World’s Largest Asteroid Impact Zone is 400 km Wide

Central Australia has recently been discovered as the world’s largest asteroid impact zone. The last attack happened to be millions of years ago and there was no proof or signs of any impact until now.

Now, a team of geophysicists have found some trails in the form of twin scars during a geothermal research. Dr Andrew Glikson, lead researcher from the ANU school of Anthropology and Archaeology said that they found the impacts during a research drill in an area on the borders of Queensland, South Australia and the Northern Territory.

Both the asteroids must have been over 10 kilometers across, says Dr Glikson. However, the exact time of the collision still remains a mystery. These marks extended through the Earth’s crust which is around 30 kilometers in that area.

The research is published in journal tectophysics.
