AMAZING UFO VIDEO! UAP drops two objects over Picket Post Mountain in Arizona
AMAZING UFO VIDEO! UAP drops two objects over Picket Post Mountain in Arizona
On January 22, 2023 at 2:47 PM, a group of hikers were on their way to Picket Post Mountain in Arizona when they noticed an unusual object in the sky. The hikers, who were identified as a sister, father, and the person who reported the sighting, observed the object for about 15 seconds before recording a video of the event. The footage, which was provided to the reporter, shows a small, bright dot in the sky that appears to be stationary at first. The object then drops two “flare-like” objects and then suddenly accelerates at a high speed before disappearing from sight.
The witnesses were unable to identify the object and speculated that it could have been a high-end drone or a helicopter. However, they were convinced that the object’s sudden acceleration was not something that could be explained by any known aircraft. The witnesses were also puzzled by the “flare-like” objects that were dropped by the object, as they were unable to explain what they were.
The sighting took place in an area known for its military and airforce bases, leading some to believe that the object could have been a classified military drone. However, the witnesses’ descriptions and the footage of the object do not match any known military aircraft.
UFO sightings are not uncommon, but the sudden acceleration and the “flare-like” objects dropped by the object in this particular sighting make it unique and intriguing. The stabilized footage provided by the witnesses offers a clear view of the object, but it remains unidentified. The witnesses have expressed their desire to know more about what they saw and have asked anyone with knowledge of the object to come forward with information.
Bellow you can watch original and stabilized footage from this latest UFO sighting!
Ex-Area 51 Sentry Reveals Shocking Details of Disc-Shaped Craft and Alien Beings at Top-Secret Facility
Ex-Area 51 Sentry Reveals Shocking Details of Disc-Shaped Craft and Alien Beings at Top-Secret Facility
In a this video interview, former S-4 Level 2 sentry Derek Hennesy, also known as Connor O’Ryan, revealed his experiences of witnessing grey extraterrestrial beings and disc-shaped craft at Area 51. Hennesy explained that there are four levels in S-4, with the top level being a hanger for the flying disc ships. He stated that the first and second levels are all elevator where they keep the flying disc ships, and that while he was there, they were trying to operate the disc, which he witnessed unsuccessfully. He also mentioned that there were scientists and high-level White House officials present at the facility.
Hennesy described the layout of the facility, including four elevators and the fact that there are no centuries on levels three and four. He stated that he had no knowledge of what goes on in those levels, but he had heard rumors of a heavy or EB being present. He also described the bays on level two, which are separated by automatic doors and contain elevators that can bring the whole floor to the top.
The most striking revelation from Hennesy was his description of the storage of extraterrestrial bodies on level two. He stated that there were tubes present, about two feet in width and six feet in height, and that the creatures inside were completely identical, with no way of identifying them individually. He described the creatures as resembling the typical depiction of grey aliens, but with shriveled eyes that resembled prunes and no visible eyelids or hair. He also stated that their bodies were very thin and frail-looking.
Hennesy also described the security measures in place at the facility, including a plastic card with magnetic information, a handprint scan, and a right eye retina scan for access to levels three and four. He stated that if clearance was not granted, instructions were to arrest the individual immediately.
Hennesy’s testimony has been deemed credible by those who conducted the interview, as his voice analysis did not show any signs of stress, and the information he provided matched up with other information and rumors that have been circulating about the secretive Area 51 facility.
SpaceX launches 'heaviest' Starlink batch yet, nails landing
A SpaceX Falcon 9 rocket launched its heaviest payload to date, carrying 56 Starlink satellites that weighed in at a combined 17.4 metric tonnes (19.4 tons). The rocket lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida on Jan. 26, 2023.
Disaster! China can't STOP COPYING SpaceX Rockets, making laugh to Elon...
If imitation is the sincerest form of flattery, Elon Musk's SpaceX must be very pleased with the Chinese space program. CAS-SPACE had an opening ceremony of their manufacturing base in Nansha, Guangzhou on JAN.09. And this is their new crew capsule presented. If you think have you deja vu while looking at this image, you’re not wrong. The new Chinese spacecraft resembles another spacecraft that has carried astronauts into space for three years. That’s right; it looks similar to SpaceX’s Dragon capsule. To wit, China seems Cloned SpaceX Dragon! And with this being said, what could be the reaction of SpaceX CEO Elon Musk?
Find out everything about this in today's episode of Alpha Tech:
CAS Space, a commercial spinoff from the Chinese Academy of Sciences (CAS), is already developing rockets for commercial satellite launches and announced in 2021 that it wants to send people up into space, albeit briefly.
According to the press release, CAS Space is working on a single-stage reusable rocket that would take as many as seven passengers on a 10-minute ride up above the Kármán line at 62 miles (100 kilometers), which is generally held to be the boundary between Earth's atmosphere and outer space. Its name ZK6, high 15m; Diameter: 3.35m with 4 windows; ZK6 is powered by 5 15t XY1 engines; It can reuse more than 30 times.
All of us can see that the ZK6 remarkably resembles SpaceX's Crew Dragon capsule, right? In addition, ZK6 also has grid fins near the top of the rocket, which would guide the rocket’s descent. And instead of landing legs, the rocket would be "caught" by an arm attached to the launch tower, following a concept unveiled by SpaceX for its massive Starship Super Heavy rocket. The crew capsule will meanwhile descend to Earth with the aid of three parachutes. Disaster! China can't STOP COPYING SpaceX Rockets, making laugh to Elon...

The Parker Solar Probe created history by becoming the first spacecraft to touch the Sun. It passed through the Sun’s upper atmosphere, known as the corona. Temperatures in the solar corona can soar up to a million degrees Celsius. It’s the hottest region of the solar atmosphere and is about 15 times hotter than the surface of the Sun.
But the critical question is, why didn’t the Parker Solar Probe melt when it touched the Sun? No metal can withstand such high temperatures. So how did Parker manage to survive after plunging into the solar atmosphere? How is it still functioning efficiently after going through such an extreme environment?
The answer is a combination of the physics of the solar corona and the marvelous engineering of Parker.

Which Planet Is Easier To Terraform Mars Or Venus?
Mars and Venus are Earth's two twins, or not? Venus is a hot where sulfuric acid rains and temperatures melt lead; in contrast, Mars is a cold desert where temperatures can drop to -200°F (-129°C)). Both worlds are extremely opposite, but... If humanity wanted to move to either of the two in the future, which would be easier to terraform? Are both planets equally optimal for becoming green and blue worlds like Earth? Let's find out! Terraforming This is a hypothetical process aimed at deliberately modifying the atmosphere, temperature, topography, or ecology of a planet or natural satellite to resemble the Earth's environment and make it suitable to host living beings. The term terraforming itself was first used in 1982, when planetologist Christopher McKay wrote Terraforming Mars, an article for the British Interplanetary Society in which he proposed a method for heating the atmosphere of Mars. Venus's atmosphere is so dense that its pressure would cru ars, by contrast, is an icy planet that lost most of its atmosphere, lacking oxygen to breathe. None of our neighbors within the solar system are incredibly hospitable to living things. However, on the last mission to Mars, the Perseverance rover managed to convert carbon dioxide (CO2) from the Martian atmosphere into a small amount of oxygen for an astronaut to breathe. This could be the first step, somewhat modest, but hope for future terraforming of the red planet. For his part, the famous astronomer and science popularizer Carl Sagan, known for the television series Cosmos, proposed the application of planetary engineering on Venus to make it habitable in an article published in the journal Science in 1961. They planned to seed the atmosphere of the fiery planet with algae, which would be responsible for quickly consuming CO2 from the atmosphere, thus reducing the planet's greenhouse effect and making it friendlier to other forms of life. It seems that both Mars and Venus are excellent candidates to be terraformed, but what process would we use to achieve this?

