International Dark Sky Week


Mud Lake

International Dark Sky Week, April 5-12, is set aside to discover more about the constellations, planets, and celestial objects above our heads, and the dark skies that make these possible to see. Light pollution often obliterates our ability to see the skies, and causes harm in various ways to both humans and wildlife.

Boulder County Parks & Open Space is teaming up with the Longmont Astronomical Society to bring you daily emails April 5-9 with fun facts about dark skies, sky views, and ways you can help combat light pollution.

Sign up to receive a daily email during International Dark Sky Week and learn how to be a dark sky defender!
