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.

Stellar Evolution - Part 2 Astronomy Education

Wednesday, 3 August 2016 7:00 PM

NOTE NEW SESSION DATE! This session continues the discussion of Stellar Evolution with a complete overview of the lives of stars of various masses from birth within gaseous nebulae to their ultimate demise as a white dwarf or supernova explosion.

A Look Back in Time General Meeting

Wednesday, 3 August 2016 8:00 PM

There are many deep sky objects that are beyond naked eye visibility. Using long exposure times we are able to reveal many of these deep sky wonders. In this talk, Paul Haese will reveal these cosmic vistas, and take you on a tour of the many images he has taken of galaxies, globular clusters and nebulae.

Variable Stars Astronomy Education

Wednesday, 7 September 2016 7:00 PM

As a conclusion to the series on Stellar Evolution, we will take a look at Variable Stars. This will include exploring such objects as cepheid variables, long period variables like Mira, eclipsing binaries and cataclysmic variables like Eta Carina.

Australia and the Giant Magellan Telescope General Meeting

Wednesday, 7 September 2016 8:00 PM

Australia is playing a major role in the Giant Magellan Telescope (GMT) project, building two of the first-generation GMT instruments and key components of the adaptive optics system that will give GMT the sharpest resolution of any telescope - nearly 10 times better than Hubble and 3 times better than JWST. Combined with the largest light-collecting area of any telescope, this will enable GMT to do some extraordinary science. Amongst other things, GMT will be able to detect the very first stars to form in the universe, trace the assembly of galaxies over the whole of cosmic history, and analyse the atmospheres of planets orbiting nearby stars.
