One of the most celebrated and debated UFO incidents of all time took place in Rendlesham Forest near Suffolk, England just after Christmas in 1980. United States Air Force personnel stationed at two former Royal Air Force installations in the area, RAF Bentwaters and RAF Woodbridge, told incredible stories about encounters with mysterious lights and metallic craft that seemed under intelligent control as they danced around and above the trees on the nights of December 26, 27 and 28 that year.

Now, an ex-detective and the author of a recently released book entitled Non-Human: The Rendlesham Forest Incidents: 42 Years of Denial, Gary Heseltine, is organizing a special tour. The Sun reported that the aim of this tour to take UFO enthusiasts and other curious souls deep into the heart of Rendlesham Forest, so they can visit the exact locations where these strange and unexplained events occurred over the course of three nights more than four decades ago.

On the nights of June 3 and 4, Heseltine will lead his tour group to various sites in the woods, as he relates the fascinating and frightening stories of the multiple witnesses to the UFO-related events that allegedly took place at those spots. It has been claimed that as many as 17 lighted objects were spotted by one or more witnesses, all of whom were serving in the US Air Force (USAF) at the time of the Rendlesham Forest incident.

Gary Heseltine and the Rendlesham Forest UFOs

Gary Heseltine is a retired British police constable and a UFO sightings field investigator who is currently the vice president of the International Coalition for Extra-terrestrial Research (ICER). He is widely recognized as one of the premier experts on the weird events reported at Rendlesham Forest.

Heseltine’s new book has been praised by readers and reviewers for the immense amount of detail it reveals about what the witnesses experienced and about how the US and UK militaries have apparently tried to cover up the truth about this astonishing incident. “The Rendlesham Forest incident has often been referred to as ‘Britain's Roswell’, and in terms of its significance in UFO history the comparison is well made,” Heseltine wrote in the introduction to his new book.

“However, I have to say that in many aspects the RFI, as it has become known, is very, very different in certain key areas,” he continued. “After almost 14 years of public research into the RFI, I can think of no other case that has been subject of so much disinformation and damaging internal witness ‘political’ infighting.”

Heseltine’s mission during his upcoming two-day summer tour will be to reveal the real story about the Rendlesham Forest incident. During the event, he aims to separate fact from fiction as relates to the supposed Unidentified Flying Object spotted there, not just for the benefit of the members of his tour group, but ultimately for the historical record as well.

The USAF abandoned the installations at Woodbridge and Bentwaters in the 1990s, and while the former was eventually converted to a British army base, the latter is now closed and is the site of a public park. Rendlesham Forest is now open to visitors and is quite heavily trafficked, by picnickers, hikers, cyclists and UFO and alien enthusiasts who can visit the park on their own to follow a nature trail that traces the path USAF personnel followed on the nights they were chasing UFOs.

Aliens, a Hoax or an Elaborate Prank?

It is fitting that the Rendlesham Forest incident is referred to as the British Roswell. The 1980 sightings on forest land adjacent to RAF Bentwaters and RAF Woodbridge have been vigorously discussed, debated and written about since the time they happened, and the alleged crash of a flying saucer near Roswell, New Mexico in 1947 is the only UFO incident that has generated more public interest.

The list of men who wandered through the woods chasing the lights and looking for landed craft on those remarkable nights included deputy commander Charles Halt and enlisted men Larry Warren, John Burroughs and James Pennington. These individuals are the most well-known of the Rendlesham witnesses, as all have been extensively interviewed and all have written their own books about the subject.

Their stories differ in some of the details, and both skeptics and believers alike suspect there have been embellishments and distortions. Back in 2017, the Mirror reported that Larry Warren’s claims have proven especially controversial. Nevertheless, the eerie and otherworldly nature of their accounts is consistent.

Interestingly, many suspect the Rendlesham Forest incident was real but did not involve aliens. They believe the sightings may have been a high-level hoax coordinated by the USAF itself, as part of a military psy-op meant to test the reactions of Air Force personnel when confronted with what seemed to be a real alien invasion.

Some media reports on the Rendlesham incident, including an article about the UFO tour just published in the Daily Mail, have claimed that the purported alien invasion was actually a prank carried out by personnel from the British Army’s Special Air Service (SAS).

Was the Rendlesham Forest UFO Incident a Prank?

This claim comes from a letter sent to researcher David Clarke in 2018, purportedly from a former SAS airman who said he and others in his unit had concocted this elaborate hoax as a way to get revenge on US Air Force personnel for an earlier incident. It seems the Air Force men had treated them rudely following a secret security exercise that required SAS personnel to penetrate the defensive perimeter of the RAF Woodridge base without US Air Force permission.

To perpetrate their UFO prank, the individual from the SAS said he and his cohorts had rigged lights and shot off flairs in Rendlesham Forest. The also claimed they had used remote-controlled kites and black helium balloons to carry lighted materials up into the sky. “A great deal of nocturnal Christmas fun was had at the expense of the USAF — and the matter should have ended there,” the anonymous source wrote.

“Unfortunately, a senior US officer (Lt Col Halt) led the US contingent out into the forest on the second night and took along his tape recorder,” he continued when discussing the Rendlesham Forest events. “The hovering and whizzing lights were sufficiently impressive for him to send a report to the MoD.”

The letter writer told Clarke that the truth about the matter had been disclosed privately to the US Air Force, and that people at the highest levels in both the US and UK military knew what had really taken place.

• Unprecedented Citizen Hearing on Disclosure of Extraterrestrial Presence to take place in Washington
• ‘Clearest Photo Ever’ of a Huge UFO, Advanced Military Tech, Or Just A Rock In Water?

Many media sources, including the Daily Mail reporter, take this claim seriously and report it as a likely explanation for what happened at Rendlesham. But the Daily Mail failed to mention that David Clarke, who is an experienced professional journalist currently employed as an associate professor in the Media Arts and Communication Department at Sheffield Hallam University, investigated the claims of the anonymous letter writer and determined them to be without merit.

It seems the letter’s assertions about what had been done didn’t match the eyewitness testimony about what had been seen. Additionally, military sources Clarke contacted said that SAS personnel would not have been able to pull off such a prank on secure air force grounds without being quickly apprehended. Topping it all off, David Clarke received the anonymous letter on April 1st, leading him to conclude (quite reasonably) that the letter writer’s revelations were an April Fool’s Day joke.

The Rendlesham Forest Incident: The Truth is Out There

The truth about the events at Rendlesham Forest will likely never be established with 100-percent certainty. Even if insiders or whistle-blowers were to come forward to reveal exactly what happened, they probably wouldn’t be able to prove their claims. Their statements would undoubtedly be rejected by skeptics if they said the events were caused by aliens and by many UFO researchers if they said they weren’t.

The upcoming tour will be open to everyone, regardless of their opinions on the matter. With Gary Heseltine leading the way, they will have an educated and knowledgeable narrator to guide them. Although he personally believes in the possibility of alien visitation, he is perfectly content to allow each participant to draw their own conclusions about the events that occurred at Rendlesham Forest in December 1980.

Space photo of the week: James Webb and Hubble telescopes unite to solve 'impossible' planet mystery

• Why it's so special: This James Webb Space Telescope (JWST) image has helped astronomers untangle a long-standing mystery about how planets form. The mystery arose more than 20 years ago, when the Hubble Space Telescope spotted the universe's oldest known planet, which formed earlier in the universe's history than scientists thought was possible.

Stars form in large clouds of gas and dust called molecular clouds. Any remaining gas and dust gather in disks around the stars. Planets, in turn, form from these disks. Scientists believed that early stars didn't have planets because there was a lack of heavier elements, such as carbon and iron, which are created by stars' nuclear fusion and supernova deaths. They thought that these heavier elements were essential for planet-forming disks to exist long enough for planets to form.

• Space photo of the week: The tilted spiral galaxy that took Hubble 23 years to capture

But in 2003, Hubble detected a massive planet orbiting an ancient star in the M4 globular cluster, which is about 5,600 light-years distant in the Milky Way. Globular clusters are extremely old and, therefore, lack heavier elements. The exoplanet is about 13 billion years old, which suggests that planets may have formed earlier in the universe's history than scientists thought was possible. But astronomers were unsure exactly how it formed so early in the universe's history

To learn more about the early universe, astronomers use proxies that have similar conditions to ancient galaxies. One such proxy is the star cluster NGC 346, a star-forming region within the Small Magellanic Cloud (SMC), a dwarf galaxy that orbits the Milky Way. Like early galaxies, the SMC lacks heavier elements and is made up mainly of hydrogen and helium.

When astronomers pointed Hubble at NGC 346, they found signs that planet-forming disks existed around stars for 20 million to 30 million years — about 10 times longer than theories predicted such disks could survive. However, the signs were faint, so astronomers needed further proof.

In 2023, JWSTused the unprecedented sensitivity and resolution provided by its Near Infrared Spectrograph and Mid-Infrared Instrument to confirm the existence of long-lived planet-forming disks in NGC 346.

The findings, published Dec. 16, 2024, in The Astrophysical Journal, affirm the Hubble result and suggest that the lack of heavier elements may slow the star's ability to disperse its planet-forming disk — giving planets more time to form. Another theory is that the initial gas cloud from which the star forms might be larger, resulting in a more massive, longer-lived disk.

