How does a super nova form?

A supernova doesn't really form; rather it is a happenstance (I love that word!). To describe supernovae I would say the word BOOM(!) suffices. Basically, it's a explosion of a star. It's that simple. Of supernova there are two main types: Type 1a & Type 2 SN (supernova).

Type 1a:
Is when a white dwarf accretes mass (most often a binary partner) and reaches the Chandrasekhar Limit (which is the limit to the mass of white dwarfs {1.39 Solar Masses}). Electron degeneracy pressure can't hold the star together (there are no fusion reactions to hold the star up- electron degeneracy pressure does {don't worry about this}). The star blows up. Happy birthday.

Type Two:
Only stars at least eight times the mass of the sun can explode this way. They do this when there cores can no longer fuse enough or fuse at all, they collapse. Then, through a complicated process, they explode.
