In July 1994, 21 fragments from Comet Shoemaker-Levy 9 collided with Jupiter, each capable of causing global catastrophe if they had struck Earth. Discovered in March 1993 by David Levy and Carolyn Shoemaker, astronomers predicted the collision a year in advance after tracking the comet’s fragmented path.

In July 1994, 21 fragments of Comet Shoemaker-Levy 9 collided with Jupiter. Each fragment carried enough force to cause a global catastrophe if it had struck Earth. Astronomers first observed the comet in 1993 and, through careful tracking, accurately predicted the impact more than a year in advance—forever changing our understanding of cosmic threats.
