Africa by night
"Led by Nasa and other organizations, it shows different social, geographical and economical evidences of the five continents, according to the amount of light they cast out.
Taken between 1993 and 2002, the pictures also explicit the evolution of energy spent along the years. The red dots, for instance, indicate recent lights, while the blue ones represent already extinct sources. Even though conceived with no artistic intentions, the study images are, to say the least, pretty amazing."
