UVES Investigates the Environment of a Very Remote Galaxy11 March, 2002. Observations with ESO's Very Large Telescope (VLT) have enabled an international group of astronomers to study in unprecedented detail the surroundings of a very remote galaxy, almost 12 billion light-years distant. The extremely detailed UVES spectrum of MS 1512-cB58 displays numerous signatures (absorption lines) of intergalactic gas clouds along the line-of-sight . An excess of material near MS 1512-cB58 was found, possible evidence of a young supercluster of galaxies, already at this very early epoch.
