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 650 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 presentation from a professional astronomer. Visitors are most welcome to attend.

ASSA@Home | Roads Less Travelled

Friday, 17 December 2021 7:30 PM

The summer night sky is full of dazzling deep-sky targets to lure you. But there are equally exciting objects in corners of the southern sky where most amateurs don't travel. Join Paul Martinaitis and Joe Grida as they guide you through the back roads to vistas you never knew existed.

Public Viewing Nights

Experience the wonders of the night sky through a telescope! We plan to re-commence regular in-person viewing nights in 2022 once new community-wide COVID safety measures become the norm.

In the meantime, advanced real-time imaging telescopes will be used to display celestial objects at public in-person and online events.

We have not yet added any upcoming events - please check back soon.
