Jocelyn Bell Burnell - Discovering Pulsars

As a postgraduate student, Northern Irish astrophysicist Jocelyn Bell Burnell discovered the first radio pulsars in 1967, a landmark discovery that won her supervisor the Nobel Prize in Physics in 1974, though she was controversially not included among the laureates. Pulsars, highly magnetized, rotating neutron stars, have been critical in testing the general theory of relativity and understanding the cosmos.
