How was the crab pulsar discovered?

The Crab Pulsar was discovered in 1968 by astronomers Jocelyn Bell Burnell and Antony Hewish while they were studying radio emissions from the Crab Nebula, the remnant of a supernova explosion. They detected regular pulses of radio waves at a frequency of about 30 times per second, which were later identified as coming from a rapidly rotating neutron star. This pulsar was significant as it provided key insights into the physics of neutron stars and the nature of pulsars. The discovery was notable not only for its scientific importance but also for the innovative techniques used in radio astronomy.
