Professor Dame Jocelyn Bell Burnell discovered pulsars in 1967 while she was a postgraduate student at New Hall (now Murray Edwards College) carrying out research at Cambridge’s Cavendish Laboratory with Antony Hewish.
Who first discovered the radio wave pulses from pulsars?
Anthony Hewish won the Nobel Prize in 1974 for the discovery of the first pulsars. Over 1000 pulsars are now known.

How and who discovered pulsars and quasars?
When Dame Jocelyn Bell Burnell discovered the first pulsar 51 years ago, she revealed a new tool for solving many mysteries of the cosmos.
Who discovered quasars?
British-Australian astronomer John Bolton made many early observations of quasars, including a breakthrough in 1962. Another radio source, 3C 273, was predicted to undergo five occultations by the Moon.

What is a pulsar who discovered the first pulsar originally called LGM’s?
Anthony Hewish, to make radio observations of the universe. Bell and Hewish had no idea what the signals were that they detected, so they were dubbed little green men (LGM) as a reference to extraterrestrial life. Soon after, Thomas Gold showed that a spinning neutron star could make the pulses they observed.

How many pulsars have been discovered?
Over 2,000 pulsars have been detected in total. Most of those rotate on the order of once per second (these are sometimes called “slow pulsars”), while more than 200 pulsars that rotate hundreds of times per second (called “millisecond pulsars”) have been found.
