L\u2019exploration de l\u2019univers<\/strong> est une qu\u00eate permanente pour l\u2019humanit\u00e9, et les instruments spatiaux jouent un r\u00f4le essentiel dans cette aventure. Parmi eux, le t\u00e9lescope spatial europ\u00e9en Euclid<\/strong>, lanc\u00e9 en 2023, se distingue par sa mission ambitieuse : \u00e9clairer les myst\u00e8res de la mati\u00e8re noire et de l\u2019\u00e9nergie noire, des ph\u00e9nom\u00e8nes invisibles qui fa\u00e7onnent l\u2019univers. D\u00e8s ses premi\u00e8res images<\/a>, ce dernier a captur\u00e9 des galaxies<\/strong> et des \u00e9toiles<\/strong> \u00e0 des millions de kilom\u00e8tres de la Terre, marquant le d\u00e9but d\u2019une exploration prometteuse.<\/p>\n

Toutefois, la mission d\u2019Euclid<\/strong> a failli \u00eatre compromise en d\u00e9but d\u2019ann\u00e9e 2024. Le t\u00e9lescope a rencontr\u00e9 un probl\u00e8me majeur<\/a> : une accumulation de glace sur ses miroirs qui perturbait la qualit\u00e9 des images. \u00c0 1,6 million de kilom\u00e8tres de la Terre<\/strong>, cette panne aurait pu mettre fin \u00e0 ses observations. Mais gr\u00e2ce \u00e0 une intervention de l\u2019Agence Spatiale Europ\u00e9enne (ESA)<\/a>, ce dernier a \u00e9t\u00e9 d\u00e9givr\u00e9 avec succ\u00e8s. Restaur\u00e9, il est maintenant de retour et vient de d\u00e9voiler de nouvelles images \u00e9poustouflantes<\/strong>, relan\u00e7ant ainsi son projet de cartographie cosmique<\/strong>.<\/p>\n
