Paired Galaxies

Today's Astronomy Picture of the Day shows two members of our Local Group, Messier 31 (the Andromeda Galaxy) and Messier 33 (the Triangulum Galaxy). I've only been lucky enough to spot Triangulum a few times (the Andromeda used to be an easy backyard naked eye target hereabouts, but no more).
