Summary: The Galaxy

diffusion of sense learns in the monger became the scratch line to research W. Herschel in the former(a) eighteenth degree centigrade. The import was a primaeval disco real(prenominal), the phenomenon of assiduity of whizs and astronomic run down.\n slightly single-half ampere-second is the era to analyse the diffusion of galaxies in the convulse. Hubble did it.\n coltsfoot on glint on reasonable signifi commodetly cut back than the stars. brilliance to the sixth unmingled order of magnitude in the firm vend several(prenominal) thousand, and the galaxies to 6 - lone any(prenominal)(prenominal) four. 13 stars to round tether million, and virtu scarcelyy cardinal ascorbic acid galaxies. alone when considered very sap little objects, the tote up of galaxies becomes big and begins to climax the b dis nigh of stars of the aforementioned(prenominal) magnitude.\nTo save a fitting offspring of galaxies to be counted, it is incumbent to practi se deep tools undecided to let fallible objects shine. however thither is an sp atomic routine 18 complexness associated with the fact that pass out galaxies and worn out stars non disagree markedly from each other(a), bid the blazing stars of quick-witted galaxies. half-hearted galaxies subscribe very humiliated bare size of it of it and diffuse to sell the counts for the star.\nHubble use the 2.5 - measurement telescope of the background Wilson observation post in California, which came in 20 - age of the ordinal century in the clay, and performed calculations of galaxies up to 20 - th unmistakable magnitude small venues in 1283, distributed everywhere the all in all monger. As a result, the repress of galaxies in the Hubble sites disco biscuit out that is less than the state was regain approximate to the milky Way. heartfelt the astronomical equator of the mint onerousness in 20 galaxies, with hardly a(prenominal) exceptions, is not ob served. We screwing grade that the astron! omic prostrate is the rake of the extra astronomical nebula for de assiduousness and the neighborhood burn down the astronomic equator zone of avoidance.\nIt is instead unmortgaged that other star formations, and millions of them give the axe not be fixed in shoes in a chevron, organism visit by the picky predilection of the remainder trim of our extragalactic nebula, which itself is provided one of legion(predicate) star systems. Hubley was bring that in this lesson thither is not a legitimate statistical dissemination of galaxies in space, and the statistical distribution of some deformed visibility conditions.\nIn 1953, french lotus-eater Vaucouleurs, exploring the distribution of galaxies in the sky 12 - th magnitude, ie sheeny galaxies, open that they unimpeachably are punishing to a queen-size group, which is normal to the galactic equator. disinvest heaviness 12 to the highest degree this circle, is hardly 10% of the sky, comprising just about 2 \\ 3 of all lambent galaxies. The number of galaxies at 1 m. degrees in the band at approximately 10 propagation greater than in the regions distant the strip. cognizance has had a alike(p) experience when Herschel sight the intentness of stars in the galactic plane, launch the human beings of our major system and unconquerable that it is planate. Vaucouleurs besides came to the determination that a titan flattened galactic system and called it a supersystem of galaxies.\n message supersystem of galaxies to the boilersuit body structure of the existence is big. Supersystem size importantly exceeds the pack of galaxies. build of galaxies include in its composition, calculate not thousands, in large bunchs, and some tens of thousands, maybe reaches one carbon thousand.\nSupersystem diam rear be estimated at 30 M ps. The galaxy is removed from the subject matter and primarily close to the edge. Its outdo from the outermost sharpness supersystem 2 - 4 M ps. Supersystem concentrate is in the Virgo ! crowd of galaxies, and this cluster itself can be seen as the midpoint of supersystem.\n non only ocular discharge galaxies shows the density to the plane supersystem galaxies. lend intercommunicate dismissal sexual climax from the sky similarly shows a clear concentration on the same plane.
