Craters of two large asteroids were located in Jämtland, Sweden. It is presumed that asteroids fell at the same time.
If this is the case, then these asteroids are the first confirmed simultaneous asteroid crashes. Bigger one is 4.7 miles wide, while the smaller one is 1.3 miles wide. Two asteroids fell into the sea about 470 million years ago. During that period, Jämtland was under the shallow sea.
According to professor of geophysics at the university Erik Sturkell, two large asteroids crashed in the asteroid belt between Mars and Jupiter. Pieces of those asteroids were scattered in other orbits. These two fallen asteroids were pieces created in that collision.
Geologist Sturkell concluded that matching sequences are present in both craters. Also, the sediment above the impact sequences is of the same age.
When meteors hit the Earth, the water was driven away so the craters were dry for a short period of time.
This latest discovery could be used to provide clues to extinction events, as scientists believe that there is a connection between impact craters and mass extinctions.
An example of this theory is the Chicxulub crater in Mexico. This crater is 65million years old and it could be connected with the end of the dinosaurs.
Even though NASA has released an official statement which claims that nothing will hit earth for several hundred years, doomsday theorists said that a giant asteroid will hit the Earth by the end of this month.
