White dwarf stars are formed when a sun-like star dies, puffing out its outer layers and leaving behind its exposed stellar core. This process is violent and should be the end of habitability in a system, but new simulations show that might not be true. Researchers compared the climates of hypothetical exoplanets orbiting white dwarfs. They found that rocky planets in orbit could be more habitable than previously thought.
