Russian authorities have managed to haul a huge chunk of the meteor up from the bottom of a lake.
The meteor caused widespread damage and injuries when it exploded over Chelyabinsk in Russia back in February of this year with more than 7,200 buildings damaged and 1,500 people wounded. Chunks of the meteor fell across the region including one piece that punched through the ice of Lake Chebarkul, prompting efforts by scientists to retrieve the fragment for study.

Divers spent the better part of a month hauling the 570kg piece of meteor up from the bottom of the lake, a feat that received a substantial amount of media attention. Rather embarrassingly the chunk crushed the scales and broke in to three pieces while it was being weighed, dampening the success of having recovered it intact.

"Some peculiarities characteristic of stone meteorites prove that it’s a fragment of the Chelyabinsk meteorite," said Prof Sergei Zamozdra. "In all probability, it will rank among the top ten largest meteorites ever found."

The meteor is believed to have originated in the early solar system and dates back over 4.56 billion years.

Wow. A half ton fragment. I hope they cut it open and it's filled with an ooze that comes out and covers the researchers and then eats them by dissolving all their tissue but leaves their bones intact and it just keeps growing and eating people and growing and can't be stopped as it slimes it's way across the Russian countryside until finally a plucky young lad figures out it has an aversion to cold and blasts it with fire extinguishers util it freezes at which point it will be dropped by cargo plane in the heart of the Arctic where it shall remain frozen forever. Or will it?

well, i hope it cracks open on its own, revealing a small creature that people try to kill or sell (out of greed) but then it grows, and grows, and watch out! fortunately, gamera arrives to save a small child that the creature threatens, and humans are safer, and perhaps wiser... for a little while.
