Lanc\u00e9 l\u2019an dernier depuis Cap Canaveral \u00e0 bord d'une fus\u00e9e Falcon 9 de SpaceX<\/a>, le t\u00e9lescope spatial Euclide<\/strong> repr\u00e9sente une avanc\u00e9e majeure dans l'exploration cosmique. D\u00e9di\u00e9 \u00e0 d\u00e9mystifier les zones d'ombre de l'univers, notamment les myst\u00e8res de l'\u00e9nergie noire<\/strong> et de la mati\u00e8re noire<\/strong>, il a rapidement prouv\u00e9 son potentiel en capturant des vues spectaculaires de l'univers surprenantes<\/a>.<\/p>\n

Malgr\u00e9 ce d\u00e9part prometteur, la mission d'Euclide a \u00e9t\u00e9 confront\u00e9e \u00e0 un probl\u00e8me technique impr\u00e9vu<\/strong>. Des accumulations de glace<\/strong> extr\u00eamement fines se sont form\u00e9es sur les miroirs du t\u00e9lescope<\/strong>, r\u00e9duisant sa capacit\u00e9 \u00e0 collecter la lumi\u00e8re. Cette glace, bien qu'\u00e0 peine plus \u00e9paisse qu'un filament d'ADN, a engendr\u00e9 une baisse graduelle mais significative de son efficacit\u00e9, mena\u00e7ant la pr\u00e9cision et la qualit\u00e9 des observations.<\/p>\n
