Great Comet Of 1680
C/1680 V1, also called the Great Comet of 1680, Kirch's Comet, and Newton's Comet, was the first comet discovered by telescope. It was discovered by Gottfried Kirch and was one of the brightest comets of the seventeenth century. Overview The comet was discovered by Gottfried Kirch, a German astronomer, on 14 November 1680 (New Style), in Coburg, and it became one of the brightest comets of the seventeenth century – reputedly visible even in daytime – and was noted for its spectacularly long tail. Passing 0.42 au from Earth on 30 November 1680, it sped around an extremely close perihelion of on 18 December 1680, reaching its peak brightness on 29 December as it swung outward. It was last observed on 19 March 1681. JPL Horizons shows the comet has roughly a barycentric orbital period of years. the comet is about from the Sun. While the Kirch Comet of 1680–1681 was discovered by – and subsequently named for – Gottfried Kirch, credit must also be given to Eusebio Ki ...

Rotterdam
Rotterdam ( , , , lit. ''The Dam on the River Rotte'') is the second largest city and municipality in the Netherlands. It is in the province of South Holland, part of the North Sea mouth of the Rhine–Meuse–Scheldt delta, via the ''"New Meuse"'' inland shipping channel, dug to connect to the Meuse first, but now to the Rhine instead. Rotterdam's history goes back to 1270, when a dam was constructed in the Rotte. In 1340, Rotterdam was granted city rights by William IV, Count of Holland. The Rotterdam–The Hague metropolitan area, with a population of approximately 2.7 million, is the 10th-largest in the European Union and the most populous in the country. A major logistic and economic centre, Rotterdam is Europe's largest seaport. In 2020, it had a population of 651,446 and is home to over 180 nationalities. Rotterdam is known for its university, riverside setting, lively cultural life, maritime heritage and modern architecture. The near-complete destruction ...

Kepler
Johannes Kepler (; ; 27 December 1571 – 15 November 1630) was a German astronomer, mathematician, astrologer, natural philosopher and writer on music. He is a key figure in the 17th-century Scientific Revolution, best known for his laws of planetary motion, and his books ''Astronomia nova'', ''Harmonice Mundi'', and ''Epitome Astronomiae Copernicanae''. These works also provided one of the foundations for Newton's theory of universal gravitation. Kepler was a mathematics teacher at a seminary school in Graz, where he became an associate of Prince Hans Ulrich von Eggenberg. Later he became an assistant to the astronomer Tycho Brahe in Prague, and eventually the imperial mathematician to Emperor Rudolf II and his two successors Matthias and Ferdinand II. He also taught mathematics in Linz, and was an adviser to General Wallenstein. Additionally, he did fundamental work in the field of optics, invented an improved version of the refracting (or Keplerian) telescope, and wa ...

Isaac Newton
Sir Isaac Newton (25 December 1642 – 20 March 1726/27) was an English mathematician, physicist, astronomer, alchemist, theologian, and author (described in his time as a "natural philosopher"), widely recognised as one of the greatest mathematicians and physicists and among the most influential scientists of all time. He was a key figure in the philosophical revolution known as the Enlightenment. His book (''Mathematical Principles of Natural Philosophy''), first published in 1687, established classical mechanics. Newton also made seminal contributions to optics, and shares credit with German mathematician Gottfried Wilhelm Leibniz for developing infinitesimal calculus. In the , Newton formulated the laws of motion and universal gravitation that formed the dominant scientific viewpoint for centuries until it was superseded by the theory of relativity. Newton used his mathematical description of gravity to derive Kepler's laws of planetary motion, account for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kreutz Sungrazers
The Kreutz sungrazers ( ) are a family of sungrazing comets, characterized by orbits taking them extremely close to the Sun at perihelion. They are believed to be fragments of one large comet that broke up several centuries ago and are named for German astronomer Heinrich Kreutz, who first demonstrated that they were related. A Kreutz sungrazers's aphelion is about from the Sun; these sungrazers make their way from the distant outer Solar System from a patch in the sky in Canis Major, to the inner Solar System, to their perihelion point near the Sun, and then leave the inner Solar System in their return trip to their aphelion. Several members of the Kreutz family have become great comets, occasionally visible near the Sun in the daytime sky. The most recent of these was Comet Ikeya–Seki in 1965, which may have been one of the brightest comets in the last millennium. It has been suggested that another cluster of bright Kreutz system comets may begin to arrive in the inner Sola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sungrazing Comet
A sungrazing comet is a comet that passes extremely close to the Sun at perihelion – sometimes within a few thousand kilometres of the Sun's surface. Although small sungrazers can completely evaporate during such a close approach to the Sun, larger sungrazers can survive many perihelion passages. However, the strong evaporation and tidal forces they experience often lead to their fragmentation. Up until the 1880s, it was thought that all bright comets near the Sun were the repeated return of a single sungrazing comet. Then, German astronomer Heinrich Kreutz and American astronomer Daniel Kirkwood determined that, instead of the return of the same comet, each appearance was a different comet, but each were related to a group of comets that had separated from each other at an earlier passage near the Sun (at perihelion). Very little was known about the population of sungrazing comets until 1979 when coronagraphic observations allowed the detection of sungrazers. As of October 2 ...

