And just what advantage and how could this top what we get from the hubble space telescope?

It's much larger and thus has far more light-gathering capability than Hubble.

And adaptive optics techniques that constantly and automatically compensate for atmospheric distortion mow greatly reduce the advantage of optical space telescopes over ground-based ones.

If they could put this telescope on the Moon just think about how far it could peer into the universe.
