Assignment 21- Sheridan Wagner

Right now, at this very moment, somewhere in this universe a star is dying. Galaxies away, a star somewhere has arrived at the end of its life cycle. Its supply of hydrogen has depleted and the core can no longer be supported against the stars gravity. If it is an "ordinary" star, in will begin to form into a Red Giant, its atmosphere will expand, and nearby planets will be engulfed in flames. The core of the star, meanwhile, continues collapsing. All of this will last about 100 million years until the "ordinary" star expands even further and becomes a Red Supergiant. Eventually, the star will burn away all of its mass and leave behind a cooling core, which becomes a White Dwarf.

Or maybe the star that is currently dying happens to be a "massive" star. If this is the case, the death will be far more dramatic. This star will keep burning and collapsing until its high density core resists any further collapsing. From here, matter will begin to explode from the core producing a Supernova.
