| Abstract | GT- G299.2-2.9 is a shell-type SNR of ~10 diameter discovered in the ROSATall-sky survey. It shows bright optical filaments and radio emission at 2.4 GHz.Both from the X-ray data and the radio data the distance cannot be determinedunambigously, but measurements of the column density and x-ray temperature andits distribution will help and clarify the age, for which we have just an upperlimit of 9.000 yrs. |

| 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. |
