Project PHaEDRA - Annie Jump Cannon - Annie Cannon Notebooks #177
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 the new instructions.

Project PHaEDRA - Muriel & Sylvia Mussells - MC Classification and Diameters #G132
At Harvard College Observatory (now the Center for Astrophysics | Harvard & Smithsonian), Women Astronomical Computers studied glass plate photographs of the night sky. Here they cataloged stars, identified variables, interpreted stellar spectra, counted galaxies, and measured the vast distances in space. Several of them made game-changing discoveries in astronomy and astrophysics. In these books, you can follow the work of Sylvia and Muriel Mussells, two sisters who worked at the Harvard College Observatory in the 1920s and 1930s. Muriel Mussells discovered three new ring nebulae in the Milky Way and Sylvia Mussells discovered the first dwarf galaxy. You can help us find out what else we can learn about them and their work!
