IN BRIEF Birth: Formation of a star from a nebula. Main sequence phase: Stabilization and fusion of hydrogen into helium. Red giant: Expansion as hydrogen is depleted, the star becomes a red giant. Variable end: Depending on its mass, it may become a white dwarf or explode into a supernova. Death: Outcomes of supernova or … Read more