High-Resolution Imaging of Dyson Sphere Candidate Reveals no Radio Signals

Dyson Spheres are a class of megastructures originally proposed by physicist Freemon Dyson, who proposed how advanced civilizations could create structures large enough to enclose their stars (thus harnessing all of their energy). Project Hephaestos, led by Prof. Erik Zackrisson, has published numerous papers exploring possible Dyson Sphere candidates using different methods and data sources. The fourth and most recent paper in the series focused on seven potential candidates (designated A to G) around M-type stars from a sample of 5 million detected by the ESA’s Gaia Observatory.

Previously, Ren and his team have investigated these candidates to identify possible natural explanations. As they explored in a previous paper, these include dust-rich debris disks that absorb light and re-emit it as infrared radiation. This will lead to an observed infrared excess, which Dyson proposed as a possible indication of his proposed megastructure. However, as they indicate in their most recent paper, the Project’s measurements do not appear to resemble typical debris disks. As Garrett explained to Universe Today via email:

“When I saw the original results from Project Hephaestos last year, I was skeptical – they had surveyed 5 million stars, and if you do that, there is a good chance your measurements might include emission from background sources. You don’t expect stars to show radio emission at this level, and it basically tells you that the radio emission is probably coming from background (radio) galaxies. But then you also need a special kind of galaxy that is faint in the optical but very bright in the infrared – the only galaxies I knew that had this characteristic are DOGs – Dust Obscured Galaxies.”

The team was also inspired by another paper by Jason T. Wright, a professor of astronomy and astrophysics at Penn State, the director of the Penn State Extraterrestrial Intelligence Center (PSETI), and a member of the Center for Exoplanets and Habitable Worlds (CEHW). In this paper, Wright hypothesized that a true Dyson Sphere might use radio emissions to discharge waste heat. This led them to consider the possibility that these candidates were indeed Dyson Spheres.

As Tongtian explained, they were also inspired by previous research by Garrett:

“Mike briefly argued in 2015 that even in a Kardashev Type I Civilization, where energy consumption is significantly higher than that of humans on Earth, their radio communication signals are too weak to detect. However, the Dyson Spheres could correspond to a Kardashev Type II Civilization—one that harnesses over a billion times more energy than a Type I Civilization. Therefore, regardless of whether the beings reside on planets or elsewhere near the Dyson Sphere, it might be possible to detect their use of similar electromagnetic technologies.”

To investigate these possibilities further, the team searched through data obtained by the enhanced Multi-Element Radio Linked Interferometer Network (e-MERLIN) and the European VLBI Network (EVN) for data on the brightest radio source (candidate G). To their surprise, they found that three candidates from Project Hephaestos had radio counterparts in the astronomy databases. As Tongtian explained, the most logical explanation is that these signals (including candidate G) were due to contamination from bright radio sources – Active Galactic Nuclei (AGN) – in the background:

“They shouldn’t belong to one civilization. Otherwise, many anomalous stars would be connected as a swarm in the sky, not isolated seven. At that moment, we realized that either different extraterrestrial civilizations located hundreds of light-years away all have mastered the same or similar advanced radio emission technologies, or these signals originate from some form of natural contamination. We preferred to assume that they were some natural objects beyond the Milky Way – and most likely to be hot DOGS.”

These results effectively confirmed their earlier hypothesis that at least some of the candidates identified by Project Hephaistos are contaminated by bright radio sources that are also very bright in the infrared wavelength. This causes them to mimic the characteristics that Freeman Dyson predicted and what astronomers expect from Dyson Spheres. However, this does not rule out the remaining six candidates and highlights the importance of thoroughly analyzing each candidate with high-resolution radio observations.

“We don’t know that all of the candidates are contaminated, but some, maybe all, probably are. I really hope some of them are indeed good Dyson Sphere candidates,” said Garrett. “This all shows that a multiwavelength approach is really required when looking for candidates in order to rule out background contamination.”

“The development of new astronomical instruments does not follow the rapid update cycles of consumer electronics—it takes decades,” added Tongtian. “Gaia (launched in 2013 and recently decommissioned) and WISE (launched in 2009 and expired in 2024) provided a crucial observational window. The next generation of similar probes may not be available for a long time, making it unlikely that a large-scale Dyson Sphere search program like Project Hephaistos will be conducted again in the near future. So the current seven Dyson Sphere candidates deserve to be carefully examined.”

Stranded NASA astronaut says she's lost ability to perform vital bodily function after being in space so long

• READ MORE:  NASA's stranded astronaut leaves ISS for the first time in months
• PODCAST: On Welcome to MAGAland - Trump’s response to the tragic D.C plane crash, plus is project 2025 really a myth?

By ELLYN LAPOINTE FOR DAILYMAIL.COM

One of NASA's stranded astronauts has revealed she has lost the ability to perform several basic tasks after being stranded in space for eight months. 

Sunita Williams admitted this week that she has forgotten what it's like to walk after spending 234 days in microgravity.

'I've been up here long enough, right now I've been trying to remember what it's like to walk. I haven't walked. I haven't sat down. I haven't laid down,' she said during a video call with students at Needham High School in Massachusetts on Monday. 

Williams, 59 and her crewmate, Barry Wilmore, 62, were supposed to spend eight days on the ISS when they embarked on their mission on June 5, but the Boeing capsule that took them was plagued by technical issues.

The capsule has since returned to Earth empty, leaving the two astronauts stuck on the ISS until at least late March when they can catch a ride home on SpaceX's Crew-9 spacecraft.

President Donald Trump said 'the two brave astronauts' were 'virtually abandoned by the Biden administration' and asked Elon Musk and SpaceX to 'go get' them.

'Elon will soon be on his way. Hopefully, all will be safe,' the president said. 'Good luck Elon!!!'

The 53-year-old billionaire vowed in a post to retrieve Wilmore and Sunita Williams 'as soon as possible.' 

otten how to walk after spending 234 days in microgravity Sunita Williams admitted this week that she has forg

Musk said he was asked by President Donald Trump to bring NASA's stranded astronauts home as soon as possible 

Musk's SpaceX was already tasked with bringing astronauts Williams and Wilmore back from the ISS prior to this new order due to Boeing's Straliner malfunctioning in space.

The capsule experienced helium leaks and thruster malfunctions before, during and after its launch.

By August, NASA decided Starliner was unfit to safely bring the astronauts home, and announced that Williams and Wilmore would instead hitch a ride back to Earth on SpaceX's Crew-9 capsule, which is currently docked to the ISS.

NASA previously said that Crew-9 would return home as soon as February, but the agency changed the mission timeline in December.

In a statement, officials explained that SpaceX needed more time to complete work on the Crew-10 capsule, which must launch to the ISS before Crew-9 can leave the ISS. 

Thus, the astronauts' return was pushed back to late March. By that time, they will have spent eight months in space. 

During long space missions, microgravity takes a toll on astronauts' bodies, causing significant muscle and bone deterioration.

For every month in space, astronauts' weight-bearing bones become roughly one percent less dense if they don't take precautions to counter this loss, according to NASA.

If Barry Wilmore and Sunita Williams do return in late March as expected, they will have spent 10 months on the ISS, which is two months longer than a standard long-term ISS mission

President Donald Trump asked SpaceX CEO Elon Musk to 'go get' two astronauts who remain stuck in space

And their muscles which are usually activated by simply moving around on Earth also weaken because they no longer need to work as hard, the agency says. 

When astronauts return from long-term space missions, it's not uncommon for them not to be able to walk under their own power.  

The recent statements from Musk and President Trump suggest the timing of Williams and Wilmore's rescue mission could change again, potentially bringing them home sooner. 

There are a couple ways SpaceX might do this, according to astrophysicist and science communicator Scott Manley.

One option is to launch Crew-10 earlier, which would also allow the Crew-9 capsule to bring Williams and Wilmore home earlier, he explained in a recent X post. 

Welcome to MAGALAND: Insider Trump's Second 100 Days - The podcast bringing you the latest news and gossip from the White House. Listen here. 

This would require SpaceX to finish work on the spacecraft ahead of schedule, but the company has not said that it is on track to do so. 

Option two is to allow Crew-9 to return to Earth before Crew-10 launches, Manley said. 

This would go against NASA protocol, which requires the agency to maintain a critical mass of astronauts on the ISS during the 'handover process,' or the overlap between a departing ISS crew's time on the space station and a new crew's arrival. 

This period allows the departing crew (in this case, Crew-9 and the Starliner crew) to share any lessons learned with the newly arrived crew (Crew-10) and support a better transition for ongoing science and maintenance at the complex, according to NASA.

The handover process helps operations on the ISS run smoothly, but it is not an absolute necessity. 

Should NASA opt to let the Crew-9 capsule leave the ISS before Crew-10 arrives, Russian Soyuz astronauts would be there to receive the Crew-10 astronauts. 

SpaceX's Crew-9 capsule launched aboard a Falcon 9 rocket in September. The capsule is currently docked on the ISS and ready to bring its crew plus Williams and Wilmore home by late March, unless NASA and SpaceX move its departure up

There are a couple ways SpaceX might do this, according to astrophysicist and science communicator Scott Manley.

One option is to launch Crew-10 earlier, which would also allow the Crew-9 capsule to bring Williams and Wilmore home earlier, he explained in a recent X post. 

This would require SpaceX to finish work on the spacecraft ahead of schedule, but the company has not said that it is on track to do so.

The handover process helps operations on the ISS run smoothly, but it is not an absolute necessity. 

