Outburst from Comet 9P/Tempel 1 as seen from Hubble

The Hubble Space Telescope was 120 million kilometres away from the comet when this image was taken by the high-resolution Advanced Camera for Surveys (ACS). The telescope's views complement close-up images being taken by cameras aboard Deep Impact, which is speeding toward the comet.

This image, snapped at 14:15 (UT/GMT) on 14 June, reveals the 'jet' (the bright fan-shaped area). The jet extends about 2200 kilometres, which is roughly the distance from Copenhagen to Athens. It is pointing in the direction of the Sun.
