Collapse of a massive star. Artwork (image 5 of 7) showing the supernova remnant following the collapse of a Wolf-Rayet star (a stage in the evolution of a very massive star). The core of the Wolf-Rayet star has collapsed, forming a black hole surrounded by a disk of accreting matter (centre). Within a few seconds, jets of matter (white) are ejected at near the speed of light, shattering the star in a supernova event and generating a radiation burst. Over the course of many years, a supernova remnant of ejected material emerges (red). Observations of a very energetic supernova, associated with a long gamma-ray burst (GRB 030329) in the constellation Leo on 29 March 2003, provide evidence for this collapsar model of the origin of some gamma-ray bursts.
