Wonders of Starry Skies: Hanle Dark Sky Reserve

Astronomers study the universe by collecting faint light emitted by distant celestial objects. In order to collect such data, astronomers are forced to establish observatories in remote areas ‘untouched’ by human ‘civilization’ where the sky has not been polluted by light like our urban areas. The modest telescope at Hanle has helped Indian astronomy advance in leaps and bounds since its installation. More facilities are being developed at Hanle that will put the Indian Astronomical Observatory on the global map of the major astronomical infrastructure. Hence, it is necessary to protect the area from light pollution like other major astronomical observatories around the world.

In this regard, we are planning to implement a dark sky reserve model in Hanle to cover the entire valley and the surrounding mountains. In addition to promoting astronomy, such a sanctuary also provides opportunities to tourists and residents to appreciate the night sky as their forefathers, which is impossible in urban areas due to intense light pollution. It also provides a healthy developmental model for biodiversity and human communities. I will also showcase some beautiful nightscape pictures taken from the Dark Skies of Ladakh.
