The COS-B satellite was the Âfirst to detect an extragalactic source emitting in this regime, while the OSO-7 satellite providedthe Âfirst recording of the solar spectrum in this regime; in the sun, radiation in this regime is emitted from de-excitation of deuterium.The Solar Maximum Mission measured the spectrum of this radiation during the explosion of supernova SN1987A.The strongest source in the sky for radiation in this regime is the Crab Nebula. A typical mechanism of generating this radiationin supernovae is the decay of cobalt-56, and this type of radiation is also generated by matter accretion around blackholes and neutron stars. Mechanisms suspected of generating the most intense radiation in this regime, as measured by the BeppoSAX satellite, include neutron star or black hole collisions, resulting in the emission of this radiation via the relativisticfiÂreball model. The predominant form of radiation in blazars, for 10 points, identify this frequency regime which contains themost powerful photons known, and which is detected in the spectrum of its namesake "bursters."
