G305, one of the nearest giant HII regions, contains a WR binary, eight distinctclusters each containing hundreds of stars and eight maser sources and HIIregions each containing 4-8 very young O stars. The bubble contains virgul30 O starssuggesting a population virgul15,000 cluster members. A 125-ks ACIS exposure willdetect all of the high-mass stars and a high fraction of the low-mass YSOs in central clusters and HII regions. A 60-ks EPIC exposure will do the same in thesparser outer clusters and HII regions. The EPIC observation may detect diffuseemission in the inner cavity or within the optical HII region RCW 74.

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.
