Jocelyn Bell Burnell

Biography

Jocelyn Bell Burnell discovered pulsars as a graduate student at Cambridge in 1967, spotting an impossibly regular radio signal her team nicknamed 'LGM-1'. The pulses turned out to be rotating neutron stars — one of the great discoveries of 20th-century astronomy. The 1974 Nobel Prize for the work went to her supervisor; in 2018 she received a Special Breakthrough Prize, donating its $3 million to support under-represented physics students.
