The Annual Perseid Meteor Shower Peaks This Weekend and It Is A Must-See Event
The Annual Perseid Meteor Shower Peaks This Weekend and It Is A Must-See Event
Make a wish — or, with 50 to 100 meteors streaking across the sky every hour, make several.
This weekend is the perfect time to catch the year’s most spectacular — and easiest to watch — meteor shower, the Perseids.
The annual Perseid meteor shower will peak late on Sunday night and into the early predawn hours of Monday morning, but the Perseids should put on a spectacular late-night show from now through the middle of next week. Here’s everything you need to know, from how to watch the Perseids to the science behind the light show.
The Perseids are known for long, bright streaks of light.

When Is the Perseid Meteor Shower?
Short answer: Right now! The Perseid meteor shower happens around this time every year, from mid-July to early September, with a dramatic peak around August 12.
Meteor showers like the Perseids are a vivid reminder that we’re passengers on a ball of rock moving through space at more than 67,000 miles per hour — and right now, we’re flying through a stream of dusty debris left in the wake of a comet. Comet 109P/Swift-Tuttle makes a long loop around the Sun every 133 years, and it leaves a trail of dust, ice, and pebbles in its wake. Every year, at about the same point in Earth’s 365-day lap around the Sun, our planet crosses Swift-Tuttle’s debris trail. As that debris patters against Earth’s upper atmosphere, like bugs hitting the windshield of a passing car, it creates bright streaks of light in the sky.
What to Expect from the Perseid Meteors
At the peak of the Perseid meteor shower, between 50 and 100 meteors an hour will streak across the night sky. That’s a meteor or more every minute, so your chances of seeing several meteors are very good.
The Perseids are known for leaving bright, colorful streaks of light that can linger in the sky for several seconds; the longest, brightest streaks come from meteors that just skim the top of our atmosphere, instead of plunging straight in. Most of the streaks of light you’ll see during the Perseids are objects about the size of sand grains, disintegrating 50 miles above you at temperatures hotter than 3,000 degrees Fahrenheit. Larger grains, usually about an inch across, can burst apart in bright fireballs; if you’re lucky, you may spot a few of those an hour.
How to See the Perseid Meteors
The Perseids are one of the easiest meteor showers to watch, mostly because it offers so many meteors streaking across the sky, but also because Swift-Tuttle’s debris trail is so wide that we get several days of good viewing, unlike other meteor showers that may offer only a few hours of real meteor-watching. If the weather or your personal schedule don’t cooperate on the night of August 11, you can still see a fantastic show a few days before or after the shower’s peak.
As with any stargazing, darkness is key. You’ll want to get as far away from city lights as possible. The ideal meteor-watching spot is dark, with a wide-open view of as much of the sky as possible, but especially the north. Bring a lawn chair or blanket, and settle in. Turn off your headlights, flashlights, and cell phone, and give your eyes about 30 minutes to adjust to the darkness.
For casual viewers, meteors should be visible anytime after around 10pm local time, but the best views will be after midnight, when the bright half-Moon sets and leaves a dark sky for meteors to shine against. And the dark pre-dawn hours of Monday morning will offer the most and brightest meteors.
If going outside isn’t your thing, you can catch the Virtual Telescope Project’s livestream, starting at 9pm Eastern Time on August 11 and August 12.

Do the Perseid Meteors Come from Perseus?
Short answer: no.
If you stare up at the night sky for long enough, you may notice that the Perseid meteors seem to radiate from a point somewhere in the constellation Perseus. It may look a little like the classic Windows 95 Starfield screensaver (for the history buffs out there who remember screensavers). That’s an optical illusion; as Earth flies through the cloud of dust and debris, the direction in which we’re moving will look like the center, from which all the meteors seem to radiate out and past us. In the case of the Perseids, that point is somewhere in the constellation Perseus, in the northern sky.
But the Perseid meteors are actually just bits of dust and tiny pebbles that, at this moment, are in a cloud all around us.
Is Comet Swift-Tuttle Going to Crash Into Earth Someday?
Short answer: maybe, but not anytime soon.
Comet 109P/Swift-Tuttle is the largest object that regularly crosses Earth’s orbit and passes close to our planet, so astronomers have kept a close eye on it. They’ve calculated its orbit, and ours, for about the next 2,000 years, and Swift-Tuttle is in no danger of hitting Earth until sometime after the year 4400 (and even then, the chances aren’t huge). So you can relax and enjoy the show.
If Swift-Tuttle eventually does hit Earth, it’s going to wreck everything. The nucleus — the actual ball of ice and dust that forms the main body of a comet — of Swift-Tuttle is about 16 miles wide, which makes it twice the size of the object that smashed into the Yucatan Peninsula 65 million years ago and ended the dinosaurs’ world. Because of how much faster Swift-Tuttle moves in relation to Earth, though, it would hit with about 27 times as much force as the Chicxulub object.
The two Boeing Starliner astronauts may remain onboard humanity’s farthest outpost for half a year more. Not everyone at NASA thinks the spacecraft has been proven safe enough to bring them back from Earth orbit.
When NASA’s associate administrator of space operations Ken Bowersox addressed reporters on Wednesday, internal debates within the space agency surfaced. The concerns were regarding the safety of Starliner’s two astronauts, Suni Williams and Butch Wilmore, who’ve already been living in space two months longer than planned.
They flew into space on June 5 for what was, at the time, set as an eight-day mission. The mission was called Crew Flight Test and was meant to be a certification of Starliner’s abilities to become a commercial crew program spacecraft — second to the now tried-and-tested SpaceX Crew Dragon — that could bring spacefarers to the International Space Station (ISS) and back safely at a low cost to NASA.
With Starliner, NASA seeks comfort. If something goes wrong in space or with SpaceX’s launchers, astronauts can rely on Starliner to make it to space without interruption in the timelines.
Things went awry soon into the mission. Thruster and helium leak anomalies didn’t stop Starliner and its crew from successfully docking to the ISS, but raised serious concerns about how they would return home.
Problems arise on test flights, and that’s what the evaluative nature of these flights are for: to catch blindspots and remedy. But days, weeks and, now, months have passed.
To figure a way forward, NASA and Boeing have run hot fire tests of Starliner in space. And on Earth, engineers have put spare thrusters through the gamut at NASA’s White Sands Testing Facility in New Mexico to replicate the conditions that the hardware in space has gone through. They believe the thruster issue is due to overheating, plus swelling of a teflon seal that blocks the flow of fuel into the thruster’s combustion chamber. “What we're trying to do now is sort of understand what all that data means to us from the White Sands testing, and then what it means to the thrusters on orbit,” NASA Commercial Crew Program manager Steve Stich said Wednesday.
As teams figure out the ramifications of the worst case scenario for thruster overheating, as well as of the helium leaks experienced during Starliner’s journey to the ISS,the test crew remains in space. Their return date continued to be pushed into the future. Their arrival home could now be as late as next year.
Don’t overstay your time in space
Tensions clashed last month, when Boeing Commercial Crew Program manager Mark Nappi scolded reporters during a press briefing for using language that called the astronauts “stranded” or “stuck” in space. Reporters pushed back asking for clearer responses from NASA and Boeing leadership as to when they’d come home, and more frequent updates on the Starliner troubleshooting. Then during a follow-up media conference, Nappi and Stich expressed regret that they had outlined the mission as an eight-day event, to avoid scrutiny.
Test flight or not, missions must adhere to schedule windows. The ISS is an aging spacecraft. To maintain its functions, astronauts are swapped in and out on assignments. Having two extra astronauts aboard the station strains the resources, occupancy, and schedules of the other space crews. That’s not even taking into account the private, personal tolls that the extended missions may have on the crew. Or, the physical changes they’ll experience as a result of longer periods in microgravity.
As a consequence of the idle Starliner, the SpaceX Dragon Crew-9 mission will no longer launch in mid-August with its crew of four. Its launch date has been pushed to September 24. Its crew may also be halved to open up two free seats for Wilmore and Williams to return home as a backup plan. But Crew-9 wraps up its six-month mission in February 2025, meaning the Starliner crew would come home eight months past schedule.
Not everyone at NASA agrees on Starliner’s safety
The same day that Bowersox and his colleagues announced the new Crew-9 launch date, he opened up about the internal discussions that have kept the Starliner crew from returning home.
“It's been really great to watch our team working, our Boeing team, our NASA team, the way people are speaking up. The way we're hearing different voices, different thoughts on how critical different factors are in the decision,” Bowersox said Wednesday.
“I think it's been very healthy. I have to admit that sometimes when we get disagreement, it's not fun. It can be painful having those discussions. But it's what makes us a good organization. And it's what will get us to a good decision as we approach that point here in the future. And I don't think we're too far away from making that call,” he added.
Starliner may still yet return with its crew. Data from recent tests and new evaluations might finally bring the team to a consensus for how — and when — to finally bring Williams and Wilmore home.

