Guest Speakers

Macarthur Astronomy Forum

Expand Your Universe

We are passionate about learning more about the Cosmos and freely sharing this knowledge with the community. 

Public Outreach Programme

The Forum meets at 7.30 pm on the third monday of each month (January to November) and the second monday of December. Public admission by gold coin donation.

With presentations that non-scientists can understand, we provide a platform for Australian and international astronomers to disseminate details of their research and discoveries about the Universe.

We also allocate spots for advanced amateur astronomers to speak on the basics of amateur astronomy and the December Forum is devoted to presentations from local school students.

Please also see the Macarthur Astronomy Forum entry in Wikipedia.


Held at



The venue for the meetings of Macarthur Astronomical Society has been provided courtesy of Western Sydney University since 1996. 

MAS acknowledges the cooperation of WSU and Campbelltown Rotary Observatory in promoting the science of astronomy within the Macarthur community.
