pre-historic, ancient, and really right up to modern times the stars have been used as a very accurate means of navigation.
Stars that are more than about three times the mass of the Sun die in a supernova explosion that usually results in a black hole. Stars smaller than that leave behind either a white dwarf or a neutron star. Since it's impossible (with our current technology) to detect black holes, scientists aren't entirely certain what the precise cutoff between black hole and neutron star is, or whether this is one of those things that could go either way depending on how it happens. We're sure that really large stars leave behind a black hole, and that smaller stars leave a white dwarf. But the in-between parts are a little hazy.
