Globe at Night is an international citizen-science campaign to raise public awareness of the impact of light pollution by inviting citizen-scientists to measure & submit their night sky brightness observations. It's easy to get involved - all you need is computer or smart phone & follow these 5 Simple Steps!
So far in 2017 citizen scientists from around the world have contributed10,610 data points, getting us more than half way to our goal of 20,000! Help us make it a record setting year!
