Question: Context: A farm is an area of land that is devoted primarily to agricultural processes with the primary objective of producing food and other crops; it is the basic facility in food production. The name is used for specialised units such as arable farms, vegetable farms, fruit farms, dairy, pig and poultry farms, and land used for the production of natural fibres, biofuel and other commodities. It includes ranches, feedlots, orchards, plantations and estates, smallholdings and hobby farms, and includes the farmhouse and agricultural buildings as well as the land. In modern times the term has been extended so as to include such industrial operations as wind farms and fish farms, both of which can operate on land or sea. , Oceania (or ), also known as Oceanica, is a region centred on the islands of the tropical Pacific Ocean. Opinions of what constitutes Oceania range from its three subregions of Melanesia, Micronesia, and Polynesia to, more broadly, the entire insular region between Southeast Asia and the Americas, including Australasia and the Malay Archipelago., <onlyinclude>
Agricultural science is a broad multidisciplinary field of biology that encompasses the parts of exact, natural, economic and social sciences that are used in the practice and understanding of agriculture. (Veterinary science, but not animal science, is often excluded from the definition.)</onlyinclude>, A biofuel is a fuel that is produced through contemporary biological processes, such as agriculture and anaerobic digestion, rather than a fuel produced by geological processes such as those involved in the formation of fossil fuels, such as coal and petroleum, from prehistoric biological matter. Biofuels can be derived directly from plants, or indirectly from agricultural, commercial, domestic, and/or industrial wastes. Renewable biofuels generally involve contemporary carbon fixation, such as those that occur in plants or microalgae through the process of photosynthesis. Other renewable biofuels are made through the use or conversion of biomass (referring to recently living organisms, most often referring to plants or plant-derived materials). This biomass can be converted to convenient energy-containing substances in three different ways: thermal conversion, chemical conversion, and biochemical conversion. This biomass conversion can result in fuel in solid, liquid, or gas form. This new biomass can also be used directly for biofuels., Bolivia (; ), officially known as the Plurinational State of Bolivia, is a landlocked country located in western-central South America. It is bordered to the north and east by Brazil, to the southeast by Paraguay, to the south by Argentina, to the southwest by Chile, and to the northwest by Peru. One-third of the country is the Andean mountain range, with one of its largest cities and principal economic centers, El Alto, located on the Altiplano. Bolivia is one of two landlocked countries (the other is Paraguay) that lie outside Afro-Eurasia. Bolivia is the largest landlocked country in the Americas., Culture can be defined in numerous ways. In the words of anthropologist E.B. Tylor, it is "that complex whole which includes knowledge, belief, art, morals, law, custom and any other capabilities and habits acquired by man as a member of society." Alternatively, in a contemporary variant, "Culture is defined as a social domain that emphasizes the practices, discourses and material expressions, which, over time, express the continuities and discontinuities of social meaning of a life held in common.", The Andes or Andean Mountains are the longest continental mountain range in the world. They are a continuous range of highlands along the western edge of South America. This range is about long, about wide (widest between 18° south and 20° south latitude), and of an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Argentina and Chile., Argentina, officially the Argentine Republic, is a federal republic in the southern half of South America. Sharing the bulk of the Southern Cone with its neighbor Chile to the west, the country is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. With a mainland area of , Argentina is the eighth-largest country in the world, the second largest in Latin America, and the largest Spanish-speaking one. The country is subdivided into twenty-three provinces (singular "provincia") and one autonomous city ("ciudad autónoma"), Buenos Aires, which is the federal capital of the nation as decided by Congress.
