International Dark Sky Week is a worldwide celebration of the dark and natural night. 

For many, the dark night is often misunderstood, unfamiliar, and frightening. But the natural night is filled with wonder and awe, and is critical to the health and wellbeing of our planet. 

Dark Sky invites you to join this initiative where you can discover the night, learn about the harmful effects of night pollution and what we can do to embrace the dark and save the night.
