On April 21, the 2012 Lyrid meteor shower peaked in the skies over Earth. While NASA allsky cameras were looking up, astronaut Don Pettit aboard the International Space Station trained his video camera on Earth below. Video footage has revealed breathtaking images of meteors ablating -- or burning up -- over Earth at night. This video is a composite of 310 still frames from that evening.
Evidence that Barringer Crater was formed by a meteorite impact includes high pressure minerals, overturned sedimentary rock layers, rock debris and fragments of the meteorite.
The mesosphere is where two seemingly magical phenomena take place: meteors and the aurora.
