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.
Spectacularly bright object in Andromeda caused by 'normal' black hole, 23-Feb-2012
A spectacularly bright object recently spotted in one of the Milky Way's neighbouring galaxies is the result of a "normal" stellar black hole, astronomers have found.
