New images from Dawn mission to Ceres

Dawn spacecraft has now moved to within about 900 miles (1,500 km) from the dwarf planet Ceres. See some early images from its new, closer orbit.

(The lower right edge of Pluto in this view currently lacks high-resolution color coverage.) The images, taken when the spacecraft was 280,000 miles (450,000 km) away, show features as small as 1.4 miles (2.2 km). Image via NASA/JHUAPL/SwRI.
