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.

The Night Sky Astronomy Education

In this session, we will look at the Night Sky and discuss the mechanics of the celestial sphere. Learn how to find your way around the sky and become familiar with common terms. We will also look at some of the brighter stars which are high in the sky in autumn and how to find them.

Radio Astronomy for the Amateur Scientist General Meeting

Wednesday, 7 March 2018 8:00 PM

The areas covered in this fully illustrated talk will include the birth of Radio Astronomy and how radio emissions work. Furthermore, it will explore the science being done at the Leon Mow Radio Observatory in Victoria and explain some simple radio astronomy experiments that can be done.

The Sun Astronomy Education

Wednesday, 4 April 2018 7:00 PM

This month we take a close look at our local star, The Sun. How did it form? What keeps it shining for billions of years and what will be its ulmate fate in far distant future? These and other aspects of the Sun will be discussed.

Misconceptions About the Big Bang General Meeting

Wednesday, 4 April 2018 8:00 PM

The importance of the big bang model is only exceeded by how misunderstood it is. If space is expanding, what is it expanding into? What happened before the big bang? What caused the big bang? Are distant galaxies receding faster than the speed of light? I will describe the most common misconceptions about the big bang, and describe what we know and don’t know about the hot big bang origin of our universe.
