Scientists excited to find ocean of one of Jupiter’s moons contains carbon

Discovery adds weight to view that Europa's ocean could be most promising place in solar system to look for alien life

The vast subterranean ocean of Europa, one of Jupiter's many moons, contains carbon, one of the crucial ingredients for life, scientists have discovered.

The observations, by the James Webb space telescope, indicate that carbon dioxide ice on the moon's surface originated from the salty ocean that lies beneath a 10-mile thick crust of ice. Although the findings do not answer the question of whether alien life is lurking in the cold, gloomy depths, they add weight to the view that Europa's ocean could be the most promising place in the solar system to go looking for it.
