Project PHaEDRA - Annie Jump Cannon - Annie Cannon Notebooks #94

At Harvard College Observatory (now the Harvard-Smithsonian Center for Astrophysics), Women Astronomical Computers studied glass plate photographs of the night sky. Here they cataloged 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. In these books, follow the work of Annie Jump Cannon, who in 1901 devised a robust and elegant stellar classification scheme that astronomers still use today. 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. PLEASE NOTE: The Project PHaEDRA Instructions for Women Computers Notebooks were heavily revised and republished on August 18, 2023. Please take a moment to familiarize yourself with these instructions.
