And white dwarfs, they're the contact remains of dead sunlight stars, and they're all through the universe. The Milky Way alone has hundreds of millions of them. Our Sun one day, once it exhausts its hydrogen supply, it will collapse into a white dwarf. It's not big enough, it doesn't have enough mass to collapse into a neutron star, it will on a black hole, but it will one day collapse into a white dwarf once it's exhausted its fuel.