Why Experts Believe the Pentagon Covers Up UAP Reports
Why Experts Believe the Pentagon Covers Up UAP Reports
In a recent episode of Reality Check, journalist Ross Coulthart delves into the Pentagon’s handling of Unidentified Aerial Phenomena (UAP) reports. Joined by NewsNation correspondent Xavier Walton, the discussion uncovers a deep-seated skepticism among experts regarding the transparency and authenticity of these investigations. This article explores why experts believe the Pentagon might be covering up information about UAPs.
Historical Context and the DNI Report
The turning point in the UAP discourse came in June 2021 when the Director of National Intelligence (DNI) released a groundbreaking report. This document, titled “Preliminary Assessment: Unidentified Aerial Phenomena,” acknowledged the reality of UAPs and their potential threat to national security and flight safety. This admission was significant as it marked a departure from decades of stigma and denial surrounding UAPs within the U.S. government.
The AARO Report Controversy
Fast forward to 2024, and the Pentagon’s All-domain Anomaly Resolution Office (AARO) released its much-anticipated historical review of UAPs. However, this report was met with criticism from experts who felt it lacked objectivity and thorough investigation. The AARO report was seen by many as an attempt to discredit longstanding allegations of a secret U.S. program aimed at retrieving and reverse-engineering alien technology.
Experts like ufologist Don Schmidt and military veteran Kevin Randall, both prominent figures in UAP research, expressed disappointment in the AARO report. They argued that it failed to provide new information and did not engage in rigorous investigation, merely reiterating what was already known without substantiating any claims.
Expert Opinions and Skepticism
Don Schmidt, the lead investigator for the UFO Museum in Roswell, and Kevin Randall, an author of over three dozen books on UFOs, have long been vocal critics of the government’s handling of UAP reports. Schmidt’s stance is that asking the very entities responsible for the cover-up to come clean is futile. He believes that AARO will continue to dismiss the subject, maintaining that there is no extraordinary evidence of alien technology in the government’s possession.
Randall echoes these sentiments, highlighting the lack of verifiable information in the AARO report. He criticizes the report for its inability to provide checkable data, leaving researchers with nothing to substantiate the government’s claims.
Public Perception in Roswell
The sentiment of disappointment and skepticism is not limited to experts. During the Roswell UFO Festival, NewsNation’s Xavier Walton engaged with locals and attendees who expressed similar frustrations. Many locals in Roswell, a town synonymous with the famous 1947 UFO incident, remain convinced that the government is not disclosing the full truth about UAPs. This skepticism is rooted in decades of independent research and witness testimonies that contradict official explanations.
Historical Investigations by Independent Researchers
Schmidt and Randall have dedicated years to investigating the Roswell incident, conducting detailed interviews with first-person witnesses and gathering substantial evidence. Their meticulous approach starkly contrasts with what they perceive as the Pentagon’s superficial efforts. For instance, interviews with individuals like Walter Haut, who issued the original 1947 press release claiming the recovery of a flying disc, and Major Jesse Marcel, the intelligence officer who inspected the crash site, reveal a different narrative than the one presented by the government.
Lou Alzando’s Revelations
Adding to the controversy, a leaked book by Lou Alzando, a former Pentagon UAP investigator, claims that the Roswell crash was indeed of extraterrestrial origin. This revelation, if verified, would provide semi-official confirmation from someone within the Pentagon, further fueling beliefs of a cover-up.

Why experts think the Pentagon covers up UAP reports | Reality Check with Ross Coulthart
The skepticism towards the Pentagon’s UAP investigations reflects a broader mistrust in governmental transparency. Despite official denials, many experts and the public remain convinced of a cover-up, supported by decades of independent research and compelling witness testimonies. As researchers like Don Schmidt and Kevin Randall continue to seek genuine disclosure, the call for accountability and transparency in UAP investigations grows louder.
In conclusion, the persistent belief in a Pentagon cover-up of UAP information is bolstered by historical context, expert analysis, and public sentiment. The debate continues as the quest for the truth about UAPs remains a contentious and unresolved issue.
NASA Discovers Galaxies Older Than the Universe Astronomers were left stunned after NASA’s powerful James Webb Telescope captured several galaxies deep in the cosmos that appear to be older than the universe itself.
This sparked significant and engaging debate among astronomers about how such a thing is possible. Here's what the experts have to say about the strange phenomena.
The Beginning of the Universe Astrophysicists believe the universe was formed at least 13.8 billion years ago following a significant event commonly referred to as the Big Bang.
Prior to this, the entirety of the universe’s energy is theorized to have been concentrated in a singularity, defined as a point of infinite temperature and density. As this singularity began to expand, it resulted in an explosion dubbed the Big Bang.
The Fundamental Forces of Nature Appear After the violent explosion that gave birth to the universe as we know it occurred, the fundamental forces of nature, including electromagnetism and gravity, alongside the strong and weak forces, evolved in stages.
These led to the eventual formation of galaxies. However, observations carried out using the state-of-the-art James Webb Telescope have noticed that certain earlier galaxies appear to have skipped the gradual process of evolution, giving the impression that they are older than the universe itself.
The Webb Telescope Observes Early Galaxies The powerful Webb telescope can essentially peer back in time and observe galaxies when the universe was a mere 500 million years old, or 3% of its current age.
As the cosmos was still considered in its infancy at this period, researchers predicted small galaxies scattered throughout the universe. However, the JWST has observed galaxies that were far larger than previously anticipated.
Webb Telescope Makes Fascinating Discovery The galaxies spotted by the JWST contain a mass of stars that could be as much as 100 billion times the mass of the Sun.
To better understand this enormous cluster of stars in the early galaxies, we can compare it to our own galaxy, the Milky Way, which only contains a mass of stars equal to approximately 60 billion suns.
How is This Possible? The question that continues to perplex astronomers is how such an extensive number of celestial bodies and extensive galaxies existed at such an early period of the universe.
To better understand this, we must explore "redshifting." According to the European Space Agency (ESA), “Redshift is a key concept for astronomers. The term can be understood literally—the wavelength of the light is stretched, so the light is seen as 'shifted' towards the red part of the spectrum.”
The Visible Light Spectrum In simple terms, redshift refers to a particular section of the visible light spectrum.
The shortest wavelength of light is violet, at around 380 nanometers. The longest is red, at around 700 nanometers. Astronomers use the latter to gather valuable data on the age of galaxies.
ESA Defines Redshift According to the ESA, redshift is used to measure how far a celestial object like a galaxy has moved away from us.
“When an object (e.g. a galaxy) moves away from us, it is 'red-shifted' as the wavelength of light is 'stretched' so the light is seen as 'shifted' towards to red end of the spectrum,” according to the ESA.
Redshift and Dating Galaxies Astronomers can use this redshift to predict the age of galaxies found throughout the universe, as all celestial bodies and objects emit a frequency or hue of color that telescopes can pick up. This red color will differ depending on how young or old the galaxy is, allowing researchers to effectively discern how old galaxies are in the depths of the cosmos.
Redshifting can also be used to instruct researchers on the extreme age of galaxies in the cosmos, as well as to analyze several other factors, including their size. Astronomers can also use redshift to scour the galaxy for massive stars and to give researchers an indication of how far a celestial body is from our own planet.
Galaxies During the Infancy of the Universe Continues to Perplex Astronomers As galaxies in the cosmos age, they produce more suns, which is generally expected. However, the galaxy spotted by the JWST during the universe's infancy has a mass significantly larger than that of the present-day Milky Way.
Despite their attempts to explain this unusual phenomenon, astronomers and researchers have come up empty-handed, and there is no accepted explanation just yet.
The Universe is 26.7 Billion Years Old, Says Researcher Physicist Rajendra Gupta from the University of Ottawa in Canada is one researcher who believes he has an answer to the question, suggesting “redshift could be a hybrid phenomenon, rather than purely due to the universe’s expansion.”
He added, “Our newly-devised model stretches the galaxy formation time by several billion years, making the universe 26.7 billion years old, and not 13.7 as previously estimated,” Dr Gupta said.
Why Early Galaxies Appear to Have Larger Masses The suggestion that the universe is twice as old as originally thought has stirred up considerable controversy in the scientific community.
Such a revelation could undoubtedly explain why early galaxies, which emerged 500 million years after the beginning of the universe, appear with a mass generally associated with billions of years of evolution.

