|Title||Cygnus A: the cluster, the radio lobes and the nucleus|
|Author||Prof Andrew Fabian|
|Description||The spectacular and powerful radio galaxy Cygnus A is at the centre of an X-ray luminous cluster of galaxies. ROSAT and Chandra observations have revealed that a) the cluster is merging with another, b) the gas immediately round the radio galaxy is relatively cool, c) the radiolobes are themselves X-ray sources and d) the nucleus is both powerful and highly absorbed. XMM-Newton has not yet observed Cygnus A due to visibility constraints, but the orbit has precessed so it is now visible. The large field of view of XMM-Newton and greater high energy sensitivity mean that it will make important advances in our understanding of this violent, X-ray bright, object.|

|Mission Description||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.
