The Great World Wide Star Count is an international event that encourages learning in astronomy by inviting everyone to go outside, look skywards after dark, count the stars they see in certain constellations, and report what they see online. These observations are used to determine the amount and spread of light pollution worldwide. Participating in the event is fun and easy! You can join thousands of other students, families and citizen scientists from around the world counting stars. Don't miss out!
