Antonín Rükl
Antonín Rükl (22 September 1932 – 12 July 2016) was a Czech astronomer, cartographer, and author. He was born in Čáslav, Czechoslovakia. As a student, he developed what was to be a lifelong interest in astronomy. He graduated from the Czech Technical University in 1956, then joined the staff of the astronomical department of the Institute of Geodesy in Prague. In 1960, he joined the Prague Planetarium, eventually becoming deputy director and then head. He also became chairman of the Planetary Section of the Czechoslovak Astronomical Society and served as vice president of the International Planetarium Directors Conference from 1996 until 1999. He retired at the end of 1999. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomer
An astronomer is a scientist in the field of astronomy who focuses on a specific question or field outside the scope of Earth. Astronomers observe astronomical objects, such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers typically fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate Con ...

Cartographer
Cartography (; from , 'papyrus, sheet of paper, map'; and , 'write') is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality (or an imagined reality) can be modeled in ways that communicate spatial information effectively. The fundamental objectives of traditional cartography are to: * Set the map's agenda and select traits of the object to be mapped. This is the concern of map editing. Traits may be physical, such as roads or land masses, or may be abstract, such as toponyms or political boundaries. * Represent the terrain of the mapped object on flat media. This is the concern of map projections. * Eliminate the mapped object's characteristics that are irrelevant to the map's purpose. This is the concern of Cartographic generalization, generalization. * Reduce the complexity of the characteristics that will be mapped. This is also the concern of generalization. * Orchestrate the elements ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astronomy
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, galaxies, meteoroids, asteroids, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond atmosphere of Earth, Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Egyptian astronomy, Egyptians, Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Chinese astronomy, Chinese, Maya civilization, M ...

Czech Technical University
Czech Technical University in Prague (CTU) () is one of the largest universities in the Czech Republic with 8 faculties, and is one of the oldest institutes of technology in Central Europe. It is also the oldest non-military technical university in Europe. In the academic year 2020/21, Czech Technical University offered 130 degree programs in Czech and 84 in English. It was considered one of the top 10 universities in emerging Europe and Central Asia in the same year. History It was established as the Institute of Engineering Education in 1707, but as a secondary education (high school) instead of a tertiary university, by Emperor Joseph I as a response to Christian Josef Willenberg's petition addressed to preceding emperor Leopold I. In 1806, the institute of Engineering Education was transformed into Prague Polytechnical Institute (or Prague Polytechnic), i.e. a school independent of the University of Prague. This was a Europe-wide trend in the early 19th century, as p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planetárium Praha
Prague Planetarium () is a planetarium located in Bubeneč, Prague, Czech Republic, next to the Stromovka park and Výstaviště Praha. Its dome is one of the largest in the world, measuring 23.5 m in a diameter. It was opened on November 20, 1960. It is equipped with both optomechanical and digital projectors. The optomechanical ''Cosmorama'', installed in 1991, is made by Carl Zeiss AG and it is the last still working device of this type. It is currently placed on moving arms in order to be able to hide and not to shadow a modern digital projection. The digital projection system ''SkySkan Definiti'' installed in 2009 and modernized in 2014 has the highest resolution in Europe, its six Sony is a Japanese multinational conglomerate (company), conglomerate headquartered at Sony City in Minato, Tokyo, Japan.

Selenography
Selenography is the study of the surface and physical features of the Moon (also known as geography of the Moon, or selenodesy). Like geography and areography, selenography is a subdiscipline within the field of planetary science. Historically, the principal concern of selenographists was the mapping and naming of the lunar terrane identifying Lunar mare, maria, Impact crater, craters, mountain ranges, and other various features. This task was largely finished when high resolution images of the near side of the Moon, near and far side of the Moon, far sides of the Moon were obtained by orbiting spacecraft during the early space era. Nevertheless, some regions of the Moon remain poorly imaged (especially near the poles) and the exact locations of many features (like crater depths) are uncertain by several kilometers. Today, selenography is considered to be a subdiscipline of Geology of the Moon, selenology, which itself is most often referred to as simply "lunar science." History ...

Moon
The Moon is Earth's only natural satellite. It Orbit of the Moon, orbits around Earth at Lunar distance, an average distance of (; about 30 times Earth diameter, Earth's diameter). The Moon rotation, rotates, with a rotation period (lunar day) that is synchronized to its orbital period (Lunar month#Synodic month, lunar month) of 29.5 Earth days. This is the product of Earth's gravitation having tidal forces, tidally pulled on the Moon until one part of it stopped rotating away from the near side of the Moon, near side, making always the same lunar surface face Earth. Conversley, the gravitational pull of the Moon, on Earth, is the main driver of Earth's tides. In geophysical definition of planet, geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.2% that of the Earth, and its diameter is , roughly one-quarter of Earth's (about as wide as the contiguous United States). Within the Solar System, it is the List of Solar System objects by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