Libra (constellation)
Libra is a constellation of the zodiac and is located in the Southern celestial hemisphere. Its name is Latin for weighing scales. Its old astronomical symbol is (♎︎). It is fairly faint, with no first magnitude stars, and lies between Virgo to the west and Scorpius to the east. Beta Librae, also known as Zubeneschamali, is the brightest star in the constellation. Three star systems are known to have planets. Features Stars Overall, there are 83 stars within the constellation's borders brighter than or equal to apparent magnitude 6.5. The brightest stars in Libra form a quadrangle that distinguishes it for the unaided observer. Traditionally, Alpha and Beta Librae are considered to represent the scales' balance beam, while Gamma and Sigma are the weighing pans. Alpha Librae, called Zubenelgenubi, is a multiple star system divisible into two stars when seen through binoculars, The primary (Alpha2 Librae) is a blue-white star of magnitude 2.7 and the secondary (Alpha1 L ...

Coquimbo, Chile
Coquimbo is a port List of cities in Chile, city, Communes of Chile, commune and Capital city, capital of the Elqui Province, located on the Pan-American Highway, in the Coquimbo Region of Chile. Coquimbo is situated in a valley south of La Serena, Chile, La Serena, with which it forms Greater La Serena with more than 400,000 inhabitants. The commune spans an area around the harbor of . The average temperature in the city lies around , and precipitation is low. History The area was originally occupied by indigenous people, who used it as a settlement and for fishing purposes. The natural harbour in Coquimbo was taken over by Pedro de Valdivia from Spain in 1550. The gold and copper industry in the region led to the city's importance as a port around 1840 and many Europeans especially from England settled in Coquimbo. In 1879 it was recognised as a town. The city was on the main path of totality of the Solar eclipse of July 2, 2019. Demographics According to the 2002 census of th ...

Bartholomew Sharp
Bartholomew Sharp (c. 1650 – 29 October 1702) was an English buccaneer and privateer. His career of piracy lasted seven years (1675–1682). In the Caribbean he took several ships, and raided the Gulf of Honduras and Portobelo. He took command of an expedition into the Pacific and spent months raiding settlements on the Pacific Coast of South America including La Serena which he torched in 1680. His flagship, taken at Panama, was the ''Trinity''. Early life Bartholomew Sharp is believed to have been born in the parish of Stepney, London, England, around 1650. He served on a privateer vessel during the Third Anglo-Dutch War. He rose to command his own vessel in the West Indies and attacked Dutch ships in the Leeward Islands. When the war ended and his commission expired, Bartholomew Sharp turned to piracy. The natural scientist and Buccaneer William Dampier suggested his first major raid was on the Central American town of Segovia. In 1679 a fleet of buccaneer vessels sailed f ...

Buccaneer
Buccaneers were a kind of privateers or free sailors particular to the Caribbean Sea during the 17th and 18th centuries. First established on northern Hispaniola as early as 1625, their heyday was from Stuart Restoration, the Restoration in 1660 until about 1688, during a time when governments were not strong enough and did not consistently attempt to suppress them. Originally the name applied to the landless hunters of wild boars and cattle in the largely uninhabited areas of Tortuga (Haiti), Tortuga and Hispaniola. The meat they caught was smoked over a slow fire in little huts the French called ''boucans'' to make ''viande boucanée'' – ''jerked meat'' or ''jerky'' – which they sold to the French corsairs, corsairs who preyed on the (largely Spanish) shipping and settlements of the Caribbean. Eventually the term was applied to the corsairs and (later) privateers themselves, also known as the Brethren of the Coast. Though corsairs, also known as ''filibusters'' or ''freeb ...
