Nu, efter en noggrann analys av data fr\u00e5n Huygens, har forskarna lyckats l\u00f6sa m\u00e5nga av mysterierna kring denna m\u00e5ne som \u00e4r lika stor som en planet.<\/p>\n<\/div>\n<p>Under den 2\u00bd timmar l\u00e5nga nedstigningen registrerade instrumenten uppgifter om temperatur, vindhastighet och atmosf\u00e4rens sammans\u00e4ttning. Resultaten visar att Huygens fick en skakig resa d\u00e5 den drevs \u00f6sterut av vindar p\u00e5 h\u00f6g h\u00f6jd med hastigheter p\u00e5 \u00f6ver 100 km per timme. Men n\u00e4r den drev ned\u00e5t genom det orangea diset \u00f6kade atmosf\u00e4rens temperatur och densitet, samtidigt som vindhastigheten minskade.
