Around 4am Thursday morning, a massive fireball lit up the sky between Phoenix and Tuscon. It was accompanied by a boom that shook windows, and woke people for miles in every direction. Almost instantly people began posting videos of the blinding light and the strange trail left in its wake.
Bits of meteor ranging in size from pebbles to grapefruit rained down in the town of Cibecue, Laurence Garvie, curator of the Center for Meteorite Studies at Arizona State University, told the Associated Press. Garvie believes that this wasn't a part of a meteor shower, but a single space rock that intersected with Earth's orbit.
