Liquid Mirror Telescope, Uttarakhand is a 4-meter telescope in Uttarakhand. It is the first liquid-mirror telescope for astronomy in the world[1] and the largest liquid-mirror telescope in Asia.[2]
On 2 June 2022, the telescope saw its first light.[3] On 12 June 2022, it came online.[4] On 21 June 2022, it became ready to observe.[5] On 21 March 2023, it was inaugurated by Jitendra Singh.[6]
The telescope uses elemental mercury as its mirror surface.[7] The mercury is rotated about the axis of the telescope, and due to centrifugal force, takes a parabolic shape to focus incoming light.[8]
