L'âge d'un grand nombre d'amas globulaires de la Voie Lactée est encore mal connu, la majorité des amas globulaires n'ont en fait pas de mesures d'âge cohérentes. Une équipe américaine vient d'évaluer l'âge de neuf amas globulaires qui sont situés à l'intérieur de notre galaxie. Ils déterminent un âge en relatif à d'autre amas globulaires dont les caractéristiques sont mieux connues. Ils trouvent pour les neuf amas étudiés un âge très élevé, en moyenne 12,9 milliards d'années. L'étude est parue dans The Astronomical Journal.
