Taurus Poniatovii
Taurus Poniatovii (Latin for ''Poniatowski's bull'') was a constellation created by the former rector of Vilnius University, Marcin Odlanicki Poczobutt, in 1777 to honor Stanislaus Poniatowski, King of Poland and Grand Duke of Lithuania. It consisted of stars that are today considered part of Ophiuchus and Aquila. It is no longer in use. It was wedged in between Ophiuchus, Aquila and Serpens Cauda. A depiction of the constellation can be found on the wall of the Vilnius University Astronomical Observatory. The stars The stars were picked for the resemblance of their arrangement to the Hyades group which form the "head" of Taurus. Before the definition of Taurus Poniatovii, some of these had been part of the obsolete constellation River Tigris. The brightest of these stars is 72 Oph (3.7 magnitude) in the "horn" of Taurus Poniatovii. The "face" of Taurus Poniatovii is formed by 67 Oph (4.0), 68 Oph (4.4) and 70 Oph (4.0). The five brightest stars belong to loose open clu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

72 Oph
72 Ophiuchi is a binary star system in the equatorial constellation of Ophiuchus. It is visible to the naked eye as a faint, white-hued point of light with a combined apparent visual magnitude of 3.73. It is located approximately 86.9 light years away from the Sun based on parallax, but is moving closer with a heliocentric radial velocity of -23.9 km/s. As of 2008, the pair had an angular separation of . According to Gray et al. (2003), the primary component has a stellar classification of A5 V, matching an A-type main-sequence star. Cowley et al. (1969) had assigned it to a class of A4 IVs, suggesting it is a sharp- lined (s) subgiant star. The latter class is still in use by some sources. The primary is 250 million years old with double the mass of the Sun and is spinning with a moderate projected rotational velocity of 65 km/s. It is radiating 20 times the luminosity of the Sun from its photosphere at an effective temperature of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Former Constellations
Former constellations are old historical Western constellations that for various reasons are no longer widely recognised or are not officially recognised by the International Astronomical Union (IAU). Prior to 1930, many of these defunct constellations were traditional in one or more countries or cultures. Some only lasted decades but others were referred to over many centuries. All are now recognised only for having classical or historical value. Many former constellations had complex Latinised names after objects, people, or mythological or zoological creatures. Others with unwieldy names were shortened for convenience. For example, Scutum Sobiescianum was reduced to Scutum, Mons Mensae to Mensa, and Apparatus Sculptoris to Sculptor. Some of the Northern Sky's former constellations were placed in the less populated regions between the traditional brighter constellations just to fill gaps. In the Southern Sky, new constellations were often created from about the 15th centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Vienna
The Battle of Vienna; pl, odsiecz wiedeńska, lit=Relief of Vienna or ''bitwa pod Wiedniem''; ota, Beç Ḳalʿası Muḥāṣarası, lit=siege of Beç; tr, İkinci Viyana Kuşatması, lit=second siege of Vienna took place at Kahlenberg Mountain near Vienna on 1683 after the imperial city had been besieged by the Ottoman Empire for two months. The battle was fought by the Holy Roman Empire (led by the Habsburg monarchy and the Polish–Lithuanian Commonwealth, both under the command of King John III Sobieski) against the Ottomans and their vassal and tributary states. The battle marked the first time the Commonwealth and the Holy Roman Empire had cooperated militarily against the Ottomans, and it is often seen as a turning point in history, after which "the Ottoman Turks ceased to be a menace to the Christian world". In the ensuing war that lasted until 1699, the Ottomans lost almost all of Hungary to the Holy Roman Emperor Leopold I. The battle was won by the combined f ...

John III Sobieski
John III Sobieski ( pl, Jan III Sobieski; lt, Jonas III Sobieskis; la, Ioannes III Sobiscius; 17 August 1629 – 17 June 1696) was King of Poland and Grand Duke of Lithuania from 1674 until his death in 1696. Born into Polish nobility, Sobieski was educated at the Jagiellonian University and toured Europe in his youth. As a soldier and later commander, he fought in the Khmelnytsky Uprising, the Russo-Polish War and during the Swedish invasion known as the Deluge. Sobieski demonstrated his military prowess during the war against the Ottoman Empire and established himself as a leading figure in Poland and Lithuania. In 1674, he was elected monarch of the Polish–Lithuanian Commonwealth following the sudden and unexpected death of King Michael. Sobieski's 22-year reign marked a period of the Commonwealth's stabilization, much needed after the turmoil of previous conflicts. Popular among his subjects, he was an able military leader, most famous for his victory over the Tur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johannes Hevelius
Johannes Hevelius Some sources refer to Hevelius as Polish: * * * * * * * Some sources refer to Hevelius as German: * * * * *of the Royal Society * (in German also known as ''Hevel''; pl, Jan Heweliusz; – 28 January 1687) was a councillor and mayor of Gdańsk (Danzig), in the Polish–Lithuanian Commonwealth. As an astronomer, he gained a reputation as "the founder of lunar topography", and described ten new constellations, seven of which are still used by astronomers. Etymology According to the Polish Academy of Sciences (1975) the origin of the name goes back to the surname Hawke, a historical alternative spelling for the English word hawk, which changed into ''Hawelke'' or ''Hawelecke''. In Poland he is known as ''Jan Heweliusz''. Other versions of the name include Hewel, Hevel, Hevelke or Hoefel, Höwelcke, Höfelcke. According to Feliks Bentkowski (1814), during his early years he also signed as Hoefelius. Along with the Latinized version of his name, Ludwig Günth ...

