✅India’s first liquid-mirror telescope- International Liquid Mirror Telescope
(ILMT) has now entered the commissioning phase and will start scientific
observations some time in October this year.
About
✅It is located at an altitude of 2,450 metres on
the Devasthal Observatory campus of the Aryabhata Research Institute of Observational Sciences (ARIES) in Nainital district, an autonomous institute under the Department of Science and Technology.
✅Built by : Astronomers from India, Belgium and Canada
✅Features : The telescope will help in surveying the sky, making it possible
to observe several galaxies and other astronomical sources just by staring at
the strip of sky that passes overhead.
✅For this, the telescope employs a 4 meter diameter rotating mirror made up of a thin film of liquid mercury to collect and focus light.
✅Duration : The ILMT will operate every night for five years and carry out daily imaging except between June and August monsoon months, as a precaution to protect the instruments from humid conditions.
✅ Significance : It is the first liquid mirror telescope in the country and the largest in Asia.

✅Remember : ILMT will be the third telescope to be operating from Devasthal after the 3.6-metre Devasthal Optical Telescope (DOT) — the largest in India commissioned in 2016 — and the 1.3-metre Devasthal Fast Optical Telescope (DFOT) inaugurated in 2010.
