Join us for one of the premier night sky events on the eastern seaboard. The 10th Annual Acadia Night Sky Festival is set for September 5-9, 2018, and will once again be packed with a full schedule of events. With workshops, internationally recognized speakers and hands-on experiences, there truly is something for everyone from families to the serious amateur astronomer.

Help us celebrate the starlit skies of Downeast Maine through education, science and the arts.

Maine’s spectacular rocky coast is home to Acadia National Park, and some of the last pristine, star-filled night skies in the eastern United States. Here, the Milky Way shines bright in the largest expanse of naturally dark sky east of the Mississippi.
With the rapid loss of dark skies to light pollution receiving national attention, Maine is increasingly being referred to as one place “that still has stars.” We invite you to discover Downeast Maine’s unique commitment to protecting the quality of its starlit nights at this annual celebration

Partners and sponsors

The Acadia Night Sky Festival is driven by volunteer power, with many individuals traveling here from far and wide to help us put on this great event. Our volunteer astronomers, from clubs all over New England, make our star parties possible. Please consider joining one of these great organizations in your area.

We would like to thank The Moorings Inn and The Bluenose Inn for providing accommodation for our speakers and volunteers during their stay here and for their support of this important community event in 2017.
