Stephen Hawking's chilling warning to humanity may be coming true after a renowned scientist claimed a 'hostile' encounter with alien life could be months away. Hawking, the famous theoretical physicist who died in 2018, warned the world that making contact with alien life could end in disaster for the human race. The late professor believed that actively seeking out extraterrestrials would bring on a deadly invasion, similar to how cultures on Earth have wiped out less advanced civilizations in the past. 'The extraterrestrials would probably be far in advance of us, 'Professor Hawking said in 2004. 'The history of advanced...

On November 7, 1492, the Ensisheim meteorite was observed to fall in a wheat field outside the walled town of Ensisheim in then Alsace, Further Austria (now France).It was a stony, triangular-shaped meteorite weighing 127 kilograms. The object can still be seen in Ensisheim's Museum, the sixteenth-century Musée de la Régence.Upon impact, the meteorite created a 1-meter (3 ft 3 in) deep hole. Its fall through the Earth's atmosphere was witnessed at a distance of up to 150 kilometers from where it eventually landed.People living in neighboring areas gathered at the location to raise the meteorite from its impact hole....

Astronomers at MIT, Columbia University, and elsewhere have used NASA’s James Webb Space Telescope to peer through the dust of nearby galaxies and into the aftermath of a black hole’s stellar feast. Credit: NRAO/AUI/NSF/NASA Unlike active galaxies that endlessly devour nearby matter, these black holes remain in slumber, stirring only momentarily to consume an unlucky passing star. Astronomers from MIT, Columbia University, and other institutions have used NASA’s James Webb Space Telescope (JWST) to look through thick layers of dust in nearby galaxies and examine the aftermath of black holes consuming stars. According to a new study published on July...

An enormous, 515-mile-long flash of lightning that crossed at least three states has been named the longest in recorded history in the world. The 2017 “megaflash” stretched from eastern Texas to near Kansas City — a distance that would take at least eight hours by car or 90 minutes by commercial plane, according to the World Meteorological Organization. In comparison, the average bolt of lightning usually measures less than 10 miles, according to the National Weather Service.

Credit: NSF NOIRLab/Int.Gemini Ob et al. / SWNS | The Daily Galaxy --Great Discoveries Channel ========================================================================= A team of astrophysicists has raised concerns about a recently discovered interstellar object named 3I/ATLAS, claiming it may not be a comet at all—but potentially a technological artifact of alien origin. Detected on July 1, the object is moving at an extraordinary speed of over 130,000 mph and is expected to reach its closest point to the Sun—its perihelion—later this year, with an arrival window near Earth projected for late November or early December 2025. Strange Features Hint At Alien Design The study, published...

Explanation: Have you ever watched a lightning storm in awe? You're not alone. Details of what causes lightning are still being researched, but it is known that inside some clouds, internal updrafts cause collisions between ice and snow that slowly separate charges between cloud tops and bottoms. The rapid electrical discharges that are lightning soon result. Lightning usually takes a jagged course, rapidly heating a thin column of air to about three times the surface temperature of the Sun. The resulting shock wave starts supersonically and decays into the loud sound known as thunder. On average, around the world, about...

Sunspots, those mysterious dark patches on the Sun's surface, have been observed by astronomers for thousands of years. Yet, despite centuries of study, no one fully understood why these spots could remain stable for such extended periods. New research, however, has finally cracked the case, revealing that the secret lies in a delicate balance between the Sun's magnetic fields and the pressure of its plasma. Sunspots have been documented since at least 27 B.C., with Chinese astronomers recording the phenomenon long before Galileo peered at the Sun through his telescope. Some historical records even suggest that Greek philosopher Anaxagoras might...

While the study is intriguing, additional observations will be essential to verify or challenge its findings. Astudy analyzing JWST observations of the early universe has uncovered an intriguing mystery: most galaxies appear to be rotating in the same direction. This unexpected pattern, which defies current cosmological models, has led the study's authors to propose a bold possibility: that our universe might exist inside a black hole. The JWST has allowed astronomers to peer back further into the past than any other infrared or optical telescope, seeing infrared light that was emitted by distant galaxies just 300 million years after the...

