The American Astronomical Society is a professional organization made up of the top astronomers in North America. Established in 1899, their mission is to "enhance and share humanity's scientific understanding of the universe".

Twice a year, AAS meets to discuss the latest in science, network with other members, and present research from within their respective fields. In the past, these meetings were hosted in person. However, 2020's COVID-19 pandemic forced the team to shift the event online. In June 2020, the first AAS virtual meeting was hosted with vFairs.
