Recently it has been proposed that they may be the source of high-energy cosmic ray positrons observed by the Pamela, ATIC, and Fermi-LAT experiments, which would require nearby ones like B0656+14 or Geminga.

The first extrasolar planets to be discovered, in 1992, were found orbiting one in the Virgo constellation. They typically have magnetic fields of order a trillion gauss. A very young one, produced during the SN 1054 supernova, had an initial rotational energy of around 10 to the 50 ergs and lies at the center of the Crab Nebula. The first observation of one was made at the Mullard Radio Astronomy Observatory in 1967, by Jocelyn Bell and Antony Hewish. For 10 points, what are these rapidly rotating neutron stars that emit regular bursts of radiation?
