Astronomy:International Liquid Mirror Telescope

From HandWiki

Liquid Mirror Telescope, Uttarakhand is a 4 meters telescope in Uttarakhand which is the first liquid mirror telescope for astronomy in the world[1] and largest liquid mirror telescope in Asia.[2]

History

In 2 June 2022, the telescope saw first light coming from universe.[3] In 12 June 2022, it came online.[4] In 21 June 2022, it became ready to observe.[5] In 21 March 2023, it was inaugurated by Jitendra Singh.[6]

Mechanism

The telescope uses elemental mercury as a reflective and mirror surface.[7] The liquid mercury is rotated about the axis of the telescope, and due to the rotational force, takes a parabolic shape to focus incoming light.[8]
