Lowell Observatory technology to be telecast on the Discovery channels. The primary mirror of the Discovery Channel Telescope will be in diameter, with an uncommon meniscus design for such a large mirror. This mirror was ground and polished into its parabolic shape at the Optical Fabrication and Engineering Facility of the College of Optical Sciences of the University of Arizona (in Tucson, Arizona). Lowell Observatory's astronomers conduct research on a wide range of solar system and astrophysical topics using ground-based, airborne, and space-based telescopes. Among the many current programs are a search for near-Earth asteroids, a survey of the Kuiper Belt beyond
Lowell Observatory and Chile. Past Anderson Mesa, on the peak of Happy Jack, Lowell Observatory has also built and is commissioning the Discovery Channel Telescope in partnership with Discovery Communications, Inc. The observatory has carried out a wide array of research. One of its programs was the measurement of the variability of solar irradiance. When Harold L. Johnson took over as the director in 1952, the stated objective became to focus on light from the Sun reflecting from Uranus and Neptune. In 1953, the current telescope was erected. Beginning in 1954, this telescope began monitoring the brightness of these two planets, and
