Core Collapse Supernova

A core collapse supernova is a violent explosion caused by the death of a massive star. While massive stars can sustain fusion reaction in its core beyond hydrogen fusion, stellar nucleosynthesis cannot proceed further than iron, as the energy required to fuse iron into a heavier element is greater than the energy that is produced from the fusion. As the star is thrown off its thermal equilibrium, the star goes through a titanic explosion, releasing all of its material in the vicinity. A neutron star or a black hole is usually left behind from a core collapse supernova.
