Fast winds from massive stars create large cavities in the surroundinginterstellar medium filled with hot gas, known as Wind-Blown Bubbles (WBB). Wepropose to obtain EPIC imaging spectroscopy of the WBB NGC 2359. Thanks to theEPIC excellent sensitivity, we will: (i) obtain a high quality CCD spectrumwhich can be used to constrain the temperature of the hot plasma and theefficiency of thermal conduction across the bubble wall, (ii) determine thespatial distribution and properties of X-ray emitting plasma, (iii) test andrefine shock physics models of WBB by a direct confrontation of their resultswith observations; (iv) study the X-ray properties of the presumably single WRstar WR 7.

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.
