Shahryar (crater)
Shahryar is a crater in the northern hemisphere of Saturn's moon Enceladus. Shahryar was first seen in ''Voyager 2'' images, but was seen at much higher resolution by the ''Cassini'' spacecraft. It is located at 58.3° North Latitude, 227.5° West Longitude and is across. Despite being nearly the same size as the nearby Sindbad crater, Shahryar does not exhibit a dome-like structure on its floor, suggesting it has not undergone significant viscous relaxation. In addition, there is very little evidence that it has experienced tectonic deformation, suggesting that Shahryar is a relatively young crater. Shahryār is named after the king from ''Arabian Nights'', who is told tales by Scheherazade Scheherazade () is a major female character and the storyteller in the frame narrative of the Middle Eastern collection of tales known as the ''One Thousand and One Nights''.

Shahryar Crater, Enceladus
Shahriyar ( fa, شهریار), also spelled as ''Sharyar, Sheryar'', ''Shariyar'', ''Shahryar'', ''Schahryar'', ''Shahriar'', ''Shariar'', ''Sheharyar'', ''Shaheryar'', ''Shaharyar'', ''Shehreyar'', or ''Shehiryar,'' and pronounced /sha ree YAAR/, is originally a Persian name used as one of highest titles of nobility, which is equal to 'King' or 'Grand Duke'. In fact, Shahryar consists of two words, 'Shahr' (city) and 'Yar/Yār' (friend), leading the name to be sometimes translated as "the city of friend". Therefore, the name may have two meanings in the Persian language. For example, here are some lines of Persian poetry: Ferdowsi: The king told the Iranian people () The bad time has passed () Hafez: This land was the city of friends and the origin of kind people () What happened to the kings and kindness? () Geography * Shahriar, a city in Tehran Province, Iran *Shahriar County, a county in Tehran Province * Shahriar, Chaharmahal and Bakhtiari, a village in Chaharmahal and Ba ...

Voyager 2
''Voyager 2'' is a space probe launched by NASA on August 20, 1977, to study the outer planets and interstellar space beyond the Sun's heliosphere. As a part of the Voyager program, it was launched 16 days before its twin, ''Voyager 1'', on a trajectory that took longer to reach gas giants Jupiter and Saturn but enabled further encounters with ice giants Uranus and Neptune. ''Voyager 2'' remains the only spacecraft to have visited either of the ice giant planets. ''Voyager 2'' was the fourth of five spacecraft to achieve Solar escape velocity, which allowed it to leave the Solar System. ''Voyager 2'' successfully fulfilled its primary mission of visiting the Jovian system in 1979, the Saturnian system in 1981, Uranian system in 1986, and the Neptunian system in 1989. The spacecraft is now in its extended mission of studying interstellar space. It has been operating for as of ; , it has reached a distance of from Earth. The probe entered interstellar space on November 5, 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shahryār
This is a list of characters in ''One Thousand and One Nights'' ( ''The Arabian Nights''), the classic, medieval collection of Middle-Eastern folk tales. Characters in the frame story Scheherazade Scheherazade or Shahrazad ( fa, شهرزاد}, ''Šahrzād'', or , ) is the legendary Persian queen who is the storyteller and narrator of ''The Nights''. She is the daughter of the kingdom's vizier and the older sister of Dunyazad. Against her father's wishes, she marries King Shahryar, who has vowed that he will execute a new bride every morning. For 1,001 nights, Scheherazade tells her husband a story, stopping at dawn with a cliffhanger. This forces the King to keep her alive for another day so that she could resume the tale at night. The name derives from the Persian ''šahr'' () and ''-zâd'' (); or from the Middle-Persian ''čehrāzād'', wherein ''čehr'' means 'lineage' and ''āzād'', 'noble' or 'exalted' (i.e. 'of noble or exalted lineage' or 'of noble appearance/origi ...

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 eroded ...

