NASA's Fermi, Swift See 'Shockingly Bright' Burst

The maps in this animation show how the sky looks at gamma-ray energies above 100 million electron volts (MeV), with a view centered on the north galactic pole. The first frame shows the sky during a three-hour interval prior to GRB 130427A. The second frame shows a three-hour interval starting 2.5 hours before the […]
