Star trails. Time exposure photograph of stars above ponderosa pine trees and eroded rock. The streaks of light result from the rotation of the Earth in relation to the fixed stars. The pink hue of the sky is due to the aurora borealis (or northern lights),caused by charged particles from the Sun interacting with the upper atmosphere.
