PSR B1257 12
PSR B1257+12, previously designated PSR 1257+12, alternatively designated PSR J1300+1240, is a millisecond pulsar located 2,300 light-years from the Sun in the constellation of Virgo, rotating at about 161 times per second (faster than a blender's blade). It is also named Lich, after a powerful, fictional undead creature of the same name. The pulsar has a planetary system with three known planets, named "Draugr" (PSR B1257+12 b or PSR B1257+12 A), "Poltergeist" (PSR B1257+12 c, or PSR B1257+12 B) and "Phobetor" (PSR B1257+12 d, or PSR B1257+12 C), respectively. They were both the first extrasolar planets and the first pulsar planets to be discovered; B and C in 1992 and A in 1994. A is the lowest-mass planet yet discovered by any observational technique, with somewhat less than twice the mass of Earth's moon. Nomenclature The convention that arose for designating pulsars was that of using the letters PSR (Pulsating Source of Radio) followed by the pulsar's right ...

Lich Pulsar
In fantasy fiction, a lich (; from the Old English , meaning "corpse") is a type of undead creature. Various works of fantasy fiction, such as Clark Ashton Smith's " The Empire of the Necromancers" (1932), had used ''lich'' as a general term for any corpse, animated or inanimate, before the term's specific use in fantasy role-playing games. The more recent use of the term ''lich'' for a specific type of undead creature originates from the 1976 ''Dungeons & Dragons'' role-playing game booklet '' Greyhawk'', written by Gary Gygax and Rob Kuntz. Often such a creature is the result of a willful transformation, as a powerful wizard skilled in necromancy who seeks eternal life uses rare substances in a magical ritual to become undead. Unlike zombies, which are often depicted as mindless, liches are sapient, retaining their previous intelligence and magical abilities. Liches are often depicted as holding power over lesser undead soldiers and servants. Historical background ''Lic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draugr
The draugr or draug ( non, draugr, plural ; modern is, draugur, fo, dreygur and Danish, Swedish, and no, draug) is an undead creature from the Scandinavian saga literature and folktale. Commentators extend the term ''draugr'' to the undead in medieval literature, even if it is never explicitly referred to as such in the text, and designated them rather as a ("barrow-dweller") or an , literally "again-walker" ( is, afturganga). Overview Draugar live in their graves or royal palaces, often guarding treasure buried with them in their burial mound. They are revenants, or animated corpses with a corporeal body, rather than ghosts which possess intangible spiritual bodies. Terminology Old Norse ' is defined as "a ghost, spirit, esp. the dead inhabitant of a cairn".Cleasby; Vigfusson edd. (1974) ''An Icelandic-English dictionary''. s. vdraugr/ref> Often the ''draugr'' is regarded not so much as a ghost but a revenant, i.e., the reanimated of the deceased inside the burial m ...

