A pulsar (short for pulsating radio star) is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation.
To an observer, a pulsar appears as a signal in a radio telescope; the signal can be picked up over a broad band of frequencies on the dial (In this exercise, you can tune the receiver from 400 to 1400 MHz). The signal is characterized by short bursts of radio energy separated by regular gaps.
