First XMM-Newton images of impact
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. More images from the Optical Monitor are expected in the next hours.
Measurements with other XMM-Newton instruments should provide information about the chemical composition of the outcoming material.

XMM-Newton detects water on Tempel 1
These images, taken by the Optical Monitor on board ESA's XMM-Newton observatory on 3 and 4 July 2005, show a comparison between the states of the comet before and just after impact.
The images were taken in the blue (top) and ultraviolet channels (bottom) of the instrument. The ultraviolet images show the emissions of hydroxyl ions, the direct decay product of water.
About 1.5 hours after the impact, the brightness of hydroxyl groups is increased by a factor of about five. Later, about 4.5 hours after the impact the ultraviolet emission is decreased again which indicates that the peak has passed.
The presence of water in Tempel 1 is consistent with preliminary measurements of the composition of the comet made last week by the ALICE instrument on ESA's Rosetta spacecraft.
