Geochemists uncover evidence of massive Antarctic meteorite explosion 430,000 years ago

Around 430,000 years ago, a giant meteorite exploded in mid-air over Antarctica, scattering vaporised material thousands of miles across the continent. The discovery by a team of geochemists, is unusual because ‘airburst’ events of this type, which don’t form impact craters, are usually only identified through eyewitness accounts, rather than chemical analysis of geological samples.
