Night Lights on Planet Earth (Western Hemisphere) Jigsaw Puzzle

This design features a beautiful image of the planet Eath taken from a satellite at night-time. It shows the areas of our planet that are densely populated and that have a large amount of street lighting, because the lights can be seen from space. The image was released by NASA in 2012 under the name "Black Marble" (a reference to NASA's earlier series of images titled "Blue Marble"). It was taken by the Suomi NPP satellite, which is said to have at least 10 times better light-resolving power than previous night-viewing satellites.
