Perseus (constellation)
Perseus is a constellation in the Northern celestial hemisphere, northern sky, being named after the Greek mythology, Greek mythological hero Perseus. It is one of the 48 ancient constellations listed by the 2nd-century astronomer Ptolemy, and among the IAU designated constellations, 88 modern constellations defined by the International Astronomical Union (IAU). It is located near several other constellations named after ancient Greek legends surrounding Perseus, including Andromeda (constellation), Andromeda to the west and Cassiopeia (constellation), Cassiopeia to the north. Perseus is also bordered by Aries (constellation), Aries and Taurus (constellation), Taurus to the south, Auriga (constellation), Auriga to the east, Camelopardalis to the north, and Triangulum to the west. Some Celestial cartography, star atlases during the early 19th century also depicted Perseus holding the disembodied head of Medusa, whose Asterism (astronomy), asterism was named together as ''Perseus e ...

1832 Births
Year 183 ( CLXXXIII) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Victorinus (or, less frequently, year 936 ''Ab urbe condita''). The denomination 183 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Astronomical Journal/Volume 16/Issue 374/Adalbert Krueger
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, professional a ...

Astrophysical Journal/Volume 4/Carl Nicolaus Adalbert Krueger
Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. As one of the founders of the discipline said, Astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space–''what'' they are, rather than ''where'' they are." Among the subjects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background. Emissions from these objects are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, ''astrophysicists'' apply concepts and methods from many disciplines of physics, including classical mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and molecular ...

Astrophysics Data System
The SAO/NASA Astrophysics Data System (ADS) is an online database of over 16 million astronomy and physics papers from both peer reviewed and non-peer reviewed sources. Abstracts are available free online for almost all articles, and full scanned articles are available in Graphics Interchange Format (GIF) and Portable Document Format (PDF) for older articles. It was developed by the National Aeronautics and Space Administration (NASA), and is managed by the Smithsonian Astrophysical Observatory. ADS is a powerful research tool and has had a significant impact on the efficiency of astronomical research since it was launched in 1992. Literature searches that previously would have taken days or weeks can now be carried out in seconds via the ADS search engine, which is custom-built for astronomical needs. Studies have found that the benefit to astronomy of the ADS is equivalent to several hundred million US dollars annually, and the system is estimated to have tripled the readership ...

Heinrich Kreutz
Heinrich Carl Friedrich Kreutz (September 8, 1854 – July 13, 1907) was a German astronomer, most notable for his studies of the orbits of several sungrazing comets, which revealed that they were all related objects, produced when a very large sun-grazing comet fragmented several hundred years previously. The group is now known as the Kreutz Sungrazers, and has produced some of the brightest comets ever seen. Kreutz was born in Siegen in 1854, and obtained his PhD at the University of Bonn in 1880 on the orbit of comet C/1861 J1. In 1882 he moved to Kiel, working at the observatory and university there. In 1896 he became the editor of the '' Astronomische Nachrichten'', the leading astronomical journal of the time, and held the position until his death in 1907. The minor planet 3635 Kreutz, discovered by Luboš Kohoutek Luboš Kohoutek (, born 29 January 1935) is a Czech astronomer and a discoverer of minor planets and comets, including Comet Kohoutek which was vis ...

