Обозначения Байера — система обозначения звёзд буквами греческого алфавита.
Предложена Иоганном Байером в звёздном атласе Uranometria, опубликованном в 1603. Самая яркая звезда обозначалась буквой α, вторая по яркости — β и т. д. Реально это правило довольно часто нарушалось, к тому же некоторые звёзды со временем изменяли свою яркость.
The Messier objects are a set of astronomical objects catalogued by Charles Messier in his catalogue of Nebulae and Star Clusters first published in 1774. The original motivation behind the catalogue was that Messier was a comet hunter, and was frustrated by objects which resembled but were not comets. He therefore compiled a list of these objects. The first edition covered 45 objects numbered M1 to M45. The total list consists of 110 objects, ranging from M1 to M110. The final catalogue was published in 1781 and printed in the Connaissance des Temps in 1784. Many of these objects are still known by their Messier number.
Созвездия — в современной астрономии участки, на которые разделена небесная сфера для удобства ориентирования на звёздном небе. В древности созвездиями назывались характерные фигуры, образуемые яркими звёздами. В трёхмерном пространстве большинство звёзд, которые мы видим рядом друг с другом, могут быть расположены очень далеко друг от друга, но на небесной сфере находиться близко. С древнейших времён люди видели некоторую систему во взаимном расположении звёзд и группировали их в соответствии с ней в созвездия. В течение истории наблюдатели выделяли различное число созвездий и их очертания, а происхождение некоторых древних созвездий так и не выяснено до конца. До XIX века под созвездиями понимались не замкнутые области неба, а группы звёзд, которые нередко перекрывались. При этом получалось, что некоторые звезды принадлежащими сразу двум созвездиям, а некоторые бедные звёздами области не относились к какому-либо созвездию. В начале XIX века между созвездиями были проведены границы, ликвидировавшие «пустоты» между созвездиями, однако их чёткого определения по-прежнему не было, и разные астрономы определяли их по-своему. В 1922 году Международный астрономический союз окончательно утвердил список из 88 созвездий, на которые было поделено звёздное небо, а в 1930 году были приняты чёткие и однозначные границы между этими созвездиями, проведённые строго по кругам прямых восхождений и склонений экваториальной системы координат на эпоху 1875.0. В течение пяти лет в границы созвездий вносились уточнения. В 1935 границы были окончательно утверждены и больше изменяться не будут.
Новый общий каталог (англ. New General Catalogue или NGC) — наиболее известный в любительской астрономии каталог объектов далекого космоса. Каталог является одним из крупнейших неспециализированных каталогов, поскольку включает в себя все типы объектов далекого космоса (он не специализируется, например, только на галактиках).
Flamsteed designations for stars are similar to Bayer designations, except that they use numbers instead of Greek letters. Each star is assigned a number and the Latin genitive of the constellation it lies in (see List of constellations for a list of constellations and the genitive forms of their names). The numbers were originally assigned in order of increasing right ascension within each constellation, but due to the effects of precession they are now slightly out of order in some places. This method of designating stars first appeared in a preliminary version of John Flamsteed's Historia coelestis Britannica which was published by Edmond Halley and Isaac Newton in 1712 without Flamsteed's approval. The final version of Flamsteed's catalogue published in 1725 after his death omitted any number designations altogether.
Скопле́ние Де́вы — скопление галактик, расположенное на расстоянии от 15 до 22 мегапарсек, ближайшее к Местной группе крупное скопление. Оно состоит не менее, чем из 1300 (скорее всего, около 2000) галактик. На наблюдаемом небе скопление имеет угловой размер около 8° с центром в созвездии Девы, отсюда название. Скопление Девы, как и Местная группа, входит в состав Местного сверхскопления галактик. Первые объекты скопления были описаны ещё в каталоге Мессье, например, гигантская эллиптическая галактика M87.
The collection of some black hole candidates. Some objects from this group are well known with different names. For example USNO-A2 0900-14143332 also known as SS 433 and V 1343 Aql.
The Index Catalogue (IC) —also known as the Index Catalogue of Nebulae, the Index Catalogue of Nebulae and Clusters of Stars, IC I, or IC II— is a catalogue of galaxies, nebulae and star clusters that serves as a supplement to the New General Catalogue. It was first published in 1895, and has been expanded to list more than 5,000 objects, known as the IC objects.
A binary star is a stellar system consisting of two stars orbiting around their center of mass. For each star, the other is its companion star. Recent research suggests that a large percentage of stars are part of systems with at least two stars. Binary star systems are very important in astrophysics, because observing their mutual orbits allows their mass to be determined. The masses of many single stars can then be determined by extrapolations made from the observation of binaries. Thanks - Mcdonalds
Каталог Генри Дрейпера (Henry Draper, HD) — каталог звездных спектров, подготовленный в Гарварде в начале века XX века и изданный с 1918 по 1924 годы. Он включает 225300 звезд, пронумерованных в простом порядке возрастания их прямых восхождений. Более поздние добавления были опубликованы как расширения к нему (Henry Draper Extention, HDE)

