The next milestone in telescope size is likely to be one with a primary mirror 30 meters in diameter, which would provide ten times the light-gathering area of each of the Kecks. The University of California and the California Institute of Technology (Caltech) have teamed up to design and build a 30-meter telescope, dubbed the California Extremely Large Telescope (CELT).
SANTA CRUZ, CA--The desire for ever larger telescopes has driven astronomers relentlessly for nearly 400 years. In 1610, Galileo discovered the moons of Jupiter using a telescope with a lens not much more than an inch in diameter. Today, the largest optical telescopes are the twin Keck Telescopes in Hawaii, with 10-meter mirrors that gather the faint light from distant galaxies. But, of course, astronomers still want bigger telescopes, knowing they can yield new insights into the nature and origins of the universe.