Yes, I lived in Taiwan for 25 years and I recognize the languages and their accent. Raw video guys, what are we looking at here? Because it looks like it's the best UFO video ever recorded due to 1st it holding still so close to the top of the building. 2nd the eyewitness is very close, living in the penthouse (top floor) apartment. 3rd the UFO is seen powering up. 4th the UFO shoots away showing its incredible speed and power.
Het centrum van de Groenlandse ijskap is in een niet al te ver verleden gesmolten, zo blijkt uit een onderzoek: het onomstotelijke bewijs zijn fossielen die zijn gevonden in wat ooit een groene toendra was.
Ook het centrum van Groenland is in het verleden gesmolten
Tegenwoordig zien we Groenland als een witte ijsvlakte, maar ooit was dat helemaal niet zo. Voortdurende ontdekkingen over het verleden van dit ijzige gebied op aarde onthullen steeds meer ongelooflijke achtergronden, zoals het feit dat het er uitgesproken “groen” uitzag. Nieuw onderzoek heeft bewijs gevonden dat niet alleen de randen, maar ook het midden van de Groenlandse ijskap in een nog niet zo ver geologisch verleden is gesmolten en dat het “oude” landschap eruitzag als een toendra.
In 1993 werd een ijskern van meer dan 3 kilometer lang uit het centrale deel van het grondgebied gewonnen en vervolgens tot op de dag van vandaag bewaard in een afzetting in Colorado, VS. Nu heeft een groep wetenschappers opnieuw de sedimenten op de bodem van dit halfronde stuk ijs onderzocht en iets spannends ontdekt.
Fossielen in het midden van de ijskap
Halley Mastro/University of Vermont
Het team ontdekte dat de sedimenten schimmels, insectenresten, wilgenhout en een maanzaad bevatten, allemaal ongerept. Paul Bierman van de Universiteit van Vermont, co-auteur van het onderzoek samen met Halley Mastro, stelt: "Deze fossielen zijn prachtig."
Onderzoek heeft het feit bevestigd dat de enorme ijskap van Groenland in het verleden is gesmolten als gevolg van een bijzonder warme periode, waardoor een groen eiland is ontstaan. Aangenomen wordt dat dit in de afgelopen miljoen jaar heeft plaatsgevonden, wat betekent dat de ijskap veel kwetsbaarder is dan wetenschappers hadden gedacht. Sinds het ijs in het midden van Groenland smolt, spreekt het voor zich dat de rest van het eiland hetzelfde lot onderging en, volgens Bierman, duizenden jaren lang, genoeg om een terrein te creëren dat klaar was om een ecosysteem te huisvesten.
Richard Alley, klimatoloog aan de Pennsylvania State University, verklaarde na bestudering van de resultaten van het onderzoek: “Het bevestigt en breidt het feit uit dat een groot deel van de zeespiegelstijging plaatsvond in een periode waarin de oorzaken van de opwarming niet bijzonder extreem waren”, en ziet het als een waarschuwing voor wat er zou kunnen gebeuren als het klimaat verder opwarmt door toedoen van de mens.

De “kwetsbaarheid” van Groenland bevestigd
In feite stijgt de zeespiegel met 2,5 cm per jaar en in een versnellend tempo. Tegen het einde van deze eeuw zullen de oceanen naar verwachting ongeveer zes meter hoger stijgen dan nu.
In 2016 werd dezelfde ijskern, GISP2 genaamd, onderzocht door wetenschappers van Columbia University: de resultaten suggereerden dat de huidige ijskap niet ouder kon zijn dan 1,1 miljoen jaar en dat Groenland tijdens het Pleistoceen lange tijd zonder ijs heeft gezeten, minstens 90% van zijn grondgebied. In 2019 werden in een andere ijskern, die in de jaren ’60 werd gedolven, kleine takken en gefossiliseerde insecten gevonden die 416.000 jaar oud waren. Het huidige onderzoek bevestigde dat dit bevroren eiland niet zo sterk en veerkrachtig is als eerder werd gedacht: meer dan 3 meter ijs smolt gemakkelijk, waardoor er tijd en ruimte overbleef voor de ontwikkeling van een toendra.
Starliner-astronauten keren mogelijk pas in 2025 terug naar aarde

Starliner-astronauten keren mogelijk pas in 2025 terug naar aarde
De twee astronauten die begin juni met de Boeing-ruimtecapsule Starliner zijn aangekomen in het internationale ruimtestation ISS, moeten daar mogelijk nog tot 2025 blijven. Dat heeft het Amerikaanse ruimtevaartagentschap NASA gemeld.
Sunita Williams en Butch Wilmore zijn sinds 6 juni aan boord van het internationale ruimtestation (ISS). Hun testmissie zou ongeveer een week duren, maar door problemen met de Starliner kunnen ze voorlopig niet terugkeren.
NASA bestudeert nu twee mogelijkheden om hen terug naar de aarde te brengen. Een eerste optie is om hen toch met de Starliner te laten terugkeren, maar daarvoor moeten er wel nog werken aan dat ruimtetoestel worden uitgevoerd.
De tweede optie is om de Crew 9-missie van SpaceX in september met slechts twee van de vier voorziene astronauten te laten vertrekken. Wilmore en Williams zouden dan met hen kunnen terugkeren. Dat betekent dan wel dat ze tot februari volgend jaar vastzitten in het ISS.
Zealandia: het achtste continent dat onder de oceaan verborgen is
Zealandia: het achtste continent dat onder de oceaan verborgen is

Een achtste continent onder water
Wetenschappers uit Australië en Nieuw-Zeeland hebben onlangs een nieuw onderwatercontinent herontdekt, namelijk Zealandia.

Een groep eilanden
Het is in feite een groep eilanden die vergelijkbaar is met de eilanden waaruit Nieuw-Zeeland bestaat, met een oppervlak dat iets minder groot is dan de helft van Brazilië.

Een oud supercontinent Er wordt aangenomen dat Zealandia deel uitmaakte van het oude supercontinent Gondwana, dat enkele honderden miljoenen jaren geleden een groot deel van het zuidelijk halfrond van onze planeet bedekte.

Indrukwekkende afmetingen Volgens een artikel van de BBC zijn de afmetingen van dit ondergedompelde continent indrukwekkend: 4,9 miljoen vierkante kilometer.

De grootte van India Volgens een ander team onderzoekers, dat in 2017 het continent Zealandia voor het eerst claimde te hebben ontdekt, heeft het ongeveer dezelfde grootte als India, zo bericht Ouest France.

Bijna het gehele oppervlak bevindt zich onder water Het land van Zealandia maakte waarschijnlijk deel uit van een uitgestrekt gebied boven zeeniveau. Tegenwoordig bevindt 94% van het oppervlak zich echter onder water.

Wat is het precies? Gaat het om een groot eiland of een continent? Zoals de Times of India opmerkt, is er geen geologische parameter die een precieze grens tussen de ene of de andere term vastlegt, en maakt het daardoor onderwerp voor discussie.

Afgezonderd van het Australische continent Ondanks de nabijheid van Australië geloven wetenschappers dat de twee groepen afzonderlijk van elkaar bestaan. Al wordt de term 'Australazië' soms gebruikt om het volledige landgebied van het zuidwesten van de Grote Oceaan aan te duiden.

Gedetailleerde kartering Geowetenschappers hebben Zeelandia gedetailleerd in kaart gebracht, waarmee ook de locatie van vulkanische activiteit werd onthuld en belangrijke informatie over de opbouw van het continent werd verkregen.

Monsters genomen van de bodem in de oceaan Om deze kartering uit te voeren, verzamelden de onderzoekers geologische monsters van de landmassa die zich onder water in de oceaan bevindt.

Een schat aan mineralen Het tijdschrift Slate berichtte dat er een echte schat is aangetroffen: "Een mengsel van verschillende soorten zandsteen, basalt en kalksteen".

Magnetische afwijkingen De datering van deze monsters en het onderzoek van hun magnetische afwijkingen stelden wetenschappers in staat om de Zealandia op een waardevolle manier in kaart te brengen.

Waarom ligt Zeelandia onder water? De meest voor de hand liggende verklaring hiervoor is dat de tektonische platen door het uitrekken van Gondwana braken, waardoor het oceaanwater vrij spel kreeg.

Een dunne, ondergedompelde aardkorst Het loskomen van Antarctica zou de aardkorst van Zeelandia geleidelijk hebben verdund tot het land volledig was ondergedompeld.

Meer kennis over de eigenschappen van de aardkorst De ontdekkingen in Zealandia zouden wetenschappers meer kennis kunnen geven in waarom de aardkorst zo dun werd en zo sterk uitrekte.

