  • Those pesky lights on Ceres

    The latest theory being advanced after close inspection of images from much nearer is that the "lights" are actually whitish sulfate deposits which reflect sunlight.

    Who knows?

    I was just about to dig up the older thread on this, so ... something I found during the recent "down time";
    Has the mystery of the 'alien' marks on Ceres been solved? Bright spots on the dwarf planet's surface may be WATER ICE

    • Experts from the Max Planck Institute for Solar System Research in Germany think the 130 bright spots detected on Ceres, may be water ice
    • Used data from the Framing Camera on board the Dawn spacecraft
    • Showed Occator crater contains a central pit covered by bright material
    • Material shows evidence for water ice sublimation resulting in haze clouds

      Don't forget that Ceres is quite dark, about the same colour as bitumen. Any underlying substance that is lighter in colour will be more easily seen.

        I suspect the Death Star's camo will be stripped clean soon, probably in time for the US debut of Episode VII.

            And it would make sense that such a deposit would be laid bare in an impact crater, but if it's a pervasive deposit, why not in the bottoms of other, nearby craters?

              Maybe it reacts to UV light? Solar wind erosion? Be nice to have some samples to examine.

                  Here's an interesting "geological" (planetological?) anomaly,
                  The mysterious 'pyramid of Ceres' up close: Stunning new images reveal three mile high mountain has a strange 'glowing' side

                  • Astronomers say they are still baffled by how the giant mountain formed on the surface
                  • 'Pyramid' is in fact a dome with smooth, steep walls - one of which appears to glow

                  It is one of the many mysteries of Ceres - a gigantic pyramid in among the vast craters and 'alien spots'.
                  Now, Nasa has revealed stunning new close up images of the three mile high mountain Ahuna Mons.
                  They reveal the 'pyramid' is in fact a dome with smooth, steep walls - one of which appears to glow.

                    The "glowing" appears consistant with the shadows in the larger craters.

                      Yes, but what is this "reflective" material that shines so bright, and is nearly three miles high?

                          This image is hard to explain. The surfaces of the Crater walls and Hill are VERY SMOOTH. This is unlike the surface of the bottom of the crater and top of the Hill.


                          Normal "weathering" processes don't explain what is going on here.

                            Great image! I would say we are seeing the reflected light off those surfaces - the "albedo", but that certainly does not explain the surfaces themselves.

                              Ceres is not that close to the Sun so the light level cannot be all that high anyway which would suggest a very reflective surface (or the gain on the probe is turned up way too high!)
