In simple words, Supernova is a phenomenon which causes due to explosion of stars. Supernovas outshine the whole of the galaxy and produce enormous energy. Supernovas can happen in two ways:
1. The FIRST type of supernovas happen in Binary stars. Binary stars, name itself states there are two stars. One of the stars steal or accumulate mass from another star and due to this heavy mass, the star eventually explodes and leads to supernova.
2. The SECOND supernova :is seen only in star which are more massive than sun (8-15 solar masses). A star's life is always in equilibrium with the force excreted by the Nuclear fusion of hydrogen atoms and gravitational force excerted by star's gravity. The star's glow is only due to this nuclear fusion of Hydogen atoms to Helium atoms. When the stars run out of hydrogen atoms, the fusion reaction is stopped and the temperature rises. This rising temperature leads to production of heavier elements on the core in the below order:
Carbon
Neon
Oxygen
Silicon
Iron
Once Iron is formed, the gravity of the core collapses and it explodes which is called supernova.
But scientist think that the stars much more heavier than sun (20 - 30 solar mass) do not form supernova, but turn into Black holes.
