Gases Detected on Pluto's Largest Moon

  • 03 Oct 2024

In October, 2024, Scientists discovered carbon dioxide and hydrogen peroxide on Charon, Pluto's largest moon, offering insights into the evolution of icy bodies in the outer Solar System.

Key Points

  • Charon’s Atmosphere Revealed: Researchers from the Southwest Research Institute, US, detected carbon dioxide and hydrogen peroxide on Charon for the first time. This discovery enhances our understanding of how icy celestial bodies form and evolve.
  • Origins of Carbon Dioxide and Hydrogen Peroxide: The study suggests carbon dioxide likely originates from Charon's interior, exposed through cratering events. Hydrogen peroxide forms when ice is bombarded by solar particles.
  • NASA’s James Webb Telescope: The extended wavelength capabilities of NASA’s James Webb Telescope enabled scientists to study Charon’s surface in more detail, helping them detect these gases for the first time.
  • Pluto’s Dwarf Planet Status: Pluto was demoted to a dwarf planet in 2006 due to its inability to clear its orbit of debris, according to a resolution by the International Astronomical Union.
  • Uninhabitable and Ice-rich Surface: Despite the presence of ice, Charon’s extremely cold environment makes the existence of life impossible.
