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<ref>{{cite news |last=Waldek |first=Stefanie |date=2022-06-21|title=World's largest liquid mirror telescope ready to observe |work=[[Space.com]] |url=https://www.space.com/largest-liquid-mirror-telescope-opens-india|access-date=2022-06-21 }}</ref> after the decommissioning of the [[Large Zenith Telescope]].<br />
