Extremely distant galaxy cluster detected

Astronomers at Swinburne University of Technology have discovered a densely-concentrated galaxy cluster 10.5 billion light-years from the Milky Way, making it the most distant cluster yet found.

The cluster, which contains 30 galaxies, is being observed at a time when the Universe is only three billion years old. This means that the cluster is very young, and should develop over time into a much denser structure containing many more galaxies. The observation of such a young galactic cluster will help astronomers understand better how the formation of galaxies is influenced by their environment.
