For the first time, astronomers have caught a pulsar in a crucial transitional phase that explains the origin of the mysterious millisecond pulsars. The discovery was made possible by the coordinated efforts of ESA's two missions that scan the high-energy sky: INTEGRAL and XMM-Newton.

This Announcement of Opportunity solicits proposals for data rights on targets contained within the previously approved AO-11 observing programmes. The deadline for receipt of proposals is Friday, 4 October 2013, 14:00 CEST.

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.

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.

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.

ESA's INTEGRAL mission is celebrating the tenth anniversary of its launch and almost a decade of scanning the high-energy sky. The mission has shed new light on several classes of astronomical sources, galactic and extragalactic alike.

Astronomers using INTEGRAL have detected the first direct signature of titanium-44 in supernova remnant 1987A. The discovery reveals large amounts of this isotope, demonstrating that its decay has been powering the source for the past 22 years.

The chance discovery with ESA's INTEGRAL observatory, in 2004, of highly energetic X-rays emanating from a young neutron star with an extremely strong magnetic field, provided scientists with a challenge: to explain how these objects, also known as magnetars, produce such energetic non-thermal radiation. A new, comprehensive study of one...

Astronomers have resolved, for the first time, the Vela pulsar wind nebula in the hard X-ray band and have exploited a special imaging technique to reveal a never-before-seen component of the source.

INTEGRAL data reveal the individual processes contributing to the diffuse hard X-ray and soft gamma-ray emission produced by cosmic ray electrons in the Milky Way.

Scrutinising Active Galactic Nuclei with INTEGRAL, astronomers have found an unexpected excess of hard X-ray emission which reopens the debate on the nature of these powerful sources.

ESA's INTEGRAL gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein. It has shown that any underlying quantum 'graininess' of space must be at much smaller scales than previously predicted.

Can the powerful jets originating from the vicinity of black holes emit gamma rays? INTEGRAL observations of the X-ray binary system Cygnus X-1 have shown that they can.

Teaming up with other telescopes monitoring the Crab Nebula, ESA's INTEGRAL observatory has made a significant contribution to demonstrating that this source, previously believed to be a standard candle, might not be so reliable, after all. The small, but measurable dimming of what was until now considered to be one of the brightest and, most...

Astronomers have exploited the radioactive decay of an isotope of aluminium to estimate the age of stars in the nearby Scorpius-Centaurus association, the closest group of young and massive stars to the Sun.

Proposals are solicited for an INTEGRAL Announcement of Opportunity for obtaining data rights to targets within previously approved AO-8 observing programmes.

Astronomers have the best idea yet of how the Universe looks in gamma rays after the publication of the fourth INTEGRAL Soft Gamma-Ray Survey Catalogue. The catalogue, which has been constructed from more than 70 million seconds of observing time, now includes significantly more extragalactic sources and is set to orchestrate the future...