Should NASA opt to let the Crew-9 capsule leave the ISS before Crew-10 arrives, Russian Soyuz astronauts would be there to receive the Crew-10 astronauts.

It's also possible that the timing of the Starliner crew's return will not change at all. 

When Musk stated he would bring the astronauts home 'as soon as possible,' he may actually have been referring to the current mission schedule, Manley said. 

What's more, it could be that 'Elon is trolling,' he added. In other words, these statements from Musk and Trump may be displays of political showmanship that do not actually promise any real changes to the rescue mission's timeline.

Neither SpaceX, NASA, nor the White House have made any official public  statements regarding a revised return date for Williams and Wilmore.

In an emailed statement, NASA told DailyMail.com: 'NASA and SpaceX are expeditiously working to safely return the agency's SpaceX Crew-9 astronauts Suni Williams and Butch Wilmore as soon as practical, while also preparing for the launch of Crew-10 to complete a handover between expeditions.' 

SpaceX and the White House did not  immediately respond to DailyMail.com's request for comment.  

Despite the astronauts' dramatically extended stay on the ISS, NASA has repeatedly stated that they are not stranded. 

The agency has also emphasized that NASA astronauts always train for lengthy missions, and that medical experts have been closely monitoring the Starliner crew's health as they endure the harsh conditions aboard the ISS, including low-gravity, heightened radiation exposure and the psychological stress of confinement. 

If Williams and Wilmore do return home in late March as expected, their mission will have lasted two months longer than a standard long-term ISS mission, which typically lasts six months.

But they will not break astronaut Frank Rubio's record for the longest stretch of time spent on the ISS, which is 371 consecutive days.

NASA says chances of 'city-destroying' asteroid hitting Earth have increased

• READ MORE: Study confirms asteroid Bennu contains building blocks of life

By ELLYN LAPOINTE FOR DAILYMAIL.COM

The odds of a 'city-killer' asteroid smashing into the Earth on December 22, 2032 appear to have ticked up slightly.

NASA previously estimated that Asteroid 2024 YR4, a nearly 200-foot-wide space rock, has a one-in-83 chance (1.2 percent) of striking our planet.

But now, the agency's 'Sentry' Earth Impact Monitoring system reports a one-in-77 chance (1.3 percent) of a direct hit.

Astronomers have also calculated a predicted impact zone that stretches from South America across the Atlantic Ocean to sub-Saharan Africa.

The asteroid has the potential to cause significant damage, especially if it lands in a densely populated area like a major city due to it being the size of another space rock that hit Earth in 1908 with a blast equivalent to detonating 50 million tons of TNT.

Though estimates suggest a very small increase in the likelihood of impact, astronomer and professor of planetary sciences at the Massachusetts Institute of Technology (MIT) Richard P Binzel told DailyMail.com that it is nothing to worry about. 

'The difference between 1.2 percent and 1.3 percent doesn't matter,' he said. 

'Until the data are sufficient to pinpoint which of these two final answers is correct, we can expect the probability numbers to wobble around a bit. This is simply how scientific data measurements play out,' he added. 

The current 'risk corridor,' or the geographical area where the 2024 YR4 is most likely to hit, runs from South America across the Atlantic Ocean to sub-Saharan Africa

Regardless, the odds of this asteroid impacting our planet are still very low.

Astronomers say it is much more likely to safely pass us by, coming within roughly 66,000 miles of Earth. 

Astronomers believe 2024 YR4 is roughly the same size as the Tunguska asteroid, which caused the most explosive impact in recorded history when it shot through Earth's atmosphere in 1908, reportedly killing three people.

It exploded in the air over Siberia in what's known as an 'air burst,' flattening an estimated 80 million trees over 830 square miles of forest.

If 2024 YR4 infiltrates Earth's atmosphere, it could cause a similar event, astronomers say. 

Alternatively, it could remain intact during the descent and slam into the ground, creating a massive crater and decimating human communities in the impact zone. 

Asteroid 2024 YR4 shot to the top of NASA's automated Sentry risk list that ranks known Near Earth Objects (NEOs) on how likely they are to collide with our planet. 

NEOs are asteroids and comets that orbit the sun and pass close to Earth. 

The recently found space rock, however, is currently the most threatening NEO astronomers are aware of, ranking as a three out of 10 on the Torino risk scale,  a tool for categorizing potential Earth impact events. 

It's a scale from zero to 10, with higher numbers indicating a greater risk of impact. 

Most NEOs never reach higher than two on the scale. 

Analysis of 2024 YR4's orbit indicates that the asteroid will come within 66,000 miles of Earth on December 22, 2032. But when orbital uncertainties are factored in, it turns out there is a 1.2 percent chance of it directly hitting out planet 

Asteroid 2024 YR4 is about the same size as the Tunguska asteroid, which caused the largest impact event in recorded history when it shot through Earth's atmosphere in 1908

The Tunguska asteroid exploded in the air over Siberia in what's known as an 'air burst,' and a blast equivalent to detonating 50 million tons of TNT that flattened an estimated 80 million trees over 830 square miles. Experts say Asteroid 2024 YR4 could cause a similar event

While NASA and astronomers worldwide are keeping a close eye on the incoming asteroid, they are unable to predict how much damage it would cause. 

Experts will need to determined the asteroid's composition and true size before calculated its impact, which can only be done when it moves closer to our planet Rankin told Space.com. 

'Size and composition are big players in possible damage, along with impact location,' he said. 

'It's hard to constrain size and composition with the current orbital situation, as it's outbound,' or moving away from us, he added.

Experts still aren't 100 percent sure how much damage a direct hit from 2024 YR4 would cause (STOCK)

But best way to measure an asteroid's size is with radar observations, he added.

This technique reflects radio waves or microwaves off an asteroid's surface and then analyzes the reflections to calculate its size. 

Astronomers may have a chance to perform radar observations in 2028 when the asteroid passes within roughly five million miles of Earth, Rankin said. 

Until then, astronomers must rely on the asteroid's absolute magnitude, or brightness, to indirectly estimate its size.

This calculation gives them a rough diameter of 196 feet, but this estimate assumes that the asteroid's surface has a certain level of reflectivity that may not be accurate. 

'If the asteroid has a darker surface, that number is too small; if it has a more reflective surface, that number is too high,' Rankin said.

Asteroid reflectivity depends on its composition, which also plays an important role in how space rocks behave once they penetrate Earth's atmosphere.  

'If [asteroid 2024 YR4] is made of stony material, it could cause a significant air burst and fireball reaching the ground,' Rankin said. 

'If made of iron, it will punch right through the atmosphere with little trouble and make an impact crater. This is why understanding not just the orbit but also the composition and size are so critical.'

Due to these risk scenarios, astronomers will closely study and monitor 2024 YR4 in the years leading up to its approach. 

But 'people should absolutely not worry about this yet,' Rankin said. 

'Impact probability is still very low, and the most likely outcome will be a close approaching rock that misses us,' he said.

Now that 2024 YR4 has been identified as a potential — but unlikely — threat, the race to learn as much about it as possible before 2032 is on.

• READ MORE:  Two more 'alien mummies' are found with slanted eyes and hair

By STACY LIBERATORE FOR DAILYMAIL.COM

The 'alien mummies' discovered in Peru have largely been dismissed as a hoax by the scientific community, but researchers studying the specimens believe otherwise.

Dr José Zalce, former director of the Mexican Navy Medical Department, has analyzed 21 of the strange bodies, finding 'fingerprints, bone wear, dental formations, muscular features and internal organs - proving they're 100 percent real biological organisms.'

He even claimed some were pregnant, 'making them impossible to fake or replicate fraudulently,' said Zalce who has testified under oath that the mummies are real following his six years of work with them.

Recent scans of a 'pregnant' mummy revealed what appeared to be an intact fetus that had the same physical characteristics of the corpses, which the team said was proof of authenticity.

The mummies first exploded on the scene when controversial UFO enthusiast and journalist Jaime Maussan ushered two small beings into Mexico Congress in 2023.

He claimed they were not part of 'our terrestrial evolution', with 30 percent of their genetic composition still 'unknown.'

Dr Zalce and his team, however,  have performed X-rays, CT scans with 3D reconstruction, fluoroscopy, DNA analysis, forensic fingerprinting and tissue sample examinations on each body for the last six years.

'These confirm with 100 percent certainty their organic, biofunctional, and skeletal anatomical authenticity,' Dr Zalce told DailyMail.com.

Researchers have been studying these 'alien mummies' for about six years, claiming them to be 100 percent real

The researchers conducted a recent scan of a mummy named 'Montserrat,' finding it was pregnant at the time of death, which they believe was at least 1,200 years ago

The mystery began in 2017 when Maussan and a team of self-proclaimed paranormal researchers said they found a mysterious three-fingered 'mummified humanoid' with an elongated skull near the city of Nazca.

The body was found covered in white powder, which the team said was used to preserve the remains.

And five years later, the tiny beings were paraded through Mexico's Congress where Maussan argued his case and did so on two occasions.

During the second meeting, he brought in a string of doctors who all said the bodies were those of real, once-living organisms - some experts claimed to have studied 'five similar specimens over four years.

Now, a group of researchers who have studied nearly two dozen specimens are 100 percent sure they are real.

Jois Mantilla, a Peruvian journalist, has worked closely with the team stands with the experts' conclusion, specifically when the fetus was discovered in a mummy named Montserrat.

