Plume from the explosion of the first fragment of Comet Shoemaker-Levy
9 observed by the South Pole Infrared Explorer (SPIREX). Images are
shown before the impact, and about 20 minutes after the impact when
the impact site has rotated into view. Both images show Io, the
innermost large moon of Jupiter (bright spot to the right) and dimmer
polar regions. The impact site is the bright spot to the lower
left. These observations were performed by University of Chicago and
Center for Astrophysical Research in Antarctica (CARA) Astrophysicists
Mark Hereld, Hien Nguyen, Bernard J. Rauscher, and Scott A.  Severson.
