Use your phone to map out light con­tam­i­na­tion

Science Illustrated - - SPACE -

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.

GET STARTED: Down­load the Loss of the Night app.
