PV - IC443 is called a middle-aged supernova remnant possibly not much olderthan 1000 years with a diameter of about one degree. At least the northeasternsection lies behind a molecular cloud, which gives rise to significantvariations in photoelectrical absoption across the remnant. The remnant containsat least three sub-shells of significantly different surface brightnessesindicating different evolutionary states. Four observations covering the entireremant are used to verify EPIC.s spectral and spatial capabilities over a largedynamical range for an extended source of highly complex spectral and spatialtopology.

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.
