Titan je v\u011bt\u0161\u00ed ne\u017e planeta Merkur. Je to tak\u00e9 druh\u00fd nejv\u011bt\u0161\u00ed m\u011bs\u00edc ve slune\u010dn\u00ed soustav\u011b a jedin\u00fd m\u011bs\u00edc s hustou atmosf\u00e9rou. Stejn\u011b jako na Zemi je hlavn\u00edm plynem dus\u00edk, ale na Titanu je mnohem chladn\u011bji. Jeho povrch je zmrzl\u00fd na teplotu minus 180 stup\u0148\u016f Celsia. Kdyby se oteplil, mohl by Titan podporovat \u017eivot.<\/p>\n<\/div>\n

A\u017e do p\u0159\u00edletu sondy Cassini-Huygens (spole\u010dn\u00fd projekt NASA a ESA) v roce 2004 se o Titanu v\u011bd\u011blo jen velmi m\u00e1lo. Jeho povrch je skryt pod hustou vrstvou oran\u017eov\u00fdch mrak\u016f.<\/p>\n

14. ledna 2005 provedla sonda Huygens agentury ESA historick\u00e9 p\u0159ist\u00e1n\u00ed na Titanu. B\u011bhem sv\u00e9ho 2\u00bdhodinov\u00e9ho sestupu byla sonda Huygens un\u00e1\u0161ena v\u00fdchodn\u00edm sm\u011brem vysokohorsk\u00fdmi v\u011btry o rychlosti p\u0159esahuj\u00edc\u00ed 100 km za hodinu. Ve v\u00fd\u0161ce 7 km se sm\u011br v\u011btru obr\u00e1til a v posledn\u00edch minut\u00e1ch sestupu nesl Huygens jemn\u011b sm\u011brem na z\u00e1pad. Huygens objevil ledovou krajinu, kterou prot\u00ednaly tmav\u00e9 kan\u00e1ly vinouc\u00ed se sm\u011brem k hladk\u00e9mu \u2018pob\u0159e\u017e\u00ed\u2019.<\/p>\n

Atmosf\u00e9ra Titanu obsahuje p\u0159ibli\u017en\u011b 5 procent metanu. P\u016fsoben\u00edm slune\u010dn\u00edho z\u00e1\u0159en\u00ed na metan vznik\u00e1 hust\u00fd oran\u017eov\u00fd opar. (Na Zemi se metan spaluje v kotl\u00edch a spor\u00e1c\u00edch.) Metanov\u00e9 bou\u0159e n\u011bkdy zapln\u00ed vyschl\u00e9 koryta a vytvo\u0159\u00ed do\u010dasn\u00e9 \u0159eky, kter\u00e9 eroduj\u00ed povrch a odn\u00e1\u0161ej\u00ed sypk\u00fd materi\u00e1l na nedalek\u00e9 pl\u00e1n\u011b.<\/p>\n

B\u011bhem v\u00edce ne\u017e 70 p\u0159elet\u016f kolem Titanu zmapovaly radarov\u00e9 a infra\u010derven\u00e9 p\u0159\u00edstroje sondy Cassini velkou \u010d\u00e1st jeho povrchu. Objevily mnoho podivn\u00fdch \u00fatvar\u016f, v\u010detn\u011b obrovsk\u00fdch dun z uhlovod\u00edkov\u00e9ho p\u00edsku, horsk\u00fdch h\u0159eben\u016f, metanov\u00fdch jezer a mo\u017en\u00fdch ledov\u00fdch sopek. (Uhlovod\u00edky se skl\u00e1daj\u00ed z vod\u00edku a uhl\u00edku. P\u0159\u00edklady na Zemi jsou uhl\u00ed, saze a dehet.)<\/p>","protected":false},"excerpt":{"rendered":"
