11/20/2014: Integral mission extension to December 2016 confirmed by ESA's Science Programme Committee.
08/28/2014: Discovery of 56Co gamma ray emission from a Type Ia supernova with the Integral observatory.
Analysing the observations of the type Ia supernova SN2014J with the SPI spectrometer and the ISGRI / IBIS imager on the Integral space observatory (International Gamma-Ray Laboratory of the European Space Agency), a team of researchers, including researchers from France, has discovered low-energy gamma-ray emission lines (photons between 100 keV and 10 MeV). This is the first time that such radiation has been observed from this type of supernova.
06/19/2013: Debris from stellar explosions in the Galaxy's fast lane.
A team lead by Karsten Kretschmer from the Astroparticules et Cosmologie (APC) laboratory, supported by CNES, analysed the observations made by the SPI spectrometer on ESA's Integral gamma-ray observatory to measure the surprisingly high velocity of the hot gas ejected by massive stars into the inner regions of the Milky Way.

03/2013: High-mass X-ray binaries trace the Milky Way's spiral arms
Observations of high-energy phenomena, in particular with the Integral spacecraft, have discovered numerous massive X binary sources in the Milky Way. While more than 200 are catalogued, until now their locations have not been fixed very precisely. By measuring exactly the distance of a sample of 50 such sources, two researchers from the Service d'Astrophysique-Laboratoire AIM du CEA-Irfu in Saclay, supported by CNES, showed that these sources are in a cluster of 1,000 light years located in the star formation complexes in the spiral arms of the Milky Way. Their work, published in The Astrophysical Journal, provides new insight into the environment where these systems were born and evolved.
10/2012: Integral is ten years old...
ESA's Integral mission is celebrating the 10th anniversary of its launch, which occured on 17 October 2002. Over the past decade, the mission has observed the entire sky at hard X-ray and soft gamma-ray energies with unprecedented sensitivity and resolution, shedding new light on several classes of astronomical sources, galactic and extragalactic alike. Highlights of the mission so far have included the study of the emission from electron-positron annihilation across the sky, the discovery of two previously unknown classes of X-ray binaries, the characterization of the cosmic X-ray background and the first detection of polarization in gamma-ray sources.
