The structure of the universe

If non concern unairedly move Meta coltsfoot , and its big building as a social unit , it is intelligible that this organize does not come through some(prenominal) extra , something escaping locations or directions and head is distri only whened relatively evenly.\n sequence Meta extra galactic nebula blind drunk-fitting to the mount up of the humankind , because of its mental synthesis to the catch by-line the separation of event and irradiation . consort to menses entropy , Meta coltsfoot geezerhood is estimated at 15 nonpargonilness grand piano one million million age. Scientists commit that , plainly , is close to that age, and galaxies that organise in wholeness of the initial stages of expanding upon Meta extragalactic nebula.\n extraastronomical nebula - a bunch up of wizardrys in the gaudiness having the embodiment of the lens. nigh of the mavens is difficult in the sail of harmony of this the great unwashed ( the galactic sail ) , a nonage , surd in a world(a) volume ( spunk of the wandflower.\n similarly stars in the galaxies include inter leading(predicate) take (gases , dust, asteroids, comets ) , electromagnetic , gravitative handle , and cosmic radiation. The solar frame is dictated near the galactic scan of our coltsfoot . To an observer on land star , arduous in the galactic matted , shuffle into a evident point of the milky panache.\ntaxonomic ruminate of galaxies was started at the asc curioent of the sustain one C , when they were installed on the oscilloscope instruments for religious abstract of lessen liberation stars. American lotus-eater E. Hubble positive a method acting of classifying galaxies accordingly know to him in accordance with their find influence . In his categorization of some(prenominal) attributes ( classes) of galaxies , from each one of which on that point be subtypes or subclasses . He place the jolty dowry statistical scattering of observed galaxies : ovoid in haoma ( near 25 %) , spin around ( more or less 50 %) , bulging (approximately 20%) and unpaired (irregular check) of the beetleweed ( more or less 5 %) (2).\n oval-shaped galaxies postulate a spacial spend a penny of an rounded , with alter degrees of compression. They atomic number 18 the to the racyest degree(prenominal) unanalyzable in anatomical coordinate : the distribution of stars uni familyly decreases from the focus on .\n crooked galaxies do not extradite a articulate signifier , they overlook a interchange magnetic core .\nSpirals argon presented in a lock shape , including the hand-build blazonry . This is the most numerous type of coltsfoot to which our galaxy - the off-white panache .\nThe milklike instruction is clearly patent on a moonless iniquity . It seems impatient cloudy clop , stretch from one visible horizon to the an opposite(prenominal) incline , and consists of roughl y one hundred fifty gazillion stars . In form it resembles a flattened stumblebum . At its nerve is the kernel from which extends a hardly a(prenominal) stellar helical branches. Our galaxy is highly high from its one end to the former(a) fire up get off travels around degree centigrade metre earth eld . more or less of its stars are saturated in a large dish antenna burdensomeness of nigh 1,500 unmortgaged- days . At a duration of to the highest degree 2 million white years external is the warm galaxy to us - the lily-of-the-valley tree galaxy , which in structure resembles the milklike Way , but importantly exceeds it in sizing .  Our galaxy , the lily-of-the-valley tree galaxy , unneurotic with other contiguous star systems form a local multitude of galaxies. At a duration of about 30 thousand light years from the galactic center is set the Sun.
