Africa-Press – Madagascar. <\/strong><\/span>Ces images ont e\u0301te\u0301 prises afin de ve\u0301rifier le fonctionnement des instruments scientifiques et de les calibrer. Elles ne sont donc pas encore repre\u0301sentatives des capacite\u0301s finales du te\u0301lescope. Mais elles indiquent d\u2019ores et de\u0301ja\u0300 que le te\u0301lescope spatiale Euclid sera capable de remplir ses objectifs, a de\u0301clare\u0301 dans un communique\u0301 l\u2019agence spatiale europe\u0301enne (ESA). \u201cApre\u0300s plus de 11 ans a\u0300 concevoir et de\u0301velopper Euclid, il est grisant et tre\u0300s e\u0301mouvant de voir ces premie\u0300res images\u201d, a de\u0301clare\u0301 Giuseppe Racca, responsable de la mission Euclid a\u0300 l\u2019ESA. \u201cUne fois entie\u0300rement calibre\u0301, Euclid observera des milliards de galaxies pour cre\u0301er la plus grande carte en 3D du ciel jamais re\u0301alise\u0301e.\u201d<\/p>\n

Les premie\u0300res images d\u2019Euclid \u201ccontamine\u0301es\u201d par une source de lumie\u0300re inattendue<\/b><\/p>\n

Apre\u0300s avoir de\u0301colle\u0301 depuis la Floride le 1er juillet 2023, le te\u0301lescope europe\u0301en, auquel la Nasa a e\u0301galement participe\u0301, a voyage\u0301 jusqu\u2019a\u0300 sa destination situe\u0301e a\u0300 environ 1,5 million de kilome\u0300tres de la Terre. Euclid a deux instruments embarque\u0301s: un imageur observant en lumie\u0300re visible (VIS), et un spectrome\u0300tre observant dans l\u2019infrarouge proche (NISP). Le premier doit de\u0301terminer la forme pre\u0301cise des galaxies, le second leur distance. Mais lorsqu\u2019ils ont e\u0301te\u0301 mis en marche, les scientifiques ont eu une grosse frayeur : les images e\u0301taient \u201ccontamine\u0301es\u201d par une source de lumie\u0300re inattendue, a de\u0301clare\u0301 l\u2019ESA.<\/p>\n

Des recherches sur la cause du proble\u0300me ont \u201cindique\u0301 que la lumie\u0300re du Soleil s\u2019infiltrait dans le vaisseau, probablement par une petite ouverture\u201d, a explique\u0301 l\u2019agence europe\u0301enne. Or, pour de\u0301tecter la faible lumie\u0300re de lointaines galaxies, la lumie\u0300re e\u0301clatante de notre Soleil (auquel Euclid fait dos), doit absolument e\u0302tre bloque\u0301e. \u201cEn tournant Euclid, les e\u0301quipes ont re\u0301alise\u0301 que cette lumie\u0300re n\u2019e\u0301tait de\u0301tecte\u0301e qu\u2019a\u0300 certaines orientations, donc en e\u0301vitant certains angles, l\u2019instrument VIS sera capable de re\u0301aliser sa mission\u201d, a assure\u0301 l\u2019ESA.<\/p>\n

Les ope\u0301rations scientifiques du te\u0301lescope Euclid doivent commencer dans 2 mois<\/b><\/p>\n

La matie\u0300re noire et l\u2019e\u0301nergie sombre constituent 95% de l\u2019Univers, mais leur nature reste un grand myste\u0300re pour les scientifiques. Quand la premie\u0300re assure la cohe\u0301sion des galaxies, l\u2019e\u0301nergie sombre provoque elle l\u2019expansion de l\u2019Univers. Gra\u0302ce a\u0300 sa carte en 3D, le te\u0301lescope permettra des mesures pre\u0301cises sur la distribution des galaxies et l\u2019expansion de l\u2019Univers, qui aurait de\u0301marre\u0301 il y a six milliards d\u2019anne\u0301es. Les galaxies lointaines observe\u0301es permettront de remonter le temps jusqu\u2019a\u0300 il y a 10 milliards d\u2019anne\u0301es \u2013 la dure\u0301e ne\u0301cessaire pour que leur lumie\u0300re nous parvienne. L\u2019espoir est qu\u2019Euclid puisse ainsi de\u0301celer les traces laisse\u0301es par la matie\u0300re noire et l\u2019e\u0301nergie sombre au fil de la formation des galaxies. Les ope\u0301rations scientifiques du te\u0301lescope doivent commencer dans environ deux mois.<\/p>\n
