Project PHaEDRA - Williamina P. Fleming - Measures of Spectrum Plates, Southern Draper Catalogue #68

About the Project

At Harvard College Observatory (now the Center for Astrophysics | Harvard & Smithsonian), women computers studied glass plate photographs of the night sky. Here they catalogued stars, identifying variables, interpreting stellar spectra, counting galaxies, and measuring the vast distances in space. Several of them made game-changing discoveries in astronomy and astrophysics. Interested in historical women? Love astronomy? Help us transcribe the work of the Harvard Observatory's women computers and see which stars shine the brightest. You can sign up for our Project PHaEDRA newsletter here. Have questions?
