ANOTHER LINE ADDED TO OUR COSMIC ADDRESS

Astronomers have just added another line to our comic address in the form of a newly identified supercluster Laniakea. Most galaxies are arranged in groups and clusters, with groups containing dozens of galaxies and clusters comprised of several thousand. 3-10 clusters form even larger structures called superclusters that can span hundreds of millions of light-years across. Our newly-defined supercluster spans 500 million light-years and contains the mass of 100 quadrillion suns in 100,000 galaxies. Laniakea is the Hawaiian term for “Immense Heaven”, but I would have added a bit more pizzaz like the term for “Immense Bad-Asses Live Here”.
