Happy birthday to #astrophysicist Jocelyn Bell Burnell! In 1967, as a grad student she discovered the 1st radio pulsar, a highly magnetized, rotating neutron star that emits a beam of EM radiation. This radiation can only be observed when the star is pointed towards us; so, like the light from a lighthouse, it appears to pulse at a precise frequency. She had been working with her supervisor Hewish & others to construct a radio telescope to study quasars. 🧵1/n
