Latest INTEGRAL Stories
Four years of observations from the European Space Agencyâ€™s Integral satellite may have cleared up one of the most vexing mysteries in our Milky Way: the origin of a giant cloud of antimatter surrounding the galactic center.
Astronomers from around the world have been discussing the extraordinary scientific riches that have flowed from ESAâ€™s orbiting gamma-ray observatory, Integral. Here we present the gist of some of the astonishing ones.
With eyes that peer into the most energetic phenomena in the universe, ESAâ€™s Integral has been setting records, discovering the unexpected and helping understanding the unknown over its first five years.
Integral's latest survey of the gamma-ray universe continues to change the way astronomers think of the high-energy cosmos. Astronomers have been able to construct the largest catalogue yet of individual gamma-ray-emitting celestial objects.
If a satellite encounters high-energy particles or other 'space weather' phenomena before ground controllers can take action, on-board electronics could be disrupted, scientific instruments damaged and, in very rare and extreme cases, spacecraft may even be lost.
ESA's gamma ray observatory Integral has caught the centre of our galaxy in a moment of rare quiet. A handful of the most energetic high-energy sources surrounding the black hole at the centre of the Galaxy had all faded into a temporary silence when Integral looked.
ESA's gamma-ray observatory, Integral, has spotted a rare kind of gamma-ray outburst. The vast explosion of energy allowed astronomers to pinpoint a possible black hole in our Galaxy.
Astronomers using ESA's orbiting gamma-ray observatory, Integral, have taken an important step towards estimating how many black holes there are in the Universe.
Scientists on a quest to find hidden black holes in the local universe have found surprisingly few. The observation implies that if these hidden black holes exist---and most scientists are convinced they do---they must be from the more distant, earlier universe, a concept that has interesting implications for galaxy evolution.
Thanks to a clever piece of design and a sophisticated piece of analysis by European astronomers, Integral - ESAâ€™s orbiting gamma ray observatory - can now make images of the most powerful gamma-ray bursts even if the spacecraft itself is pointing somewhere completely different.
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...
