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

Wednesday, 1 August 2018 7:00 PM

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.


It's Not Aliens! General Meeting

Wednesday, 1 August 2018 8:00 PM

This is not a talk about aliens (the clue is in the title!). Rather, it is a talk about strange astronomical observations that some people suggested might be 'aliens' but in fact are most likely to be unusual – but entirely natural – physical phenomena. This talk also tries to explain why 'aliens' is almost never the right explanation for weird and wonderful phenomena, but why it is nevertheless still very interesting to search for extraterrestrial life.


Galaxies Astronomy Education

Wednesday, 5 September 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.
