Questions for Discussion: Hubble Telescope: Looking Deep

Why were the astronomers looking for an area that appears starless and desolate from Earth?
What did the Hubble telescope reveal in the dark area?
When we see galaxies that are 12 billion light years away, how old is the light that we are viewing? What could seeing light from galaxies so far away tell us about the origins of the universe?
If there are one to one hundred billion stars in each galaxy, and there are so many galaxies even in this tiny view of the universe, what does this say about the chances of finding planets like our own? Or about finding life on those planets?
