Salty Ceres
Featured on April 11, 2016
Bright white patches in the center of Occator Crater on Ceres, the largest asteroid, may consist of magnesium sulfate, the mineral used in epsom salts, according to recent research. The Dawn spacecraft snapped these images of the bright spots earlier this year from an altitude of about 240 miles (385 km). [NASA/JPL/UCLA/MPS/DLR/IDA/PSI]
