"Reassessing Europa's Oxygen Levels: Implications for Habitability"

NASA's Juno spacecraft has revealed surprising findings about the rate of oxygen production at Jupiter's moon Europa, estimating it to be around 26 pounds every second, substantially less than previous studies. This discovery has implications for the potential habitability of Europa, as some of the oxygen produced could work its way into the moon's subsurface ocean as a possible source of metabolic energy. The findings were derived from data collected by Juno's Jovian Auroral Distributions Experiment (JADE) instrument during a close flyby of Europa. The upcoming Europa Clipper mission in 2030 will further investigate Europa's potential for life.
