The first liquid mirror telescope in the country and the largest in Asia was commissioned atop Devasthal, a hill in Uttarakhand.
This will now keep a watch on the overhead sky to identify transient or variable objects such as supernovae, gravitational lenses, space debris, and asteroids.
The Indian Liquid Mirror Telescope (ILMT) will help in surveying the sky.
It makes it possible to observe several galaxies and other astronomical sources.