Zijn er nog andere verborgen continenten? We weten niet of er meer onderzeese continenten zijn, omdat we eigenlijk maar weinig weten over de diepten van de oceanen. De ruige omgeving bemoeilijkt dit soort plekken. Daarom is deze recente ontdekking zo waardevol!
About 80 percent of Greenland is armored in a continuous sheet of ice, three times the area of Texas. But it hasn’t always been that way. At various points in Earth’s past, much of the island was, in fact, actually green — covered in soil and vegetation. The last period of thaw may have been more recent than previously thought, according to new research. The new data comes with worrying implications for present-day climate change and sea level rise.
Tiny organic fossils found deep under the ice in central Greenland show that the middle of the landmass was ice free, serving as habitat for growing plants and insects within the last 1 to 2 million years, per a study published August 5 in the journal Proceedings of the National Academy of Sciences. The exact age of Greenland’s ice sheet remains unresolved, but the ballpark suggested by the new findings bolster the formerly controversial “fragile Greenland” hypothesis, which suggested that the island’s ice sheet has melted at least once since it first formed. And if it thawed entirely before, then it could easily do so again under human-caused global warming, spurring even more dramatic sea level rise than current climate models indicate.
The Pleistocene era lasted from about 2.6 million years ago to the start of the Holocene, 11,700 years ago. During this period, our planet went through several freeze and thaw cycles where glaciers expanded during ice ages and contracted during interglacials. Previously, glaciologists and the research record have disagreed about what was happening on Greenland, during this epoch. For example, one 2016 study of mineral deposits in ocean sediments indicated that the ice sheet has persisted for 7.5 million years. In contrast, another study published that same year assessing isotopes in ice cores suggested that the ice sheet is just 1.1 million years old, with more than 280,000 years of ice-free conditions leading up to its last freeze.
The new research supports that latter finding. The study scientists re-evaluated sediments collected in a two-mile-deep ice core more than 30 years ago from Summit Camp, Greenland, a research station positioned near the very center of the ice sheet. Isotope analysis of quartz extracted from the sand at the bottom of the core suggests that it was buried under ice no more than 2 million years ago.
Isotope analysis of quartz extracted from the sand at the bottom of the core suggests that it was buried under ice no more than 2 million years ago.
Inside the previously frozen sediment, the researchers also identified miniature fossils of a bygone ecological age. Among other bits of remarkably well-preserved biological matter, the scientists found a poppy seed, moss remnants, insect parts, willow wood, and fungi — hallmarks of a tundra landscape. These fossil finds suggest that not only was the center of Greenland ice-free within the past 2 million years, but that it was also unfrozen long enough for soil and a complex ecosystem to form — likely for thousands and thousands of years. “Poppies don’t grow on top of miles of ice,” said Hailey Mastro, co-lead study author and a master’s student researching paleoclimatology at the University of Vermont, in the news statement.
The assemblage of organisms suggests Greenland’s climate was not much warmer than today’s at the time of this last melt, with summer temperatures between 1 and 10 degrees Celsius. Though an ice-free Greenland might be good news for cold-adapted flowers, it’s not good news for us. “This new study confirms and extends that a lot of sea-level rise occurred at a time when causes of warming were not especially extreme,” said Richard Alley, a geoscientist at Penn State who reviewed the research, in a press release. It’s “a warning of what damages we might cause if we continue to warm the climate,” he added. Past assessment of the same 1993 ice core determined that, if the center of Greenland was melted, then 90 percent of the island would also be ice-free.
Already, the Greenland ice sheet is the largest single contributor to ongoing sea level rise, and that melt is accelerating. If the landmass were to lose all of its ice, it would raise global sea level by an alarming 24 feet. Even with current warming, that’s not set to happen right away. Likely it would take hundreds to thousands of years for the island to lose all of its ice mass. But still, less ice on Greenland means much, much less land above water elsewhere.
For millennia, humans have seen inexplicable things in the sky. Some have been beautiful, some have been terrifying, and some — like auroras and solar eclipses before they were understood scientifically — have been both. Today’s aircraft, balloons, drones, satellites and more only increase the chances of spotting something confounding overhead.
In the United States, unidentified flying objects, or UFOs, came into the national spotlight in the late 1940s and early ’50s. A series of incidents, including a supposedly crashed alien spaceship near Roswell, N.M., generated something of an American obsession. The Roswell UFO turned out to be part of a classified program, the remnants of a balloon monitoring the atmosphere for signs of clandestine Russian nuclear tests. But it and other reported sightings prompted the U.S. government to launch various projects and panels to investigate such claims, as Science News reported in 1966 (SN: 10/22/66), as well as kicking off hobby groups and conspiracy theories.
In the decades since, UFOs have often come to be dismissed by scientists as the province of wackos and thus unworthy of study. The term UFO has a smirk factor to it, says Iain Boyd, an aerospace engineer at the University of Colorado Boulder and director of the school’s Center for National Security Initiatives.
But government agencies and officials are trying to change that attitude. Among the biggest concerns is that the stigma associated with reporting a sighting has the side effect of stifling reports from pilots or citizens who might have valuable information about potential threats in U.S. air space — such as the Chinese spy balloon that traversed North America and made headlines last year.
“If there’s something interfering with flights, people or cargo, that’s a problem,” Boyd says.
To help reduce the stigma, many serious investigators now refer to UFOs as “unidentified anomalous phenomena,” or UAPs, coined by the U.S. Department of Defense in 2022. “The term UAP brings science to the issue,” Boyd says. It also rightly broadens the view to include natural atmospheric phenomena as well as things outside the atmosphere, such as satellites and particularly bright planets such as Venus.

Investigators of all types have a lot of questions about UAPs that they believe deserve serious scientific scrutiny: Which UAPs are something real and which are merely artifacts of the sensors that detect them? If real, which may be a threat to aviation? A threat to national security? Do they point to some unknown natural phenomena?
Answers may be forthcoming. In June 2022, NASA announced an independent study to determine how the agency could lend its scientific expertise to the study of UAPs. Meanwhile, military and commercial pilots have felt more comfortable making reports and even providing videos taken during close encounters. Some of those reports were discussed as part of congressional hearings in 2022 and 2023, which were covered widely by the media and in part focused on more government transparency (SN: 5/19/22). Those were the first open hearings since the mid-1960s.
Americans for Safe Aerospace, an advocacy organization with a focus on UAPs, supports legislation that would help provide a way for pilots to confidentially report potential sightings to the government.
And government agencies increasingly recognize publicly that strange phenomena in the skies are worthy of attention — whether the phenomena are signs of aliens or not. In 2022, the Pentagon established the All-domain Anomaly Resolution Office to serve as a clearinghouse for government reports of UAPs and for analysts determining if UAPs pose threats. The National UFO Reporting Center, a nonprofit established in 1974, and other organizations continue to collate reports from the public.
By bringing UAPs into the realm of science, the hope is to make the unexplained explainable.
Where do UAP sightings occur?
Since its founding, the National UFO Reporting Center has kept a database of UAP sightings, including past and recent incidents reported through its telephone hotline, the mail and online. The database includes almost 123,000 sightings in the United States from June 1930 through June 2022. It’s a trove of data that few if any peer-reviewed scientific studies have used, says Richard Medina, a geographer at the University of Utah in Salt Lake City.
For a study reported in 2023, Medina and colleagues scoured the database to see if they could identify which factors, if any, might affect the number of sightings in a particular area. They focused on the almost 99,000 reports, or about 80 percent of the total, that came from the continental United States from 2001 through 2020. They stuck to the continental United States because tree cover was a factor they were studying, and detailed maps of forested land aren’t available for Alaska’s interior.
First, the researchers calculated the number of UAP sightings that occurred in each county in the Lower 48 states for the 20-year period. Then, they tried to correlate the number of sightings per 10,000 people that lived in each county with environmental factors.
In their sights
An analysis of nearly 99,000 reported UAP sightings pinpointed U.S. counties with a particularly high number of reports per 10,000 people (reddish counties), a low number of reports (blues) and an average number (white). One factor that appears to boost the number of UAP sightings is proximity to an airport or military installation, a hint that aircraft may account for many UAPs.

As expected, UAP sightings weren’t as frequent in counties with a lot of tree cover and large amounts of nighttime light pollution, the researchers reported in Scientific Reports. Average cloud cover didn’t seem to affect the number of sightings one way or another — but maybe that’s because the team looked at average cloud cover over the course of the year, not the amount of cloud cover at the time of the sighting, Medina suggests.
What did boost the number of sightings substantially was proximity to airports or military installations. Although this analysis doesn’t specifically say that many UAPs in such areas can be attributed to aircraft associated with those facilities, the data are suggestive, Medina notes. At such sites, aircraft are likely to be closer to the ground and more visible than at other places, he adds.
And many of those aircraft could have been classified or experimental craft, according to a report issued earlier this year by the All-domain Anomaly Resolution Office. After undertaking an analysis of reports made to or by the government since 1945, that office found that many sightings could be attributed to never-before-seen craft such as rockets, drones or aircraft incorporating stealth technologies. The analysis found no evidence that any UAPs were signs of extraterrestrials and no evidence that the U.S. government ever had access to alien technology.
A second report, with new analyses focused on more recent sightings, will be released later this year.
What are UAPs?
The task of pinning down the sources of UAPs has become easier thanks to the ever-growing analytical prowess of computers and advanced visualization tools. “What used to take months of analysis before can now be done in just a few minutes,” says Mick West, a retired software engineer in Sacramento, Calif., who runs the website Metabunk.org, where people can post and discuss UAPs and other unusual phenomena.
Take, for instance, an enigmatic sighting of lights in the sky over the Great Plains one night early in 2023. Video of the UAP taken by a commercial pilot in flight caused a stir when it was posted online soon after the sighting, West says.
Whoever posted the video didn’t include specifics about the sighting, other than to say it was taken somewhere over the central United States on a particular date. A pattern of lights on the ground, which turned out to be warning lights atop turbines in a large wind farm, helped investigators on Metabunk locate the plane as somewhere in western Oklahoma.
Certain details about the sighting, such as flashes of lightning on the distant horizon, wouldn’t have occurred on the supposed date of the video, West notes. Using public meteorological databases about the times, dates and locations where lightning strikes occur, the Metabunk crew figured out the video actually had been taken a few days earlier than reported. The date, in turn, helped the group figure out which flight the video was taken from.
Not an alien
In 2023, a commercial airline pilot took a video of a UAP (white arrows, top left), which was posted to the website Metabunk.org. Using the pattern of lights on the ground, Metabunk sleuths determined the UAP was filmed above Oklahoma. Further investigation revealed the date of the flight and flight path (yellow line, right). Computer simulations of the sky helped pinpoint Starlink internet satellites as the source of the mystery lights (bottom left).
Mick West
Then, knowing the date, time and precise coordinates, West and collaborators used computer simulations to re-create what the sky would have looked like in the direction where the UAP was seen. The mystery lights were actually a cluster of Starlink satellites reflecting sunlight from below the horizon as they swooped across the sky. With the first batch launched in 2019, Starlink satellites now circle Earth in the thousands, providing internet service for locales worldwide (SN: 3/12/20). Their movements and patterns in the sky “are still a mystery to some pilots,” West says.
West suggests that people are often too quick to jump from “I saw some lights in the sky” to “Aliens!” With so many possibilities for what UAPs might be — optical illusions, meteorological phenomena and aviation-related sightings, plus more — the experience generally turns out to be more mundane than observers imagine, West says.
“We’re not really looking for aliens,” he explains. “We’re looking to explain what people are seeing.”
The study of UAPs needs more and better data
Good data are key to deciphering UAPs, but they’re often in short supply. Although many reports by pilots include images taken by onboard sensors or with handheld video cameras, those instruments often aren’t sophisticated enough to capture the necessary details. The same is true for sightings reported from the ground, where the specifics of a presumed object’s direction and speed as well as general environmental conditions are often lacking.
By contrast, NASA has a wealth of data from satellites that monitor Earth. Though they don’t have the resolution to spot relatively small objects the size of most UAPs, the satellites are poised to play a supporting role, says astrophysicist Thomas Zurbuchen. Now at ETH Zurich, he’s a former associate administrator of NASA’s Science Mission Directorate. NASA satellites could be key in providing details on any environmental conditions that may coincide with UAPs, according to the NASA team’s report, released in September 2023. Data collected by commercial satellites can play a similar role.
Gathering and analyzing data is a good way to address what UAPs are, Zurbuchen says. “We should be excited about things we don’t understand, whether they’re natural phenomena, balloons or other things,” he says. “We currently don’t understand what’s flying in our airspace, not to the level that’s needed.”
Boyd also emphasizes the need for better data. The sensors typically used on planes today “weren’t designed to detect UAPs, and the signals that we do pick up are sometimes hard to interpret,” he says. Yet getting the right data may prove challenging and expensive. Integrating new types of sensors into the already-complicated electronic systems of military and commercial aircraft would be something of a “needle-in-a-haystack type of endeavor,” Boyd says. “There are more than 100,000 flights per day; how many have actually seen anything?”
Explained anomalous phenomena
Although many UAPs remain puzzling, experts have identified some common sources. Saucer-shaped lenticular clouds, birds in flight, thermal fluctuations in the atmosphere and other natural phenomena explain some sightings, as do celestial objects like Venus. And while no alien technology has been linked to UAPs, human tech has, including weather balloons, satellites, drones, airborne trash and military aircraft. Last year, a particularly spooky spiral in the sky over northwestern Canada turned out to be vapor from unspent fuel released from a SpaceX rocket.

