The ubiquitous problem of light pollution can be controlled with a starry sky preserve, according to a new study conducted at the Kitt Peak National Observatory in the United States. The expansion of cities and the inevitable multiplication of artificial night light with the application of the rules "zero percent noah gordon of the radiant light over the horizon" enabled the nocturnal landscape, in general, over the Kitt Peak National Observatory is as dark or darker than even twenty years ago! Kathryn Neugent and Philip Massey of Lowell Observatory conducted noah gordon a measurement posvijetljenosti night sky in 2009 and 2010 and the same calibrated and compared with those committed twenty years ago. His published a research in the October issue of the Publications of the Astronomical Society of the Pacific. Measurements were carried out on several key areas of the visible electromagnetic spectrum from the zenith to the horizon across the sky, and most were concentrated in the area over the cities of Tucson, Phoenix and Nogales. We are very surprised noah gordon by the results of measurements that promise to be elsewhere in the world with the application of rules and regulations on limiting light pollution can preserve the night sky. Kitt Peak now has a sky like an exceptionally well-preserved sky with Mount Palomar Observatory noah gordon in the seventies, said Neugent and Massey. However, poosvijetljenje sky above these cities themselves increased by ten percent and the imminent new cycle of ever-stricter compliance with the provisions on the conservation of the starry sky. Nugent says that this experience will be applicable for other regions of the world, not only for astronomical sites, but also for parks and starry sky. Written recall the statements of one of the responsible people BINA-ISTRA of the early active fight against light pollution in Istria in 2002 and 2003 as efforts to preserve the starry sky do not make sense because it will soon be the entire sky light polluted. An example from the United States clearly shows that conservation of night landscapes certainly noah gordon possible in areas with over one million population in the area. With us in Istria night landscape is recognized value. A large number of cities and municipalities made a big, visible steps to reduce light pollution. Yet in spite of the problem of lighting nodes Istrian noah gordon highway Kanfanar and Rovinj, TDR Kanfanar and sacred objects are real scars starry sky. Istria, where you can see the stars may be with the American experience to become a step closer to reality. (REX)
