Ziemia jest cz\u0119sto nazywana niebiesk\u0105 planet\u0105, poniewa\u017c jest to jedyny \u015bwiat w naszym Uk\u0142adzie S\u0142onecznym, kt\u00f3ry w znacznej cz\u0119\u015bci pokryty jest wod\u0105. Uwa\u017ca si\u0119 jednak, \u017ce pod powierzchni\u0105 wielu satelit\u00f3w, w tym gigantycznego ksi\u0119\u017cyca Saturna \u2013 Tytana \u2013 znajduj\u0105 si\u0119 oceany. Wskaz\u00f3wk\u0105 co do istnienia podpowierzchniowego oceanu na Tytanie jest odkrycie silnych p\u0142yw\u00f3w.<\/p>\n<\/div>\n

Ka\u017cdy, kto odwiedza wybrze\u017ce, wie, czym s\u0105 p\u0142ywy \u2013 dwukrotne wznoszenie si\u0119 i opadanie poziomu morza ka\u017cdego dnia. Mniej oczywiste s\u0105 natomiast p\u0142ywy, kt\u00f3re powoduj\u0105, \u017ce skorupa naszej planety unosi si\u0119 i opada o kilkadziesi\u0105t centymetr\u00f3w. P\u0142ywy te wynikaj\u0105 ze wsp\u00f3lnego oddzia\u0142ywania grawitacyjnego Ksi\u0119\u017cyca i S\u0142o\u0144ca na Ziemi\u0119. P\u0142ywy na Tytanie powstaj\u0105 w podobny spos\u00f3b. Tym razem jednak to si\u0142a grawitacyjna Saturna powoduje, \u017ce ksi\u0119\u017cyc zmienia sw\u00f3j kszta\u0142t podczas 16-dniowego obiegu wok\u00f3\u0142 planety.<\/p>\n

Zmiany kszta\u0142tu Tytana wykryto dzi\u0119ki dok\u0142adnemu \u015bledzeniu toru lotu sondy Cassini podczas jej przelot\u00f3w w pobli\u017cu tego ksi\u0119\u017cyca. R\u00f3\u017cnice w sile, z jak\u0105 Tytan oddzia\u0142ywa\u0142 na sond\u0119 Cassini, wykaza\u0142y, \u017ce przyci\u0105ganie grawitacyjne ksi\u0119\u017cyca \u2013 a co za tym idzie, jego kszta\u0142t \u2013 uleg\u0142o bardzo nieznacznej zmianie. W najdalszym punkcie, gdy si\u0142a grawitacyjna Saturna jest s\u0142absza, Tytan ma kszta\u0142t niemal kulisty, przypominaj\u0105cy pi\u0142k\u0119 do futbolu ameryka\u0144skiego. Gdy ksi\u0119\u017cyc znajduje si\u0119 najbli\u017cej Saturna, ulega rozci\u0105gni\u0119ciu, przez co przypomina raczej pi\u0142k\u0119 do rugby.<\/p>\n

Powsta\u0142e w ten spos\u00f3b p\u0142ywy powoduj\u0105, \u017ce powierzchnia Tytana unosi si\u0119 i opada o ponad 10 metr\u00f3w. Wahania te s\u0105 jednak znacznie wi\u0119ksze, ni\u017c mo\u017cna by si\u0119 spodziewa\u0107, gdyby ksi\u0119\u017cyc ten by\u0142 w ca\u0142o\u015bci sta\u0142y. Wskazuje to na istnienie pod powierzchni\u0105 oceanu, kt\u00f3rego g\u0142\u0119boko\u015b\u0107 mo\u017ce wynosi\u0107 250 km, ukrytego pod lodow\u0105 skorup\u0105 o grubo\u015bci oko\u0142o 50 km.<\/p>","protected":false},"excerpt":{"rendered":"
