In 2005, observations of this object's outer disk indicated it may be almost twice as large as previously thought. Myall II is a globular cluster in this object, and it may be starting to become a ring galaxy, although it is currently a(*) barred spiral. Observations of supernovae in this galaxy helped show for the first time that it and other galaxies are not nebulae, and this galaxy, whose satellites include M32 and M110, displays a prominent blue shift. For 10 points, identify this closest major galaxy to the Milky Way, named after the constellation it appears in.
