This is the light which turns an eclipsed moon red, as seen from the space station.
APOD: 2014 April 7 (thanks to Jeffrey Phillips in comment for alerting me to this :) )
This painting of the Earth as seen from the Moon during an eclipse is by Lucien Rudaux, space artist, living in first half of the twentieth century.For more on this, see Why a totally eclipsed moon looks red | EarthSky.org
Incidentally, this was painted long before anyone had ever visited the Moon. When most space artists were painting jagged mountains, he pointed out that the mountains were clearly rounded through a telescope, especially when silhouetted against the edge of the disk, writing: "If we reconstruct geometrically the outlines of certain lunar mountains from their observed appearance, we shall find that instead of being steep and jagged, they have quite gentle slopes and their summits are frequently flat or smoothly rounded." - The first science artist to draw accurate pictures of Mars and the Moon
"In the early morning hours of April 15, 2014, the Moon enters the Earth’s shadow, creating a total lunar eclipse. When viewed from the Moon, as in this animation, the Earth hides the Sun. A red ring, the sum of all Earth’s sunrises and sunsets, lines the Earth’s limb and casts a ruddy light on the lunar landscape. With the darkness of the eclipse, the stars come out.Nothing at all to do with blood. And this happens during every lunar eclipse.
"The city lights of North and South America are visible on the night side of the Earth. The part of the Earth visible in this animation is the part where the lunar eclipse can be seen."
