A huge chunk of the meteor that slammed into the Urals last February has been dredged up from the bottom of Chebarkul Lake.
The meteorite could be the largest piece of the so-called Chelyabinsk meteor. When scientists tried to weigh it, the scale showed 570 kilograms before it broke.
The meteor was the largest to hit Earth in a century, causing a blast equivalent to 20 Hiroshima atomic bombs. The shock wave created by the impact injured an estimated 1,600 people.
Sergei Zamozdra, an associate professor at Chelyabinsk State University, told Russian television the excavated fragment was definitely a chunk of the meteor.
