AMAS GLOBULAIRE<\/h1>\n\n\n\n
C’est un amas stellaire contenant des milliers d’\u00e9toiles , de forme sph\u00e9rique , sa taille pouvant aller jusqu’\u00e0 plusieurs centaines d’ann\u00e9es lumi\u00e8re ( 1 al = 9 460 milliards de km ) . On compte environ 150 amas globulaires qui orbitent autour du centre de notre galaxie .
\nLa plupart de ces amas sont tr\u00e8s anciens , ils se sont probablement form\u00e9s en m\u00eame temps que leur galaxie .<\/p>\n\n\n\n
Ci-dessous l’amas globulaire M80 ( 80\u00e8me objet du catalogue Messier ) : <\/p>\n\n\n\n AMAS OUVERT Un amas ouvert est un amas stellaire groupant environ de 100 \u00e0 1 000 \u00e9toiles de m\u00eame \u00e2ge li\u00e9es entre elles par la gravitation . Ils naissent au sein des n\u00e9buleuses diffuses , ce sont des objets jeunes et peu lumineux . \u00c0 un niveau amateur ils sont observables dans notre galaxie .
