Poyasnenie:
Ellipticheskie galaktiki absolyutno nepohozhi na spiral'nye, k klassu kotoryh
otnositsya i nasha Galaktika. Sverhu sleva
na kartinke vy vidite NGC
4881 - bol'shuyu
ellipticheskuyu galaktiku, raspolozhennuyu na krayu gigantskogo skopleniya galaktik Volosy Veroniki.
Ellipticheskie galaktiki deistvitel'no po forme napominayut ellipsy, ne
obladayut spiral'nymi rukavami, pochti ne imeyut mezhzvezdnogo
gaza i pyli, i obnaruzhivayutsya
preimushestvenno v gusto naselennyh
skopleniyah galaktik. Ellipticheskie galaktiki obychno zhelto-krasnogo ottenka, chto takzhe
otlichaet ih ot spiral'nyh, spiral'nye rukava kotoryh sovershennogo golubye. Vse eshe
dlyatsya ser'eznye spory o tom, kak
obrazovyvalis' galaktiki raznyh tipov : mozhet byt' ellipticheskie - eto proevolyucionirovavshie
vzaimodeistvuyushie spiral'nye, mozhet byt',
naoborot, spiral'nye yavlyayutsya rezul'tatom stolknoveniya ellipticheskih
galaktik, a, mozhet byt', i pervyi i vtoroi variant vernyi. Na kartinke krome
spiral'noi galaktiki sprava vse ostal'nye galaktiki raspolozheny daleko-daleko za skopleniem galaktik Volos
Veroniki.
