WebThe vast majority of white dwarfs are formed after a dying star has shed its outer layers to form a planetary nebula, leaving behind an approximately Earth-sized inner core that is the white dwarf. Other white dwarfs in binary systems may explode as novae but then not go on to form a neutron star or a black hole.

WebAs the hydrogen runs out, a star with a similar mass to our sun will expand and become a red giant. When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant. While most stars quietly fade away, the supergiants destroy themselves in a huge explosion, called a supernova.
