Mauna Kea Observatory's Subaru and Keck Telescopes 12-03-17
The Subaru telescope is an optical-infrared telescope at the 4,200 m (13,460ft.) summit of Mauna Kea on the island of Hawaii. The telescope represents a new generation in telescope design not only because of the size of its primary mirror with an effective aperture of (27ft) 8.2 meters, but also because of the various revolutionary technologies used to achieve outstanding performance. The twin Keck Observatory telescopes are the world’s most scientifically productive optical and infrared telescopes. Each telescope weighs 300 tons and operates with nanometer precision. The telescopes’ primary mirrors are 10-meters in diameter and are each composed of 36 hexagonal segments that work in concert as a single piece of reflective glass. 2 Images Combined.
