On a clear, moonless night, visitors to Great Basin National Park in Nevada can see thousands of stars, five of our solar system’s eight planets, star clusters, meteors, man-made satellites, the Andromeda Galaxy, and the Milky Way – all with the naked eye. The area boasts some of the darkest night skies left in the United States. National Park Service photo.
