An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysics, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant or Stonehenge.
The Cerro Tololo Inter-American Observatory (CTIO) is an astronomical observatory located on the summit of Mt.Cerro Tololo in the Coquimbo Region of northern Chile, with additional facilities located on Mt. Cerro Pachón about 10 kilometres (6.2 mi) to the southeast. It is approximately 80 kilometres (50 mi) east of La Serena, where support facilities are located. The site was identified by a team of scientists from Chile and the United States in 1959, and it was selected in 1962. Construction began in 1963 and regular astronomical observations commenced in 1965. Construction of large buildings on Cerro Tololo ended with the completion of the Víctor Blanco Telescope in 1974, but smaller facilities have been built since then. Cerro Pachón is still under development, with two large telescopes inaugurated since 2000, and one in the final stages of construction as of 2023
Carlos Torres (1929–2011) was a Chilean astronomer of the University of Chile and an individual member of the International Astronomical Union on several commissions. Between 1968 and 1982, he discovered or co-discovered a number of asteroids from the University of Chile's Cerro El Roble Astronomical Station. Together with Spanish astronomer Carlos Guillermo Torres (1910–1965), he was honored with the naming of asteroid 1769 Carlostorres.
Paranal Observatory is an astronomical observatory operated by the European Southern Observatory (ESO). It is located in the Atacama Desert of Northern Chile on Cerro Paranal at 2,635 m (8,645 ft) altitude, 120 km (70 mi) south of Antofagasta. By total light-collecting area, it is the largest optical-infrared observatory in the Southern Hemisphere; worldwide, it is second to the Mauna Kea Observatory on Hawaii.
Llano de Chajnantor Observatory is the name for a group of astronomical observatories located at an altitude of over 4,800 m (15,700 ft) in the Atacama Desert of northern Chile. The site is in the Antofagasta Region approximately 50 kilometres (31 mi) east of the town of San Pedro de Atacama. The exceptionally arid climate of the area is inhospitable to humans, but creates an excellent location for millimeter, submillimeter, and mid-infrared astronomy. This is because water vapour absorbs and attenuates submillimetre radiation. Llano de Chajnantor is home to the largest and most expensive astronomical telescope project in the world, the Atacama Large Millimeter Array (ALMA). Llano de Chajnantor and the surrounding area has been designated as the Chajnantor Science Reserve by the government of Chile.
La Campana National Park is located in the Cordillera de la Costa, Quillota Province, in the Valparaíso Region of Chile. La Campana National Park and the Vizcachas Mountains lie northwest of Santiago. This national park covers approximately 80 square kilometres (31 sq mi) and is home to one of the last palm forests of Jubaea chilensis, which prehistorically had a much wider distribution than at present. Another attraction is the Cerro La Campana, which lends its name to the park. In 1834 Charles Darwin climbed this mountain, during the second voyage of HMS Beagle.
La Campana-Peñuelas is a Biosphere Reserve located in west-central Chile. which includes La Campana National Park and the Lago Peñuelas National Reserve. Forests within the La Campana-Peñuelas are habitats for the Chilean Wine Palm, Jubaea chilensis, an endangered palm, which had a much broader distribution prior to modern times.
Cerro Pachón is a mountain in Chile.
2518 Rutllant, provisional designation 1974 FG, is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 4 kilometers in diameter. It was discovered by Chilean astronomer Carlos Torres at the Cerro El Roble Station of the National Astronomical Observatory in Chile, on 22 March 1974, and named for astronomer Federico Alcina.
2013 Tucapel, provisional designation 1971 UH4, is an eccentric Florian asteroid from the inner regions of the asteroid belt, approximately 11 kilometers in diameter. It was discovered on 22 October 1971, by the University of Chile's National Astronomical Observatory at Cerro El Roble Astronomical Station. It was named for one of the indigenous Mapuche chiefs.
