Light Pollution and Light Smog
The worldwide intensity of light pollution. Only dark colored regiones still have naturally dark nights. DIRN Observatory in Upper Austria is located at such a rare place.

Starting with the 21st century the use of artificial light in public areas in austria as well as worldwide is is rapidly growing. As a result of that fact a progressive brightening of the night sky brings manifold problematic impacts on man and environment. Exuberant artificial illumination "pollutes" the natural darkness by unnecessary and harmfull emissions and represents a special kind of environmental pollution.

Yet, for people living in rural environments, it is quite normal to look up to the sky and to see thousands of stars. Not a matter of course in our days, as cities and conurbations show, where the number of visible stars is reduced to few dozens. A most recently published high-carat report - The new world atlas of artificial night sky brightness proves, that about 60% of all Austrians never have seen the milky way! In other words, for two of three of our children a sky littered with stars is not more than hypothetic - unreachable as a country far away!

The reason is a new form of environmental pollution, a subject of dicussion since few years only but now developing a rapidly growing explosive nature: Light Pollution.
This term summarises the illumination of natural night landscapes by artificial sources of light. In Europe the ammount of emitted artificial light grows by ten to twenty percent - per year! The effects of this "light smog" on man, nature and environment are substantial - mostly even severe. This is about no less than the "loss of night" that is already completed in most densely populated areas and now threatens the rural regiones - often caused by a simple lack of information of the emitters of light.