Magic (supernatural)
Magic, sometimes spelled magick, is an ancient Praxis (process), praxis rooted in sacred rituals, spiritual Divination, divinations, and/or cultural Lineage (anthropology), lineage—with an intention to invoke, manipulate, or otherwise manifest supernatural forces, beings, or entities in the Nature, natural, incarnate world. It is a categorical yet often ambiguous term which has been used to refer to a wide variety of beliefs and practices, frequently considered separate from both religion and science. Although connotations have varied from positive to negative at times throughout history, magic continues to have an important religious and medicinal role in many cultures today. Within Western culture, magic has been linked to ideas of the Other (philosophy), Other, foreignness, and primitivism; indicating that it is "a powerful marker of cultural difference" and likewise, a non-modern phenomenon. During the late nineteenth and early twentieth century, Western intellectuals per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Undead
The undead are beings in mythology, legend, or fiction that are deceased but behave as if alive. Most commonly the term refers to corporeal forms of formerly-alive humans, such as mummies, vampires, and zombies, who have been reanimated by supernatural means, technology, or disease. In some cases (for example in Dungeons & Dragons) the term also includes incorporeal forms of the dead, such as ghosts. The undead are featured in the belief systems of most cultures, and appear in many works of fantasy and horror fiction. The term is also occasionally used for real-life attempts to resurrect the dead with science and technology, from early experiments like Robert E. Cornish's to future sciences such as "chemical brain preservation" and "cryonics." History Bram Stoker considered using the title, ''The Un-Dead'', for his novel '' Dracula'' (1897), and use of the term in the novel is mostly responsible for the modern sense of the word. The word does appear in English before St ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NameExoWorlds
NameExoWorlds (also known as IAU NameExoWorlds) is the name of various projects managed by the International Astronomical Union (I.A.U.) to encourage names to be submitted for astronomical objects, which would later be considered for official adoption by the organization. History The first such project (NameExoWorlds I), in 2015, regarded the naming of stars and exoplanets. 573,242 votes were submitted by members by the time the contest closed on October 31, 2015, and the names of 31 exoplanets and 14 stars were selected from these. Many of the names chosen were based on world history, mythology and literature. In June 2019, another such project (NameExoWorlds II), in celebration of the organization's hundredth anniversary, in a project officially called IAU100 NameExoWorlds, welcomed countries of the world to submit names for exoplanets and their host stars. A star with an exoplanet was assigned to each country, and members of the public submitted names for them. In August 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extrasolar Planets Encyclopaedia
The Extrasolar Planets Encyclopaedia is an astronomy website, founded in Paris, France at the Meudon Observatory by Jean Schneider in February 1995, which maintains a database of all the currently known and candidate extrasolar planets, with individual pages for each planet and a full list interactive catalog spreadsheet. The main catalogue comprises databases of all of the currently confirmed extrasolar planets as well as a database of unconfirmed planet detections. The databases are frequently updated with new data from peer-reviewed publications and conferences. In their respective pages, the planets are listed along with their basic properties, including the year of planet's discovery, mass, radius, orbital period, semi-major axis, eccentricity, inclination, longitude of periastron, time of periastron, maximum time variation, and time of transit, including all error range values. The individual planet data pages also contain the data on the parent star, including name, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SIMBAD
SIMBAD (the Set of Identifications, Measurements and Bibliography for Astronomical Data) is an astronomical database of objects beyond the Solar System. It is maintained by the Centre de données astronomiques de Strasbourg (CDS), France. SIMBAD was created by merging the Catalog of Stellar Identifications (CSI) and the Bibliographic Star Index as they existed at the Meudon Computer Centre until 1979, and then expanded by additional source data from other catalogues and the academic literature. The first on-line interactive version, known as Version 2, was made available in 1981. Version 3, developed in the C language and running on UNIX stations at the Volgograd Observatory, was released in 1990. Fall of 2006 saw the release of Version 4 of the database, now stored in PostgreSQL, and the supporting software, now written entirely in Java. JP11 is a star catalogue containing about 4,000 objects. Currently it exists only as a part of the SIMBAD database. , SIMBAD contains info ...

Latin Alphabet
The Latin alphabet or Roman alphabet is the collection of letters originally used by the ancient Romans to write the Latin language. Largely unaltered with the exception of extensions (such as diacritics), it used to write English and the other modern European languages. With modifications, it is also used for other alphabets, such as the Vietnamese alphabet. Its modern repertoire is standardised as the ISO basic Latin alphabet. Etymology The term ''Latin alphabet'' may refer to either the alphabet used to write Latin (as described in this article) or other alphabets based on the Latin script, which is the basic set of letters common to the various alphabets descended from the classical Latin alphabet, such as the English alphabet. These Latin-script alphabets may discard letters, like the Rotokas alphabet, or add new letters, like the Danish and Norwegian alphabets. Letter shapes have evolved over the centuries, including the development in Medieval Latin of lower-c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
