 "GRB 130427A was a record-setting Gamma-ray burst, discovered starting on April 27, 2013.[1][2][3] The Fermi space observatory detected a gamma-ray with an energy of at least 94 billion electron volts.[1] It was simultaneously detected by the Burst Alert Telescope aboard the Swift Gamma-Ray Burst Mission and was one of the brightest bursts Swift had ever detected.[1] It was one of the five closest GRBs, at about 3.6 billion light-years away, and was comparatively long-lasting.[1]"
