Although not the usual spacecraft-related fare, this video of a meteor entering the atmosphere over Russia is truly extraordinary.
The event, which is reported to have caused significant injury and property damage, occurred earlier this morning and has been widely reported by the media. It is not clear what, if any, relationship this meteor has to 2012 DA14, which will pass within about 17,000 miles of Earth today.
Numerous pop-up ads will appear when the video is played. You may want to clear them out for a clearer view.
