Sergey Glazenap
Sergey Pavlovich Glazenap (russian: Серге́й Павлович Глазенап; 13(25) September 1848 - 12 April 1937) was a Russian and Soviet astronomer, honorary member of the Soviet Academy of Sciences (1929), and Hero of Socialist Labor (1932). In some publications, particularly in the 19th century, his last name was given as S. de Glasenapp (in French) or von Glasenapp (in German). He published ''Orbites des étoiles doubles du catalogue de Poulkova'', a study of double stars, for which he was awarded the Valz Prize in 1890.

Russian Empire
The Russian Empire was an empire and the final period of the List of Russian monarchs, Russian monarchy from 1721 to 1917, ruling across large parts of Eurasia. It succeeded the Tsardom of Russia following the Treaty of Nystad, which ended the Great Northern War. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing dynasty, Qing China. It also held colonies in North America between 1799 and 1867. Covering an area of approximately , it remains the list of largest empires, third-largest empire in history, surpassed only by the British Empire and the Mongol Empire; it ruled over a population of 125.6 million people per the Russian Empire Census, 1897 Russian census, which was the only census carried out during the entire imperial period. Owing to its geographic extent across three continents at its peak, it featured great ethnic, linguistic, re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a Federation, federal union of Republics of the Soviet Union, fifteen national republics; in practice, both Government of the Soviet Union, its government and Economy of the Soviet Union, its economy were highly Soviet-type economic planning, centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian Soviet Federative Socialist Republic, Russian SFSR. Other major cities included Saint Petersburg, Leningrad (Russian SFSR), Kyiv, Kiev (Ukrainian Soviet Socialist Republic, Ukrainian SSR), Minsk (Byelorussian Soviet Socialist Republic, Byelorussian SSR), Tas ...

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, moons, comets and galaxies – in either observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, solar astronomy, the origin or evolution of stars, or the formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational and theoretical. Observational astronomers make direct observations of celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate models of things that cannot be observed. Because it takes millions to billions of years for a system of stars or a galaxy to complete a life cycle, astronomers must observe snapsh ...

Soviet Academy Of Sciences
The Academy of Sciences of the Soviet Union was the highest scientific institution of the Soviet Union from 1925 to 1991, uniting the country's leading scientists, subordinated directly to the Council of Ministers of the Soviet Union (until 1946 – to the Council of People's Commissars of the Soviet Union). In 1991, by the decree of the President of the Russian Soviet Federative Socialist Republic, the Russian Academy of Sciences was established on the basis of the Academy of Sciences of the Soviet Union. History Creation of the Academy of Sciences of the Soviet Union The Academy of Sciences of the Soviet Union was formed by a resolution of the Central Executive Committee and the Council of People's Commissars of the Soviet Union dated July 27, 1925 on the basis of the Russian Academy of Sciences (before the February Revolution – the Imperial Saint Petersburg Academy of Sciences). In the first years of Soviet Russia, the Institute of the Academy of Sciences was perceived rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hero Of Socialist Labor
The Hero of Socialist Labour (russian: links=no, Герой Социалистического Труда, Geroy Sotsialisticheskogo Truda) was an honorific title in the Soviet Union and other Warsaw Pact countries from 1938 to 1991. It represented the highest degree of distinction in the USSR and was awarded for exceptional achievements in Soviet industry and culture. It provided a similar status to the title of Hero of the Soviet Union, which was awarded for heroic deeds, but differed in that it was not awarded to foreign citizens. History The Title "Hero of Socialist Labour" was introduced by decree of the Presidium of the Supreme Soviet of the Soviet Union on December 27, 1938. Originally, Heroes of Socialist Labour were awarded the highest decoration of the Soviet Union, the Order of Lenin, and a diploma from the Presidium of the Supreme Soviet of the Soviet Union. In order to distinguish the Heroes of Socialist Labour from other Order of Lenin recipients, the "Hamm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Star
In observational astronomy, a double star or visual double is a pair of stars that appear close to each other as viewed from Earth, especially with the aid of optical telescopes. This occurs because the pair either forms a binary star (i.e. a binary system of stars in mutual orbit, gravitationally bound to each other) or is an ''optical double'', a chance line-of-sight alignment of two stars at different distances from the observer. Binary stars are important to stellar astronomers as knowledge of their motions allows direct calculation of stellar mass and other stellar parameters. The only (possible) case of "binary star" whose two components are separately visible to the naked eye is the case of Mizar and Alcor (though actually a multiple-star system), but it is not known for sure whether Mizar and Alcor are gravitationally bound. Since the beginning of the 1780s, both professional and amateur double star observers have telescopically measured the distances and angles betwe ...

Valz Prize
The Valz Prize ''(Prix Valz)'' was awarded by the French Academy of Sciences, from 1877 through 1970, to honor advances in astronomy. History The Valz Prize was established in June 1874 when the widow of astronomer Benjamin Valz, Marie Madeleine Julie Malhian, donated 10,000 francs to establish a prize in honor of her late husband. The Valz Prize was to be awarded for work of similar stature as that honored by the pre-existing Lalande Prize. The first Valz Prize was awarded in 1877 to brothers Paul and Prosper Henry, and was for the sum of 460 francs. Save for 1924, the French Academy of Sciences awarded the Valz Prize annually from 1877 to 1943. After 1943, the prize was awarded only sporadically (only once per decade from 1950 to 1970). In 1970 the Valz Prize was combined with the Lalande Prize to create the Lalande-Valz Prize, which continued to be awarded through 1996. In 1997, that prize was combined with numerous other Academy prizes to create the Grande Médaille. Lis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glazenap (crater)
Glazenap is a lunar impact crater that is located on the Moon's far side. It lies to the south-southwest of the huge walled plain Mendeleev, and to the northwest of the crater Pannekoek. This crater is nearly circular, and has not been significantly eroded. However, a small crater lies across the northwestern rim. The loose material deposited along the inner walls has accumulated at the base in a ring of scree Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. Talus deposits typically ha ... about the interior floor.

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
