Dark Sky Reserve | UPSC Daily Current Affairs 2023

GS 3
Context:
👉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.
👉It is the partnership of Ladakh Autonomous Hill Development Council (LAHDC), Leh, and the Indian Institute of Astrophysics (IIA), Bengaluru.

✍What is dark-sky-reserve?
👉A dark-sky reserve is an area, usually surrounding a park or observatory, that restricts artificial light pollution. The purpose of the dark-sky movement is generally to promote astronomy and avoid interference during astronomical observations.
👉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 exist around the world but none so far in India.
👉Why Hanle?
Located atop Mt. Saraswati in the Nilamkhul Plain in the Hanle Valley of Changthang, it is a dry, cold desert with a sparse human population and has the Hanle monastery as its nearest neighbour. The cloudless skies and low atmospheric water vapour make it one of the best sites in the world for optical, infrared, sub-millimetre, and millimetre
wavelengths.
