ESA -- ESA's Science Programme Committee has extended operations of the highly successful astronomical observatories Integral and XMM-Newton for four years, until 16 December 2010 and 31 March 2010 respectively. As usual, there will be a review of the scientific performance and of the missions status in another two years' time, around autumn 2007. The Integral gamma-ray observatory was launched on 17 October 2002, and has been providing ever since an increasingly detailed insight into some...

ESA -- Observing the cosmos, full of violent phenomena and extreme energy, has been the task of ESA's Integral gamma-ray observatory since its launch on 17 October 2002. Three years later, the mission is going very well and has recorded a wealth of important discoveries. Integral is surveying the sky continuously using four instruments "“ two main gamma-ray instruments dedicated to imaging (IBIS) and spectroscopy (SPI), an X-ray instrument (JEM-X) and an optical monitor (OMC)....

ESA -- An international team of scientists has uncovered a rare type of neutron star so elusive that it took three satellites to identify it. The findings, made with ESA's Integral satellite and two NASA satellites, reveals new insights about star birth and death in our Galaxy. We report this discovery, highlighting the complementary nature of European and US spacecraft, on the day in which ESA's Integral celebrates 1000 days in orbit. The neutron star, called IGR J16283-4838, is an...

The center of our galaxy has been known for years to host a black hole, a 'super-massive' yet very quiet one. New observations with Integral, ESA's gamma-ray observatory, have now revealed that 350 years ago the black hole was much more active, releasing a million times more energy than at present. Scientists expect that it will become active again in the future. ESA -- Most galaxies harbour a super-massive black hole in their center, weighing a million or even a thousand million times more...

Gamma-Ray Astronomy -- Gamma-ray astronomy is the astronomical study of gamma rays. Long before experiments could detect gamma rays emitted by cosmic sources, scientists had known that the universe should be producing these photons. Work by Feenberg and Primakoff in 1948, Hayakawa and Hutchinson in 1952, and, especially, Morrison in 1958 had led scientists to believe that a number of different processes which were occurring in the universe would result in gamma-ray emission. These...
