(Phys.org)-A team of researchers from several institutions in France and Mexico has developed computer models that simulate conditions on Saturn`s largest moon Titan showing that some of the islands on the planet`s surface may be made of bubble streams. In their paper published in the journal Nature Astronomy, the team describes how they built their model and explain how bubble streams could form on the surface of Titan.
