NASA's Webb Telescope Detects Carbon Dioxide On Surface Of Pluto's Largest Moon Charon

 

Scientists utilizing the James Webb Space Telescope have made a groundbreaking discovery on Charon, Pluto's largest moon. For the first time, researchers have detected carbon dioxide on Charon's frozen surface, according to a study published in Nature Communications. Led by the Southwest Research Institute, the team found traces of carbon dioxide and hydrogen peroxide on the moon, which is roughly half the size of Pluto. This breakthrough discovery builds upon previous findings of ice, ammonia, and organic compounds on Charon.

The study explains that hydrogen peroxide forms when ice is broken down by charged particles, releasing hydrogen and oxygen atoms that combine. This highly reactive compound is commonly used in bleaches and disinfectants. The presence of the chemical suggests Charon's icy surface is altered by ultra-violet light and solar wind from the distant Sun, according to the study. The discovery sheds new light on Charon's composition and chemical processes, offering valuable insights into the Pluto system's mysterious and icy landscape.

"The detection of carbon dioxide was a satisfying confirmation of our expectations. The detection of hydrogen peroxide on Charon was unexpected. I honestly did not anticipate finding evidence of it on the surface," said Silvia Protopapa, lead author of the study.
