There may be a new way to improve weather forecasts. Scientists have found that the key to a better prediction may actually lie within examining the soil.
NASA's Dawn spacecraft has returned the sharpest images to date of the dwarf planet Ceres. Taken just 147,000 miles from the tiny planet on Jan. 25, the images represent a new milestone for the spacecraft as it continues its journey toward Ceres.
