Ceres' Mystery Bright Dots May Have Volcanic Origin 28

Posted by samzenpus from the stay-out-of-the-lava dept.
astroengine writes As NASA's Dawn mission slowly spirals in on its dwarf planet target, Ceres' alien landscape is becoming sharper by the day. And, at a distance of only 29,000 miles (46,000 kilometers), the robotic spacecraft has revealed multiple bright patches on the surface, but one of the brightest spots has revealed a dimmer bright patch right next door. "Ceres' bright spot can now be seen to have a companion of lesser brightness, but apparently in the same basin," said Chris Russell, of the University of California, Los Angeles (UCLA) and principal investigator for the Dawn mission. "This may be pointing to a volcano-like origin of the spots, but we will have to wait for better resolution before we can make such geologic interpretations."

    Shouldn't we wait until the probe actually arrives and gets details before speculating?

    There are bright spots on Ganymede (Jupiter moon) that are probably from meteors smashing into its icy surface.

    Even our moon has Tycho crater which is surrounded with bright dust due to the recency of the impact. (Radiation tends to darken soil and rocks over time.) Volcano claims are premature.

      There is no reason we should not be speculating now. Actually, we should be. This is a great time to be speculating about possible ways these areas could have formed, and what types of evidence for or against we should look for as the probe gets closer to support or dismiss our speculations. It lets us focus our efforts on what will give us the most bang for the buck once we get into orbit.

        I have no problem with private speculation, it's just premature to publish it when soon we'll have much better info.

  • Perhaps it is the correct time to remind people that in the plasma laboratory, current-carrying filaments tend to exhibit both long-range attraction and short-range repulsion. Setting the scientific framework's needs aside for a moment, that would seem to point more logically to an electrical inference. Note that we see a similar dipolar structure at the poles of Venus as well.

    The key test will be to observe whether or not they rotate around one another.

    If they do, then it's time for Slashdot to en

  • When I was younger, I remember reading a sci-fi novel about aliens in our solar system who were overseeing mankind's growth.

    The aliens chose their base on Ceres because the asteroid field offered nigh-unlimited resources outside the confines of a gravity well, because Ceres had water for living and powering fusion engines, and because it was far enough away from earth to stay out of sight.
