MAUNA KEA OBSERVATORIES - HAWAII


The 4,200 meter high summit of Mauna Kea in Hawaii hosts the world's largest astronomical observatory for optical, infrared, and submillimeter astronomy, with telescopes operated by astronomers from eleven countries. The combined light-gathering power of the telescopes on Mauna Kea is fifteen times greater than that of the Palomar telescope in California -- for many years the world's largest -- and fifty times greater than that of the Hubble Space Telescope.
