Hanle Dark Sky Reserve Star Party 2025

The 3rd edition of the HDSR Star Party is finally here! Scheduled from 18 - 23 September 2025, this event is open to all amateur astronomers and astrophotographers!

Indian Institute of Astrophysics, along with UT Ladakh and LAHDC Leh, has the great pleasure in inviting experienced amateur astronomers and astro-photographers to the Hanle Dark Sky Reserve (HDSR) for the HDSR Star Party 2025, between 18th and 23rd September.

Hanle Dark Sky Reserve (HDSR) is India’s first dark sky region and is centred at Hanle in the Changthang Wildlife Sanctuary around the Indian Astronomical Observatory (IAO). IAO is a research facility that is run by the Indian Institute of Astrophysics and has one of the darkest skies in India. HDSR preserves the dark skies by reducing light pollution and uses these dark skies to promote Astro-Tourism as a means to further enhance socio-economic development in the area. This is achieved through providing telescopes and training to selected villages, and these HDSR Astronomy Ambassadors function as astro-tourism guides for visitors.