Scientists Find Ancient Scroll That Reveals Something Huge Happened During The Reign Of This Pharaoh
The Floating Combat Remote Dropped from Space
The United States government established the Strategic Defense Initiative Organization during the late stages of the Cold War. Created to render intercontinental atomic warfare obsolete amidst the rising nuclear tensions, the organization sought to create a protective shield that negated an enemy's first-strike advantage.
While the organization was active, several revolutionary concepts were studied, including Brilliant Pebbles.
Conceived as part of a pre-existing concept, the Brilliant Pebbles were small, maneuverable, rocket-powered, laser-equipped vehicle systems that were able to detect, track, and intercept enemy ballistic missiles when placed in orbit.
The idea was to send thousands of pebbles to circle the planet, ready to make an appearance at a moment’s notice. When necessary, the tiny missile interceptors would destroy their prey by smashing into them.
Most experts believed the project was too good to be true, but it soon became the main focus of the entire organization responsible for developing strategic defenses. Not even budget cuts would prevent the Brilliant Pebbles from beginning trials in 1990 and proving everyone wrong…
The Ship That Flew: USS Plainview
In the late 1950’s a new threat emerged from the Soviet Union for which the Americans were seemingly caught off guard. The latest generation of Soviet nuclear-powered submarines could reach incredible speeds. The Alfa-Class submarine under development at the time would eventually be capable of travelling at 41 knots (76 kph/47 mph) while fully submerged. At such speeds, these submarines could follow American fleets while easily evading ASW ships. Large, fast, ocean-going hydrofoils seemed like the answer.
The principle behind a hydrofoil was simple enough; by using water as a medium of flight, much like an airplane uses air, a hydrofoil could ‘fly’ rather than plow through water. Using a set of underwater wing-like structures called foils, these ships could lift out of the water as they accelerated, significantly reducing drag and allowing for much higher speeds and efficiency.
The first practical hydrofoil was demonstrated in 1906 by Italian inventor Enrico Forlanini. In the decades that followed, hydrofoils were progressively refined and in the 1950’s the first passenger hydrofoils were beginning to emerge on rivers and lakes. Almost all of these early hydrofoils used a configuration commonly referred to as ‘surface-piercing’ where the foils operate along the surface of the water. The configuration is dynamically stable and self-correcting as a result of the foil’s shape (typically curved) and the position of the center of gravity in relation to the foil. A major drawback is that operation along the water’s surface makes surface-piercing hydrofoils easily disturbed by waves and rough conditions. Surface-piercing hydrofoils are generally considered unsuitable for open ocean travel.
In the 1950’s the U.S. Navy took significant interest in a second hydrofoil configuration commonly referred to as ‘fully submerged’. Unlike surface-piercing hydrofoils, fully submerged hydrofoils have foils that operate entirely underwater beneath waves. This makes them far more suitable in rough conditions and open water. A major drawback is that they are not dynamically stable and require continual adjustments to the foil angle of attack to vary the lift generated. For decades an automated method of controlling the foils remained elusive.
With new emerging technologies in the 1950's and 1960's, like sophisticated sensors, autopilots and computers, the fully submerged hydrofoil configuration became far more practical. The U.S. Navy saw them as a potentially ground-breaking solution, ideally suited for ASW. Research and development efforts would culminate in a series of prototype ships, the most impressive being the 320-ton USS Plainview.
NASA revealed Tuesday it is building a nuclear-powered rocket that could send humans to Marsmuch faster than the traditional craft - it currently takes seven months to reach the Red Planet.
The American space agency partnered with the Defense Advanced Research Projects Agency (DARPA) on the Demonstration Rocket for Agile Cislunar Operations (DRACO) program that will be tested in 2027.
A nuclear thermal rocket (NTR) offers a high thrust-to-weight ratio of around 10,000 times greater than electric propulsion and two-to-five times greater efficiency than in-space chemical propulsion.
The team plans to use previous NTR models to design DRACO, while providing it with a modern touch - the last technology tested on the ground was more than 50 years ago.
NASA and DARPA are working on a nuclear rocket that could take humans to Mars much faster - dramatically reducing the current seven-month journey
The space agency has studied the concept of nuclear thermal propulsion for decades.
This technology introduces heat from a nuclear fission reactor to a hydrogen propellant to provide a thrust believed to be far more efficient than traditional chemical-based rocket engines.
Along with faster transit, the groups said NTR would reduce the risk for astronauts because they will not be traveling through space as long.
That would substantially reduce the time astronauts would be exposed to deep-space radiation and require fewer supplies, such as food and other cargo, during a trip to Mars.
NASA is eyeing the late 2030s for when it will send humans to the Martian world.
'If we have swifter trips for humans, they are safer trips,' NASA deputy administrator and former astronaut Pam Melroy said Tuesday.
NTR transfers heat from the reactor directly to a gaseous hydrogen propellant.
Heated hydrogen expands through a nozzle to provide thrust to propel a spacecraft.
And materials inside the fission reactor must be able to survive temperatures above 4,600 degrees Fahrenheit.
NASA has had NTR on its radar for more than 60 years and first embarked on the mission in 1961.
This led the then-NASA Marshall Space Flight Center director and rocket pioneer, Wernher von Braun, to advocate for a proposed mission, dispatching a dozen crew members to Mars aboard two rockets.
Each rocket would be propelled by three Nuclear Engine for Rocket Vehicle Application (NERVA) engines - designs drafted in 1961.
As detailed by von Braun, that expeditionary crew would launch to the Red Planet in November 1981 and land on that distant world in August 1982.
In presenting his visionary plan in August 1969 to a Space Task Group, von Braun explained that 'although the undertaking of this mission will be a great national challenge, it represents no greater challenge than the commitment made in 1961 to land a man on the moon.'
However, this vision of human boots on Mars ended in 1972 when priorities shifted and space budgets were cut.
A nuclear-powered rocket would substantially reduce the time astronauts would be exposed to deep-space radiation and require fewer supplies, such as food and other cargo, during a trip to Mars
Fast forward to the present, and NASA is back on the path to the Red Planet and has enlisted help from the US government to make it happen.
Dr Stefanie Tompkins, director at DARPA, said in a statement: 'DARPA and NASA have a long history of fruitful collaboration in advancing technologies for our respective goals, from the Saturn V rocket that took humans to the Moon for the first time to robotic servicing and refueling of satellites.
'The space domain is critical to modern commerce, scientific discovery, and national security.
'The ability to accomplish leap-ahead advances in space technology through the DRACO nuclear thermal rocket program will be essential for more efficiently and quickly transporting material to the Moon and eventually, people to Mars.'
NASA test nucleaire raketten die astronauten in recordtijd naar Mars kunnen vliegen
Staan er binnen enkele jaren astronauten op Mars? NASA heeft alvast aangekondigd dat ze raketten, aangedreven met kernenergie, gaan testen die mensen tot mars kunnen vervoeren. Het agentschap werkt samen met het Amerikaanse Defense Advanced Research Projects Agency (Darpa) om al in 2027 een nucleaire thermische raketmotor in de ruimte te sturen. Dat staat te lezen in de Britse krant The Guardian.
KIJK. NASA wil raket met kernaandrijving ontwikkelen
NASA
NASA wil een baanbrekend voortstuwingssysteem ontwikkelen dat sterk verschilt van de chemische systemen die gangbaar zijn sinds het moderne rakettijdperk bijna een eeuw geleden begon. “Het gebruik van een nucleaire thermische raket maakt een snellere transittijd mogelijk, waardoor het risico voor astronauten afneemt”, aldus NASA in een persbericht.
“Het verkorten van de reistijd is een belangrijke component voor menselijke missies naar Mars, aangezien langere reizen meer voorraden en robuustere systemen vereisen.” Een bijkomend voordeel is een grotere capaciteit van de wetenschappelijke lading en een groter vermogen voor instrumenten en communicatie, aldus het agentschap.
Recordsnelheid
NASA, dat vorig jaar met succes zijn nieuwe Artemis-ruimtevaartuig heeft getest als springplank naar de maan en Mars, hoopt ergens in de jaren 2030 mensen op de rode planeet te laten landen. Met de huidige technologie zou de reis naar Mars ongeveer zeven maanden duren. Ingenieurs weten nog niet hoeveel tijd er met nucleaire technologie kan worden bespaard, maar Bill Nelson, de beheerder van de NASA, meldde aan The Guardian dat ruimtetuigen en mensen dan met een recordsnelheid door de diepe ruimte kunnen reizen.
Nucleaire elektrische voortstuwingssystemen maken veel efficiënter gebruik van drijfgassen dan chemische raketten, maar leveren weinig stuwkracht, aldus het agentschap. Door efficiënt gebruik te maken van lage stuwkracht, versnellen nucleaire elektrische voortstuwingssystemen ruimtevaartuigen gedurende langere perioden en kunnen zij een Marsmissie voortstuwen voor een fractie van de stuwstof van systemen met hoge stuwkracht.
Stefanie Tompkins, de directeur van Darpa, zei dat de overeenkomst een uitbreiding is van de bestaande samenwerking tussen de agentschappen. “Darpa en NASA hebben een lange geschiedenis van vruchtbare samenwerking bij het bevorderen van technologieën voor onze respectieve doelen, van de Saturnus V-raket die mensen voor het eerst naar de maan bracht tot het robotiseren en bijtanken van satellieten.
“De ruimte is van cruciaal belang voor de moderne handel, wetenschappelijke ontdekkingen en nationale veiligheid. Het vermogen om met sprongen vooruit te gaan in de ruimtetechnologie zal essentieel zijn om efficiënter en sneller materiaal naar de maan en uiteindelijk mensen naar Mars te vervoeren”, zegt Tompkins in een verklaring.
Maanlanding
Nasa’s Artemis 2-missie, die voor het eerst in meer dan een halve eeuw mensen rond de maan zal sturen, staat gepland voor 2024. De daaropvolgende Artemis 3-missie, die het jaar daarop zou kunnen komen, zal voor het eerst sinds 1972 astronauten, waaronder de eerste vrouw, op het maanoppervlak laten landen.

