This kind of stuff is really awe-inspiring. I have a couple of questions for anyone who is knowledgeable on the subject:

1. Looking at the light from the tiny red-shifted galaxies that are ~13 billion years old... would the Milky Way appear the same to an observer ~13 billion ly from us?

2. What is the cause of the star pointed artifacts (specifically, having 6 major "points") for particularly bright objects? If you zoom in closely on any one of the points, you can almost make out a hex grid, as if the shape of the telescope's mirrors is the cause. Is that correct?
