Welcome to the Astronomical Society of South Australia

The Astronomical Society of South Australia was founded in 1892 and is one of the largest organisations of its kind in Australia with over 600 members. We are the only representative body for amateur astronomy in the state of South Australia. Our mission is to observe, understand, share and to enjoy the wonders of the Universe. Most importantly, we promote Astronomy to the public to inspire and enrich the astronomer in everyone. Membership is open to anyone with an interest in Astronomy.

Our monthly meetings are free and include an Astronomy Education session and the main General Meeting which often features a guest speaker. The public and visitors are most welcome to attend.

What do the atmosphere of Venus, Apollo 15, Lalande’s catalogue of stars, Nova Persei, the largest world in the main asteroid belt, the final flight of the Space Shuttle and Foucault’s pendulum have in common? Stevo "Hard Quiz Champ" Raine will discuss these and other significant anniversaries in 2021 by taking you on a journey back in time to explain how they shaped Astronomy and us all.
