Abstract

M31, our nearest large galactic neighbour, offers an opportunity to study in superb detail the processes which drive the formation and evolution of spiral galaxies. Over the last decade, our view of this oft-considered quiescent system has been revolutionized as a result of wide-field photometric and spectroscopic surveys from the ground, as well as deep pencil beam studies with HST. These studies, which have probed the galaxy to unprecedented surface brightness levels and established the outer stellar boundary to be at least similar to 150 kpc, reveal that M31 has had a much more violent history than previously thought, having devoured at least one moderate-sized luminous satellite in the recent past. I review here some key results, focusing on the particular role that HST has played.
