In 1967 Jocelyn Bell Burnell helped discover pulsars as part of her PhD in Radio Astronomy at Cambridge University. Not bad considering she and her team built the radio telescope she used! She is one of Britain's most distinguished female scientists, having worked at the University of Southampton, University College London and the Royal Observatory in Edinburgh. She has used telescopes flown on high-altitude balloons, launched on rockets and carried on satellites. From time to time she can be found in Hawaii - panting for breath at 4,250 metres and using the UK's infrared or millimetre band telescopes.
