Actually it's only the visible frontier we can see yet, since the light has yet "just" traveled 15 billion LY to us, which is called the Hubble Distance, but the space expansion has continued on, so the real expansion is estimated by the astronomer by approximately 46 billion LY, three times greater than now.
And no, there's no edge of the universe, since space hasn't expanded there yet, there's also no time. Nothing, Zero, Nada...
