Kitt Peak National Observatory is a United States astronomical observatory located on Kitt Peak in the Quinlan Mountains, 55 miles (88km) southwest of Tucson, Arizona, in the Sonoran Desert and the Tohono Oodham Nation. With more than twenty optical telescopes and two radio telescopes, it is one of the largest gatherings of astronomical instruments in the Northern Hemisphere. The observatory was founded in 1958, and was administered by the National Optical Astronomy Observatory from the early 1980s until 2019, after which it has been overseen by NOIRLab. This photograph, titled A Breeze of Color, shows a portion of Kitt Peak National Observatory at sunset, and was taken as part of a 2022 photographic expedition to all the NOIRLab sites.Photograph credit: Tom SlovinskRecently featured: Leucojum vernumJean RitchieUgandan kobArchiveMore featured pictures
