Henrietta Leavitt discovered the relation between the period and luminosity of cepheid variable stars. By using Henrietta's discovery, astronomers can estimate the distances to these stars and thus to their home galaxies. Her discovery became one of the foundations of modern cosmology.

  • Women crop up everywhere in science history, but are only recently being celebrated. Thanks for this lovely introduction to Henrietta and the "computers" (or is it "computors"?) , the women who worked in droves pouring over raw data and photos for so long.

  • This is a good video that's very informative !!

  • Hi!

    As a physicist, I believe than Henrietta made a great... enormus descovery, but as a woman, it's sad to se that she is inly a shadow in this science. There is no way of knowing what other contributions she would have made had she not died so young. Thanks for the video! help me with my homework of astrophysicist! LOL
