Russian authorities claim to have found the impact sites of some of the fragments of the Chelyabinsk meteor, according to the RIA Novosti news agency. Two have been found near Chebarkul Lake—one of them pictured here. The other one is near Zlatoust, a town 80 kilometres north-west of Chelyabinsk.
Scientists and police have recovered small black fragments encrusted in the ice. They believe they are part of the meteor's debris.
The Russian Academy of Sciences has estimated that the meteorite weighed about 10 tons and entered the Earth's atmosphere at a speed of at least 33,000 mph, shattering about 18-32 miles above ground.
