Information:
Japan's optical telescope discovers the farthest galaxy yet known, 12.8 billions of light years distant.
Located on the summit of Mauna Kea in Hawaii, the National Astronomical Observatory of Japan began astronomical observations in 1999. An altitude of 4,200 m, a dry atmosphere, and low atmospheric pressure make the summit of Mauna Kea one of the world's best places for astronomical observations.
Based on the results of water flow tests, the Subaru Telescope was designed to allow efficient discharge of internal heat without taking in the outside air. It features a dome with a distinctive cylindrical shape.
