The newly repaired Hubble Space Telescope is sending back exquisite pictures of debris from an object that collided with Jupiter, NASA officials said. Scientists interrupted calibration of Hubble's new Wide Field Camera 3, installed by astronauts in May, to photograph the debris field 360 million miles away, said Heidi Hammel, Hubble's lead astronomer at the Space Science Institute in Boulder, Colo.

It was first detected in a photograph taken on the night of March 24, 1993 with the 0.4-meter Schmidt telescope at the Mount Palomar observatory in California, and subsequently observed by many other astronomers. The comet was extremely unusual because it was in fragments, evidently due to a close encounter with the planet...
