15 jours de beau temps au mois de mai 2020 c’est exceptionnel ! r\u00e9sultat : une image de ciel tr\u00e8s profond, alors allez voir la full qui regorge de petites galaxie des amas de galaxie.<\/p>\n

Voici pour les puristes une version annotate assez compl\u00e8te.<\/p>\n

Le Superamas d’Hercule<\/b> (SCl 160<\/b>) d\u00e9signe deux1<\/a><\/sup> superamas de galaxies<\/a> situ\u00e9s dans la constellation \u00e9ponyme<\/a>.<\/p>\n

Par rapport aux autres superamas locaux, ceux d’Hercule semblent particuli\u00e8rement grands, d’une taille d’environ 330 millions d’al<\/a>. Juste \u00e0 c\u00f4t\u00e9 d’eux se situe un immense vide cosmique d’une taille \u00e9quivalente aux superamas2<\/a><\/sup>.<\/p>\n

La r\u00e9gion comprend les amas de galaxies<\/a> Abell 2147<\/a>, A2151<\/a> et A2152<\/a>3<\/a><\/sup>,<\/sup>4<\/a><\/sup>. On a \u00e9galement trouv\u00e9 un tr\u00e8s long filament de galaxies qui connecte ces groupes de galaxies avec la paire Abell 2197<\/a> et A2199<\/a>4<\/a><\/sup>.<\/strong><\/p>\n<\/div><\/div><\/div>
