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.


Astronomy Education - February 2021

Wednesday, 3 February 2021 7:00 PM

This month we explore the inner planets of the Solar System from Mercury to Mars. These are the rocky planets which are similar to the Earth in composition. We also look at the new class of Dwarf planets which include Pluto, Ceres and Eris.


ASSA General Meeting - February 2021

Wednesday, 3 February 2021 8:00 PM

As we start a new year, and indeed a new decade, we always look forward to the astronomical highlights each year. Come along or tune in to our live broadcast to discover what to look out for in our southern skies in 2021. The Society has maintained a number of Special Interest Groups (SIG) over the years. The groups continue to evolve and we currently have four SIGs – Comets, Occultations, Meteors and Asteroids (COMA) lead by Joe Grida, Variable Stars lead by Robert Jenkins, Radio Astronomy lead by Blair Lade, and Astro-Imaging lead by Sarah Longcor. Each lead will briefly describe their SIG, talk about their activities and how they function, and show some examples of their work.


ASSA@Home Casual Friday

Friday, 12 February 2021 7:30 PM

This is a free-flowing live video session where members can discuss any aspect of our wonderful Astronomy hobby and the night sky. Topics can include how to find objects in the night sky, what equipment, software or books to buy, sharing something that has helped you in doing Astronomy, or general questions about ASSA and its facilities. The session is designed to be accessible and of interest to members at all levels.
