Sunset from Earth orbit, seen from the International Space Station (ISS). The glow of the setting Sun is lighting up the atmosphere (blue) on the gently curving horizon that separates the Earth (bottom) from space (top). The atmosphere is around 100 kilometres thick, a relatively thin layer of air compared to the size of the Earth itself. Photographed on 23 November 2009 during mission STS-129 by the Space Shuttle Atlantis to the ISS.
