Hot off the ABC news site.

The test star was 2000 LY away, the galaxies obviously a bit further. The telescope seems to be functioning as planned, once it is up and running there could be some interesting data forthcoming. :eyepop:

If it can see back to " a couple of million years after the big bang" what will that be like?
Gallaxies within an arms length from each other?
Not much time to expand so????

Also seems too little time for galaxies to form, each new discovery and image seems to me to be counter intuitive. Assumptions on assumptions.

Probably just nucleus's of galaxies which grew as the universe
expanded.
Most galaxy bulges are comprised of old stars,so that
would make sense.
The big question is, which came first, Black holes with
the galaxy developing around them, or lots of merging
black holes making one big one at the centre caused by
the myriad of supermassive stars collapsing into black
holes?
How else would you get a Million/billion solar mass black hole
at the center of just about every galaxy in the Universe.
Thoughts?:question:

for interest, gives a pretty clear summary of the science goals.
