Want to help monitor light pollution in your town? Globe at Night collects observations of the night sky using the constellations or an app on your phone every month when the Moon is not in the evening sky. It’s time again for another campaign, July 16 – 25. Enjoy those balmy night skies (if you’re in the Northern Hemisphere).

For lots more on Globe at Night’s 2014 campaign and how to use the site and apps, see our recent Learning Space episode, “Come to the Dark Side.”