'The fact that the fetus is a tridactyl [three-fingered being] makes it one of the most important proofs of the authenticity of these bodies,' he said.

Dr Zalce and his team have determined that the specimen was between 15 and 25 years old at time of due to its 'bodily condition, gestational state, and a comparison of her anthropomorphic bone structure.'

He estimated Montserrat's remains are from 1,200 to 1,600 years old.

Mantilla also believes the the mummies are remains from an unknown species of hominin due to having some physical characteristics of a human, while its hands, facial features, elongated skull and feet are completely different.

One specimen, named Montserrat, was found with a metallic-like object on its head that experts said said was placed on the body while it was alive

Dr José Zalce, former director of the Mexican Navy Medical Department, has analyzed 21 bodies , finding 'fingerprints, bone wear, dental formations , muscular features and internal organs - proving they're 100 percent real biological organisms'

'It could be a different species of hominid that had not been described before by science,' he said.

'We presume that these beings, so similar to humans, but different at the same time, may have been genetically created by combining genes as in the case of Maria.'

A study on the mummy named Maria, published in May 2024, found that it has biological similarities to that of a human - but with 'many morphological and anatomical structural differences.'

The creature's bones were observed to flow smoothly under the mummified casing, in a way that is found throughout the human body, and its elongated skull showed no signs of artificial cranial deformation.

Mantilla claimed that genes of a bamboo and chimpanzee were used to genetically modify a 'human from the East.'

However, scientists outside this group have also studied two mummies and found different results.

Forensic archaeologist Flavio Estrada, who led the analysis, said the claims that the two objects came from another word are 'totally false.'

'The conclusion is simple: they are dolls assembled with bones of animals from this planet, with modern synthetic glues, therefore they were not assembled during pre-Hispanic times,' he said in January 2024.

Researchers said the fingerprints are very unique as they are linear and not wavy like those of humans

'They are not extraterrestrials; they are not aliens.'

However, a former Colorado prosecutor and current defense attorney, who has examined one of the mummies, is also a true believer.

Joshua McDowell said: 'The bodies studied by Estrada were not related to any specimen that we have studied. They were folk dolls made to look like tridactyls confiscated at the airport.'

Estrada's statements have not stopped Zalce and his team from looking deeper into the mysterious bodies.

 'All serious researchers involved have confirmed that these are non-human bodies with unique anatomical differences, such as tridactyl, without any traces of artificial manipulation or alteration,' Dr Zalce said.

One of those differences, according to researchers, are the specimens' fingerprints do not correspond to any hominid, they are linear.

'Those of humans, hominids, are oblique, they are wavy, they are rounded shapes and these are totally linear,' Mantilla said.

'In some of the bodies, the number of fingers reach five, in others four and some have only three.'

Dr Zalce added that the mummies' 'authenticity is supported by fingerprints, DNA analysis showing remarkable differences from human DNA, and other surprising genetic and pathological findings.'

Experts speculated that the mummies could be a remains from an unknown species of hominin due to having some physical characteristics of a human, while its hands, facial features, elongated skull and feet are completely different

'We presume that these beings,so similar to humans, but different at the same time, may have been genetically created by combining genes as in the case of Maria,' they said. Pictured is Maria

Metallic plates have been found throughout other areas of the mummies' bodies, 'from the interior covering some bones to external attachments on the skin, forming a biofunctional implant with no signs of rejection,' said Dr Zalce.

'These polymetallic plates have been analyzed using [a light-based measurement], revealing an alloy composed of copper, cadmium, osmium, aluminum, gold, and silver,' he added.

'Notably, the silver has a purity of over 95 percent, which is rare in nature. Additionally, cadmium and osmium, relatively recent discoveries, are currently used in satellite communication and satellite structures.'

Montserrat was found with a metallic-like object on its head that Mantilla said was placed on the body while it was alive.

'They have been placed on the skin using a technique that we still do not know,' he said. 'In some cases, [like Montserrat], the skin has been seen to have grown around the implant.

'This gives us the understanding that these implants were used while the subject was still alive. They were not metal implants placed for ritual purposes.'

McDowell is helping the researchers work collaboratively with the Peruvian Ministry of Culture to complete additional genetic and forensic testing not currently available in Peru.

'There are a lot of unknowns about these tridactyl specimens that could be definitively answered through additional testing modalities not currently available in Peru,' he said.

'Our position is simply that they should be tested, in a legal and culturally sensitive manner, with the best methods available today.'

Scientists Use NASA Spacecraft Data to Predict Alien Contact

Using advanced star-mapping data from the Gaia mission, the researchers have pinpointed potential star systems that may have intercepted Earth’s messages and calculated when a response could arrive.

Tracing Earth’s Signals into Deep Space

In 1973, NASA sent its first interstellar radio signal via the Pioneer 10 spacecraft. Pioneer 10 traveled toward the star Aldebaran, approximately 65 light-years away, though it has yet to come close to this distant star.

Similarly, the Voyager 1 and Voyager 2 spacecraft, launched in 1977, transmitted signals as they journeyed beyond the solar system. Voyager 2 left the Sun’s heliosphere in 2018 and is now traveling through interstellar space. Along its trajectory, it passed near the direction of a brown dwarf star located about 24 light-years away.

As per The Debrief, by analyzing these trajectories and combining them with Gaia’s data, researchers have mapped where other civilizations might intercept Earth’s signals. The team predicts that if intelligent life near this brown dwarf intercepted Voyager 2’s signal, we could theoretically receive a reply by the early 2030s.

Using Gaia Data to Refine Predictions

The Gaia space observatory, renowned for producing the most accurate star maps in history, was instrumental in this research. By charting the positions and motions of stars, the researchers calculated the time required for Earth’s radio signals to reach specific systems and for a potential reply to return.

“Our estimates are based on the time it takes for light-speed signals to travel between stars,” said lead researcher Howard Isaacson, an astronomer at UC Berkeley. “If an extraterrestrial civilization intercepted our signals and chose to respond, their reply would also travel at the speed of light, taking years to reach us.”

This analysis also highlights specific systems where SETI researchers could focus their telescope time, maximizing the chances of detecting alien signals.

The Odds of Contact

While the predictions are scientifically grounded, Isaacson acknowledges the slim likelihood of receiving an alien signal. “The probability is low, but the potential impact of such a discovery is enormous,” he explained. “Even if we don’t find signals immediately, this research inspires new ideas and technologies for exploring the cosmos.”

The study has also drawn attention from UFO enthusiasts, some of whom speculate that significant extraterrestrial-related events might occur by 2027. However, Isaacson has distanced his work from such unverified claims, emphasizing that the research relies on scientific data rather than speculation.

This study represents more than just a search for alien life—it’s a testament to humanity’s curiosity and determination to explore the unknown. By leveraging cutting-edge technology and precise measurements, the research opens new doors for understanding our place in the universe.

“Whether or not we find extraterrestrial life soon, the effort to look inspires us to think bigger and imagine the possibilities,” Isaacson concluded.

Scientists Discover Vast Traces of Life Deep Beneath Earth’s Surface

The study shows that microbial life deep in Earth’s crust is far more diverse than previously thought, rivaling or even surpassing surface ecosystems in some cases.

“It’s commonly assumed that the deeper you go, the less energy is available, and the fewer cells can survive,” said Emil Ruff, a microbial ecologist at the Woods Hole Marine Biological Laboratory and lead author of the study. “But our research demonstrates that in some subsurface environments, diversity can match or exceed that of the surface.”

The researchers identified a universal ecological principle showing that subsurface microbial ecosystems are not anomalies but a significant and thriving part of Earth’s biosphere.

The Global Collaboration Behind the Discovery

This breakthrough is the result of an eight-year international effort that analyzed over 1,400 datasets from microbial ecosystems worldwide. A lack of standardization in microbial DNA data had long hindered global comparisons, but that changed with a project led by molecular biologist Mitchell Sogin of the Bay Paul Center.

Sogin and his team worked to harmonize data collection and analysis techniques, enabling researchers to compare microbial samples from diverse environments, such as caves in Utah and subsurface layers in Spain. This collaborative approach revealed striking similarities in microbial diversity across vastly different regions.

The study not only highlights the resilience of life on Earth but also provides a template for exploring life in extreme environments elsewhere in the solar system.

The discovery of microbial ecosystems thriving under extreme conditions has profound implications beyond Earth. These microbes rely on chemical energy rather than sunlight, making them analogous to potential life forms that might exist in subsurface environments on Mars or the icy moons of Jupiter and Saturn.

This research serves as a reminder of the untapped potential within Earth’s hidden ecosystems and reinforces the importance of international collaboration in uncovering the planet’s secret

“RESILIENCE knows what it means to be alone in the vastness of space. Looking back at Earth on Jan. 25, 2025, the lander was about 10,000km from our Blue Marble, poignantly capturing Point Nemo, the most remote place on our planet, about 2,688 kilometres from the nearest land.”

The most well-known picture of our Blue Marble came from astronauts on Apollo 17 in 1972. It appeared during a boom in environmental activism and helped people around the world understand the planet they live on and consider its future and our impact on it.

The second most well-known image of Earth is probably Carl Sagan’s Pale Blue Dot image. Voyager 1 captured that image in 1990 on its way to the outer Solar System. The spacecraft captured the image from 6 billion km away when it passed Saturn. Carl Sagan proposed the idea not for scientific reasons but to drive home the idea that humanity’s home was just a tiny dot in the dark.

