(ANSA) – VICENZA, 31 MAG – Quanti anni hanno le stelle della Via Lattea? Usando un nuovo metodo nell’assegnazione di un’eta’ alle popolazioni di stelle, un gruppo di studiosi coordinato da Jason Kalirai dello Space Telescope Science Institute di Baltimora ha stimato l’eta’ della parte piu’ esterna della Via Lattea a circa 11,4 miliardi di anni. La ricerca e’ stata pubblicata su Nature. Le misurazioni consentiranno di ottenere informazioni utili sull’evoluzione dell’intera galassia di cui fa parte il sistema solare.
