An international team of astronomers has announced the discovery of an enormous and surprising structure, formed fairly early in the lifetime of the universe. This structure is a "supercluster" of galaxies, created when many galaxies are bound together by the force of gravity. Conceptually, you can imagine it as looking similar to a swarm of bees, albeit on a cosmic scale, and each bee being replaced with an entire galaxy full of hundreds of billions of stars.
