(Phys.org)—When a huge meteor collided with Earth about 2.5 million years ago in the southern Pacific Ocean it not only likely generated a massive tsunami but also may have plunged the world into the Ice Ages, a new study suggests. A team of Australian researchers says that because the Eltanin meteor – which was up to two kilometres across - crashed into deep water, most scientists have not adequately considered either its potential for immediate catastrophic impacts on coastlines around the Pacific rim or its capacity to destabilise the entire planet's climate system. "This is the only known deep-ocean impact...

An enormous impact crater thought to have been created by a meteorite the size of a house smashing into Earth has been discovered in the Antarctic ice sheet. Scientists conducting a routine aerial research flight above East Antarctica noticed a strange ring-like structure in the normally flat and featureless ice. It appeared to be a series of broken 'icebergs' surrounded by a 2km (1.24 miles) wide circular scar, surrounded by a few other smaller circular scars in the ice.

WASHINGTON (AFP) - A meteor's roaring crash into Antarctica -- larger and earlier than the impact that killed the dinosaurs -- caused the biggest mass extinction in Earth's history and likely spawned the Australian continent, scientists said. Ohio State University scientists said the 483-kilometer-wide (300-mile-wide) crater is now hidden more than 1.6 kilometers (one mile) beneath the East Antarctic Ice Sheet. "Gravity measurements that reveal its existence suggest that it could date back about 250 million years -- the time of the Permian-Triassic extinction, when almost all animal life on Earth died out," the university said in a statement Thursday....

A team of researchers with members from Singapore, the U.S., Thailand and Laos has concluded that the impact point of a meteorite that struck the Earth approximately 790,000 years ago lies buried beneath a volcanic field in southern Laos. In their paper published in Proceedings of the National Academy of Sciences, the group outlines four lines of evidence that point to the Bolaven volcanic field as the likely site of the meteorite strike. Prior research has shown that approximately 790,000 years ago, a large meteorite (the largest known young meteorite impact) struck Earth in the Eastern Hemisphere. So great was...

A US Vela Hotel satellite captured the Vela Incident, also known as the South Atlantic Flash on September 22, 1979. The incident was a double flash of light that beamed off Antarctica near the Prince Edward Islands. To date, there is no official account of what caused the double flash leading to several hypotheses being advanced on the probable cause. Some sources claim that the incident was characteristic of a nuclear test while others believe that the flash was as a result of an aging satellite generating electrical signals. Other sources also claim that the lights were as a result...

Large Antarctica meteorite The large meteorite that's been recovered. (Maria Valdes) ******************************************************************* Antarctica has a lot going for it when it comes to meteorite hunting. The dark rocks stand out against the icy landscape. Its dry climate keeps weathering to a minimum. And even when meteorites sink into the ice they are often returned to the surface by the churning of the glaciers. In spite of these ideal conditions, finding sizeable chunks of space rock is rare. A group of researchers have just returned from the ice-covered continent with five new meteorites that include an unusually large specimen. The big...

The preservationist group NatureServe just released a report concluding that some 40% of animal species in the US will go extinct in the near future as a result of climate change. Their predictions may turn out not to be quite accurate, since there are other factors at work that determine which species survive and which go the way of the dodo bird and ivory-billed woodpecker. The analysis the report depends on has been severely criticized for lack of rigor by Canadian and Finnish biostatisticians. Anticipated losses among a small percentage of already dangerously endangered species is applied to the vast...

The bankruptcy of crypto’s marquee lender, Genesis Global Capital, may be one more blow than the industry can withstand, at least in its current form. The list of bull-market stars laid low now includes nearly every major player to have captured the public’s attention by offering market-beating returns for the simple act of depositing tokens. Genesis joins BlockFi, Celsius Network and Voyager Digital among firms whose collapse have left countless clients angry and unlikely to risk more money on their daredevil exploits. Acting as de facto banks, these firms took in assets which they then lent out freely across the...

In July 1968 four pairs of mice were introduced into the Utopian universe. The universe was a 9-foot (2.7 m) square metal pen with 54-inch-high (1.4 m) sides. Each side had four groups of four vertical, wire mesh "tunnels". The "tunnels" gave access to nesting boxes, food hoppers, and water dispensers. There was no shortage of food or water or nesting material. There were no predators. The only adversity was the limit on space. Initially the population grew rapidly, doubling every 55 days. The population reached 620 by day 315, after which the population growth dropped markedly. The last surviving...

Two billion years ago a meteorite 10km in diameter hit the earth about 100km southwest of Johannesburg, creating an enormous impact crater. This area, near Vredefort in the Free State, is now known as the Vredefort Dome... The meteorite, larger than Table Mountain, caused a thousand-megaton blast of energy. The impact would have vaporised about 70 cubic kilometres of rock - and may have increased the earth's oxygen levels to a degree that made the development of multicellular life possible... The original crater, now eroded away, was probably 250 to 300 kilometres in diameter. It was larger than the Sudbury...

