For the first time, scientists have proven that a pair of craters in central Sweden were created at the same time; this rare double impact crater is thought to be the result of two meteorites simultaneously crashing into Earth over 450 million years ago.
New research has uncovered a pair of impact craters in central Sweden near the current-day city of Östersund.
Scientists have found that they were likely formed over 450 million years ago when two meteors simultaneously crashed into Earth.
The larger one, which is 4.7 miles in diameter, is about 10 miles away from its much smaller companion which is just under half a mile wide.
