Night sky above Andean ice field from the Chajnantor Plateau, at an altitude of 5000 meters in the Chilean Andes. Licancabur, a very symmetrical volcano that reaches 5920 meters, is pictured in this view from the border of Chile and Bolivia. The ice field in the foreground is a feature of high-altitude Andean areas known as ice penitentes. The bright star on the left is Vega in the constellation Lyra.
