American professional organization of astronomers

The American Astronomical Society (AAS) is an American professional society of astronomers and other interested individuals. Its primary objective is to promote the advancement of astronomy and closely related branches of science, while the secondary purpose includes enhancing astronomy education and providing a political voice for its members through lobbying and grassroots activities. Its current mission is to enhance and share humanity's scientific understanding of the universe as a diverse and inclusive astronomical community.2 It was founded by George Ellery Hale.1 Its revenue was $19.2 million in 2023.1 Wikipedia text CC BY-SA 4.0

The story

Founded by George Ellery Hale in 1899.1

The society was founded in 1899 through the efforts of George Ellery Hale. The constitution of the group was written by Hale, George Comstock, Edward Morley, Simon Newcomb and Edward Charles Pickering. These men, plus four others, were the first Executive Council of the society; Newcomb was the first president. The initial membership was 114. The AAS name of the society was not finally decided until 1915, previously it was the "Astronomical and Astrophysical Society of America". One proposed name that preceded this interim name was "American Astrophysical Society".

The AAS today has over 8,000 members and six divisions – the Division for Planetary Sciences (1968), the Division on Dynamical Astronomy (1969), the High Energy Astrophysics Division (1969), the Solar Physics Division (1969), the Historical Astronomy Division (1980) and the Laboratory Astrophysics Division (2012). The membership includes physicists, mathematicians, geologists, engineers and others whose research interests lie within the broad spectrum of subjects now comprising contemporary astronomy. The annual meeting of the AAS is held in the spring and constitutes the largest gathering of astronomers, numbering over 3,000 in 2023.

In 2019 three AAS members were selected into the tenth anniversary class of TED Fellows.

The AAS established the AAS Fellows program in 2019 to "confer recognition upon AAS members for achievement and extraordinary service to the field of astronomy and the American Astronomical Society." The inaugural class was designated by the AAS Board of Trustees and includes an initial group of 232 Legacy Fellows.

In January 2025, AAS published a statement calling on nations to ban advertising from space that can be seen from the ground amid growing concern around the launch obtrusive space advertising payloads.

Products and brands

Because the field of astronomy is diverse, several divisions have been formed each of which promotes and enables a different branch of astronomy or astronomy-related science as well as working within the overall charter of the AAS. Many of the divisions hold separate meetings in addition to meeting with the main group. The divisions of the AAS, together with their main research interests, are:

The Division for Planetary Sciences (DPS) supports planetology and exploration of the Solar System.

The Division on Dynamical Astronomy (DDA) supports research on the dynamics (orbits, evolution, and history) of astronomical systems from the Solar System to superclusters of galaxies on cosmological scales.

The High Energy Astrophysics Division (HEAD) supports knowledge about high energy events, particles, quanta, relativistic gravitational fields, and related phenomena in the astrophysical universe.

The Historical Astronomy Division (HAD) supports topics relevant to the history of astronomy as a field, and research using historical astronomical records to solve current problems in astronomy.

The Solar Physics Division (SPD) supports solar physics (astrophysical research on the Sun), and its interactions with the Solar System and Earth.

In 2012, a new division was formed: the Laboratory Astrophysics Division (LAD) to advance humanity's understanding of the Universe through the promotion of fundamental theoretical and experimental research into the underlying processes that drive the Universe.
