Byrd Green Bank Telescope , the world's largest fully steerable radio telescope . The observatory was established as the National Science Foundation 's (NSF) National Radio Astronomy Observatory (NRAO) in 1956 and made its first observations in 1958. It served as

164-449: A free market economy that saw an increase in domestic and foreign private investment, although the copper industry and other important mineral resources were not opened to competition. In a plebiscite on 5 October 1988, Pinochet was denied a second eight-year term as president (56% against 44%). Chileans elected a new president and the majority of members of a bicameral congress on 14 December 1989. Christian Democrat Patricio Aylwin ,

246-669: A national referendum in April 2020 regarding the creation of a new Constitution, later postponed to October due to the COVID-19 pandemic . On 25 October 2020, Chileans voted 78.28 per cent in favor of a new constitution, while 21.72 per cent rejected the change. Voter turnout was 51 percent. An election for the members of the Constitutional Convention was held in Chile between 15 and 16 May 2021. On 19 December 2021,

328-591: A parliamentary style democracy. However, the Civil War had also been a contest between those who favored the development of local industries and powerful Chilean banking interests, particularly the House of Edwards which had strong ties to foreign investors. Soon after, the country engaged in a vastly expensive naval arms race with Argentina that nearly led to war, as well because of the Puna de Atacama dispute . After

410-576: A plurality of votes in a three-way contest, followed by candidates Radomiro Tomic for the Christian Democrat Party and Jorge Alessandri for the Conservative Party. Allende was not elected with an absolute majority, receiving fewer than 35% of the votes. The Chilean Congress conducted a runoff vote between the leading candidates, Allende and former president Jorge Alessandri, and, keeping with tradition, chose Allende by

492-626: A campaign of domestic political and economical destabilization, some of which was backed by the United States. By early 1973, inflation was out of control. On 26 May 1973, Chile's Supreme Court, which was opposed to Allende's government, unanimously denounced Allende's disruption of the legality of the nation . Although illegal under the Chilean constitution, the court supported and strengthened Pinochet's soon-to-be seizure of power. A military coup overthrew Allende on 11 September 1973. As

574-702: A large percentage of clear nights per year, dry air, and are at high elevations. At high elevations, the Earth's atmosphere is thinner, thereby minimizing the effects of atmospheric turbulence and resulting in better astronomical " seeing ". Sites that meet the above criteria for modern observatories include the southwestern United States , Hawaii , Canary Islands , the Andes , and high mountains in Mexico such as Sierra Negra . Major optical observatories include Mauna Kea Observatory and Kitt Peak National Observatory in

656-475: A large variety of climates and landscapes. It contains 756,950 square kilometers (292,260 sq mi) of land area. It is situated within the Pacific Ring of Fire . Excluding its Pacific islands and Antarctic claim, Chile lies between latitudes 17° and 56°S , and longitudes 66° and 75°W . Chile is among the longest north–south countries in the world. If one considers only mainland territory, Chile

738-414: A leftist candidate, the 35-year-old former student protest leader Gabriel Boric , won Chile's presidential election to become the country's youngest ever leader. On 11 March 2022, Boric was sworn in as president to succeed outgoing President Sebastian Piñera. Out of 24 members of Gabriel Boric's female-majority Cabinet, 14 are women. On 4 September 2022, voters rejected the new constitution proposal in

820-593: A letter dated 12 November 1821, expressing his plan to conquer Guayaquil , the Galapagos Islands , and the Philippines . There were preparations, but the plan did not push through because O'Higgins was exiled. Chile slowly started to expand its influence and to establish its borders. By the Tantauco Treaty, the archipelago of Chiloé was incorporated in 1826. The economy began to boom due to

902-454: A particular geographic area ( European Audiovisual Observatory ). Astronomical observatories are mainly divided into four categories: space-based , airborne , ground-based, and underground-based. Historically, ground-based observatories were as simple as containing an astronomical sextant (for measuring the distance between stars ) or Stonehenge (which has some alignments on astronomical phenomena). Ground-based observatories, located on

Observatory The term observatoire has been used in French since at least 1976 to denote any institution that compiles and presents data on a particular subject (such as public health observatory ) or for

1066-555: A period of almost 24 hours, an effort that was carried on live television around the world. 2019–20 Chilean protests are a series of country-wide protests in response to a rise in the Santiago Metro 's subway fare, the increased cost of living , privatization and inequality prevalent in the country. On 15 November, most of the political parties represented in the National Congress signed an agreement to call

