"This illustration shows the positions of 1,000 Swift GRBs on an all-sky map oriented so that the plane of our galaxy, the Milky Way, runs across the centre. Bursts are colour coded by year, and the location of GRB 151027B is shown at lower right. An annual tally of the number of bursts Swift has detected appears below the label for each year. Background: An infrared view from the Two Micron All-Sky Survey." Caption and image credit: NASA's Goddard Space Flight Centre and 2MASS/J. Carpenter, T. H. Jarrett, and R. Hurt
