Description Fast stellar winds from massive stars sweep up the surrounding gas to form bubbles. The shocked stellar wind reaches X-ray-emitting temperatures. Only two bubbles have been confirmed to emit diffuse X-rays: NGC 6888 and S308. Both bubbles are blown by Wolf-Rayet stars, contain processed stellar material ejected by their progenitors, and have X-ray luminosity 1-2 orders of magnitude lower than theoretical predictions. Our AO1 XMM-Newton EPIC observations present the first high-resolution image and clean spectrum of the diffuse X-ray emission from the interior of S308. The S-N of the data was compromised by a high background. We request a re-observation of the AO1 pointing and 3 new observations to study the detailed global structure of S308.

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.
