Jets of particles and gamma radiation are emitted in opposite directions from the stellar core as the star collapses. In this model, a narrow beam of gamma rays is emitted, followed by a wider beam of gamma rays. The narrow beam for GRB 080319B was aimed almost precisely at the Earth, which made it the brightest gamma-ray burst observed to date by NASA's Swift satellite. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/twoComponentJetStream_960x540/twoComponentJetStream_960x540.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
