Subaru Telescope

About Subaru Telescope:

• It is a Japanese 8.2-metre (27-foot) optical-infrared telescope.
• It is located on the dormant volcano Mauna Kea (4,163 metres) on the island of Hawaii.
• The telescope is named for the Japanese name for the Pleiades and is operated by the National Astronomical Observatory of Japan.
• Construction on Subaru began in 1992, and the first observations were made in 1999.
• An adaptive optics system consisting of 261 actuators can change the shape of the mirror so that it is not affected by deformations caused by gravity.
• Its powerful light-collecting capability can capture weak light from celestial objects. 
• To minimize air turbulence near the telescope, the dome that surrounds the telescope is cylindrical instead of a hemisphere, as is the case with most other observatories. 
• The Subaru Telescope has observed various celestial bodies, from nearby shooting stars to galaxies located 13.1 billion light years away.