Amazing UFO sighting video from Zambia, 2023!
Latest UFO sighting of 4 bright objects hovering in formation.
On January 20, 2023, a UFO sighting was reported in Lusaka, Zambia. The sighting was captured on video by a witness who was visibly amazed and confused by what he was seeing. In the video, the witness can be heard asking for a scientific explanation for the strange phenomenon he was witnessing. He also expressed frustration at the lack of interest and understanding from others in the community.
The witness observed four huge bright unknown objects in perfect alignment, which he found to be unusual and unexplained. He questioned the scientific community to provide an explanation for what he was seeing, and expressed disbelief at the alignment of the stars. He also urged others to open their eyes and pay attention to what is happening in the world around them, rather than focusing solely on material pursuits.
This is the first UFO sighting from Zambia that we have posted on Latest-UFO-Sightings.net website since we started this website in 2009. As the website dedicated to UFO sightings, we are always searching for credible and verifiable information from all over the world that can help shed light on this fascinating topic. We will continue to monitor this case and any new developments from Zambia and encourage anyone with information or evidence to come forward.
“Residents of Bethany Beach, Delaware were surprised by a UFO sighting on January 24th, 2023. The objects were described as “super bright” with “slow, alternating flashing” pattern. Is it related to NASA’s Wallops Island launch or something extraterrestrial?
Residents of Bethany Beach, Delaware were in for a surprise on the evening of January 24th, 2023 when a UFO sighting was reported. The incident occurred around 8:35-8:40pm, when a local resident stepped out on their porch and saw several strange objects in the sky.
According to the witness, the objects were “super bright” and had a “slow, alternating flashing” pattern. They were also distinct from a plane that was seen in the vicinity, leading the witness to believe that they were not of terrestrial origin. The witness also mentioned that this was not the first time strange UFO sightings have been reported in the area.
The sighting could be related to the recent NASA launch from Wallops Island, however, no official statement has been made to confirm or deny this theory. The distance to Wallops Island – NASA’s Launch Pad 0-A is around 50 mi (80 km).

How SpaceX Crew Dragon DESTROYED Soyuz and Starliner?
How SpaceX Crew Dragon DESTROYED Soyuz and Starliner? Nearly a decade ago, the business of space changed. Exactly in 2014, NASA tapped SpaceX and Boeing to build two new human-rated spacecraft, the Crew Dragon and Starliner, respectively. this was intended to end dependence on Russia's Soyuz. Each company would first prove its ship capable of safe flight, then perform as many as six crewed missions to the International Space Station. From that moment onward, Soyuz, Boeing Starliner, and Crew Dragon capsules have been put on the scale together. The result? SpaceX Crew Dragon completely destroy the others. You ask me why? Let’s explain:
We can't deny that so far, the International Space Station is still one of the greatest engineering feats humans have designed due to its support for almost every space mission that leaves earth. It is one of a kind for it is one of the few times humanity has come together to build and use an item or station without any fracas. Since it was launched, hundreds of laboratory researches that have led to understanding space and how humans may survive on other planets have been done.
After all, it’s a football field sized floating laboratory traveling 10 times faster than a bullet, circling the Earth every 90 minutes. It’s taken 33 launches to put all of its pieces into orbit and has been home in space to astronauts from almost 20 countries.
The ISS typically has 6 astronauts onboard. Crews are sent in groups of 3 and usually reside at the station for 6 months. There is typically a 3-month overlap for the existing crew and the newly arriving crew. Since the Space Shuttle program ended in 2011, there’s only been a single ride to the ISS. Russia’s Soyuz vehicle.
Since NASA ended its space-shuttle program in 2011, the agency has relied exclusively on Russia to ferry its astronauts to and from orbit in Soyuz spacecraft. But those seats have gotten increasingly expensive, and the world's space agencies have had no alternative for launching and returning astronauts, even when technical glitches have arisen.

New Discovery That Changed Physics! Gravity Is Not a Force!
In his 1915 General Theory of Relativity, Albert Einstein defined gravity as the bending of space and time. This was the prevailing idea of gravity for the following century. But now, a new theory has been proposed that could change everything we know about gravity. The Digital Gravity Theory proposes that gravity is not a force but rather the product of the topology of space and time. If this new theory is correct, it could mean a complete overhaul of our understanding of physics. So far, it has been met with a lot of skepticism, but the scientists who proposed it are convinced that it is the right answer. Watch, like and comment on New Discovery That Changed Physics! Gravity Is Not a Force!What do you think? Is this new theory correct, or is it just another crackpot idea?

Het duo is te zien op deze fascinerende ruimtefoto van de week.
Het duo – Arp-Madore 417-391 – is aan de rechterkant te zien. De twee sterrenstelsels zijn 670 miljoen lichtjaar van de aarde verwijderd. Zoals je ziet zijn de sterrenstelsels vervormd door zwaartekracht, waardoor ze nu een soort ring vormen. De twee heldere kernen van het duo liggen inmiddels naast elkaar en zullen over niet al te lange tijd samensmelten en één kern vormen.
De Arp-Madore-catalogus bestaat uit circa 6.000 ongebruikelijke sterrenstelsels, gefotografeerd door de Australische UK Schmidt-telescoop. De catalogus is samengesteld door astronomen Barry Madore en Halton Arp. Hubble fotografeert wel vaker bijzondere Arp-Madore-objecten, zoals Arp-Madore 2026-424 in 2019.

