Asia's largest 4-meter telescope inaugurated in Uttarakhand
Asia's largest 4-meter International Liquid Mirror Telescope was launched in Devasthal in Uttarakhand on 21 March.
An overview of the news
The telescope was officially inaugurated by Science and Technology Minister Jitendra Singh.
It has been established at the Aryabhatta Research Institute of Observational Sciences (ARIES) located in Nainital, Uttarakhand.
The observatory will explore the deep sky, collecting an assortment of objects ranging from asteroids to supernovae and space debris.
About the International Liquid Mirror Telescope
It consists of a 4-metre-diameter rotating mirror made of a thin layer of liquid mercury to collect light.
It mainly consists of three components.
The first bowl contains a reflective liquid metal (mercury).
The second air pressure driven motor on which the liquid mirror rests.
Third is a system to run the motor. The surface of liquid mirror binoculars naturally takes on a parabolic shape as it rotates, which is ideal for focusing light.
A thin transparent film of micellar liquid protects the mercury from wind abrasion, which can create ripples on the surface of the mercury.
The reflected light passes through a sophisticated multi lens optical corrector which produces clear images over a wide field of view.
Why was the telescope made?
It is designed to survey the night sky and detect variable and transient objects such as supernovae, space debris and gravitational lenses.
Through its data, the telescope can analyze objects in the sky using machine learning and artificial intelligence.
