Welcome to the Astronomical Society of South Australia

The Astronomical Society of South Australia is the only representative body for amateur astronomy in the state of South Australia. Founded in 1892 and with around 600 members, it is the oldest and one of the largest organisations of its kind in Australia.


Our monthly meetings, which usually feature a guest speaker, are free, open to the public and visitors are most welcome to attend.


Stellar Evolution - Part 1 Astronomy Education

Wednesday, 6 June 2018 7:00 PM

Looks 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.


T-Rex and the Volcanoes on the Moon General Meeting

Wednesday, 6 June 2018 8:00 PM

Scientists previously thought that the moon's volcanic activity died down a billion years ago. But data from NASA's Lunar Reconnaissance Orbiter, hints that lunar lava flowed much more recently, perhaps less than 100 million years ago. In this talk Joe Grida will explore the conditions that led to volcanism on the Moon in the past.


The Light Fantastic General Meeting

Wednesday, 4 July 2018 8:00 PM

So much of what we know about the universe has travelled to us on a beam of light. We can’t travel to a star and pull one apart to see how it works. Instead, astronomers use light and the stories it tells to piece together our understanding of the universe.
