It has been revealed in a new study that nearly 90% of visitors to Acadia National Park in Maine recognized that viewing its dark night skies, which are free from pollution of artificial light, is something that is needed to pay attention to. The study has been conducted by Robert Manning from the University of Vermont.

The study has been published in Park Science. The Acadia National Park is also called its annual Night Skies Festivals. It has been written on its website that its work is to come up with a community celebration in order to promote the enjoyment and protection of Acadia's stellar night sky through science, education and arts. It will occur on September 10th and 14th.

The study says that dark night skies have vanished as a result of pollution from artificial light that leads to production of a "sky glow", which reduces the brightness of the stars and also human eyes find it difficult to completely adapt to the night darkness. The lights of the urban areas have an influence on the quality of nighttime; it happens even when they are at a distance of as much as 250 miles from national parks.

According to Manning, 99% of the skies are polluted by artificial light and those who visit the park are the only ones who can completely see night's darkness.

According to Manning, "Though light pollution may have already had irreversible biological and ecological impacts, it can be controlled and even reduced. The national parks, with their emphasis on protection of natural and cultural resources are a good place to advance this cause".
