Harvard Observatory photographic sky survey

E541303

astronomical sky survey observational astronomy program photographic survey

The Harvard Observatory photographic sky survey was an early, pioneering program that systematically photographed the night sky, creating one of the first large-scale, long-term archives of astronomical images used for studying variable stars and other celestial phenomena.
