Hypernova stage. Cutaway artwork showing one of the stages in the explosion of a massive star, known as a hypernova. A hypernova is a long-lived supernova, also known as a pair-instability supernova. This stage shows the outward radiation pressure balancing the inward gravitational force (arrows), preventing the star from collapsing. This type of supernova blasts the entire star into the surrounding space, unlike ordinary supernovas that leave a neutron star or black hole. This artwork and sequence (C002/3781 to C002/3785) are based on supernova SN2006GY.
