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.

Where is the Universe’s missing matter?, 18-Apr-2018
Astronomers using ESA's XMM-Newton space observatory have probed the gas-filled haloes around galaxies in a quest to find 'missing' matter thought to reside there, but have come up empty-handed - so where is it?

Perseus cluster: Scientists surprised by relentless cosmic cold front, 03-Apr-2018
A gigantic and resilient "cold front" hurtling through the Perseus galaxy cluster has been studied using data from NASA's Chandra X-ray Observatory - for regions close to the center of the cluster - along with data from ESA's XMM-Newton and the now-defunct German Roentgen (ROSAT) satellite for regions farther out.

Crab Nebula in ultraviolet, 19-Mar-2018
The Crab Nebula is a supernova remnant some 6500 light-years from Earth in the constellation of Taurus. The image shown here is in ultraviolet light taken by ESA’s XMM-Newton telescope, which has been surveying the sky since 2000.

XMM-Newton spies first clear X-ray flares from massive stellar lighthouse, 26-Feb-2018
In 2014, ESA's XMM-Newton spotted X-rays emanating from the massive star Rho Ophiuchi A and, last year, found these to ebb and flow periodically in the form of intense flares – both unexpected results.

Stellar winds behaving unexpectedly, 02-Feb-2018
ESA's XMM-Newton has spotted surprising changes in the powerful streams of gas from two massive stars, suggesting that colliding stellar winds don't behave as expected.
