JUPITER-SL9 ENCOUNTER

 

On July, 8th 1992, during a close flyby over Jupiter, the comet Shoemaker-Levy 9 (discovered in March 1993) cracked into many fragments. These fragments came back and crashed into Jupiter one after the other during the third week of July 1994, at a speed of 60 km/s. Due to the rotation of Jupiter, the series of crashes caused a belt of plumes (some of them larger than Earth) at the latitude of 44 south. The name of the impacts were derived from the names of the 21 fragments (from A to V), several hundred meters wide in average, detected by HST observations before the collision.

All images are composites taken with a 130 mm (5") Clavé refractor at F/D 30 (Barlow lens and IR-blocking filter) and a Hi-SIS 22 CCD camera. Site: Pic-du-Midi Observatory (France). Authors: Christian Buil, Alain Klotz, Thierry Legault. Processing with MiPS software by Thierry Legault.
