Collage of the XMM-Newton images

Images of Comet 9P/Tempel 1 taken by the Optical Monitor on ESA's XMM-Newton observatory, from two minutes before impact and until seven minutes after impact. The first two images were taken just before impact, and in the following images the brightening due to impact is visible. These images were taken with the Optical Monitor blue filter, with which it is possible to measure the outcoming gas and dust.