The provinces and the capital have their own constitutions, but exist under a federal system., Olivar is a commune in Chile , located in the O'Higgins Region , 10 km south of Rancagua , and administered by the municipality of Olivar . The main economic activities range from agriculture and food production , specially apples for exportation ., Fiber or fibre (from the Latin fibra) is a natural or synthetic substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene., South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It is also considered a subcontinent of the Americas, which is the model used in nations that speak Romance languages. The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil)., A breed is a specific group of domestic animals having homogeneous appearance (phenotype), homogeneous behavior, and/or other characteristics that distinguish it from other organisms of the same species. Breeds are formed through genetic isolation and either natural adaptation to the environment or selective breeding, or a combination of the two. Despite the centrality of the idea of "breeds" to animal husbandry and agriculture, no single, scientifically accepted definition of the term exists. A breed is therefore not an objective or biologically verifiable classification but is instead a term of art amongst groups of breeders who share a consensus around what qualities make some members of a given species members of a nameable subset., Easter Island is a Chilean island in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian Triangle. Easter Island is famous for its 887 extant monumental statues, called "moai", created by the early Rapa Nui people. In 1995, UNESCO named Easter Island a World Heritage Site, with much of the island protected within Rapa Nui National Park., Rancagua is a city and commune in central Chile and part of the Rancagua conurbation. It is the capital of the Cachapoal Province and of the O'Higgins Region, located south of the national capital of Santiago., Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the Cretaceous period, about 99 million years ago and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists., Chile, officially the Republic of Chile, is a South American country occupying a long, narrow strip of land between the Andes to the east and the Pacific Ocean to the west. It borders Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage in the far south. Chilean territory includes the Pacific islands of Juan Fernández, Salas y Gómez, Desventuradas, and Easter Island in Oceania. Chile also claims about of Antarctica, although all claims are suspended under the Antarctic Treaty., Rancagua conurbation, or Greater Rancagua, is a Chilean conurbation in the O'Higgins Region composed of Rancagua and some parts of Machalí and Gultro. It has an estimated population of 307,004 inhabitants for 2008. Several villages are expected to join the conurbation in a near future, like Olivar Bajo (Olivar), Punta de Cortés (Rancagua) and La Compañia (Graneros)., Antarctica (US English , UK English or ) is Earth's southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At , it is the fifth-largest continent. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula., Medicinal plants have been identified and used throughout human history. Plants make many chemical compounds that are for biological functions, including defence against insects, fungi and herbivorous mammals. At least 12,000 such compounds have been isolated so far; a number estimated to be less than 10% of the total. Chemical compounds in plants mediate their effect on the human body through processes identical to those already well understood for the chemical compounds in conventional drugs; thus herbal medicines do not differ greatly from conventional drugs in terms of how they work. This enables herbal medicines to have beneficial pharmacology, but also gives them the same potential as conventional pharmaceutical drugs to cause harmful side effects. Moreover, plant material comes with a variety of compounds which may have undesired effects, though these can be reduced by processing., Animals are multicellular, eukaryotic organisms of the kingdom Animalia (also called Metazoa). The animal kingdom emerged as a basal clade within Apoikozoa as a sister of the choanoflagellates. Sponges are the most basal clade of animals. Animals are motile, meaning they can move spontaneously and independently at some point in their lives. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later in their lives. All animals are heterotrophs: they must ingest other organisms or their products for sustenance., The history of agriculture records the domestication of plants and animals and the development and dissemination of techniques for raising them productively. Agriculture began independently in different parts of the globe, and included a diverse range of taxa. At least 11 separate regions of the Old and New World were involved as independent centers of origin., Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells to provide energy, maintain life, or stimulate growth., The Drake Passage or Mar de HocesSea of Hocesis the body of water between South America's Cape Horn and the South Shetland Islands of Antarctica. It connects the southwestern part of the Atlantic Ocean (Scotia Sea) with the southeastern part of the Pacific Ocean and extends into the Southern Ocean., Agriculture is the cultivation and breeding of animals, plants and fungi for food, fiber, biofuel, medicinal plants and other products used to sustain and enhance human life. