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 can access the entire sky.
The Gemini South telescope is located at almost 9,000’ elevation
on a mountain in the Chilean Andes called Cerro Pachón.
Cerro Pachón shares resources with the adjacent SOAR Telescope
and the nearby telescopes of the Cerro Tololo Inter-American Observatory.
The Frederick C. Gillett Gemini North Telescope is located
on Hawaii's Mauna Kea as part of the international community of observatories
that have been built to take advantage of the superb atmospheric
conditions on this long dormant volcano that rises almost 14,000'
into the dry, stable air of the Pacific. The Gemini Observatory’s
international headquarters is located in Hilo, Hawaii at the University
of Hawaii at Hilo’s University Park.
Both of the Gemini telescopes have been designed to take advantage
the latest technology and thermal controls to excel in a wide variety
of optical and infrared capabilities. One example of this is the
unique Gemini coating chamber that uses "sputtering" technology
to apply protected silver coatings on the Gemini mirrors to provide
unprecedented infrared performance.
Gemini’s aggressive instrument program keeps the observatory
at the cutting edge of astronomical research. By incorporating
technologies such as laser guide stars, Multi-Conjugate Adaptive
Optics and multi-object spectroscopy, astronomers in the Gemini partnership
have access to the latest tools for exploring the universe. For
the latest information of Gemini’s future instrumentation see:
Scientific Horizons at the Gemini Observatory.
Gemini was built and is operated by a partnership of 7 countries
including the United States, United Kingdom, Canada, Chile, Australia,
Brazil and Argentina. Any astronomer in each partner country can
apply for time on Gemini with is allocated in accordance with the
amount of financial support provided by each country.
The Gemini telescopes have been integrated with modern networking
technologies to allow remote operations from control rooms at the
facilities in Hilo and La Serena Chile. With the flexibility of “Queue
Scheduling” and remote participation, researchers anywhere
in the Gemini partnership will be assured the best possible match
between observation, instrument and observing conditions.
