Mount Lemmon SkyCenter is part of the University of Arizona's Department of Astronomy and operates at the top of Mount Lemmon, one of the region's tallest and most visited mountains. The SkyCenter was first established in 1956 and was at the forefront of infrared astronomy. The observatory also participated in the survey of the Moon that took place in preparation for the Apollo lunar landings. Today visitors to the SkyCenter can live a day (or night) in the life of a professional astronomer by taking part in a variety of experiences and workshops that provide up-close and personal views of the cosmos through high-tech telescopes.
