Dark Sky Parks in the United States

There are 28 dark sky parks, preserves, and communities across the United States.

Light pollution is a continuous reality for many cities around the world. The use of artificial lighting during the night has led to disruptions in the nocturnal environment. These disruptions cause problems for plants, animals, and even humans by interfering with the natural night-day cycle. With rising awareness on the importance of a dark sky in the night, astronauts and national organizations have created areas away from interference by artificial light called dark sky parks. These areas exist in categories such as communities, reserves, preserves, and sanctuaries. Dark sky parks help astronomers in studying the night skies and for stargazers who wish to enjoy the night skies. There are 28 dark sky parks in the US located in various states. The International Dark-Sky Association designates the parks.
