We have teamed up with Siding Spring Observatory and Dubbo School of Distant Education to help protect the dark night sky from light pollution.

What is light pollution?

Light pollution is the brightening of the night sky from artificial light.


Artificial light can be lights from our homes, street lights, lights from schools and sporting parks.


Too much light pollution can:

  • affect the environment
  • disrupt the normal breeding and migration patterns of nocturnal animals
  • have negative health impacts on human beings
  • restrict observatories ability to see and research the night sky.

How can I help protect the night sky?

  • read the Dark Sky Planning Guideline for practical advice on how to minimise light pollution in your home
  • talk to your teachers about introducing the dark sky education unit in your school
  • watch our video series to hear leading experts talk about the impacts of light pollution on the environment and human health.
