Alpha Pegasi
Alpha Pegasi (α Pegasi, abbreviated Alpha Peg, α Peg), formally named Markab , is the third-brightest star in the constellation of Pegasus and one of the four stars in the asterism known as the Great Square of Pegasus. Properties Alpha Pegasi has a stellar classification of A0 IV, indicating that it is an A-type subgiant star that has exhausted the hydrogen at its core and has evolved beyond the main sequence. Its spectrum has also been classified as B9V and B9.5III. It is rotating rapidly, with a projected rotational velocity of 130 km/s giving a lower bound on the azimuthal velocity along the star's equator. The effective temperature of the photosphere is about 10,000 K and the star has expanded to nearly five times the radius of the Sun, emitting 165 times as much energy as the sun. Nomenclature ''α Pegasi'' ( Latinised to ''Alpha Pegasi'') is the star's Bayer designation. It bore the traditional name ''Markab'' (or ''Marchab''), which derived fr ...

Tau Pegasi
Tau Pegasi (τ Pegasi, abbreviated Tau Peg, τ Peg), formally named Salm , is a magnitude 4.6 star 162 light years away in the constellation of Pegasus. With about twice the mass of the Sun and thirty times as luminous, tt is a δ Scuti variable star with its brightness changing by a few hundredths of a magnitude over about an hour. Nomenclature ''τ Pegasi'' ( Latinised to ''Tau Pegasi'') is the star's Bayer designation. The star bore the traditional names ''Salm'', ''Kerb'' (or ''El Khereb'') and ''Markab'' (often spelled ''Markeb''), a name shared with Alpha Pegasi, k Puppis and Kappa Velorum. In 2016, the IAU organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN approved the name ''Salm'' (a homophone with the planet Samh) for this star and ''Markeb'' for the component Kappa Velorum A, both on 5 September 2017. ''Markab'' had previously been approved for Alpha Pegasi on 30 June 2016. All three are now so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
K Puppis
k Puppis (k Pup, k Puppis) is a Bayer designation given to an optical double star in the constellation Puppis, the two components being k1 Puppis and k2 Puppis. Bayer designation Note that the Bayer designation for this star is "k" not "kappa" (κ). In Bayer's original Uranometria, k Puppis was listed as ρ (rho) Navis. When Lacaille broke apart the large constellation Argo Navis into Carina, Puppis, and Vela, he re-designated the stars with Greek letters in a single sequence across all three constellations. Additionally, Lacaille used Latin letters for many additional stars. κ (kappa) is in the constellation of Vela and so there is no kappa in Puppis. The confusion also extends to the proper name Markab which properly applies to κ Velorum (and other stars) but which has also been used for k Puppis when it is called κ Puppis. Description Both k1 Puppis and k2 Puppis are bright blue B-type stars of nearly equal brightness, +4.50 and +4.62, respectively. To the ...

Kappa Velorum
Kappa Velorum (κ Velorum, abbreviated Kappa Vel, κ Vel; proper name Markeb ) is a binary star system in the southern constellation of Vela. The two components are designated Kappa Velorum A and B. From parallax measurements, this system is located at a distance of roughly from the Sun. The apparent visual magnitude is 2.48, making it readily visible to the naked eye in the southern hemisphere. It forms part of an asterism known as the False Cross along with Delta Velorum, Iota Carinae and Epsilon Carinae, so called because it is sometimes mistaken for the Southern Cross, causing errors in astronavigation. Nomenclature ''κ Velorum'' ( Latinised to ''Kappa Velorum'') is the system's Bayer designation. The designations of the two components as ''Kappa Velorum A'' and ''B'' derives from the convention used by the Washington Multiplicity Catalog (WMC) for multiple star systems, and adopted by the International Astronomical Union (IAU). The system had a traditional nam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Markab (horse)
Markab (foaled 4 February 2003) is a British-bred Thoroughbred racehorse. Originally trained in France, he did not race as a juvenile and won one minor race from six attempts as a three-year-old in 2006. He was then sold to race in England where he won three small handicap races in 2008 and the Great St. Wilfrid Stakes in the following year. After being transferred to the stable of Henry Candy he belatedly emerged as a top-class performer at the age of seven in 2010 when he won the Greenlands Stakes in Ireland before recording his biggest win in the Group One Betfred Sprint Cup. He remained in training for two more years, winning the Leisure Stakes in 2012 at the age of nine. Background Markab is a bay gelding with a small white star and white socks on his hind legs bred in England by his owner Hamdan Al Maktoum's Shadwell Stud. He was sired by Green Desert who finished second to Dancing Brave in the 2000 Guineas and won the July Cup in 1986. As a breeding stallion Green Dese ...

Margat
Margat, also known as Marqab ( ar, قلعة المرقب, ''Qalaat al-Marqab'', lit=Castle of the Watchtower), is a castle near Baniyas, Syria, which was a Crusader fortress and one of the major strongholds of the Knights Hospitaller. It is located around from the Mediterranean coast and approximately south of Baniyas. The castle remained in a poor state of preservation until 2007 when some reconstruction and renovation began. Fortress History Margat is located on a hill formed by an extinct volcano high about above sea level on the road between Tripoli and Latakia, overlooking the Mediterranean Sea. According to Arab sources, the site of Margat Castle was first fortified in 1062 by Muslims who continued to hold it within the Christian Principality of Antioch in the aftermath of the First Crusade. When the Principality was defeated at the Battle of Harran in 1104, the Byzantine Empire took advantage of their weakness and captured Margat from the Muslims. A few years later it ...

Civilizations In Babylon 5
The list of ''Babylon 5'' characters contains characters from the entire ''Babylon 5'' universe. The Babylon station was conceived as a political and cultural meeting place. As such, one of the show's many themes is the cultural and social interaction between civilizations. There are five dominant civilizations represented on Babylon 5: humans, the Narn, the Centauri, the Minbari and the Vorlons; and several dozen less powerful ones. A number of the less powerful races make up the League of Non-Aligned Worlds, who assembled as a result of the Dilgar War occurring 30 years before the start of the series. Main characters Jeffrey Sinclair / Valen Jeffrey Sinclair, played by actor Michael O'Hare, is the Commander of the Babylon 5 station in season one. After one full season, O'Hare and series executive producer/creator J. Michael Straczynski made the mutual and amicable decision for the character and actor to depart as a regular. O'Hare subsequently reprised the character of Sincl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marcab Confederacy
According to the beliefs of the Church of Scientology, the Marcab Confederacy is said to be one of the most powerful galactic civilizations still active. Church founder L. Ron Hubbard describes it as: Various planets united into a very vast civilization which has come forward up through the last 200,000 years, formed out of the fragments of earlier civilizations. In the last 10,000 years they have gone on with a sort of decadent kicked-in-the-head civilization that contains automobiles, business suits, fedora hats, telephones, spaceships — a civilization which looks almost an exact duplicate but is worse off than the current US civilization. The capital of the Confederacy is said to be ''"one of the tail stars of the Big Dipper"'', probably Alkaid, a star 108 light years distant from Earth. The Marcabians used to rule Earth at some point in the past but lost control of it due to ''"losses in war and other things"''. Marcabians The Marcabians had an oppressive political sy ...
