Reaching beyond campus

In the spirit of the renowned Cornell Professor Carl Sagan, the Department of Astronomy reaches beyond campus in numerous ways. The Spacecraft Planetary Image Facility (SPIF) is a repository of spacecraft data, a facilitator of research, and a hub for PreK-12 education and public outreach activities. Ask an Astronomer has been answering questions from the curious since 1997. The Cornell Astronomical Society conducts viewing nights at the Fuertes Observatory and offers educational programing to the public.
