Lowell Observatory is an astronomical
observatoryin Flagstaff, Arizona. Lowell Observatory is among the oldest observatories in the United States, and was designated a National Historic Landmarkin 1965.citation|title=PDFlink| [http://pdfhost.focus.nps.gov/docs/NHLS/Text/66000172.pdf National Register of Historic Places Inventory-Nomination: Lowell Observatory] |533 KiB |author=Marilynn Larew|date=October 31, 1977|publisher=National Park Service and PDFlink| [http://pdfhost.focus.nps.gov/docs/NHLS/Photos/66000172.pdf "Accompanying six photos, exterior, from 1964 and 1976"] |880 KiB ]
The Observatory's original 24-inch
Alvan ClarkTelescope is still in use today for public education. Lowell Observatory hosts 70,000 visitors per year who take guided daytime tours and view various wonders of the night sky through the Clark Telescope and other telescopes. It was founded in 1894 by astronomer Percival Lowell, and run for a time by his third cousin Guy Lowellof Boston's well-known Lowell family. The current trustee of Lowell Observatory is William Lowell Putnam, grandnephew of founder Percival Lowell and son of long-time trustee Roger Putnam.
The observatory operates several
telescopes at two locations in Flagstaff. The main facility, located on Mars Hill just west of downtown Flagstaff, houses the original 24-inch (0.61-meter) Clark Refracting Telescope, although its role today is as a public education tool and not research. The telescope, built in 1896 for $20,000, was assembled in Boston by Alvan Clarkand then shipped by train to Flagstaff. Also located on the Mars Hill campus is the 13-inch (0.33-meter) Pluto Discovery Telescope, used by Clyde Tombaughin 1930 to discover the dwarf planet Pluto.
Lowell Observatory currently operates four research telescopes at its
Anderson Mesadark sky site, located 12 miles southeast of Flagstaff, including the 72-inch (1.8-meter) Perkins Telescope (in partnership with Boston University) and the 42-inch (1.1-meter) John S. Hall Telescope. Lowell is a partner with the United States Naval Observatoryand NRL in the Navy Prototype Optical Interferometer(NPOI) also located at that site. The Observatory also operates smaller research telescopes at its historic site on Mars Hill and in Australia and Chile. Lowell Observatory is currently building the 4.2-meter [http://www.lowell.edu/DCT Discovery Channel Telescope] in partnership with Discovery Communications, Inc.
Discovery Channel Telescope
Lowell Observatory is building a major new telescope in partnership with
Discovery Communicationsnear Happy Jack in northern Arizona. The telescope, located within the Mogollon Rim Ranger District of the Coconino National Forest, is expected to be the fifth largest in the continental United States and will allow Lowell astronomers to enter new research areas and conduct existing programs more effectively and efficiently. The DCT and the research it enables also will be the focus of ongoing informative and educational television programs about astronomy, science, and technology airing on [http://www.discovery.com Discovery networks] . In addition, the Discovery Channel Telescopeat Lowell Observatory is expected to have a significant educational and economic impact within the state.
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 Beltbeyond Neptune, a search for extrasolar planets, a decades-long study of the brightness stability of the sun, and a variety of investigations of star formation and other processes in distant galaxies. In addition, the Observatory staff designs and builds custom instrumentation for use on Lowell's telescopes and eleswhere. For example, Lowell staff built a sophisticated high-speed camera for use on the Stratospheric Observatory for Infrared Astronomy(SOFIA). SOFIA is a joint project of the United States and German space agencies and consists of a 2.5-meter telescope on board a Boeing 747 SP.
