The Smithsonian Astrophysical Observatory (SAO), founded in 1890, is a research center of the Smithsonian Institution with the mission to advance our knowledge and understanding of the universe through research and education in astronomy and astrophysics. Affiliated with the Harvard College Observatory, SAO created the world’s first satellite-tracking network, establishing the organization as a pioneer in space science research. In 1973, the Smithsonian and Harvard created the joint Center for Astrophysics | Harvard & Smithsonian.

Key areas of research include exoplanets, the sun and solar weather, asteroids and comets, and "The Extreme Universe" that includes the study of black holes, pulsars, supernovae, white dwarfs, neutron stars, and magnetars.
