A significant excess of very high energy (VHE) gamma-ray emission is observed byH.E.S.S. inside the shell of SNR G284.3--1.8. This source is found to bepoint-like or only slightly extended and at a distance of 0.33d from PSRJ1016-5857. A 1.8 ks Einstein observation reveal a significant excess compatiblewith the VHE source. This association suggests that this could be the actual PWNof MSH 10-53. The estimated flux suggests that this object should be easilydetectable by XMM-Newton.

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.
