About Globe at Night

The Globe at Night program is an international citizen-science campaign to raise public awareness of the impact of light pollution by inviting citizen-scientists to measure their night sky brightness and submit their observations from a computer or smart phone. Light pollution threatens not only our “right to starlight”, but can affect energy consumption, wildlife and health. More than 200,000 measurements have been contributed from people in 180 countries over the last 14 years, making Globe at Night the most successful light pollution awareness campaign to date!

Explore the last 16 years of data in our interactive data map, where you can see how your area is doing by inputting your city’s name in the Location Box at the top of the map. Add a radius and tap or click “Search” to see the results. The Globe at Night website is easy to use, comprehensive and holds an abundance of background information. The database is usable for comparisons with a variety of other databases, like how light pollution affects the foraging habits of bats.
