The moon seems to be floating inside Earth's atmosphere as it was photographed by an Expedition 7 crewmember onboard the International Space Station (ISS) while above Russia. On the left side of the image, night is falling; on the right side, it's still broad daylight. This gradient of sunlight is the key to the illusion.
