India’s first ‘dark sky reserve’ or night sky sanctuary will be opened for tourists in upcoming summer.

Situated at one of the world’s highest-located sites for optical, infrared, and gamma-ray telescopes, Hanle in Ladakh, is a part of Changthang Wildlife Sanctuary. The site aims to have activities which will help in building and boosting local tourism and economy via science.

The Hanle reserve is located around the Indian Astronomical Observatory (IAO) of the Indian Institute of Astrophysics (IIA) spread over 1,073 sq km.

Although professional and amateur astronomers have been organising treks to secluded areas to observe the night sky, the Hanle reserve is unique because it not only promotes the eco-friendly activity of eco-tourism but also aims to reduce artificial light pollution for the purposes of wildlife conservation, spreading awareness and education about astronomy, and strengthening scientific research.

Notably, Hanle reserve is not India’s first astro tourism spot. We have the renowned Jantar Mantar in Jaipur but Hanle Dark Sky Reserve (HDSR) will surely be India’s first designated dark sky reserve.

The International Dark Sky Association (IDSA) defines an international dark sky reserve (IDSR) as “a public or private land of substantial size (at least 700 km², or about 173,000 acres) possessing an exceptional or distinguished quality of starry nights and nocturnal environment, and that is specifically protected for its scientific, natural, educational, cultural heritage, and/or public enjoyment.”

A dark sky reserve requires a “core” area that has clear sky without any light pollution, which can enable telescopes to see the sky in its natural darkness. To support the core, it should be surrounded by a “peripheral” or “buffer” area that supports dark sky values in the core while receiving the same benefits.

Hanle is located in Ladakh’s cold desert region – away from any form of human disturbance and nature at its best. Clear sky conditions and dry weather which almost exist throughout the years, also make Hanle the right decision. For all astronomical observations and sky-gazing techniques, Hanle makes it the best.

Once HDSR is set up, both locals and tourists will follow the regulations imposed on the outdoor lighting, use of high beam vehicle headlights, light-reflecting shields and dark curtains among other things to reduce light pollution and other unwanted illumination.
