They conclude that the carbon dioxide in the moon Europe occurred in the inner ocean

If there is alien life in the Solar System, one of the candidates is the Jupiter Europe, which, according to observations made so far, has a liquid ocean under its skin. In addition, it should have other essential elements to create life, including carbon. And on the surface, it has frozen carbon dioxide. Now, based on data from the JWST telescope, they've come to the conclusion that this carbon dioxide is produced in the ocean.
They announced it in Science through two articles. Carbon dioxide has been mapped and found to be particularly abundant in the Tara Regio area. This area is chaotic and young materials predominate. So they believe that the origin of carbon dioxide is the underlying ocean, whether it's in the form of carbon dioxide, carbonate or organic compound, and then transform it into carbon dioxide.
The other study analyzed four spectral characteristics of carbon dioxide ice. And there you've also seen that the tara is concentrated and has other mixed materials. Carbon isotopes have also been analyzed and their exit from the interior has been confirmed. What they do not know is whether its origin is biotic.In any case, it is significant to say that in Europe, besides liquid water, there is carbon.
