The blue band on the horizon is the shadow of the Earth cast onto the atmosphere opposite the sunset point. The pink Belt of Venus above the shadow is from red sunlight still illuminating the upper atmosphere, an effect that lasts only a few minutes at sunset or sunrise, and requires a very clear sky to show up, as it was this night.13898781 - Mars (bottom) and Saturn in conjunction at right, and the Milky Way at left, in deep blue twilight before the sky got filly dark, over the old corral of the 76 Ranch, in Grasslands National Park, Saskatchewan, August 27/28, 2014.
