That's a fun question! There isn't a standardized "address" system for galaxies, so we can't just say what comes after "Milky Way."

However, we can think about how we might organize galaxies if we *did* have a system:

* Local Group: Our Milky Way is part of a group of about 50 galaxies called the Local Group. So, the next level of organization would be to specify which galaxy within the Local Group we're talking about.

* Virgo Supercluster: The Local Group is a part of the Virgo Supercluster, a massive collection of galaxies. We could then specify which part of the Virgo Supercluster we're interested in.

* Observable Universe: The Virgo Supercluster, and all the other galaxy clusters and superclusters we can observe, are within the observable universe.

So, to answer your question more fully:

* After Milky Way: You'd need to specify the Local Group and then the part of the Virgo Supercluster the Milky Way is in.

* Beyond that: We'd need to specify how far out from the Virgo Supercluster and within the observable universe we're talking about.