It seems de rigueur now for space missions to turn around and capture an image of Earth on their way to their destinations.

OSIRIS REx did it.

So did Artemis 1’s Orion spacecraft.

So have Lucy and many others. Now, they’re as common as pictures of their homes that young people take as they leave for college.

Yet, we don’t seem to ever tire of them. For some reason.

Maybe it’s because we’re accustomed to looking at maps with borders and labels on them, emphasizing how we see our planet through a political and historical lens. In those images, the context is human.

"The RESILIENCE lander remains in excellent health as it continues to orbit Earth in its planned trajectory towards the Moon!" ispace updated about its lander's health as it shared the visual.

But images of Earth from space have none of that. They show the true context of our planet. It’s a brilliant blue sphere, rippling with life, delicate and precious. It’s at the mercy of greater events that go on elsewhere in the Solar System and beyond, events beyond our control.

The people at ispace might not have intended their image to trigger this type of thinking. But regardless, this image takes its place in a long lineage of images of Earth captured by our departing spacecraft.

Hopefully, that lineage will continue for a long time.

The research was conducted by Cole Nypaver and Thomas R. Watters, a postdoctoral student and Senior Geologist with the NASM’s Center for Earth and Planetary Studies at the Smithsonian Institute. They were joined by Jackie Clark, an Assistant Research Scientist with UMD’s Department of Geology. The paper detailing their findings, “Recent Tectonic Deformation of the Lunar Farside Mare and South Pole–Aitken Basin,” recently appeared in the Planetary Science Journal.

Based on previous research, scientists have determined that the Moon once had a magnetic field. Like Earth’s, this field was powered by a dynamo in the Moon’s interior caused by a liquid outer core (surrounding a solid inner core) that rotated opposite to its axial rotation. However, crystallization began in the Moon’s core about 4 billion years ago, causing this dynamo to disappear between 2.5 and 1 billion years ago. This led to the disappearance of its magnetosphere and volcanic activity, ceasing about 3 billion years ago. As Clark summarized in a recent UMD press release:

“Many scientists believe that most of the Moon’s geological movements happened two and a half, maybe three billion years ago. But we’re seeing that these tectonic landforms have been recently active in the last billion years and may still be active today. These small mare ridges seem to have formed within the last 200 million years or so, which is relatively recent considering the moon’s timescale.”

Using advanced mapping and modeling, Nypang, Watters, and Clark found 266 previously unknown small ridges on the Moon’s far side. These were largely arranged in groups of 10 to 40 ridges that likely formed in narrow areas 3.2 to 3.6 billion years ago where underlying weaknesses in the lunar crust may have existed. Based on a technique known as “crater counting,” the team found that these ridges were notably younger than other features in their surroundings.

“Essentially, the more craters a surface has, the older it is; the surface has more time to accumulate more craters,” said Clark. “After counting the craters around these small ridges and seeing that some of the ridges cut through existing impact craters, we believe these landforms were tectonically active in the last 160 million years.”

The team also noted that the ridges observed on the far side of the Moon were similar in structure to ones found on the near side. This suggests both were created by the same forces, possibly by shallow moonquakes first detected by the Apollo missions. Scientists have since deduced that these are caused by a combination of shifts in the Moon’s orbit and its gradual shrinking – which explains why the Moon still experiences landslides. Understanding the factors that shape the lunar surface is of immense importance to future lunar missions.

As Clark indicated, this presents opportunities for further studies of lunar evolution:

“We hope that future missions to the moon will include tools like ground penetrating radar so researchers can better understand the structures beneath the lunar surface. Knowing that the moon is still geologically dynamic has very real implications for where we’re planning to put our astronauts, equipment and infrastructure on the moon.”

Currently, 2024 YR4 has a 3 on the scale, which means it “merits attention by astronomers.” It is currently the only object with a number other than 0 on the Torino Scale, and it means a couple of things come into play. The first is that the International Asteroid Warning Network (IAWN) will work to pin down the orbit of the asteroid. Chaired by NASA, the IAWN coordinates with observatories around the world to make detailed observations of 2024 YR4. It will take time to gather enough data. But what will likely happen is that they will determine there is no risk of collision, and 2024 YR4 will be demoted to 0 on the scale.

The second thing initiated is the Space Mission Planning Advisory Group (SMPAG), chaired by the European Space Agency. They have a scheduled meeting next week when there will be some initial discussions about a possible mission to 2024 YR4 to shift its orbit. If we do find there is a real risk of impact, this group would ramp up quickly. But again, this isn’t likely.

Statistically, asteroids the size of 2024 YR4 strike Earth every couple thousand years or so. This is why astronomers track these objects and are constantly looking for more. So even though the odds of an impact are never zero, with planning and preparation we should be able to ensure that any real risk can be mitigated.

Near Earth Asteroid 2024 YR4 observed with the VLT

This is a sequence of observations of the Near Earth Asteroid 2024 YR4 carried out with ESO’s Very Large Telescope in January 2025, shortly after it was discovered in December 2024. The asteroid is the faint source moving diagonally against the background of fixed stars. Follow-up observations such as this one have found that, as of 29 January 2025, it has an almost 99% chance of safely passing Earth on 22 Dec 2032, but a possible impact cannot yet be entirely ruled out.

A summer barbecue transformed into a nightmare when lightning split the sky above Somerset, England. Peter Williamson dashed across his rain-soaked lawn to rescue his terrified dog, unaware that his next step would carry him beyond the boundaries of our world. 

His family watched in horror as a blinding flash illuminated his silhouette against the stormy sky. When their vision cleared, Peter had evaporated into thin air. 

The police launched a search, but found no footprints, no scorch marks, and no explanation for how a man could disappear from a walled garden. Sixteen witnesses swore they watched him vanish in plain sight. 

Three days passed before Peter materialized in his backyard, wearing unfamiliar clothes and carrying items that defied explanation. His memories painted a picture of a hospital that both existed and didn't exist, where reality shimmered like heat waves rising from summer pavement. 

The investigation into his disappearance uncovered something extraordinary: evidence suggesting Peter had slipped through a crack between parallel universes. 

A "crack between parallel universes" is a metaphorical concept in physics, often used to describe a hypothetical point or region where two separate parallel universes could potentially interact or intersect with each other, allowing for potential travel or communication between them. 

If such a "crack" existed, it would likely demand extraordinarily extreme conditions, exactly the kind Peter Williamson encountered during his disappearance. 

His impossible story forces us to question everything we think we know about the nature of reality.

• READ MORE: Loch Ness Monster finally solved...thanks to Prince William

By MICHAEL HAVIS FOR MAILONLINE

A monster hunter says 'the only possibility is Nessie' after catching a double-humped creature on camera in what's been called the first sighting of the year.

Eoin O'Faodhagain was watching Loch Ness via webcam when he spotted something rising and sinking in the water, estimated to be up to 20 feet long.

He said: 'I noticed a disturbance in the middle of Loch Ness, to the right of the screen.

'I saw a shape rise up out of the water, then submerge, four times in the same spot, which I considered to be highly unusual.'

He continued: 'I thought it could be Nessie, but first wanted to look at other options.

'I've ruled out a log – I've never seen a log emerging and submerging in the same spot, ever.

'And waves move along, they do not stay in the one place.

'It's far too large for any wildfowl or seals, and I've also ruled out divers or swimmers. The only possibility is Nessie.'

A monster hunter says 'the only possibility is Nessie' after catching a double-humped creature on camera in what's been called the first sighting of the year

Eoin O'Faodhagain was watching Loch Ness via webcam when he spotted something rising and sinking in the water, estimated to be up to 20 feet long

The footage, taken on Sunday around 1pm, was captured using a webcam at the Clansman Hotel maintained by Visit Inverness Loch Ness (VILN).

It's an unusually early time of year for the mythical monster to appear.

The Official Loch Ness Monster Sightings Register recorded only a handful of entries last year – the first of them in April.

'It could be the first genuine Nessie Sighting of 2025,' said Mr O'Faodhagain, 60.

'January would not be a popular month for Nessie sightings, maybe because there are fewer pleasure craft out on the loch.'

In Eoin's footage, which lasts only a few seconds, a pair of black humps can be seen rising and sinking in the water.

The monster hunter believes this could be the head and body of the beast.

He said: 'There was one long hump and a smaller hump to the right of this, which I surmised to be the possible head of the creature.

The footage, taken on Sunday around 1pm, was captured using a webcam at the Clansman Hotel maintained by Visit Inverness Loch Ness (VILN)

The Official Loch Ness Monster Sightings Register recorded only a handful of entries last year – the first of them in April

'That would mean it's positioned to move against the current.'

He added that the mysterious creature's behaviour, emerging and submerging repeatedly, was characteristic of other Nessie encounters.

He said: 'This type of behaviour has been documented in other live sightings at Loch Ness over the years, so you could call this a classic sighting.

'There is a strong resemblance to my only registered sighting last year, also captured on the Clansman webcam in July.

'That consisted of two humps as well – one small at the front, followed by a large hump behind it.'

Mr O'Faodhagain often logs on to watch the water from his home in County Donegal, Ireland.

Over the years, he's racked up multiple entries in the Official Loch Ness Monster Sightings Register.

The VILN webcams can be watched live online at visitinvernesslochness.com

What IS the Loch Ness Monster?

Rumours of a strange creature living in the waters of Loch Ness have abounded over the decades, yet scant evidence has been found to back up these claims.

