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.


Variable Stars Astronomy Education

As a conclusion to the series on Stellar Evolution, we will take a look at Variable Stars. This will include exploring such objects as cepheid variables, long period variables like Mira, eclipsing binaries and cataclysmic variables like Eta Carina.


Astronomical Anniversaries 2018 General Meeting

Wednesday, 3 October 2018 8:00 PM

From the detection of stellar parallax by Bessel, to the questionable patenting of the newly invented telescope, from Mirzam varying slightly to the whopping massive blast over Tunguska, from a Phoenix landing on a Martian polar cap to Apollo 8’s capture of Earthrise; 2018 boasts some remarkable astronomical anniversaries. Come along and Steven Raine will discuss some of these significant places, people and history commemorating their decadal anniversaries this year showing how we've progressed and learnt through the ages and through some remarkable work by some fascinating people and some of the sights we've seen over centuries.


Galaxies Astronomy Education

Wednesday, 7 November 2018 7:00 PM

After exploring our own galaxy, The Milky Way, we will look at the Local Group of Galaxies and beyond. The various types of galaxies will be discussed and how they are classified using Hubble’s Tuning Fork diagram.


Solar System Planetary Interiors General Meeting

Wednesday, 7 November 2018 8:00 PM

In this talk Prof Caprarelli will discuss the planets of our solar system using a comparative planetology approach. Through the exploration of key concepts of planetary geophysics and cosmochemistry, she will present an analysis of the differences among the planets of our solar system, with Earth as the planet of reference.