The otherwise unremarkable double asteroid of Didymos and Dimorphos made headlines as the target of NASA’s successful Double Asteroid Redirect Test (DART) mission. With new details about the system emerging, astronomers have put together a hypothesis of how this strange double asteroid came to be.
It starts with spin. Any solid body if it spins fast enough will lose pieces of itself as the centrifugal force overwhelms gravity. This is especially true of asteroids, which aren’t very big to begin with and are only loosely held together. Recently a team of astronomers have used this fact to propose a plausible formation mechanism for Didymos and Dimorphos.
In this scenario long ago Didymos spun up far too quickly. It could have been from a glancing collision or just from too many gravitational interactions with neighbors. Once it spun up it began losing mass, which formed a ring surrounding it. Initially this ring would be in what is called the Roche limit of the asteroid. The Roche limit is where the gravitational tidal force from a parent body is stronger than the ability for material orbiting it to hold itself together. So within the Roche limit Dimorphos couldn’t form .
But through many interactions some of the material can migrate away from the ring and go beyond the Roche limit where it would eventually coalesce. That material that escaped would eventually become the little moon Dimorphos.
The astronomers estimate that Didymos had to lose at least 25% of its mass in order to form Dimorphos in this manner. This model also predicts that Dimorphos will have a very irregular shape because it was built up from the slow accumulation of many smaller objects, which is in line with what we observe.
While NASA’s DART mission was an overall success, showing that we can conclusively nudge the orbit of an asteroid if we need to, the mission has another side benefit. It helps us explore the complicated, intricate lives of some of the smallest, and most often ignored, objects in the solar system.
Earth’s inner core is made mostly of solid iron, and can rotate separately from the outer parts of the planet.

Thousands of kilometres beneath your feet, Earth’s interior might be doing something very weird. Many scientists think that the inner core spins faster than the rest of the planet — but sometime in the past decade, according to a study, it apparently stopped doing so.
“We were quite surprised,” say Yi Yang and Xiaodong Song, seismologists at Peking University in Beijing who reported the findings today in Nature Geoscience1.
The results could help to shine light on the many mysteries of the deep Earth, including what part the inner core plays in maintaining the planet’s magnetic field and in affecting the speed of the whole planet’s rotation — and thus the length of a day. But they are just the latest instalment in a long-running effort to explain the inner core’s unusual rotation, and might not be the final word on the matter.
“I keep thinking we’re on the verge of figuring this out,” says John Vidale, a seismologist at the University of Southern California in Los Angeles. “But I’m not sure.”
Mysteries of the deep
Researchers discovered the inner core in 1936, after studying how seismic waves from earthquakes travel through the planet. Changes in the speed of the waves revealed that the planet’s core, which is about 7,000 kilometres wide, consists of a solid centre, made mostly of iron, inside a shell of liquid iron and other elements. As iron from the outer core crystallizes on the surface of the inner core, it changes the density of the outer liquid, driving churning motions that maintain Earth’s magnetic field.
Researchers have learnt about the inner core’s rotation by studying earthquakes that originated in the same region, such as the Kuril Islands (shown here), over decades.

The liquid outer core essentially decouples the 2,400-kilometre-wide inner core from the rest of the planet, so the inner core can spin at its own pace. In 1996, Song and another researcher reported2 studying earthquakes that originated in the same region over three decades, and whose energy was detected by the same monitoring station thousands of kilometres away. Since the 1960s, the scientists said, the travel time of seismic waves emanating from those earthquakes had changed, indicating that the inner core rotates faster than the planet’s mantle, the layer just beyond the outer core.
Later studies refined estimates of the rate of that ‘super-rotation’, to conclude that the inner core rotates faster than the mantle by about one-tenth of a degree per year. But not everyone agrees. Other work has suggested that super-rotation happens mostly in distinct periods, such as in the early 2000s, rather than being a continuous, steady phenomenon3. Some scientists even argue that super-rotation does not exist, and that the differences in earthquake travel times are instead caused by physical changes on the surface of the inner core4.
Last June, Vidale and Wei Wang, an Earth scientist also at the University of Southern California, threw another spanner into the works. Using data on seismic waves generated by US nuclear test blasts in 1969 and 1971, they reported that between those years, Earth’s inner core had ‘subrotated’, or rotated more slowly than the mantle5. Only after 1971, they say, did it speed up and begin to super-rotate.
A rotational shift
Now, Yang and Song say that the inner core has halted its spin relative to the mantle. They studied earthquakes mostly from between 1995 and 2021, and found that the inner core’s super-rotation had stopped around 2009. They observed the change at various points around the globe, which the researchers say confirms it is a true planet-wide phenomenon related to core rotation, and not just a local change on the inner core’s surface.
The data hint that the inner core might even be in the process of shifting back towards subrotation. If so, something is probably happening to the magnetic and gravitational forces that drive the inner core’s rotation. Such changes might link the inner core to broader geophysical phenomena such as increases or decreases in the length of a day on Earth.
Still, many questions remain, such as how to reconcile the slow pace of the changes that Yang and Song report with some of the faster changes reported by others. The only way out of the morass is to wait for more earthquakes to happen. A “long history of continuous recording of seismic data is critical for monitoring the motion of the heart of the planet”, say Yang and Song.
“We just have to wait,” Vidale adds.

In the 1970s, astronomers discovered that the persistent radio source at the center of our galaxy was a supermassive black hole (SMBH). Today, this gravitational behemoth is known as Sagittarius A* and has a mass roughly 4 million times that of the Sun. Since then, surveys have shown that SMBHs reside at the center of most massive galaxies and play a vital role in star formation and galactic evolution. In addition, the way these black holes consume gas and dust causes their respective galaxies to emit a tremendous amount of radiation from their Galactic Centers.
These are what astronomers refer to as Active Galactic Nuclei (AGN), or quasars, which can become so bright that they temporarily outshine all the stars in their disks. In fact, AGNs are the most powerful compact steady sources of energy in the Universe, which is why astronomers are always trying to get a closer look at them. For instance, a new study led by the University of California, Santa Cruz (UCSC) indicates that scientists have substantially underestimated the amount of energy emitted by AGN by not recognizing the extent to which their light is dimmed by dust.

The research was led by Dr. Martin Gaskell, a research associate and lecturer at UCSC’s Department of Astronomy and Astrophysics. He was joined by a team of engineers, mathematicians, astronomers, and astrophysicists from Harvey Mudd College, Princeton University, and the University of California Berkeley. For their study, the team examined NGC 5548, a Type I Seyfert galaxy located about 244.6 million light-years away. This galaxy has a bright AGN, resulting from a central SMBH of roughly 65 million Solar masses.
The amount of dust is measured by the way it causes light from the AGN to shift toward the red end of the spectrum. This effect is known as “reddening,” and the amount of reddening corresponds directly to the amount of dimming. Although scientists have long recognized the possibility that dust dims the light from AGNs, the amount was widely considered negligible. The issue stemmed from the fact that astronomers predicted the amount of reddening based on theories regarding the intrinsic, unreddened colors astronomers should be seeing.
According to the results from this latest research, the amount of obscuring dust may be underestimated, much like the overall brightness of AGNs. The team reached this conclusion by studying the reddening effect of dust in the most well-studied AGN (NGC 5548) using seven different indicators. These included a mean AGN reddening curve, a standard reddening curve of the Milky Way, and the Small Magellanic Cloud (SMC) curve. In all cases, they found that the reddening of NGC 5548 was about 14 times greater than what is observed in the solar neighborhood due to the small amount of dust.
As Dr. Gaskell explained in a Royal Astronomical Society press release:
“When there are intervening small particles along our line of sight, this makes things behind them look dimmer. We see this at sunset on any clear day when the sun looks fainter. The good agreement between the different indicators of the amount of reddening was a pleasant surprise. It strongly supports simple theories of emission from active galactic nuclei. Exotic explanations of colors are not needed. This makes life simpler for researchers and is speeding up our understanding of what happens as black holes swallow material.”

