Meteor strike in Antarctica

Pravda:

The blast, which occurred in the sky above Antarctica about 480,000 years ago, was similar to the Tunguska meteorite disaster of 1908. 

The report presented at the conference for paleontology and the exploration of the moon in Texas unveiled the results of the analysis of spherical microparticles discovered in Antarctica. 

The fine particles were found in the Transantarctic Mountains, in a region called Miller Butte. 

“We've got similar material spread over a very large area. It's difficult to do that with any other mechanism. These events are tricky to spot after they happen. If you go to Tunguska now, you've really got your work cut out trying to find any trace of that event – and that was 1908. What makes [the] work so exciting is that it may give us a way of spotting these events in the geological record. If these spherules are the signature, we know what to look for in future,” Imperial College London expert Dr Phil Bland told the BBC.
