NASA’s James Webb Space Telescope (JWST) has revealed homemade carbon dioxide on Jupiter’s icy moon Europa, raising the possibility that the frigid waterworld could host life.
The new detection by JWST is intriguing because the carbon dioxide does not seem to have been carried by a meteorite or asteroid, and it appears in a geologically young region of the moon called Tara Regio, suggesting the gas may have formed within the moon itself.
Co2 can be explained by natural (nonliving) phenomena. Its not something that can be used to deduce life on its own, so hopefully further analysis is encouraged!