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. The study of agriculture is known as agricultural science. The history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies. Industrial agriculture based on large-scale monoculture farming has become the dominant agricultural methodology., Santiago de Chile is the capital and largest city of Chile. It is also the center of its largest conurbation. Santiago is located in the country's central valley, at an elevation of above mean sea level., The Pacific Ocean is the largest of the Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south and is bounded by Asia and Australia in the west and the Americas in the east., Cachapoal Province is one of three provinces of the central Chilean region of O'Higgins (VI). Its capital is the city of Rancagua (pop. 214,344)., Monoculture is the agricultural practice of producing or growing a single crop, plant, or livestock species, variety, or breed in a field or farming system at a time. Polyculture, where more than one crop is grown in the same space at the same time, is the alternative to monoculture. Monoculture is widely used in both industrial farming and organic farming and has allowed increased efficiency in planting and harvest. , Peru , officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the west by the Pacific Ocean. Peru is an extremely biodiverse country with habitats ranging from the arid plains of the Pacific coastal region in the west to the peaks of the Andes mountains vertically extending from the north to the southeast of the country to the tropical Amazon Basin rainforest in the east with the Amazon river., Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae., Climate is the statistics of weather, usually over a 30-year interval. It is measured by assessing the patterns of variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time. Climate differs from weather, in that weather only describes the short-term conditions of these variables in a given region., A fuel is any material that can be made to react with other substances so that it releases chemical or nuclear energy as heat or to be used for work. The concept was originally applied solely to those materials capable of releasing chemical energy but has since also been applied to other sources of heat energy such as nuclear energy (via nuclear fission and nuclear fusion)., A civilization, or civilisation (see spelling differences), is any complex society characterized by urban development, social stratification, symbolic communication forms (typically, writing systems), and a perceived separation from and domination over the natural environment by a cultural elite. Civilizations are intimately associated with and often further defined by other socio-politico-economic characteristics, including centralization, the domestication of both humans and other organisms, specialization of labour, culturally ingrained ideologies of progress and supremacism, monumental architecture, taxation, societal dependence upon farming as an agricultural practice, and expansionism., The VI Libertador General Bernardo O'Higgins Region, often shortened to O'Higgins Region, is one of Chile's 15 first order administrative divisions. It is subdivided into three provinces. It is named in honour of Bernardo O'Higgins Riquelme, one of Chile's founding fathers., Subject: olivar, Relation: located_in_the_administrative_territorial_entity, Options: (A) antarctica (B) argentina (C) atlantic ocean (D) bolivia (E) brazil (F) breed (G) cachapoal province (H) center (I) central (J) chile (K) colombia (L) earth (M) insular region (N) most (O) mountain (P) north (Q) northern (R) northwest (S) of (T) pacific ocean (U) paraguay (V) peru (W) rancagua (X) rapa (Y) river (Z) santiago ([) shetland (\) south (]) time

Answer: cachapoal province


Question: Context: Wigtown Burghs , also known as Wigton Burghs , . was a constituency of the House of Commons of the Parliament of Great Britain from 1708 to 1800 and of the House of Commons of the Parliament of the United Kingdom from 1801 to 1885 . It was represented by one Member of Parliament ( MP ) . The first election in Wigtown Burghs was in 1708 . In 1707 -- 08 , members of the 1702 -- 1707 Parliament of Scotland were co-opted to serve in the 1st Parliament of Great Britain . See Scottish representatives to the 1st Parliament of Great Britain , for further details ., In modern politics and history, a parliament is a legislative, elected body of government. Generally a modern parliament has three functions: representing the electorate, making laws, and overseeing the government ("i.e.", hearings, inquiries)., A burgh was an autonomous corporate entity in Scotland and Northern England, usually a town, or toun in Scots. This type of administrative division existed from the 12th century, when King David I created the first royal burghs. Burgh status was broadly analogous to borough status, found in the rest of the United Kingdom. Following local government reorganization in 1975 the title of "royal burgh" remains in use in many towns, but now has little more than ceremonial value., Wigtownshire or the County of Wigtown is a registration county and lieutenancy area in south-west Scotland. Until 1975, Wigtownshire was one of the administrative counties used for local government purposes, and is now administered as part of the council area of Dumfries and Galloway. As a lieutenancy area, Wigtownshire has its own Lord Lieutenant, currently John Alexander Ross., Newton Stewart (Gd: "Baile Ùr nan Stiùbhartach") is a former burgh town in Dumfries and Galloway, southwest Scotland.