One of the first sightings, believed to have fuelled modern Nessie fever, came in May 2, 1933.  

On this date the Inverness Courier carried a story about a local couple who claim to have seen 'an enormous animal rolling and plunging on the surface'.

Another famous claimed sighting is a photograph taken in 1934 by Colonel Robert Kenneth Wilson.

It was later exposed as a hoax by one of the participants, Chris Spurling, who, on his deathbed, revealed that the pictures were staged.

Other sightings James Gray's picture from 2001 when he and friend Peter Levings were out fishing on the Loch, while namesake Hugh Gray's blurred photo of what appears to be a large sea creature was published in the Daily Express in 1933.

Robert Kenneth Wilson, a London physician, captured arguably the most famous image of the Loch Ness Monster. The surgeon’s photograph was published in the Daily Mail on April 21, 1934 - however it was later proven to be a fake 

The first reported sighting of the monster is said to have been made in AD565 by the Irish missionary St Columba when he came across a giant beast in the River Ness.

But no one has ever come up with a satisfactory explanation for the sightings - although in 2019, 'Nessie expert' Steve Feltham, who has spent 24 years watching the Loch, said he thought it was actually a giant Wels Catfish, native to waters near the Baltic and Caspian seas in Europe.

An online register lists more than 1,000 total Nessie sightings, created by Mr Campbell, the man behind the Official Loch Ness Monster Fan Club and is available at www.lochnesssightings.com. 

So what could explain these mysterious sightings? 

Many Nessie witnesses have mentioned large, crocodile-like scutes sitting atop the spine of the creature, leading some to believe an escaped amphibian may be to blame.

Native fish sturgeons can also weigh several hundred pounds and have ridged backs, which make them look almost reptilian.

Some believe Nessie is a long-necked plesiosaur - like an elasmosaur - that survived somehow when all the other dinosaurs were wiped out.

Others say the sightings are down to Scottish pines dying and flopping into the loch, before quickly becoming water-logged and sinking.

While submerged, botanical chemicals start trapping tiny bubbles of air.

Eventually, enough of these are gathered to propel the log upward as deep pressures begin altering its shape, giving the appearance of an animal coming up for air.

EXCLUSIVE - Tim Peake reveals what life is REALLY like for NASA's astronauts stuck in space - and warns dirty laundry and cramped conditions are the least of their concerns

• READ MORE: Trump asks Musk to 'go get' the two stranded NASA astronauts

By WILIAM HUNTER

NASA astronauts Suni Williams and Butch Wilmore were only meant to visit space for an eight-day round trip.

That brief excursion has stretched into a stay aboard the International Space Station (ISS) that is now likely to last 10 months.

While many of us back on Earth might be sympathetic to their situation, there are very few people who really know what they are going through.

However, one person who knows exactly what Williams and Wilmore are feeling is Tim Peake, Britain's first astronaut to live on the ISS.

After arriving on the ISS in December 2015, Peake spent more than six months living in the same conditions as NASA's stranded astronauts.

According to Peake, Williams and Wilmore will be more than ready to come back to Earth, having now spent seven months aboard the station.

Speaking exclusively with MailOnline, Peake says: 'They'll be loving their time in space, but it's a long time to spend up there.

'They'll probably be looking forward to coming home.'

Suni Williams (left) and Butch Wilmore (right) have now been stranded on the International Space Station for seven months, after planning to stay for just eight days 

Tim Peake, Britain's first astronaut to live on the ISS, says that Williams and Wilmore will now be 'looking forward to coming home'

Wilmore and Williams first landed at the ISS on June 5 last year aboard the Boeing Starliner spacecraft.

The plan was to launch the experimental capsule into space, perform some routine tests, and briefly dock with the station before returning to Earth.

However, issues almost immediately arose after Starliner experienced a series of helium leaks and engine failures.

By the time the capsule arrived at the station, it had sprung more helium leaks and five of its 28 thrusters had failed.

After weeks of tests, NASA ultimately decided that Starliner wasn't safe enough to carry humans back to Earth.

In September, the doomed spacecraft was sent back empty leaving Williams and Wilmore stranded aboard the ISS until a replacement crew could be sent to relieve them.

NASA was so confident that the pair would be home in a week that they were not even packed a spare change of clothes.

Although the ISS has an area of 520 metres squared (5,600 square feet) the seven astronauts share their space with laboratories, gyms, docking and cargo bays, and toilets.

After arriving on the Boeing Starliner capsule in June last year, a series of technical issues meant that the NASA astronauts were unable to return home on the same spacecraft

With only four phone booth-sized 'sleep stations' in the Harmony Module, the remaining astronauts have to sleep tethered to the walls wherever they can find space.

And with mandatory exercise, no showers, and fewer changes of clothes, life aboard the station can often be hot, smelly, and uncomfortable. 

However, Peake says that the dirty laundry and cramped conditions will not be the worst thing about life aboard the station.

Peake says: 'The things I missed most while I was in space were fresh air and nature.

'I love the outdoors and getting out into nature. I love going hiking and climbing; so that was very hard.'

With the ISS whizzing around the planet 16 times a day, astronauts are treated to a near-constant reminder of what they are missing out on.

'On the ISS I would look down and see this beautiful blue planet beneath me,' says Tim.

'I'm sure they'll be looking forward to coming back to Earth.'

Tim 

Peake (pictured during a spacewalk) told MailOnline that the things he missed most on the ISS were 'fresh air and nature' 

The only time Suni Williams (pictured) has stepped outside the station since her arrival was for a six-hour spacewalk earlier this month 

Despite all the difficulties of being in space, Peake maintains that Williams and Wilmore won't be feeling hard done by.

He says: 'I don't think they'll be regretting a single moment that they've had in space.'

Peake adds that the pair will be keeping busy 'mucking in' as part of the regular ISS crew, taking part in scientific work, maintenance, and even spacewalks.

After their arrival, Williams and Wilmore were rolled into the ISS Expedition 72 crew with Williams taking the role of commander and Wilmore stepping in as flight engineer.

That means the stranded pair's time in space will be far from a relaxing holiday.

ISS expedition members are expected to work 16-hour days starting at 6:00 am GMT which include two hours of mandatory exercise.

The gruelling realities of working out in space are something Peake is intimately familiar with, having run the London Marathon remotely from the ISS's treadmill.

Just as Peake did during his stay on the ISS, Williams and Wilmore will also be undertaking daring spacewalks to work on the outside of the station.

Tim Peake says that Williams (left) and Wilmore (right) will be 'mucking in' as part of the regular ISS crew. That means conducting scientific work, making repairs to the station, and carrying out mandatory exercise

While Tim Peake says that the pair of stranded astronauts will not regret having gone to space, he adds that seven months is a long time to spend away from friends and family 

Earlier this month, Williams was joined by NASA astronaut Nick Hague on a six-hour spacewalk to conduct repair work on the outside of the station.

Today, Williams and Wilmore will step outside of the space station together for the first time since their arrival.

The duo will spend about six and a half hours in the vacuum of space making repairs and collecting samples to see if bacteria are growing on the exterior of the ISS.

During his own expedition in 2016, Peake became the first British spacewalker when he made a four-hour and 43-minute spacewalk to make critical repairs to a failed power regulator.

Contrary to some claims, Williams and Wilmore are not strictly trapped aboard the ISS.

The SpaceX Dragon capsule scheduled to take them home has been docked with the ISS since September and could leave at any moment should an emergency arise.

However, before the pair leave, a relief crew needs to arrive on the ISS to take over the day-to-day operation of the station.

Under the original plans, that crew was supposed to arrive in February, but that mission has now been pushed back.

Williams and Wilmore are scheduled to return to Earth on a SpaceX Crew Dragon capsule (pictured) in March or April. Their return has been delayed while SpaceX prepares its next spacecraft

Musk vowed in a post to retrieve Butch Wilmore, 62, and Sunita Williams, 59, 'as soon as possible'. However, it is not clear how it would be possible to conduct the rescue mission any earlier than planned

NASA has revealed that the new SpaceX capsule isn't going to be ready in time to hit that deadline.

The capsule isn't expected to arrive at the SpaceX facility in Florida until early January and will still need more than a month of testing before it is ready.

NASA is now targeting no earlier than late March 2025 to launch the rescue crew, meaning Williams and Wilmore might not get back to Earth until April.

This week Donald Trump claimed he had asked Elon Musk to 'go get' the pair of astronauts.

In a post on Truth Social, Trump wrote: 'I have just asked Elon Musk and SpaceX to "go get" the two brave astronauts who have been virtually abandoned by the Biden administration.

'Elon will soon be on his way. Hopefully, all will be safe,' the president said.

In a post on X, Musk wrote: 'Terrible that the Biden administration left them there so long.'

However, given that the SpaceX craft is not ready for flight it isn't clear how Musk plans to bring Williams and Wilmore home any sooner than planned.

UFO Whistleblower Claims Trump Is Being Lied To About Those Drones in New Jersey

"Someone is not presenting the whole story to our new president."

Just a week in, he seemingly kept good on that promise by having his inept press secretary, Karoline Leavitt, tell the public that there was nothing to see in the skies.

"After research and study, the drones that were flying over New Jersey in large numbers were authorized to be flown by the [Federal Aviation Administration]," Leavitt said during a briefing earlier in the week. "This information comes directly from the President of the United States."

