Sunita Williams took photos of the Earth at night from the International Space Station. The photos show night falling across different regions of the world, with city lights appearing as countries enter the nighttime hours. Key areas pictured include North Africa, the Iberian Peninsula, the Alps, Iceland, the Black Sea, Red Sea, Europe, Africa, Brazil, and the eastern United States. The document urges sharing the photos widely so future generations can appreciate the spectacular views of Earth at night from space.
