Life Cycle Of A Star
From the formation of a protostar the doom of a star.
Life Of Star:
The Good Life
Now That The Star Is Dying:
The Star Will Start to expand, as the gases wear off from the dense core, which are still every hot, and will incinerate any plants in the close vicinity.
Some stars will explode in a supernova, which happens when a star's core finally collapses, and explodes. It makes the rest of the star also explode. Or, it could make a gamma ray burst, which is when gamma rays are ejected from the star violently. Or, the star will collapse in on itself and become a violently hot, yet very dim, white dwarf.
It's possible that if a very large star collapses in a very violent way, that a black hole will be formed. Black holes have infinite density, and will tear apart anything near it, and suck it into the black hole.
