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, Indiana of the Great Lakes Basin, Lowell sought permission to pipe in lake water to replace city water drawn from its high fluoride deep wells. However, diversion of water out of the Great Lakes requires the approval of the Great Lakes Commission, which includes representatives of all the US states and Canadian provinces that border on the lakes. Lowell's request was turned down in 1991. Lowell lies on the Valparaiso Moraine, almost on the Kankakee Outwash Plain. The town also lies near the St. Lawrence Seaway Divide. Lowell has a Humid continental climate (Köppen climate classification Dfa) with four distinct seasons.
