Africa-Press – Djibouti. <\/strong><\/span>L’Agence spatiale europ\u00e9enne et la Nasa ont publi\u00e9 une nouvelle photo prise par le t\u00e9lescope James Webb, montrant la Galaxie du Fant\u00f4me, situ\u00e9e \u00e0 environ 32 millions d’ann\u00e9es-lumi\u00e8re de la Terre.<\/p>\n

Le t\u00e9lescope spatial James Webb a capt\u00e9 de nouveaux d\u00e9tails d’une galaxie, dite du Fant\u00f4me, dans une image spectaculaire montrant sa forme de spirale publi\u00e9e par l’Agence spatiale europ\u00e9enne (ESA) et la Nasa.<\/p>\n

Lanc\u00e9 dans l’espace fin 2021 et op\u00e9rationnel depuis juillet, James Webb a depuis r\u00e9v\u00e9l\u00e9 d’impressionnantes images de Jupiter, de n\u00e9buleuses et d’autres galaxies lointaines, fournissant aux scientifiques quantit\u00e9 de donn\u00e9es in\u00e9dites \u00e0 analyser.<\/p>\n

Celle publi\u00e9e lundi 29 ao\u00fbt montre M74, ou la Galaxie du Fant\u00f4me, son c\u0153ur bleu vif et son impeccable spirale, observ\u00e9e par l’instrument MIRI, qui \u00e9tudie l’infrarouge moyen et est le fruit d’une collaboration entre Europ\u00e9ens et Am\u00e9ricains.<\/p>\n

\u00ab\u00a0Le regard per\u00e7ant de Webb a r\u00e9v\u00e9l\u00e9 de fins filaments de gaz et de poussi\u00e8re dans les bras lumineux en forme de spirale qui se d\u00e9ploient du centre de cette image\u00a0\u00bb, note sur son site l’ESA, qui pr\u00e9cise que la galaxie avait d\u00e9j\u00e0 \u00e9t\u00e9 observ\u00e9e par le mythique t\u00e9lescope spatial Hubble, lanc\u00e9 en 1990 et toujours en fonctionnement.<\/p>\n

\u00ab\u00a0Identifier les r\u00e9gions de la galaxie o\u00f9 se forment des \u00e9toiles\u00a0\u00bb<\/b><\/p>\n

L’agence europ\u00e9enne, qui a co-d\u00e9velopp\u00e9 le t\u00e9lescope avec la Nasa, note \u00e9galement qu’un \u00ab\u00a0manque de gaz\u00a0\u00bb permet d’avoir une vision plus claire des \u00e9toiles du centre de la galaxie, situ\u00e9e \u00e0 environ 32 millions d’ann\u00e9es-lumi\u00e8re dans la constellation des Poissons.<\/p>\n

Les donn\u00e9es collect\u00e9es \u00ab\u00a0vont permettre aux astronomes d’identifier les r\u00e9gions de la galaxie o\u00f9 se forment des \u00e9toiles, mesurer avec finesse la masse et l’\u00e2ge des amas d’\u00e9toiles et mieux conna\u00eetre la nature des petits grains de poussi\u00e8re qui d\u00e9rivent dans l’espace interstellaire\u00a0\u00bb, note encore l’ESA.<\/p>\n

Bijou d’ing\u00e9nierie d’une valeur de 10 milliards de dollars, le t\u00e9lescope James Webb m\u00e8ne ses observations \u00e0 1,5 million de kilom\u00e8tres de la Terre.<\/p>\n

Il a, pour la premi\u00e8re fois, d\u00e9tect\u00e9 la pr\u00e9sence de CO2 dans l’atmosph\u00e8re d’une exoplan\u00e8te, c’est-\u00e0-dire une plan\u00e8te en dehors de notre syst\u00e8me solaire, avaient annonc\u00e9 des chercheurs la semaine pass\u00e9e.<\/p>\n