Beyond its dismal sentence structure, the statement left much to be desired, including who did the "research and study" and whether that included similar drones seen flying in New York and elsewhere.

Dissatisfied with the White House's non-explanation, a user on X reached out to an Air Force veteran-turned-UFO-whistleblower named Jake Barber to ask for his thoughts.

"The activity there was not FAA approved. I know firsthand," Barber wrote. "I was assigned there specifically to look at the debacle from a FAA violation standpoint in order to give a basis to the FBI."

"Someone is not presenting the whole story to our new president," the whistleblower continued.

Considering that Trump is essentially trying to gut the entire government, it's certainly plausible that the FAA isn't telling him the whole truth.

But Barber's comments, especially about having worked on the Jersey drone investigation, should nevertheless be taken with a grain of salt.

Earlier in January, Barber took to the right-leaning NewsNation with an incredible story: that during his time in Air Force special ops, he encountered bizarre debris from UFOs, or "unidentified aerial phenomena" per Pentagon parlance.

"Just visually looking at the object on the ground, you could tell that it was extraordinary and anomalous," the former military official told the news station of the egg-shaped, SUV-sized objects he claims to have seen. "It was not human."

Like other ex-Pentagon-ers before him, Barber maintains that he worked for a secretive UFO retrieval office within the military. He said that after witnessing the massive and bizarre debris, it was confirmed to him that its origin was from "nonhuman intelligence."

As with everything, there should be no mutual exclusivity between the fishiness of the White House's drone "explanation" and the weirdness of Barber's UFO claims.

So who's telling the truth? Because this isn't "The X-Files," we probably won't ever know.

How Many Dimensions Does Our Universe Really Have?

Does our Universe have extra dimensions, and how do they influence our reality?

 Matthew S. Williams

While this kind of talk may sound like something farfetched or purely speculative, it is actually a vital part of our understanding of how our Universe works. If and when we determine how many dimensions our Universe has (and what each of them does), we will finally have a Theory of Everything (ToE) and know how it all fits together.

Dimensions 101

To break it down, the term “dimension” refers to any mathematical measurement. This can generally refer to a physical measurement (an object or space) or a temporal measurement (time). There are three dimensions that we experience daily, which define the length, width, and depth of all objects in our Universe (the x, y, and z-axis, respectively).

However, scientists maintain that to understand the laws of nature, one must include a “fourth dimension,” which is time. Without this coordinate, the position, velocity, and acceleration of objects in our Universe cannot be properly measured. It’s not enough to know where an object is in terms of three spatial coordinates. You also need to know when the object was where.

Beyond these four dimensions, theoretical physicists have ventured that there may be more at play. The number of dimensions varies, but the purpose behind extra dimensions is to find ways of unifying the known laws of the Universe, which theoretical physicists have been trying to do for about a century.

• Electromagnetism
• Weak Nuclear Force
• Strong Nuclear Force
• Gravitation

The first three forces are all described by the field of Quantum Mechanics and are associated with specific subatomic particles. Electromagnetism is associated with electrons (a lepton), which are responsible for electricity, magnetism, and all forms of electromagnetic radiation. That includes visible light (color), heat, microwaves, radio waves, ultraviolet radiation, and gamma rays.

The weak nuclear force deals with interactions between subatomic particles responsible for the radioactive decay of atoms and is associated with particles smaller than a proton (bosons). At higher energies, this force merges with electromagnetism, which has given rise to the unified term “electroweak force.”

The strong nuclear force governs particles that are the size of protons and neutrons (hadrons) and is so-named because it is approximately 137 times as strong as electromagnetism, millions of times stronger than the weak nuclear force, and 10³⁸ times as strong as gravitation. It causes quarks to come together to form larger protons and neutrons and binds them to create atomic nuclei.

Superstring theory, a variation on ST, requires the existence of 10 spacetime dimensions. These include the four dimensions immediately apparent to us (length, width, depth, time) and six more that are not. 

These extra six dimensions are curled up into a compact space. On order the string scale (10^-33 cm) we wouldn’t be able to detect the presence of these extra dimensions directly because they’re just too small. 

According to the theory, the fifth and sixth dimensions deal with possible worlds that began with the same initial conditions. 

The fifth dimension encompasses worlds with slightly different outcomes than ours, while the sixth is where a plane of possible worlds would be visible. The seventh dimension is where one could see possible worlds that started with different initial conditions and then branched out infinitely — hence why the term “infinity” is used to describe them.

On its face, the first possibility seems highly unlikely. After all, ongoing particle experiments — like those conducted with the Large Hadron Collider (LHC) — have confirmed that the Standard Model of particle physics is correct. Similarly, General Relativity has been confirmed many times over since Einstein formally proposed it in 1915.

That leaves us with the second possibility: that extra dimensions cannot be measured or characterized using current methods and experiments. A well-studied possibility is that dimensions are “curled up” at tiny scales, which means their properties and influence on spacetime could only be measured at subatomic levels.

Another possibility is “compactification,” where certain dimensions are finite or temporal in nature. In short, this theory posits that curled-up dimensions become very small or close in on themselves to form circles. If this is true, then the six extra dimensions would likely take the form of a Calabi–Yau manifold (these are shapes that satisfy the requirement needed for the six “unseen” spatial dimensions of string theory).

For astrophysicists and theoretical physicists, compactification and the idea that extra dimensions are tiny explains why the Universe still exists billions of years after its emergence. If these dimensions were larger, they would accommodate enough matter to trigger gravitational collapses and the formation of black holes (which would consume the rest of the Universe).

The fact that the cosmos still exists after 13.8 billion years, and shows no sign of being torn apart, would suggest that this theory is sound. Alternatively, the laws of physics may operate differently in these extra dimensions. Either way, there’s still the unanswered question of how we might observe and study them.

How do we find them?

So if the Universe really does have extra dimensions that are imperceptible to us, how are we going to find evidence of their existence and determine their properties? One possibility is to look for them through particle physics experiments, like those conducted by the European Organization for Nuclear Research (CERN) — the operators of the LHC — and other particle accelerator labs.

At CERN, scientists boost particles to high energies before smashing them together and measuring the resulting cascade of subatomic particles. Detectors gather clues about the particles, such as their speed, mass, and charge, which can be used to work out their identity.

Theories involving extra dimensions predict that there must be heavier versions of standard particles recurring at higher and higher energies as they navigate smaller dimensions. These would have exactly the same properties as standard particles (and so be visible to detectors like those at CERN) but at a greater mass. If evidence of these were to be found, this might suggest the presence of extra dimensions. 

To date, astronomers have been unable to see this far back in time since no telescopes have been sensitive enough. This will change in the near future, thanks to next-generation instruments like the James Webb Space Telescope (JWST), the Nancy Grace Roman Space Telescope (RST), the Extremely Large Telescope (ELT), and the Giant Magellan Telescope (GMT).

This coincides nicely with existing Dark Matter and Dark Energy surveys that are observing early comic history in the hopes of measuring their influence on cosmic evolution. Since some theorists venture that the existence of extra dimensions could help explain the “Dark Universe,” these observations could address several mysteries at once.

This dual approach is not unlike our current understanding of the Universe, which scientists can only understand in one of two ways — the largest (GR) and tiniest of scales (QM). By observing the Universe with a very wide and very tight-angle lense, we may be able to account for all the forces governing it.

Much like other ToE candidates, the belief that the universe is made up of ten dimensions or more is an attempt to take all the physical laws we understand and find out how they fit together. In that respect, it’s like assembling a puzzle, where each piece makes sense to us, but we are unaware of what the bigger picture looks like.

It’s not enough to put pieces together wherever they appear to match. We also need to have an overall idea of what the framework is, a mental picture of what it will look like when it is finished. This helps to guide our efforts so we can anticipate how it will all come together.

Could we travel to parallel universes?

But how would we get to one of those parallel universes?

The trick is to build a time machine. It doesn't matter how you do it; you just need to go back in time. Normally, going back in time introduces all sorts of nasty paradoxes, like the infamous grandfather paradox, or, less violently, inconsistent histories. Try going back in time and destroying your time machine. Now it doesn't exist, which means you can't go back in time to destroy it, which means it should exist.

Related:

Perhaps time travel into the past is forbidden for exactly these reasons, according to Stephen Hawking's chronology protection conjecture. Or perhaps time travel into the past is allowed, but with one strict rule: You can't change the past. This is known as Igor Novikov's self-consistency conjecture. But how could you go into the past without changing it?

One possible answer is that when you travel into the past, you don't go into your own past. Instead, you slip into another history. If you go back in time and kill Hitler, you're not killing the Hitler of your past; you're killing somebody else's. And in that alternate universe, Hitler was always killed by a time-traveling assassin from another universe. When you return to the future, you come back home, with an unchanged past.

The many-worlds interpretation offers a natural platform for creating these alternate histories. If the universe is constantly splitting and branching anyway, then time travel simply moves you from one of those branches to another. Or, in another possibility, when you go back in time, you create a new branch that didn't exist before.

While this all sounds neat and tidy, it runs into the slight complication that nobody has ever gotten it to work. We don't know how this process actually unfolds or through what mechanism the alternate history emerges.

Attempts to navigate the issue by studying quantum mechanics have had mixed results. Left to their own devices, quantum fields tend to go haywire when time machines are involved. You can stabilize them — if you give up some of the core tenets of the theory, like the correspondence principle or unitarity, which say that quantum processes eventually lead to macroscopic behavior and that fundamental reactions are reversible. Nobody is really willing to give those up, since they seem central to the theory — so we're stuck on that front.

