Black hole-star pair orbiting at dizzying speed 19 March 2013 ESA's XMM-Newton space telescope has helped to identify a star and a black hole that orbit each other at the dizzying rate of once every 2.4 hours, smashing the previous record by nearly an hour. Read more

Speedy black hole holds galaxy's history 27 February 2013 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. Read more

Massive stellar winds are made of tiny pieces 05 February 2013 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.

Baffling pulsar leaves astronomers in the dark 24 January 2013 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. Read more
