Szinte minden csillag olyan hatalmas csoportokhoz tartozik, amelyeket galaxisoknak nevez\u00fcnk. A Nap a Tej\u00fat nev\u0171 galaxisunkban tal\u00e1lhat\u00f3 legal\u00e1bb 100 milli\u00e1rd csillag egyike. Az Univerzumban pedig milli\u00e1rdnyi galaxis l\u00e9tezik.<\/p>\n<\/div>\n

B\u00e1rhov\u00e1 is n\u00e9zz\u00fcnk az \u00e9gen, mindenfel\u00e9 k\u00fcl\u00f6nb\u00f6z\u0151 alak\u00fa \u00e9s m\u00e9ret\u0171 galaxisokat l\u00e1thatunk. N\u00e9h\u00e1nyuk spir\u00e1lgalaxis, amelynek \u00edvelt karjai egy f\u00e9nyes k\u00f6zponti mag k\u00f6r\u00e9 tekerednek.<\/p>\n

N\u00e9h\u00e1nynak a k\u00f6zep\u00e9n csillagokb\u00f3l \u00e1ll\u00f3 s\u00e1v h\u00faz\u00f3dik, amelynek mindk\u00e9t v\u00e9g\u00e9n karok kapcsol\u00f3dnak. M\u00e1soknak egy\u00e1ltal\u00e1n nincs felismerhet\u0151 alakjuk. A legnagyobb galaxisok lap\u00edtott g\u00f6mb\u00f6kh\u00f6z hasonl\u00edtanak. Ak\u00e1r 10 milli\u00f3 milli\u00f3 csillagot is tartalmazhatnak, de g\u00e1zuk \u00e9s poruk nagyon kev\u00e9s. Szinte minden galaxis k\u00f6zep\u00e9n egy szupermassz\u00edv fekete lyuk tal\u00e1lhat\u00f3.<\/p>\n

\"When
Amikor a galaxisok \u00f6ssze\u00fctk\u00f6znek \u2013 ahogyan azt az Antennae-galaxisok p\u00e9ld\u00e1ja is mutatja<\/figcaption><\/figure>\n

A galaxisok mind\u00f6ssze n\u00e9h\u00e1ny sz\u00e1zmilli\u00f3 \u00e9vvel az Univerzum keletkez\u00e9se ut\u00e1n j\u00f6ttek l\u00e9tre. Abban az id\u0151ben, k\u00f6r\u00fclbel\u00fcl 13 milli\u00e1rd \u00e9vvel ezel\u0151tt, a galaxisok kicsik voltak \u00e9s sokkal k\u00f6zelebb helyezkedtek el egym\u00e1shoz. Az \u00fctk\u00f6z\u00e9sek gyakoriak voltak. Ahogy a galaxisok egym\u00e1sba csap\u00f3dtak, m\u00e9ret\u00fck n\u0151tt \u00e9s alakjuk megv\u00e1ltozott.<\/p>\n

Az\u00f3ta az Univerzum folyamatosan t\u00e1gul. A legt\u00f6bb galaxis nagy sebess\u00e9ggel t\u00e1volodik egym\u00e1st\u00f3l, kiv\u00e9ve a galaxishalmazokat, ahol a galaxisok egym\u00e1s k\u00f6r\u00fcl keringenek.<\/p>","protected":false},"excerpt":{"rendered":"
