The planet Jupiter's southern hemisphere is dotted with dark smudges where comet segments struck the planet. The impact sites are roughly in line.

Jupiter dotted with Shoemaker Levy 9 impact sites

Image of Jupiter taken by the Hubble Space Telescope's Planetary Camera. Eight impact sites are visible. From left to right are the E/F complex (barely visible on the edge of the planet), the star-shaped H site, the impact sites for tiny N, Q1, small Q2, and R, and on the far right limb the D/G complex. The D/G complex also shows extended haze at the edge of the planet. The features are rapidly evolving on timescales of days. The smallest features in this image are less than 200 kilometers across.
