MOSCOW -- Russian scientists have recovered a giant chunk of the Chelyabinsk meteorite from the bottom of the lake it crashed into.
The meteor that blazed across southern Urals in February was the largest recorded strike in more than a century. More than 1,600 people were injured by the shock wave from the explosion as it hit near the city of Chelyabinsk, estimated to be as strong as 20 Hiroshima atomic bombs.
Scientists on Wednesday recovered what could be the largest part of the meteorite from Chebarkul Lake outside the city. They weighed it using a giant steelyard balance, which displayed 570 kilograms (1,256 pounds) before breaking.
Sergei Zamozdra, an associate professor at Chelyabinsk State University, told Russian television the excavated fragment was definitely a chunk of the meteorite.