Saturn
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine and a half times that of Earth. It has only one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive. Saturn's interior is most likely composed of a core of iron–nickel and rock (silicon and oxygen compounds). Its core is surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally, a gaseous outer layer. Saturn has a pale yellow hue due to ammonia crystals in its upper atmosphere. An electrical current within the metallic hydrogen layer is thought to give rise to Saturn's planetary magnetic field, which is weaker than Earth's, but which has a magnetic moment 580 times that of Earth due to Saturn's larger size. Saturn's magnetic field strength is around one-twentieth of Jupiter's. The outer atmosphere is g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enceladus (moon)
Enceladus is the sixth-largest moon of Saturn (19th largest in the Solar System). It is about in diameter, about a tenth of that of Saturn's largest moon, Titan. Enceladus is mostly covered by fresh, clean ice, making it one of the most reflective bodies of the Solar System. Consequently, its surface temperature at noon only reaches , far colder than a light-absorbing body would be. Despite its small size, Enceladus has a wide range of surface features, ranging from old, heavily cratered regions to young, tectonically deformed terrain. Enceladus was discovered on August 28, 1789, by William Herschel, but little was known about it until the two Voyager spacecraft, ''Voyager 1'' and ''Voyager 2'', flew by Saturn in 1980 and 1981. In 2005, the spacecraft '' Cassini'' started multiple close flybys of Enceladus, revealing its surface and environment in greater detail. In particular, ''Cassini'' discovered water-rich plumes venting from the south polar region. Cryovolc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latitude
In geography, latitude is a coordinate that specifies the north– south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from –90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or ''parallels'', run east–west as circles parallel to the equator. Latitude and ''longitude'' are used together as a coordinate pair to specify a location on the surface of the Earth. On its own, the term "latitude" normally refers to the ''geodetic latitude'' as defined below. Briefly, the geodetic latitude of a point is the angle formed between the vector perpendicular (or ''normal'') to the ellipsoidal surface from the point, and the plane of the equator. Background Two levels of abstraction are employed in the definitions of latitude and longitude. In the first step the physical surface is modeled by the geoid, a surface which approximates the mean sea level over the ocean ...

Longitude
Longitude (, ) is a geographic coordinate that specifies the east–west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians are semicircular lines running from pole to pole that connect points with the same longitude. The prime meridian defines 0° longitude; by convention the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, England on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement. Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the differing position in relation to the Sun. Comparing local time to an absolute measure of time allows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sindbad (crater)
Sindbad is a crater in the northern hemisphere of Saturn's moon Enceladus. Sindbad was first seen in ''Voyager 2'' images, though the southern rim has been seen by '' Cassini''. It is located at 67° North Latitude, 212° West Longitude and is 29.1 kilometers across. A large, dome-like structure occupies the interior of the crater, suggesting the crater has undergone significant viscous relaxation. Sindbad is named after a character from ''Arabian Nights ''One Thousand and One Nights'' ( ar, أَلْفُ لَيْلَةٍ وَلَيْلَةٌ, italic=yes, ) is a collection of Middle Eastern folk tales compiled in Arabic during the Islamic Golden Age.

Arabian Nights
''One Thousand and One Nights'' ( ar, أَلْفُ لَيْلَةٍ وَلَيْلَةٌ, italic=yes, ) is a collection of Middle Eastern folk tales compiled in Arabic during the Islamic Golden Age. It is often known in English as the ''Arabian Nights'', from the first English-language edition (), which rendered the title as ''The Arabian Nights' Entertainment''. The work was collected over many centuries by various authors, translators, and scholars across West, Central and South Asia, and North Africa. Some tales trace their roots back to ancient and medieval Arabic, Egyptian, Sanskrit, Persian, and Mesopotamian literature. Many tales were originally folk stories from the Abbasid and Mamluk eras, while others, especially the frame story, are most probably drawn from the Pahlavi Persian work ( fa, هزار افسان, lit. ''A Thousand Tales''), which in turn relied partly on Indian elements. Common to all the editions of the ''Nights'' is the framing device of the story o ...

Scheherazade
Scheherazade () is a major female character and the storyteller in the frame narrative of the Middle Eastern collection of tales known as the ''One Thousand and One Nights''. Name According to modern scholarship, the name ''Scheherazade'' derives from the Middle Persian name , which is composed of the words ('lineage') and ('noble, exalted'). The earliest forms of Scheherazade's name in Arabic sources include (, ) in Masudi, and in Ibn al-Nadim. The name appears as in the ''Encyclopaedia of Islam'' and as in ''Encyclopædia Iranica''. Among standard 19th-century printed editions, the name appears as () in Macnaghten's Calcutta edition (1839–1842) and in the 1862 Bulaq edition, and as () in the Breslau edition (1825–1843). Muhsin Mahdi's critical edition has (). The spelling ''Scheherazade'' first appeared in English-language texts in 1801, borrowed from German usage.
