A 400 kilometer-wide impact zone from a huge meteorite that broke in two moments before it slammed into the Earth has been found in Central Australia. The crater from the impact millions of years ago has long disappeared. But a team of geophysicists has found the twin scars of the impacts -- the largest impact zone ever found on Earth -- hidden deep in the earth's crust.
