One hour after impact

This image is one of a sequence from the NASA/ESA Hubble Space Telescope which shows the comet before and after the impact.

Hubble continued to monitor the comet after the impact, snapping another image 62 minutes after the encounter. In this photo, the gas and dust ejected during the impact are expanding outward in the shape of a fan. The debris extends about 1800 kilometres from the nucleus. The images was taken by the Advanced Camera for Surveys' High Resolution Camera.
