Zombie Worlds
Although they were among the first exoplanets to be discovered, these alien worlds were doomed from the start.
Psr b1257+12 is a zombie star system, with two planets orbiting a pulsar. A pulsar is a fast rotating dead star, or neutron star, which is the super-dense remains of a star that collapsed in a supernova. These stars emit beams of radiation that render nearby planet uninhabitable.
