A rapidly rotating supermassive black hole has been found in the heart of a spiral galaxy by ESA's XMM-Newton and NASA's NuSTAR space observatories, opening a new window into how galaxies grow.

ESA's XMM-Newton space observatory has completed the most detailed study ever of the fierce wind from a giant star, showing for the first time that it is not a uniform breeze but is fragmented into hundreds of thousands of pieces.

Monitoring a pulsar with XMM-Newton, astronomers discovered X-ray variations that mimic in reverse similar changes seen in radio waves. This switching behaviour, which occurs within only a few seconds, challenges the current understanding of pulsars.

Studying the Andromeda galaxy with XMM-Newton, astronomers have discovered a black hole accreting mass at very high rate. This allowed them to study the link between disc and jets around a black hole at the peak of its accretion activity.

Data from INTEGRAL and XMM-Newton have helped astronomers study how neutron stars accrete mass in highly obscured X-ray binaries. The results suggest a new method to estimate the mass of neutron stars.

Ground- and space-based observations, including studies by ESA's XMM-Newton X-ray observatory, have provided unique insights into a star system dominated by two Galactic giants.

Astronomers using XMM-Newton and Suzaku have detected the final signal sent by the debris of a disrupted star before it disappeared beyond the event horizon of a distant, supermassive black hole.

An international team of scientists has used the world's most powerful X-ray observatories - including ESA's XMM-Newton orbiter - to probe the dusty surroundings of a newborn star and discover some of its innermost secrets.

Astronomers studying the galaxy NGC 4151 have detected X-rays emitted and then reflected from the vicinity of the supermassive black hole at the galaxy's core, thus revealing the black hole's vicinity in unprecedented detail.

Astronomers have discovered that black-hole driven ultra-fast outflows are common in active galaxies, and they are massive and powerful enough to provide the feedback required by galactic evolution models.

Astronomers have used XMM-Newton and other telescopes to uncover an unusually slow X-ray pulsar still nestled in the remains of the supernova that created it.

Astronomers using XMM-Newton have captured a neutron star undergoing a rare, intense flare, which may have been produced when the star ingested a massive clump of matter.

Astronomers working with data from several observatories, including ESA's XMM-Newton, have discovered the most distant, mature galaxy cluster yet.

Two ESA observatories have combined forces to show the Andromeda Galaxy (M31) in a new light. Herschel sees rings of star formation in the most detailed image of M31 ever taken at far-infrared wavelengths, and XMM-Newton shows X-rays from dying stars.

Observing the X-ray-bright gas in the halo of the Milky Way, ESA's XMM-Newton has gathered new data which favour a process involving fountains of hot gas in our Galaxy.

Astronomers using XMM-Newton and other world-class X-ray telescopes have probed a curious source, which emits flares and bursts just like a magnetar but lacks the extremely high external magnetic field typical of these objects.

A long-sought-after emission line of oxygen, carrying the imprint of strong gravitational fields, has been discovered in the XMM-Newton spectrum of an exotic binary system.
