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 750 members. 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. You do not need to own a telescope. The Society is also the only representative body for amateur astronomers in the state of South Australia.

Our monthly General Meeting is held at The Braggs Lecture Theatre at the University of Adelaide at 8pm on the first Wednesday of each month, excluding January.

The General Meeting is preceeded at 7pm by an Astronomy Education session for those looking for an introduction to Astronomy and our Universe.

The main General Meeting features a presentation from a professional astronomer or guest speaker with a wide range of topics aligned with Astronomy, Space, Science and Physics.

These sessions are open to the public and free for all to attend. No ticket required.


Astronomy Education: June 2025

In this session we will take a close look at the Hertzsprung Russell (HR) Diagram which explains the relationship between luminosity, mass and temperature in stars during their various phases of evolution from a protostar and the main sequence through to red giants and white dwarfs.

Astronomy today is going through a golden age with amazing new facilities exploring the Universe. The James Webb Space Telescope is re-writing the textbook on baby galaxies, while gravitational wave observatories are detecting vibrations in space caused by colliding black holes. But there’s much more to come, with gigantic new telescopes in the pipeline that truly boggle the imagination. What are these awe-inspiring instruments, and what will they reveal about the Universe’s deepest mysteries? And will Australian astronomers play a part? Join Fred Watson for this entertaining and fully illustrated look into the future of astronomy.
