Poster focuses on Poltergeist, Draugr and Phobetor, three planets that orbit the pulsar PSR B1257+12, which lies about 2,000 light-years from Earth. Pulsars are fast-spinning stellar corpses that emit beams of radiation from their poles; these beams appear to pulse because of the rotation, which gives pulsars their name.
This powerful radiation bathes Poltergeist, Draugr and Phobetor, making life as we know it impossible on the worlds, NASA officials said.
Posters were created by NASA’s Exoplanet Exploration Program Office, which is based at the Jet Propulsion Laboratory (JPL) in Pasadena, California.
