The location of LBG-2377 (circled in red)

LBG-2377 is the most distant galaxy merger discovered, as of 2008, at a distance of 11.4 billion light years.[2] This galaxy merger is so distant that the universe was in its infancy when its light was emitted. It is expected that this galaxy proto-cluster will merge to form a brightest cluster galaxy, and become the core of a larger galaxy cluster.
