Discovery of Gases on Pluto's Largest Moon, Charon, Sheds Light on Outer Solar System Origins

Scientists have identified carbon dioxide and hydrogen peroxide on Pluto's moon Charon, offering insights into the evolution of icy bodies in the outer Solar System. Led by the Southwest Research Institute, the study utilized NASA's James Webb Telescope. Findings suggest the gases result from surface interactions and cratering events.

In a groundbreaking discovery, scientists have identified the presence of carbon dioxide and hydrogen peroxide on Charon, Pluto's largest moon. This finding could provide new insights into the origins and evolution of icy celestial bodies in the outer reaches of our Solar System.

Formerly the ninth planet, Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union. This reclassification occurred because Pluto had not cleared its orbit of debris, a key criterion for planetary status.

The research team, led by experts from the Southwest Research Institute, utilized the extended wavelength capabilities of NASA's James Webb Telescope to detect these compounds. Published in the journal Nature Communications, the study reveals that carbon dioxide likely originates from Charon's interior, exposed by cratering events, while hydrogen peroxide formation is attributed to UV light and cosmic rays affecting the ice-rich surface.
