Twenty-nine scientists working at or affiliated with NASA have been named Fellows of the American Astronomical Society (AAS), the major organization of professional astronomers in North America. 

The AAS Fellows program was established in 2019 to honor members for their contributions toward the AAS mission of enhancing and sharing humanity’s scientific understanding of the universe. Being named a Fellow honors members for extraordinary achievement and service. AAS Fellows will be recognized for original research and publication, innovative contributions to astronomical techniques or instrumentation, significant contributions to education and public outreach, and noteworthy service to astronomy and to the Society itself. 

The AAS Board of Trustees has designated an initial group of more than 200 Legacy Fellows. These include past recipients of certain awards from the AAS or its topical Divisions, distinguished AAS elected leaders and volunteer committee members, and previously unrecognized individuals with long histories of outstanding research, teaching, mentoring, and service.
