L\u2019organisation Square Kilometre Array Observatory\u00a0(SKAO) construit actuellement l\u2019un des projets scientifiques les plus ambitieux au monde\u00a0: un gigantesque r\u00e9seau de radiot\u00e9lescopes r\u00e9parti entre l\u2019Afrique du Sud et l\u2019Australie. Une fois achev\u00e9, cet ensemble d\u2019antennes et paraboles sera le plus puissant jamais con\u00e7u et permettra d\u2019observer les premi\u00e8res \u00e9toiles et galaxies form\u00e9es apr\u00e8s le Big Bang, il y a plus de 13\u00a0milliards d\u2019ann\u00e9es..<\/p>\n

Dans le d\u00e9sert du Karoo, en Afrique du Sud<\/a>, des dizaines d\u2019antennes paraboliques blanches<\/a> \u00e9mergent d\u2019un paysage aride et silencieux. Le village le plus proche, Carnarvon, se situe \u00e0 environ 80\u00a0km. Ici, toute interf\u00e9rence humaine est strictement contr\u00f4l\u00e9e\u00a0: les t\u00e9l\u00e9phones portables sont interdits et chaque appareil \u00e9lectronique doit \u00eatre test\u00e9 et approuv\u00e9 avant d\u2019\u00eatre utilis\u00e9. Un environnement essentiel pour capter des signaux<\/a> radio extr\u00eamement faibles venus de l\u2019espace.<\/p>\n

Nous construisons une installation capable de d\u00e9tecter des ondes radio d\u2019une sensibilit\u00e9 in\u00e9gal\u00e9e, afin de comprendre comment l\u2019univers s\u2019est…<\/p>\n
