Altair In Fiction
The planetary systems of stars other than the Sun and the Solar System are a staple element in many works of the science fiction genre. Overview The notion that there might be inhabited extrasolar planets can be traced at least as far back as Giordano Bruno who, in his '' De l'infinito, universo e mondi'' (''On the Infinite, Universe and Worlds'', 1584), declared that "There are then innumerable suns, and an infinite number of earths revolve around those suns, hese worlds are inhabitedif not exactly as our own, and if not more nobly, at least no less inhabited and no less nobly." Allusions to inhabitants of other stars' planetary systems remained rare in literature for some centuries thereafter. One of these is found in Voltaire's ''Micromégas'' (1752), which features a traveller from Sirius. As science fiction became established in the early 20th century, destinations such as the Moon, Mars, Venus, and other bodies within the Solar System began to seem stale. Authors invoked ...

Planetary System
A planetary system is a set of gravitationally In physics, gravity () is a fundamental interaction which causes mutual attraction between all things with mass or energy. Gravity is, by far, the weakest of the four fundamental interactions, approximately 1038 times weaker than the stron ... bound non-Star, stellar objects in or out of orbit around a star or star system. Generally speaking, systems with one or more planets constitute a planetary system, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets, planetesimals and circumstellar disks. The Sun together with the planetary system revolving around it, including Earth, forms the Solar System. The term exoplanetary system is sometimes used in reference to other planetary systems. Debris disks are also known to be common, though other objects are more difficult to observe. Of particular interest to astrobiology is the habitable zone of planetary sy ...

Extraterrestrial Life
Extraterrestrial life, colloquially referred to as alien life, is life that may occur outside Earth and which did not originate on Earth. No extraterrestrial life has yet been conclusively detected, although efforts are underway. Such life might range from simple forms like prokaryotes to intelligent beings, possibly bringing forth civilizations that might be far more advanced than humankind. The Drake equation speculates about the existence of sapient life elsewhere in the universe. The science of extraterrestrial life is known as astrobiology. Speculation about the possibility of inhabited "worlds" outside the planet Earth dates back to antiquity. Multiple early Christian writers discussed the idea of a "plurality of worlds" as proposed by earlier thinkers such as Democritus; Augustine references Epicurus's idea of innumerable worlds "throughout the boundless immensity of space" (originally expressed in his Letter to Herodotus) in ''The City of God''. In his first century p ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Barsoom
Barsoom is a fictional representation of the planet Mars created by American pulp fiction author Edgar Rice Burroughs. The first Barsoom tale was serialized as ''Under the Moons of Mars'' in 1912 and published as a novel as ''A Princess of Mars'' in 1917. Ten sequels followed over the next three decades, further extending his vision of Barsoom and adding other characters. The ''Barsoom'' series, where John Carter in the late 19th century is mysteriously transported from Earth to a Mars suffering from dwindling resources, has been cited by many well known science fiction writers as having inspired them. Elements of the books have been adapted by many writers in novels, short stories, comics, television, and film. Series Burroughs began writing the Barsoom books in the second half of 1911 and produced one volume a year between 1911 and 1914; seven more were produced between 1921 and 1941. The first Barsoom tale was serialized in '' The All-Story'' magazine as ''Under the Moons ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Edgar Rice Burroughs
Edgar Rice Burroughs (September 1, 1875 – March 19, 1950) was an American author, best known for his prolific output in the adventure, science fiction, and fantasy genres. Best-known for creating the characters Tarzan and John Carter, he also wrote the ''Pellucidar'' series, the ''Amtor'' series, and the '' Caspak'' trilogy. Tarzan was immediately popular, and Burroughs capitalized on it in every way possible, including a syndicated Tarzan comic strip, movies, and merchandise. Tarzan remains one of the most successful fictional characters to this day and is a cultural icon. Burroughs's California ranch is now the center of the Tarzana neighborhood in Los Angeles, named after the character. Burroughs was an explicit supporter of eugenics and scientific racism in both his fiction and nonfiction; Tarzan was meant to reflect these concepts. Biography Early life and family Burroughs was born on September 1, 1875, in Chicago (he later lived for many years in the suburb of ...