Perhaps ground-based instruments are the way to go. Several research teams are developing suites of instruments that can observe a broad range of characteristics and be deployed to sites where UAPs are frequently seen. Some of these packages could be ready to deploy late this year.
Wes Watters, a planetary scientist at Wellesley College in Massachusetts, is on one team now developing such instrument packages. The observatories are intended to “determine whether there are measurable phenomena in or near Earth’s atmosphere that can be confidently classified as scientific anomalies,” he and colleagues proposed in the March 2023 Journal of Astronomical Instrumentation. Or, in simpler terms, “to figure out what’s normal versus what’s not normal,” he explains.
Designing such observatories is complicated by the fact that not all UAPs are the same. But previous fieldwork, as well as the observations made by people during UAP sightings, is a rich source of information about what measurements could be useful, Watters says. Besides sensors for detecting and characterizing a UAP itself, instrument packages will collect weather data, which could help researchers interpret the other measurements.
Watters and colleagues are developing three styles of instrument packages as part of the Galileo Project. Led by Harvard University astronomer Avi Loeb, the project seeks to bring the search for signs of extraterrestrial technologies into mainstream scientific research.
The most elaborate instrument package will sport arrays of wide-field cameras for targeting aerial objects and triangulating their positions; narrow-field cameras for tracking objects across the sky; radio antennas and receivers; microphones that can detect sound across a wide range of wavelengths; and computers that can integrate, process and analyze data. These weather-resistant systems will function autonomously 24/7 and be deployed at sites with electrical power and internet connectivity.
These observatories will likely cost around $250,000 each and be deployed to at least three sites for up to five years.
A second, more portable option will be designed for rapid deployment for up to two weeks to sites that don’t have access to electrical power or internet. Each costing about $25,000, these simpler packages will be monitored daily, with data recorded and then processed later and elsewhere. The instruments won’t necessarily be weatherized, restricting their operation to mild-weather locales.
The third, simplest and least expensive package will host low-end, consumer-grade sensors and instruments, Watters says. They’ll be easy to maintain, monitor the sky within a radius of five kilometers and operate continuously for up to a year, relying on solar and battery power if need be. Groups of these packages can be networked together to cover a broad region. Each package will probably cost about $2,500.
With these sorts of instrument packages — and open minds, Watters suggests — researchers are bound to make new discoveries. “It’s impossible to make sense of these phenomena until we collect the right kinds of data,” he says.
In their 2023 report, Watters and colleagues noted that though several teams are developing or using instrument packages, none have yet reported detection of UAPs in peer-reviewed papers. The Galileo Project, including Watters’ team’s research, is funded by private donations, including a recently received $575,000 grant to establish and monitor a ground-based observatory somewhere in the Pittsburgh area.
The goal is not to explain away UAPs, Watters says. Instead, he notes, “we’re about identifying and characterizing what they are or might be.”

A retired primary school caretaker says he's kept his encounter with a UFO secret for five decades.
Gordon Mackerracher said he was 17-years-old in 1974 when he spotted a brown, caravan-sized metallic conical structure above a rural lane in West Lothian, Scotland.
The now 67-year-old remembers watching the aircraft as he hurriedly made his way to a phone box on Langton Road to call air traffic control at Edinburgh Airport.
He claims staff at the control tower explained no aircraft had entered or left the surrounding airspace in the past hour.
Gordon said he remained tight-lipped about his experience for so long because did not want to be branded as an “idiot” or associated as someone who saw “space people''.

He said: “I never told a soul. I was too scared because I did not want to be classed as an idiot, so I just kept quiet about it when I got back to my parents. Not once did I think my mind was playing tricks on me as I knew exactly what I saw. I had no interest in UFOs at the time or even thought about them or anything like that.
His experience stayed in the family with his son Ross also learning of what happened 50 years ago.
Despite his concerns around other people’s perceptions, Gordon grew in confidence after reading Arthur C Clarke’s ‘Mysterious World’ which contained a near identical drawing of a UFO craft that was spotted by a Yorkshireman around the same time.
Describing the night he say the object in 1974, Gordon said he left the cottage of a girl he was dating to travel down a road which connects the villages of Kirknewton and East Calder.
Gordon said he remained tight lipped about his experience because he did not want to be branded as an 'idiot' or associated as someone who saw 'space people'(Image: Callum Moffat)
He said: “I don’t know why but I looked to my left and in the sky above me was this brown conical craft travelling in total silence.
“I could see the moonlight shining off it. It was funny, as I don’t remember being scared when I watched it, although it is possible I was at the time.
“I headed to the phone box on Langton Road which was about a 20 minute walk and phoned the control tower at the airport. I told them I saw a conical object flying in the sky that was completely silent.
“They went away to check and when the guy came back he told me that nothing had taken off or arrived at Edinburgh in the past hour. He said their radar did not capture anything during that time either.
“At first I thought it was maybe circling round to land at Edinburgh airport but obviously not. I just told the controller that it didn’t matter and headed home.”
The first time he opened up was several years later to his wife Margaret when they were watching a show that mentioned extraterrestrial encounters.
“Not once did I think my mind was playing tricks on me as I knew exactly what I saw. I had no interest in UFOs at the time or even thought about them or anything like that.
“The first time I mentioned it was after I got married and something came on TV about UFOs. I told my wife about the encounter and she just said ok. I later told my son about it as well. Neither of them are really believers or non-believers, it never really comes up between us.''
China’s super-secret space plane spotted above Europe
China’s super-secret space plane spotted above Europe
Story by Andrew Paul
So little is known about Shenlong, China’s ultra-secret, reusable space plane that there aren’t even publicly verifiable photos of the experimental aircraft. But that doesn’t mean knowledgeable astronomy enthusiasts can’t catch glimpses of the vehicle as it orbits Earth, as was recently the case for Felix Schöfbänker in Upper Austria. Based on his July 30 images first highlighted by Space.com, Schöfbänker theorizes he possibly identified a pair of previously unknown features on Shenlong’s underside—potentially a pair of solar panels that help power the craft.

