A transit of Earth by the Moon, as photographed by the Deep Space Climate Observatory from the Sun-Earth L1 Lagrangian point. This animation was compiled from a set of 60 frames—20 distinct images, each compiled from monochrome images taken in red, green and blue filters—taken over the course of five hours on July 16, 2015. Each monochrome frame was taken every 30 seconds. Due to the speed of the Moon's motion, this results in a slight green shift in some frames of the animation.
