Earl Brechlin of the Mount Desert Islander shot this video of the aurora borealis last night at Acadia National Park.
“For a handful of visitors atop Cadillac Mountain, the tallest point within 50 miles of the ocean from Maine to Rio De Janeiro, the Northern Lights appeared as a series of pale patches of light and streaks above Bar Harbor and Frenchman’s Bay,” he wrote.
The lights are caused by fast-moving electrons from the sun, which collide with and excite gases in the Earth’s atmosphere. When the particles calm back down, they give off light.
