The Life Scientific: Jocelyn Bell-Burnell

Jim al-Khalili talks to the astronomer Jocelyn Bell Burnell about missing out a Nobel Prize, sexism in science and a strange smudge in the data from a radio telescope. While others dismissed this smudge as insignificant, Jocelyn revealed a series of strange flashing signals. They might have been evidence of faulty radio telescope or even messages from a little green man; but Jocelyn thought otherwise and her determination to get to the bottom of it all, led to one of the most exciting discoveries in 20th century astronomy, the discovery of pulsars, those dense cores of collapsed stars.
