Scientists at Brown University in Rhode Island believe tectonic movement could be taking place on Jupiter 's moon , Europa . Computer models suggest that differing salt levels , rather than temperature fluctuations , are behind the movement , prompting astrobiologists to question whether the – planetary plates moving beneath each other – could be capable of providing essential nutrients to any potential living organisms in the waters below the plates .
Scientists at Brown University in Rhode Island believe tectonic activity could be taking place on Jupiter's moon, Europa. Computer models suggest that differing salt levels, rather than temperature fluctuations, are behind the movement, prompting astrobiologists to question whether subduction – planetary plates moving beneath each other – could be capable of supplying essential nutrients to any potential living organisms in the waters below the plates.
