In this amazing aurora picture, the crater lake in the center is called Kerid (Icelandic: Kerið) and is about 3,000 years old. The overhead view shows impressive colors and banding, with the red colors occurring higher in the Earth’s atmosphere than the green. The background sky is filled with icons of the northern night including Polaris, the Pleiades star cluster, and the stars that compose the handle of the Big Dipper.
