Kitt Peak Nightly Observing Program
Splendors of the Universe on YOUR Night!

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!
The Green Flash
What we call “The Green Flash” is not so much a flash as a flicker of green color, seen on the top of the sun as it sets (or rises). This rare event needs just the right atmospheric conditions.
3.5 Meter WIYN Telescope
The WIYN Observatory is owned and operated by the WIYN Consortium, which consists of the University of Wisconsin, Indiana University, National Optical Astronomy Observatory (NOAO), the University of Missouri, and Purdue University. This partnership between public and private universities and NOAO was the first of its kind. The telescope incorporates many technological breakthroughs including active optics hardware on the back of the primary mirror, which shapes the mirror perfectly, ensuring the telescope is focused precisely. The small, lightweight dome is well ventilated to follow nighttime ambient temperature. Instruments attached to the telescope allow WIYN to gather data and capture vivid astronomical images routinely of sub-arc second quality. The total moving weight of the WIYN telescope and its instruments is 35 tons. WIYN has earned a reputation in particular for its excellent image quality that is now available over a wider field than ever before through the addition of the One Degree Imager optical camera.
Many thanks to Anthony Paat for giving us a tour!
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.