Besides, even classical, non-quantum systems run into issues. Let's say you have a switch that can turn your time machine on and off — say, by opening or closing a wormhole. We don't know how the alternate histories can accommodate changes in their space-time structures like that, regardless of whatever quantum processes are happening on a subatomic level.

However, if we could build a time machine, we could easily test whether alternate histories are created. All we'd have to do is change something in the past that you remember. If you're not allowed to do it (say, no matter how hard you try, you just can't kill Hitler), then you know there's only one timeline with a past that is locked in stone. But if you accomplish the mission, then you know that alternate histories are real and that the many-worlds interpretation of quantum mechanics might be valid.

We don't know if any of this is possible. On the other hand, we can't exactly rule it out. Time travel into the past seems forbidden but for reasons we can't readily discern. Our past seems to be gone forever — but it's also possible that it's just one branch of many and that visiting alternate universes is as easy as … Well, it's not easy at all.

What Ancient UFO Sightings Reveal About Humanity’s Obsession With the Unknown

The earliest recorded observations of strange phenomena in the sky come from ancient civilizations. Sumerian and Babylonian cuneiform tablets, such as those in the Šumma ālu series from the second millennium B.C., describe shifting shapes and black meteors appearing in the heavens.

Ancient Sky Events: Signs, Omens, or Something Else?

The earliest recorded observations of strange phenomena in the sky come from ancient civilizations. Sumerian and Babylonian cuneiform tablets, such as those in the Šumma ālu series from the second millennium B.C., describe shifting shapes and black meteors appearing in the heavens. These texts often interpreted such occurrences as divine omens rather than mysterious visitors from another world.

Chris Aubeck, director of the Magonia Exchange—an archival project dedicated to UFO history—emphasizes the challenges of defining ancient accounts as UFO sightings. “There is no consensus on what constitutes the first recorded UFO sighting in history,” Aubeck explained. He points out that while ancient records document strange celestial events, their meanings were often tied to spiritual beliefs.

Greg Eghigian, a historian and professor at Penn State, agrees, according to Live Science. He notes that ancient accounts must be viewed within their cultural context. “These stories are disconnected from the societies in which they were created,” he said. What appears puzzling or extraterrestrial today was often a symbol of divine intervention, religious significance, or natural phenomena like comets or meteors.

The Nuremberg “Sky Battle” of 1561

One of the most vivid historical accounts of an aerial phenomenon occurred on April 14, 1561, in Nuremberg, Germany. Witnesses described orbs, crosses, and other shapes battling in the sky, accompanied by a mysterious black arrow-like object. Hans Glaser, a local artist, even created a woodcut illustrating the event, depicting the objects as they “fell from the sky, burning as they hit the ground.”

Although dramatic, this event was interpreted at the time as a divine sign or apocalyptic warning. Modern researchers note that the imagery and interpretation reflect the religious worldview of the era rather than evidence of extraterrestrial visitors.

UFOs Enter the Modern Era

The narrative around UFOs shifted dramatically in 1947 when amateur pilot Kenneth Arnold reported seeing nine fast-moving objects near Mount Rainier, Washington. He described their movement as resembling a saucer skipping across water, leading to the now-iconic term “flying saucer.”

Arnold’s account captured public imagination, sparking a surge in reported sightings and the birth of modern UFO culture. At the time, many people believed these objects were advanced military aircraft rather than extraterrestrial visitors, reflecting Cold War-era anxieties.

“This sighting is widely regarded as the event that kick-started modern UFO culture,” Aubeck stated.

While UFO sightings continue to fascinate, they often reveal more about human culture than the mysteries of the cosmos. “Studying UFO sightings is valuable because they represent the urban legends of our time,” Aubeck explained. These stories demonstrate how cultural narratives and imagination shape the way we interpret the unknown.

Throughout history, people have gazed upward and wondered about the mysterious lights, shapes, and movements that defied explanation, weaving them into the fabric of their culture and beliefs. For ancient civilizations, these celestial events were often interpreted as messages from gods, warnings of impending events, or signs of divine favor. In more recent times, they’ve evolved into symbols of scientific intrigue, Cold War paranoia, and even hopes for extraterrestrial contact.

I believe that UFOs, in this sense, are far more than just strange objects in the sky. They represent the stories we tell ourselves about our place in the universe. Are we alone? Are there forces beyond our comprehension shaping our destiny? Every sighting, whether dismissed as a natural phenomenon or celebrated as a groundbreaking discovery, invites us to confront these timeless questions.

This enduring curiosity and creativity reveal something deeply human: our ability to turn the unknown into stories, myths, and hypotheses.

Astronomen zijn continu het heelal af aan het speuren op zoek naar verre werelden en andere interessante ruimte-objecten, maar het is zoeken naar een speld in een hooiberg. Australische wetenschappers hebben nu een nieuwe technologie ontwikkeld die mysterieuze hemellichamen opspoort door inkomende radiosignalen op bijzondere wijze te filteren. Deze innovatieve aanpak heeft in korte tijd al een aantal verrassende resultaten opgeleverd.

Astronomen en ingenieurs van CSIRO, het nationale wetenschappelijke agentschap van Australië, hebben hun krachten gebundeld en CRACO (CRAFT COherent detector) ontwikkeld. CRACO bestaat uit een cluster van computers en processoren die verbonden zijn met de ASKAP-telescoop, gelegen in het gebied van de Wajarri Yamaji-gemeenschap in West-Australië. Dit geavanceerde systeem is ontworpen om vliegensvlug raadselachtige verschijnselen, zoals fast radio bursts (FRB’s), op te sporen.

FRB’s en neutronensterren

De technologie is nu voor het eerst getest en een nieuwe studie laat zien dat CRACO al een aantal bijzondere ontdekkingen heeft gedaan: er zijn twee FRB’s geïdentificeerd, maar ook twee neutronensterren die met tussenpozen actief zijn, en het is gelukt om de locatiegegevens van vier pulsars sterk te verbeteren. Sindsdien zijn met het systeem nog eens meer dan twintig FRB’s opgespoord.

Hoofdonderzoeker Andy Wang van ICRAR maakt duidelijk dat de resultaten veel spectaculairder zijn dan het team ooit had kunnen denken. “Ons doel was om fast radio bursts te vinden, een mysterieus fenomeen, waaromheen een geheel nieuw onderzoeksgebied binnen de astronomie is ontstaan”, legt een enthousiaste Dr. Wang uit. “Met CRACO kunnen we deze flitsen beter detecteren dan ooit tevoren. Momenteel zoeken we naar signalen met een snelheid van 100 flitsen per seconde, en in de toekomst verwachten we dit te verhogen naar 1000 flitsen per seconde.”

Een kosmische zandzeef

CSIRO-astronoom Dr. Keith Bannister vergelijkt de schaal waarop CRACO waarnemingen doet met het zoeken naar een speld in een hooiberg. “CRACO benut ASKAP’s liveweergave van het heelal om FRB’s op te sporen. Het systeem verwerkt hierbij gigantische hoeveelheden data – zo’n 100 miljard pixels per seconde – om bursts te detecteren en hun locatie te bepalen”, legt Bannister uit. “Het is alsof je een heel strand afzoekt naar een muntje van vijf cent, en dat elke minuut opnieuw.”

Volgens Dr. Wang belooft CRACO een revolutie teweeg te brengen in de internationale astronomie, zodra het systeem op volle capaciteit werkt. De technologie is ontworpen om de triljoenen pixels die de telescoop ontvangt, te analyseren op zoek naar afwijkingen. Zodra iets ongewoons wordt gespot, geeft CRACO de wetenschappers direct een seintje, zodat zij snel extra gegevens kunnen verzamelen en de vondst verder kunnen analyseren.

Indrukwekkende technologie

Het onderzoeksteam zit niet stil: CRACO’s mogelijkheden worden continu uitgebreid om nog exotischere verschijnselen te detecteren. “Naast fast radio bursts van buiten ons sterrenstelsel detecteren we nu ook zogenaamde ‘langzame transiënten’. Dit zijn kortdurende hemelverschijnselen die door mysterieuze objecten binnen onze Melkweg worden veroorzaakt. Beide fenomenen zijn in Australië ontdekt, en het is geweldig dat we met deze indrukwekkende technologie verder kunnen gaan. Er liggen ongetwijfeld nog een aantal fantastische ontdekkingen in het verschiet”, zegt Wang.

Mysterieuze signalen uit het universum: fast radio bursts

Fast radio bursts (FRB’s) zijn korte, intense uitbarstingen van radiostraling die afkomstig zijn van onbekende bronnen in het universum. Ze duren slechts enkele milliseconden, maar in die korte tijd kunnen ze evenveel energie uitstralen als de zon in een heel jaar. Sinds hun ontdekking in 2007 blijven FRB’s astronomen fascineren. Veel FRB’s lijken eenmalig te zijn, maar sommige vertonen een repeterend patroon. Het is onduidelijk waar FRB’s vandaan komen. Mogelijke verklaringen zijn magnetars (extreem krachtige neutronensterren), gammaflitsen en botsingen tussen massieve objecten, zoals zwarte gaten of neutronensterren. Ook exotischere theorieën, zoals signalen van buitenaardse technologie, worden geopperd.
