The telescope is 600 tons of steel and glass and, today, is the largest in the world. Located in southeastern Arizona's Pinaleño Mountains, the LBT stands at just under 11,000 feet tall. It operates as part of the Mount Graham International Observatory.

Keck Observatory, astronomical observatory located near the 4,200-metre (13,800-foot) summit of Mauna Kea, a dormant volcano on north-central Hawaii Island, Hawaii, U.S. Keck's twin 10-metre (394-inch) telescopes, housed in separate domes, constitute the largest optical telescope system of the burgeoning multi- …
The main facility, located on Mars Hill just west of downtown Flagstaff, houses the original 61-centimeter (24-inch) Clark Refracting Telescope, which is now used for public education, with 85,000 annual visitors.
There are 48 astronomical observatories in the state of Arizona that have professional telescopes used for astronomy research. Some observatories are complexes that host multiple telescopes at the same site.
Situated in the Arizona Pinaleno Mountains, (Arizona is the location a disproportionate number of telescopes, presumably in part because of the geography and weather) the huge LBT, which cost over $120 million to build, had its massive mirrors crafted in the University of Arizona's nearby Steward Observatory Mirror Lab …
The largest refracting telescope in the world is at Yerkes Observatory in Williams Bay, Wisconsin. Instead of a mirror, it gathers light with a 40-inch glass lens. Astronomers also gather radio waves from space using dish-shaped antennas, the largest of which is the Arecibo Observatory in Puerto Rico.
