Thanks to Bob Bopp, who explains ” This is from NASA’s photo of the day site. It shows the Skogarfoss waterfall in Iceland. The colorful arc of light on the left is due to drops that have drifted off from the waterfall and are now illuminated by the nearly full Moon. High above are the faint green streaks of aurora. In the background is a beautiful starscape that includes the Big Dipper.”
