Supernovae usually occur when a star runs out of energy and collapses in on itself, but scientists have just spotted a monstrous star explosion that instead blasted all its energy outward. The result has lasted over 70 days, with the remains of SN 2006gy burning five times brighter than any supernova in recorded history. The explosion would have wiped out any life in the general vicinity, so there are no plans to visit. [GT]
