Gemini Observatory
What Does Gemini Observatory Do?
Gemini Observatory is an astronomical observatory consisting of two 8.1-meter (26.6 ft) optical/infrared telescopes located on two separate mountains: Gemini North on Mauna Kea in Hawaiʻi, USA, and Gemini South on Cerro Pachón in Chile. Together, these telescopes provide near-complete coverage of both the northern and southern skies. Gemini Observatory is operated by the National Science Foundation's NOIRLab under an international agreement with the United States, Canada, Chile, Brazil, Argentina, and South Korea. It enables astronomers to explore the universe, from our solar system to distant galaxies, supporting a wide range of astrophysical research.
