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 Solar System Astronomy Education

Wednesday, 2 May 2018 7:00 PM

In this session, we will take a look at the formation and evolution of the Solar System from a cold molecular cloud of dust and gas through to its ultimate end. We will discuss some common terminology and takes a peek at solar systems beyond our own.


At Last, Astronomy with Particles General Meeting

Wednesday, 2 May 2018 8:00 PM

Prior to the 20th Century, astronomy was only possible through the use of visible light. In the past century there has been a revolution in the use of “light” at other wavelengths – radio, x-rays, gamma-rays. The study of other “particles”, cosmic rays, as “messengers” began 50 years ago but progress was difficult and slow. However, in the past 5 years new particle “messengers” have become accessible in the form of gravitational waves and neutrinos. In the past year, there have also been breakthroughs in the study of cosmic rays. These new windows on the Universe are not yet well understood but astronomy is now very different to what it was a decade ago. The puzzles being currently addressed will be discussed in this talk.


Stellar Evolution - Part 1 Astronomy Education

Wednesday, 6 June 2018 7:00 PM

Looks at the Hertzsprung Russell (HR) Diagram which explains the relationship between luminosity, mass and temperature in stars during their various phases of evolution from a protostar and the main sequence through to red giants and white dwarfs.


T-Rex and the Volcanoes on the Moon General Meeting

Wednesday, 6 June 2018 8:00 PM

Scientists previously thought that the moon's volcanic activity died down a billion years ago. But data from NASA's Lunar Reconnaissance Orbiter, hints that lunar lava flowed much more recently, perhaps less than 100 million years ago. In this talk Joe Grida will explore the conditions that led to volcanism on the Moon in the past.
