World's largest asteroid impact zone found in Australia

Canberra, March 23 , 2015: Scientists have uncovered in central Australia what is believed to be the largest asteroid impact zone ever found on Earth, a media report said on Monday.

A team lead by Andrew Glikson from the Australian National University (ANU) said two ancient craters found in central Australia were believed to have been caused by one meteorite that broke in two, ABC reported.

"They appear to be two large structures, with each of them approximately 200 km," Glikson said.

"So together, jointly they would form a 400 kilometre structure which is the biggest we know of anywhere in the world," Glikson added.

The material at both impact sites appears to be identical which has led researchers to believe they are from the same meteorite.

According to the researchers, there are many unanswered questions about the underground site and whether the twin asteroid impact could have affected life on earth at the time.

"When we know more about the age of the impact, then we will know whether it correlates with one of the large mass extinctions at the end of specific eras," Glikson said.
