Prawie wszystkie gwiazdy nale\u017c\u0105 do ogromnych zbiorowisk zwanych galaktykami. S\u0142o\u0144ce jest jedn\u0105 z co najmniej 100 miliard\u00f3w gwiazd w naszej galaktyce, Drodze Mlecznej. We Wszech\u015bwiecie znajduj\u0105 si\u0119 miliardy galaktyk.<\/p>\n<\/div>\n

Gdziekolwiek spojrzymy na niebo, widzimy galaktyki o r\u00f3\u017cnych kszta\u0142tach i rozmiarach. Niekt\u00f3re z nich maj\u0105 kszta\u0142t spirali, z zakrzywionymi ramionami otaczaj\u0105cymi jasne j\u0105dro centralne.<\/p>\n

Niekt\u00f3re maj\u0105 pas gwiazd biegn\u0105cy przez \u015brodek, z ramionami rozchodz\u0105cymi si\u0119 na obu ko\u0144cach. Inne nie maj\u0105 \u017cadnego rozpoznawalnego kszta\u0142tu. Najwi\u0119ksze galaktyki wygl\u0105daj\u0105 jak sp\u0142aszczone kule. Zawieraj\u0105 nawet 10 milion\u00f3w milion\u00f3w gwiazd, ale maj\u0105 bardzo ma\u0142o gazu i py\u0142u. Prawie wszystkie galaktyki maj\u0105 w centrum supermasywn\u0105 czarn\u0105 dziur\u0119.<\/p>\n

\"When
Kiedy galaktyki zderzaj\u0105 si\u0119, jak pokazuje przyk\u0142ad galaktyk Antennych<\/figcaption><\/figure>\n

Galaktyki powsta\u0142y zaledwie kilkaset milion\u00f3w lat po powstaniu Wszech\u015bwiata. W tamtym czasie, oko\u0142o 13 miliard\u00f3w lat temu, galaktyki by\u0142y ma\u0142e i znajdowa\u0142y si\u0119 znacznie bli\u017cej siebie. Zderzenia by\u0142y powszechne. W miar\u0119 jak galaktyki zderza\u0142y si\u0119 ze sob\u0105, powi\u0119ksza\u0142y si\u0119 i zmienia\u0142y sw\u00f3j kszta\u0142t.<\/p>\n

Od tamtej pory Wszech\u015bwiat si\u0119 rozszerza. Wi\u0119kszo\u015b\u0107 galaktyk oddala si\u0119 od siebie z du\u017c\u0105 pr\u0119dko\u015bci\u0105, z wyj\u0105tkiem gromad galaktyk, w kt\u00f3rych galaktyki kr\u0105\u017c\u0105 wok\u00f3\u0142 siebie.<\/p>","protected":false},"excerpt":{"rendered":"
