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.
