Summary

Story summary

Researchers from The University of Chicago and the Jet Propulsion Laboratory report Jupiter's oxygen exceeds solar levels by 1 to 1.5 times, based on carbon monoxide.
Models show gas mixing is slower than previously thought, supporting higher oxygen.
Jupiter's carbon-to-oxygen ratio is nearly three times solar, suggesting formation in a carbon-rich environment.
The Planetary Science Journal published the findings, which advance understanding of gas giants.
