\"outters-nicolas\"Voici un bel amas dans la chevelure de B\u00e9r\u00e9nice distant de 323 millions d’ann\u00e9es lumi\u00e8res et qui d\u00e9nombre un bon millier de galaxies.
\nJe vous conseille d’aller voir la full et de vous adapter \u00e0 la p\u00e9nombre.
\nVous remarquerez \u00e9galement quelques extensions de mati\u00e8res assez \u00e9tranges je dois dire.<\/p>\n<\/div>
