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 Moon Astronomy Education

T-Rex and the Volcanoes on the Moon General Meeting

Wednesday, 7 February 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 we’ll explore the conditions that led to volcanism on the Moon in the past.
