Situ\u00e9 dans le d\u00e9sert d\u2019Atacama, pr\u00e8s de la ville chilienne de San Pedro de Atacama, le plateau de Chajnantor est l’endroit id\u00e9al pour installer un interf\u00e9rom\u00e8tre comme ALMA : \u00e0 5000 m d’altitude, il se trouve au-dessus de 50 % de l\u2019atmosph\u00e8re terrestre, l\u00e0 o\u00f9 la quantit\u00e9 de vapeur d’eau est 10 \u00e0 1.000 fois plus faible qu\u2019au niveau de la mer.<\/p>\n

Inaugur\u00e9 en mars 2013 apr\u00e8s plus de 10 ans de travaux et un budget de 1,4 milliard de dollars, ALMA devrait permettre d’atteindre une r\u00e9solution d’environ 0,005 seconde d’arc lorsqu’il sera totalement op\u00e9rationnel. Il pourra ainsi observer en d\u00e9tail des objets c\u00e9lestes lointains beaucoup mieux que ne le fait le t\u00e9lescope spatial Hubble<\/a>.<\/p>\n
