Nicolae Donici
Nicolae Donici (; 1/13 September 1874 – 1960) was a Romanian astronomer born in Bessarabia. Nicolae Donici (Donitch) was born into an old family of Romanian nobles from Bessarabia in the Petricani region of Chişinău. He graduated from the University in Odesa (Ukraine). Subsequently, he served as state clerk in Saint Petersburg (Russia). Concomitantly he had his own private observatory. He conducted research in countries such as Spain, Russia, Portugal, Indonesia, Egypt, Turkey, Algeria and United States. He was an honorary list of members of the Romanian Academy, member of the Romanian Academy and doctor honoris causa of the University of Heidelberg and of the Coimbra Institute in Portugal. His main scientific interest were the Sun and its eclipses, planetary astronomy, zodiacal light.The main astronomical instrument în Dubăsarii Vechi in the InterWars period was a big spectroheliograph, which allowed to make first class photographs of the Sun and stud ...

Russian Academy Of Sciences
The Russian Academy of Sciences (RAS; russian: Росси́йская акаде́мия нау́к (РАН) ''Rossíyskaya akadémiya naúk'') consists of the national academy of Russia; a network of scientific research institutes from across the Russian Federation; and additional scientific and social units such as libraries, publishing units, and hospitals. Peter the Great established the Academy (then the St. Petersburg Academy of Sciences) in 1724 with guidance from Gottfried Leibniz. From its establishment, the Academy benefitted from a slate of foreign scholars as professors; the Academy then gained its first clear set of goals from the 1747 Charter. The Academy functioned as a university and research center throughout the mid-18th century until the university was dissolved, leaving research as the main pillar of the institution. The rest of the 18th century continuing on through the 19th century consisted of many published academic works from Academy scholars and a few Ac ...

Emanuel Von Der Pahlen
Baron Emanuel A. von der Pahlen (4 July 1882–18 July 1952) was a German astronomer. He was born in St. Petersburg, Russia, but left for Germany following the revolution of 1917. He was educated at University of Göttingen, where he was awarded a Doctorate of Mathematical Sciences. Prior to World War I he joined solar eclipse expeditions in 1905, 1912 and 1914. Between the world wars, he was employed at the Astrophysikalishen Observatorium Potsdam. He taught at the University of Basel. In 1947 he published ''Einführung in die Dynamik von Sternsystemen'', a 241-page work on Galaxies. The crater Von der Pahlen on the Moon is named after him.

It was founded at the end of the 13th century in northwestern Anatolia in the town of Söğüt (modern-day Bilecik Province) by the Turkoman (ethnonym), Turkoman tribal leader Osman I. After 1354, the Ottomans crossed into Europe and, with the Ottoman wars in Europe, conquest of the Balkans, the Ottoman Anatolian beyliks, beylik was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the Fall of Constantinople, conquest of Constantinople in 1453 by Mehmed the Conqueror. Under the reign of Sule ...

Spectroheliograph
The spectroheliograph is an instrument used in astronomy which captures a photographic image of the Sun at a single wavelength of light, a monochromatic image. The wavelength is usually chosen to coincide with a spectral wavelength of one of the chemical elements present in the Sun. It was developed independently by George Ellery Hale and Henri-Alexandre Deslandres in the 1890s and further refined in 1932 by Robert R. McMath to take motion pictures. The instrument comprises a prism or diffraction grating and a narrow slit that passes a single wavelength (a monochromator). The light is focused onto a photographic medium and the slit is moved across the disk of the Sun to form a complete image. It is now possible to make a filter that transmits a narrow band of wavelengths which produces a similar image, but spectroheliographs remain in use. See also * Spectrohelioscope * Helioscope * Heliometer A heliometer (from Greek ἥλιος ''hḗlios'' "sun" and ''measure'') is an ...

Zodiacal Light
The zodiacal light (also called false dawn when seen before sunrise) is a faint glow of diffuse sunlight scattered by interplanetary dust. Brighter around the Sun, it appears in a particularly dark night sky to extend from the Sun's direction in a roughly triangular shape along the zodiac, and appears with less intensity and visibility along the whole ecliptic as the zodiacal band. Zodiacal light spans the entire sky and contributes to the natural light of a clear and moonless night sky. A related phenomenon is '' gegenschein'' (or ''counterglow''), sunlight backscattered from the interplanetary dust, appearing directly opposite to the Sun as a faint but slightly brighter oval glow. Zodiacal light is very faint, often outshined and rendered invisible by moonlight or light pollution. The interplanetary dust in the Solar System forms a thick, pancake-shaped cloud called the zodiacal cloud which straddles the ecliptic plane. The particle sizes range from 10 to 300 microm ...

Planetary Astronomy
Planetary science (or more rarely, planetology) is the scientific study of planets (including Earth), celestial bodies (such as moons, asteroids, comets) and planetary systems (in particular those of the Solar System) and the processes of their formation. It studies objects ranging in size from micrometeoroids to gas giants, aiming to determine their composition, dynamics, formation, interrelations and history. It is a strongly interdisciplinary field, which originally grew from astronomy and Earth science, and now incorporates many disciplines, including planetary geology, cosmochemistry, atmospheric science, physics, oceanography, hydrology, theoretical planetary science, glaciology, and exoplanetology. Allied disciplines include space physics, when concerned with the effects of the Sun on the bodies of the Solar System, and astrobiology. There are interrelated observational and theoretical branches of planetary science. Observational research can involve combinations of spa ...

Eclipse
An eclipse is an astronomical event that occurs when an astronomical object or spacecraft is temporarily obscured, by passing into the shadow of another body or by having another body pass between it and the viewer. This alignment of three celestial objects is known as a syzygy. Apart from syzygy, the term eclipse is also used when a spacecraft reaches a position where it can observe two celestial bodies so aligned. An eclipse is the result of either an occultation (completely hidden) or a transit (partially hidden). The term eclipse is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow. However, it can also refer to such events beyond the Earth–Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its host planet, or a moon passing into the shadow of another moon. A binary star system can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Coimbra
The University of Coimbra (UC; pt, Universidade de Coimbra, ) is a public research university in Coimbra, Portugal. First established in Lisbon in 1290, it went through a number of relocations until moving permanently to Coimbra in 1537. The university is among the oldest universities in continuous operation in the world, the oldest in Portugal, and played an influential role in the development of higher education in the Portuguese-speaking world. In 2013, UNESCO declared the university a World Heritage Site, noting its architecture, unique culture and traditions, and historical role. The contemporary university is organized into eight faculties, granting bachelor's (''licenciado''), master's (''mestre'') and doctorate (''doutor'') degrees in nearly all major fields. It lends its name to the Coimbra Group of European research universities founded in 1985, of which it was a founding member. Enrolling over 20,000 students, more than 15% of whom are international, it is one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
