Meteorites Revealing Secrets of Russian Fireball

Scientists studying small pieces of the meteor that exploded over the Russian city of Chelyabinsk on Feb. 15 are working to glean new insights into the rare impact by a space rock.

Based on the meteorite analysis, researchers have determined that last month's meteor explosion in Russia — which scientists call a superbolide — produced a shock wave that reached the ground. That shock shattered windows and injured some 1,500 people due to flying glass.
The blast also created a shower of stony meteorites that fell to Earth in an impact region more than 60 miles (100 kilometers) long.
