Planetary systems, as they form

We can look at them. Each one of those blown up squares is what's called a proplyd, which is a disk of dense gasses circling a star. Many of them will eventually coalesce into planetary systems, like our own or any of the hundreds we know of, and countless billions more that surely exist. That we can just look at this happening is beyond all words.

Also beyond all words is the fact that each of those tiny little squares in the larger image is alone larger than the human mind can comprehend.
