Given that the Hubble Ultra Deep Field measures 3 arc minutes on a side how many HUDFs would it take to cover the entire sky?
Never mind... Found the answer on the STScI web site. But for those who are interested: "The whole sky contains 12.7 million times more area than the Ultra Deep Field." So lets see, if it would take 13 million HUDF's to cover the sky and each field contains ~10,000 galaxies and each galaxy contains, oh say, a couple of hundred billion stars, I guess that means there are a lot of stars out there.
