NASA's Webb Space Telescope detects carbon dioxide and hydrogen peroxide on Pluto's largest moon, Charon.

NASA's Webb Space Telescope has detected carbon dioxide and hydrogen peroxide on Charon, Pluto's largest moon, marking the first identification of these chemicals on its surface. Previously known to be covered in water ice, Charon's new findings could enhance understanding of its formation and similar distant moons. Scientists suggest hydrogen peroxide may arise from radiation effects, while carbon dioxide could be linked to impact events.
