No sudden, sharp boundary marks the passage of day into night in this view of ocean and clouds over Earth. Instead, the shadow line or terminator is diffused and shows the gradual transition to darkness we experience as twilight. With the sun illuminating the scene from the right, the cloud tops reflect gently reddened sunlight filtered through the dusty troposphere, the lowest layer of the planet’s atmosphere. A clear high-altitude layer, visible along the day side’s upper edge, scatters blue sunlight and fades into the blackness of space. This picture actually is a single digital photograph taken in June of 2001 from the International Space Station orbiting at an altitude of 211 nautical miles.
