Saturn's 'Death Star' Moon May Hide Subsurface Ocean

Posted by samzenpus on from the that's-no-ocean dept.

astroengine writes With its heavily cratered, geologically dead surface, Saturn's moon Mimas was considered to be scientifically boring. But appearances can be deceiving. Using data from NASA's Cassini spacecraft, new research shows something strange inside Mimas that is causing the moon to sway as it orbits around the ringed gas giant. Computer models point to two possibilities. First is that Mimas, which is about 250 miles in diameter, has an oblong or football-shaped core, a clue that the moon may have formed inside Saturn's ice rings. The second option is that Mimas has a global ocean located 16 miles to 19 miles beneath its icy crust.

  2. The quesiton that interests me by i+kan+reed · · Score: 3, Interesting

    can it have life? We know life on earth adapted to survive on sulfur vents, which means sunlight based energy isn't necessary for life to continue.

    But what about abiogenesis? Miller-Urey showed us that lightning was a very important component in amino acids first appearing. Is there a tidal or geothermal way to cause the same thing?

    I'm pretty interested in the possibility of liquid water alone being enough.

      If it has liquid water, it has heat. Therefore there could be life.

  3. What? by KeensMustard · · Score: 2, Insightful
    Saturn's moon Mimas was considered to be scientifically boring. Is there really such a thing as a scale of scientific boredom? What is the unit of measure?

    I'd understand if TS said: considered a lower priority compared to the other bizarre and wonderful things in orbit around Saturn. That's believable given the level of freaky associated with some of the other satellites. But nothing about Mimas says 'boring'. As for scientifically boring I don't think that is a thing.

    1. Re:What? by Wycliffe · · Score: 1

      I think "rock" is synonymous with boring. We've pretty much concluded that the moon is boring which
      is why we've decided to explore elsewhere. The opposite of "boring" is of course "exciting". What
      makes something scientifically exciting is that it either is something we can't explain or helps confirm
      something we already think we know. What makes something boring is if there is nothing new to
      discover there. My backyard is scientifically boring. You're unlikely to discover something novel in
      it. It's possible to find a new mouse that is unknown but it's unlikely. The interesting non-boring
      stuff in our solar system are places that might harbor life or are most likely to help further explain
      physical processes like the creation of planets or the solar system.

      I daresay that geologists will disagree with you. So clearly, "boring" is not a scientific measure, it lacks objectivity.

      Also regardless of that Mimas could hardly be considered a 'rock'. It's made of rock (well, mostly), but look at the thing: http://static.ddmcdn.com/gif/s...
