Expand Your Universe

The Universe is expanding and so is our scientific knowledge of it. Our aim is to spread this knowledge to our members and the public.

Macarthur Astronomical Society organises the Macarthur Astronomy Forum as a platform for notable Australian and international astronomers to share their discoveries about the Universe with the Macarthur community – in a non-technical format which is understandable to non-scientists. 

We hope to have as many in-person speakers as possible at our Forums, although occasionally a speaker may choose to Zoom their talks into the meeting.

The Forums are held 7.30 pm – 9.30 pm on a Monday of each month.

Details of our next Forum can be found on our News & Events page. Go to our Forum Map page for details of how to get there.
