MACS 1149-JD is the now the oldest, most distant Galaxy discovered to date. It began forming during the "dark ages" just 300Million years after the BB and was viewed here on Earth as it was when the Universe was 500Million years old.

My question is, are these estimated ages still consistent with the age of the Universe, the time required for stars to form, and for the stars to form into a galaxy, albeit 1% the size of our own today?
It will be very interesting to see whether the JW telescope sheds any new light on this as well as any even older galaxies.
