About the talk:

The term ’light pollution’ characterises the influence of artificial light on the natural dark sky. It is a worldwide issue and can be dated back at least to the beginning of the 20th century, caused by light coming from the ground and comprises phenomena like light trespass, light scattering in the atmosphere and huge 'domes' of light around cities. The ever-worsening phenomenon impairs not only the visibility of objects on the night sky, but also inhibits the dormancy of plants, disrupts nocturnal activities of animals and provides negative effects on human health. In the last decade, light pollution research became of major importance and grew to be highly multi-disciplinary. The talk will elucidate the topic from several perspectives, including from an astronomical, ecological and environmental point of view, its global status, legal situation, results of current research activities and potential actions against further increases.
