Observatory Of Strasbourg
The Observatory of Strasbourg is an astronomical observatory in Strasbourg, France. History This observatory is actually Strasbourg's third observatory: the first was built in 1673 on one of the city's surrounding towers (the astronomer Julius Reichelt notably played a role in its establishment), and the second in 1828 on the roof of the buildings of the Academy. Following the Franco-Prussian War of 1870–1871, the city of Strasbourg became part of the German Empire. The University of Strasbourg was refounded in 1872, and a new observatory began construction in 1875, in the Neustadt district. The main instrument was a 50 cm Repsold refractor, which saw first light in 1880 (see Great refractor). At the time this was the largest instrument in the German Empire. In 1881, the ninth General Assembly of the Astronomische Gesellschaft met in Strasbourg to mark the official inauguration. The observatory site was selected primarily for instruction purposes and political sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jardin Botanique De L'Université De Strasbourg
The Jardin Botanique de l'Université de Strasbourg (3.5 hectares), also known as the Jardin botanique de Strasbourg and the Jardin botanique de l'Université Louis Pasteur, is a botanical garden and arboretum located at 28 rue Goethe, Strasbourg, Bas-Rhin, Alsace, France. It is open daily without charge. The garden was established in 1619 for the city's Académie (which in 1621 became the university) and is thus the second oldest botanical garden in France after that of Montpellier. It was created on the cemetery grounds of the convent Saint-Nicolas-aux-Ondes. This first site was then known as the Krutenau (plain of cabbage), and is now the Place de l'Ecole des Arts Decoratifs. This early garden was kept by the faculty of medicine. Its first inventory, published in 1670 by Marcus Mappus, listed some 1600 species. The entire university was suppressed in 1792 after the French Revolution, but the garden's director, Jean Hermann, managed to preserve not just the garden itself but a ...

Nebula
A nebula (; or nebulas) is a distinct luminescent part of interstellar medium, which can consist of ionized, neutral, or molecular hydrogen and also cosmic dust. Nebulae are often star-forming regions, such as in the Pillars of Creation in the Eagle Nebula. In these regions, the formations of gas, dust, and other materials "clump" together to form denser regions, which attract further matter and eventually become dense enough to form stars. The remaining material is then thought to form planets and other planetary system objects. Most nebulae are of vast size; some are hundreds of light-years in diameter. A nebula that is visible to the human eye from Earth would appear larger, but no brighter, from close by. The Orion Nebula, the brightest nebula in the sky and occupying an area twice the angular diameter of the full Moon, can be viewed with the naked eye but was missed by early astronomers. Although denser than the space surrounding them, most nebulae are far less dens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
André-Louis Danjon
André-Louis Danjon (; 6 April 1890 – 21 April 1967) was a French astronomer who served as director of the Observatory of Strasbourg from 1930 to 1945 and of the Paris Observatory from 1945 to 1963. He developed several astronomical instruments to examine the regularity of the rotation of the earth and among his discoveries was an acceleration of the rotation of the Earth during periods of intense solar activity occurring in 11-year cycles correlated with an increase in earthquakes. The Danjon scale is used for measuring the intensity of lunar eclipses. He noted an increase in the number of dark lunar eclipses with solar activity which is termed as the Danjon effect. Life and work Danjon was born in Caen to drapers Louis Dominique Danjon and Marie Justine Binet. He studied at the Lyce Malherbe and then went to the Ecole Normale Superieure during which time he worked at the observatory of the Societe Astronomique de France. He graduated in 1914 and was conscripted into the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adolf Berberich
Adolf Joseph Berberich (16 November 1861 – 27 April 1920) was a German astronomer best known for his work on calculating the orbits of minor planets and double stars. The minor planet 776 Berbericia was named in his honour. Early life Adolf Berberich was born on 16 November 1861 in Überlingen, Baden, to Katharina Hirt and Michael, a postman in Rastatt. From 1871 – 1880 he attended a Gymnasium (Germany), gymnasium in Rastatt and then went on to study astronomy at the University of Strasbourg until 1884, during which his family reportedly encountered serious financial difficulties. During his time there, he found himself unsatisfied by the insufficient funding for astronomy, which he blamed partly on Friedrich August Theodor Winnecke, Friedrich Winnecke and Wilhelm Schur, who headed the astronomy department and directed the Observatory of Strasbourg, Strasbourg observatory. Berberich originally planned to devote himself to the study of observational astronomy, but severe Nea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julius Bauschinger
Julius Bauschinger (January 28, 1860 – January 21, 1934) was a German astronomer. Biography Julius Bauschinger was born in Fürth, the son of the physicist Johann Bauschinger. He studied at the Universities of Munich and Berlin, graduating under the direction of Hugo Hans von Seeliger with a thesis titled "Studies on the motion of the planet Mercury" (1884). In 1882, he was part of a German expedition to Hartford, Connecticut, in order to observe the transit of Venus. From 1883, he was assistant and observer at the Munich observatory. In 1896, he was named director of the Astronomisches Rechen-Institut and professor of theoretical astronomy in Berlin, a position he held until 1909, when he became director of the Strasbourg observatory. Bauschinger was dissertation advisor for Alfred Wegener's 1905 doctoral thesis in astronomy. From 1920 to 1930, he directed the Leipzig observatory. He died in Munich in 1934.

