| Abstract | GT- After the unexpected discovery of bright X-ray emission from comet C/1996B2 (Hyakutake), the subsequent X-ray detection of further comets has shown thatcomets represent a new class of X-ray sources. The capabilities of XMM, inparticular its high spectral resolution, will provide powerful diagnostic toolsfor understanding the X-ray generation mechanism.Pls. note that the exact coordinates are TBD, and as such the target should notyet be scheduled. In the case that a brighter, not yet discovered comet will beobservable with XMM, the coordinates, the time of observation, andsome instrument settings will have to be adjusted. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
