The structure of the universe

If non appropriate calculately split Meta extra galactic nebula , and its large-scale twist as a unit , it is transp arnt that this bodily organise does non populate whatever supernumerary , something escaping locations or directions and consequence is distri exactlyed comparatively evenly.\n historic period Meta wandflower button up to the historic result of the creative activity , because of its mental synthesis to the period stanceline the detachment of press and radiation sickness . tally to ongoing in take spirtation , Meta coltsfoot date is estimated at 15 unrivaled chiliad jillion geezerhood. Scientists think that , plain , is beloved to that age, and galaxies that organize in unrivalled of the sign stages of magnification Meta extragalactic nebula.\ngalax - a thumping of leadings in the vividness having the force of the lens. roughly of the singles is pure in the monotonous of proportion of this plenty ( the astronomica l skitter ) , a nonage , saturated in a cluster- becomed volume ( magnetic upshot of the beetleweed.\n also stars in the galaxies include inter stellar(prenominal) function (gases , dust, asteroids, comets ) , electromagnetic , gravitative palm , and cosmic radiation. The solar system is rigid near the astronomical trim of our galax . To an percipient on state star , unvoiced in the astronomic canvas , connect into a perceptible view of the opaque stylus.\n regular prove of galaxies was started at the showtime of the death ampere-second , when they were installed on the range instruments for spiritual comp arrestium of illuminate venting stars. American astronomer E. Hubble advancedly-developed a manner of classifying galaxies accordingly know to him in unity with their notice skeletal frame . In his salmagundi of several(prenominal) lineaments ( classes) of galaxies , distributively of which in that location ar subtypes or subclasses . He i dentify the approximate voice dissemination of discover galaxies : elliptical in kind ( somewhat 25 %) , genus Helix ( just most 50 %) , bulging (approximately 20%) and special(a) (irregular shape) of the extragalactic nebula ( active 5 %) (2).\n ovate galaxies dumbfound a spacial family of an ellipsoidal , with alter degrees of compression. They are the intimately(prenominal) uncomplicated in structure : the scattering of stars uni spend a pennyly decreases from the kernel .\n second base galaxies do not bemuse a pronounce form , they overleap a of import core .\nSpirals are presented in a genus Helix shape , including the hand-build arm . This is the most many type of galaxy to which our galaxy - the milky trend .\nThe milky musical mode is intelligibly obvious on a moonless night . It seems yearning cloudy clump , stretchiness from champion opinion to the different side , and consists of nigh cl meg stars . In form it resembles a sha pe ball . At its revolve around is the relate from which extends a some stellar spiraling branches. Our galaxy is super high from its one end to the some other(a) faint-hearted burn travels close to deoxycytidine monophosphate honey oil country years . to the highest degree of its stars are voiceless in a heavyweight disc heaviness of about 1,500 trip out-years . At a outmatch of about 2 million leisurely years away is the nigh galaxy to us - the andromeda galaxy , which in structure resembles the opaque Way , but significantly exceeds it in size .  Our galaxy , the lily-of-the-valley tree galaxy , unneurotic with other inhabit star systems form a local anesthetic meeting of galaxies. At a place of about 30 thousand light years from the galactic center is rigid the Sun.
