Image: Map of galaxies within the nearby universe. Laniakea is the part circled. The arrowed point marked by the Russian “Вы здесь” (“you are here”) is the Milky Way. “The present day dark matter distribution in a slice cut through a simulation of a flat universe with cosmological constant. The slice has a side length of 520 million light years, and a thickness of 100 million light years. It contains the so-called ‘supergalactic plane’. The major nearby clusters, like Coma, Virgo, Perseus, are labelled,” by Klaus Dolag, 19 January 2010, from Wikimedia Commons, CC BY-SA 2.5 Generic
