English: The
terminator is visible in this panoramic view across central South America, looking towards the north-east. An astronaut shot the photo at approximately 7:37 p.m. local time. Layers of the Earth’s
atmosphere, coloured bright
white to deep
blue, are visible on the horizon (or limb). The highest
cloud tops have a reddish glow due to direct
light from the setting
Sun, while lower clouds are in
twilight.
The
Salar de Coipasa, a large salt lake in
Bolivia, is dimly visible on the
night side of the terminator. The salar provides a geographic reference point for determining the location and viewing orientation of the image.
