The Gemini Observatory consists of twin 8.1-meter diameter optical/infrared telescopes located on two of the best observing sites on the Earth, the Mauna Kea in Hawaii and the Cerro Pachon in Chile. From these mountain tops, the Gemini Observatory’s telescopes can collectively observe the entire sky with the state-of-the-art astronomical instruments.

The Gemini Observatory is operated by an international partnership of five countries including USA, Canada, Chile, Brazil, Argentina and Korea. On behalf of Korea, KASI has joined the Gemini Observatory partnership in July 2018, providing superb observering capabilities of Gemini to the entire Korean community members.

KASI is also building a new high-resolution near infrared spectrograph “IGRINS-2” that is scheduled for commissioning at Gemini South telescope in 2023.
