The Mornington Peninsula Astronomical Society (MPAS) is a volunteer-run, not-for-profit astronomical society at Mt Martha on the Mornington Peninsula. Founded in 1969, we foster the study of astronomy, space and general science — and share the wonder of the night sky with our members and the public.
What we do
- Hold monthly meetings where members exchange ideas and information, with talks, guest speakers and Sky for the Month.
- Run regular public and private stargazing nights to observe the Moon, planets and the season’s celestial highlights.
- Bring astronomy to schools and community groups through educational talks and observing nights, on the Peninsula and well beyond.
We’re a community of around 400 members — one of the larger volunteer astronomical societies in the Southern Hemisphere — from complete beginners to seasoned astrophotographers. You don’t need any experience or your own telescope, and visitors are always welcome.
