A year ago on Saturday, inhabitants of the Russian city of Chelyabinsk looked skyward, some frozen in fear that a nuclear war had begun.
Overhead, an asteroid exploded in a ball of fire, sending debris plummeting to Earth in brilliant streaks.
The shockwave blew out windows, hurting about 1,600 people, and the burst of ultraviolet light was so strong that more than two dozen people suffered skin burns.
