International Dark Sky Week

International Dark Sky Week is a global celebration of the night.

From the darkness needed for a restful night’s sleep to the activities we enjoy beneath the stars, the night is filled with wonder and importance. Dark nights sustain critical wildlife ecosystems, strengthen the well-being of our communities, enable scientific discovery, and preserve shared cultural knowledge and traditions.

Join us this April as we “go dark” to explore the night and take action to protect dark skies worldwide.
