Due to stringent requirements regarding evidence and peer-reviewed publication, newly discovered craters or those with difficulty collecting evidence generally are known for some time before becoming listed. "The feature may mark the site of a 480 km (300 mi) wide impact crater buried beneath the ice and more than 2.5 times larger than the 180 km (110 mi) Chicxulub crater." A look back at the esteemed personalities who've left us this year, who'd touched us with their innovation, creativity and humanity. Far below the thick ice sheet that covers Antarctica, there are lakes of fresh water without a direct connection to the ocean. sciencefocus.com - Scientists recovered extra-terrestrial particles on the summit of Walnumfjellet within the Sør Rondane Mountains in east Antarctica.

Antarctica is in an unstable and uncertain situation. The asteroid impact that killed the dinosaurs 65 million years ago was big, but geologists have found a new asteroid crater that’s even bigger: in Antarctica. To miss it would be a crime. But Von Frese hopes to make a research trip to Antarctica to look for rocks at the base of the ice sheet along the continent's coast that could attest to an impact. The data revealed a 200-mile-wide area where the Earth's denser mantle layer bounced up into the planet's crust. The crater was sighted by Dr. Christian Müller, a geophysicist in Antarctica with the surveying company Fielax. © 2006 The Associated Press. When the scientists overlaid their gravity image with airborne radar images of the ground beneath the ice, they discovered imprints of lumps and ridges from the meteor that indicated impact. He's an acrobat, dancer, and Oscar-nominated actor who appeared in such memorable films as "Seven Brides for Seven Brothers" and "West Side Story" – and the less-memorable "War of the Gargantuas." Correspondent Lee Cowan reports. Bill Whitaker reports on how decades of research show that racism is adversely affecting Black Americans' health in several different ways. A huge potential crater has been discovered in Antarctica via gravity measurements from space. Tsunami 10 years later: Are we better prepared? The rift cuts directly through the crater, so the impact of the meteor may have helped the rift to form, he said. 13 DECEMBER 2016. Viola Davis opens up to Jon Wertheim about her role as Ma Rainey, her relationship with August Wilson's material, a bold scene on "How to Get Away with Murder" and her life growing up. Demings is a former chief of the Orlando Police Department. Scientists have visited a vast, 2-kilometre-wide (1.2-mile) ice crater in East Antarctica for the first time, and after years of speculation, say they finally know how it got there. Mike DeWine and Congresswoman Val Demings sat down with John Dickerson. The find has led geologists to speculate that the huge meteorite that may have caused it … A massive crater in Antarctica may have been caused by a meteor that wiped out more than 90 percent of the species on Earth 250 million years ago, an American geologist said Wednesday. It is frequently climbed to get good viewing points across the continent. 60 Minutes profiles the group, which has become a central focus in the ongoing investigation of the January 6 attack on the Capitol. https://en.wikipedia.org/wiki/List_of_impact_craters_in_Antarctica The hole, which is in the Roi Baudouin ice shelf in East Antarctica, is a collapsed lake — a cavity formed when a lake of meltwater drained — with a “moulin,” […] ANTARCTICA: A massive crater in Antarctica may have been caused by a meteor that wiped out more than 90 per cent of the species… Huge crater in Antarctica: why do you worry so much? Earlier this month, scientists revealed a massive rift in Antarctica’s Larsen C ice shelf. Paul Seaburn is the editor at Mysterious Universe and its most prolific writer. Von Frese said the satellite data suggests the crater could date back about 250 million years to the time of the Permian-Triassic extinction, when almost all animal life on Earth died out, paving the way for dinosaurs to rise to prominence. Scientists think the crater was formed by one of the asteroids that hit the Earth millions of years ago and caused the extinction of the dinosaurs. Correspondent Tracy Smith talks with industry experts who predict that, for movie studios and brick-and-mortar theater owners, happy days may soon be here again. But for many years, Russ Tamblyn stepped out of the limelight, to pursue a different kind of art. Now, a team of climate researchers has found that a mysterious crater spotted on the King Baudouin ice shelf is proof that the East Antarctic ice sheet may indeed be more vulnerable than expected and may, in some ways, contribute to sea level rise. The crater was found in what's known as the Wilkes Land region of the East Antarctic Ice Sheet. A “crater” in Antarctica once thought to be the work of a meteorite impact is actually the result of ice melt, new research finds. Shows, movies and documentaries you'll want to stream soon. According to Von Frese, the mass concentration GRACE detected in Antarctica could be the crater from an asteroid that triggered the Permo-Triassic extinction. There are not yet any confirmed impact sites in Antarctica according to the Earth Impact Database. He said he wanted to visit Antarctica to hunt for rocks at the base of the ice along the coast that could be dated. Turner Classic Movies host Ben Mankiewicz sits down with Oscar-winning actor Jon Voight, to talk about his celebrated performances in such films as "Midnight Cowboy," "Deliverance" and "Coming Home"; about the controversy that his conservative political views currently attracts; and whether he'd like to be directed by his daughter, actress and filmmaker Angelina Jolie. Correspondent Mo Rocca snaps fingers with the 86-year-old Tamblyn, who talks about his film and TV career – and about teaching Elvis Presley how to move. A massive area of fractured ice more than a mile wide (2 kilometers across) could by an meteorite impact crater in East Antarctica's King Baudoin ice shelf. The discovery indicated a so-called low-altitude meteoritic touchdown event – where a jet of melted and vaporised material from an asteroid at least 100 metres in size reached the surface at high velocity. However, entries on the unconfirmed list could still have an impact origin disproven. On this "Face the Nation" broadcast, Ohio Gov. The crater's size and location, von Frese said, also indicated that it could have begun the breakup of the Gondwana supercontinent by creating a tectonic rift that pushed Australia northward. The following craters are officially considered "unconfirmed" because they are not listed in the Earth Impact Database. "This Wilkes Land impact is much bigger than the impact that killed the dinosaurs, and probably would have caused catastrophic damage at the time," he said. Space. SUMMARY: The asteroid impact that killed the dinosaurs 65 million years ago was big, but geologists have found a new asteroid crater that's even bigger: in Antarctica. Tags Antarctica climate change crater Global warming natural world Science. 2021-04-06. admin. The FBI calls the Oath Keepers an anti-government militia with current and former law enforcement and military members among its members. A massive crater in Antarctica may have been caused by a meteor that wiped out more than 90 percent of the species on Earth 250 million years ago, an American geologist said Wednesday.

Prince Philip, who died at age 99, was the patriarch of the British royal family. Large Antarctic Crater Created by Underground Flood By Becky Oskin 02 July 2013 A surface crater in the ice left behind after a buried glacial lake flooded and lost its water in Antarctica. Researchers recovered extra-terrestrial particles on the summit of Walnumfjellet within the Sør Rondane Mountains in east Antarctica. This List of impact craters in Antarctica includes only unconfirmed and theoretical impact sites in Antarctica and the surrounding waters of the Southern Ocean. CBS News director of elections and surveys Anthony Salvanto joins CBSN's Lana Zak with a look at the latest numbers. Scientists recovered extra-terrestrial particles on the summit of Walnumfjellet within the Sør Rondane Mountains in east Antarctica. Observation Hill is a steep 754-foot hill adjacent to McMurdo Station in Antarctica and commonly called "Ob Hill." Impact. This is what would happen in reaction to such a big impact, in the planetary equivalent of a bump on the head, von Frese said. Now that the coronavirus vaccine is available to all adult Americans, the Biden administration is working to make sure that everyone who wants a shot has access to it. New polling from CBS News is shedding light on how Americans feel about the job President Biden has done in his first 100 days in office.
