'''Light pollution''' is a man-made phenomenon whereby a detailed view of the night sky is obscured by excessive or poorly-designed artificial lighting, especially in or around cities and towns. This is a significant concern for amateur and professional [[astronomers]], since the vast majority of [[stars]] and astronomical features which would otherwise be visible from the earth's surface are hidden from view, or visible at a decreased resolution, within many miles of a developed population centre. | '''Light pollution''' is a man-made phenomenon whereby a detailed view of the night sky is obscured by excessive or poorly-designed artificial lighting, especially in or around cities and towns.
