Astronomers do not believe the Sun will end its life cycle as a black hole because it is not massive enough. Stars need to have a certain mass, typically more than about 20 times the mass of the Sun, to end their lives as black holes. The Sun, which is a middle-sized star, is expected to transform into a red giant and eventually shed its outer layers, leaving behind a white dwarf.
