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.

Multi-Messenger Astronomy. Fashionable, but is it real? General Meeting

Wednesday, 5 October 2016 8:00 PM

The expression "multi-messenger astronomy" is quite a new term, which is becoming commonly used in astronomy, perhaps most often in funding applications. It seems to refer to the combined use of many astronomical techniques, and instruments at different wavelengths or with different 'messengers', to get an understanding of the objects which we see in the sky. Some of us would say that it what we have been doing for decades but it is a new idea for people in some areas of astronomy. Emeritus Prof. Roger Clay (University of Adelaide) will try to explain how the use of information using multiple wavelengths and messengers can allow us to get to a real understanding of how astronomical objects really work.