1148-536: A period of major reform. Under the slogan "Revolution in Liberty", the Frei administration embarked on far-reaching social and economic programs, particularly in education, housing, and agrarian reform , including rural unionization of agricultural workers. By 1967, however, Frei encountered increasing opposition from leftists, who charged that his reforms were inadequate, and from conservatives, who found them excessive. At

1230-710: A prolonged struggle, including infighting from Bernardo O'Higgins , who challenged Carrera's leadership. Intermittent warfare continued until 1817. With Carrera in prison in Argentina, O'Higgins and anti-Carrera cohort José de San Martín , hero of the Argentine War of Independence , led an army that crossed the Andes into Chile and defeated the royalists. On 12 February 1818, Chile was proclaimed an independent republic . The political revolt brought little social change, however, and 19th-century Chilean society preserved

1312-490: A reformist president, Arturo Alessandri , whose program was frustrated by a conservative congress. In the 1920s, Marxist groups with strong popular support arose. A military coup led by General Luis Altamirano in 1924 set off a period of political instability that lasted until 1932. Of the ten governments that held power in that period, the longest lasting was that of General Carlos Ibáñez del Campo , who briefly held power in 1925 and then again between 1927 and 1931 in what

1394-596: A remote 5,640 m (18,500 ft) mountaintop in the Atacama Desert of Chile. The oldest proto-observatories, in the sense of an observation post for astronomy, The oldest true observatories, in the sense of a specialized research institute , include: Space-based observatories are telescopes or other instruments that are located in outer space , many in orbit around the Earth. Space telescopes can be used to observe astronomical objects at wavelengths of

1476-740: A vote of 153 to 35. Frei refused to form an alliance with Alessandri to oppose Allende, on the grounds that the Christian Democrats were a workers' party and could not make common cause with the right wing. An economic depression that began in 1972 was exacerbated by capital flight , plummeting private investment, and withdrawal of bank deposits in response to Allende's socialist program. Production fell and unemployment rose. Allende adopted measures including price freezes, wage increases, and tax reforms, to increase consumer spending and redistribute income downward. Joint public-private public works projects helped reduce unemployment. Much of

1558-419: A week at the absolute reference point calibration measurements are performed. Example magnetic observatories include: Example seismic observation projects and observatories include: Example gravitational wave observatories include: A volcano observatory is an institution that conducts the monitoring of a volcano as well as research in order to understand the potential impacts of active volcanism. Among

1640-515: Is Santiago , and the national language is Spanish . Spain conquered and colonized the region in the mid-16th century, replacing Inca rule , but failed to conquer the independent Mapuche people who inhabited what is now south-central Chile. Chile emerged as a relatively stable authoritarian republic in the 1830s after their 1818 declaration of independence from Spain . During the 19th century, Chile experienced significant economic and territorial growth, putting an end to Mapuche resistance in

1722-833: Is a facility which precisely measures the total intensity of Earth's magnetic field for field strength and direction at standard intervals. Geomagnetic observatories are most useful when located away from human activities to avoid disturbances of anthropogenic origin, and the observation data is collected at a fixed location continuously for decades. Magnetic observations are aggregated, processed, quality checked and made public through data centers such as INTERMAGNET . The types of measuring equipment at an observatory may include magnetometers (torsion, declination-inclination fluxgate, proton precession, Overhauser-effect), variometer (3-component vector, total-field scalar), dip circle , inclinometer , earth inductor, theodolite , self-recording magnetograph, magnetic declinometer, azimuth compass.

1804-444: Is a scientific institution whose main task is to make observations in the fields of meteorology, geomagnetism and tides that are important for the navy and civil shipping. An astronomical observatory is usually also attached. Some of these observatories also deal with nautical weather forecasts and storm warnings, astronomical time services, nautical calendars and seismology. Example marine observatories include: A magnetic observatory

1886-430: Is now Chile. The next Europeans to reach Chile were Diego de Almagro and his band of Spanish conquistadors , who came from Peru in 1535 seeking gold. The Spanish encountered various cultures that supported themselves principally through slash-and-burn agriculture and hunting. The conquest of Chile began in earnest in 1540 and was carried out by Pedro de Valdivia , one of Francisco Pizarro 's lieutenants, who founded

1968-676: Is present-day Chile. Settlement sites from very early human habitation include Monte Verde, Cueva del Milodón and the Pali-Aike Crater 's lava tube . The Incas briefly extended their empire into what is now northern Chile, but the Mapuche (or Araucanians as they were known by the Spaniards) successfully resisted many attempts by the Inca Empire to subjugate them, despite their lack of state organization. They fought against

