Balanchine (crater)
Balanchine is a crater on the planet Mercury. It possesses a ray system of slightly bluish rays. These rays inspired the name of the crater due to their similarity to the tutu in George Balanchine's ''Serenade''. Extensive Hollows are present within Balanchine. Balanchine lies in the northeast portion of the Caloris Basin. To the northeast of Balanchine is Nervo crater, and to the southeast is March March is the third month of the year in both the Julian and Gregorian calendars. It is the second of seven months to have a length of 31 days. In the Northern Hemisphere, the meteorological beginning of spring occurs on the first day of March ....

MESSENGER
''MESSENGER'' was a NASA robotic space probe that orbited the planet Mercury between 2011 and 2015, studying Mercury's chemical composition, geology, and magnetic field. The name is a backronym for "Mercury Surface, Space Environment, Geochemistry, and Ranging", and a reference to the messenger god Mercury from Roman mythology. ''MESSENGER'' was launched aboard a Delta II rocket in August 2004. Its path involved a complex series of flybys – the spacecraft flew by Earth once, Venus twice, and Mercury itself three times, allowing it to decelerate relative to Mercury using minimal fuel. During its first flyby of Mercury in January 2008, ''MESSENGER'' became the second mission, after Mariner 10 in 1975, to reach Mercury. ''MESSENGER'' entered orbit around Mercury on March 18, 2011, becoming the first spacecraft to do so. It successfully completed its primary mission in 2012. Following two mission extensions, the spacecraft used the last of its maneuvering propellant to deor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become ...

Planet
A planet is a large, rounded astronomical body that is neither a star nor its remnant. The best available theory of planet formation is the nebular hypothesis, which posits that an interstellar cloud collapses out of a nebula to create a young protostar orbited by a protoplanetary disk. Planets grow in this disk by the gradual accumulation of material driven by gravity, a process called accretion. The Solar System has at least eight planets: the terrestrial planets Mercury, Venus, Earth and Mars, and the giant planets Jupiter, Saturn, Uranus and Neptune. These planets each rotate around an axis tilted with respect to its orbital pole. All of them possess an atmosphere, although that of Mercury is tenuous, and some share such features as ice caps, seasons, volcanism, hurricanes, tectonics, and even hydrology. Apart from Venus and Mars, the Solar System planets generate magnetic fields, and all except Venus and Mercury have natural satellites. The giant planets ...

Mercury (planet)
Mercury is the smallest planet in the Solar System and the closest to the Sun. Its orbit around the Sun takes 87.97 Earth days, the shortest of all the Sun's planets. It is named after the Roman god ' ( Mercury), god of commerce, messenger of the gods, and mediator between gods and mortals, corresponding to the Greek god Hermes (). Like Venus, Mercury orbits the Sun within Earth's orbit as an inferior planet, and its apparent distance from the Sun as viewed from Earth never exceeds 28°. This proximity to the Sun means the planet can only be seen near the western horizon after sunset or the eastern horizon before sunrise, usually in twilight. At this time, it may appear as a bright star-like object, but is more difficult to observe than Venus. From Earth, the planet telescopically displays the complete range of phases, similar to Venus and the Moon, which recurs over its synodic period of approximately 116 days. The synodic proximity of Mercury to Earth makes Mercury mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ray System
A ray system comprises radial streaks of fine ''ejecta'' thrown out during the formation of an impact crater, looking somewhat like many thin spokes coming from the hub of a wheel. The rays may extend for lengths up to several times the diameter of their originating crater, and are often accompanied by small secondary craters formed by larger chunks of ejecta. Ray systems have been identified on the Moon, Earth (Kamil Crater), Mercury, and some moons of the outer planets. Originally it was thought that they existed only on planets or moons lacking an atmosphere, but more recently they have been identified on Mars in infrared images taken from orbit by '' 2001 Mars Odyssey''s thermal imager. Rays appear at visible, and in some cases infrared wavelengths, when ejecta are made of material with different reflectivity (i.e., albedo) or thermal properties from the surface on which they are deposited. Typically, visible rays have a higher albedo than the surrounding surface. More rar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballet Tutu
A tutu is a dress worn as a costume in a classical ballet performance, often with attached bodice. It may be made of tarlatan, muslin, silk, tulle, gauze, or nylon. Modern tutus have two basic types: the Romantic tutu is soft and bell-shaped, reaching the calf or ankle; the Classical tutu is short and stiff, projecting horizontally from the waist and hip. Etymology The word tutu can refer to only the skirt part of the costume. The bodice and tutu make up what is usually the entire costume, but which is called the tutu (by synecdoche, wherein the part – the skirt – can embody the whole). The derivation of the word '' tutu'' is unknown. The word was not recorded anywhere until 1881. One theory is that it is simply derived from the word '' tulle'' (one of the materials from which it is made). A second theory is that the word comes from the slang of French children that refers to the buttocks (''cul''). During that era, the ''abonnés'' (rich male subscribers at the Paris Ope ...

Serenade (ballet)
''Serenade'' is a ballet by George Balanchine to Tchaikovsky's 1880 '' Serenade for Strings in C'', Op. 48. Serenade is credited as being George Balanchine's first full-length ballet in America. Using the students of his newly formed School of American Ballet, Balanchine choreographed this ballet for an American audience that had not been widely exposed to ballet before.Bird, "Principles of Choreography as Exemplified in the Works of George Balanchine" (1980). Master's Theses. 1851 Students of the School of American Ballet gave the first performance on Sunday, 10 June 1934 on the Felix M. Warburg estate in White Plains, N.Y., where '' Mozartiana'' had been danced the previous day. It was then presented by the Producing Company of the School of American Ballet on 6 December at the Avery Memorial Theatre of the Wadsworth Atheneum with sets by the painter William Littlefield. Balanchine presented the ballet as his response to the generous sponsorships he received during his immig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hollows (Mercury)
Hollows are a landform on the planet Mercury (planet), Mercury, discovered during the ''MESSENGER'' mission that orbited the planet from 2011 to 2015. Hollows are typically clusters of rimless depressions with flat floors and haloes of bright (high albedo) material surrounding them. Hollows are thought to form by loss of volatiles from the surface by Sublimation (phase transition), sublimation, caused by the intense solar radiation on the airless planet. They are some of the youngest features on Mercury. Hollows were first observed as bright areas within craters imaged by the Mariner 10 spacecraft in 1974, but the images were not of sufficient resolution to discern any detail. These craters include Balzac (crater), Balzac, Tyagaraja (crater), Tyagaraja, Theophanes (crater), Theophanes, Zeami (crater), Zeami, and Hopper (crater), Hopper.Dzurisin, D., 1977.

Caloris Basin
Caloris Planitia is a plain within a large impact basin on Mercury, informally named Caloris, about in diameter. It is one of the largest impact basins in the Solar System. "Calor" is Latin for "heat" and the basin is so-named because the Sun is almost directly overhead every second time Mercury passes perihelion. The crater, discovered in 1974, is surrounded by the Caloris Montes, a ring of mountains approximately tall. Appearance Caloris was discovered on images taken by the ''Mariner 10'' probe in 1974. Its name was suggested by Brian O'Leary, astronaut and member of the ''Mariner 10'' imagery team. It was situated on the terminator—the line dividing the daytime and nighttime hemispheres—at the time the probe passed by, and so half of the crater could not be imaged. Later, on January 15, 2008, one of the first photos of the planet taken by the ''MESSENGER'' probe revealed the crater in its entirety. The basin was initially estimated to be about in diameter, tho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
