Looks like a meteorite hit Chelyabinsk, a city in the Ural region of Russia. Russian Machine Never Breaks, a hockey blog, has collected a ton of videos and photos of the event, including the video below. There are photos of windows blown out a building that looks like it got hit. (Via @darth)
Here's a link from RT.com with more info and maps.
Unclear if this is the meteorite Bad Astronomy talked about on Monday that is supposed to come close to Earth on 2/15.
