Comet Shoemaker-Levy 9 was on a collision course. The comet had once orbited Jupiter, circling the gas giant every two years. But during a close encounter with the planet, it was ripped apart by tidal forces. A trail of fragments, some greater than 3,000 feet across, was all that remained of the icy mass. In July 1994, the fragments raced towards Jupiter’s south pole, exploding into fireballs as they entered the cloud-filled atmosphere. Each impact set off fiery plumes that could be seen by observing spacecraft. The event, which took place over six days, was the first collision of two bodies in the solar system ever witnessed by humans. Watch the visualization to see a re-creation of this historic clash.

This time-lapse sequence shows the temporary scars (dark spots) that formed in Jupiter's atmosphere following the impact of two comet fragments.
