One hundred forty-two million years ago, an asteroid or comet slammed into what is now the
Missionary Plains in Australia’s Northern Territory, forming a crater 24
kilometers in diameter. Today, like a bull’s eye, the circular ring of
hills that defines Gosses Bluff stands as a stark reminder of the event.
