Abell 2065 est un amas de galaxies tr\u00e8s concentr\u00e9 dans la constellation de la Couronne bor\u00e9ale contenant plus de 400 galaxies membres, dont les plus brillantes sont de magnitude 16. L’amas est \u00e0 plus d’un milliard d’ann\u00e9es-lumi\u00e8re de la Terre.<\/p>\n<\/div><\/div><\/div>

Cela reste \u00e0 ce jour l’amas de galaxies le plus lointain que j’ai jamais shoot\u00e9.<\/p>\n

1 milliard d’ann\u00e9e lumi\u00e8re de distance. Je me suis amus\u00e9 \u00e0 demander \u00e0 Mistral IA de me calculer combien cela faisait de voyages vers la lune depuis la terre :<\/p>\n

Voici la r\u00e9ponse de Mistral IA :<\/p>\n

1. Voyage Terre-Lune<\/strong><\/h3>\n
    \n
  • Distance moyenne Terre-Lune<\/strong> : ~384 400 km.<\/li>\n
  • 1 milliard d’ann\u00e9es-lumi\u00e8re<\/strong> \u00e9quivaut \u00e0 environ 2,5 \u00d7 10\u00b9\u2079<\/strong> allers-retours Terre-Lune.<\/li>\n<\/ul>\n
    \n

    2. Voyage Terre-Proxima Centauri (\u00e9toile la plus proche)<\/strong><\/h3>\n
      \n
    • Distance Terre-Proxima Centauri<\/strong> : ~4,24 ann\u00e9es-lumi\u00e8re.<\/li>\n
    • 1 milliard d’ann\u00e9es-lumi\u00e8re<\/strong> \u00e9quivaut \u00e0 environ 235 millions<\/strong> de trajets Terre-Proxima Centauri.<\/li>\n<\/ul>\n
      \n

      Pour aller plus loin<\/strong><\/h3>\n
        \n
      • 1 ann\u00e9e-lumi\u00e8re<\/strong> \u2248 9 461 milliards de km.<\/li>\n<\/ul>\n
          \n
        • 1 milliard d’ann\u00e9es-lumi\u00e8re<\/strong> \u2248 9,461 \u00d7 10\u00b2\u00b9 km.<\/li>\n<\/ul>\n

          C\u2019est une distance si immense qu\u2019elle d\u00e9passe l\u2019\u00e9chelle humaine ! Si tu veux d\u2019autres comparaisons ou des d\u00e9tails, n\u2019h\u00e9site pas.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":11239,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"image","meta":{"footnotes":""},"categories":[109,120,126,147,152,367,504,700],"tags":[706],"class_list":["post-11240","post","type-post","status-publish","format-image","has-post-thumbnail","hentry","category-amas-de-galaxies","category-lrgb","category-observatoire-dorange","category-abell","category-toutes-categories","category-telescope-newton-16-skyvision","category-favorites","category-saison-2026","tag-abell-2065","post_format-post-format-image"],"_links":{"self":[{"href":"https:\/\/www.outters.fr\/index.php?rest_route=\/wp\/v2\/posts\/11240","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.outters.fr\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.outters.fr\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.outters.fr\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.outters.fr\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=11240"}],"version-history":[{"count":3,"href":"https:\/\/www.outters.fr\/index.php?rest_route=\/wp\/v2\/posts\/11240\/revisions"}],"predecessor-version":[{"id":11244,"href":"https:\/\/www.outters.fr\/index.php?rest_route=\/wp\/v2\/posts\/11240\/revisions\/11244"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.outters.fr\/index.php?rest_route=\/wp\/v2\/media\/11239"}],"wp:attachment":[{"href":"https:\/\/www.outters.fr\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=11240"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.outters.fr\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=11240"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.outters.fr\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=11240"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
