Description We propose to observe a probable hot plasma-cold cloud X-ray emitting interface region surrounding the Coalsack Nebula. Such an interface will provide a nearly unique insight into the physical parameters of transition regions, which are a feature of models of the interstellar medium but are not observed (except in active SNR shock fronts). The motivation for the observation is three-fold, to verify the existence of the X-ray bright transition region as observed with in ROSAT data, determine the origin of the X-ray emitting plasma, and determine the physical state of the plasma. Specifically, to answer the question whether the interface region between the cloud and the surrounding hot gas is experiencing evaporation, condensation, or turbulent mixing.

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.
