Maad nimetatakse sageli siniseks planeediks, sest see on meie P\u00e4ikeses\u00fcsteemis ainus maailm, mida suures osas katab vesi. Siiski arvatakse, et mitmete satelliitide, sealhulgas Saturni hiiglasliku kuu Titani, pinna all asuvad ookeanid. Titani pinnal\u00e4hedase ookeani olemasolu viitab suurte loodete avastamisele.<\/p>\n<\/div>\n

Iga\u00fcks, kes k\u00fclastab rannikut, on tuttav loodetega \u2013 merepinna t\u00f5usu ja langusega kaks korda p\u00e4evas. V\u00e4hem silmatorkavad on loodetega sarnased n\u00e4htused, mis p\u00f5hjustavad meie planeedi maakoore t\u00f5usu ja langust m\u00f5ne k\u00fcmne sentimeetri v\u00f5rra. Neid n\u00e4htusi p\u00f5hjustab Kuu ja P\u00e4ikese \u00fchine gravitatsiooniline m\u00f5ju Maale. Titanil tekivad lood samamoodi. Kuid seekord on see Saturni gravitatsioonij\u00f5ud, mis paneb kuu kuju muutuma selle 16-p\u00e4evase orbiidi jooksul \u00fcmber planeedi.<\/p>\n

Titani kuju muutumist on tuvastatud, j\u00e4lgides hoolikalt kosmosesondi Cassini trajektoori, kui see lendab kuu l\u00e4hedalt m\u00f6\u00f6da. Erinevused selles, kuidas Titan Cassinit m\u00f5jutas, n\u00e4itasid, et kuu gravitatsioonij\u00f5ud \u2013 ja seega ka selle kuju \u2013 oli v\u00e4ga veidi muutunud. K\u00f5ige kaugemal punktis, kus Saturni gravitatsioon on n\u00f5rgem, on Titan peaaegu kerakujuline, nagu jalgpall. Kui satelliit on Saturnile k\u00f5ige l\u00e4hemal, venib see v\u00e4lja nii, et muutub pigem ragbipalli sarnaseks.<\/p>\n

Sellest tulenevad loodete m\u00f5jud p\u00f5hjustavad Titani pinna t\u00f5usu ja langust rohkem kui 10 meetri v\u00f5rra. See k\u00f5ikumine on aga palju suurem, kui v\u00f5iks eeldada, kui kuu oleks l\u00e4bivalt tahke. See viitab sellele, et umbes 50 km paksuse j\u00e4\u00e4koore all asub pinnal\u00e4hedane ookean, mille s\u00fcgavus v\u00f5ib olla 250 km.<\/p>","protected":false},"excerpt":{"rendered":"
