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.

XMM-Newton maps black hole surroundings XMM-Newton maps black hole surroundings, 21-Jan-2020
Material falling into a black hole casts X-rays out into space - and now, for the first time, ESA's XMM-Newton X-ray observatory has used the reverberating echoes of this radiation to map the dynamic behaviour and surroundings of a black hole itself.

XMM-NEWTON DISCOVERS SCORCHING GAS IN MILKY WAY'S HALO XMM-Newton discovers scorching gas in milky way's halo, 16-Jan-2020
ESA's XMM-Newton has discovered that gas lurking within the Milky Way's halo reaches far hotter temperatures than previously thought and has a different chemical make-up than predicted, challenging our understanding of our galactic home.

FIRST SIGHTING OF HOY GAS SLOSHING IN GALAXY CLUSTER First sighting of hot gas sloshing in galaxy cluster, 10-Jan-2020
ESA's XMM-Newton X-ray observatory has spied hot gas sloshing around within a galaxy cluster - a never-before-seen behaviour that may be driven by turbulent merger events.

XMM-Newton_s_20th_anniversary_in_space_pillars XMM-NEWTON's 20th ANNIVERSARY IN SPACE, 10-Dec-2019
On 10 December, ESA's XMM-Newton X-ray space observatory is celebrating its 20th launch anniversary. In those two decades, the observatory has supplied a constant stream of outstanding science. One area that the mission has excelled in is the science of black holes, having had a profound effect on our understanding of these cosmic enigmas.

For the first time, astronomers have detected synchronised pulses of optical and X-ray radiation from a mysterious pulsar some 4500 light years away. The observations indicate that a new physical mechanism might be needed to explain the behaviour of fast-spinning sources like this one, known as transitional millisecond pulsars.

Unexpected_periodic_flares_may_shed_light_on_black_hole_accretion Unexpected periodic flares may shed light on black hole accretion, 12-Sep-2019
ESA’s X-ray space telescope XMM-Newton has detected never-before-seen periodic flares of X-ray radiation coming from a distant galaxy that could help explain some enigmatic behaviours of active black holes.

XMM-Newton Anniversary Products XMM-Newton Anniversary Products, 28-Aug-2019
Explore the scientific impact of ESA's XMM-Newton observatory for its 20th anniversary in space, as told by Ph.D. scientists whose work the mission enabled. XMM-Newton's telescopes and its ability to make long uninterrupted exposures provide highly sensitive observations of many targets, including active galaxies powered by supermassive black holes, star formation in galaxies, and X-ray flares from stars in our own Milky Way galaxy.
