Project PHaEDRA - Adelaide Ames - [Diameter, Circumference] Coma-Virgo, 6. #G25 (phaedra2316)
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; 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 Adelaide Ames who was the observatory's first graduate student and known for her surveys of spiral galaxies, then called extra-galactic spiral nebulae. Interested in the history of science? Love astronomy? Help us transcribe the work of the Harvard Observatory's women computers and early astronomers and see which stars shine the brightest. PLEASE NOTE: Project PHaEDRA notebooks are quite unique, and we have a special set of instructions for them. Please take a moment to familiarize yourself with these guidelines.

Project PHaEDRA - Annie Jump Cannon - Annie Cannon Notebooks #119
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.
