Impact Antarctica

Comet Shoemaker-Levy 9 (SL9, formally designated D/1993 F2) was discovered by astronomers Carolyn and Eugene M. Shoemaker and David Levy. Shoemaker-Levy 9 was located on the night of March 24, 1993, in a photograph taken with the 0.4 metre Schmidt telescope at the Palomar Observatory in California. It was the first comet observed to be orbiting a planet.

In July 1992 the orbit of Shoemaker-Levy 9 passed within Jupiter's Roche limit, and Jupiter's tidal forces acted to pull the comet apart. SL9 was later observed as a series of fragments ranging up to 2 kilometres in diameter. The majority of these fragments collided with Jupiter's southern hemisphere between July 16 and July 22, 1994, at a speed of approximately 60 kilometres per second. The prominent scars from the impacts were more easily visible than the Great Red Spot and persisted for many months. three fragments however escaped Jupiter's gravity. They are designated SL9-A, SL9-B and SL9-C.

on the night of August 16th 1994 SL9-A (approximatly 15Km wide) collides with the moon during a full moon roughly on the site of the landing site of Apollo 15. The impact is visible from the west side of Europe and the East coast of the Americas. Once the dust cleared a new crater is visible, scientists measure it at nearly 120Km across. the crater glows for several days as the lava at its base cools. Over the next three days large numbers of metorites impact earth