2050-619: Is suspended under the terms of the Antarctic Treaty , of which Chile is a signatory. It is the world's southernmost country that is geographically on the mainland. Chile controls Easter Island and Sala y Gómez Island, the easternmost islands of Polynesia, which it incorporated to its territory in 1888, and the Juan Fernández Islands , more than 600 km (370 mi) from the mainland. Also controlled but only temporarily inhabited (by some local fishermen) are

2132-658: Is that, because of their location above the Earth's atmosphere, their images are free from the effects of atmospheric turbulence that plague ground-based observations. As a result, the angular resolution of space telescopes such as the Hubble Space Telescope is often much smaller than a ground-based telescope with a similar aperture . However, all these advantages do come with a price. Space telescopes are much more expensive to build than ground-based telescopes. Due to their location, space telescopes are also extremely difficult to maintain. The Hubble Space Telescope

2214-613: Is the Mauna Kea Observatory , located near the summit of a 4,205 m (13,796 ft) volcano in Hawaiʻi. The Chacaltaya Astrophysical Observatory in Bolivia, at 5,230 m (17,160 ft), was the world's highest permanent astronomical observatory from the time of its construction during the 1940s until 2009. It has now been surpassed by the new University of Tokyo Atacama Observatory , an optical-infrared telescope on

2296-405: Is unique within this group in its narrowness from east to west, with the other long north–south countries (including Brazil, Russia, Canada, and the United States, among others) all being wider from east to west by a factor of more than 10. Chile also claims 1,250,000 km (480,000 sq mi) of Antarctica as part of its territory ( Chilean Antarctic Territory ). However, this latter claim

2378-512: The Maule river in 1812, but did not include the indigenous population or the inhabitants of the province of Chiloé. The population is estimated at 210,567, 86.1% of whom were Spanish or of European descent, 10% of whom were indigenous and 3.7% of whom were mestizos, blacks and mulattos . A 2021 study by Baten and Llorca-Jaña shows that regions with a relatively high share of North European migrants developed faster in terms of numeracy , even if

2460-717: The Pacific Alliance , and joined the OECD in 2010. There are various theories about the origin of the word Chile . According to 17th-century Spanish chronicler Diego de Rosales , the Incas called the valley of the Aconcagua Chili by corruption of the name of a Picunche tribal chief ( cacique ) called Tili , who ruled the area at the time of the Incan conquest in the 15th century. Another theory points to

2542-606: The Republic of Chile , is a country in western South America . It is the southernmost country in the world and the closest to Antarctica , stretching along a narrow strip of land between the Andes Mountains and the Pacific Ocean . Chile had a population of 17.5 million as of the latest census in 2017 and has a territorial area of 756,102 square kilometers (291,933 sq mi), sharing borders with Peru to

High-altitude balloons for X-ray astronomy have been used in a variety of countries. Example underground, underwater or under ice neutrino observatories include: Example meteorological observatories include: A marine observatory

2706-640: The constitutional referendum , which was put forward by the left-leaning Constitutional Convention . On 17 December 2023, voters rejected a second new constitution proposal in a new constitutional referendum , written by the conservative-led Constitutional Council . A long and narrow coastal Southern Cone country on the west side of the Andes Mountains , Chile stretches over 4,300 km (2,670 mi) north to south, but only 350 km (217 mi) at its widest point east to west and 64 km (40 mi) at its narrowest point east to west, with an average width of 175 km (109 mi). This encompasses

2788-502: The 1880s and gaining its current northern territory in the War of the Pacific (1879–83) by defeating Peru and Bolivia. In the 20th century, up until the 1970s, Chile underwent a process of democratization and experienced rapid population growth and urbanization , while relying increasingly on exports from copper mining to support its economy . During the 1960s and 1970s, the country

2870-547: The December 2017 presidential election . On 27 February 2010, Chile was struck by an 8.8 M w earthquake , the fifth largest ever recorded at the time. More than 500 people died (most from the ensuing tsunami ) and over a million people lost their homes. The earthquake was also followed by multiple aftershocks. Initial damage estimates were in the range of US$ 15–30 billion, around 10% to 15% of Chile's real gross domestic product. Chile achieved global recognition for

