Gr\u00e2ce \u00e0 ces cam\u00e9ras, l\u2019ESA a pour objectif de d\u00e9terminer la forme et la taille des galaxies, ce qui devrait permettre d\u2019\u00e9tudier l\u2019\u00e9volution de l\u2019univers au cours des dix derniers milliards d\u2019ann\u00e9es.<\/p>\n\n\n\n<p>\u201cBien que ces premi\u00e8res images ne soient pas encore utilisables \u00e0 des fins scientifiques, je suis heureux de constater que le t\u00e9lescope et les deux instruments fonctionnent parfaitement dans l\u2019espace\u201d, a d\u00e9clar\u00e9 Knud Jahnke, de l\u2019Institut Max Planck d\u2019astronomie de Heidelberg.
