Prior to this observation, intense transient bursts of gamma rays were only known to occur in an astrophysical context. These powerful rays are part of the electromagnetic spectrum, produced by the hottest and most energetic objects in the universe. The spectrum uses nearly two weeks of data accumulated during the GRS initial checkout activities. And the electromagnetic radiations travel with the speed of light 300,000 m/sec in vacuum.They generate showers of secondary particles that can be detected on Earth and that point back towards the point of origin of the gamma rays. ionizing radiation properties.In a unique cosmic event, scientists have detected a burst of gamma rays originating from a rare magnetar in the nearby galaxy M82.
