Gamma ray burst (GRB) 110328A, Hubble image. GRBs are extremely high-energy events that occur when a star is torn apart by powerful jets that form as it collapses. These events occur rapidly, but the afterglow can be recorded by sensors on orbiting satellites. GRB 110328A was detected on 28 March 2011 and flared several times over the following days. This image of the GRB's host galaxy (arrowed) was obtained by NASA's Hubble Space Telescope's Wide Field Camera 3 on 4 April 2011. GRB 110328A is 3.8 billion light years from Earth, in the constellation of Draco.
