Project
LBT, originally named the Columbus Project. it is a joint project of these members: the Italian astronomical community (represented by the Istituto Nazionale di Astrofisica, INAF); the University of Arizona; University of Minnesota, University of Notre Dame, University of Virginia, the LBT Beteiligungsgesellschaft in Germany (Max Planck Institute for Astronomy in Heidelberg, Landessternwarte in Heidelberg, Leibniz Institute for Astrophysics Potsdam (AIP), Max Planck Institute for Extraterrestrial Physics in Munich and Max Planck Institute for Radio Astronomy in Bonn); The Ohio State University; Research Corporation in Tucson.
The telescope design has two 8.4-meter (28 ft) mirrors mounted on a common base, hence the name "binocular". LBT takes advantage of active and adaptive optics, provided by Arcetri Observatory. The collecting area is two 8.4 meter aperture mirrors, which works out to about 111m2 combined. This area is equivalent to an 11.8 meters (39 ft) circular aperture, which would be greater than any other single telescope, but it is not comparable in many respects since the light is collected at a lower diffraction limit and is not combined in the same way. Also, an interferometric mode will be available, with a maximum baseline of 22.8 meters (75 ft) for aperture synthesis imaging observations and a baseline of 15 meters (49 ft) for nulling interferometry. This feature is along one axis with the LBTI instrument at wavelengths of 2.9 - 13 micrometres, which is the near infrared.

Famous quotes containing the word project:
“Indigenous to Minnesota, and almost completely ignored by its people, are the stark, unornamented, functional clusters of concrete—Minnesota’s grain elevators. These may be said to express unconsciously all the principles of modernism, being built for use only, with little regard for the tenets of esthetic design.”
—Federal Writers’ Project Of The Wor, U.S. public relief program (1935-1943)
“Although I mean it, and project the meaning
As hard as I can into its brushed-metal surface,
It cannot, in this deteriorating climate, pick up
Where I leave off.”
—John Ashbery (b. 1927)
“... one of art photography’s most vigorous enterprises—[is] concentrating on victims, on the unfortunate—but without the compassionate purpose that such a project is expected to serve.”
—Susan Sontag (b. 1933)
