Reasons for light pollution

Even in remote regions light pollution disturbs. Here a view from the public observatory of the Naturwissenschaftlicher Verein Osnabrück in the direction of Osnabrück. The lights of Osnabrück are brighter than the Milky Way!

Satellite images taken at night show the sources of light pollution. This image has been processed by Winfried Kräling.

Reasons for the light pollution are:

"Skybeamer", as they are often used by discothèques

Bad or even wrong illumination of monuments

Bad street lighting