The town is on the River Cree with most of the town to the west of the river, and is sometimes referred to as the "Gateway to the Galloway Hills". Newton Stewart has also recently been twinned with the French town of Marcoussis., The Kingdom of Great Britain, officially Great Britain , was a sovereign state in western Europe from 1 May 1707 to 31 December 1800. The state came into being following the Treaty of Union in 1706, ratified by the Acts of Union 1707, which united the kingdoms of England and Scotland to form a single kingdom encompassing the whole island of Great Britain and its outlying islands. It did not include Ireland, which remained a separate realm. The unitary state was governed by a single parliament and government that was based in Westminster. The former kingdoms had been in personal union since James VI, King of Scots, became King of England and King of Ireland in 1603 following the death of Queen Elizabeth I, bringing about a "Union of the Crowns". Also after the accession of George I to the throne of Great Britain in 1714, the kingdom was in a personal union with the Electorate of Hanover., The Parliament of England was the legislature of the Kingdom of England. In 1066, William of Normandy introduced what, in later centuries, became referred to as a feudal system, by which he sought the advice of a council of tenants-in-chief (a person who held land) and ecclesiastics before making laws. In 1215, the tenants-in-chief secured Magna Carta from King John, which established that the king may not levy or collect any taxes (except the feudal taxes to which they were hitherto accustomed), save with the consent of his royal council, which gradually developed into a parliament., The Parliament of Great Britain was formed in 1707 following the ratification of the Acts of Union by both the Parliament of England and the Parliament of Scotland. The Acts created a new unified Kingdom of Great Britain and dissolved the separate English and Scottish parliaments in favour of a single parliament, located in the former home of the English parliament in the Palace of Westminster, near the City of London. This lasted nearly a century, until the Acts of Union 1800 merged the separate British and Irish Parliaments into a single Parliament of the United Kingdom with effect from 1 January 1801., Stranraer is a town in Inch, Wigtownshire, in the west of Dumfries and Galloway, southwest Scotland. It lies on the shores of Loch Ryan, on the northern side of the isthmus joining the Rhins of Galloway to the mainland. Stranraer is Dumfries and Galloway's second-largest town, with a population including the surrounding area of nearly 13,000., The Parliament of the United Kingdom, commonly known as the UK Parliament or British Parliament, is the supreme legislative body in the United Kingdom, British Crown dependencies and British overseas territories. It alone possesses legislative supremacy and thereby ultimate power over all other political bodies in the UK and its territories. Its head is the Sovereign of the United Kingdom (currently Queen Elizabeth II) and its seat is the Palace of Westminster in the City of Westminster, London., Dumfries (; possibly from ) is a market town and former royal burgh within the Dumfries and Galloway council area of Scotland. It is near the mouth of the River Nith into the Solway Firth. Dumfries was a civil parish and became the county town of the former county of Dumfriesshire. Dumfries is nicknamed "Queen of the South". People from Dumfries are known colloquially as "Doonhamers"., The Palace of Westminster is the meeting place of the House of Commons and the House of Lords, the two houses of the Parliament of the United Kingdom. Commonly known as the Houses of Parliament after its occupants, it is also known as the 'heart of British politics'. The Palace lies on the north bank of the River Thames in the City of Westminster, in central London., A Member of Parliament (MP) is the 
representative of the voters to a parliament. In many countries with bicameral parliaments, this category includes specifically members of the lower house, as upper houses often have a different title., Dumfries and Galloway is one of 32 unitary council areas of Scotland and is located in the western Southern Uplands. It comprises the historic counties of Dumfriesshire, Stewartry of Kirkcudbright and Wigtownshire, the latter two of which are collectively known as Galloway. The administrative centre is the town of Dumfries., Wigtown is a town and former royal burgh in Wigtownshire, of which it is the county town, within the Dumfries and Galloway region in Scotland. It lies east of Stranraer and south of Newton Stewart. It is well known today as "Scotland's National Book Town" with a high concentration of second-hand book shops. It has a population of about 1,000., The Acts of Union 1800 (sometimes erroneously referred to as a single Act of Union 1801) united the Kingdom of Great Britain and the Kingdom of Ireland (previously in personal union) to create the United Kingdom of Great Britain and Ireland with effect from 1 January 1801. Both Acts, though since amended, still remain in force in the United Kingdom, but have been repealed in the Republic of Ireland., The City of Westminster is an Inner London borough which also holds city status. It occupies much of the central area of Greater London including most of the West End. It is to the west of and adjoining the ancient City of London, directly to the east of the Royal Borough of Kensington and Chelsea, and its southern boundary is the River Thames. It was created with the 1965 establishment of Greater London. Upon creation, Westminster was awarded city status, which had been previously held by the smaller Metropolitan Borough of Westminster., Scotland (Scots: ) is a country that is part of the United Kingdom and covers the northern third of the island of Great Britain. It shares a border with England to the south, and is otherwise surrounded by the Atlantic Ocean, with the North Sea to the east and the North Channel and Irish Sea to the south-west. In addition to the mainland, the country is made up of more than 790 islands, including the Northern Isles and the Hebrides., The City of London is a city and county within London. It constituted most of London from its settlement by the Romans in the 1st century AD to the Middle Ages, but the agglomeration has since grown far beyond the City's borders. The City is now only a tiny part of the metropolis of London, though it remains a notable part of central London. Administratively, it forms one of the 33 local authority districts of Greater London; however, the City of London is not a London borough, a status