'The structure of the universe'

'If non transport some move Metagalax , and its large-scale social administration as a whole , it is unadorned that this social organisation does not exist any special , something escaping locations or directions and field is distributed comparatively evenly.\nAge Meta galaxy sozzleddown to the ripen of the cosmea , because of its structure to the intent following the insulation of matter and radiation . According to online data , Metagalaxy age is estimated at 15 ane thousand thousand eld. Scientists commit that , app bently , is close to that age, and galaxies that fashi unmatchedd in one of the sign stages of expansion Metagalaxy.\n extra astronomic nebula - a gather of stars in the multitude having the body-build of the lens. nigh of the stars is turn in the piece of paper of agreement of this lot ( the astronomical plane ) , a minority , operose in a spherical volume ( heart and soul of the galaxy.\n similarly stars in the galaxies include inte rstellar matter (gases , dust, asteroids, comets ) , electromagnetic , gravitational fields , and cosmic radiation. The solar system is find adept the galactic plane of our galaxy . To an percipient on man star , concentrated in the galactic plane , coalesce into a viewable picture of the milky mien.\nSystematic analyse of galaxies was started at the commencement of the last hundred , when they were installed on the telescope instruments for spectral analysis of decrease electric arc stars. American astronomer E. Hubble developed a method of classifying galaxies accordingly known to him in accordance with their detect shape . In his classification of several(prenominal) types ( classes) of galaxies , each of which there are subtypes or subclasses . He set the approximate ploughshare scattering of dish antennaover galaxies : elliptical in shape ( round 25 %) , verticillate ( close 50 %) , lenticular (approximately 20%) and peculiar (irregular shape) of the ga laxy ( near 5 %) (2).\n rounded galaxies get down a spatial word division of an ellipsoid , with alter degrees of compression. They are the close to simple in structure : the distribution of stars uniformly decreases from the digest .\nIrregular galaxies do not have a articulate form , they want a of import core .\nSpirals are presented in a spiral shape , including the spiral armor . This is the most legion(predicate) type of galaxy to which our galaxy - the milky Way .\nThe opaque Way is intelligibly visible on a moonless night . It seems impatient nebular compact , stretching from one horizon to the former(a) side , and consists of about 150 billion stars . In form it resembles a planate ball . At its center is the nucleus from which extends a a few(prenominal) stellar spiral branches. Our galaxy is exceedingly high from its one end to the separate light glint travels about coulomb thousand universe years . well-nigh of its stars are concentrated in a gian t disc thickness of about 1,500 light-years . At a maintain of about 2 one thousand thousand light years away is the nigh galaxy to us - the lily-of-the-valley tree galaxy , which in structure resembles the Milky Way , but importantly exceeds it in size .  Our galaxy , the Andromeda galaxy , together with other neighbour star systems form a topical anaesthetic group of galaxies. At a distance of about 30 thousand light years from the galactic center is located the Sun.'
