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.

Galaxies Astronomy Education

Wednesday, 2 November 2016 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.

Liquid Water on Mars and its Implications for Life General Meeting

Wednesday, 2 November 2016 8:00 PM

Given our current state of knowledge of life on Earth, three pre-requisites are necessary for an environment to be ‘habitable’ and therefore capable of supporting terrestrial-like life: energy, biogenic elements, and liquid water. Using evidence from the Phoenix Lander and the Mars Science Laboratory, Dr Eriita Jones from the University of South Australia will discuss the occurrence of these three factors and habitable conditions in the shallow Martian regolith.

Cosmology Astronomy Education

Wednesday, 7 December 2016 7:00 PM

Find out how it all began. We will look at The Big Bang. How it evolved into the Universe we see today and look at possible fates of the Universe. We will also discuss red shifts and those mysterious entities, dark matter and dark energy.
