A protected Night Sky over Flagstaff, Arizona

When the great earth, abandoning day, rolls up the deeps of the heavens and the universe, a new door opens for the human spirit, and there are few so clownish that some awareness of the mystery of being does not touch them as they gaze. 

— Henry Beston, The Outermost House (1928)

Setting the Gold Standard for night sky protection

A dark, star-filled night sky is often thought of as important for astronomy or research. Though this is true, the grandeur of the night sky is much deeper and broader, and accessible to anyone. We find the beauty and meaning of natural night is best expressed by poets and writers, such as Henry Beston.

Although astronomers and astronomy are important (some of our best friends are astronomers), protecting the night sky just for astronomers would be like protecting Grand Canyon just for geologists. Yet no one ever seems to think so narrowly about the Canyon; it is our hope that after looking through our website you may think more broadly about the night sky.

As the international dark sky movement began in Flagstaff in 1958, our community has always been keenly aware of the special value of the night sky. The Flagstaff Dark Skies Coalition and the greater community of Flagstaff are proud to remain world leaders in practical and successful dark sky protection.

FDSC is a chapter of the International Dark-Sky Association.