Space planes like Shenlong are designed for multi-year, uncrewed orbital missions after hitching a ride aboard a rocket. Upon mission completion, however, the vehicles are capable of returning to Earth and landing on runways similar to conventional aircraft. China’s mysterious robotic vehicle has completed at least two confirmed missions since 2020, the second of which lasted 276 consecutive days in orbit above Earth. During that excursion, Shenlong deployed at least one free-flying object that experts believe may have been either a small satellite or external craft designed to monitor the plane itself. Its current mission began after launching from a Chinese space agency facility in the Gobi Desert on December 14, 2023. Since then it has released at least seven confirmed objects of unknown purpose into orbit. Thanks to the new images, it seems that it might receive at least some of its power sources through solar panel arrays.
“I am not really sure if they are solar panels or some other features like an antenna or something of that nature,” he added on Monday.
Altitude, time, and angle details during Shenlong’s sighting on July 30, 2024.
Additional information inferred from the data includes apparent confirmation that the space plane recently lowered its orbit down to about 217 miles above Earth, and that it does appear to measure somewhere within its previously estimated 30-foot length. Although its wings are not visible in the grainy imagery, it is still believed that Shenlong’s wingspan is at least wide enough to necessitate small cutouts in China’s Long March 2F rocket used to deliver it into orbit.
Shenlong isn’t the only experimental space plane currently conducting secretive missions above Earth. The US Space Force’s X-37B, built by Boeing and slightly smaller China’s aircraft, has been working on its own endeavors since its latest launch aboard a SpaceX Falcon Heavy rocket on December 28, 2023. Two Boeing X-37 variants are believed to exist, and have completed six previous missions so far—its last excursion lasting a total of 909 days in orbit.

Mars Once Hosted Lake Larger than Any on Earth: Lake Eridania
This new image from the High Resolution Stereo Camera (HRSC) onboard ESA’s Mars Express spacecraft shows Caralis Chaos, broken-down and dried-up remnants of a vast ancient Martian lake named Lake Eridania.
This image from ESA’s Mars Express shows Caralis Chaos, a Martian region where copious water is thought to have once existed in the form of an ancient lake known as Lake Eridania.

Lake Eridania once held more water than all other Martian lakes combined and covered an area of over a million km2.
The lake was larger than any known lake on Earth, containing enough water to fill the Caspian Sea nearly three times over.
It likely existed around 3.7 billion years ago, first as one large body of water and later as a series of smaller isolated lakes as it began to dry out.
Eventually Lake Eridania disappeared completely, along with the rest of the water on the Red Planet.
“The lower-left part of the frame features the remains of an old lakebed,” the Mars Express researchers said.
This oblique perspective view was generated from the digital terrain model and the nadir and colour channels of the High Resolution Stereo Camera on ESA’s Mars Express. It shows a region of Mars known as Caralis Chaos, where copious water is thought to have once existed in the form of an ancient lake.

This colour-coded topographic image shows a region of Mars known as Caralis Chaos, where copious water is thought to have once existed in the form of an ancient lake. It was created from data collected by ESA’s Mars Express on 1 January 2024 (orbit 25235) and is based on a digital terrain model of the region, from which the topography of the landscape can be derived. Lower parts of the surface are shown in blues and purples, while higher altitude regions show up in whites and reds, as indicated on the scale to the top right. North is to the right. The ground resolution is approximately 15 m/pixel and the image is centred at about 38°S/177°E.

This tan-colored slice of ground is smoother to the left and becomes covered in small hills and mounds to the right. Wriggly, uneven ridges cut horizontally across the frame, while two prominent fault lines cut down vertically on the left and right. Large and small craters are peppered across the terrain. The worn-away boundaries of a once-colossal lakebed can be seen curving up and away from the bottom-center to the top right; this skirts around the largest crater seen here, which sits in the middle of the picture encircled by rough, irregular valleys and channels.

“The boundaries of this bed can be seen curving up and away from the center of the frame, skirting around the large central crater.”
“The old lakebed is now filled with lots of raised mounds, thought to have formed as ancient Martian winds swept dust across the planet.”
“This dust was later covered and altered by water, before drying out again and breaking apart.”
Alongside water, there are clear signs of volcanism at play in and around this region, known as Caralis Chaos.
“Two long cracks run horizontally through this image, cross-cutting both the aforementioned lakebed and the smoother ground to the top,” the scientists said.
“These are known as the Sirenum Fossae faults, and formed as Mars’ Tharsis region — home to the largest volcanoes in the Solar System — rose up and put immense stress on the Martian crust.”
“Volcanic stress is also to blame for the many wrinkle ridges found here.”
“These appear as wriggly lines weaving across the frame vertically.”
“Wrinkle ridges are common on volcanic plains, forming as new lava sheets are compressed while still soft and elastic, causing them to buckle and deform.”
“The impact craters here, created as space rocks collided with Mars, are also fascinating.”

Een team onderzoekers liet zich inspireren door de neushoornkever om een piepkleine robot te maken door enkele van zijn meest bijzondere vliegeigenschappen na te bootsen.
De passieve spanwijdte van de neushoornkever
In de natuur is er een insect, de neushoornkever, wiens vlucht een bijzonderheid heeft die we als “speciaal” kunnen omschrijven: hij kan zijn achtervleugels uitklappen en sluiten zonder de hulp van spieren. Een eigenschap die alleen dit beestje bezit en die de aandacht heeft getrokken van een internationaal team van onderzoekers, dat een micro-robot wilde maken die net als de neushoornkever met zijn vleugels kan klapperen en dezelfde passieve opening van de vleugels kan imiteren.
Het doel? Aantonen dat deze unieke manier een gecontroleerd vluchtpatroon met een hoge stabiliteit kan produceren. Om het project tot leven te brengen, observeerden de onderzoekers Allomyrina dichotoma insecten tijdens hun vlucht en filmden ze hun bewegingen in slow motion met speciale camera's die op hoge snelheid werden gesynchroniseerd. Vervolgens creëerden ze de minirobot die met dezelfde techniek zijn vleugels kon openen en intrekken.
De micro-robot bootst de vliegtechniek van de gevleugelde neushoorn na
nature
Door het onderzoek ontdekte het team dat de neushoornkever elastische energie en de kracht van de puls gebruikt om zijn achtervleugels passief uit te schuiven tijdens de vlucht, terwijl hij zijn harde en robuuste voorvleugels, dekschilden genoemd, gebruikt in plaats van zijn borstspieren om ze in te trekken. Op basis van deze informatie bootsten de onderzoekers dezelfde modus operandi na in de micro-robot, waarbij ze niet alleen met succes de vleugelverlenging tijdens het opstijgen nabootsten, maar ook de stationaire vlucht in de lucht en het intrekken van de vleugels tijdens de landing of in het zicht van een botsing.
Deze resultaten verrijken volgens het team onze kennis over de vliegmodus van gevleugelde insecten en maken de weg vrij voor de creatie van robots van microformaat. Voor deze levende wezens zijn vleugels essentieel voor een groot aantal vitale activiteiten, zoals het zoeken naar voedsel en het ontsnappen aan roofdieren. Deze instrumenten zijn zeer delicaat, maar tegelijkertijd van fundamenteel belang en moeten daarom worden beschermd: om dit te bereiken vouwen talrijke insecten ze naar het lichaam toe, om zo mogelijke schade te voorkomen wanneer er niet wordt gevlogen.
De middelpuntvliedende kracht van de vleugels is het geheim van de gevleugelde neushoorn
Eerder onderzoek ging ervan uit dat het open- en dichtklappen van de vleugels bij gevleugelde neushoorns door de spieren werd geregeld, maar dit was nog nooit aangetoond. In feite opent deze kever zijn vleugels in twee verschillende momenten: eerst worden de dekschilden volledig opgetild en onmiddellijk daarna is er een gedeeltelijke opening van de achtervleugels, die lijkt te worden bepaald door de opgeslagen elastische energie in plaats van door spiergebruik.
Op een tweede moment klappen de vier vleugels synchroon met een volledige opening van de achtervleugels. Volgens het team bevordert de centrifugale kracht van de slag de passieve opening van de achtervleugels. De micro-robot valideerde deze overwegingen en was uitgerust met een elastische pees die het sluiten en openen van de vleugels vergemakkelijkt en geactiveerd wordt tijdens het slaan van de vleugels. Dankzij dit model kon worden aangetoond dat de centrifugale kracht die alleen al door de vleugelslag wordt opgewekt, voldoende is om de vleugels op te tillen.

For earlya decade, hundreds of tiny magnetic spheres shed by an extraterrestrial visitor lay deep beneath the Pacific Ocean. Now, the minute pellets have been dredged up by a scientific expedition — and they're fueling a media frenzy that some scientists feel is unearned.

In 2014, a fireball blazed across the sky above Papua New Guinea, shedding debris as it passed. A U.S. government sensor stationed nearby measured its speed at more than 110,000 mph (177,000 km/h), and NASA's Center for Near-Earth Object Studies (CNEOS) detected its fall. The meteorite splashed down in the ocean about 53 miles (85 kilometers) offshore.
Avi Loeb, an astrophysicist at Harvard University, is on a quest to find it. Based on its extreme speed and trajectory upon entry into Earth's atmosphere, Loeb believes the object, which he dubbed Interstellar Meteor 1 (IM1), is a relic from another star system. He also thinks it might potentially harbor alien "technosignatures" — traces of technology crafted by nonhuman entities — according to an interview Loeb gave with the Daily Beast.
This is not the first time Loeb has hypothesized that our solar system has been visited by alien technology. Five years ago, he and fellow Harvard researcher Shmuel Bialy proposed that the weird interstellar object 'Oumuamua, which whizzed through our solar system in late 2017, was an autonomous alien probe similar to a light sail. Theirpaper on the object garnered a flurry of media attention, as well as both pushback and praise from the larger scientific community.

