Dorado
Dorado (, ) is a constellation in the Southern Sky. It was named in the late 16th century and is now one of the 88 modern constellations. Its name refers to the mahi-mahi (''Coryphaena hippurus''), which is known as ''dorado'' ("golden") in Spanish, although it has also been depicted as a swordfish. Dorado contains most of the Large Magellanic Cloud, the remainder being in the constellation Mensa. The South Ecliptic pole also lies within this constellation. Even though the name Dorado is not Latin but Spanish, astronomers give it the Latin genitive form ''Doradus'' when naming its stars; it is treated (like the adjacent asterism Argo Navis) as a feminine proper name of Greek origin ending in -ō (like ''Io'' or ''Callisto'' or ''Argo''), which have a genitive ending ''-ūs''. History Dorado was one of twelve constellations named by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman.

Mahi-mahi
The mahi-mahi ( ) or common dolphinfish (''Coryphaena hippurus'') is a surface-dwelling ray-finned fish found in off-shore temperate, tropical, and subtropical waters worldwide. It is also widely called dorado (not to be confused with '' Salminus brasiliensis'', a freshwater fish) and dolphin (not to be confused with the aquatic mammal dolphin). It is one of two members of the family Coryphaenidae, the other being the pompano dolphinfish. These fish are most commonly found in the waters around the Gulf of Mexico, Costa Rica, Hawaii, and the Indian Ocean. In Italy it is called corifena, lampuga or pesce capone, and has even given its name to the caponata though eggplant has now taken the place of the fish. Nomenclature The name ''mahi-mahi'' comes from the Hawaiian language and means 'very strong', through the process of reduplication. By chance in Persian, () means 'fish', but the word is Hawaiian. Though the species is also referred to as the common dolphinfish, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IAU Designated Constellations
In contemporary astronomy, 88 constellations are recognized by the International Astronomical Union (IAU). Each constellation is a region of the sky bordered by arcs of right ascension and declination, together covering the entire celestial sphere. Their boundaries were officially adopted by the International Astronomical Union in 1928 and published in 1930. The ancient Mesopotamians and later the Greeks established most of the northern constellations in international use today, listed by the Roman-Egyptian astronomer Ptolemy. The constellations along the ecliptic are called the zodiac. When explorers mapped the stars of the southern skies, European astronomers proposed new constellations for that region, as well as ones to fill gaps between the traditional constellations. Because of their Roman and European origins, every constellation has a Latin name. In 1922, the International Astronomical Union adopted three-letter abbreviations for 89 constellations, the modern list of 88 ...

Dolphinfish
''Coryphaena'' is a genus of marine ray-finned fishes known as the dolphinfishes, and is currently the only known genus in the family Coryphaenidae. The generic name is from Greek κορυφή (''koryphē'', "crown, top") and -αινα (-''aina'', feminine suffix). Species in this genus have compressed heads and single dorsal fins that run the entire length of the fishes' bodies. Dolphinfish are aggressive predatory fish that actively prey upon oceanic forage fishes, while in turn serving as a primary food source for many larger pelagic predators. The dolphinfish can reach up to about , and are some of the fastest-growing species in the ocean. Despite the name, dolphinfishes are unrelated to and look unlike dolphins (which are marine mammal Marine mammals are mammals that rely on marine ecosystems for their existence. They include animals such as cetaceans, pinnipeds, sirenians, sea otters and polar bears. They are an informal group, unified only by their reliance on mar ...

Swordfish
The swordfish (''Xiphias gladius''), also known as the broadbill in some countries, are large, highly migratory predatory fish characterized by a long, flat, pointed bill. They are the sole member of the Family (biology), family Xiphiidae. They are a popular sport fish of the billfish category. Swordfish are elongated, round-bodied, and lose all teeth and scales by adulthood. These fish are found widely in tropical and temperate parts of the Atlantic, Pacific, and Indian Oceans, and can typically be found from near the surface to a depth of , and exceptionally up to depths of 2,234 m. They commonly reach in length, and the maximum reported is in length and in weight. Taxonomy and etymology The swordfish is named after its long pointed, flat bill, which resembles a sword. The species name, ''Xiphias gladius'', derives from Greek Language, Greek (''xiphias'', "swordfish"), itself from (''xiphos'', "sword") and from Latin language, Latin ("sword").

Mensa (constellation)
Mensa is a constellation in the Southern Celestial Hemisphere near the south celestial pole, one of fourteen constellations drawn up in the 18th century by French astronomer Nicolas-Louis de Lacaille. Its name is Latin for table, though it originally commemorated Table Mountain and was known as "Mons Mensae". One of the IAU designated constellations, eighty-eight constellations designated by the International Astronomical Union (IAU), it covers a Keystone (architecture), keystone-shaped wedge of sky 153.5 square degrees in area. Other than the south polar constellation of Octans, it is the most southerly of constellations and is observable only south of the 5th parallel north, 5th parallel of the Northern hemisphere, Northern Hemisphere. One of the faintest constellations in the night sky, Mensa contains no apparently bright stars—the brightest, Alpha Mensae, is barely visible in suburban skies. Part of the Large Magellanic Cloud, several star clusters and a quasar lie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johannes Kepler
Johannes Kepler (27 December 1571 – 15 November 1630) was a German astronomer, mathematician, astrologer, Natural philosophy, natural philosopher and writer on music. He is a key figure in the 17th-century Scientific Revolution, best known for his Kepler's laws of planetary motion, laws of planetary motion, and his books ''Astronomia nova'', ''Harmonice Mundi'', and ''Epitome Astronomiae Copernicanae'', influencing among others Isaac Newton, providing one of the foundations for his theory of Newton's law of universal gravitation, universal gravitation. The variety and impact of his work made Kepler one of the founders and fathers of modern astronomy, the scientific method, Natural science, natural and modern science. He has been described as the "father of science fiction" for his novel ''Somnium (novel), Somnium''. Kepler was a mathematics teacher at a seminary school in Graz, where he became an associate of Hans Ulrich von Eggenberg, Prince Hans Ulrich von Eggenberg. Lat ...