These results show that In the ultraviolet wavelength, where most of their energy is radiated, a typical AGN puts out an order of magnitude more energy than previously thought. Another takeaway is that AGNs are very similar, and what was thought to be fundamental differences in brightness and energy output are actually the result of different amounts of dust. This could have drastic implications for our understanding of galactic formation, evolution, and the role played by SMBHs in both.
A Novel Propulsion System Would Hurl Hypervelocity Pellets at a Spacecraft to Speed it up
Today, multiple space agencies are investigating cutting-edge propulsion ideas that will allow for rapid transits to other bodies in the Solar System. These include NASA’s Nuclear-Thermal or Nuclear-Electric Propulsion (NTP/NEP) concepts that could enable transit times to Mars in 100 days (or even 45) and a nuclear-powered Chinese spacecraft that could explore Neptune and its largest moon, Triton. While these and other ideas could allow for interplanetary exploration, getting beyond the Solar System presents some major challenges.
As we explored in a previous article, it would take spacecraft using conventional propulsion anywhere from 19,000 to 81,000 years to reach even the nearest star, Proxima Centauri (4.25 light-years from Earth). To this end, engineers have been researching proposals for uncrewed spacecraft that rely on beams of directed energy (lasers) to accelerate light sails to a fraction of the speed of light. A new idea proposed by researchers from UCLA envisions a twist on the beam-sail idea: a pellet-beam concept that could accelerate a 1-ton spacecraft to the edge of the Solar System in less than 20 years.
The concept, titled “Pellet-Beam Propulsion for Breakthrough Space Exploration,” was proposed by Artur Davoyan, an Assistant Professor of Mechanical and Aerospace Engineering at the University of California, Los Angeles (UCLA). The proposal was one of fourteen proposals chosen by the NASA Innovative Advanced Concepts (NIAC) program as part of their 2023 selections, which awarded a total of $175,000 in grants to develop the technologies further. Davoyan’s proposal builds on recent work with directed-energy propulsion (DEP) and light sail technology to realize a Solar Gravitational Lens.

As Prof. Davoyan told Universe Today via email, the problem with spacecraft is that they are still beholden to the Rocket Equation:
“All current spacecraft and rockets fly by expanding fuel. The faster the fuel is thrown away, the more efficient is the rocket. However, there is a limited amount fuel that we can carried on board. As a result, the velocity a spacecraft can be accelerated to is limited. This fundamental limit is dictated by the Rocket Equation. The limitations of Rocket Equation translate into a relatively slow and costly space exploration. Such missions as Solar Gravitational Lens are not feasible with current spacecraft.”
The Solar Gravitational Lens (SGL) is a revolutionary proposal that would be the most powerful telescope ever conceived. Examples include the Solar Gravity Lens, which was selected in 2020 for NIAC Phase III development. The concept relies on a phenomenon predicted by Einstein’s Theory of General Relativity known as Gravitational Lensing, where massive objects alter the curvature of spacetime, amplifying the light from objects in the background. This technique allows astronomers to study distant objects with greater resolution and precision.
By positioning a spacecraft at the heliopause (~500 AU from the Sun), astronomers could study exoplanets and distant objects with the resolution of a primary mirror measuring around 100 km (62 mi) in diameter. The challenge is developing a propulsion system that could get the spacecraft to this distance in a reasonable amount of time. To date, the only spacecraft to reach interstellar space have been the Voyager 1 and 2 probes, which launched in 1977 and are currently about 159 and 132 AUs from the Sun (respectively).
When it left the Solar System, the Voyager 1 probe was traveling at a record-breaking velocity of about 17 km/s (38,028 mph), or 3.6 AU a year. Nevertheless, this probe still took 35 years to reach the boundary between the Sun’s solar wind and the interstellar medium (the heliopause). At its current speed, it will take over 40,000 years for Voyager 1 to fly past another star system – AC+79 3888, an obscure star in the constellation Ursa Minor. For this reason, scientists are investigating directed energy (DE) propulsion to accelerate light sails, which could reach another star system in a matter of decades.

As Prof. Davoyan explained, this method offers some distinct advantages but also has its share of drawbacks:
“Laser sailing, unlike conventional spacecraft and rockets, does not require fuel on board to accelerate. Here acceleration comes from a laser pushing the spacecraft by radiation pressure. In principle, near-speed-of-light velocities can be reached with this method. However, laser beams diverge at long distances, meaning that there is only a limited distance range over which a spacecraft can be accelerated. This limitation of laser sailing leads to a need of having exorbitantly high laser powers, gigawatts, and in some proposals, terawatts, or puts a constraint on spacecraft mass.”
Examples of the laser-beam concept include Project Dragonfly, a feasibility study by the Institute for Interstellar Studies (i4is) for a mission that could reach a nearby star system within a century. Then there’s Breakthrough Starshot, which proposes a 100-gigawatt (Gw) laser array that would accelerate gram-scale nanocraft (Starchip). At a maximum velocity of 161 million km (100 million mi) or 20% of the speed of light, Starshot will be able to reach Alpha Centauri in about 20 years. Inspired by these concepts, Prof. Davoyan and his colleagues propose a novel twist on the idea: a pellet-beam concept.
This mission concept could serve as a fast-transit interstellar precursor mission, like Starshot and Dragonfly. But for their purposes, Davoyan and his team examine a pellet-beam system that would propel a ~900 kg (1 U.S. ton) payload to a distance of 500 AU in less than 20 years. Said Davoyan:
“In our case, the beam pushing the spacecraft is made of tiny pellets, hence [we call it] the pellet beam. Each pellet is accelerated to very high velocities by laser ablation, and then the pellets carry their momentum to push the spacecraft. Unlike a laser beam, pellets do not diverge as quickly, allowing us to accelerate a heavier spacecraft. The pellets, being much heavier than photons, carry more momentum and can transfer a higher force to a spacecraft.”

In addition, the small size and low mass of the pellets mean that they can be propelled by relatively low-power laser beams. Overall, Davoyan and his colleagues estimate that a 1-ton spacecraft could be accelerated to velocities of up to ~30 AU a year using a 10-megawatt (Mw) laser beam. For the Phase I effort, they will demonstrate the feasibility of the pellet-beam concept through detailed modeling of the different subsystems and proof-of-concept experiments. They will also explore the utility of the pellet-beam system for interstellar missions that could explore neighboring stars in our lifetimes.
“The pellet beam aims to transform the way deep space is explored by enabling fast transit missions to far-away destinations,” said Davoyan. “With the pellet beam, outer planets can be reached in less than a year, 100 AU in about three years, and solar gravity lens at 500 AU in about 15 years. Importantly, unlike other concepts, the pellet-beam can propel heavy spacecraft (~1 ton), which substantially increases the scope of possible missions.”
If realized, an SGL spacecraft would allow astronomers to directly image neighboring exoplanets (like Proxima b) with multipixel resolution and obtain spectra from their atmospheres. These observations would offer direct evidence of atmospheres, biosignatures, and possibly even technosignatures. In this way, the same technology that lets astronomers directly image exoplanets and study them in extensive detail would also enable interstellar missions to explore them directly.
A New Survey of the Milky Way Reveals Billions of Objects, Helping to Map Our Surroundings in Three Dimensions
This image, which is brimming with stars and dark dust clouds, is a small extract — a mere pinprick — of the full Dark Energy Camera Plane Survey (DECaPS2) of the Milky Way. The new dataset contains a staggering 3.32 billion celestial objects — arguably the largest such catalog so far.

