|Title||High-Resolution Spectroscopy of Comets with XMM|
|Author||Dr Bernd Aschenbach|
|Description||GT- After the unexpected discovery of bright X-ray emission from comet C-1996 B2 (Hyakutake), the subsequent X-ray detection of further comets has shown that comets represent a new class of X-ray sources. The capabilities of XMM, in particular its high spectral resolution, will provide powerful diagnostic tools for understanding the X-ray generation mechanism. Pls. note that the exact coordinates are TBD, and as such the target should not yet be scheduled. In the case that a brighter, not yet discovered comet will be observable with XMM, the coordinates, the time of observation, and some instrument settings will have to be adjusted.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
