Dark Skies Initiative

The Fairfax County Board of Supervisors proclaimed April 22-30, 2022, as Dark Sky Week in Fairfax County. Dark skies are the historic and natural state of nature. Over time humans have increased the amount of light shining into the sky all night long. This disruption of excessive light has robbed us of our stars and endangered the nature around us. We can have dark skies again if we can learn to control light pollution with responsible outdoor lighting practices.
