Another near-miss for Russia

2013 Russian MeteorIn broad daylight over Chelyabinsk, Russia, a meteor likely less than ten feet in diameter unexpectedly appears in the sky and explodes in mid-air. The resulting sonic boom and shockwave break hundreds of windows, causing several hundred minor injuries and collapsing part of a building. Unsettlingly, the meteor is confirmed to be completely unrelated to the much-anticipated asteroid 2012 DA14, which is over 16 hours away from its closest approach to Earth.
