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 (.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 Clark and then shipped by train to Flagstaff. The telescope is listed as a national historic landmark.

Current research

Current research at Lowell Observatory focuses primarily on solar system objects. LONEOS (Lowell Observatory Near-Earth-Object Search) is an ongoing search that scans the sky for comets and asteroids that could potentially impact the Earth in the future. Other research programs include searches for Kuiper Belt Objects, extrasolar planets, and planetary satellites. Staff astronomers at the observatory also study the formation, evolution, and properties of stars. They also study the interstellar medium and star formation and evolutionary processes in the Milky Way and other galaxies.
