A computer model showing the Laniakea galaxy supercluster and our place within it. The red dot in the image represents not Earth or the Solar System, but the Milky Way.
Scientists have long sought to determine exactly where our galaxy is located in the Universe. In 2014, a research team compiled data on nearly 100,000 galaxies and mapped their locations and movements through space. For the first time, we saw that the Milky Way is part of a much larger system of galaxies—a supercluster that scientists named Laniakea.
This supercluster has an approximate diameter of 520 million light-years, and the Milky Way is situated far from its center, practically at its very edge.
On the opposite side of Laniakea from the Milky Way lies a gravitational anomaly known as the Great Attractor, toward which the majority of the supercluster's galaxies (including our own) are migrating.
