Two huge meteors simultaneously slammed in to what is now Sweden roughly 468 million years ago.
The rare double impact event occurred during a period of intense bombardment brought about by a violent collision in the asteroid belt between Mars and Jupiter.
The largest of the two craters, which measures 4.7 miles across, is located to the south of the city of Östersund while the second, which measures half a mile wide, is situated a short distance from it.
“Around 470 million years ago, two large asteroids collided in the asteroid belt between Mars and Jupiter, and many fragments were thrown off in new orbits,” said geologist Erik Sturkell.
“Many of these crashed on Earth, such as these two
