NASA's Dawn Gets Closest-Ever View of Dwarf Planet Ceres

What the mysterious dwarf planet looks like up close.

It will be the first time the spacecraft has visited a dwarf planet. NASA launched a mission to explore the 590-mile diameter cosmic mass in 2007.

The mission is expected to continue for 16 months as researchers analyze data about Ceres, which is thought to be icy and possibly contain an ocean. Researchers said images taken from the closer view show what appear to be craters -- something they're eager to get a closer look at as Dawn edges toward its destination.
