Crab Nebula Pulsar: Credits and Copyright

The pulsar in the Crab is thought to be a rapidly spinning neutron star with a strong magnetic field. Radiation may escape along the directions of the field. As the pulsar spins, X-rays are emitted in short bursts like flashes from a cosmic lighthouse. When the observations are timed to match these pulsations, the Crab's pulsar seems to turn on and off.
