Welcome to the XMM-Newton Science Operations Centre

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.

News and Highlights

High-Speed winds Powerful winds spotted from mysterious X-ray binaries, 28-Apr-2016
ESA's XMM-Newton has discovered gas streaming away at a quarter of the speed of light from very bright X-ray binaries in two nearby galaxies.

Spinning Neutron Star Found: Andromeda's first spinning neutron star, 31-Mar-2016
Decades of searching in the Milky Way's nearby 'twin' galaxy Andromeda have finally paid off, with the discovery of an elusive breed of stellar corpse, a neutron star, by ESA's XMM-Newton space telescope.

Winds from Spiral Galaxy A Milky Way twin swept by an ultra-fast X-ray wind, 14-Jan-2016
ESA's XMM-Newton has found a wind of high-speed gas streaming from the centre of a bright spiral galaxy like our own that may be reducing its ability to produce new stars.

Stephan's Quintet Sparkling Stephan's Quintet, 21-Dec-2015
The Stephan's Quintet of galaxies was discovered by astronomer Édouard Stephan in 1877. At the time, however, he reported the discovery of 'new nebulae', as the concept of other galaxies beyond our Milky Way was only formalised in the 1920s.

Black Hole NuSTAR Finds Cosmic Clumpy Doughnut Around Black Hole, 17-Dec-2015
The most massive black holes in the universe are often encircled by thick, doughnut-shaped disks of gas and dust. This deep-space doughnut material ultimately feeds and nourishes the growing black holes tucked inside.

Galaxy Clusters Unravelling the Cosmic Web: Survey gives insights into Universe's structure, 15-Dec-2015
Today marks the release of the first papers to result from the XXL survey, the largest survey of galaxy clusters ever undertaken with ESA's XMM-Newton X-ray observatory.

Galaxy Clusters XXL Hunt for Galaxy Clusters, 15-Dec-2015
ESO telescopes have provided an international team of astronomers with the gift of the third dimension in a plus-sized hunt for the largest gravitationally bound structures in the Universe — galaxy clusters.