Uranometria
is a star atlas produced by Johann Bayer. It was published in Augsburg in 1603 by Christoph Mang (''Christophorus Mangus'') under the full title (from Latin: ''Uranometria, containing charts of all the constellations, drawn by a new method and engraved on copper plates''). The word "uranometria", , literally translates to "measuring the heavens". It was the first atlas to cover the entire celestial sphere. Charts ''Uranometria'' contains 51 star charts, engraved on copper plates by Alexander Mair ( 1562–1617). The first 48 charts illustrate each of the 48 Ptolemaic constellations. The 49th chart introduces 12 new constellations in the deep southern sky, which was unknown to Ptolemy. The final two charts are planispheres labeled "''Synopsis coeli superioris borea''" and "''Synopsis coeli inferioris austrina''", or (roughly), "Overview of the northern celestial hemisphere" and "Overview of the southern celestial hemisphere". Each plate includes a grid for accurately deter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Bayer
Johann Bayer (; 1572 – 7 March 1625) was a German lawyer and uranographer (celestial cartographer). He was born in Rain in 1572. In 1592, aged 20, he began his study of philosophy and law at the University of Ingolstadt, after which he moved to Augsburg to begin work as a lawyer, becoming legal adviser to the city council in 1612. Bayer had several interests outside his work, including archaeology and mathematics. However, he is primarily known for his work in astronomy; particularly for his work on determining the positions of objects on the celestial sphere. He remained unmarried and died in 1625. Bayer's star atlas '' Uranometria Omnium Asterismorum'' (" Uranometry of all the asterisms") was first published in 1603 in Augsburg and dedicated to two prominent local citizens. This was the first atlas to cover the entire celestial sphere. It was based upon the work of Tycho Brahe and may have borrowed from Alessandro Piccolomini's 1540 star atlas, ''De le stelle fiss ...

Jodocus Hondius
Jodocus Hondius (Latinized version of his Dutch name: ''Joost de Hondt'') (17 October 1563 – 12 February 1612) was a Flemish and Dutch engraver and cartographer. He is sometimes called Jodocus Hondius the Elder to distinguish him from his son Jodocus Hondius II. Hondius is best known for his early maps of the New World and Europe, for re-establishing the reputation of the work of Gerard Mercator, and for his portraits of Francis Drake. He inherited and republished the plates of Mercator, thus reviving his legacy, also making sure to include independent revisions to his work. One of the notable figures in the Golden Age of Dutch cartography (c. 1570s–1670s), he helped establish Amsterdam as the center of cartography in Europe in the 17th century. Biography Hondius was born in Wakken and grew up in Ghent. In his early years he established himself as an engraver, instrument maker and globe maker. In 1584 he moved to London with his sister Jacomina to escape religiou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederick De Houtman
Frederick de Houtman ( – 21 October 1627) was a Dutch explorer, navigator, and colonial governor who sailed on the first Dutch expedition to the East Indies from 1595 until 1597, during which time he made observations of the southern celestial hemisphere and contributed to the creation of 12 new southern constellations. Career East Indies De Houtman was born in Gouda. De Houtman assisted fellow Dutch navigator Pieter Dirkszoon Keyser with astronomical observations during the first Dutch expedition to the East Indies from 1595 until 1597. In 1598, de Houtman sailed on a second expedition led by his brother, Cornelis de Houtman, who was killed during the voyage. Frederick was imprisoned by the Sultan of Aceh, Alauddin Riayat Syah, in northern Sumatra. He used his two years of captivity—from September 1599 until August 1601—to study the local Malay language and to make astronomical observations. These observations supplemented those made by Keyser on the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pieter Dirkszoon Keyser
Pieter Dirkszoon Keyser (occasionally Petrus Theodorus; – 11 September 1596) was a Dutch navigator and celestial cartographer who mapped several constellations on the southern celestial hemisphere. Voyages and star observation Little is known of Keyser's life outside of his astronomical observations and East Indies voyages. After making several voyages under the Portuguese flag, including one to Brazil, Keyser participated as the chief navigator and head of the steersmen for the first Dutch voyage to the East Indies (the "Eerste Schipvaart"), which left Texel with four ships on 2 April 1595 under Cornelis de Houtman. He had been trained by cartographer Petrus Plancius in mathematics and astronomy. Plancius, a key promoter to the Dutch East Indies expeditions, had instructed Keyser to map the skies in the Southern Celestial Hemisphere, southern hemisphere, which were largely uncharted at the time. When the fleet finally was able to obtain fresh supplies at Madagascar on 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
