Titan je ve\u010dji od planeta Merkurja. Je tudi drugi najve\u010dji satelit v Oson\u010dju in edini satelit z gosto atmosfero. Tako kot na Zemlji je glavni plin du\u0161ik, vendar je na Titanu precej hladneje. Na njegovi povr\u0161ini vlada globoka zmrzal pri minus 180 stopinjah Celzija. \u010ce bi se ogrelo, bi Titan morda lahko podpiral \u017eivljenje.<\/p>\n<\/div>\n

Do prihoda vesoljske sonde Cassini-Huygens, ki sta jo skupaj razvili NASA in ESA, leta 2004, je bilo o Titanu znanega le malo. Njegova povr\u0161ina je skrita pod debelo plastjo oran\u017enih oblakov.<\/p>\n

14. januarja 2005 je sonda Huygens agencije ESA izvedla zgodovinski pristanek na Titanu. Med 2\u00bd-urnim spustom so visokogorski vetrovi s hitrostjo ve\u010d kot 100 km na uro sondo Huygens odnesli proti vzhodu. Vetrovi so na vi\u0161ini 7 km spremenili smer in so Huygens v zadnjih minutah spusta ne\u017eno odnesli proti zahodu. Huygens je odkril ledeno pokrajino, zaznamovano s temnimi kanali, ki so se vijali proti gladki \u2018obali\u2019.<\/p>\n

Titanova atmosfera vsebuje pribli\u017eno 5 odstotkov metana. Son\u010dna svetloba, ki deluje na metan, ustvarja gosto oran\u017eno meglico. (Na Zemlji se metan uporablja kot gorivo v kotlih in kuhalnikih.) Metanske nevihte v\u010dasih napolnijo suhe kanale in ustvarijo za\u010dasne reke, ki erodirajo povr\u0161ino ter odna\u0161ajo razsuti material na bli\u017enje ravnice.<\/p>\n

Med ve\u010d kot 70 preleti ob Titana so Cassinijevi radarski in infrarde\u010di instrumenti kartirali velik del povr\u0161ine. Odkrili so \u0161tevilne nenavadne zna\u010dilnosti, med drugim ogromne sipine iz ogljikovodikovega peska, gorske verige, metanska jezera in morebitne ledeni vulkani. (Ogljikovodiki so sestavljeni iz vodika in ogljika. Primeri na Zemlji so premog, saj in katran.)<\/p>","protected":false},"excerpt":{"rendered":"
