There are thousands of stars in the night sky that are visible to the naked eye — or they should be. In major towns and cities around the world you're lucky to see more than a dozen stars on a clear night, and the reason is light pollution.

Light pollution it doesn't just cause problems for star-gazers, it affects energy consumption, health and wildlife, too. But you can make a difference! Join the Globe at Night citizen-scientist campaign and in just a few short minutes you can help us measure the brightness of the night sky around the world.
