Use the RAO's activity guides and worksheets to learn about the importance of dark skies, observe the moon, and measure the brightness of the sky.
Learning Opportunities with RAO Partners:
Learn more about the Ann and Sandy Cross Conservation Area, a nocturnal preserve near the RAO. It is dedicated to protecting habitat and providing space for native species of wildlife. Learn about the birds and animals that are active in the night and how the ASCCA conserves the land and night sky.
Learn how to reduce the risks faced by migratory birds. The Calgary Migratory Bird Response Team surveys birds and bats in Calgary to learn how they are adapting to the challenge of light pollution. Learn more about their citizen science project and how you can help.

What is light pollution?
Light pollution is excess artificial light that has a negative affect on humans, birds, animals, and plant life. Protecting the wilderness of the night sky is as as important as protecting the rest of our environment.

Measure the darkness of the sky near you
The Rothney Astrophysical Observatory is calling on citizen scientists to make brightness observations of the night sky over their homes.
