Zoom sur la galaxy d'Andromede


Recommended Posts

La NASA vient de publier l'image la plus nette jamais effectuee de la galaxy d'Andromede. Un zoom sur une region qui s'etend sur une soixantaine d'annees lumieres et qui comprendrait plus de 100 millions d'etoiles (Andromede qui se situe a 2,5 millions AL de notre galaxye contiendrait milles milliards d'etoiles!). La mosaique qui ferait 1,5 milliards de pixels a requis 7398 expositions.
