Supernova explosion,computer artwork. Supernovas are the explosive deaths of massive stars. A supernova will occur when a star runs out of fuel at the end of its life. Without the nuclear reactions that powered it,it can no longer support itself against gravity,and it collapses. When it reaches a critical density,the outer layers rebound off the super-dense core in an enormous explosion,leaving the core exposed as a neutron star | |
