Tiny stellar 'corpses' have been caught blasting surprisingly powerful X-rays and gamma rays across our galaxy by ESA's gamma-ray observatory Integral.
Cosmic space is filled with continuous, diffuse high-energy radiation. To find out how this energy is produced, the scientists behind ESA's Integral gamma-ray observatory have tried an unusual method: observing Earth from space.
ESAâ€™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.
Observing the cosmos, full of violent phenomena and extreme energy, has been the task of ESAâ€™s Integral gamma-ray observatory since its launch on October 17, 2002. Three years later, the mission is going very well and has recorded a wealth of important discoveries.
An international team of scientists has uncovered a rare type of neutron star so elusive that it took three satellites to identify it.
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.
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...
