Using data from the Near-Infrared Spectrograph (NIRSpec) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected carbon dioxide (CO2) and hydrogen peroxide (H2O2) on the frozen surface of Pluto’s moon Charon. Their findings provide new insights into the chemical processes and surface composition of Charon, which could help us understand the origin and evolution of icy bodies in the outer Solar System.
