- This image shows the aftermath of the impacts of several of the
- fragments of Shoemaker-Levy 9 with Jupiter. The image was taken in
- infrared light with a wavelength of 2.3 microns, which is strongly
- absorbed by methane in Jupiter's atmosphere.
-
- The impact sites are the four bright spots at high southern latitudes,
- not to be confused with the Great Red Spot which is visible closer to
- the equator. The site of impact A is just rotating into view on the
- lower left: it is over 30 hours old but is still conspicuous. To its
- right is a very large, bright and complex double spot which we do not fully
- understand yet: it is probably some combination of the fragment E
- impact site, about 12 hours old, and the nearby site of the fragment F
- impact, only two hours old. On the right side of Jupiter, about to
- rotate out of view, is the site of the fragment D impact, about 15
- hours old.
-
- The impact sites, and the other features visible in this image, are so
- conspicuous because they include very high altitude clouds, perhaps
- composed of material blasted up from the deep atmosphere by the
- impacts: these reflect light before it can be absorbed by the methane
- at lower altitudes.

- Technical details: Image taken at 2:30 UT on July 18, 1994, with the
- Ohio State Infrared Imaging Spectrometer (OSIRIS) at the 4-meter
- telescope of the Cerro Tololo Inter-American Observatory in Chile, by
- John Spencer (Lowell Observatory), and Darren DePoy and Jay Frogel
- (Ohio State University).
