Russian scientists say they've found the largest fragment of that meteorite that exploded over the Ural Mountains two weeks ago.

The fragment weighs about four pounds. A ski expedition team found it in a frozen lake nearby.

The meteorite blew up over the Siberian city of Chelyabinsk on February 15, injuring nearly 1,500 people and causing widespread property damage.

Astronomers say they've recovered more than 100 fragments from the space rock, but none as large as this latest discovery.
