Meteor chunk recovered from Russian lake

Russian scientists have recovered a giant chunk of the Chelyabinsk meteor from the bottom of the lake it crashed into.

The meteor, which blazed across the southern Urals in February, was the largest recorded meteor strike in over a century. More than 1,600 people were injured by the shockwave from the explosion, estimated to be as strong as 20 Hiroshima atomic bombs, as it landed near the city of Chelyabinsk.
