INTEGRAL Latest News

INTEGRAL science operations confirmed until 31 December 2016 and indicatively extended until 31 December 2018

24 November 2014 During a meeting on 19 & 20 November 2014, the Science Programme Committee (SPC) approved the confirmation of science operations until 31 December 2016, as well the indicative extension of science operations for INTEGRAL until 31 December 2018, subject to a mid-term review in 2016. The aim is to reduce the allocated resources for 2017/2018 by approximately 10% as compared to 2016. See the full story on the SPC decision.

This is excellent news for INTEGRAL and the science community. We thank you for your continuing support.



17 October 2014 Twelve years ago, on 17 October 2002 at 6:41 CEST, the INTEGRAL observatory was launched from Baikonur. Today, it still remains in excellent health and continues to observe the gamma-ray and X-ray sky.

SN2014J: INTEGRAL catches dead star exploding in a blaze of glory

27 August 2014 Astronomers using INTEGRAL have demonstrated beyond doubt that dead stars known as white dwarfs can reignite and explode as supernovae. The finding came after the unique signature of gamma rays from the radioactive elements created in these explosions was captured for the first time in SN2014J. See the story in the ESA press release.

10th INTEGRAL Workshop: deadlines reduced-fee registration and low hotel rate extended; workshop program available

14 August 2014 The 10th INTEGRAL Workshop "A Synergistic View of the High Energy Sky" will take place from 15-19 September 2014, in Annapolis, MD, USA. The deadline for the reduced-fee registration has been extended to August 22. The low hotel rate for the reserved block has been extended to August 29. Also, the Workshop program is now available. For more information we refer to the Workshop web page at

Update (19 Aug 2014): Links to the hotel room reservations page which were included in the 2nd and 3rd Circulars were changed by the hotel staff, so if you want to go to their new, dedicated page please use the new connection: NASA - Integral Workshop. Also, we would like to draw your attention to the check-out date. With the old form the nominal check-out was Thursday and not Friday (we adjourn around lunch time on Friday), so an extra booking was likely required. The new link has corrected that, but please check your reservation confirmation sent to you from the hotel, and make sure you have the check-out date correct.

INTEGRAL TOO observations of Mkn 501 in outburst

5 August 2014 Mkn 501 has been active now for several months. It displays very strong flaring activity, which has been detected in soft X-rays by Swift/XRT and in gamma-rays by MAGIC. INTEGRAL will also observe the active source during revolution 1443, when a TOO observation of 200 ksec has been accepted by the INTEGRAL Project Scientist.

Early 56Ni decay Gamma rays from SN2014J suggest an unusual explosion

1 August 2014 INTEGRAL has revealed a surprising signal of gamma-rays from the surface of material ejected by the supernova explosion in SN2014J. This result challenges the prevailing explosion model for type Ia supernovae, indicating that such energetic events might be ignited from the outside as well - rather than from the exploding dwarf star's centre. The findings are reported in Science Express.

INTEGRAL AO-12 General Programme approved

2 July 2014 The INTEGRAL AO-12 General Programme, as recommended by the Time Allocation Committee (TAC) and approved on June 12 by ESA's Director of Science and Robotic Exploration (Prof. Alvaro Giménez), has been released and the observers have been informed.
