Artificial light at night has revolutionized the way we live and work outdoors, but it has come at a price. When used indiscriminately, outdoor lighting can disrupt wildlife, impact human health, waste money, and energy, contribute to climate change, and block our view of the universe.
The DarkSky International promotes win-win solutions that allow people to appreciate dark, star-filled skies while enjoying the benefits of responsible outdoor lighting.
The night sky, filled with stars, is celebrated and protected around the world as a shared heritage benefiting all living things.
