New galaxy map relocates Milky Way To giant supercluster called Laniakea

Until now, the Milky Way was believed to be one galaxy in the 2,000 that make up what's known as the Virgo "supercluster." But as the new map shows, the Milky Way's 100 billion stars are actually part of something 100 times bigger: a supercluster of galaxies astronomers have christened Laniakea, meaning "immense heavens" in the Hawaiian language.

Laniakea spans some 520 million light-years across. As you might imagine, all those stars contain a lot of mass. In fact, astronomers say the supercluster is as massive as 100 million billion suns.
