After a nearly twenty-year long game of cosmic hide-and-seek, astronomers using ESA's XMM-Newton space observatory have finally found evidence of hot, diffuse gas permeating the cosmos, closing a puzzling gap in the overall budget of 'normal' matter in the Universe.

ESA's XMM-Newton observatory has discovered the best-ever candidate for a very rare and elusive type of cosmic phenomenon: a medium-weight black hole in the process of tearing apart and feasting on a nearby star.

ESA's XMM-Newton observations of a neutron star merger, obtained a few months after its discovery via gravitational waves, caught the moment when its X-ray emission stopped increasing, opening new questions about the nature of this peculiar source.

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?

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. The team has now used ESO's Very Large Telescope to find that the star boasts a strong magnetic field, confirming its status as a cosmic lighthouse.

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.

ESA and NASA space telescopes have revealed that, unlike Earth's polar lights, the intense auroras seen at Jupiter's poles unexpectedly behave independently of one another.

Proposals are solicited for observations with XMM-Newton in response to the seventeenth Announcement of Opportunity, AO-17, issued 22 August 2017. This AO covers the period May 2018 to April 2019 and is open to proposers from all over the world. The deadline for proposals is 6 October 2017 (12:00 UTC).

ESA and NASA space telescopes have made the most detailed observation of an ultra-fast wind flowing from the vicinity of a black hole at nearly a quarter of the speed of light.

ESA's XMM-Newton has found a pulsar – the spinning remains of a once-massive star – that is a thousand times brighter than previously thought possible.

Scientists observing a curious neutron star in a binary system known as the 'Rapid Burster' may have solved a forty-year-old mystery surrounding its puzzling X-ray bursts.

A giant bubble surrounding the centre of the Milky Way shows that six million years ago our Galaxy's supermassive black hole was ablaze with furious energy. It also shines a light on the hiding place of the Galaxy's so-called 'missing' matter.

Proposals are solicited for observations with XMM-Newton in response to the sixteenth Announcement of Opportunity, AO-16, issued 23 August 2016. This AO covers the period May 2017 to April 2018 and is open to proposers from all over the world. The deadline for proposals is 7 October 2016 (12:00 UT).

ESA's orbiting X-ray observatory, XMM-Newton, has proved the existence of a 'gravitational vortex' around a black hole. The discovery, aided by NASA's NuSTAR mission, solves a mystery that has eluded astronomers for more than 30 years and will allow them to map the behaviour of matter very close to black holes.

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.

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.
Published: 31 March 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.

The first papers from the XXL survey, carried out with ESA's XMM-Newton X-ray observatory, are published in a special issue of Astronomy and Astrophysics today. This is the largest XMM-Newton survey of galaxy clusters ever undertaken and the first results reveal the enormous potential of this survey.