A New Survey of the Milky Way Reveals Billions of Objects, Helping to Map Our Surroundings in Three Dimensions
The Dark Energy Camera Plane Survey 2 (DECaPS2) is out. This is the second data release from DECaPS, and the survey contains over 3 billion objects in the Milky Way. As the leading image shows, there are so many stars it appears as if there’s no space between them.
Throughout most of human history, the nature of the Milky Way has confounded us. Aristotle thought that it resulted from the ignition of Earth’s upper atmosphere, similar to how comets produce tails. The famous Persian scholar Al-Biruni thought the Milky Way was made up of countless fragments of nebulous stars. There are countless other ideas of what the Milky Way might have been.
Our modern understanding of the Milky Way is exquisitely detailed. Large-scale surveys of the galaxy have played a huge role in our growing understanding of the Milky Way. The ESA’s Gaia mission, an ongoing survey of the Milky Way, has collected detailed data on over one billion stars, including their ages, masses, chemical compositions, colours, temperatures, and metal content.
Will DECaPS2 make a similar contribution? It might, based on raw data alone.
“When combined with images from Pan-STARRS 1, DECaPS2 completes a 360-degree panoramic view of the Milky Way’s disk…”
Edward Schlafly, paper co-author, Space Telescope Science Institute.
DECaPS2 contains 3.32 billion objects built from 34 billion detections. The detections are in 21,400 exposures which added up to 260 hours of open shutter time with the Dark Energy Camera (DECam) at the Cerro Tololo observatory. Of the 3.32 billion objects, about 2 billion are stars. It took two years and produced over 10 terabytes of data. The first data set was released in 2017, and it contained 2 billion objects, most of which were also stars.
The survey focuses on the galactic disk, where most of the galaxy’s stars and dust are located. But the high density makes the region difficult to observe. The DECam Plane Survey overcomes this by performing “deep photometric surveys spanning a broad wavelength range (optical to NIR).”

Zamani & D. de Martin (NSF’s NOIRLab)
“One of the main reasons for the success of DECaPS2 is that we simply pointed at a region with an extraordinarily high density of stars and were careful about identifying sources that appear nearly on top of each other,” said Saydjari. “Doing so allowed us to produce the largest catalogue ever from a single camera, in terms of the number of objects observed.”
The two data releases combined cover 6.5 percent of the night sky and span 130 degrees in length. That’s 13,000 times larger than the area of the full Moon. While 6.5 percent might not sound like a lot, it is. It’s even more impressive when combined with other sky surveys.
“When combined with images from Pan-STARRS 1, DECaPS2 completes a 360-degree panoramic view of the Milky Way’s disk and additionally reaches much fainter stars,” says Edward Schlafly, a researcher at the AURA-managed Space Telescope Science Institute and a co-author of the paper. “With this new survey, we can map the three-dimensional structure of the Milky Way’s stars and dust in unprecedented detail.”
“Astronomers will be poring over this detailed portrait of more than three billion stars in the Milky Way for decades to come.”
Debra Fischer, division director of Astronomical Sciences at NSF.
The galactic plane is difficult to observe. We’re embedded in it, and when we look toward the center, we’re looking through our arm of the Milky Way, through the central disk and beyond, into the spiral arms on the other side. It’s not just that there are hundreds of millions of stars—maybe way more—in this view. This is where most of the dust is located, too.
The image shows how beautiful and intriguing the dark lanes of dust are, but they’re also problematic. They absorb light from stars and can even block out faint stars entirely. There are many diffuse nebulae as well, and their light interferes with measurements of light from individual stars. The vast number of stars is also a challenge since they can overlap one another.
But understanding the central disk is critical to understanding the Milky Way. Observing in infrared helps overcome some of the challenges of observing the disk. Innovative data processing also helps. The team behind the survey came up with a way of predicting the background of each star. That made it easier to minimize the effects of overlapping stars and diffuse nebulae in the images.
“This is quite a technical feat. Imagine a group photo of over three billion people, and every single individual is recognizable!” says Debra Fischer, division director of Astronomical Sciences at NSF, one of the agencies that operates DECam. “Astronomers will be poring over this detailed portrait of more than three billion stars in the Milky Way for decades to come. This is a fantastic example of what partnerships across federal agencies can achieve.”
“Since my work on the Sloan Digital Sky Survey two decades ago, I have been looking for a way to make better measurements on top of complex backgrounds,” said Douglas Finkbeiner, a professor at the Center for Astrophysics, co-author of the paper, and principal investigator behind the project. “This work has achieved that and more!”

A century ago, we didn’t even know there were other galaxies. When astronomers saw the Andromeda galaxy and other spiral galaxies, they thought they were part of the Milky Way. They called them spiral nebula. Now we know better. We also know that the Milky Way is 90% dark matter and that the galaxy isn’t flat; it’s warped due to the Large and Small Magellanic Clouds tugging on it. We know that there’s a behemoth black hole lurking in the galactic center called Sagittarius A-star. We also know that galaxies grow so large by consuming and merging with other galaxies.
Large-scale astronomical surveys of the sky helped astronomers make some of these discoveries, and DECaPS promises to propel us to similar advancements. The first data release helped lead to some very interesting findings. One example is a 2018 paper that identified an old, metal-poor globular cluster in the galactic bulge. That was unusual since most globular clusters are in the galactic halo. Now, thanks to DECaPS and others, we know of many more globulars in the bulge.
The second data release will no doubt lead to many more discoveries and a filling-out of our knowledge about the galactic plane. “Combined with PS1, this completes comparable imaging of the entire Galactic plane essential for probing our Galaxy’s stars, gas, and dust,” the authors write. All of the data products from the survey “…should provide a rich, adaptable resource for the community, facilitating a variety of studies of the Milky Way,” they explain.

We’re fortunate because our galaxy, the Milky Way, is a good model for understanding galaxies in general. About half of the stars in the Universe are in galaxies that are quite similar to ours. While nothing can be assumed, it’s a reasonable assertion that much of what DECaPS tells us about the Milky Way will have some bearing on other galaxies.
Astronomers have strived to understand galaxies and how they formed and evolved. The most comprehensive way to study them is to perform large surveys of stars like this one. Who knows what researchers will find in all of this data?
Here are some things on Mars, that the NASA rover just passes by without even a second look. The most significant evidence of an intelligent alien species is not a book, not mathematics, not alien technology. Its the actual faces of the aliens we speak about. Here I show you three great detailed faces. Two of them, are side by side, showing statues. One has no hat, the other has a huge crown like hat, showing its importance. This person with the hat, clearly a leader of great importance to this Mars culture.
“Volledige Romeinse stad” ontdekt bij opgravingen in Luxor
In de Egyptische stad Luxor zijn de resten ontdekt van “een volledige Romeinse stad” uit de eerste eeuwen na Christus. Dat heeft het ministerie van Oudheden bekendgemaakt.
Luxor was in de oudheid gekend als Thebe en was de belangrijkste stad van Opper-Egypte. Volgens het ministerie is nu “een volledige residentiële stad” uit de tweede en derde eeuw ontdekt “op de oostelijke oever van de Nijl, in de buurt van de Luxortempel”.
Eerder werden ook al metaalateliers met tal van werktuigen en Romeinse koperen en bronzen munten opgegraven, zegt Mostafa Waziri (het hoofd van de Egyptische Raad voor Oudheden; nvdr) “En de opgravingen gaan door.”

EXCLUSIVE: Metallic-looking orb is seen flying over Iraqi city of Mosul in 2016 - first ever publicly revealed UFO footage taken by US spy plane in a conflict zone - as expert warns of 'significant risk' to troops overseas
EXCLUSIVE:Metallic-looking orb is seen flying over Iraqi city of Mosul in 2016 - first ever publicly revealed UFO footage taken by US spy plane in a conflict zone - as expert warns of 'significant risk' to troops overseas
DailyMail.com has exclusively obtained an image of a 'metallic' orb flying over Mosul, Iraq in April 2016, from footage taken by a US intelligence-recon plane
It was obtained by journalists Jeremy Corbell and George Knapp, who have released the image on their new UFO podcast, 'Weaponized'
The sighting in a conflict zone where the US military is operating has sparked security and safety concerns at the Department of Defense
DailyMail.com obtained an exclusive image of a metallic-looking orb flying over an Iraqi city, caught on video by a US spy plane.
The image, captured in April 2016 by an intelligence-reconnaissance plane, was included in a classified briefing video on UFOs shown to multiple US government agencies.
The briefing video describes it as a 'short clip of an unidentified flying orb that appears to have a metallic shine on its surface', and shows the strange object flying over the city of Mosul in northern Iraq with the background of the shot showing the streets below.
It is the first publicly revealed image from the US government's ongoing UFO investigation showing an unidentified craft over a conflict zone.
A UFO flying around where the US military is operating has sparked security and safety concerns at the Department of Defense, with military officials worried it could endanger pilots and ground troops.

