20 February 2019: Born in 1868, Henrietta Leavitt was an astronomer ahead of her time, whose work helped to revolutionise our understanding of the Universe. While working at Harvard Observatory, she began to study stars of fluctuating brightness. She made a crucial observation about these objects, which gave astronomers a new way to measure distances, ultimately leading to such impactful discoveries as the expansion of the Universe. This new Hubblecast episode explores the life of Henrietta Leavitt and how her work enabled the discoveries of Edwin Hubble.
