Lowell Observatory

(loh -wĕl) A privately owned observatory at Flagstaff, Arizona, at an altitude of 2210 meters, set up by the US astronomer Percival Lowell in 1895. For many years it was the site of the huge Clark Telescope, a 24-inch (60.96-cm) refractor that was the largest of its generation. The US astronomer Clyde W. Tombaugh discovered the planet Pluto in 1930 while working at the Lowell Observatory. Currently the observatory's researchers work at Anderson Mesa, south of Flagstaff. But the Lowell Observatory is planned to be home to a 4-meter-class reflector, the Discovery Channel Telescope, which astronomers hope will be operational by about 2008.
