UAP.

Now, almost a year after the NASA team’s findings were released, follow-up inquiries made by The Debrief appear to convey NASA officials’ reluctance to discuss the agency’s status regarding the UAP issue.

Altogether, few NASA officials The Debrief reached out to responded or were willing to speak on the record about any progress the agency has made regarding UAP since the release of last year’s report, although one individual speaking on background did acknowledge that the agency is not historically recognized for having significant involvement in the study of what have traditionally been called unidentified flying objects (UFOs).

The study team’s 36-page report issued last year, which featured several entire pages displaying colorful images of lightning, aurorae, and other luminous phenomena that may occasionally be mistaken for UAP, provided guidance on the types of information that the study team deemed to be most useful in helping to determine the nature and origin of UAPs.

The report also emphasized the importance of improving sensor calibration, obtaining multiple measurements, and leveraging NASA’s expertise in a comprehensive data acquisition strategy within a whole-of-government framework.

“Currently, UAP data analysis is hindered by poor sensor calibration, lack of multiple measurements, insufficient sensor metadata, and absence of baseline data,” the report states. To address these issues, the UAPIST members said NASA should contribute to data collection efforts, using well-calibrated sensors and possibly utilizing multispectral or hyperspectral data in a rigorous acquisition campaign.

The study team’s assessment also advocates for the use of artificial intelligence (AI) and machine learning (ML) as essential tools for identifying and potentially resolving UAP occurrences, although emphasizing that better data will be needed than what currently exists in data made available publicly by both government and civilian agencies. Notably absent from the NASA report had been any investigations or analyses related to recent or past UAP sightings.

Coinciding with the release of its report last year, Daniel Evans, assistant deputy associate administrator for research with NASA’s Science Mission Directorate and one of the UAPIST team members, emphasized NASA’s commitment to understanding what UAP might represent.

“We at NASA believe that understanding UAP is vital,” Evans said last September at a press conference announcing the release of his team’s findings.

“The presence of UAP raises serious concerns about the safety of our skies,” Evans said, adding that “by understanding the nature of UAP, we can ensure that our skies remain a safe space for all.”

The Debrief also contacted Evans last month for feedback on any progress NASA officials have made following the report’s release last September, but as of the time of publication, it had not yet received a response.

“The top takeaway from the study is that there is a lot more to learn,” NASA Administrator Bill Nelson said following the report’s release. “We will use NASA’s expertise to work with other agencies to analyze UAP,” Nelson added, stressing the importance of shifting the UAP dialogue from sensationalism to science and sharing findings globally.

Nelson also said that his agency will remain committed to transparency on the issue and to attempting to better understand what UAP might represent.

“We are open, and we’re going to be open about this,” Nelson also said in response to a question from filmmaker James Fox, who attended last September’s press conference.

“We don’t know what these UAP are,” Nelson said, “but we’re gonna try to find out.”

However, in contrast to Nelson’s statements at the time, NASA has remained mostly silent on the UAP issue since the report’s release last year, providing few indications publicly that it plans to maintain any degree of active engagement with the matter, a reality that appeared to be reflected in the limited guidance agency officials and former members of NASA’s UAP study team were willing to provide in response to The Debrief’s inquiries over the last several weeks.

Following the publication of the UAPIST report last year, a short article published by Boston University’s Photonics Center quoted Joshua Semeter, a professor with the school’s Department of Electrical and Computer Engineering and a member of NASA’s UAP study team who was appointed to the group for his specialization in imaging and remote sensing observations.

“Even Professor Semeter was surprised to find the report focused more on mapping out next steps,” the article said of Semeter, who called UAP “a strangely polarizing topic.”

“One way to think about it is that whenever you’re faced with incomplete data, your brain fills in the rest, that’s our tendency,” Semeter was quoted saying of people’s tendency to exhibit biases regarding UAP, even when it involves academics studying the phenomenon. “The tendency of people looking into UAP is to fall on one side or the other with respect to an incomplete picture,” he added.

The Debrief reached out to Professor Semeter for further comment, but like with other study team members we contacted, received no response to our requests.

Earlier this year, astrophysicist David Spergel, President of the Simons Foundation and chair of NASA’s UAP study team, also spoke briefly about the group’s assessment during a NASA Future In-Space Operations seminar that was streamed on February 7, 2024.

Weeks later, in a document published online detailing the proceedings of the NASA Advisory Council Science Committee Spring Meeting on March 25, 2024, details outlining an earlier NASA Earth Science Advisory Committee (ESAC) meeting included a summary of the UAP report’s findings, given that UAPIST was a subcommittee formed under the ESAC.

“The ESAC finds that the UAPIST Subcommittee has addressed the questions outlined in the Statement of Task, and thereby has met its Terms of Reference,” the summary states. “The ESAC finds that the scope of the Subcommittee report, including any recommendations, is beyond NASA’s Earth Science program.”

A brief ESAC Procedural Recommendation also states that “The ESAC does not have the expertise to make detailed recommendations to ESD regarding the report,” concluding that “The ESAC accordingly recommends that the report be conveyed to agency leadership.”

No additional information has currently been made available by NASA regarding any data collection plan the agency may have implemented, nor any research methods, systems integration, budget appropriation, staffing, or other efforts being undertaken by NASA’s current Director of UAP Research. Further specific requests for updates on all these issues by The Debrief remained unanswered in our communications with NASA officials.

NASA’s lack of communication on the UAP subject following the release of last year’s report leaves more questions than answers about the agency’s current stance on the issue, as well as what plans, if any, it may have in terms of ongoing engagement and coordination with other federal agencies.

While the UAP Independent Study Team concluded its report last year by emphasizing there is currently no evidence credibly linking UAP sightings to extraterrestrial technologies, the authors nonetheless conceded that such possibilities at least remain on the table.

“At this point there is no reason to conclude that existing UAP reports have an extraterrestrial source. However, if we acknowledge that as one possibility, then those objects must have traveled through our solar system to get here,” the report’s authors wrote.

“Just as the galaxy does not stop at the outskirts of the solar system, the solar system also includes Earth and its environs. Thus, there is an intellectual continuum between extrasolar technosignatures, solar system SETI, and potential unknown alien technology operating in Earth’s atmosphere.”

“If we recognize the plausibility of any of these,” the authors concluded, “then we should recognize that all are at least plausible.”
