The American Astronomical Society (AAS) serves as the primary professional organization for astronomers and related scientists in the United States. This overview outlines its history, structure, key functions, major contributions, and the broad array of activities that support the astronomical community, from early career development to policy advocacy.
1. History & Purpose
Founded in the early 20th century, the AAS grew from a modest assembly of observatory astronomers into a major national and international network. The society’s mission has consistently focused on: research promotion, education, community service, and policy advocacy. Over the past century, the AAS has fostered the construction of large observatories, facilitated the launch of space telescopes, and helped secure funding for key astronomical initiatives.
