Blue Night
Atlanta (near the center), Jacksonville (lower right) and other cities and towns in the southeastern United States light up the night sky in this view from the International Space Station. This light pollution erases the view of the stars, meteors, and the Milky Way. It also can waste money that is spent on inefficient lighting, interfere with the habits of nocturnal creatures, and cause other problems. The problem could get worse in the future as more people use bluer night lights, which create more pesky skyglow. [NASA]
