Welcome to the Astronomical Society of South Australia

The Astronomical Society of South Australia was founded in 1892 and is one of the largest organisations of its kind in Australia with over 750 members. Our mission is to observe, understand, share and to enjoy the wonders of the Universe. Most importantly, we promote Astronomy to the public to inspire and enrich the astronomer in everyone. Membership is open to anyone with an interest in Astronomy. You do not need to own a telescope. The Society is also the only representative body for amateur astronomers in the state of South Australia.

Our monthly General Meeting is held at The Braggs Lecture Theatre at the University of Adelaide at 8pm on the first Wednesday of each month, excluding January.

The General Meeting is preceeded at 7pm by an Astronomy Education session for those looking for an introduction to Astronomy and our Universe.

The main General Meeting features a presentation from a professional astronomer or guest speaker with a wide range of topics aligned with Astronomy, Space, Science and Physics.

These sessions are open to the public and free for all to attend. No ticket required.

Betty Louise Turtle (nee Webster) was born 20th May 1941 and raised in Adelaide, South Australia. After gaining her Ph.D. Louise worked at the Royal Greenwich Observatory at Herstmonceux, Sussex, UK. It was there in 1971 that she and Paul Murdin were the first astronomers to discover a black hole. After a stint in South Africa Louise returned to Australia, initially working at Siding Spring observatory and then moving in 1978 to the University of New South Wales as a tutor in the School of Physics. Louise published widely and her papers were often cited by other astronomers. In 1989 she was appointed head of the Department of Astrophysics and Optics. Louise died in 1990 and is buried in Adelaide. Despite these significant achievements Louise is not well known.
