Er, the 156 billion light years is what we can see.
That's being misreported in the article.
The radius of the observable universe, as defined in the article, is about 46.5 Gly, not 78 Gly.
Cornish et al. actually reported a minimum diameter (minimum translational distance) of the whole universe of 78 Gly.
There are some more glitches in those articles, obviously the press release was not really well formulated.
