Hubble Snaps Jupiter

Astronomers are still recalibrating the Hubble Space Telescope after the repairs made during a shuttle mission last May, but they decided getting an early image of the damage done to Jupiter by the impact of an object last week was important enough to interrupt the recalibration process.

Using Hubble's Wide Field Camera, which was ready to go in any case, they got a sharp image of the area of Jupiter's atmosphere which was entered by the object, likely a comet. The site is near Jupiter's south pole, and, according to one astronomer, the scar is about the size of Earth's Pacific Ocean.
