GRB 050709


Gamma-ray bursts longer than two seconds are the most common type and are widely thought to be triggered by the collapse of a massive star into a black hole. As matter falls toward the black hole, some of it forms jets in the opposite direction that move near the speed of light. These jets bore through the collapsing star along its rotational axis and produce a blast of gamma rays after they emerge. This artist's rendering depicts a GRB that was discovered on July 9, 2005, by NASA's High-Energy Transient Explorer (HETE).