2952-513: The Earth". Another origin attributed to chilli is the onomatopoeic cheele-cheele —the Mapuche imitation of the warble of a bird locally known as trile . The Spanish conquistadors heard about this name from the Incas, and the few survivors of Diego de Almagro 's first Spanish expedition south from Peru in 1535–36 called themselves the "men of Chilli". Ultimately, Almagro is credited with

3034-602: The NRAO's headquarters until 1966, after which the facility was known as the National Radio Astronomy Observatory, Green Bank. In October 2016, the observatory became an independent institution following a 2012 recommendation that the NSF fully divest itself from the facility by October 1, 2016. Green Bank Observatory subsequently retained partial NSF funding, established private contracts, and formed

3116-827: The Popular Unity platform also called for nationalization of Chile's major copper mines in the form of a constitutional amendment. The measure was passed unanimously by Congress. As a result, the Richard Nixon administration organized and inserted secret operatives in Chile, in order to swiftly destabilize Allende's government. In addition, US financial pressure restricted international economic credit to Chile. The economic problems were also exacerbated by Allende's public spending, financed mostly through printing money, and by poor credit ratings given by commercial banks. Simultaneously, opposition media, politicians, business guilds and other organizations helped to accelerate

3198-704: The Sapa Inca Tupac Yupanqui and his army. The result of the bloody three-day confrontation known as the Battle of the Maule was that the Inca conquest of the territories of Chile ended at the Maule river . In 1520, while attempting to circumnavigate the globe, Ferdinand Magellan discovered the southern passage now named after him (the Strait of Magellan ) thus becoming the first European to set foot on what

3280-533: The Spanish monarchy (in memory of this day, Chile celebrates its National Day on 18 September each year). After these events, a movement for total independence, under the command of José Miguel Carrera (one of the most renowned patriots) and his two brothers Juan José and Luis Carrera , soon gained a wider following. Spanish attempts to re-impose arbitrary rule during what was called the Reconquista led to

3362-631: The US, Roque de los Muchachos Observatory in Spain, and Paranal Observatory and Cerro Tololo Inter-American Observatory in Chile . Specific research study performed in 2009 shows that the best possible location for ground-based observatory on Earth is Ridge A  — a place in the central part of Eastern Antarctica. This location provides the least atmospheric disturbances and best visibility. Beginning in 1933, radio telescopes have been built for use in

3444-717: The War of the Pacific, Chile became a Naval Power in the Americas, even sending a ship in protests in the Panama crisis of 1885 against the United States intervention in the then Colombian territory. The United States and Chile had the Baltimore crisis which almost became a war as Chile was a potential threat to the intentions of hegemony from the United States in the Western Hemisphere. In 1902 Chile and Argentina received

3526-470: The armed forces bombarded the presidential palace , Allende apparently committed suicide. After the coup, Henry Kissinger told U.S. president Richard Nixon that the United States had "helped" the coup. In 1970, when Allende was first elected, Henry Kissinger had stated "I don't see why we need to stand by and watch a country go Communist due to the irresponsibility of its own people". A military junta, led by General Augusto Pinochet , took control of

3608-626: The banking sector was nationalized . Many enterprises within the copper , coal, iron, nitrate , and steel industries were expropriated , nationalized, or subjected to state intervention. Industrial output increased sharply and unemployment fell during the Allende administration's first year. Allende's program included advancement of workers' interests, replacing the judicial system with "socialist legality", nationalization of banks and forcing others to bankruptcy, and strengthening "popular militias" known as MIR. Started under former President Frei,

3690-866: The best known are the Hawaiian Volcano Observatory and the Vesuvius Observatory . Mobile volcano observatories exist with the USGS VDAP (Volcano Disaster Assistance Program), to be deployed on demand. Each volcano observatory has a geographic area of responsibility it is assigned to whereby the observatory is tasked with spreading activity forecasts, analyzing potential volcanic activity threats and cooperating with communities in preparation for volcanic eruption . Chile Chile ( / ˈ tʃ ɪ l i / CHIL -ee or / ˈ tʃ ɪ l eɪ / CHIL -ay , Spanish: [ˈtʃile] ), officially

3772-555: The candidate of a coalition of 17 political parties called the Concertación , received an absolute majority of votes (55%). President Aylwin served from 1990 to 1994, in what was considered a transition period. In December 1993, Christian Democrat Eduardo Frei Ruiz-Tagle , the son of previous president Eduardo Frei Montalva, led the Concertación coalition to victory with an absolute majority of votes (58%). Frei Ruiz-Tagle

