New James Webb Space Telescope observations present a fresh challenge to long-held ideas about the chemistry of planet-forming disks, revealing a surprisingly high concentration of carbon dioxide in regions that may eventually give rise to Earth-like bodies. Human scientific instruments trained on such planet-forming regions pick this up as water vapor signatures emanating from the inner zones. What defies expectations in the new research is the presence of a strong carbon dioxide signature detected by the James Webb Space Telescope, originating from the center of a planet-forming disk rather than the center of the star. “This challenges current models of disk chemistry and evolution since the high carbon dioxide levels relative to water cannot be easily explained by standard disk evolution processes,” Frediani explains.
