Join the Worldwide GLOBE at Night 2013 CampaignGLOBE at Night

What would it be like without stars at night? What would we lose? Starry night skies have given us poetry, art, music and the wonder to explore. A bright night sky affects energy consumption, health, and wildlife.


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.

People in 115 countries have contributed over 83,000 measurements each winter/spring over the last seven years, making GLOBE at Night one of the most successful light pollution awareness campaigns. There are four campaigns in 2013, and during GAM2013 you can participate in one or both that are listed below. Spend a few minutes to help scientists by measuring the brightness of your night sky - join the GLOBE at Night Campaign!
