Light pollution is the alteration of natural light levels in the outdoor environment due to manmade light sources. Reported adverse effects of light pollution involve the animal kingdom, the vegetable kingdom and mankind. 

One of the most noticeable effects of light pollution is the increase in night sky brightness. The light wasted upward by the night-time outdoor lighting, in facts, lights up the atmospheric particles and molecules producing a luminous background which obstructs the vision of the night sky. This causes the loss of perception of the Universe where we live.

This Web Site has the  purposes to give you information on the problem of light pollution in Italy and on its possible solutions.

The Proceedings of the Convention "Light Pollution and the Protection of the Night Environment - Venice: let's save the night"  are collected in a book of 356 pages, edited by  Pierantonio Cinzano and published by the Light Pollution Science and Technology Institute (ISTIL) with the support of UNESCO-ROSTE. The book reviews the many aspects of light pollution with a simple language through contributions of authors of international relevance:  the importance of stargazing to man throughout the centuries, the situation of the night sky in Europe and Italy, ecological consequences of artificial night lighting, teaching light pollution at school, technical measures for an effective limitation of its effects, controlling light pollution in Eastern Europe and much more. Available on-line.

Measuring and modelling light pollution is the title of a  book of 280 pages in English language, edited by Pierantonio Cinzano and published in 2000 by the Italian Astronomical Society (tel.055 2752270). It collect 25 research papers from the main people of the field. Available on-line. Also available on ADS.