3854-576: The city of Santiago on 12 February 1541. Although the Spanish did not find the extensive gold and silver they sought, they recognized the agricultural potential of Chile's central valley, and Chile became part of the Spanish Empire . Conquest took place gradually, and the Europeans suffered repeated setbacks. A massive Mapuche insurrection that began in 1553 resulted in Valdivia's death and

3936-512: The colony in addition to the Mapuche, as was shown by Sir Francis Drake 's 1578 raid on Valparaíso, the colony's principal port. Chile hosted one of the largest standing armies in the Americas, making it one of the most militarized of the Spanish possessions, as well as a drain on the treasury of the Viceroyalty of Peru . The first general census was conducted by the government of Agustín de Jáuregui between 1777 and 1778; it indicated that

4018-775: The command of John Williams Wilson , the Magallanes Region started to be controlled by country in 1843 , while the Antofagasta Region , at the time in dispute with Bolivia , began to fill with people. After the Chilean Civil War of 1829–1830 in which the conservatives won, under the Joaquín Prieto Administration, the Chilean Constitution of 1833 was written and put into effect with high influence from

4100-408: The country to renounce to its claims in the rest of East Patagonia after a dispute that started in 1842 . As a result of the War of the Pacific with Peru and Bolivia (1879–83), Chile expanded its territory northward by almost one-third, eliminating Bolivia's access to the Pacific, and acquired valuable nitrate deposits, the exploitation of which led to an era of national affluence. Chile had joined

4182-802: The country, several hundred committed Chilean revolutionaries joined the Sandinista army in Nicaragua , guerrilla forces in Argentina or training camps in Cuba , Eastern Europe and Northern Africa. In the late 1980s, largely as a result of events such as the 1982 economic collapse and mass civil resistance in 1983–88, the government gradually permitted greater freedom of assembly, speech , and association, to include trade union and political activity. The government launched market-oriented reforms with Hernán Büchi as Minister of Finance. Chile moved toward

4264-628: The country. The years of the regime were marked by human rights violations . Chile actively participated in Operation Condor . In October 1973, at least 72 people were murdered by the Caravan of Death . According to the Rettig Report and Valech Commission , at least 2,115 were killed, and at least 27,265 were tortured (including 88 children younger than 12 years old). In 2011, Chile recognized an additional 9,800 victims, bringing

4346-520: The destruction of many of the colony's principal settlements. Subsequent major insurrections took place in 1598 and in 1655. Each time the Mapuche and other native groups revolted, the southern border of the colony was driven northward. The abolition of slavery by the Spanish crown in 1683 was done in recognition that enslaving the Mapuche intensified resistance rather than cowing them into submission. Despite royal prohibitions, relations remained strained from continual colonialist interference. Cut off to

4428-415: The discovery of silver ore in Chañarcillo, and the growing trade of the port of Valparaíso, which led to conflict over maritime supremacy in the Pacific with Peru. At the same time, attempts were made to strengthen sovereignty in southern Chile intensifying penetration into Araucanía and colonizing Llanquihue with German immigrants in 1848. Through the founding of Fort Bulnes by the Schooner Ancud under

4510-463: The electromagnetic spectrum that cannot penetrate the Earth's atmosphere and are thus impossible to observe using ground-based telescopes. The Earth's atmosphere is opaque to ultraviolet radiation, X-rays , and gamma rays and is partially opaque to infrared radiation so observations in these portions of the electromagnetic spectrum are best carried out from a location above the atmosphere of our planet. Another advantage of space-based telescopes

4592-405: The end of his term, Frei had not fully achieved his party's ambitious goals. In the 1970 election, Senator Salvador Allende of the Socialist Party of Chile (then part of the " Popular Unity " coalition which included the Communists, Radicals, Social-Democrats, dissident Christian Democrats, the Popular Unitary Action Movement, and the Independent Popular Action), achieved a partial majority in

4674-406: The entire upper portion of the telescope dome can be rotated to allow the instrument to observe different sections of the night sky. Radio telescopes usually do not have domes. For optical telescopes, most ground-based observatories are located far from major centers of population, to avoid the effects of light pollution . The ideal locations for modern observatories are sites that have dark skies,

4756-420: The essence of the stratified colonial social structure, which was greatly influenced by family politics and the Roman Catholic Church . A strong presidency eventually emerged, but wealthy landowners remained powerful. Bernardo O'Higgins once planned to expand Chile by liberating the Philippines from Spain and incorporating the islands. In this regard he tasked the Scottish naval officer, Lord Thomas Cochrane, in

