Lowell Observatory


Founded in 1894 and today a National Historic Landmark, Lowell Observatory is where astronomer Clyde Tombaugh discovered Pluto in 1930. Its hands-on exhibit hall lets you peer through mighty telescopes, including a specially equipped solar one. The Steele Visitors Center has evening multimedia presentations on constellations and deep-sky objects, and the SlipherVision “immersive space theater” offers planetarium shows. Guided tours take place several times daily.
