Already home to the Indian Astronomical Observatory (IAO), operated by the Indian Institute of Astrophysics (IIA) — one of the world’s highest observatories

 Purpose and Significance Astronomy and Research: Helps scientists study celestial objects with greater clarity. Astro-Tourism: Promotes eco-friendly tourism by allowing visitors to experience pristine night skies. Environmental Protection: Reduces light pollution and preserves nocturnal wildlife behavior. Community Involvement: Local villagers are trained to use low-light systems and benefit from tourism activities.
