On this day 13 years ago comet Shoemaker-Levy-9 began a six-day assault on Jupiter's southern hemisphere. In this blue-light image from the Hubble Space Telescope Wide Field Planetary Camera-2, the dark spot 23 hours later from that first hit is located in the lower middle, flanked by two other fragment impact areas. These cloud disturbances can each be roughly compared to an Earth diameter in size. Jupiter's Great Red Spot is seen at upper right. Credit: John Clark/NASA HST.
