According to BBC, the meteorite plunged into Lake Chebarkul on February 15, leaving a giant hole in the ice. The piece of the meteorite that was retrieved weighed a half-tonne, making it the largest fragment of the meteorite yet found.
According to NBC, the retrieval effort was caught on video, and it shows the meteorite's crust, a shiny, glassy layer of black material, which forms when the rock's outer portions melt. The piece of rock also seems to have a regmaglypts shallow surface.
According to Los Angeles Times, the fragment may not provide novel scientific information, but scientists did say that it still provides a boon.
Researchers believe that this may be the largest Chelyabinsk meteorite ever found. Other bits that were found in the past were the size of walnuts.
