(79-cm) reflecting telescopes and a 24-in. (60-cm) Schmidt telescope used in the search for asteroids and other near-earth objects. Anderson Mesa is also the site of the Navy Prototype Optical Interferometer program, a joint venture of the Lowell Observatory, the U.S. Naval Observatory, and the Naval Research Laboratory.

 work and the discovery of the expanding universe. Beginning in 1905 the observatory made a concerted search for a transneptunian planet, which led to Tombaugh's discovery of Pluto in 1930. Principal research programs involve the discovery and determination of orbits for new asteroids, a search for nearby stars, and the measurement of light and motion of close double stars, nebulae, and other galactic objects.

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.
