The dry Andean air and minimal light pollution have drawn major observatories to the region, including nearby Cerro Tololo and Gemini South. The valley hosts dedicated public observatories and astro-lodges built specifically for visiting stargazers. At 30°S, the southern sky is breathtaking: the galactic core passes overhead, and the Magellanic Clouds, zodiacal light, and gegenschein are all routinely visible.