Christian August Friedrich Peters
Christian August Friedrich Peters (7 September 1806 – 8 May 1880) was a German astronomer. He was the father of astronomer Carl Friedrich Wilhelm Peters. He was born in Hamburg and died in Kiel. Peters was the son of a merchant and, although he did not attend secondary school regularly, he obtained a good knowledge of mathematics and astronomy. In 1826 he became assistant to Heinrich Christian Schumacher at Altona Observatory. Schumacher encouraged him to study astronomy and Peters did a PhD under Friedrich Bessel at the University of Königsberg. In 1834 he became an assistant at Hamburg Observatory and in 1839 joined the staff of Pulkovo Observatory. In 1849 he became professor of astronomy at Königsberg and soon after succeeded Bessel as director of the observatory there. In 1854 he became director of the Altona Observatory and editor of the ''Astronomische Nachrichten''. Peters edited the journal for the rest of his life, being responsible for 58 volumes of the journal. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomische Gesellschaft
__NOTOC__ The ''Astronomische Gesellschaft'' is an astronomical society established in 1863 in Heidelberg, the second oldest astronomical society after the Royal Astronomical Society. In 1882, the ''Astronomische Gesellschaft'' founded the Central Bureau for Astronomical Telegrams at Kiel, where it remained until during World War I when it was moved to the Østervold Observatory at Copenhagen, Denmark, to be operated there by the Copenhagen University Observatory. Around the turn of the 20th century the A.G. initiated the most important star catalog of this time, the ''Astronomische Gesellschaft Katalog'' (AGK). The assembly in Danzig (now Gdańsk) in August 1939 was the last until a meeting at Göttingen in 1947, when it was re-commenced as ''Astronomische Gesellschaft in der Britischen Zone''. The post-war editorial board consisted of Chairman Albrecht Unsöld (Kiel), Otto Heckmann, J. Larink, B. Straßl, Paul ten Bruggencate, and also Max Beyer representing the amateurs of ...

Astronomische Gesellschaft Katalog
The ''Astronomische Gesellschaft Katalog'' (AGK) is an astrometric star catalogue. Compilation for the first version, AGK1, was started in 1861 by Friedrich Argelander and published between 1890 and 1954, listing 200 000 stars down to ninth magnitude. The second version, AGK2, was started in the 1920s, and published between 1951 and 1958 using photographic data obtained from the Bonn and Hamburg Observatories. The third version, AGK3, was started in 1956 and published in 1975. It contains 183,145 stars north of declination –2° with mean positional errors of ±0.13 " and mean proper motion errors of ±0.009"/year.

Peter Andreas Hansen
Peter Andreas Hansen (born 8 December 1795, Tønder, Schleswig, Denmark; died 28 March 1874, Gotha, Thuringia, Germany) was a Danish-born German astronomer. Biography The son of a goldsmith, Hansen learned the trade of a watchmaker at Flensburg, and exercised it at Berlin and Tønder, 1818–1820. He had, however, long been a student of science; and Dr Dircks, a physician practising at Tønder, prevailed with his father to send him in 1820 to Copenhagen, where he won the patronage of H.C. Schumacher and attracted the personal notice of King Frederick VI. The Danish survey was then in progress, and he acted as Schumacher's assistant in work connected with it, chiefly at the new observatory of Altona, from 1821–1825. Thence he passed on to Gotha as director of the Gotha Observatory; nor could he be tempted to relinquish the post by successive invitations to replace F.G.W. Struve at Dorpat in 1829, Friedrich Wilhelm August Argelander at Helsinki in 1837, and F.W. Bessel at Kö ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gotha
Gotha () is the fifth-largest city in Thuringia, Germany, west of Erfurt and east of Eisenach with a population of 44,000. The city is the capital of the district of Gotha and was also a residence of the Ernestine Wettins from 1640 until the end of monarchy in Germany in 1918. The House of Saxe-Coburg and Gotha originating here spawned many European rulers, including the royal houses of the United Kingdom, Belgium, Portugal (until 1910) and Bulgaria (until 1946). In the Middle Ages, Gotha was a rich trading town on the trade route ''Via Regia'' and between 1650 and 1850, Gotha saw a cultural heyday as a centre of sciences and arts, fostered by the dukes of Saxe-Gotha. The first duke, Ernest the Pious, was famous for his wise rule. In the 18th century, the ''Almanach de Gotha'' was first published in the city. The publisher Justus Perthes and the encyclopedist Joseph Meyer made Gotha a leading centre of German publishing around 1800. In the early 19th century, Gotha was a bi ...
