Construction of Gemini South in Cerro Pachon, Chile, is complete and will be celebrated by a dedication on 18 January. The telescope has moved into the instrumentation and commissioning phase. Once it catches up with its northern twin in Mauna Kea, Hawaii, the two combined will have their optical/infrared eyes on the entire sky. Gemini North and Gemini South were built for $184 million total, and they are the only telescopes in the 8-meter class that are public, meaning that any astronomer in the seven partner countries—Argentina, Australia, Brazil, Canada, Chile, the UK, and the US—can apply to use them.
