Meteorite explodes over Russia


A meteorite streaked across the sky and exploded over central Russia on Friday, raining fireballs over a vast area and causing a shock wave that smashed windows, damaged buildings and injured 1,200 people.
People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt the shock wave, according to a Reuters correspondent in the industrial city 1,500 km (950 miles) east of Moscow.
The fireball, travelling at a speed of 30 km (19 miles) per second according to Russian space agency Roscosmos, had blazed across the horizon, leaving a long white trail that could be seen as far as 200 km (125 miles) away.
Car alarms went off, thousands of windows shattered and mobile phone networks were disrupted. The Interior Ministry said the meteorite explosion, a very rare spectacle, also unleashed a sonic boom.
The energy released when it entered the Earth's atmosphere was equivalent to a few kilotonnes, the academy said, the power of a small atomic weapon exploding.
The early-morning blast and ensuing shock wave blew out windows on Chelyabinsk's central Lenin Street, buckled some shop fronts, rattled apartment buildings in the city center and blew out windows.
The Emergencies Ministry described Friday's events as a "meteorite shower in the form of fireballs" and said background radiation levels were normal. It urged residents not to panic.
The first footage was shot by car dashboard video cameras and soon went viral.
Russians also quickly made fun at the event on the Internet. A photo montage showed Putin riding the meteorite and Nationalist politician Vladimir Zhirinovksy said in jest it was really a new weapon being tested by the United States.
