Hundreds Reported Injured in Blast from Meteor Strike over Russia [Video]

A meteor fireball lit up the morning sky over Chelyabinsk in central Russia, producing a shock wave that shattered windows and injured an estimated 500 1,000 people.** Although much of the parent object likely burned up in the atmosphere, Russian authorities say that several meteorite fragments have already been recovered, according to the Interfax news agency.A preliminary analysis posted to the Web site of the Russian Academy of Sciences estimates that the object that struck Earth's atmosphere was a few meters in diameter, "the weight of the order of ten tons [and] the energy of a few kilotons," according to a Google translation.* That would make the Chelyabinsk event a fairly common occurrence, although such strikes usually occur over less-populated regions, not cities of more than a million people.
