Gemini Overview

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 is operated by a partnership of five countries including the United States, Canada, Chile, Brazil and Argentina. The UK and Australia were formerly partners in Gemini, but have now withdrawn from the partnership in favour of ESO. In 2017 Australia will remain a limited-term partner in Gemini, with 7 classical nights in total to allocate on Gemini North and South.
