Guest Speakers


Expand Your Universe

The Universe is expanding and so is our scientific understanding of it. Macarthur Astronomical Society spreads this knowledge to our members and the public through the Macarthur Astronomy Forum at Western Sydney University.

We provide 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. 

The monthly Forums are held 7.30 pm – 9.30 pm on a Monday. Details can be found on our News & Events page. Go to our Forum Map page for details of how to get there.
