Comet Hyakutake
In March 1996 for the first time X-ray emission from a comet was detected. This surprising discovery was made during the comet Hyakutake's close approach to the earth. The X-ray emission was detected with the HRI in the 0.1 - 2.0 keV energy band and later on also seen in the data of the EUV telescope (WFC, 0.09 - 0.2 keV band) onboard ROSAT. The image shows the measured intensity of both instruments as contour lines (inside HRI, outside WFC) overlayed to an optical image taken with a common camera during the ROSAT observation.
