Andromeda galaxy vs Milky Way galaxy

Communications of the Byurakan Astrophysical Observatory
Some physical features of the Andromeda galaxy are compared with their counterparts in the Milky Way to demonstrate that the Andromeda galaxy has traversed a longer evolutionary path. One of the evolutionary dependents in galaxies is the metallicity factor. The metallicity radial gradient in galaxies can also be used for this purpose.
