Context: St Thomas' Hospital is a large NHS teaching hospital in Central London, England. It is one of the institutions that comprise the King's Health Partners, an academic health science centre. Administratively part of the Guy's and St Thomas' NHS Foundation Trust, together with Guy's Hospital and King's College Hospital it provides the location of the King's College London School of Medicine., Exeter College (in full: The Rector and Scholars of Exeter College in the University of Oxford) is one of the constituent colleges of the University of Oxford in England and the fourth oldest college of the University., King's College London (informally King's or KCL) is a public research university located in London, United Kingdom, and a founding constituent college of the federal University of London. King's was established in 1829 by King George IV and the Duke of Wellington and received its royal charter in the same year. In 1836, King's became one of the two founding colleges of the University of London. In the late 20th century, it grew through a series of mergers, including with Queen Elizabeth College and Chelsea College of Science and Technology (in 1985), the Institute of Psychiatry (in 1997), the United Medical and Dental Schools of Guy's and St Thomas' Hospitals and the Florence Nightingale School of Nursing and Midwifery (in 1998)., Sir Richard Hughes '' Rick '' Trainor KBE , FRHS , FKC FAcSS ( born 31 December 1948 ) , is an academic administrator and historian who served as the Principal of King 's College London from 2004 to 2014 . He was previously the Vice-Chancellor of the University of Greenwich from 2000 to 2004 . He is currently Rector of Exeter College , Oxford . Trainor was born in the United States . He was awarded an honorary knighthood ( KBE ) in June 2010 for services to higher education in the United Kingdom . The award was honorary because of his American nationality , but on 31 December 2010 the knighthood was made substantive by Queen Elizabeth II following his assumption of British nationality ., A royal charter is a formal document issued by a monarch as letters patent, granting a right or power to an individual or a body corporate. They were, and are still, used to establish significant organisations such as cities (with municipal charters) or universities and learned societies. Charters should be distinguished from warrants and letters of appointment, as they have perpetual effect. Typically, a Royal Charter is produced as a high-quality work of calligraphy on vellum. The British monarchy has issued over 980 royal charters. Of these about 750 remain in existence. The earliest was to the town of Tain in 1066, making it the oldest Royal Burgh in Scotland, followed by the University of Cambridge in 1231. Charters continue to be issued by the British Crown, a recent example being that awarded to the Chartered Institute for the Management of Sport and Physical Activity, on 7 April 2011., The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., Chelsea College of Science and Technology was established as a College of Advanced Technology on a single site on the corner of Manresa Road and King's Road, Chelsea, London SW3, as part of the University of London in 1966 and was granted its Royal Charter in 1971 at which time it was renamed Chelsea College. In 1985, it merged with King's College London., The University of Oxford (informally Oxford University or simply Oxford) is a collegiate research university located in Oxford, England, United Kingdom. While having no known date of foundation, there is evidence of teaching as far back as 1096, making it the oldest university in the English-speaking world and the world's second-oldest university in continuous operation. It grew rapidly from 1167 when Henry II banned English students from attending the University of Paris. After disputes between students and Oxford townsfolk in 1209, some academics fled northeast to Cambridge where they established what became the University of Cambridge. The two "ancient universities" are frequently jointly referred to as "Oxbridge"., London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly., The University of Greenwich is a British, United Kingdom-based university. It has three campuses in London and Kent, England. These are located at Greenwich, in the grounds of the Old Royal Naval College, and in Avery Hill and Medway., The United Medical and Dental Schools of Guy's and St Thomas' Hospitals was the name given to the joint medical and dental school formed in London as a result of the merger of Guy's Hospital Medical School, St Thomas's Hospital Medical School and the Royal Dental Hospital of London., The University of London is a collegiate research university located in London, England, consisting of 18 constituent colleges, nine research institutes and a number of central bodies., The Old Royal Naval College is the architectural centrepiece of Maritime Greenwich, a World Heritage Site in Greenwich, London, described by the United Nations Educational, Scientific and Cultural Organisation (UNESCO) as being of "outstanding universal value" and reckoned to be the "finest and most dramatically sited architectural and landscape ensemble in the British Isles". The site is managed by the Greenwich Foundation for the Old Royal Naval College (Foundation), set up in July 1998 as a Registered Charity to "look after these magnificent buildings and their grounds for the benefit of the nation". The grounds and some of its buildings are open to visitors. The buildings were originally constructed to serve as the Royal Hospital for Seamen at Greenwich, now generally known as Greenwich Hospital, which was designed by Christopher Wren, and built between 1696 and 1712. The hospital closed in 1869. Between 1873 and 1998 it was the Royal Naval College, Greenwich., Subject: rick trainor, Relation: employer, Options: (A) capital (B) rector (C) school (D) the atlantic (E) the nation (F) time (G) united nations (H) university of cambridge (I) university of greenwich (J) university of london (K) university of oxford

Context: Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries., Casino Stadion is a multi-use stadium in Bregenz , Austria . It is currently used mostly for football matches and is the home ground of SC Bregenz . The stadium holds 11,112 people ., Switzerland, officially the Swiss Confederation, is a federal republic in Europe. It consists of 26cantons, and the city of Bern is the seat of the federal authorities.
The country is situated in Western-Central Europe, and is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is a landlocked country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning an area of . While the Alps occupy the greater part of the territory, the Swiss population of approximately eight million people is concentrated mostly on the plateau, where the largest cities are to be found: among them are the two global cities and economic centres Zurich and Geneva., Lake Constance (German: Bodensee) is a lake on the Rhine at the northern foot of the Alps, and consists of three bodies of water: the "Obersee" ("upper lake"), the "Untersee" ("lower lake"), and a connecting stretch of the Rhine, called the "Seerhein"., A concert is a live music performance in front of an audience. A recital is a concert by a soloist or small group which follows a program, such as featuring the works of a single composer (organ recital). A recitalist is a musician who gives frequent recitals. The invention of the solo piano recital has been attributed to Franz Liszt., Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of , and has a largely temperate seasonal climate. With about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular immigration destination in the world. Germany's capital and largest metropolis is Berlin. Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart and Dusseldorf., The UEFA Intertoto Cup, also abbreviated as UI Cup and originally called the International Football Cup was a summer football competition for European clubs that had not qualified for one of the two major UEFA competitions, the Champions League and the UEFA Cup. The competition was discontinued after the 2008 tournament. Teams who originally would have entered the Intertoto Cup now directly enter the qualifying stages of the UEFA Europa League from this point., A stadium (plural stadiums or stadia) is a place or venue for (mostly) outdoor sports, concerts, or other events and consists of a field or stage either partly or completely surrounded by a tiered structure designed to allow spectators to stand or sit and view the event., Vorarlberg is the westernmost federal state ("Bundesland") of Austria. Although it has the second-smallest area (Vienna is the smallest) and population (Burgenland is less populated), it has the second-highest population density (after Vienna). It borders three countries: Germany (Bavaria and Baden-Wurttemberg via Lake Constance), Switzerland (Graubunden and St. Gallen) and Liechtenstein. The only Austrian state that shares a border with Vorarlberg is Tyrol to the east., Bregenz is the capital of Vorarlberg, the westernmost federal state of Austria. The city is located on the eastern shores of Lake Constance, the third-largest freshwater lake in Central Europe, between Switzerland in the west and Germany in the northwest., SC Bregenz is an Austrian association football club from Austria, based in the town of Bregenz, which was founded in 1919.

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, nebul, 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 24light 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
