Concept:The first liquid mirror telescope in India, and the largest in Asia, was commissioned at a specific location in the Himalayan region.
Explanation:The Indian Liquid Mirror Telescope (ILMT) uses a rotating mirror made of a thin liquid mercury film.
It is a 4-meter diameter telescope designed to survey the sky for transient objects like supernovae, asteroids, and space debris.
The telescope was built by astronomers from India, Belgium, and Canada.
It is installed at the Devasthal Observatory, which is part of the Aryabhatt Research Institute of Observational Sciences (ARIES).
This observatory is located in the Nainital district of Uttarakhand, at an altitude of 2,450 metres.
Uttarakhand thus hosts the ILMT along with the Devasthal Optical Telescope (DOT).
The ILMT was designed and built by the Advanced Mechanical and Optical Systems (AMOS) Corporation and the Centre Spatial de Liege in Belgium.
It keeps a watch on the overhead sky to identify variable objects and helps survey several galaxies.
