Titan este mai mare dec\u00e2t planeta Mercur. De asemenea, este a doua lun\u0103 ca m\u0103rime din Sistemul Solar \u0219i singura lun\u0103 cu o atmosfer\u0103 dens\u0103. La fel ca pe P\u0103m\u00e2nt, gazul principal este azotul, dar pe Titan este mult mai rece. Suprafa\u021ba sa este \u00eenghe\u021bat\u0103 la minus 180 de grade Celsius. Dac\u0103 s-ar \u00eenc\u0103lzi, Titan ar putea s\u0103 sus\u021bin\u0103 via\u021ba.<\/p>\n<\/div>\n

P\u00e2n\u0103 la sosirea sondei spa\u021biale Cassini-Huygens a NASA \u0219i ESA \u00een 2004, se \u0219tiau foarte pu\u021bine lucruri despre Titan. Suprafa\u021ba sa este ascuns\u0103 sub un strat gros de nori portocalii.<\/p>\n

La 14 ianuarie 2005, sonda Huygens a Agen\u021biei Spa\u021biale Europene (ESA) a efectuat o aterizare istoric\u0103 pe Titan. \u00cen timpul cobor\u00e2rii sale, care a durat dou\u0103 ore \u0219i jum\u0103tate, Huygens a fost \u00eempins\u0103 spre est de v\u00e2nturi de la altitudine mare, cu viteze de peste 100 km pe or\u0103. V\u00e2nturile \u0219i-au schimbat direc\u021bia la o \u00een\u0103l\u021bime de 7 km, purt\u00e2nd sonda Huygens u\u0219or spre vest \u00een ultimele minute ale cobor\u00e2rii. Huygens a descoperit un peisaj \u00eenghe\u021bat, marcat de canale \u00eentunecate care \u0219erpuiau spre o \u2018linie de \u021b\u0103rm\u2019 neted\u0103.<\/p>\n

Atmosfera lui Titan con\u021bine aproximativ 5% metan. Interac\u021biunea razelor solare cu metanul d\u0103 na\u0219tere unei ce\u021bi dense de culoare portocalie. (Pe P\u0103m\u00e2nt, metanul este ars \u00een cazane \u0219i aragaze.) Uneori, furtunile de metan umplu canalele uscate, cre\u00e2nd r\u00e2uri temporare care erodeaz\u0103 suprafa\u021ba \u0219i transport\u0103 materialul af\u00e2nat c\u0103tre c\u00e2mpiile din apropiere.<\/p>\n

\u00cen cursul celor peste 70 de survoluri ale lui Titan, instrumentele radar \u0219i cu infraro\u0219u ale sondei Cassini au cartografiat o mare parte a suprafe\u021bei. Acestea au descoperit numeroase caracteristici ciudate, printre care dune uria\u0219e de nisip din hidrocarburi, lan\u021buri muntoase, lacuri de metan \u0219i posibili vulcani de ghea\u021b\u0103. (Hidrocarburile sunt compuse din hidrogen \u0219i carbon. Exemple pe P\u0103m\u00e2nt sunt c\u0103rbunele, funinginea \u0219i gudronul.)<\/p>","protected":false},"excerpt":{"rendered":"
