What the universe looked like

Wednesday 09 December 2009 by Ian Pettman

Actually the title is somewhat incorrect. It is what the universe looks like now, except that some of the light has been traveling for 13 Billion years to get to the Hubble deep space telescope.  

These are the latest pictures of the universe's early day that have been released. The farthest galaxies are the red ones  (due to red shift) and we see them as they were only 600 million years after the big bang. With the current estimate of the age of the universe being 13.7 Billion years, this means that we have gone (are viewing objects) back 96% of the way to the beginning of the universe.
