Earth at Twilight
Day transitions to night gradually on Earth, as shown in this image of the terminator line. The Sun, illuminating from the right, casts a soft light on the clouds. This light is filtered through the dusty troposphere, Earth's lowest atmospheric layer. Higher altitudes show a clear, bright layer as the sun sets.
