Photo by babaktafreshi / This hour-long night exposure from the White Mountains, in New Hampshire, shows star trails from Earth's rotation, with the North Star, or Polaris, near the top. This is one of the few photos I have in the newly released National Geographic book, America the Beautiful, with 250 photos from Nat Geo photo archive, spanning 130 years, and inspiring words by a famous citizen from each state.
