Biography Hansky graduated from the Gymnasium (school)#Countries with gymnasium schools, Gymnasium and the University of Odessa. He did research on astrophysics and astrophotography in multi-year stays at the Paris Observatory, Observatory of Meudon and at the Leibniz Institute for Astrophysics Potsdam, Astrophysical Observatory Potsdam, where his main interest was the structure and activity of the solar surface. In particular he worked on the solar constant, granule (solar physics), granulation and sun spots. Hansky was a participant in several scientific expeditions. He observed from Novaya Zemlya the List of solar eclipses in the 19th century, solar eclipse of 9 August 1896 and from Alcossebre the List of solar eclipses in the 19th century, solar eclipse of 30 August 1905. In 1901 he participated in an expedition to Spitsbergen to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spitsbergen
Spitsbergen (; formerly known as West Spitsbergen; Norwegian: ''Vest Spitsbergen'' or ''Vestspitsbergen'' , also sometimes spelled Spitzbergen) is the largest and the only permanently populated island of the Svalbard archipelago in northern Norway. Constituting the westernmost bulk of the archipelago, it borders the Arctic Ocean, the Norwegian Sea, and the Greenland Sea. Spitsbergen covers an area of , making it the largest island in Norway and the 36th-largest in the world. The administrative centre is Longyearbyen. Other settlements, in addition to research outposts, are the Russian mining community of Barentsburg, the research community of Ny-Ålesund, and the mining outpost of Sveagruva. Spitsbergen was covered in of ice in 1999, which was approximately 58.5% of the island's total area. The island was first used as a whaling base in the 17th and 18th centuries, after which it was abandoned. Coal mining started at the end of the 19th century, and several permanent commun ...

19th-century Astronomers
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under Colonialism, colonial rule. It was also marked by the collapse o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ganskiy (crater)
Ganskiy is a Lunar craters, lunar impact crater that is located on the Far side (Moon), far side of the Moon. It lies to the southeast of the walled plain Hirayama (crater), Hirayama. The rim of this crater is roughly circular, with a slight hexagonal appearance. There is some wear along the rim, particularly along the southwest where a pair of small craterlets lie next to the edge. The inner sides are unremarkable, and the interior floor is relatively level with a slight rise to the south of the midpoint. There is a tiny crater near the western inner wall. This crater is sometimes listed as ''Ganskij'', ''Hansky'', or ''Hanskiy'', but ''Ganskiy'' is the spelling recognized by the International Astronomical Union, IAU.

1118 Hanskya
1118 Hanskya ( ''prov. designation'': ) is a large background asteroid, approximately in diameter, located in the outer regions of the asteroid belt. Discovered by Sergey Belyavsky and Nikolaj Ivanov in 1927, it was named after Russian astronomer Aleksey Hansky. The presumed dark C-type asteroid has a rotation period of 15.6 hours. Discovery ''Hanskya'' was discovered on 29 August 1927, by Russian astronomers Sergey Belyavsky and Nikolaj Ivanov at the Simeiz Observatory on the Crimean peninsula. The asteroid was independently discovered by two other prolific astronomers in the field, namely Karl Reinmuth at the German Heidelberg Observatory – who observed the body only one day later and announced it first – and by Belgian astronomer Eugène Delporte at Uccle Observatory on 17 September. Orbit and classification ''Hanskya'' is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbita ...

Asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

Simeiz Observatory
Simeiz Observatory (also spelled Simeis or Simeïs) was an astronomy research observatory until the mid-1950s. It is located on Mount Koshka, Crimea, , by the town of Simeiz. Part of the Crimean Astrophysical Observatory, it is currently used for laser based studies of the orbits of satellites. The Minor Planet Center (MPC) credits Simeiz Observatory as the location where a total of 150 minor planets were discovered by astronomers Grigory Neujmin, Sergey Belyavsky, Vladimir Albitsky, Grigory Shajn, Nikolaj Ivanov, Pelageya Shajn, Praskov'ja Parchomenko, Alexander Deutsch and Evgenij Skvorcov. As of 2017, the discovery of the minor planet is directly credited to Simeiz Observatory by the MPC. History The Simeiz Observatory was founded by Russian amateur astronomer Nikolai Maltsov, who later became a honored member of the Russian Academy of Sciences and after whom asteroid 749 Malzovia was named. In 1900, he built a tower for refractor at his land plot near Simei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mont Blanc
Mont Blanc (french: Mont Blanc ; it, Monte Bianco , both meaning "white mountain") is the highest mountain in the Alps and Western Europe, rising above sea level. It is the second-most prominent mountain in Europe, after Mount Elbrus, and it is the eleventh most prominent mountain summit in the world. It gives its name to the Mont Blanc massif which straddles parts of France, Italy and Switzerland. Mont Blanc's summit lies on the watershed line between the valleys of Ferret and Veny in Italy, and the valleys of Montjoie, and Arve in France. Ownership of the summit area has long been a subject of dispute between France and Italy. The Mont Blanc massif is popular for outdoor activities like hiking, climbing, trail running and winter sports like skiing, and snowboarding. The most popular climbing route to the summit of Mont Blanc is the Goûter Route, which typically takes two days. The three towns and their communes which surround Mont Blanc are Courmayeur in Aosta Valle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Solar Eclipses In The 20th Century
This is a list of solar eclipses in the 20th century. During the period 1901 to 2000 there were 228 solar eclipses of which 78 were partial, 73 were annular (two non-central), 71 were total (three non-central) and 6 were hybrids. The greatest number of eclipses in one year was five, in 1935, and one month, July 2000, had two eclipses. Notable eclipses of the 20th century * 29 May 1919: this total eclipse was photographed by Arthur Eddington to verify general relativity (see Eddington experiment) * 20 June 1955: longest total eclipse between 1901 and 2000, lasting a maximum of 7 minutes and 8 seconds * 30 June 1973: a Concorde jet flew along the path, thereby extending the length of totality to 74 min. * 29 March 1987: second hybrid eclipse in less than one year, the first being on 3 October 1986. * 11 July 1991: Solar eclipse with the shortest gamma, of only −0.00412. * 31 July 2000: the second solar eclipse within one calendar month, the first being on 1 July 2000.
