The International Gamma-Ray Astrophysics Laboratory - INTEGRAL for short - was launched from Baikonur in Kazakhstan earlier today. The observatory will be able to detect high-energy gamma-ray photons from a variety of astrophysical sources such as supernovae, black holes, neutron stars and gamma-ray bursts. INTEGRAL will be placed into a highly eccentric 72-hour orbit and will spend most of its time at altitudes in excess of 40000 kilometres, well beyond the Earth’s radiation belts.
