Country’s first Liquid Mirror Telescope comes up in Uttarakhand

Liquid Mirror Telescope comes up in Uttarakhand

• The first liquid mirror telescope in the country and the largest in Asia – was commissioned atop Devasthal, a hill in Uttarakhand. This will now keep a watch on the overhead sky to identify transient or variable objects such as supernovae, gravitational lenses, space debris, and asteroids.
• The scientists from the three countries spun a pool of mercury, which is a reflective liquid so that the surface curved into a parabolic shape. It is ideal for focusing light.
• A thin transparent film of mylar protects the mercury from the wind. The reflected light passes through a sophisticated multi-lens optical corrector that produces sharp images over a wide field of view. 
• A large-format electronic camera located at the focus records the images.