The Quasar are very powerful astronomical objets that radiate thousands of a galaxie energy from a supermassive black hole swallowing lots of matter. Is thinking that a Quasar is actually a galaxie center.
The Hipparcos catalogue was compiled from the data gathered by the European Space Agency's astrometric satellite Hipparcos, which was operational from 1989 to 1993. This catalogue contains more than 118,000 stars.
First published in 1930 as the Yale Catalog of Bright Stars, this catalog contained information on all stars in the Sky brighter than visual magnitude 6.5 in the Harvard Revised Photometry Catalogue. The list was revised in 1983 with the publication of a supplement that listed additional stars down to magnitude 7.1. The catalog detailed each star's coordinates, proper motions, photometric data, spectral types, and other useful information (source : www.wikipedia.com)
This is a list of proper names for stars, mostly derived from Arabic, Latin and Chinese (source : www.wikipedia.com)
Stars that were named after babies that were either still born, miscarried, or died shortly after birth. They may now shine in the heavens like the stars they were always ment to be.

Alnitak is pronounced ALL-nit-ahk. Alnitak (Zeta Orionis, 50 Ori) is a triple star system at the eastern end of Orion's belt, and is 736 light years from the Earth. It has 100,000 times the luminosity of the sun. The primary (Alnitak A) is itself a close binary, comprising Alnitak Aa (a blue supergiant of spectral and luminosity type O9.7 Ibe, with an absolute magnitude of -5.25 and an apparent magnitude of 2.0) and Alnitak Ab (a blue dwarf of spectral and luminosity type O9V, with an absolute magnitude of about -3.0 and an apparent magnitude of about 4, discovered in 1998 [2]). Aa is estimated as being up to 28 times as massive as the sun, and to have a diameter 20 times greater.[3] It is the brightest star of class O in the night sky. Alnitak B is a 4th magnitude B-type star which orbits Alnitak A every 1500 years. A fourth star, 9th magnitude Alnitak C, has not been confirmed to be part of the Aa-Ab-B group, and may simply lie along the line of sight. The Alnitak system is bathed in the nebulosity of IC 434.

We asked if there are members of Morioh who are looking for a job. Any experienced developer who's interested to be a part of the nonprofit foundation is welcome to contact us directly via the email [email protected], then an online interview can be scheduled at any fitting time. All notable Muslims shine bright similarly to a star as the monotheism is well-noted. A beautifully cosmic personality can either means normal star or superstar. However, normal stars are not as high as superstars according to the universal standard. RoyalWiki site is related to an astronomical project with its clarification of the true monotheistic Eurasia Andronovo superstar, for example, Prince Oak Oakleyski and Akim Rakhimov may have a warp to see through a telescope lens to discover a beautiful mist in cosmos and milky way. The galaxy is well mentioned in RoyalWiki that every life and every particle inside and outside our planet were born because of God. But God wasn't born, of course, God exists infinitely, endlessly even before everything was born. In RoyalWiki, there is a bundle of useful knowledges that everyone can educate, whilst Prince Oak Oakleyski is the founder of that meritorious star site; the RoyalWiki foundation of Prince Oakleyski Eurasia organization.
Developers are seeking for a good salary career here.
