LE CLEA communique :<\/strong><\/p>\n\n\n\n

Tous les journaux en parlent et il est difficile de l\u2019ignorer.<\/p>\n\n\n\n

Un ast\u00e9ro\u00efde en forme de cigare d\u2019environ 400 m de long  pour environ 40 m de large est pass\u00e9 \u00e0 30 millions de km de la Terre a une vitesse estim\u00e9e \u00e0 38 km\/s soit environ 136 000 km\/h.<\/p>\n\n\n\n

Cet objet fut d\u2019abord pris pour une com\u00e8te avant que l\u2019on \u00e9tablisse qu\u2019il s\u2019agissait en fait d\u2019un ast\u00e9ro\u00efde venu d\u2019un autre syst\u00e8me plan\u00e9taire que le n\u00f4tre.<\/p>\n\n\n\n

L\u2019UAI l\u2019a baptis\u00e9 A\/2017 U1a mais plus famili\u00e8rement il est d\u00e9sign\u00e9 par \u00ab Oumuamua \u00bb<\/em> ce qui signifierait en Hawa\u00efen : \u00ab messager venu de loin et arriv\u00e9 le premier \u00bb.<\/em><\/p>\n\n\n\n

Vous n\u2019aurez que l\u2019embarras du choix pour trouver des informations sur Internet.<\/p>\n\n\n\n

Je propose par exemple le site de Futura-sciences qui, apr\u00e8s pas mal de r\u00e9p\u00e9titions, donne la parole \u00e0 Michel Cass\u00e9 qui s\u2019exprime dans l\u2019amphi de l\u2019IAP \u00e0 l\u2019Observatoire de Paris.<\/p>\n\n\n\n
