Test ranges, observatories and ground stations are a hand-picked list kept in this project rather than a published catalogue: no catalogue answers which of the world's thousands of observing sites belong on a map of it. The article below is what lets the choice be argued with.

## What it is

The Kitt Peak National Observatory (KPNO) is a United States astronomical observatory located on Kitt Peak of the Quinlan Mountains in the Arizona-Sonoran Desert on the Tohono Oʼodham Nation, 88 kilometers (55 mi) west-southwest of Tucson, Arizona. With more than twenty optical and two radio telescopes, it is one of the largest gatherings of astronomical instruments in the Earth's northern hemisphere.
