When massive stars explode in violent supernovas, they wipe out any nearby planets — but sometimes, the leftovers debris from this catastrophe can cool and condense, eventually forming entirely new worlds: zombie planets, built from the ashes of the dead. 2,300 light years away, an ancient pulsar harbors 3 potential zombie worlds: Draugr, Phobetor, and Poltergeist. The intense X-ray radiation from their dead star, combined with the strobing light of the spinning pulsar poring over the surface, would make these planets appear truly alien to anyone who dares to visit.
