World's largest asteroid impact zone believed uncovered by ANU researchers in central Australia

Australian scientists have uncovered what is believed to be the largest asteroid impact zone ever found on Earth, in central Australia.
A team lead by Dr 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.
"They appear to be two large structures, with each of them approximately 200 kilometres," Dr Glikson said.
"So together, jointly they would form a 400 kilometre structure which is the biggest we know of anywhere in the world.
"The consequences are that it could have caused a large mass extinction event at the time, but we still don't know the age of this asteroid impact and we are still working on it."
