Divers have retrieved an enormous fragment of the meteor that exploded over Russia in February. It has been brought up from the bottom of Lake Chebarkul in the Urals.
The piece of space rock is believed to be the largest to hit earth when a meteor broke up above the towns of Chelyabinsk, Yekatarinburg and Tyumen.
Scientists from the University of Chelyabinsk led the recovery. Andrei Kochekov, Director of Innovation and Expertise at the university, told reporters: “If its weight is more than 500 kilograms then the object is unique in itself. One of the biggest meteors of its class, the stone type.”
The force of the shock wave of the meteorite was estimated to be as strong as 20 Hiroshima atomic bombs. More than 1,600 people were injured by the effects of its landing.
Thousands more watched in awe as the meteor exploded before their eyes, falling to earth in a shower of light.
