Ali Baba (crater)
Ali Baba is a large crater in the northern hemisphere of Saturn's moon Enceladus. Ali Baba was first discovered in ''Voyager 2'' images. It is located at 55.1° North Latitude, 22.3° West Longitude and is 39.2 kilometers across. It is located near the craters Aladdin and Samad. Ali Baba has a large dome in its interior, suggesting the crater has undergone viscous relaxation. The top of the dome even reaches higher than the crater rim. This crater is named after Ali Baba, the hero from the tale "Ali Baba and the Forty Thieves" in Sir Richard Burton's translation of ''The Book of One Thousand and One 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.

Ali Baba Crater, Enceladus
ʿAlī ibn Abī Ṭālib ( ar, عَلِيّ بْن أَبِي طَالِب; 600 – 661 CE) was the last of four Rightly Guided Caliphs to rule Islam (r. 656 – 661) immediately after the death of Muhammad, and he was the first Shia Imam. The issue of his succession caused a major rift between Muslims and divided them into Shia and Sunni groups. Ali was assassinated in the Grand Mosque of Kufa in 661 by the forces of Mu'awiya, who went on to found the Umayyad Caliphate. The Imam Ali Shrine and the city of Najaf were built around Ali's tomb and it is visited yearly by millions of devotees. Ali was a cousin and son-in-law of Muhammad, raised by him from the age of 5, and accepted his claim of divine revelation by age 11, being among the first to do so. Ali played a pivotal role in the early years of Islam while Muhammad was in Mecca and under severe persecution. After Muhammad's relocation to Medina in 622, Ali married his daughter Fatima and, among others, fathered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Ali Baba
"Ali Baba and the Forty Thieves" ( ar, علي بابا والأربعون لصا) is a folk tale from the '' One Thousand and One Nights''. It was added to the collection in the 18th century by its French translator Antoine Galland, who heard it from Syrian storyteller Hanna Diyab. As one of the most popular ''Arabian Nights'' tales, it has been widely retold and performed in many media across the world, especially for children (for whom the more violent aspects of the story are often suppressed). In the original version, Ali Baba ( ar, علي بابا ') is a poor woodcutter and an honest person who discovers the secret of a thieves' den, and enters with the magic phrase " open sesame". The thieves try to kill Ali Baba, but Ali Baba's faithful slave-girl foils their plots. Ali Baba's son marries her and Ali Baba keeps the secret of the treasure. Textual history The tale was added to the story collection '' One Thousand and One Nights'' by one of its European translators, ...

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] |
Aladdin (crater)
Aladdin is a Impact crater, crater in the northern hemisphere of Saturn's moon Enceladus (moon), Enceladus. Aladdin was first discovered in ''Voyager 2'' images. It is located at 60.7° North Latitude, 26.7° West Longitude and is 37.4 kilometers across. It is located near the craters Ali Baba (crater), Ali Baba and Samad (crater), Samad. Aladdin has a large dome in its interior, suggesting the crater has undergone some viscous relaxation. Aladdin is named after a famous hero from ''Arabian Nights'' who finds a magic lamp.

Samad (crater)
Samad is a crater in the northern hemisphere of Saturn's geologically active moon Enceladus. Samad was first discovered in '' Voyager 2'' images. It is located at 60.3° North Latitude, 4.5° West Longitude and is across. Currently available images are too low in resolution to determine if this crater has been tectonically deformed, but the lack of a prominent central dome suggests Samad has not undergone the level of viscous relaxation of other craters in its size range, like Dalilah or Ahmad. Samad is located near the larger craters Aladdin and Ali Baba. Samad is named after a Sheikh who guides Musa and Talib to the mountains in the tale "The City of Brass" from ''One Thousand and One 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.

Richard Francis Burton
Sir Richard Francis Burton (; 19 March 1821 – 20 October 1890) was a British explorer, writer, orientalist scholar,and soldier. He was famed for his travels and explorations in Asia, Africa, and the Americas, as well as his extraordinary knowledge of languages and cultures. According to one count, he spoke twenty-nine languages. Burton's best-known achievements include: a well-documented journey to Mecca in disguise, at a time when non-Muslims were forbidden access on pain of death; an unexpurgated translation of ''One Thousand and One Nights'' (commonly called ''The Arabian Nights'' in English after early translations of Antoine Galland's French version); the publication of the ''Kama Sutra'' in English; a translation of ''The Perfumed Garden'', the "Arab ''Kama Sutra''"; and a journey with John Hanning Speke as the first Europeans to visit the Great Lakes of Africa in search of the source of the Nile.

The Book Of One Thousand And One 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 ...