Barnard's Star
Barnard's Star is a red dwarf about six light-years from Earth in the constellation of Ophiuchus. It is the fourth-nearest-known individual star to the Sun after the three components of the Alpha Centauri system, and the closest star in the northern celestial hemisphere. Its stellar mass is about 14% of the Sun's. Despite its proximity, the star has a dim apparent magnitude of +9.5 and is invisible to the unaided eye; it is much brighter in the infrared than in visible light. The star is named after E. E. Barnard, an American astronomer who in 1916 measured its proper motion as 10.3 arcseconds per year relative to the Sun, the highest known for any star. The star had previously appeared on Harvard University photographic plates in 1888 and 1890. Barnard's Star is among the most studied red dwarfs because of its proximity and favorable location for observation near the celestial equator. Historically, research on Barnard's Star has focused on measuring its stellar characte ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Robert L
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

61 Cygni
61 Cygni is a binary star system in the constellation Cygnus, consisting of a pair of K-type dwarf stars that orbit each other in a period of about 659 years. Of apparent magnitude 5.20 and 6.05, respectively, they can be seen with binoculars in city skies or with the naked eye in rural areas without photopollution. 61 Cygni first attracted the attention of astronomers when its large proper motion was first demonstrated by Giuseppe Piazzi in 1804. In 1838, Friedrich Bessel measured its distance from Earth at about 10.4 light-years, very close to the actual value of about 11.4 light-years; this was the first distance estimate for any star other than the Sun, and first star to have its stellar parallax measured. Among all stars or stellar systems listed in the modern ''Hipparcos Catalogue'', 61 Cygni has the seventh-highest proper motion, and the highest among all visible stars or systems.By convention, limiting visual magnitude of 6.0 Over the course ...

A Case Of Conscience
''A Case of Conscience'' is a science fiction novel by American writer James Blish, first published in 1958. It is the story of a Jesuit who investigates an alien race that has no religion yet has a perfect, innate sense of morality, a situation which conflicts with Catholic teaching. The story was originally published as a novella in 1953, and later extended to novel-length, of which the first part is the original novella. The novel is the first part of Blish's thematic '' After Such Knowledge'' trilogy and was followed by '' Doctor Mirabilis'' and both ''Black Easter'' and ''The Day After Judgment'' (two novellas that Blish viewed as together forming the third volume of the trilogy). Few science fiction stories of the time attempted religious themes, and still fewer did this with Catholicism. Plot Part 1 In 2049, Father Ramon Ruiz-Sanchez of Peru, Clerk Regular of the Society of Jesus, is a member of a four-man team of scientists sent to the planet Lithia to determine if it c ...

Planetary Romance
Planetary romance is a subgenre of science fiction in which the bulk of the action consists of adventures on one or more exotic alien planets, characterized by distinctive physical and cultural backgrounds. Some planetary romances take place against the background of a future culture where travel between worlds by spaceship is commonplace; others, particularly the earliest examples of the genre, do not, and invoke flying carpets, astral projection, or other methods of getting between planets. In either case, it is the planetside adventures which are the focus of the story, not the mode of travel. ''The Encyclopedia of Science Fiction'' mentions two caveats as to the usage of the term. First, while the setting may be in an alien world, if "the nature or description of this world has little bearing on the story being told," as in ''A Case of Conscience'', then the book is not a planetary romance. Second, hard science fiction tales are excluded from this category, where an alien pl ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

List Of Nearest Stars
This list covers all known stars, brown dwarfs, and sub-brown dwarfs within of the Sun. So far, 131 such objects have been found, of which only 22 are bright enough to be visible without a telescope. The visible light needs to reach or exceed the dimmest brightness to be visible to the naked eye from Earth, 6.5 apparent magnitude. The known 131 objects are bound in 94 stellar systems. Of those, 103 are main sequence stars: 80 red dwarfs and 23 "typical" stars having greater mass. Additionally, astronomers have found 6 white dwarfs (stars that have exhausted all fusible hydrogen), 20 brown dwarfs, as well as 2 sub-brown dwarfs: WISE 0855−0714 (probably a rogue planet) and WISE 1741+2553. The closest system is Alpha Centauri, with Proxima Centauri as the closest star in that system, at 4.2465 light-years from Earth. The brightest, most massive and most luminous object among those 131 is Sirius A, which is also the brightest object in Earth's night sky; its white dwarf com ...
