O Radiant Dark! O Starry Night!

Starry night skies are components of the special places the National Park Service protects. Our national parks hold some of the last remaining harbors of darkness and provide opportunities for the public to experience this critical resource. Animals rely on natural cycles of light and dark for navigation, protection, mating and predation. Natural lightscapes are integral to many cultures. Light pollution disrupts these relationships. NPS helps preserve night viewsheds for future generations.
