| Description | By means of X-ray shadowing we want to study the state and properties of the general undisturbed local interstellar medium, that has not (recently) been processed by star formation and feedback by stellar winds and supernova explosions. Therefore we are explicitely targeting a nearby molecular cloud without ongoing or recently stopped star-formation. Such clouds may be not as dense as others but can compensate this by absence of X-ray bright young stellar objects that would have to be excised anyhow in our analysis, and that could have changed the physical state and properties of the surrounding interstellar medium. We propose to observe the star-ess Cha-III dark cloud for 80 ks in order to determine the on-/off-cloud emission properties of the LISM at (l,b)=(303,-17) |

| 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. |
