#OnThisDay, 24 Feb 1968, Jocelyn Bell Burnell - along with her male supervisor and three other men - published a paper confirming the discovery of pulsars. She had built the array, picked up the signal and argued it was not an anomaly. Hewish received the Nobel prize for it in 1974: Bell Burnell did not.

In 2018 Bell Burnell received a £3m prize for her work. She's used it to set up a foundation to improve the diversity in STEM.