4838-614: The field of radio astronomy to observe the Universe in the radio portion of the electromagnetic spectrum. Such an instrument, or collection of instruments, with supporting facilities such as control centres, visitor housing, data reduction centers, and/or maintenance facilities are called radio observatories . Radio observatories are similarly located far from major population centers to avoid electromagnetic interference (EMI) from radio , TV , radar , and other EMI emitting devices, but unlike optical observatories, radio observatories can be placed in valleys for further EMI shielding. Some of

4920-419: The first rightist President in 20 years, defeating former President Eduardo Frei Ruiz-Tagle of the Concertación , for a four-year term succeeding Bachelet. Due to term limits, Sebastián Piñera did not stand for re-election in 2013, and his term expired in March 2014 resulting in Michelle Bachelet returning to office. Sebastián Piñera succeeded Bachelet again in 2018 as the President of Chile after winning

5002-440: The north by desert, to the south by the Mapuche, to the east by the Andes Mountains, and to the west by the ocean, Chile became one of the most centralized, homogeneous territories in Spanish America. Serving as a sort of frontier garrison , the colony found itself with the mission of forestalling encroachment by both the Mapuche and Spain's European enemies, especially the English and the Dutch . Buccaneers and pirates menaced

The country also controls several Pacific islands, including Juan Fernández , Isla Salas y Gómez , Desventuradas , and Easter Island , and claims about 1,250,000 square kilometers (480,000 sq mi) of Antarctica as the Chilean Antarctic Territory . The capital and largest city of Chile

5166-433: The overall number of migrants was small. This effect might be related to externalities : the surrounding population adopted a similar behavior as the small non-European immigrant group, and new schools were created. Ironically, there might have been positive spillover effects from the educational investment made by migrants, at the same time numeracy might have been reduced by the greater inequality in these regions. However,

5248-402: The population consisted of 259,646 inhabitants: 73.5% of European descent , 7.9% mestizos , 8.6% indigenous peoples and 9.8% blacks. Francisco Hurtado, Governor of the province of Chiloé , conducted a census in 1784 and found the population consisted of 26,703 inhabitants, 64.4% of whom were whites and 33.5% of whom were natives. The Diocese of Concepción conducted a census in areas south of

5330-401: The positive effects of immigration were apparently stronger. In 1808, Napoleon's enthronement of his brother Joseph as the Spanish King precipitated the drive by Chile for independence from Spain . A national junta in the name of Ferdinand – heir to the deposed king – was formed on 18 September 1810. The Government Junta of Chile proclaimed an autonomous government for Chile within

5412-445: The result from the arbitral award of the Andes resolved by the British Crown . In 1903 the Puna de Atacama dispute was solved. In 1904 Chile and Bolivia signed a Treaty of Peace and Friendship which clarified the border between both countries. The Chilean economy partially degenerated into a system protecting the interests of a ruling oligarchy . By the 1920s, the emerging middle and working classes were powerful enough to elect

5494-445: The similarity of the valley of the Aconcagua with that of the Casma Valley in Peru, where there was a town and valley named Chili . Other theories say Chile may derive its name from a Native American word meaning either 'ends of the earth' or 'sea gulls'; from the Mapuche word chilli , which may mean 'where the land ends'" or from the Quechua chiri , 'cold', or tchili , meaning either 'snow' or "the deepest point of

5576-419: The small islands of San Ambrosio and San Felix . These islands are notable because they extend Chile's claim to territorial waters out from its coast into the Pacific Ocean. The northern Atacama Desert contains great mineral wealth, primarily copper and nitrates . The relatively small Central Valley, which includes Santiago, dominates the country in terms of population and agricultural resources. This area

5658-424: The stand as one of the high-income countries in South America by 1870. On 9 September 1888, Chile took possession of Easter Island by the signing of a mutual will agreement with the local king, thanks to the efforts of the Bishop of Tahiti, Monsignor José María Verdier since the island was constantly attacked by slave merchants. The naval officer Policarpo Toro represented the Chilean Government and Atamu Tekena

5740-417: The successful rescue of 33 trapped miners in 2010. On 5 August 2010, the access tunnel collapsed at the San José copper and gold mine in the Atacama Desert near Copiapó in northern Chile, trapping 33 men 700 meters (2,300 ft) below ground. A rescue effort organized by the Chilean government located the miners 17 days later. All 33 men were brought to the surface two months later on 13 October 2010 over

5822-414: The surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum . Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during observing, and closed when the telescope is not in use. In most cases,
