Abstract Title: -Where are the stars? - A citizen science project on light pollution
Abstract: A large fraction of Earth population lives in urban areas. Scientific studies have shown that scattered artificial light --light pollution--have unexpected and worrying negative effects on the biology of many organisms, ecosystems, and on human health, in ways that most people cannot imaging. However, we use street lamps, illuminated signs, car-light, etc., to improve safety and make cities more attractive at night. In the Star-Spotting Experiment, hundreds of thousands of inhabitants in several European countries are being invited to contribute to scientific research about light pollution. The experiment builds on the fact that the more light there is, the fewer stars you see. We encourage people to count stars where they live, using a simple method, and report via an App. We present results on peoples' awareness of the night sky, how this method compares to other measures of light pollution, and possible consequences for ecology and urban planning.