Two days this summer have been unusually short, with the shortest expected on Aug. 5, leading global timekeepers to consider adding a negative leap second. The Earth's rotation has accelerated in recent decades, leading scientists to consider adding the first ever negative leap second. Earth is spinning so fast that global timekeepers are considering something that's never been done before: adding a negative leap second. So far this year, July 9 and July 22 have been unusually short — by about 1.3 and 1.4 milliseconds, respectively. However, Aug. 5 is expected to be even shorter, losing roughly 1.5 milliseconds, according...

The company claims it has cracked a scalable method to make stable gold from mercury. Ever since the discovery of alchemy, or since humans thought gold was a precious object, a worldwide quest to turn common elements into the yellow metal has been ongoing. Folklore and fables sing praises of humans who went on this quest and those who received such blessings. No such claims have yet stood the test of science, and this could change quite soon. An engineering firm from the United States – Marathon Fusion – has claimed that making gold from mercury is possible, and they...

If you like all the Science NASA has done since 1961, then wave it all goodby. NASA budget cut to the lowest since 1961 - before there was a manned space program. No more Rovers, probes, [ even 99942 Apophis probes cut, https://en.wikipedia.org/wiki/99942_Apophis ]. There are no private entities that can or will pick up the slack. Cuts to Hubble and to Webb will leave them orbiting junk. Coupled with the possible collapse of SpaceX from 47's vengeance feud with Musk, the US will no longer have a space program - civilian or military. These twin disasters in the making...

Could Trump put SpaceX out of business? Will ruining Elon Musk save us "big money?" Don't watch if you are a hard core 47 supporter, lest you be triggered. Excerpt from the video transcript: Elon Musk is on the verge of blowing upall of his companies that he's worked so hard to build with his latest feud with Donald Trump that continues to escalate with every new development with the big beautiful bill. Now that it's passed the Senate, it appears that Elon has temporarily quieted down a little bit on X. But nevertheless, the situation remains very, very tense...

Explanation: Have you ever seen a fireball? In astronomy, a fireball is a very bright meteor -- one at least as bright as Venus and possibly brighter than even a full Moon. Fireballs are rare -- if you see one you are likely to remember it for your whole life. Physically, a fireball is a small rock that originated from an asteroid or comet that typically leaves a fading smoke trail of gas and dust as it shoots through the Earth's atmosphere. It is unlikely that any single large ground strike occurred -- much of the rock likely vaporized as...

On July 28, a plane-sized asteroid, named 2025 OW, is scheduled to pass Earth at a distance of 393,000 miles. While this event has captured public attention, NASA experts are quick to remind us that it’s not as extraordinary as it may seem. In fact, according to NASA specialists, close encounters with asteroids like 2025 OW are routine occurrences in the solar system and pose no threat to Earth. As Ian J. O’Neill, media relations specialist at NASA’s Jet Propulsion Laboratory (JPL), told ABC News, “This is very routine. If there was a threat, you would hear from us. We...

Neptune, too, might have a new companion around. Uranus can pull and push minor bodies around. Image credit: NASA Between the orbits of Saturn and Neptune, there is a population of minor space bodies known as the Centaurs. There could be up to 10 million of them, but they tend to have unstable orbits due to the gravitational influences of the giant planets. Occasionally, some enter a temporary stable orbit, joining one of the planets in a resonance. This is what is believed to have happened between Centaur 2015 OU194 and the planet Uranus, the first ever report of this...

Earth's famous Hubble Telescope has just revealed the first images of a mysterious interstellar object racing through our solar system. Spotted on Monday, Hubble has helped astronomers confirm that the massive, high-speed visitor is a comet from a distant part of the Milky Way galaxy. First spotted in late June, the comet named 3I/ATLAS has been on an 800-million-year journey to reach this solar system. The new images from Hubble captured what appears to be an icy tail that's ejecting rocky material from its 12-mile-long core. Those observations were reinforced by a new study published Tuesday morning which revealed 3I/ATLAS...

I have always been bothered by the seeming perplexity that people have about the fact that we have yet to encounter intelligent life beyond planet Earth. It doesn't seem weird to me at all, even though I suspect life--even intelligent life--is not that uncommon in the universe. Enrico Fermi--a great physicist from the mid-20th century-- expressed the perplexity that many people have in what has come to be known as the "Fermi Paradox." At its most simple, the paradox is this: if the development of intelligent life is even moderately likely, why haven't we seen evidence of intelligent life elsewhere...
