Education & Public Engagement
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 to a website from a computer or smart phone. Light pollution threatens not only our “right to starlight”, but can affect energy consumption, wildlife and health. Over 211,000 measurements have been contributed from people in 180 countries during the year-round campaigns over the last 15 years, making Globe at Night the most successful light pollution awareness campaign to date!
Check out the web application data submission process. 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.
Our interactive map viewer allows you to explore the data that has been submitted by plotting it on a world map. Zoom in and see where the dark skies are near your hometown or compare how many data points have been submitted in you area over the past 15 years. The map viewer works on all devices, from smartphones to tablets, in addition to your computer.
