Twinkle, Twinkle Little Star! – New App Measures Sky Brightness

Researchers from the German “Loss of the Night” project have developed an app for Android smart phones, which counts the number of visible stars in the sky. The data from the app will be used by scientists to understand light pollution on a world wide scale.

n natural areas you can see several thousand stars with the naked eye” says Dr. Christopher Kyba, physicist at the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) and Freie Universität. “In Berlin, we can still see several hundred, but the situation in most large cities and world capitals is far worse.”
The smartphone app will evaluate sky brightness, also known as skyglow, on a worldwide scale. It will be an extension to the “GLOBE at Night” citizen science project, which has been running since 2006. This data can be used to map the distribution and changes in sky brightness, and will eventually allow scientists to investigate correlations with health, biodiversity, energy waste and other factors.

“Life evolved periodic changes of bright days and dark nights” says Dr. Annette Krop-Benesch of the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB). “The introduction of artificial light into the atmosphere is changing ecosystems worldwide, and might even have an impact on our health. Unfortunately, we have very little information about light levels in different habitats at night.”
