100m-Wide Meteor Hit Antarctica 430,000 Years Ago

Saturday, 3 April, 2021 - 04:45 In a photo taken 10/22/17, near Malaga, Spain, a meteor is seen streaking past the constellation Canis Minor during the annual Orionid meteor showers. (Reuters) London - Asharq Al-Awsat Research led by a Kent-based space scientist has uncovered new evidence of meteor particles reaching the Antarctic ice sheet 430,000 years ago. The team said the findings highlight the importance of reassessing the threat of medium-sized asteroids, with the potential for destructive consequences, reported The Metro. Researchers recovered extra-terrestrial particles on the summit of Walnumfjellet within the Sor Rondane Mountains in east Antarctica. The discovery indicated a so-called low-altitude meteoritic touchdown event – where a jet of melted and vaporized material from an asteroid at least 100 meters in size reached the surface at high velocity.

Scientists discover Asteroid impact in Antarctica when Neanderthals were roaming Europe 430,000 years ago

Scientists discover Asteroid impact in Antarctica when Neanderthals were roaming Europe 430,000 years ago It was 430,000 years ago, during the middle of the Pleistocene epoch when the earliest Neanderthals were roaming across Europe that the asteroid had hit the Antarctic Scientists Drill 3,500 Feet Into Antarctic Ice To Find A Mysterious Subglacial Lake A research team studying tiny particles found in Antarctica have uncovered evidence of  an asteroid impact in Antarctica 430,000 years ago, using chemical clues locked in the particles to piece together what happened then. The findings reiterate the need for the identification of these events in deep sea sediment cores and, if plume expansion reaches landmasses, the sedimentary record, said the team of scientists. 

Discovered: New evidence of Asteroid impact in Antarctica

Discovered: New evidence of Asteroid impact in Antarctica The findings indicate an impact much more hazardous that the Tunguska and Chelyabinsk events over Russia in 1908 and 2013 Thursday April 1, 2021 10:25 PM, IANS London: A research team of international space scientists has found new evidence of an asteroid impact in Antarctica 430,000 years ago. Extra-terrestrial particles recovered on the summit of Walnumfjellet (WN) within the Sor Rondane Mountains, Queen Maud Land, East Antarctica, indicate an unusual touchdown event where a jet of melted and vaporised meteoritic material resulting from the atmospheric entry of an asteroid at least 100 metres in size reached the surface at high velocity, said the study.
