Meteor Explodes Over Russia

At about 9:30 this morning in Chelyabinsk, Russia, a big meteor burned up in the sky, close enough to be caught by many of the ubiquitous Russian dash-cams. The fireball caused a sonic boom, and there are reports of many injuries from shattered windows and falls, but no deaths are reported so far. Phil Plait is constantly updating a post at Bad Astronomy regarding the meteor, with many other videos.