(image credit: DoD/Jeremy Corbell)
One intelligence source said the video was sent to the Joint Base Langley-Eustis in Virginia, where imagery and electronic signals intelligence experts studied it for United States Central Command (CENTCOM)
Although the image itself is not classified, footage from which the image was captured was part of a classified briefing produced by the Pentagon's Unidentified Aerial Phenomena Task Force (UAPTF), a unit tasked with investigating UFO incidents, which has now been replaced by another office in the Department of Defense.
The briefing describes and shows the UFO as moving from south to north, adding that it does not appear to descend.
In a four-second video titled 'Mosul Orb' included in the briefing, the UFO appears for one second as it flies alongside the MC-12 spy plane.
The photo was obtained by documentary filmmaker and investigative journalist Jeremy Corbell (pictured) and journalist George Knapp
Intriguingly, the object appears to have no apparent flight surfaces like wings, or discernible propulsion.
An intelligence source with operational knowledge of the footage said it was filmed using 'FMV [full motion video] by DGS-1' – implying that the plane sensors captured infra-red and other data when it filmed the UFO.
DailyMail.com understands that officials who assembled the briefing video believe the 'orb' was under intelligent control.
One intelligence source said the video was sent to the Joint Base Langley-Eustis in Virginia, where imagery and electronic signals intelligence experts studied it for United States Central Command (CENTCOM).
Despite being analyzed and studied by intelligence experts for over six years, the incident remains unexplained.
DailyMail.com can now reveal that the case formed part of the Office of the Director of National Intelligence (ODNI) Preliminary Assessment on UFOs, a report published in May 2021 which analyzed 144 cases and found an explanation for just one.
It comes a few months after the Office of the Director of National Intelligence (ODNI) published a second UFO report this month, which said it has analyzed 510 cases up to August 30, 2022
The ODNI published a second report this month, which said it has analyzed 510 cases up to August 30, 2022.
One source who had seen the report described dozens of videos on classified servers showing metallic-looking orbs captured by US spy planes or drones in the Middle East – similar to the image released today.
'These drones operate 20-25,000 feet up in the air and they're flying around. We're keeping an eye on bad guys all over the world,' the source said.
'An operator will be zoomed in looking at a town in Syria. And all of a sudden, a little orb will go flying through the viewfinder.
'The operator's like, ''What the hell?'' And so he starts focusing on it and he just watches the orb for a while. We might get it for 30 seconds, we might watch it for 10 minutes. And then it will do something remarkable, like suddenly bolt off the screen.'
The image obtained by DailyMail.com was taken at 9:47am Coordinated Universal Time on April 16, 2016, according to its timestamp.
There were also precise coordinates of where the image was taken in northern Iraq, but Corbell told DailyMail.com he removed them out of an abundance of caution to avoid the release of sensitive information.
CENTCOM forces have been deployed in the Middle East since 2014 to conduct military operations against ISIS.
DailyMail.com understands that Congressional intelligence and defense committees have seen the image and footage, as part of a briefing given by the Unidentified Aerial Phenomena Task Force (UAPTF), a previous incarnation of the government's UFO office.
In May 2021, Corbell published videos from the warship incidents that set social media ablaze
Still images and briefing slides from a video show a spherical object diving into the Pacific Ocean off the coast of California in 2019. Jeremy Corbell told DailyMail.com last June that the video shows 'FLIR [forward looking infrared] data' that is complimented by the radar footage
Corbell and Knapp said they will be releasing information, photos and videos in the podcast that they have been holding for 'years'
Corbell said that the briefing presentation was updated on shared classified intelligence servers on November 4, 2021, to encourage and inform reporting of UFOs by armed forces personnel – and that it has been shared with the wider intelligence community to keep them updated about UFO incursions into sensitive airspace.
He said the spherical shape of the object captured in Iraq is reminiscent of similar UFOs encountered by naval aviators operating on the US east and west coast every day, but is more complicated since it is occurring in an active conflict zone.
'For the first time, we are releasing a military-filmed image of a UAP over an active conflict zone,' Corbell said. 'This is an entirely different scenario to the east and west Coast incursions over training ranges.
'UAP [unidentified anomalous phenomena] pose significant risk to our service men and women, and this case highlights this – and is unfortunately not unique.
'This is not just about safety concerns to pilots and ground troops. Its potential consequences are far deeper. And the scope is now proven to be global.'
A source close to the military's current UFO investigations office, the All-domain Anomaly Resolution Office (AARO), said there are 'more cases like this one'.
'We have investigated a lot of UAP cases over the years and there are many more cases like this one. And this one was indeed part of the official UAP investigations by the UAPTF and now DoD's AARO. And it is still unresolved.'
Corbell added: 'No matter where UFOs are from, it is now openly admitted by our Department of Defense that they are appearing with an increased frequency worldwide.
'UAP, at minimum, pose a fundamental intelligence and combat identification problem that must be addressed.
'It's time to acknowledge the UFO problem, and I am hopeful that ARRO and its stakeholders will dedicate robust resources to this enduring mystery on behalf of the American and global public.'
This case has emerged following the approval by President Joe Biden of the Fiscal 2023 National Defense Authorization Act, which contains provisions relating to UFOs.

