Bell Burnell, (Susan) Jocelyn at English => English (The Britannica Concise) Of Explained:

English astronomer. As a research assistant at Cambridge Univ., she assisted in constructing a large radio telescope and discovered peculiar pulsating radio signals that were dubbed pulsars. These were subsequently determined to be rapidly spinning neutron stars, providing the first direct evidence for the existence of the latter. The 1974 Nobel Prize was awarded for the discovery of pulsars to A. Hewish (her adviser) and M. Ryle, sparking a controversy over the omission of Bell Burnell. She subsequently became a professor at The Open University and vice president of the Royal Astronomical Society.
