IIRC it is radiation bouncing off its clumps of hydrogen from nearby stars.

Ah, so radiation is being emitted and blocked in a way that coincides to the way we interpret 3d objects, is that right? Because if it would be uniform, the bright orange colors would be uniformly distributed?

It's not coincidental, this is how our vision works.

No, I was thinking in terms that the pillars are glowing and illuminating themselves, which would be really coincidence to have this luminescence only on areas that would look like a shadow or not.

It turns out that for my original question, there is actually something illuminating it from the top-right. As massive as the pillars are, they are part of a yet bigger structure [0] and the brightness generated is allowing us to see it with better depth. It's really incomprehensible to grasp how large things can get.

to preserve the meaning he intended with the meaning you are trying to refute, try instead the word "coincident"

It's not coincidental that the phenomena are coincident to how our vision words, the geometry of the science coincides