reserved for the other 32 districts (including London's only other city, the City of Westminster). , A royal burgh was a type of Scottish burgh which had been founded by, or subsequently granted, a royal charter. Although abolished in law in 1975, the term is still used by many former royal burghs., The 14 British Overseas Territories (BOT) are territories under the jurisdiction and sovereignty of the United Kingdom. They are those parts of the former British Empire that have not chosen independence or have voted to remain British territories. Most of the inhabited territories are internally self-governing, with the UK retaining responsibility for defence and foreign relations. The rest are either uninhabited or have a transitory population of military or scientific personnel. They share the British monarch (Elizabeth II) as head of state., The Parliament of Scotland, officially the Estates of Parliament, was the legislature of the Kingdom of Scotland. The parliament, like other such institutions, evolved during the Middle Ages from the king's council of bishops and earls. It is first identifiable as a parliament in 1235, during the reign of Alexander II, when it was described as a "colloquium" and already possessed a political and judicial role. By the early fourteenth century, the attendance of knights and freeholders had become important, and from 1326 commissioners from the burghs attended. Consisting of the "three estates" of clergy, nobility and the burghs sitting in a single chamber, the parliament gave consent for the raising of taxation and played an important role in the administration of justice, foreign policy, war, and all manner of other legislation. Parliamentary business was also carried out by "sister" institutions, such as General Councils or Convention of Estates. These could carry out much business also dealt with by parliament  taxation, legislation and policy-making  but lacked the ultimate authority of a full parliament., Subject: wigtown burghs , Relation: located_in_the_administrative_territorial_entity, Options: (A) atlantic ocean (B) centre (C) city of westminster (D) dumfries (E) dumfries and galloway (F) elizabeth (G) england (H) europe (I) galloway (J) greater london (K) hanover (L) ireland (M) kensington (N) king (O) kingdom of great britain (P) london (Q) most (R) nan (S) newton (T) northern (U) of (V) river (W) royal borough of kensington and chelsea (X) scotland (Y) south (Z) stranraer ([) united kingdom (\) united kingdom of great britain and ireland (]) west (^) westminster

Question: Context: A planetary nebula, often abbreviated as PN or plural PNe, is a kind of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from old red giant stars late in their lives. The word "nebula" is Latin for mist or cloud, and the term "planetary nebula" is a misnomer that originated in the 1780s with astronomer William Herschel because when viewed through his telescope, these objects resemble the rounded shapes of planets. Herschel's name for these objects was popularly adopted and has not been changed. They are a relatively short-lived phenomenon, lasting a few tens of thousands of years, compared to a typical stellar lifetime of several billion years., A supernova remnant (SNR) is the structure resulting from the explosion of a star in a supernova. The supernova remnant is bounded by an expanding shock wave, and consists of ejected material expanding from the explosion, and the interstellar material it sweeps up and shocks along the way., Scattering is a general physical process where some forms of radiation, such as light, sound, or moving particles, are forced to deviate from a straight trajectory by one or more paths due to localized non-uniformities in the medium through which they pass. In conventional use, this also includes deviation of reflected radiation from the angle predicted by the law of reflection. Reflections that undergo scattering are often called "diffuse reflections" and unscattered reflections are called "specular" (mirror-like) reflections. , Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets; while the phenomena include supernovae explosions, gamma ray bursts, and cosmic microwave background radiation. More generally, all astronomical phenomena that originate outside Earth's atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole., Orion's Belt or the Belt of Orion, also known as the Three Kings or Three Sisters, is an asterism in the constellation Orion. It consists of the three bright stars Alnitak, Alnilam and Mintaka., A star is a luminous sphere of plasma held together by its own gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye from Earth during the night, appearing as a multitude of fixed luminous points in the sky due to their immense distance from Earth. Historically, the most prominent stars were grouped into constellations and asterisms, the brightest of which gained proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. However, most of the stars in the Universe, including all stars outside our galaxy, the Milky Way, are invisible to the naked eye from Earth. Indeed, most are invisible from Earth even through the most powerful telescopes., Star formation is the process by which dense regions within molecular clouds in The "medium" is present further soon.-->interstellar space, sometimes referred to as "stellar nurseries" or "star-forming regions", fuse to form stars. As a branch of astronomy, star formation includes the study of the interstellar medium (ISM) and giant molecular clouds (GMC) as precursors to the star formation process, and the study of protostars and young stellar objects as its immediate products. It is closely related to planet formation, another branch of astronomy. Star formation theory, as well as accounting for the formation of a single star, must also account for the statistics of binary stars and the initial mass function., An emission nebula is a nebula formed of ionized gases that emit light of various colors. The most common source of ionization is high-energy photons emitted from a nearby hot star. Among the several different types of emission nebulae are H II regions, in which star formation is taking place and young, massive stars are the source of the ionizing photons; and planetary nebulae, in which a dying star has thrown off its outer layers, with the exposed hot core then ionizing them., The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process.<ref name="doi10.1146/annurev-astro-081913-040012"></ref> It is by far the most important source of energy for life on Earth. Its diameter is about 109 times that of Earth, and its mass is about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System.
