Kitt Peak At Sunset

Sunset falls on Kitt Peak National Observatory, located near Tucson, Ariz.

The observing facilities of Kitt Peak National Observatory (KPNO) are on Kitt Peak, a 2,089-meter mountain, 90 kilometers southwest of Tucson. KPNO includes the 3.5-meter WIYN Telescope, the 4-meter Mayall Telescope and a 2.1-meter general-purpose reflector. Numerous other telescopes operated by universities or private consortia are also tenants on Kitt Peak. A full complement of state-of-the-art spectroscopic and imaging instrumentation is available for use on these telescopes.

KPNO is one of several observatories that make up the National Optical Astronomy Observatories (NOAO), a national center for research in ground-based optical and infrared astronomy, supported by the National Science Foundation. To learn more about NOAO and all of NSF's astronomy facilities, see the Special Report Eyes on the Sky.
