Atacama: Stargazing Under the Clearest Sky on Earth



Few places on earth feel as mystical as the Atacama Desert in Chile. It’s been called the stargazer’s dream because of the legendary night skies. At over 8,000 feet above sea level, there’s less atmosphere between you and the stars. Even more important, the region experiences around 300 clear nights per year. With virtually no humidity and almost no light pollution, the sky reveals a level of detail most people have never seen. On a moonless night, the Milky Way stretches from horizon to horizon like a luminous river. Constellations appear sharp and three-dimensional, as satellites drift silently overhead. If you’re lucky, you might even catch a meteor streaking across the darkness, especially during annual showers like the Perseids or Geminids. Scientists have long recognized the Atacama’s unique conditions, and some of the world’s most powerful telescopes operate there. The best time to visit the Atacama Desert for stargazing is generally between March and November, when skies are clearest and rainfall is minimal.
