LBG-2377

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.

Observations were conducted with the Keck Telescope in Hawaii by Jeff Cooke, a McCue Postdoctoral Fellow in physics and astronomy at UCI.

While looking for single galaxies, Cooke found something that at first appeared like a bright, single object.

However, further analysis of wavelengths of the emitted light proved that they were three galaxies merging, and likely two smaller galaxies.
