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...

INTEGRAL's all-sky map of the 511 keV line emission has been used to conclude that dark matter is not the origin of galactic positron annihilation, contrary to what had been assumed in past years.

The quick turn-around time of the INTEGRAL operation teams has enabled rare high-energy observations of a magnetar. The observations followed indications late last week that 1E 1547.0-5408 was in outburst mode.

An analysis of the 47 gamma-ray bursts detected by INTEGRAL since its launch reveals a previously unnoticed population of faint gamma-ray bursts associated with the local supergalactic structure.

INTEGRAL's detection of polarized gamma-rays from the Crab pulsar, reported in the 29 August issue of Science, has significant implications for many aspects of high-energy accelerators.

Eta Carinae is a complex binary system, at a distance of around 8000 light years, with a large nebulosity surrounding the central objects. Observations with INTEGRAL have confirmed the nature of hard X-ray emission from the region to be from inverse compton scattered photons accelerated in a region where two stellar winds collide.

At their 12-13 November meeting, ESA's Science Programme Committee has unanimously approved an extension for the INTEGRAL mission which pushes back the end date from 16 December 2010 to 31 December 2012.

The launch of INTEGRAL five years ago heralded a new era in gamma-ray observatories. Utilising solid-state detectors and coded mask imaging techniques, INTEGRAL was unlike any previous gamma-ray mission.
