Thanks to @AstroKatie (astrokatie.com, twitter.com/astrokatie) for the collaboration!

Thus we can see not only stars and galaxies, but also the primordial stars & proto-galaxies, and even the remnants of the beginning of the universe itself: the CMB cosmic microwave background left over from the big bang.
