Nu, efter en grundig analyse af dataene fra Huygens, har forskerne afd\u00e6kket mange af mysterierne omkring denne m\u00e5ne, der er p\u00e5 st\u00f8rrelse med en planet.<\/p>\n<\/div>\n<p>Under det 2\u00bd timer lange fald registrerede instrumenterne oplysninger om temperatur, vindhastighed og atmosf\u00e6rens sammens\u00e6tning. Resultaterne viser, at Huygens havde en uj\u00e6vn rejse, da den blev bl\u00e6st mod \u00f8st af h\u00f8jtliggende vinde p\u00e5 over 100 km i timen. Men i takt med at den drev nedad gennem den orange t\u00e5ge, steg temperaturen og atmosf\u00e6rens t\u00e6thed, mens vindhastigheden faldt. Vindene skiftede retning i en h\u00f8jde af 7 km og bar Huygens blidt mod vest i de sidste minutter af nedstigningen.<\/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>Placering af landingsstedet<\/figcaption><\/figure>\n<p>Atmosf\u00e6ren bestod hovedsageligt af nitrogen med ca. 5 procent metan, og t\u00e5gen i atmosf\u00e6ren bestod ogs\u00e5 hovedsageligt af metan.

Den finkornede is var gennemv\u00e6det af metan, som fordampede, da den varme sonde kom i ber\u00f8ring med den.<\/p>\n<nav class=\"related\" aria-label=\"Relateret\">\n<h2 class=\"related__heading\">Relateret<\/h2>\n<div class=\"grid related__grid\">\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"http:\/\/www.esa.int\/SPECIALS\/Kids_Comic\/index.html\" target=\"_blank\" rel=\"noopener\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">comic_episode03_strillo<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<\/div>\n<\/nav>","protected":false},"excerpt":{"rendered":"<p>On 14 January 2005 ESA&#8217;s Huygens probe made an historic landing on the surface of Saturn&#8217;s giant satellite, Titan.
