This image, snapped by the Dawn spacecraft on January 25, 2015, is the sharpest yet of Ceres, the largest asteroid. Taken from a range of 147,000 miles (237,000 km), the image shows more detail than even the best taken by Hubble Space Telescope. Dawn will draw closer to Ceres over the next few weeks and enter orbit around the little dwarf planet on March 6. [NASA/JPL/UCLA/MPS/DLR/IDA]
