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 700 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.

Wonders of the Cosmos

Wednesday, 7 October 2020 7:00 PM

Astronomy is a natural science that studies celestial objects and phenomena. In this episode we condense the entire field of Astronomy into one lecture. This takes us on a journey from the searing heart of the Sun through the solar system and into deep space to explore nebulae, clusters, galaxies and more.

Probing Alien Worlds from Down Under

Wednesday, 7 October 2020 8:00 PM

As a naturally curious and adventurous species, humans have scaled mountains, crossed deserts and oceans, trying to answer a very fundamental question: Are we alone? Now that we’ve explored the niches of our own planet, it’s now up to astronomers like myself to cross the vast cosmic ocean to find life elsewhere within our Milky Way galaxy. But how do we find planets dancing around other stars? What makes another world habitable for life as we know it? And how are doing all of this within our own backyard? Well, you'll just have to come to this talk to find out!
