Updating Our Address in the Galaxy

I like to know my address.  GPS now provides me with one accurate location metric.  Now Nature reports on another measure: " ... Earth's new address: 'Solar System, Milky Way, Laniakea' ... Analysis of galaxies shows local supercluster to be 100 times larger than previously thought. ... " . Add that to your drivers license.  A nice (Big) data visualization video is included.  Which visualizations describe the results well. .  The clustering methods used made me think of applications to other fields.
