The Australasian Dark Sky Alliance

As cities get bigger, they produce more and more light. Because of this, light has become the fastest-growing pollutant in the world, increasing by 2% each year. Only 20% of the world’s population can see the whole night sky, and as urban areas grow this percentage will shrink. But rising right pollution isn’t just a problem that affects astronomers, but a wide range of various industries and groups – as well as the general public. That’s why a group of volunteers from different backgrounds have come together to form the Australasian Dark Sky Alliance to help conserve the night sky.


To tell us more about it, we were joined by ADSA board member and Associate Professor of Astronomy at Macquarie University, Richard McDermid.
