Helium Summary: Recent research using the James Webb Space Telescope (JWST) has revealed the presence of carbon dioxide and hydrogen peroxide on Pluto's moon Charon.

This significant discovery adds depth to our understanding of Charon's geological history and composition, previously dominated by the knowledge of water ice and organic materials.

The research, led by Silvia Protopapa from the Southwest Research Institute, utilized advanced observational techniques to discern that the carbon dioxide likely originates from the moon's subsurface, exposed by impact cratering.

Furthermore, the hydrogen peroxide presence indicates alterations from solar and cosmic radiation processes, reflecting on Charon's environmental conditions over time.

These findings inform scientists about the formation and evolution of Charon and similar trans-Neptunian objects, marking an advancement in planetary science and nomenclature associated with icy celestial bodies .
