The International Liquid Mirror Telescope is a 4-meter telescope located inside the premises of Aryabhatta Research Institute of Observational Sciences (ARIES) in the city of Nainital, Uttarakhand, India. It is the first liquid-mirror telescope for astronomy in Asia and currently the largest liquid-mirror telescope in the world [1] after the decommissioning of the Large Zenith Telescope.

History

On 2 June 2022, the telescope saw its first light. [2] On 12 June 2022, it came online. [3] On 21 June 2022, it became ready to observe. [4] On 21 March 2023, it was inaugurated by Jitendra Singh. [5]

Mechanism

The telescope uses elemental mercury as its mirror surface. [6] The mercury is rotated about the axis of the telescope, and due to centrifugal force, takes a parabolic shape to focus incoming light. [7]
