Acadia Night Sky Festival
September 25-29, 2019
Celebrating the starlit skies of Downeast Maine
Join us for the 11th Annual Acadia Night Sky Festival
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 25-29, 2019, 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 River.
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.

About the Festival
The Acadia Night Sky Festival originated as an outcome of the enthusiasm of the local community and government over the adoption of a local ordinance. In 2007, the Bar Harbor Conservation Commission (BHCC), held their biennial Conservation Summit; it was here that the need to preserve the night skies over Mount Desert Island and its surrounding communities as the darkest skies on the Eastern seaboard, was first brought to light. As a result, the BHCC proceeded to develop over the course of the following two years a local ordinance that required ‘night sky friendly’ outdoor lighting on all new construction in the town of Bar Harbor, in an effort to prevent any further light pollution to our local skies.
The popularity of this effort among both local communities and government drew such incredible support that in 2009, the ‘Bar Harbor Ordinance – Light and Glare’ was voted in by a landslide popular vote. Recognizing the overwhelming response from the residents and respective municipalities, the need to celebrate this wonderful commodity became apparent, and that same year, the inaugural Acadia Night Sky Festival was held.
Since its inaugural run, the Acadia Night Sky Festival has attracted much national attention and recognition, not only for its unique purpose, but for the collaboration that it has inspired among some of the major private organizations in Hancock County. The current ANSF planning committee is made up of representatives from Acadia National Park, Beal’s Lobster Pier, The Jackson Laboratory, Jesup Memorial Library, Mount Desert Island High School and the Bar Harbor Chamber of Commerce.
Our mission is to protect and enjoy Acadia’s stellar night sky as a valuable natural resource through education, science and the arts.
