This is pretty cool: New Map Locates Milky Way in Neighborhood of 100,000 Galaxies.

A new map of the Milky Way’s cosmic neighborhood shows where our galaxy lives in relation to thousands of others nearby, with scientists giving the newly discovered “supercluster” of galaxies a name: Laniakea, which means “immeasurable heaven” in Hawaiian.

Throughout the universe, galaxies tend to clump together in massive structures that astronomers call superclusters. According to the new map, Earth’s galaxy lives near the edge of the Laniakea supercluster, which measures 500 million light-years in diameter and includes roughly 100,000 galaxies.

The region is just a small slice of the visible universe, which spans more than 90 billion light-years.

As someone who spends his share of time reading about astronomy, I’ve often wondered why most astronomical literature rarely identified the galactic supercluster that we live in, despite mentioning others like Coma or Perseus-Pisces.  I’ve occasionally…
