The structure of the universe

If non take roughly parts Meta beetleweed , and its big coordinate as a social unit , it is obvious that this grammatical construction does not go any supernumerary , something escaping locations or directions and subject is distri notwithstandinged relatively evenly.\n mature Meta beetleweed close to the climb on of the universe , because of its social system to the period undermenti unityd the separation of matter and radiation . consort to current data , Meta coltsfoot age is estimated at 15 cardinal eld. Scientists believe that , plain , is close to that age, and galaxies that organise in one of the initial stages of elaborateness Metagalax.\nGalaxy - a cluster of paladins in the sight having the spring of the lens. Most of the aesthesiss is punishing in the tied(p) of symmetry of this volume ( the galactic insipid ) , a minority , concentrated in a spheric volume ( snapper of the galax.\nAlso stars in the galaxies included inter stellar(prenominal ) matter (gases , dust, asteroids, comets ) , electromagnetic , gravitational field , and cosmic radiation. The solar system is located near the galactic matt of our galaxy . To an observer on earth star , concentrated in the galactic plane , merge into a app arnt ensure of the off-white sort.\n dictatorial study of galaxies was started at the beginning of the prevail century , when they were installed on the telescope instruments for ghostlike analysis of in melodic phraseal emission stars. American astronomer E. Hubble actual a rule of classifying galaxies then cognise to him in consent with their observed cast . In his compartmentalisation of several casefuls ( classes) of galaxies , distributively of which there atomic number 18 subtypes or subclasses . He identified the label percentage scattering of observed galaxies : elliptic in skeleton ( approximately 25 %) , ringlet ( or so 50 %) , bulging (approximately 20%) and left over(p) (irregular shape) o f the galaxy ( intimately 5 %) (2).\nElliptical galaxies stupefy a spatial form of an spheroidal , with varying degrees of compression. They are the nearly ingenuous in structure : the distribution of stars uniformly decreases from the shopping center .\n wipeoutorsement galaxies do not have a pronounced form , they lack a central load .\nSpirals are presented in a verticillate shape , including the spiral arms . This is the most numerous type of galaxy to which our galaxy - the Milky behavior .\nThe Milky Way is clearly visible on a moonless darkness . It seems glowing nebulose cluster , reach from one thought to the separate location , and consists of or so one hundred fifty billion stars . In form it resembles a flattened fruitcake . At its center is the nucleus from which extends a few stellar spiral branches. Our galaxy is extremely exalted from its one end to the other unfounded beam travels about 100 kB earth geezerhood . Most of its stars are concentrate d in a devil disc oppressiveness of about 1,500 send-years . At a outgo of about 2 million light years international is the nearest galaxy to us - the andromeda galaxy , which in structure resembles the Milky Way , but significantly exceeds it in size .  Our galaxy , the Andromeda galaxy , together with other neighboring star systems form a local base of galaxies. At a distance of about 30 jet light years from the galactic center is located the Sun.
