| Description | MBM16 is a dense molecular cloud at high Galactic latitude (l=170,b=-38,d=60-95 pc) whose absorption of the X-ray background has been used to measure the strength of the Galactic halo. Liu et al. has recently claimed that the background X-ray emission towards MBM16 is not consistent with a significant Galactic halo and suggested that previous halo measurements using the nearby MBM12 and MBM20 clouds are wrong. However, ROSAT measurements of these clouds do suggest significant halo emission. Using a new observation strategy, we propose an observation of MBM16 that will measure the halo emission, settle this apparent disagreement, and avoid the complication of solar wind charge-exchange. |

| 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. |