Now, backed by funding from crypto multimillionaire Charles Hoskinson, Loeb is leading an expedition in the Pacific Ocean to recover IM1. So far, the crew has pulled up more than 50 magnetic spherules — minuscule orbs made of iron, magnesium and titanium — that may be pieces of the meteor. In a recent blog post, Loeb described these spherules as "anomalous" — presumably due to their low nickel content, a common ingredient in meteorites.
"This has been the most thrilling experience in my scientific career," Loeb said of the expedition in a recent interview with Motherboard.
However, many scientists harbor doubts about the spherules' origin. In fact, they say these particular pellets might not be associated with the 2014 fireball at all.
"It's been known for a century that if you take a magnetic rake and run it over the ocean floor, you will pull up extraterrestrial spherules," Peter Brown, a meteorite specialist at the University of Western Ontario in Canada, told Live Science. Such debris has accumulated worldwide on the seafloor over millions of years from meteors dropping tiny bits of molten metal as they pass overhead, Brown added. Factoring in shifting ocean currents and sedimentary movements, "it essentially would be impossible to say that this particular spherule comes from a particular event."
Harvard professor Avi Loeb said his team of scientists have determined that these fragments from a meteor that landed in the waters off of Papua New Guinea in 2014 are indeed interstellar in origin.
Brown also recently co-authored a paper calling into question IM1's interstellar pedigree. The claim that the meteor came from outside our solar system is based on its ridiculous speed upon entering our atmosphere. However, Brown said, "particularly at higher speeds, the U.S. government sensors tend to overestimate speeds." A lower speed would also account for the object's unusual brightness profile, which didn't match what would be expected for a metallic meteor moving at over 100,000 mph (160,000 km/h), Brown said.
Of course, this doesn't mean the meteorite isn't from another star system — just that it doesn't have to be. To date, there have been no confirmed interstellar meteorite impacts on Earth, though Brown himself has spent 20 years searching for one.
As for the possibility that this is evidence of extraterrestrial technology, most of the scientific community is skeptical. "That would be an extremely cool result," Brown said. "But I don't see any evidence that would necessarily back you into such an extreme hypothesis."

Coast to Coast AM: Trading Antarctica for Alien Technology: The Untold Story
Coast to Coast AM: Trading Antarctica for Alien Technology: The Untold Story
The radio show “Coast to Coast AM,” known for its intriguing discussions on paranormal phenomena, recently featured an episode exploring the tantalizing possibility of a secret agreement between humans and extraterrestrials. The episode, titled “They Gave Us Alien Tech, We Gave Them Antarctica,” delved into the fascinating claims of Len Casten, a former U.S. Air Force member, who has devoted much of his life to researching UFO phenomena.
The Encounter That Sparked a Lifelong Quest
Len Casten’s journey into the world of UFO research began with a personal encounter. As a young man in the U.S. Air Force, he witnessed a mysterious craft, glowing green and gold, silently soaring across the sky. This sighting, corroborated by radar reports of unidentified flying objects, planted the seeds of curiosity in Casten’s mind. Although it would take years before he fully grasped the significance of his experience, it ultimately led him to join the National Investigations Committee on Aerial Phenomena (NICAP) and pursue a lifelong interest in extraterrestrial phenomena.
Alien Involvement in World War II
One of the most controversial topics discussed on the show was the alleged involvement of aliens in World War II. According to Casten, Hitler’s development of advanced weaponry, such as anti-gravity aircraft, was not achieved solely by German scientists. Instead, he suggests that the Nazis received extraterrestrial assistance, potentially from a malevolent race known as the Reptilians. This alliance, he argues, was aimed at world domination, with the extraterrestrials seeking to use the fascist movement as pawns in a larger cosmic game.
Operation Highjump: The Battle for Antarctica
The episode also covered Operation Highjump, a U.S. military expedition to Antarctica in 1946. Officially described as a research mission, Casten claims it was a full-scale military invasion intended to destroy a secret Nazi base. This base, reportedly discovered by British intelligence, was believed to house remnants of the Nazi regime, including advanced technologies developed with extraterrestrial aid. However, the mission allegedly ended in failure when the fleet was confronted by flying saucers, forcing a hasty retreat.
Eisenhower’s Alleged Treaty with Aliens
A significant portion of the episode focused on President Dwight Eisenhower’s purported meetings with extraterrestrial beings in 1954. The first encounter was with the Nordics, a group of aliens who offered to share advanced technology and spiritual wisdom in exchange for the abandonment of nuclear weapons. When this offer was declined, a second meeting occurred with the Grays, resulting in the signing of a controversial treaty. This agreement allegedly allowed the Grays to abduct humans for experimentation in exchange for sharing advanced technology, including weaponry.
The Hybridization Agenda
One of the most unsettling aspects of the discussion was the Grays’ alleged hybridization program. Casten explained that the Grays, facing the decline of their race, aimed to revitalize themselves through genetic manipulation, creating hybrids with human DNA. While some theorists, like Dr. David Jacobs, view this as a prelude to a future takeover, others speculate that it could be a strategy to ensure survival in the face of an impending global catastrophe.
Presidential Awareness and Secrecy
The show also touched upon the knowledge and involvement of various U.S. presidents in extraterrestrial affairs. From Truman to Bush Sr., each president reportedly had different levels of awareness regarding UFOs and alien interactions. The ongoing secrecy surrounding these topics is often attributed to the embarrassment and potential public panic that would arise from acknowledging such agreements and activities.
Time Travel and Dimensional Theories
Adding another layer of complexity, the episode explored theories suggesting that some extraterrestrials might be time travelers or multidimensional beings. These ideas challenge traditional notions of space travel, proposing instead that aliens may traverse time or dimensions to reach Earth, bringing with them technology and knowledge far beyond our current understanding.
The Cosmic Struggle: Good vs. Evil Alien Races
Throughout the episode, a recurring theme was the cosmic struggle between benevolent and malevolent alien races. The discussion highlighted the potential for humans to align with more advanced and benevolent extraterrestrial civilizations, which could aid in creating a utopian society on Earth. However, this vision is hindered by the alleged alliances between certain military factions and tyrannical alien races.
Crop Circles and Ancient Aliens
The episode also delved into the mystery of crop circles and their possible extraterrestrial origins. While some crop formations are believed to be human-made, others exhibit complexities that suggest non-human creation. This topic ties into broader theories about ancient aliens and their influence on human civilizations, including the construction of monumental structures like the pyramids.
As the episode concluded, the hosts speculated on the potential for future disclosure of extraterrestrial presence and interactions. While official government acknowledgment seems unlikely, the possibility remains that extraterrestrials themselves might reveal their existence to humanity. Until then, the mysteries surrounding UFOs, alien technology, and secret agreements continue to captivate and intrigue audiences worldwide.
There are already dozens of claims in favor of extraterrestrial visitation. Today, numerous astronauts and government officials support the UAP phenomena, and some are highly positive that they could have an alien origin. The Honorable Paul Hellyer (1923-2021), former Canadian Minister of Defense said extraterrestrials have been visiting our planet for thousands of years and it is likely that at least two of them are working with the U.S. government and sharing their highly-advanced technologies with humans.
In the 1960s, Paul Hellyer, a high-ranking official during the Cold War, asserted that he had discovered with certainty about the existence of aliens while serving in the military. He said that people from other worlds had been coming to Earth for a very long time. He insisted that a lot of the stuff that makes up our high-tech gadgetry had been gifted to us by overly-advanced ETs.
Hellyer had long expressed his views on extraterrestrials in public. He testified at the Citizen Hearing on Disclosure in May 2013 in Washington, DC. Five former members of U.S. Congress and one former U.S. senator listened to more than thirty hours of testimony from government officials, military personnel, researchers, and witnesses.
Huffington Post Canada described that, as part of his testimony, Hellyer stated that “aliens are living among us and that it is likely at least two of them are working with the U.S. government.” More specifically, Hellyer announced that at least four species of extraterrestrials had been visiting Earth for thousands of years. According to Huffington Post Canada, he also stated that some extraterrestrials originate from the “Zeta Reticuli, the Pleiades, Orion, Andromeda, and Altair star systems” and “may have different agendas.”
He first spoke openly about his belief governments are covering up an alien presence back in 2005, saying UFOs are as plentiful in our sky as airplanes. “Much of the media won’t touch it, so you just have to keep working away at it and we will get a critical mass and one day they will say Mr. President or Mr. Prime Minister, we want the truth and we want it now because it affects our lives.”
In 2013, Hellyer appeared on the RT interview show SophieCo with Sophie Shevardnadze to discuss extraterrestrials and UFOs. Shevardnadze asked Hellyer, “Why do you say that UFOs are as real as airplanes flying over our heads?” Hellyer replied, “Because I know that they are. As a matter of fact, they’ve been visiting our planet for thousands of years.” He further stated military action had brought down UFOs, and humans had adapted alien technology for use on Earth.

He said: “As far as technology is concerned, they are light years ahead of us, and we have learned a lot of things from them. A lot of the things we use today we got from them, you know – led lights and microchips and Kevlar vests and all sorts things that we got from their technology and we could get a lot more too, especially in the fields of medicine and agriculture if we would go about it peacefully. But, I think, maybe some of our people are more interested in getting the military technology, and I think that’s wrong-headed, and that’s one of the things that we are going to have to change, because we’re going to have to work together, all of us, everywhere on the planet.”

