Kitt Peak Nightly Observing Program

Splendors of the Universe on YOUR Night!

Clouds

Kitt Peak has an abundance of clear nights, but that doesn’t mean the clouds never move in. We hope you’ll join us again another time when our dark mountain skies are at their best!

Arizona Radio Observatory 12 Meter Telescope

Originally, a 36 foot (11 meter) radio telescope resided in this dome. Built in 1967, the 36 Foot Telescope, as it was known, was a part of the National Radio Astronomy Observatory (NRAO). In 1984, it was replaced with a slightly larger dish, and the name was changed to the 12 Meter Telescope.

In 2000, the NRAO passed control of the telescope to the University of Arizona. The University of Arizona had been operating the Submillimeter Telescope (SMT) located on Mount Graham since 1992. When it took over operations of the 12m, it created the Arizona Radio Observatory (ARO) which now runs both telescopes.

In 2013, the telescope was replaced with ESO’s ALMA prototype antenna. The new dish is the same size, but has a much better surface accuracy (thereby permitting use at shorter wavelengths), and a more precise mount with better pointing accuracy. The 12m Radio Telescope is used to study molecules in space through the use of molecular spectroscopy at millimeter wavelengths. Many of the molecules that have been discovered in the interstellar medium were discovered by the 12m.

Spacewatch

Spacewatch is the name of a group at the University of Arizona’s Lunar and Planetary Laboratory founded by Prof. Tom Gehrels and Dr. Robert S. McMillan in 1980.  Today, Spacewatch is led by Dr. Robert S. McMillan.  The original goal of Spacewatch was to explore the various populations of small objects in the solar system, and study the statistics of asteroids and comets in order to investigate the dynamical evolution of the solar system.  CCD scanning studies the Main-Belt, Centaur, Trojan, Comet, Trans-Neptunian, and Earth-approaching asteroid populations.  Spacewatch also found potential targets for interplanetary spacecraft missions. Spacewatch currently focuses primarily on followup astrometry of such targets, and especially follows up objects that might present a hazard to the Earth.
