| Description | RGS spectroscopy of a bright knot in one of the nearest supernova remnants (the Cygnus Loop), together with high quality EPIC images and spectra, provides a unique opportunity to understand the nature of the supernova remnant/inter- stellar medium interaction. By making use of the EPIC images as templates for the dispersed image of the knot environs, the O VII lines will be extracted. The O VII forbidden to resonant line ratio and the O VIII to O VII line ratio allow the determination of the physical length of the emitting region along the line of sight. The EPIC spectra will allow accurate determination of the temperature distribution over this portion of the supernova remnant. |

| 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. |
