Program to Explain Light Pollution Mapping

ELLSWORTH – Peter Lord, executive director of the Island Astronomy Institute on Mount Desert Island, will present “Starlit Communities: An Endangered Natural Resource” at 7 p.m. Tuesday, May 13, in the City Hall auditorium.

Lord will explain how light pollution mapping is used in studying Maine’s starry skies.

The Starlit Communities Project collaborates with Acadia National Park’s Night Sky Initiative to build support for municipal lighting ordinances that can balance the need for safety, security and economically feasible development with the need to diminish light pollution, protecting the view of the skies and wildlife and human health.

The program is free and open to the public and is sponsored by the League of Women Voters Downeast, the Sierra Club of Maine and the Union River Watershed Coalition.
