M31 is the brightest & nearest of all spiral galaxies & with a diameter of 180,000 light years is one of the largest galaxies known. Two satellite galaxies of M31 are visible. They are NGC 205 at upper right & the brighter stellar-like object M32 (NGC 221) at bottom centre. Many dark lanes are present in M31. They are caused by clouds of dust which absorb & scatter the light emitted here.
