Crescent Moon Rising and Earth's Atmosphere
On Feb. 1, 2014, Japan Aerospace Exploration Agency astronaut Koichi Wakata tweeted this view of a crescent moon rising and the cusp of Earth's atmosphere. Distinct colors are visible because the dominant gases and particles in each layer of the atmosphere act as prisms, filtering out certain colors of light.
