Astronomy

The American Astronomical Society is the major organization of professional astronomers in North America. The AAS was established in 1899 and based in Washington, DC. Our membership of about 7,700 individuals also includes physicists, mathematicians, geologists, engineers, and others whose research and educational interests lie within the broad spectrum of subjects now comprising the astronomical sciences.

Based in San Francisco, CA. Through its materials, resources, and programs, the ASP promotes public science interest, engagement, and literacy through the awe and wonder of astronomy and related fields. ASP envisions a world where people of all ages and backgrounds engage in astronomy and share their passion for astronomy with others. ASP believes astronomy is a fundamentally democratic science, with the cosmos equally accessible to all people regardless of age, gender, background, ethnicity, economic status, or abilities.

The National Aeronautics and Space Administration (NASA) is an independent agency of the U.S. Federal Government responsible for the civilian space program, as well as aeronautics and space research.
