Black hole wakes up and has a light snack 02 April 2013 Astronomers have watched as a black hole woke up from a decades-long slumber to feed on a low-mass object - either a brown dwarf or a giant planet - that strayed too close. A similar feeding event, albeit on a gas cloud, will soon happen at the black hole at the centre of our own Milky Way Galaxy. Read more
ESA's INTErnational Gamma-Ray Astrophysics Laboratory is detecting some of the most energetic radiation that comes from space. It is the most sensitive gamma-ray observatory ever launched. INTEGRAL is an ESA mission in cooperation with Russia and the United States.
High mass X-ray binaries trace the Milky Way's spiral arms 04 March 2013 A new study of X-ray emitting binary systems of massive stars, using data from ESA's INTEGRAL space observatory, has made it possible to reconstruct the locations of the Milky Way's spiral arms many millions of years ago.

Astronomers develop new method to determine neutron star mass 09 November 2012 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. Read more
