Black dwarf
stellar remnant; white dwarf that has cooled sufficiently to no longer emit significant light / From Wikipedia, the free encyclopedia
A black dwarf is a kind of star. A black dwarf is made when a white dwarf star becomes too cold. When it is cold enough, it can no longer make large amounts of heat and light. The star will get darker and become black. Scientists are not certain if black dwarfs can exist because it takes longer than the age of the universe (13.8 billion years) for a white dwarf to become one.