Shevardnadze asked: “Have you ever had your own encounter with aliens?” Hellyer replied: “Not encounter with aliens, no. I’ve seen a UFO, about 120 miles north of Toronto, over Lake Muskoka, where I have a cottage. Two years ago, at Thanksgiving, which is October, [my wife?] said that she wanted to go out and look at the stars, so… I’m not much of a night man… but I put on my cap and went out with her and she looked into the eastern sky and said, ‘There’s a star,’ and I turned the other way and said, ‘Oh, there’s a much brighter one over here,’ and she looked there and we watched it until our necks almost broke for about 20 minutes, and it was definitely a UFO because it could change position in the sky by three or four degrees in three or four seconds.”
Shevardnadze further asked Hellyer if shooting down those UFOs was risking an interstellar war, and, if so, “should we be creating a Star Wars force to defend ourselves from possible invasion or something like that?”
Hellyer said: “I think it’s a possibility, but it’s a possibility especially if we shoot down every UFO that comes into our airspace without asking who they are and what they want. Right from the beginning, we started scrambling planes, trying to shoot them down, but their technology was superior enough that we weren’t able to get away with it, certainly not for a long while.”
He continued: “During that period of time they could have taken us over without any trouble if they wanted to, so I think, rather than developing our own Star Wars to protect ourselves against them, we should work with the benign species that are of a vast majority and work together, and rely largely on them, of course, and cooperate, so that we would be contributing something at the same time; I don’t think there’s any point in us developing a galactic force that would tempt us to ride on our own and get into mischief, which is one of the things that some of them are concerned about.”
On countering physicist Stephen Hawking’s assertion that any alien visitors to Earth would likely be malevolent, Hellyer argued that not only have aliens already visited Earth but that they have helped contribute to humanity’s technological progress. He said earthlings owe a lot to their alien friends. “Even that computer screen on your desk,” he said, “can trace its origins to spaceships. Microchips, for example, fiber-optics, they are just two of the many things that allegedly — and probably for real — came from crashed vehicles,” Hellyer added. (Source)
Hellyer was not the only one speaking of a partnership between humans and extraterrestrial intelligence. The former head of the Israeli space security program and retired general Haim Eshed also claimed that a sort of agreement had been made between aliens and the US government to keep silent on their experiments on Earth and secret bases on Mars.
Mr. Eshed said that aliens and “Galactic federation” do exist and have been working with the US and the Israel government for years, but they keep it a secret to avoid mass hysteria. According to him, President Trump was aware of it and has already been in contact with space aliens. He further said that the aliens have been waiting for humans to evolve and reach a certain stage to actually understand space and spaceships. Besides, they signed a contract with humans to do experiments on Earth and also research with them to learn the fabric of the universe.
A potentially revolutionary new technology that could greatly advance optical communications, surveillance, and photonic device isolation has something in common with the most captivating construction design of the ancient world: the pyramid.
Researchers at UCLA have produced a revolutionary new design for diffractive deep neural networks, or D2NNs, that they say significantly enhances unidirectional image magnification and demagnification. Dubbed Pyramid D2NNs, the new design architecture lives up to its name by introducing a pyramid-structured network that offers high-fidelity image formation while reducing refractive features, all by aligning its layers in the same direction of image magnification and demagnification.
What Are Diffractive Deep Neural Networks?
D2NNs are constructed from individual transmissive layers that are optimized through deep learning, allowing them to perform computation almost entirely through the use of optics.
In their recent research, the UCLA team, led by Professor Aydogan Ozcan, worked with a pyramid-shaped diffractive optical network, a design that allowed the team to achieve unidirectional imaging with fewer diffractive degrees of freedom.
The result is a design that helps to ensure high-fidelity image formation, but only in one direction. By contrast, significant image inhibition occurs in the opposite direction, conditions that are key for use with applications where imaging in one direction (i.e., unidirectional imaging) is required. Such fields include defense and security technologies, telecommunications applications, and systems used for privacy protection.

The team was also able to demonstrate modularity and scalability for their novel pyramid-structured system by cascading several P-D2NN modules. This allowed them to achieve even greater magnification or demagnification factors.
The Pyramid Mystery
The pyramid shape has long captivated human minds, and there is arguably no better example of this than the enigmatic pyramids at Giza.
In simple terms, a pyramid is a three-dimensional shape resulting from the construction of triangular faces arising from a polygonal base. Each of the points of the triangular portions meets at the highest point or apex.
This gives rise to a unique shape where weight is evenly distributed, which allowed ancient architects to rely on this design for the construction of some of the largest structures ever built, with the most famous examples comprising the Giza pyramids, monuments that are still impressive by today’s engineering standards, and which have proven their resilience by persisting for thousands of years. Given their enigmatic appearance, the pyramids have also contributed to a number of fringe ideas over the years, involving the mysterious powers the monuments at Giza may possess themselves or purported technologies (many of them pseudoscientific) based on the pyramid shape and powers it allegedly possesses.

For the UCLA team, the pyramid structure offered real-life advantages in that the ascending structure allowed them to scale the layers of the new D2NN in such a way that aligns with the direction of image magnification or demagnification. In other words, the pyramid shape offers a sort of guide that either enlarges or shrinks the image in question in a controlled manner. The result is that high-fidelity imagery is able to pass progress through the network, but only in the desired direction.
During their research, the team also succeeded in experimentally validating the new P-D2NN system by using terahertz (THz) illumination. 3D-printed diffractive layers were tested under continuous-wave THz illumination, producing results that the team says very closely matched earlier numerical simulations.
Applications and Future Prospects
The system is ideal for various applications, including technologies that provide optical isolation for photonic devices and decoupling of transmitters and receivers in telecommunications. In the coming years, the new pyramid-shaped system could also benefit security and even surveillance technologies.
Overall, the team’s P-D2NN architecture represents a considerable advancement in optical imaging technology, which its developers believe could help pave the way toward a range of future innovations and applications. All of which, of course, relies on one of the most iconic and captivating ancient monumental shapes in human history.
The team’s findings were published in the journal Light: Science & Applications on July 31, 2024.

Conspiracy theories have created J. Rod the Alien —an extraterrestrial person— who is said to have been employed by the US government in Area 51.
The J. Rod tales initially surfaced in the 1980s, and several novels and TV series have helped to promote them.
According to these tales, J. Rod is a tall, slender alien with large, almond-shaped eyes. He is said to have been a survivor of a UFO crash in Kingman, Arizona, in 1953.
After the crash, J. Rod was taken to Area 51, where he helped scientists and engineers to reverse engineer the alien technology. He is also said to have shared knowledge about his home planet and the universe with the U.S. government.
A recent documentary on the History Channel renewed interest in the tale and sparked further speculation and conspiracy theories.
According to alien author Preston Dennett, the extraterrestrial “allegedly worked at Area 51 for some years.” He went on, “J Rod’s job was to assist in reverse engineering technology that was reportedly from the 1953 Kingman UFO crash. Giving the technology that we need today. Most of the electronic devices we are using today.”
The stories of J. Rod are based on the accounts of several individuals, including military personnel and civilian contractors who worked at Area 51. These individuals claim to have seen J. Rod with their own eyes and to have spoken with him.
Bill Uhouse, a former Navy pilot who claimed to have researched the UFO that crashed in Kingman, was stationed at Area 51 in the mid-1960s.
In an interview from 2000, he claimed to have had direct communication with J. Rod and stated that the alien “sounded just like you” and “tried to answer questions.” The alien spoke perfect English; not an animatronic android or a CGI, the alien was real.
Dan Burisch, another individual, says he was employed as a microbiologist to care for J. Rod and ensure he stayed well. He said the government made him take tissue samples from the captured alien and claimed they became friends during the two years he worked on the project.
1953 Kingman, Arizona UFO crash
The Kingman UFO crash is one of the “best verified” in the United States, Dennett also claimed.
Conspiracies say the object crashed on May 21, 1953, eight miles northeast of the Kingman Airport in the Arizona desert.
Government officials supposedly sent a team of around 40 scientists to the crash site to investigate, and they allegedly found a UFO.
“The object was described as metallic, 30 feet wide and three and a half feet high, oval-shaped with portholes,” the author said.
“Inside were two to four, four-foot-tall humanoids, deceased according to most sources, with large eyes and wearing metallic suits.”
Engineer Arthur Stancil was allegedly one of the ones who helped recover the UFO and concluded it struck the ground at 1,200 mph but was strangely undamaged.
“The object was not built by anything, obviously, that we know about on Earth,” he said. “It was more like a tear-drop-shaped cigar … like a streamlined cigar.”
What happened to the alien?
The whereabouts of J. Rod are unknown. There is no concrete evidence to support his existence, and experts believe that he is a hoax.
One theory espoused by UFO enthusiasts is that J. Rod is still alive and living in seclusion. Some others suggest that he was eventually released from Area 51 and allowed to return to his home planet.
It is also possible that he remains under the control of the U.S. government, perhaps in a secret facility or on a remote island, some believe.
Another possibility is that J. Rod is deceased. Some accounts suggest that he died while working at Area 51, while others claim that he was killed by the government.
