Composite Image of Earth at Night

Astronomy photo of the day. I generally don't post pics from other sites but I want to capture this one so that in 50 years I can compare it to a similar picture. Very cool shot of the earth at night. Composite image made via sattelite. Comments from the site that posted the picture:

Explanation: This is what the Earth looks like at night. Can you find your favorite country or city? Surprisingly, city lights make this task quite possible. Human-made lights highlight particularly developed or populated areas of the Earth's surface, including the seaboards of Europe, the eastern United States, and Japan. Many large cities are located near rivers or oceans so that they can exchange goods cheaply by boat. Particularly dark areas include the central parts of South America, Africa, Asia, and Australia. The above image is actually a composite of hundreds of pictures made by the orbiting DMSP satellites.
