Check out the bright orange moon in this photo by Stefano De Rosa. It appears orange because the white light of the Sun is scattered by the Earth's atmosphere.
As the full Moon sinks in the west, the Sun rises in the east, lighting up the snow-capped Alpine horizon.
The clouds in the sky of this snap are called noctilucent clouds. They are formed of tiny ice crystals high in the atmosphere and they only become visible during twilight. The photo was taken by Mark Shaw.
