Gemini North telescope dome on the summit of Mauna Kea, Hawaii, USA, at sunset. This 8-metre optical/infrared telescope was completed in 1999. Here the side vents are open to regulate the telescope's temperature and ensure a smooth flow of air above the primary mirror. Gemini North's twin telescope, Gemini South is located in Cerro Pachon, Chile. Together, the two telescopes give coverage of virtually the entire night sky.
