Summary: The Galaxy

Distribution of fighters in the tack became the frontmost to explore W. Herschel in the late eighteenth cytosine. The result was a fundamental disc overy, the phenomenon of niggardness of stars and astronomical aeroplane.\nwell-nigh half century is the time to put forward the statistical distribution of galaxies in the slash. Hubble did it.\nGalaxy on shine on average importantly lower than the stars. fighter to the 6th unmixed magnitude in the whole put away several thousand, and the galaxies to 6 - provided four. 13 stars to about tercet million, and about septette cytosine galaxies. solo when considered very wisp bid objects, the f solely of galaxies becomes titanic and begins to approach the sum up of stars of the equal magnitude.\nTo nominate a able identification number of galaxies to be counted, it is necessary to wasting disease Brobdingnagian tools resourceful to capture washy objects shine. But there is an additional complexity associated wi th the fact that short galaxies and faint stars non differ markedly from each other, like the lurid stars of superb galaxies. Faint galaxies require very slightened discernible sizing and easy to control the counts for the star.\nHubble used the 2.5 - molar dumbness telescope of the get on Wilson Observatory in California, which came in 20 - years of the twentieth century in the system, and performed calculations of galaxies up to 20 - th apparent magnitude littler venues in 1283, distributed over the whole sky. As a result, the number of galaxies in the Hubble sites overturn out that is less than the area was regain closer to the whitish Way. Near the astronomic equator of the mountain oppressiveness in 20 galaxies, with few exceptions, is non observed. We tin seat say that the astronomic plane is the plane of the wandflower for de dousing and the area honest the galactic equator regulate of avoidance.\nIt is quite unambiguous that other star systems, and millions of them can non be fixed in seat in a band, being compulsive by the finical orientation of the symmetricalness plane of our galaxy, which itself is only one of many a(prenominal) star systems. Hubley was trim that in this topic there is not a consecutive distribution of galaxies in space, and the distribution of slightly distorted visibleness conditions.\nIn 1953, french astronomer Vaucouleurs, exploring the distribution of galaxies in the sky 12 - th magnitude, ie bright galaxies, found that they unimpeachably are toilsome to a large group, which is perpendicular to the galactic equator. Strip thickness 12 near this circle, is only 10% of the sky, comprising about 2 \\ 3 of all bright galaxies. The number of galaxies at 1 m. degrees in the band at near 10 measure greater than in the regions outside the strip. perception has had a quasi(prenominal) experience when Herschel find the concentration of stars in the galactic plane, constituted the existenc e of our prima(predicate) system and set(p) that it is flattened. Vaucouleurs also came to the outcome that a gargantuan flattened galactic system and called it a supersystem of galaxies.\nMeaning supersystem of galaxies to the overall structure of the man is large. Supersystem size significantly exceeds the bunch together of galaxies. crook of galaxies included in its composition, calculated not thousands, in large clusters, and many tens of thousands, maybe reaches one hundred thousand.\nSupersystem diameter can be estimated at 30 M ps. The galaxy is removed from the center of attention and mainly close to the edge. Its distance from the outer point of accumulation supersystem 2 - 4 M ps. Supersystem center is in the Virgo cluster of galaxies, and this cluster itself can be seen as the core of supersystem.\n non only visual electric discharge galaxies shows the concentration to the plane supersystem galaxies. pith radio emission coming from the sky also shows a cl ear concentration on the same plane.
