In a first-of-its-kind initiative, the Department of Science & Technology (DST) has announced the setting up of India’s first Dark Sky Reserve in Hanle, Ladakh in the next three months.
Hanle, which is about 4,500 metres above sea level, hosts telescopes and is regarded as one of the world’s most optimal sites for astronomical observations. However, ensuring that the site remains well-suited for astronomy implies keeping the night-sky pristine, or ensuring minimal interference to the telescopes from artificial light sources such as electric lights and vehicular lights from the ground.
A Dark Sky Reserve is a designation given to a place that has policies in place to ensure that a tract of land or region has minimal artificial light interference. The International Dark Sky Association is a U.S.-based non-profit that designates places as International Dark Sky Places, Parks, Sanctuaries and Reserves, depending on the criteria they meet. Several such reserves exists around the world but none so far in India.