The destructive space rock was somewhere between 12.4 and 15.5 miles wide. The largest asteroid ever to hit Earth, which slammed into the planet around 2 billion years ago, may have been even more massive than scientists previously thought. Based on the size of the Vredefort crater, the enormous impact scar left by the gargantuan space rock in what is now South Africa, researchers recently estimated that the epic impactor could have been around twice as wide as the asteroid that wiped out the nonavian dinosaurs. The Vredefort crater, which is located around 75 miles (120 kilometers) southwest of Johannesburg,...

Speaking at a G20 event centered on religion's role in helping solve global problems, an Iraqi archbishop warns that Christianity in his country is "on the very edge of extinction." The Most Rev. Bashar Warda, the Chaldean Catholic Archbishop of Erbil, spoke last week at the G20 Religion Forum in Bali, Indonesia, an event attended by more than 300 religious leaders from across the globe. He gave a speech titled "The Future of Religious Pluralism: A Warning from Iraq," a copy of which was emailed to The Christian Post. During his remarks, the archbishop stressed that "sectarian violence" is a...

Jaws may have terrified you at the cinema, but the iconic great white would have been dwarfed by Carcharocles megalodon, the largest shark in the history of the planet. The giant creatures lived between 23 million and 2.6 million years ago and scientists are divided over how and why the species perished. Now, details of fossils from the huge shark that lived alongside the dinosaurs have been studied for the first time in an attempt to solve this mystery.

About 2.6 million years ago, an oddly bright light arrived in the prehistoric sky and lingered there for weeks or months. It was a supernova some 150 light years away from Earth. Within a few hundred years, long after the strange light in the sky had dwindled, a tsunami of cosmic energy from that same shattering star explosion could have reached our planet and pummeled the atmosphere, touching off climate change and triggering mass extinctions of large ocean animals, including a shark species that was the size of a school bus. The effects of such a supernova—and possibly more than...

If autonomous weapons are the future of warfare, then the United States has no choice but to grapple with their complexities. he congressionally appointed National Security Commission on Artificial Intelligence recently concluded that “we can expect the large-scale proliferation of AI-enabled capabilities.” The recent Libya conflict seems to validate that conclusion about artificial intelligence (AI), with soldiers loyal to Libyan Gen. Khalifa Haftar employing a Turkish-made Kargu-2 drone that “hunted down and remotely engaged” retreating forces, according to a United Nations report. It’s not clear whether the Kargu-2 employed its autonomous capabilities, but the Turkish government acknowledged it can field...

We’ve long known a disaster took place about 66 million years ago, where in a geological instant, 75% of the plants and animals on Earth were wiped out, including all the land-roaming dinosaurs. But here’s a new detail about that event: Even though we can’t pinpoint exactly what year this disaster took place, we now know it happened during the springtime. Most scientists agree the disaster was an asteroid impact, where an asteroid at least 10 kilometers wide struck the Chicxulub region in the present-day Yucatán Peninsula in Mexico. The impact released 2 million times more energy than the most...

nce a rarity, cows with light blue or dark ultramarine hides may again be glimpsed grazing on the Latvian countryside among the regular brown, black or white spotted cattle. The unique and hardy breed, driven to near extinction during the Soviet era, has made a comeback over the last few decades as an unlikely symbol of Latvian national identity.... In 2000 there were only 18 blue cows in Latvia, but today they number around 1,500 -- thoroughbreds as well as hybrids. Originally found only on the Baltic coast in the Kurzeme region...

SMETHPORT, Pa. (AP) - Some Democrats here in rural Pennsylvania are afraid to tell you they’re Democrats. The party’s brand is so toxic in the small towns 100 miles northeast of Pittsburgh that some liberals have removed bumper stickers and yard signs and refuse to acknowledge their party affiliation publicly. These Democrats are used to being outnumbered by the local Republican majority, but as their numbers continue to dwindle, the few that remain are feeling increasingly isolated and unwelcome in their own communities. “The hatred for Democrats is just unbelievable,” said Tim Holohan, an accountant based in rural McKean County...

A majority of Americans now believe democracy in the United State is in danger of disappearing, according to a troubling new poll. Just 26% of those surveyed said they felt US democracy would be secured for future generations, while 51% agreed with the statement, “U.S. democracy is at risk of extinction.” An additional 23% said they were unsure, according to data from Schoen Cooperman Research.

Kazimierz Woycicki, a specialist on Eastern Europe at the University of Warsaw, says that there are six possible scenarios for Russia’s future. From Moscow’s perspective, four are disastrous; and two are more hopeful although apparently in the Polish scholar’s view less likely. The four negative scenarios, he suggests, include “the territorial disintegration of the Russian Federation,” “the gradual but peaceful falling apart of Russia,” “the Balkanization of Russia,” and “the fall of Russia under the influence of China” (k-politika.ru/mrachnye-prognozy-v-polshe-raspisali-shest-scenariev-budushhego-rossii). The two more positive ones at least from the perspective of the Russian leadership at the present time, Woycicki argues, are...
