Telescope Atop a Volcano

Mauna Kea is a 4,205-m-high dormant volcano on Hawaii. Measured from its underwater base, Mauna Kea is 1,356m higher than Mount Everest. It ranks as the world's highest island peak. Since it is at such a high altitude, astronomers have installed a dozen large infrared telescopes on the summit of Mauna Kea.
One of the telescopes, the 10-m-wide multi-mirror Keck Telescope, is the
world's largest optical telescope, twice the size of the Hale on Mount Palomar. Completed in 1992, its huge mirror is made up of 36 hexagonal mirrors, about 1.8m across. The telescope is housed in a high protective dome. A television monitor allows astronomers to view what the telescope sees.
Situated at a height twice that of any other major observatory, viewing conditions at Mauna Kea are ideal, with calm, clear and cloudless nights throughout the year.
