A F\u00f6ldet gyakran \u201ek\u00e9k bolyg\u00f3nak\u201d nevezik, mivel a Naprendszer\u00fcnkben ez az egyetlen bolyg\u00f3, amelyet nagyr\u00e9szt v\u00edz bor\u00edt. Ugyanakkor sz\u00e1mos holdr\u00f3l, k\u00f6zt\u00fck a Szaturnusz \u00f3ri\u00e1si holdj\u00e1r\u00f3l, a Tit\u00e1nr\u00f3l is felt\u00e9telezik, hogy felsz\u00edne alatt \u00f3ce\u00e1nok h\u00faz\u00f3dnak. A Tit\u00e1n felsz\u00edn alatti \u00f3ce\u00e1nj\u00e1nak l\u00e9tez\u00e9s\u00e9re utal\u00f3 jel a nagy \u00e1rap\u00e1lyok felfedez\u00e9se.<\/p>\n<\/div>\n

Aki valaha is j\u00e1rt a tengerparton, az biztosan ismeri az \u00e1rap\u00e1lyt \u2013 a tengerszint napi k\u00e9tszeri emelked\u00e9s\u00e9t \u00e9s s\u00fcllyed\u00e9s\u00e9t. Kev\u00e9sb\u00e9 nyilv\u00e1nval\u00f3ak azok az \u00e1rap\u00e1lyok, amelyek bolyg\u00f3nk k\u00e9reg\u00e9t n\u00e9h\u00e1ny t\u00edz centim\u00e9terrel emelik meg, illetve s\u00fcllyesztik. Ezeket az \u00e1rap\u00e1lyokat a Hold \u00e9s a Nap F\u00f6ldre gyakorolt egy\u00fcttes gravit\u00e1ci\u00f3s vonz\u00e1sa okozza. A Tit\u00e1non az \u00e1rap\u00e1lyok hasonl\u00f3 m\u00f3don keletkeznek. Ez\u00fattal azonban a Szaturnusz vonz\u00e1sa az, ami miatt a hold alakja megv\u00e1ltozik a bolyg\u00f3 k\u00f6r\u00fcli 16 napos kering\u00e9se sor\u00e1n.<\/p>\n

A Tit\u00e1n alakv\u00e1ltoz\u00e1s\u00e1t a Cassini \u0171rszonda p\u00e1ly\u00e1j\u00e1nak gondos nyomon k\u00f6vet\u00e9s\u00e9vel \u00e9szlelt\u00e9k, amikor az a hold k\u00f6zel\u00e9ben rep\u00fclt el. A Tit\u00e1n \u00e1ltal a Cassinira gyakorolt vonz\u00e1s v\u00e1ltoz\u00e1sai azt mutatt\u00e1k, hogy a hold gravit\u00e1ci\u00f3s vonz\u00e1sa \u2013 \u00e9s \u00edgy alakja is \u2013 nagyon kiss\u00e9 megv\u00e1ltozott. A legk\u00fcls\u0151 pontj\u00e1n, ahol a Szaturnusz vonz\u00e1sa gyeng\u00e9bb, a Tit\u00e1n szinte g\u00f6mb alak\u00fa, ak\u00e1r egy futball-labda. Amikor a hold a Szaturnuszhoz legk\u00f6zelebb van, megny\u00falik, \u00edgy ink\u00e1bb egy r\u00f6gbi-labd\u00e1ra hasonl\u00edt.<\/p>\n

Az ebb\u0151l ered\u0151 \u00e1rap\u00e1ly hat\u00e1s\u00e1ra a Tit\u00e1n felsz\u00edne t\u00f6bb mint 10 m\u00e9terrel emelkedik \u00e9s s\u00fcllyed. Ez a szintv\u00e1ltoz\u00e1s azonban j\u00f3val nagyobb, mint amire sz\u00e1m\u00edtani lehetne, ha a hold teljes eg\u00e9sz\u00e9ben szil\u00e1rd lenne. Ez arra utal, hogy a mintegy 50 km vastag j\u00e9gh\u00e9j alatt egy felsz\u00edn alatti \u00f3ce\u00e1n tal\u00e1lhat\u00f3, amelynek m\u00e9lys\u00e9ge ak\u00e1r 250 km is lehet.<\/p>","protected":false},"excerpt":{"rendered":"
