Gamma-ray burst (GRB 080319B), artwork. GRBs are extremely high-energy events that may be the result of a neutron star being torn apart by a black hole. This GRB occurred around 7.5 billion light years from Earth, in the constellation Bootes, observed on 19 March 2008 by the Swift Gamma-Ray Burst Mission. It was so intense that it was briefly the most distant object visible to the naked eye. It consisted of a narrow jet and a wider jet (both shown here), with similar jets emerging from the star's other pole. The brightness of this event was due to the narrow jet pointing directly at Earth.Restrictions:.
