The luminous Earth at sunset: view from Apollo 9 spacecraft, March 10, 1969

"A luminous line of clouds lit by the setting Sun crowned the shore of western Australia when the photographer pointed his camera south to record that continent's appearance through an early evening haze. In the foreground, you can see a thunderstorm cell, beyond which an old cold front from the Indian Ocean was continuing to push away the clouds that marked its arrival."
