Description We propose to observe the Cygnus Loop to investigate the progenitor star and study its roots. Based on the ASCA observation, we found that there was a metal rich plasma left in the core of the Loop. It must be a fossil of the supernova explosion. The relative abundance ratio suggested that the Cygnus Loop originated from the 25 Msun star expecting the production of a compact star. The scientific goal of the observation is to study the fossil: what the structure of the fossil is, how it is mixing with the ISM, what makes an asymmetry.

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.
