Astronomers Find Evidence of Cosmic Climate Change

Published on 02/11/2010 

A team of astronomers has found evidence that the Universe may have gone through a warming trend early in its history. They measured the temperature of the gas that lies in between galaxies, and found a clear indication that it had increased steadily over the period from when the Universe was one tenth to one quarter of its current age. This cosmic climate change is most likely caused by the huge amount of energy output by young, active galaxies during this epoch.
