About The Gemini Observatory

Exploring The Universe, Sharing its Wonders


The Gemini Observatory consists of twin 8.1-meter diameter optical/infrared telescopes located on two of the best observing sites on the planet. From their locations on mountains in Hawai‘i and Chile, Gemini Observatory’s telescopes can collectively access the entire sky.
Gemini was built and is operated by a partnership of five countries including the United States, Canada, Chile, Brazil, Argentina and Korea. These Participants and the University of Hawaii, which has regular access to Gemini, each maintain a “National Gemini Office” to support their local users. Any astronomer in these countries can apply for time on Gemini, which is allocated in proportion to each Partcipant's financial stake.
