Pavel Petrovich Parenago
Pavel Petrovich Parenago (20 March 1906 – 5 January 1960) was a Soviet scientist, astronomer, and professor. He served as the head of the Department of Stellar Astronomy at M.V. Lomonosov Moscow State University and a Corresponding Member of the Soviet Academy of Sciences. Early life and education Pavel Petrovich Parenago was born into the family of a physician on 20 March 1906, in Krasnodar, present-day Russia. He completed his middle school education in Moscow in 1922, having begun scientific work while still in senior classes. He went on to graduate from Moscow State University in 1929 as a trained and qualified scientist. Research In 1932, Parenago began studies of the structure and kinematics of the Milky Way based primarily on star data. He and a colleague, B.V. Kukarkin, began an extensive compilation of variable star data. During his studies, Parenago observed approximately 3,000 stars in the Orion nebula region of the galaxy, the nearest star creating region to the Su ...

Krasnodar
Krasnodar (; rus, Краснода́р, p=krəsnɐˈdar; ady, Краснодар), formerly Yekaterinodar (until 1920), is the largest city and the administrative centre of Krasnodar Krai, Russia. The city stands on the Kuban River in southern Russia, with a population of 1,099,344 residents, and up to 1.2 million residents in the Urban Okrug. In the past decade Krasnodar has experienced rapid population growth, rising to become the thirteenth-largest city in Russia, and the second-largest city in southern Russia, as well as the Southern Federal District. The city originated in 1793 as a fortress built by the Cossacks, and became a trading center for southern Russia. The city sustained heavy damage in World War II but was rebuilt and renovated after the war. Krasnodar is a major economic hub in southern Russia; In 2012, ''Forbes'' named Krasnodar the best city for business in Russia. Krasnodar is home to numerous sights, including the Krasnodar Stadium. Its main airport ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dwarf Star
A dwarf star is a star of relatively small size and low luminosity. Most main sequence stars are dwarf stars. The meaning of the word "dwarf" was later extended to some star-sized objects that are not stars, and compact stellar remnants which are no longer stars. History The term was originally coined in 1906 when the Danish astronomer Ejnar Hertzsprung noticed that the reddest stars – classified as K and M in the Harvard scheme – could be divided into two distinct groups. They are either much brighter than the Sun, or much fainter. To distinguish these groups, he called them "giant" and "dwarf" stars, the dwarf stars being fainter and the giants being brighter than the Sun. Most stars are currently classified under the ''Morgan Keenan System'' using the letters O, B, A, F, G, K, and M, a sequence from the hottest: '' type O'', to the coolest: '' type M''. With the development of infrared astronomy in the late 20th century the Morgan Keenan system was exten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1960 Deaths
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 '' Ab urbe condita''). The denomination 196 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.

International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

This is a worn and eroded crater formation. Attached to the northern outer rim are the satellite craters Parenago W and Parenago Z. Three small craters lie prominently along the edge the inner wall in the southeast quadrant of the interior floor. The floor is otherwise relatively level and is marked by only a few tiny craterlets. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Parenago. References * * * * * * * * * * ...

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 synod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
