Cosmology

Meet the Laniakea supercluster

Nature volume 513, pages 41–42 (2014)Cite this article

Subjects

An analysis of a three-dimensional map of galaxies and their velocities reveals the hitherto unknown edges of the large system of galaxies in which we live — dubbed the Laniakea supercluster. See Letter p.71

One of the greatest advances in cosmology has been the discovery of how matter and light are organized on scales larger than those of galaxies1,2. However, despite tremendous effort, astronomers have been unable to map in detail the large-scale cosmic structure in which the Milky Way resides. Now, on page 71 of this issue, Tully et al.3 report an analysis of data from a vast catalogue of galaxies that has allowed them to do just that.