One clause in the new law offers protections for any whistleblowers coming forward to congress in classified briefings to disclose any previously hidden programs on 'unidentified anomalous phenomena' involving 'material retrieval, material analysis' and even 'reverse engineering' and 'developmental or operational testing'.
In May last year Congress held its first hearing on UFOs in 50 years.
He gained notoriety after producing a popular Netflix documentary on Bob Lazar, who claims to have worked at the infamous Area 51 in Nevada on recovered alien spacecraft.
George Knapp, who reports for Las Vegas CBS affiliate KLAS-TV, became a noted figure among UFO enthusiasts after his first interview with Lazar in 1989, and has written books on the government's UFO programs. He has won two Peabody awards and other gongs for his reporting.
Corbell and Knapp said they will be releasing information, photos and videos in the podcast that they have been holding for 'years'.
The first episode, released today, includes audio of an interview with a naval officer from the USS Paul Hamilton who witnessed alleged UFOs swarming the ship in July 2019.
'It was actually coming from the west,' the officer told Corbell in the recording. 'Over water away from land, I mean like, the only thing we have over there is Hawaii, which is probably the closest thing west of us.'
Other witnesses say the alleged UFOs 'shot down beams of light', and swarmed several other ships that were also conducting exercises in the Pacific Ocean off the US west coast that month.
Last year the Pentagon said they had identified the craft as drones, but could not confirm where they came from or who operated them. Corbell's witness was skeptical of the drone theory.
'They would depart on different bearings that they would come in from,' the officer said.
'Pretty constantly, it would be a different bearing, which is weird right, like so if you deploy a drone to check something out, it would come. So that was something significant enough for us.'
The first ever publicly revealed UFO footage taken by US spy plane in a conflict zone: “Metallic-looking orb seen flying over Mosul, Iraq”
The first ever publicly revealed UFO footage taken by US spy plane in a conflict zone: “Metallic-looking orb seen flying over Mosul, Iraq”
An image of a metallic-looking orb flying over Mosul, Iraq in April 2016, was included in a classified briefing video on UFOs shown to multiple US government agencies.
DailyMail.com has obtained an exclusive image of a metallic-looking orb flying over Mosul, Iraq in April 2016, from footage taken by a US intelligence-recon plane.
The recent release of an exclusive image of a metallic-looking orb flying over Mosul, Iraq in April 2016, captured by a US intelligence-reconnaissance plane, has caused a stir among both the public and government officials. The image, which was included in a classified briefing video on UFOs shown to multiple US government agencies, is being considered as the first publicly revealed image from the US government’s ongoing UFO investigation showing an unidentified craft over a conflict zone.
A briefing video released by journalists George Knapp and Jeremy Corbell describes an unidentified flying object that has a metallic shine on it’s surface. It shows an unusual image of an object flying over Mosul in Iraq. The object, which has no apparent flight surfaces, has raised suspicion about its capabilities and origin.
The sighting in a conflict zone where the US military is operating has sparked security and safety concerns at the Department of Defense. Military officials are worried that the object could endanger pilots and ground troops, as it is not known whether it is a hostile or friendly aircraft. One intelligence source said the video was sent to the Joint Base Langley-Eustis in Virginia, where imagery and electronic signals intelligence experts studied it for the United States Central Command (CENTCOM).
The release of the image has reignited the debate about UFOs and their existence, with many experts and researchers calling for more transparency and investigation into the phenomenon. The image also raises questions about the capabilities and technologies of other nations and non-state actors, as the object does not seem to be of any known design or origin.
The US government has had a long-standing interest in UFOs and their potential threats to national security. In 1947, the Air Force created Project Sign to investigate the numerous UFO sightings that were being reported. The project concluded that the majority of UFO sightings could be explained by natural phenomena or human error, but some remained unexplained. In 1953, the Air Force created Project Grudge to investigate UFOs, but it was shut down in 1955 due to lack of funding and resources.
In 1969, the Air Force created the Office of Special Investigations (OSI) to investigate UFOs. The OSI closed in 1974 due to budget constraints, but the Air Force continued to investigate UFOs through its Foreign Technology Division. In 1977, the Air Force closed its UFO investigation program, stating that there was no evidence of a threat to national security.
The image was obtained by investigative journalist Jeremy Corbell and journalist George Knapp, both of whom are documentary filmmakers.
In 2019, the US government started investigating reports of unidentified flying objects. The Navy then formed a task force to look into these reports. The Pentagon also established a similar organization to look into these reports. The UAPTF was replaced by another agency within the Department of Defense.
The release of the image from Mosul raises questions about the capabilities of the UAPTF, and whether it has been able to provide any answers or explanations about the object. The image also raises concerns about the government’s ability to protect national security, as the object seems to be able to fly over a conflict zone without being detected or intercepted.
The image also raises questions about the government’s ability to protect national security, as the object seems to be able to fly over a conflict zone without being detected or intercepted. The object’s speed, altitude, and maneuverability are not known, but it seems to be able to fly in the vicinity of a US military operation without being detected or intercepted.
This raises concerns about the ability of the US military to protect national security, as it suggests that there may be other unidentified objects that are able to fly over US military operations without detection. This could potentially have serious implications for the safety and security of US military personnel and assets.
The image also raises questions about the government’s ability to protect national security in the face of new and emerging technologies. The object in the image appears to have advanced capabilities, such as the ability to fly at high speeds and altitudes, and maneuver in ways that are not possible with current technology. This suggests that there may be other nations or non-state actors that have access to similar or even more advanced technologies.
This incident has raised concerns about the US military’s ability to defend against threats from other nations. It also highlights the government’s vulnerability to technological changes, and it shows how quickly technological advances can be made.
The release of the image from Mosul also highlights the need for more transparency and investigation into UFOs and their potential implications for national security. The image raises questions about the government’s ability to protect national security, and it is important that the government provides answers and explanations about the object and its capabilities.
The government should be transparent regarding its investigations into reports of unidentified flying vehicles. It should also provide the public with the necessary information to understand the potential implications of these phenomena for national security. Doing so will help build public trust and confidence in its ability to protect the country.
In conclusion, the release of the image of a metallic-looking orb flying over Mosul, Iraq in April 2016 has raised serious concerns about the government’s ability to protect national security. The object’s advanced capabilities and the fact that it was able to fly over a conflict zone without being detected or intercepted suggest that there may be other unidentified objects with similar capabilities. This highlights the need for more transparency and investigation into UFOs and their potential implications for national security. It is crucial for the government to provide answers and explanations about the object and its capabilities, and to be transparent about its investigations into UFOs to address the concerns of the public.

The Credible Encounter: The 1954 Cennina UFO Landing and Encounter with Humanoids
The Credible Encounter: The 1954 Cennina UFO Landing and Encounter with Humanoids
Cover of “La Domenica del Corriere” November 14, 1954
The Cennina landing of 1954 is one of the most extraordinary UFO landing and contact cases ever recorded. On November 1, 1954, a woman named Rosa Lotti was walking into the small town of Cennina, Italy when she came across an unusual sight. In front of her stood a vertical spindle-like object, which she described as being “like 2 cones joined at their bases.” From behind the craft emerged two little men, who were only about 3 feet tall. The men approached Lotti with friendly expressions, with one of them even laughing. They spoke in a language that sounded like Chinese and proceeded to snatch the carnations and one of Lotti’s stockings from her. Lotti, understandably frightened, ran away.
After the encounter, a deep hole was found in the ground at the site. The men were described as wearing grey overalls, short cloaks, and helmets. They were no taller than a five-year-old child, but their bodies were in proportion. The object was described as a double cone, about 2 meters high and 1 meter wide in the middle. It was made of a shiny metal and had a glass door on the lower cone with two small seats inside. Lotti reported that she did not hear any sound coming from the object.
This incident is classified as a CE-III (Close Encounter III) by Dr. J. Allen Hynek, meaning that there was a close observation of animate beings associated with the object. Multiple witnesses reported the encounter, and physical evidence in the form of the hole in the ground was found. The Cennina landing of 1954 is considered one of the most extraordinary UFO landing and contact cases ever recorded, and has been mentioned by prominent UFO researcher Jacques Vallee as case No. 24 in his “Century of Landings.”
The Cennina landing is considered to be one of the most credible UFO cases on record due to the multiple witnesses and physical evidence. Rosa Lotti’s account of the incident is particularly detailed and consistent. She described the little men as being about 1 meter in height and wearing a sort of grey overall that covered their entire bodies, including their feet. They also wore short cloaks of a grey material, and over the one-piece overall they wore a sort of doublet, fastened with little buttons that looked like shining stars. Their trousers were tightly-fitting, “like the long underpants that our men wear in the winter.” Their faces were normal, but small, and they were no taller than a five-year-old infant.
The object they saw was described as a double cone, which was over 2 meters high. Its outside appeared to be made of polished light metal, and its lower cone had an open glass door. In the center of the spindle, which was the widest part of the object, there was a roundish glass, which closely followed the mysterious machine’s round shape.
The sighting was reported by multiple witnesses, and the physical evidence of the deep hole found at the site added credibility to the incident. The Cennina landing is also significant because it is one of the few cases where the occupants of the UFO were described as being human-like, rather than the more common descriptions of beings with large eyes and small mouths.
Despite the credibility of the Cennina landing, some skeptics have attempted to explain the incident as a misidentification or hoax. Some have suggested that Lotti may have mistaken a weather balloon or other man-made object for a UFO. However, Lotti’s detailed and consistent description of the object, as well as the fact that multiple witnesses reported seeing the object, make this explanation unlikely.
Some skeptics also believe that Lotti and her group staged the incident to make it look like a hoax. However, this theory is not supported by any credible evidence. The fact that the hole in the ground that was discovered at the site was almost a meter deep, and it was hard to fake, makes the incident more believable.

In conclusion, the Cennina landing of 1954 is considered one of the most extraordinary and credible UFO landing and contact cases on record. The detailed and consistent account provided by Rosa Lotti, multiple witness reports, and physical evidence all lend credibility to the incident. While some skeptics may attempt to explain the incident as a misidentification or hoax, there is no evidence to support these claims. The Cennina landing remains one of the most intriguing and unexplained UFO encounters in history.
