Summary
Interstellar comet 3I/ATLAS JWST spectroscopy reveals water ice in tiny, dust-mixed submicron grains spectrally matching Kuiper Belt trans-Neptunian objects rather than solar system comets, suggesting the physical recipe for icy planetary building blocks may be universal across protoplanetary disks from different stars.
