(13,560 posts)24. Before the distant galaxies recede, never to be seen again,...
the amount of stars we see will increase until we reach the future visibility limit.
This article talks a bit about that.

It also lays out the stunning fact that everything we can see, as far as we can see, is a tiny, tiny fraction of the entire universe.
The future visibility limit will take us to distances that are presently 61 billion light-years away, but no farther. It will reveal slightly more than twice the volume of the Universe we can observe today. The unobservable Universe, on the other hand, must be at least 23 trillion light years in diameter, and contain a volume of space that's over 15 million times as large as the volume we can observe.

I do see he's at Penn State, which is possibly the foremost school for exoplanet research.

My Son The Astronomer does know him, although not well, as MSTA is not at Wright's level.
