Shoemaker/Levy 9 Collision with Jupiter CD-ROMs available
From July 16 through July 22, 1994, fragments of Comet P/Shoemaker-Levy 9 collided
with Jupiter, with dramatic effect. This was the first collision of two solar system
bodies ever to be observed. Shoemaker-Levy 9 consists of 20 discernable fragments with
diameters estimated at up to 2 kilometers, which impacted the planet at 60 km/s.
The impacts resulted in plumes many thousands of kilometers high, hot "bubbles" of gas in the
atmosphere, and large dark "scars" on the atmosphere which have lifetimes
at least on the order of weeks. Smaller bits and dust continue to impact the
planet. Shoemaker-Levy 9 is gone, but as the Earth- and space-based images
show, it did not go quietly.
