RTBF – Mardi 13 septembre – 07:25 >> L’invit\u00e9 science – soci\u00e9t\u00e9 fut Emmanuel Jehin<\/strong> interview\u00e9 par Sophie Brems.<\/p>\n

Th\u00e8me de la s\u00e9quence scientifique de ce jour est l’explosion cosmique la plus lointaine jamais observ\u00e9e ouvre une nouvelle fen\u00eatre sur l’enfance de notre univers et la formation des \u00e9toiles, ont estim\u00e9 lundi des astrophysiciens am\u00e9ricains.<\/p>\n

Le satellite am\u00e9ricain Swift et des \u00e9quipes d’astronomes italiens et japonais ont pu d\u00e9tecter et mesurer le 4 septembre avec des t\u00e9l\u00e9scopes terrestres cette giganteste d\u00e9flagration qui a produit un jaillissement de rayons gamma, ont annonc\u00e9 la Nasa et des astrophysiciens am\u00e9ricains. \u00ab\u00a0Il s’agit de tr\u00e8s loin de l’explosion d’une \u00e9toile la plus \u00e9loign\u00e9e dans le cosmos\u00a0\u00bb \u00e0 environ 12,6 milliards d’ann\u00e9es lumi\u00e8re, moins d’un milliard d’ann\u00e9es apr\u00e8s la naissance de l’univers, a expliqu\u00e9 l’astrophysicien Don Lamb, de l’universit\u00e9 de Chicago (nord), lors d’une conf\u00e9rence de presse. Les scientifiques estiment que l’univers est n\u00e9 il y a environ 13,5 milliards d’ann\u00e9e \u00e0 la suite du Big Bang. Jusqu’alors, l’explosion la plus lointaine avait \u00e9t\u00e9 observ\u00e9e \u00e0 12,2 milliards d’ann\u00e9es-lumi\u00e8re. Une ann\u00e9e-lumi\u00e8re correspond \u00e0 la distance parcourue par la lumi\u00e8re pendant un an \u00e0 savoir 10.000 milliards de km.<\/p>\n\n\n
