Aproape toate stelele fac parte din grupuri uria\u0219e cunoscute sub numele de galaxii. Soarele este una dintre cele cel pu\u021bin 100 de miliarde de stele din galaxia noastr\u0103, Calea Lactee. Iar \u00een Univers exist\u0103 miliarde de galaxii.<\/p>\n<\/div>\n

Oriunde ne-am \u00eendrepta privirea spre cer, vedem galaxii de diferite forme \u0219i dimensiuni. Unele sunt spirale, cu bra\u021be curbate care \u00eenconjoar\u0103 un nucleu central str\u0103lucitor.<\/p>\n

Unele au o band\u0103 de stele care traverseaz\u0103 centrul, cu bra\u021be ata\u0219ate la fiecare cap\u0103t. Altele nu au deloc o form\u0103 recognoscibil\u0103. Cele mai mari galaxii arat\u0103 ca ni\u0219te bile strivite. Acestea con\u021bin p\u00e2n\u0103 la 10 milioane de milioane de stele, dar au foarte pu\u021bin gaz sau praf. Aproape toate galaxiile au o gaur\u0103 neagr\u0103 supermasiv\u0103 \u00een centru.<\/p>\n

\"When
C\u00e2nd galaxiile se ciocnesc, a\u0219a cum o demonstreaz\u0103 galaxiile Antennae<\/figcaption><\/figure>\n

Galaxiile au ap\u0103rut la doar c\u00e2teva sute de milioane de ani dup\u0103 crearea Universului. \u00cen acea perioad\u0103, acum aproximativ 13 miliarde de ani, galaxiile erau mici \u0219i mult mai apropiate unele de altele. Coliziunile erau frecvente. Pe m\u0103sur\u0103 ce galaxiile se ciocneau \u00eentre ele, acestea cre\u0219teau \u00een dimensiune \u0219i \u00ee\u0219i schimbau forma.<\/p>\n

De atunci, Universul se afl\u0103 \u00een expansiune. Majoritatea galaxiilor se \u00eendep\u0103rteaz\u0103 unele de altele cu vitez\u0103 mare, cu excep\u021bia grupurilor de galaxii, unde acestea \u201edanseaz\u0103\u201d unele \u00een jurul altora.<\/p>","protected":false},"excerpt":{"rendered":"
