Fivethirtyeight.com sent editor Oliver Roeder to what looks to be the darkest spot in the United States: Gerlach, Nev.

A NASA satellite studying light all around Earth photographed our rock, and found that there are only a very few small areas in the U.S. without light pollution.

Roeder's story looks at the dangers of light pollution, as well as the sky above Gerlach.

Ah, rural Nevada. Dark physically as well as intellectually.
