A NASA spacecraft that launched in 2007, is closing in on the dwarf planet Ceres in the solar system's asteroid belt has captured tantalizing new views of the huge space rock, revealing hints of craters and other structures on the surface of this mysterious body. NASA's Dawn spacecraft snapped the new images of Ceres, which is the largest object in the asteroid belt between the orbits of Mars and Jupiter, on Jan. 13. Scientists unveiled the images on Monday (Jan. 19). Dawn is rapidly approaching Ceres and is due to arrive in orbit around the dwarf planet on March 6. The images are still blurry, and are primarily for navigation purposes for Dawn, but they show hints of craters on Ceres' surface, including a mysterious white spot near the upper left, which may be light reflecting off of a crater. By early to mid March they will have a clear shot of what Ceres actually looks like.
