Gemini South Telescope

The Gemini South Telescope is located at almost 9,000' elevation on a mountain in the Chilean Andes called Cerro Pachon. Cerro Pachon shares resources with the adjacent SOAR Telescope and the nearby telescopes of the Cerro Tololo Inter-American Observatory. The Gemini Observatory consists of twin 8-meter optical/infrared telescopes located on two of the best sites on our planet for observing the universe. Together these telescopes, Gemini South & Gemini North, can access the entire sky.

The Gemini Observatory's international headquarters is located in Hilo, Hawaii at the University of Hawaii at Hilo's University Park. Built by an international partnership of seven nations, Gemini North is the first of two 8-meter telescopes that together can explore the entire northern and southern skies in optical and infrared light. Its twin, Gemini South, is under construction on Cerro Pachón in northern Chile. They are expected to obtain unprecedented optical and infrared views of stars, galaxies, and the most distant outposts of the known universe.

The Gemini Observatory is operated by the Association of Universities for Research in Astronomy, Inc., under a cooperative agreement with the NSF on behalf of the Gemini partnership: the National Science Foundation (United States), the Science and Technology Facilities Council (United Kingdom), the National Research Council (Canada), CONICYT (Chile), the Australian Research Council (Australia), Ministério da Ciência e Tecnologia (Brazil), and Ministerio de Ciencia, Tecnología e Innovación Productiva (Argentina)

Gemini South Observatory - Overview Last Updated on 2009-08-26 00:00:00 The Gemini South Observatory consists of one 8.1-meter diameter, altitude-azimuth mounted telescopes. The telescope has a suite of instruments covering the optical and ground-accessible infrared wavelength regions. Several instruments are simultaneously mounted at the cassegrain focus, giving the observatory great flexibility in adapting to changing weather conditions, observing multiple programs requiring different instruments in one night, and making time-critical measurements including responding within minutes to notifications to observe rapid transients such as gamma-ray bursts. (The Gemini North Observatory has essentially the same set-up.) The Gemini telescopes were designed and built with two principal performance goals in mind. To provide the best image quality possible from the ground for telescopes of their size. To provide the cleanest possible (i.e., lowest possible... More »
