Massive stars disperse the ISM by a combination of their powerful stellar winds,supernova (SN) explosions and their UV fluxes. At large scales (>1 kpc) the UVradiation plays a critical role in the evolution of galaxies, but at smallerscales (<100 pc) stellar feedback influence their stellar nurseries.Observational studies have been presented in the recent years arguing that theradiation pressure is significantly more important that the pressure resultedfrom the hot bubble interiors, but we note that such studies draw conclusions byinterpreting low spatial resolution ROSAT X-ray observations. We started arevisitation of the X-ray properties of superbubbles in the LMC taking advantageof a superior effective area and rejection of contaminant point sources using XMM.

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.