In 2011, Chile was home to 42% of the world's astronomical infrastructure, consisting principally of telescopes. In 2015, it was estimated that Chile would contain more than 50% of the global astronomical infrastructure by 2030. In the Atacama desert region of northern Chile, the skies are exceptionally clear and dry for more than 300 days of the year. These conditions have attracted the world's scientific community to develop highly ambitious astronomical projects in the Atacama desert.
Víctor Manuel Blanco was a Puerto Rican astronomer who in 1959 discovered Blanco 1, a galactic cluster. Blanco was the second Director of the Cerro Tololo Inter-American Observatory in Chile, which had the largest telescope in the Southern Hemisphere at the time. In 1995, the 4-meter telescope was dedicated in his honor and named the Víctor M. Blanco Telescope; it is also known as the "Blanco 4m."
The Víctor M. Blanco Telescope, also known as the Blanco 4m, is a 4-metre aperture telescope located at the Cerro Tololo Inter-American Observatory, Chile on the summit of Mt. Cerro Tololo. Commissioned in 1974 and completed in 1976, the telescope is identical to the Mayall 4m telescope located on Kitt Peak. In 1995 it was dedicated and named in honour of Puerto Rican astronomer Víctor Manuel Blanco. It was the largest optical telescope in the Southern hemisphere from 1976 until 1998, when the first 8-metre telescope of the ESO Very Large Telescope opened.
The Calán/Tololo Supernova Survey was a supernova survey that ran from 1989 to 1995 at the University of Chile and the Cerro Tololo Inter-American Observatory to measure a Hubble diagram out to redshifts of 0.1. It was founded by Mario Hamuy, José Maza Sancho, Mark M. Phillips, and Nicholas B. Suntzeff in 1989 out of discussions at the UC Santa Cruz meeting on supernovae on how to improve the Hubble diagram using Type Ia supernovae. It was also motivated by the suggestion of Allan Sandage to restart a supernova survey after the Sandage and Tammann survey failed due to poor quality photographic plates in 1986. The Survey built on the original supernova survey of Maza done at the f/3 Maksutov Camera at the Cerro Roble Observatory of the University of Chile between 1979 and 1984. The Survey used the CTIO Curtis Schmidt telescope with IIa-O photographic plates, each plate covering a field of 25 sq-deg on the sky. The plates were developed and sent to Santiago Chile the next morning and searched for supernovae at the Department of Astronomy at the University of Chile. Any supernova candidates were then observed the next night using the 0.9m telescope at CTIO with a CCD camera. This was one of the first studies done in astronomy where the telescope time was scheduled to observe objects not yet discovered.
Cerro Armazones is a mountain located in the Sierra Vicuña Mackenna of the Chilean Coast Range of Andes, approximately 130 km (81 mi) south-east of Antofagasta in the Antofagasta Region, Chile. The mountain is located in a privileged zone for optical astronomy because it has 89% cloudless nights a year. On 26 April 2010, the European Southern Observatory Council selected Cerro Armazones as the site for the planned Extremely Large Telescope (ELT); the construction began in June 2014, and the first light is expected in 2027. Before the construction of the ELT began, the elevation of Cerro Armazones had been 3,064 metres (10,052 ft), but now the top is truncated and the resulting plateau is several meters lower.
Cerro Armazones Observatory is an international astrophysical project hosted by the ESO Paranal Observatory and operated by the Nicolaus Copernicus Astronomical Center of the Polish Academy of Sciences. The observatory is located on Cerro Murphy, which is a hill located 1 kilometre (0.62 mi) to the southwest and 230 metres (750 ft) below the summit of Cerro Armazones, a mountain in the Antofagasta Region of Chile, 120 km (75 mi) south of Antofagasta. OCM is located at 2,817 m (9,242 ft) altitude and currently houses 5 telescopes, whose diameters range between 0.3 and 1.5 m.
The Portage Lake Observatory (PLO) was an astronomical observatory owned and operated by the University of Michigan (UM). It was located near the village of Dexter, Michigan (USA), about 20 kilometers (12 mi) northwest of Ann Arbor. Construction at the site began in 1948, and the facility was closed in 1975.
