Without her, we wouldn\u2019t have a three-dimensional sky. Leavitt\u2019s Law allowed us to measure distances in other galaxies as early as 1912. But how many people have ever heard of Henrietta Leavitt? We wanted to know about this \u2018hidden woman\u2019 of astronomy, so in this episode of the Big Questions podcast we ask Dr Becky Smethurst from the University of Oxford\u2019s Department of Physics \u201cWho was Henrietta Leavitt?\u201d.
