Zoom into ACS Image of M31 Halo

A Zoom into the constellation Andromeda reveals the magnificent galaxy M31. Zoom continues to Hubble's Advanced Camera for Surveys image of a small portion of the M31 halo of stars. This spherical halo of stars surrounding the neighboring Andromeda galaxy has revealed surprisingly younger stars ranging in age of 6 to 13 billion years compared to the 11 to 13 billion year age of the stars in the Milky Way's halo.