Theodolite
A theodolite () is a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes. The traditional use has been for land surveying, but it is also used extensively for building and infrastructure construction, and some specialized applications such as meteorology and rocket launching. It consists of a moveable telescope mounted so it can rotate around horizontal and vertical axes and provide angular readouts. These indicate the orientation of the telescope, and are used to relate the first point sighted through the telescope to subsequent sightings of other points from the same theodolite position. These angles can be measured with accuracies down to microradians or seconds of arc. From these readings a plan can be drawn, or objects can be positioned in accordance with an existing plan. The modern theodolite has evolved into what is known as a total station where angles and distances are measured electronicall ...

Crypt
A crypt (from Greek κρύπτη (kryptē) ''wikt:crypta#Latin, crypta'' "Burial vault (tomb), vault") is a stone chamber beneath the floor of a church or other building. It typically contains coffins, Sarcophagus, sarcophagi, or Relic, religious relics. Originally, crypts were typically found below the main apse of a church, such as at the Abbey of Saint-Germain en Auxerre, but were later located beneath chancel, naves and transepts as well. Occasionally churches were raised high to accommodate a crypt at the ground level, such as St. Michael's Church, Hildesheim, St Michael's Church in Hildesheim, Germany. Etymology The word "crypt" developed as an alternative form of the Latin "vault" as it was carried over into Late Latin, and came to refer to the ritual rooms found underneath church buildings. It also served as a Bank vault, vault for storing important and/or sacred items. The word "crypta", however, is also the female form of ''crypto'' "hidden". The earliest known origin ...

Planetarium
A planetarium (: planetariums or planetaria) is a theatre built primarily for presenting educational and entertaining shows about astronomy and the night sky, or for training in celestial navigation. A dominant feature of most planetariums is the large dome-shaped projection screen onto which scenes of stars, planets, and other celestial objects can be made to appear and move realistically to simulate their motion. The projection can be created in various ways, such as a star ball, slide projector, video, fulldome projector systems, and lasers. Typical systems can be set to simulate the sky at any point in time, past or present, and often to depict the night sky as it would appear from any point of latitude on Earth. Planetaria range in size from the 37 meter dome in St. Petersburg, Russia (called "Planetarium No 1") to three-meter inflatable portable domes where attendees sit on the floor. The largest planetarium in the Western Hemisphere is the Jennifer Chalsty Planetariu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aladin Sky Atlas
Aladin is an interactive software sky atlas, created in France. It allows the user to visualize digitized astronomical images, superimpose entries from astronomical catalogues or databases, and interactively access related data and information from the SIMBAD database, the VizieR service and other archives for all known sources in the field. Created in 1999, Aladin has become a widely used VO portal capable of addressing challenges such as locating data of interest, accessing and exploring distributed datasets, visualizing multi-wavelength data. Compliance with existing or emerging VO standards, interconnection with other visualisation or analysis tools, and ability to easily compare heterogeneous data are key features allowing Aladin to be a powerful data exploration and integration tool, and a science enabler. Aladin is developed and maintained by the Centre de données astronomiques de Strasbourg (CDS) and released under the GNU GPL v3. See also * Centre national de la rech ...

Astronomical Catalogue
An astronomical catalogue is a list or tabulation of astronomical objects, typically grouped together because they share a common type, Galaxy morphological classification, morphology, origin, means of detection, or method of discovery. The oldest and largest are star catalogues. Hundreds have been published, including general ones and special ones for such objects as Infrared astronomy, infrared stars, variable stars, giant stars, multiple star systems, star clusters, and so forth. General catalogues for deep-sky objects or for objects other than stars are also large. Again, there are specialized ones for nebulas, galaxies, X-ray astronomy, X-ray sources, Astronomical radio source, radio sources, quasars and other classes. The same is true for asteroids, comets and other Small Solar System body, solar system bodies. Astronomical catalogues such as those for asteroids may be compiled from multiple sources, but most modern catalogues are the result of a particular astronomical su ...

VizieR
A vizier (; ; ) is a high-ranking political advisor or Minister (government), minister in the Near East. The Abbasids, Abbasid caliphs gave the title ''wazir'' to a minister formerly called ''katib'' (secretary), who was at first merely a helper but afterwards became the representative and successor of the ''dapir'' (official scribe or secretary) of the Sasanian Empire, Sassanian kings. In modern usage, the term has been used for government Minister (government), ministers in much of the Middle East and beyond. Several alternative spellings are used in English, such as ''vizir'', ''wazir'', and ''vezir''. Etymology Vizier may be derived from the Arabic ''wazara'' (), from the Semitic root ''W-Z-R''. The word is mentioned in the Quran, where Aaron is described as the ''wazir'' (helper) of Moses, as well as the word ''wizr'' (burden) which is also derived from the same root. It was later adopted as a title, in the form of ''wazīr āl Muḥammad'' () by the proto-Shi'a leaders ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
