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.

Planetary Moons & Asteroids Astronomy Education

Dr Robert Dahni (retired BoM meteorologist) will take you on a journey into the past, present and future of the Cloud Free Night service - a non-profit online weather forecast service for Australian astronomers, highlighting not only the meteorological, astronomical and technical aspects, but the personal contributions from the Australian astronomy community.

Collapsars Astronomy Education

Wednesday, 3 May 2017 7:00 PM

Collapsars are literally Collapsed Stars which have gravitationally contracted at the end of their long lives into incredibly dense objects. In this session, we explore White Dwarfs, Neutron Stars and Black Holes.

Astronomical Sketching General Meeting

Wednesday, 3 May 2017 8:00 PM

Astronomical sketching at the telescope has long been relegated to a quaint pre-photgraphic past. Why would anyone bother to sketch what is seen with a telescope these days? A small but growing cadre of observers are however returning to this old art and are reclaiming a lost satisfaction in carefully peering through the eyepiece and with pencils, smudge stubs and brushes translating what they see on to cartridge paper. Martin Lewicki will show how.
