The James Webb Space Telescope has successfully detected both carbon dioxide and hydrogen peroxide on the moon, adding to what we know of its unusual composition. Charon is an important object for planetary scientists.

Researchers said the carbon dioxide observed by Webb was probably buried underneath the surface and exposed by impacts on Charon. Observations by the James Webb Space Telescope are giving scientists a fuller understanding about the composition and evolution of Pluto’s moon Charon,

Researchers studying Pluto’s small moon, Charon, found something remarkable: carbon dioxide and hydrogen peroxide. This is the first time these chemicals have been discovered on the frozen surface of that particular moon.