About three quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron., Stewart Sharpless (March 29, 1926  January 19, 2013) was an American astronomer who carried out fundamental work on the structure of the Milky Way galaxy., The Sharpless catalog is a list of 313 HII regions (emission nebulae), intended to be comprehensive north of declination -27°. (It does include some nebulae south of that declination as well.) The first edition was published in 1953 with 142 objects (Sh1), and the second and final version was published by US astronomer Stewart Sharpless in 1959 with 312 objects. Sharpless also includes some planetary nebulae and supernova remnants, in addition to HII regions., Earth, otherwise known as the world, is the third planet from the Sun and the only object in the Universe known to harbor life. It is the densest planet in the Solar System and the largest of the four terrestrial planets., A constellation is formally defined as a region of the celestial sphere, with boundaries laid down by the International Astronomical Union (IAU). The constellation areas mostly had their origins in Western-traditional patterns of stars from which the constellations take their names., A nebula (Latin for "cloud"; pl. nebulae, nebulæ, or nebulas) is an interstellar cloud of dust, hydrogen, helium and other ionized gases. Originally, "nebula" was a name for any diffuse astronomical object, including galaxies beyond the Milky Way. The Andromeda Galaxy, for instance, was once referred to as the "Andromeda Nebula" (and spiral galaxies in general as "spiral nebulae") before the true nature of galaxies was confirmed in the early 20th century by Vesto Slipher, Edwin Hubble and others., NGC 1973/5/7 is a reflection nebula 1/2 degree northeast of the Orion Nebula . The three NGC objects are divided by darker regions . It is also called The Running Man Nebula and Sharpless Catalog 279 . This object was named ' The Running Man Nebula ' by Texas Astronomical Society member Jason Ware . Approximately 20 years ago his down stairs neighbor looked at the object and said it looked like a running man . He brought this up a TAS club meeting and the name stuck . Now widely accepted as ' The Running Man ' ., The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula., Naked eye, also called bare eye or unaided eye, is the practice of engaging in visual perception unaided by a magnifying or light-collecting optical device, such as a telescope or microscope. Vision corrected to normal acuity using corrective lenses is considered "naked". In astronomy, the naked eye may be used to observe events that can be viewed without equipment, such as an astronomical conjunction, the passage of a comet, or a meteor shower. Sky lore and various tests demonstrate an impressive wealth of phenomena that can be seen with the unaided eye., An ion is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge. Ions can be created, by either chemical or physical means, via ionization., The Milky Way is the galaxy that contains our Solar System. The descriptive "milky" is derived from the appearance from Earth of the galaxy  a band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The term "Milky Way" is a translation of the Latin ', from the Greek (', "milky circle"). From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis, observations by Edwin Hubble showed that the Milky Way is just one of many galaxies., In astronomy, reflection nebulae are clouds of interstellar dust which might reflect the light of a nearby star or stars. The energy from the nearby stars is insufficient to ionize the gas of the nebula to create an emission nebula, but is enough to give sufficient scattering to make the dust visible. Thus, the frequency spectrum shown by reflection nebulae is similar to that of the illuminating stars. Among the microscopic particles responsible for the scattering are carbon compounds (e. g. diamond dust) and compounds of other elements such as iron and nickel. The latter two are often aligned with the galactic magnetic field and cause the scattered light to be slightly polarized., Subject: ngc 1973, Relation: instance_of, Options: (A) addition (B) asterism (C) astronomical object (D) atmosphere (E) belt (F) catalog (G) charge (H) chemical (I) comet (J) constellation (K) debate (L) diamond (M) disk (N) distance (O) emission nebula (P) energy (Q) equipment (R) formation (S) four (T) galaxy (U) gas (V) giant (W) interstellar cloud (X) ion (Y) january (Z) magnetic field ([) march (\) material (]) may (^) meteor (_) meteor shower (`) microscope (a) mirror (b) molecule (c) motion (d) name (e) natural science (f) nebula (g) negative (h) perception (i) phenomenon (j) physics (k) planet (l) planetary nebula (m) practice (n) process (o) science (p) single (q) sound (r) sphere (s) star (t) supernova (u) supernova remnant (v) system (w) telescope (x) theory (y) three (z) vision
