The latest pictures were taken on Feb. 4 at a distance of about 90,000 miles from Ceres. The resolution is now 8.5 miles per pixel, and will obviously continue to improve as the spacecraft approaches the planet's orbit.
The white dot that comes into view as Ceres spins is something scientists are particularly interested in getting a look at. It's becoming more and more clear, and is definitely reflecting more light than the terrain surrounding it -- but for now, NASA researchers have no idea what it is. Good thing we're about to get even closer!
