Most elements heavier than iron are formed from exploding stars.
Why? Because it shouldn't be visible, not like that. That image should be a fog or completely black, nothing in between. To see that amount of detail, that amount of fine structure, those beautiful delicate rotating pinwheels, to see galaxies billions of light years away across almost an entire universe is absurd. It is more mathematically improbable than hitting the Power Ball Jackpot lottery five times in a row. That mind-blowing image is impossible without a super-finely tuned matter density gradient and alpha opacity function that is absolutely perfect.
The UDF is one of the many wildly improbable aspects of the physical Universe. It is unique in that it does not fall prey to a rebuttal based on the Anthropic Principle. (I believe that AP is the last, desperate, refuge of the cornered atheist.)

God designed the universe very carefully because I think that He wants us to marvel at the sheer majesty of His creation and see what He hath wrought. He wants us to see it. And in doing so we cannot help but be forever humbled by it.
The heavens declare the glory of God; the skies proclaim the work of His hands. (Ps 19:1)
