Zdaj, po temeljiti analizi podatkov sonde Huygens, so znanstveniki razkrili \u0161tevilne skrivnosti tega lune, velike kot planet.<\/p>\n<\/div>\n<p>Med 2,5-urnim spustom so instrumenti bele\u017eili podatke o temperaturi, hitrosti vetra in sestavi atmosfere. Rezultati ka\u017eejo, da je imel Huygens burno potovanje, saj so ga vetrovi v vi\u0161ini ve\u010d kot 100 km na uro ponesli proti vzhodu. Vendar sta se med spu\u0161\u010danjem skozi oran\u017eno meglico temperatura in gostota atmosfere pove\u010dali, hitrost vetra pa zmanj\u0161ala. Na vi\u0161ini 7 km so vetrovi spremenili smer in so Huygensa v zadnjih minutah spu\u0161\u010danja ne\u017eno ponesli proti zahodu.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"400\" data-credit=\"NASA\/JPL\/Space Science Institute\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2005\/11\/Location_of_landing_site2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2005\/11\/location_of_landing_site2\/17904712-2-eng-GB\/Location_of_landing_site.jpg\" alt=\"Location of landing site\"><figcaption>Lokacija pristajali\u0161\u010da<\/figcaption><\/figure>\n<p>Atmosfera je bila v glavnem sestavljena iz du\u0161ika, z okoli 5 odstotki metana, tudi megla v atmosferi pa je bila v glavnem sestavljena iz metana.
