International Space Station (ISS)
Many odd looking moon photos have been captured over the years by astronauts aboard the International Space Station. Even so, this photograph, taken by the crew over Russia on May 11, 2003, must have come as a surprise. The moon which is really a quarter of a million miles away, appears to be floating inside the Earth's atmosphere. The picture is tricky because of its uneven lighting. With the sun's elevation angle at only 6 degrees, night is falling on the left side of the image while it is still broad daylight on the right side. This gradient of sunlight is the key to the illusion.
