Indian Astronomical Observatory

The Indian Astronomical Observatory operates at 4,500 meters elevation, housing optical, infrared, and gamma-ray telescopes for space research and cosmic observation.

The observatory commenced operations in 2001, marking India's entry into high-altitude astronomical research with advanced telescopic instruments for studying celestial phenomena.

The research facility maintains connections with local Ladakhi communities through educational programs that combine traditional sky-watching practices with modern astronomical discoveries.

Visitors need permits, warm clothing, and altitude acclimatization before accessing the facility, which requires coordination with the Indian Institute of Astrophysics.

The facility's location in Changthang's high-altitude desert provides 255 clear nights annually, enabling exceptional visibility for astronomical measurements and observations.
