11. The Night Sky Observatory
Above the salt flats, on a far-off plateau, an old astronomical observation point provides one of the best views of the southern sky anywhere on Earth. High altitude, little light pollution, and especially dry air all provide ideal circumstances for stargazing. Stone marks and platforms matched with celestial occurrences on the site point to its use by ancient astronomers tracking seasonal changes and astronomical events. Taking use of these perfect viewing circumstances, modern astronomers have set up a research station close by. Preserved rock art illustrating constellations and astronomical events as known by indigenous people forms part of the observatory area. Guided night sky excursions combining contemporary scientific knowledge with ancient Andean cosmology let visitors experience Tracking near-Earth asteroids and researching deep space objects depend on the site, which has grown even more vital. Local schools use the observatory for instructional activities, therefore promoting new scientific ideas while helping to conserve ancient astronomical knowledge. The exact placement of stone marks indicates that the ancient viewers had advanced knowledge of astronomical motions. Studying atmospheric events and high Andes' climate patterns depends much on the observatory as well.
