This animated globe shows the city lights of the world as they appeared to the new Suomi NPP satellite, which has at least 10 times better light-resolving power than previous night-viewing satellites.
City lights define the Nile River Valley as it snakes across the Egyptian desert. The cities of Naj’ Hamadi, Qena, and Luxor, shine the brightest. Communities in the hillsides create a thin border along either side of the valley. Simliar strips line the Nile itself. Most of Egypt’s population, and most of the country’s arable land, occupies the Nile River Valley.
