12 billion miles in 40 years of travel. The machines built by humans that will continue to roam the universe long after the people and planet that made it will cease to exist.

The mysterious "bright spots" on Ceres.  Highly unusual due to the limited and concentrated spots.  Could be an impact site of a small meteor that cleared underlying ice, but other impact sites on the dart planet do not show the same effect.  Could be a cryovolcano, but the pattern does not match a geyser effect.  We should be a better answer over the next few weeks as the images get better and DAWN goes into orbit around Ceres.
