Fading light of one of the brightest gamma-ray bursts ever seen

NASA Swift's ultraviolet-detecting telescope (the UVOT) captured the fading light of one of the brightest gamma-ray explosions ever seen, named GRB 130427A, using images acquired through filters that correspond to energies of 4.7 and 6.1 electron volts. The movie begins about 6 minutes after the burst triggered Fermi's gamma-ray-burst monitor and lasts until 10.3 days after. The angular width of the movie is 100 arcseconds. Duration: 11.5 seconds
