Supernova Gamma Rays

This animation shows a model of GRB 080319B, which was visible to the naked eye despite being billions of light-years away because one jet was directed Earth’s way. Gamma-ray bursts longer than two seconds are caused by the collapse of a massive star. At the collapsing star’s center, a newborn black hole drives outward jets of particles and gamma radiation.  Credit: NASA/Swift/Cruz deWilde
