This is an interesting question. Many strides have been taken in space exploration through Hubble and the Spitzer infrared space telescopes. Each year brings an expansion to the distance to which scientists can see thanks to these space telescopes that orbit in space rather than view space from Earth. It is possible that your source of information got his or her data mixed together and told two or more advancements as one. I suspect the first is this. Hubble has in recent years detected "black envelopes" around (1) young protostars in early formation phases and (2) black holes inside black envelopes of swirling gas.
I suspect the second may be this. Astronomers and cosmologists now think that "dark flow" indicates a proof of the multiverse theory. Scientists now suggest another bubble multiverse is at the edge of our universe and is exerting a strange pull. This pull is causing the cosmic microwave background (CMB) to ripple and is causing the galaxies all over the universe to flow in the same direction toward one specific locale--this is opposed to a uniform unrippled expansion that spreads outward in all directions from one central locale.
When these two cosmological accounts (i.e., black envelopes and multiverse dark flow) combine casually, you may get something that sounds rather like "they reach a black envelop which no machine from earth can ever penetrate through to the other side, and they say on that other side that is where Heavenly Father God is." For a person of religious faith, a reasonable counter-argument to the multiverse theory might be that the '"structure" at the edge of our universe is Heaven--beyond the bounds of space and time--and that it is exerting a pulling spiritual influence upon our universe.
As to distance, this is an unanswerable question because we do not know if the farthest thing Hubble has detected is the last farthest thing: we don't know yet where the edge of our universe is. Further, God is super-natural thus beyond the confines of nature, i.e., space and time. As of May 2011, an explosion of a gamma-ray burst was labeled the probable farthest thing seen in the universe; it is estimated to be 13.14 billion miles away. Do remember that God, Yahweh, the Lord God Almighty, Allah, is by definition outside space and time and therefore at no set distance, as distance is a function of space and time.
