Fragment G of Comet Shoemaker-Levy 9 collides with Jupiter. This
picture was taken by the South Pole Infrared Explorer (SPIREX) at UTC
18 July 1994 at 7:41. This brilliant explosion remnant is vastly more
powerful than any other impact we have seen at 2.36 microns so
far. The planet is faint because the exposures were short to avoid
saturating the detectors. These observations were performed by
University of Chicago and Center for Astrophysical Research in
Antarctica (CARA) Astrophysicists Mark Hereld, Hien Nguyen (at South
Pole), Bernard J. Rauscher, and Scott A. Severson.
