An Overview of Australian Night Skies

Looking at Australia from space at night, our continent is still relatively dark, so why is there a need to protect the nighttime environment? For years astronomers have been aware of the effect of light in our night skies, ruining the ability to clearly see the night time wonders. Scientists around the world are increasingly becoming aware of the effect of artificial light on our finances, environment and even, human health.

Join Marnie Ogg the founder of the Australasian Dark Sky Alliance, as she discusses ways we can all help to reduce light pollution.

Marnie Ogg

Marnie's drive and enthusiasm have been borne for a stellar career. She started at the grassroots of the travel industry building her own successful travel company, taking people around the world to visit places of scientific interest. She managed Sydney Observatory before devoting her time to one of her passions: preserving the night sky. In July 2016 the Warrumbungle National Park was designated a Dark Sky Park - the first in Australia. As Founding Director of the Australasian Dark Sky Alliance, she now spends her time educating every one of this globally expanding movement to reduce light pollution.


MAS Partners With Return and Earn

ER 1

We are proud to announce that MAS has become a Donation Partner with Return & Earn in the Macarthur area for the period Monday 26th August until Sunday 24th November 2019.

Return and Earn is a NSW litter reduction initiative, which was introduced in 2017.

Littering impacts all of us. It spoils our environment, costs millions of dollars to clean up, and is associated with anti-social behaviour. 


We have been assigned thirteen local Reverse Vending Machines (RVMs) for this period, see Local RVM List.

When you take eligible containers to an RVM for recycling, simply select "Donations - Local Charity - Macarthur Astronomical Society" - and MAS will earn the donated refunds of 10 cents per container.

MAS members, family and the public are encouraged to participate in this opportunity to further our activities and public outreach programs.

Return and Earn is helping to meet the goal of reducing the volume of litter in NSW by 40 per cent by 2020. See here for How it WorksSee here for your local council Return & Earn pages:   Campbelltown,   Camden,   Wollondilly,   Liverpool.
