Use your phone to map out light contamination
Artificial light makes it hard to see stars in many places. The light is not only a problem for stargazers, rather also for many animals. The “Loss of the Night” research project maps out and compares light contamination with the behaviour of fish, birds, and bats. You only need to download an app and aim your phone at the night sky to make the app count the number of visible stars in the spot where you are and send the information to scientists along with the GPS coordinates.
