In Sweden, discovered a unique double impact crater

Researchers from the University of Gothenburg have found traces of the fall two huge meteorites in Sweden. Meteorites fell a long time ago, about 460 million years ago. Scientists say about the discovery of two craters, one of which can be called a giant, the second - a large, its size is 1/10 the size of the first.

According to experts, the meteorites fell at the same time 458 million years ago, forming the two impact craters. The size of the first, the biggest, the crater is 7.5 kilometers. The second crater with a diameter of 700 meters is located 16 kilometers from the first one.

According to scientists, meteorites formed 470 million years ago in a collision of two large asteroids somewhere between Mars and Jupiter. Fragments of asteroids left the orbit, and some of them fell to the ground. And the place of the fall of two of these fragments just found in Sweden.

The place where fallen meteorites that had previously been covered with a sea depth of 500 meters. The water for a few minutes left of this place (part of the evaporated portion was dropped to kilometers) and the bottom of the sea naked. With a lot of water is claimed fragments formed when a meteorite collision with the bed, these fragments are also found by geologists.

It should be noted that in this region, scientists have found several dozen small meteorites that have survived the fall.
