Astronomers have confirmed what’s at the centre of a supernova, the violent explosive deaths of massive stars.
Stars die as they exhaust the fuel required for driving the nuclear reactions that enable their illumination. However, astronomers suggest that a huge stellar mass causes the gravitational force to destroy the atoms, forming either a neutron star or, for larger stars, a black hole.
