During a super-nova, a star explodes its outer-layers into a gaseous state. The massive explosion is triggered by the nuclear fusion in the core of the sun. The prossess of the elements fusion are hydrogen, helium, oxygen, carbon, iron, and uranium. Uranium is only found in hypergiant stars. When all of the fule is exausted, the star explodes each shell in order, until a white dwarf, nuetron star, or a black hole is left.
