Chiron is a mysterious centaur. The JWST telescope found that it’s built like a layered cake: methane seeps from within, carbon dioxide evaporates from the crust, and carbon monoxide is hidden deep inside. This arrangement upends traditional models of icy wanderers.
🎯 On most active asteroids and comets, carbon monoxide is the primary gas. Chiron defies the norm: here, methane dominates, while carbon monoxide stays locked inside.
