N\u00e5, etter en grundig analyse av dataene fra Huygens, har forskerne avdekket mange av mysteriene rundt denne m\u00e5nen, som er p\u00e5 st\u00f8rrelse med en planet.<\/p>\n<\/div>\n<p>Under den 2 \u00bd timer lange nedstigningen registrerte instrumentene data om temperatur, vindhastighet og atmosf\u00e6rens sammensetning. Resultatene viser at Huygens hadde en urolig tur, da den ble bl\u00e5st \u00f8stover av h\u00f8ytliggende vinder p\u00e5 over 100 km i timen. Men etter hvert som den drev ned gjennom den oransje disen, \u00f8kte temperaturen og tettheten i atmosf\u00e6ren, og vindhastigheten avtok. Vindene skiftet retning i en h\u00f8yde p\u00e5 7 km og f\u00f8rte Huygens forsiktig vestover i de siste minuttene av 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>Plassering av landingsstedet<\/figcaption><\/figure>\n<p>Atmosf\u00e6ren besto hovedsakelig av nitrogen, med omtrent 5 prosent metan, og t\u00e5ken i atmosf\u00e6ren besto ogs\u00e5 hovedsakelig av metan.
