✵✵✵✵✵What are white dwarfs? (Astronomy)
White dwarfs are dead stars that continue to glow because of heat, not nuclear fusion. Most stars in our universe will end up as a white dwarf star. Join us to learn how white dwarfs are made, what they’re like, how long they’ll shine, and how astronomers detect them.
