What I like about this Hubble/Webb follow-up on

What I like about this Hubble/Webb follow-up on Trans-Neptunian Objects is that it’s not just “we found icy rocks far away.” Their surface chemistry still carries traces of where and how they formed billions of years ago, despite spending most of solar system history in deep freeze beyond Neptune. That makes the outer solar system feel less like a static junk drawer and more like an archive with surprisingly intact records.
