Et cette simple affirmation vient mettre un vrai bazar dans les connaissances qu\u2019ont les astronomes du syst\u00e8me solaire.<\/p>\n<p>Que dit cette publication exactement ?<br \/>\nElle livre deux informations tr\u00e8s importantes.<\/p>\n<p>La premi\u00e8re concerne la masse totale des anneaux qui a pu \u00eatre calcul\u00e9e avec une pr\u00e9cision in\u00e9gal\u00e9e un peu comme si les scientifiques les avaient d\u00e9pos\u00e9s directement sur une balance. On sait donc d\u00e9sormais qu\u2019ils ont une masse de 15,4 milliards de milliards de kilogrammes. Cela peut vous sembler beaucoup mais il n\u2019en est rien. Et ce chiffre va faire son entr\u00e9e dans les encyclop\u00e9dies.<br \/>\nLa deuxi\u00e8me information soul\u00e8ve beaucoup plus de questions, elle indique qu\u2019en raison de cette faible masse, les anneaux de Saturne pourraient avoir \u00e9t\u00e9 form\u00e9s r\u00e9cemment <strong>il y a \u00ab seulement \u00bb quelques centaines de millions d\u2019ann\u00e9es.<\/strong> Constitu\u00e9s \u00e0 99\u202f% de glace ils n\u2019ont attir\u00e9 que 1% de d\u00e9bris, signe de leur jeunesse.<br \/>\nJusqu\u2019\u00e0 maintenant, <strong>on pensait que les anneaux remontaient \u00e0 la formation du syst\u00e8me solaire il y a 4,5 milliards d\u2019ann\u00e9es<\/strong>.