Scutum (constellation)
Scutum is a small constellation. Its name is Latin for shield, and it was originally named Scutum Sobiescianum by Johannes Hevelius in 1684. Located just south of the celestial equator, its four brightest stars form a narrow diamond shape. It is one of the 88 IAU designated constellations defined in 1922. History Scutum was named in 1684 by Polish astronomer Johannes Hevelius (Jan Heweliusz), who originally named it ''Scutum Sobiescianum'' (Shield of Sobieski) to commemorate the victory of the Christian forces led by Polish King John III Sobieski (Jan III Sobieski) in the Battle of Vienna in 1683. Later, the name was shortened to Scutum. Five bright stars of Scutum ( α Sct, β Sct, δ Sct, ε Sct and η Sct) were previously known as 1, 6, 2, 3, and 9 Aquilae respectively. The constellation of Scutum was adopted by the International Astronomical Union in 1922 as one of the 88 constellations covering the entire sky, with the official abbreviation of "Sct". The const ...

Barnard's Star
Barnard's Star is a red dwarf about six light-years from Earth in the constellation of Ophiuchus. It is the fourth-nearest-known individual star to the Sun after the three components of the Alpha Centauri system, and the closest star in the northern celestial hemisphere. Its stellar mass is about 14% of the Sun's. Despite its proximity, the star has a dim apparent magnitude of +9.5 and is invisible to the unaided eye; it is much brighter in the infrared than in visible light. The star is named after E. E. Barnard, an American astronomer who in 1916 measured its proper motion as 10.3 arcseconds per year relative to the Sun, the highest known for any star. The star had previously appeared on Harvard University photographic plates in 1888 and 1890. Barnard's Star is among the most studied red dwarfs because of its proximity and favorable location for observation near the celestial equator. Historically, research on Barnard's Star has focused on measuring its stellar c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melotte 186
Melotte 186 (also known as Collinder 359) is a large, loosely bound open cluster located in the constellation Ophiuchus. It has an apparent magnitude of 3.0 and an approximate size of 240 arc-minutes. History Due to its enormous size, this cluster was never recognized as such before the 20th century. The British astronomer Philibert Jacques Melotte was the first to notice it, who described it in his 1915 catalogue of star clusters as a large group of stars scattered around the star 67 Ophiuchi. In 1931, it was re-observed by Swedish astronomer Per Collinder, who described it as a group of 15 stars devoid of appreciable concentration, providing measurements of its member stars. Characteristics Mel 186 is an object of considerable size both real and apparent, which corresponds to a low concentration of its member stars. Its distance is controversial and the various estimates depend mainly on which stars are considered effective members or not; several estimates that indicated it ...

Collinder
In astronomy, the Collinder catalogue is a catalogue of 471 open clusters by Swedish astronomer Per Collinder. It was published in 1931 as an appendix to Collinder's paper ''On structural properties of open galactic clusters and their spatial distribution''. Catalogue objects are denoted by ''Collinder'', e.g. "Collinder 399". Dated prefixes include as ''Col + catalogue number'', or ''Cr + catalogue number'', e.g. "Cr 399". Vital statistics * The catalogue contains 471 objects: 452 open clusters, 11 globular clusters, 6 Asterism (astronomy), asterisms, 1 Stellar kinematics#Moving groups, stellar moving group, and 1 Stellar kinematics#Stellar associations, stellar association. * Objects are spread out across the entire celestial sphere. * NGC 188, Cr 8 is the northernmost Collinder object, located at a declination of +85º in the constellation Camelopardalis. * Cr 411 is the southernmost Collinder object, located at a declination of -79º in the constellation Octans.

Open Cluster
An open cluster is a type of star cluster made of up to a few thousand stars that were formed from the same giant molecular cloud and have roughly the same age. More than 1,100 open clusters have been discovered within the Milky Way galaxy, and many more are thought to exist. They are loosely bound by mutual gravitational attraction and become disrupted by close encounters with other clusters and clouds of gas as they orbit the Galactic Center. This can result in a migration to the main body of the galaxy and a loss of cluster members through internal close encounters. Open clusters generally survive for a few hundred million years, with the most massive ones surviving for a few billion years. In contrast, the more massive globular clusters of stars exert a stronger gravitational attraction on their members, and can survive for longer. Open clusters have been found only in spiral and irregular galaxies, in which active star formation is occurring. Young open clusters may b ...
