Piero Rosati in front of whiteboard, explains about the cosmological implications of looking this far out: ?When Hubble looks at the distant Universe it looks back in time. We can sketch this: This is Hubble and here we are 14 billion years after Big Bang. The first Hubble Deep Field could see out to here ? 12 billion years of cosmic history. The New Ultra Deep Field push this exploration beyond ? further back in time. For the first time we are able to see the stars and galaxies which were formed right at the end of the so-called Dark Ages.?
