Pulsars

Neutron stars spin rapidly giving off radio waves. If the radio waves appear to be emitted in pulses (due to the star's spin), these neutron stars are called pulsars.

In 1974, the Nobel Prize in physics was jointly awarded to astronomers Antony Hewish and Sir Martin Ryle. Antony Hewish was honored for the discovery of pulsars. Many have argued that Jocelyn Bell Burnell should have shared that honor.

Pulsars are dense remnants of dead stars that regularly emit beams of radio waves, which is why some call them "cosmic lighthouses."
