An international team of astronomers has reported the discovery of a structure thought to be a “protocluster” of galaxies on its way to developing into a galaxy supercluster. Located 11 billion light-years from Earth, the observations show the protocluster as it appeared when the universe was 3 billion years old, during an epoch when stars were produced at higher rates in certain regions of the cosmos.
