Astronomers currently believe that when the universe was a billion years old or so (as opposed to the 14 billion years old it is now), it was full of small galaxies which were merging together to form bigger ones - and it was by this process that all of the big galaxies we see today were formed. Wouldn't it be great if we could somehow observe the same thing nearby, so we can study it better? Well, Hubble and GALEX may have discovered such an example. Go here for the details. Enjoy!
