Titan on suurem kui planeet Merkuur. Samuti on see P\u00e4ikeses\u00fcsteemi suuruselt teine kuu ja ainus kuu, millel on tihe atmosf\u00e4\u00e4r. Nii nagu Maalgi, on peamine gaas l\u00e4mmastik, kuid Titan on palju k\u00fclmem. Selle pind on s\u00fcgavas k\u00fclmas \u2013 miinus 180 kraadi Celsiuse j\u00e4rgi. Kui seal muutuks soojemaks, v\u00f5iks Titanil olla elu v\u00f5imalik.<\/p>\n<\/div>\n

Kuni NASA ja ESA \u00fchisprojekti \u201eCassini-Huygens\u201d kosmosesondi saabumiseni 2004. aastal teati Titani kohta v\u00e4ga v\u00e4he. Selle pind on peidetud paksu oran\u017ei pilvkatte alla.<\/p>\n

14. jaanuaril 2005 sooritas ESA sond Huygens ajaloolise maandumise Titanil. 2\u00bd-tunnise langemise jooksul kandisid k\u00f5rgel asuvad tuuled, mille kiirus \u00fcletas 100 km tunnis, Huygensi ida suunas. 7 km k\u00f5rgusel muutus tuule suund ning viis Huygensi langemise viimaste minutite jooksul \u00f5rnalt l\u00e4\u00e4ne poole. Huygens avastas j\u00e4ise maastiku, mida iseloomustasid tumedad kanalid, mis looklesid sujuvale \u2018rannajoonele\u2019 suunas.<\/p>\n

Titani atmosf\u00e4\u00e4r koosneb umbes 5 protsendist metaanist. P\u00e4ikesevalguse m\u00f5jul metaanile tekib paks oran\u017e udu. (Maal kasutatakse metaani k\u00fcttekateldes ja pliitidel.) Metaanist koosnevad vihmasajud t\u00e4idavad m\u00f5nikord kuivad kanalid, tekitades ajutisi j\u00f5gesid, mis kulutavad pinda ja kannavad lahtist materjali l\u00e4hedalasuvatele tasandikele.<\/p>\n

Rohkem kui 70 Titani m\u00f6\u00f6dalennu jooksul on Cassini radari- ja infrapunaseadmed kaardistanud suure osa planeedi pinnast. Nad on avastanud palju kummalisi objekte, sealhulgas hiiglaslikke s\u00fcsivesinikust liivast koosnevaid luiteid, m\u00e4eahelikke, metaanij\u00e4rvi ja v\u00f5imalikke j\u00e4\u00e4vulkaane. (S\u00fcsivesinikud koosnevad vesinikust ja s\u00fcsinikust. Maal on nende n\u00e4ideteks kivis\u00fcsi, tahm ja t\u00f5rv.)<\/p>","protected":false},"excerpt":{"rendered":"
