From a vantage point about 915 miles above the surface of Ceres, a dwarf planet in the main asteroid belt, NASA's Dawn spacecraft captured some of the best views yet of an odd crater that has mysterious bright white spots on its floor.
The pictures are about three times better resolution than Dawn's previous images, but scientists are still mulling over what the spots could be.

The new images also revealed that in some places the crater's rim is nearly vertical, rising about 1 mile from the floor.
Over the next two months, Dawn is expected to map Ceres six times, with each orbit at a slightly different angle so scientists can piece together stereo and three-dimensional views.
Scientists suspect Ceres, which is about 590 miles in diameter, may have had an underground ocean at some point and could still have liquid water beneath its icy surface.
We STILL Don't Know What Those Bright Blobs on Ceres Are
Before arriving at Ceres in March, Dawn spent 14 months exploring Vesta, the second largest object in the asteroid belt, located between Mars and Jupiter.
