Chiron releases methane from its depths, carbon dioxide from the surface, and carbon monoxide is locked inside. This reshapes models of how icy bodies behave.

Spectrograph NIRSpec aboard the JWST telescope has discerned a complex mosaic of carbon dioxide and carbon monoxide bands on Ariel, Umbriel, Titania, and Oberon. Comparison with laboratory ices at cryogenic temperatures revealed signatures of crystalline CO₂, clathrates, and carbonates. The observed
