Update on the Jupiter Impact

Last July 19, 2009, something big crashed into the side of Jupiter. By studying pictures taken by the Hubble Space Telescope of the impact site and comparing them to pictures taken during the July 1994 Jupiter impact from Comet P/Shoemaker-Levy 9, scientists are now calling the culprit a rogue asteroid, of about 1600 feet wide. This asteroid's impact was comparable to the force of a few thousand nuclear exploding, according to NASA.
