Acadia Night Sky Festival

September 21-24

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.The Acadia Night Sky Festival is one of the premiere night sky events on the eastern seaboard. The 9th Annual Festival will once again be packed with a full schedule of events to celebrate and promote the protection and enjoyment of Downeast/Acadia's stellar night sky as a valuable natural resource through education, science and the arts.
