Aurora Borealis, Acadia National Park, Maine, 2005Photograph by Michael MelfordDarkness settles over Jordan Pond in Maine's Acadia National Park as northern lights swirl above. "It was my last night in Acadia, and I was setting up for a long exposure of starlight in the night sky," recalls photographer Michael Melford, "and this brilliant red aurora appeared. I was in a panic to make sure I caught it."
