:::::::::::There most certainly are stars 39 billion light years away, or close to it. That's the cosmological principle in action. But, as Aschlafly pointed out, they're not going to be observable because light from those stars has not had time to get to us, and if we attempted to look back that far, we will eventually hit the "wall," so to speak, as a result of the opacity of the early universe.

:::::::::::::Nobody's observed them. The most distant object anyone has ever observed is the galaxy UDFj-39546284, which - if it still exists, which is unlikely - is 31.7 billion light years away and is now way outside the observable universe. The light from it has travelled 13.2 billion light years to get to us. --[[User:GeorgeLi|GeorgeLi]] 21:22, 30 January 2012 (EST)
