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 finds two stray supernova remnants
When the European Space Agency’s XMM-Newton pointed its telescope at two unidentified sources of light in the outskirts of the Large Magellanic Cloud, scientists were able to confirm what seemed an unlikely discovery. They found two supernova remnants in the far reaches of our neighbouring galaxy. The two objects that XMM-Newton looked at are shown as the two circles in the lower left of this visible-light image of the Large Magellanic Cloud. Click on the two circles to make the newly-discovered supernova remnants appear: J0624-6948 (orange, higher in the image) and J0614-7251 (blue, lower in the image). The yellow crosses represent supernova remnants that had been found before.

Version 22.0 of the Science Analysis System (SAS) released
The XMM-Newton SAS team is pleased to announce the release of a new version of the SAS : SAS v22.0.

Binaries for diverse flavours of Linux and Mac OS X are available at
     https://www.cosmos.esa.int/web/xmm-newton/sas-download

The main improvements of this release can be found in the Release Notes:
     https://www.cosmos.esa.int/web/xmm-newton/sas-release-notes-2200

This version of SAS is released in three 64-bit binary versions for Linux (Ubuntu 22.04LTS, Ubuntu 24.04LTS and Red HAT 8.10), and two for macOS (13.6.9, Ventura and 14.6.1, Sonoma). A version for Red HAT 9 is intended to be released shortly.

SAS analysis threads have been revised to ensure compatibility with the recently released SAS v22.0. They are available at

The SOC together with its partners at NASA from the XMM-Newton Guest Observer Facility will be hosting its first virtual Data Analysis Workshop April 1-3, 2025!
This workshop, geared towards new and experienced users of XMM-Newton data, will
(1) highlight the diverse scientific studies that can be enabled by XMM-Newton,
(2) introduce beginners to the Science Analysis Software (SAS) and Extended Source Analysis System (ESAS) as well as the XMM-Newton Science Archive (XSA), and
(3) introduce beginners and experienced users alike to SciServer and Datalabs.
The workshop will be split between presentations and hands-on sessions, distributed over more than 12h duration, to allow participants in Europe as well as the US to attend at convenient times. The goal of the workshop is to improve the accessibility and usability of XMM-Newton data and its data reduction and analysis software, and to introduce the tools created for use with SciServer and Datalabs, which focus on making data reduction more accessible regardless of computing resources and expertise available at a given institution. Registration is open HERE and free of charge. To prepare for the workshop, please register for an ESA Datalabs account and familiarise yourself with the interface: REGISTER HERE. Please use the invitation code “XMM2025” when registering with Datalabs, so your account can be assigned to the workshop.

X-ray observations uncover merger process in a nearby low-mass galaxy cluster
Using NASA's Chandra and ESA's XMM-Newton spacecraft, an international team of astronomers have performed X-ray observations of a nearby low-mass galaxy cluster designated PSZ2 G181.06+48.47. The observational campaign, detailed in a paper published Jan. 13 on the pre-print server arXiv, uncovers essential information regarding the nature and properties of this cluster.

XMM-Newton catches giant black hole’s X-ray oscillations
The European Space Agency's XMM-Newton has detected rapidly fluctuating X-rays coming from the very edge of a supermassive black hole in the heart of a nearby galaxy. The results paint a fascinating picture that defies how we thought matter falls into such black holes, and points to a potential source of gravitational waves that ESA’s future mission, LISA, could see. XMM-Newton is showing us that black holes devour matter in more complex ways than astronomers first thought. Black holes are predictions of Albert Einstein’s theory of general relativity. They are gravitational monsters that imprison any piece of matter or energy that crosses their ‘surface’, a region of spacetime known as the event horizon.
