NASA takes close-ups of Ceres’s strange white spots. Still can't explain them.

Back in February, footage from NASA's Dawn spacecraft revealed something strange on the dwarf planet Ceres - two white patches reflecting brightly in the middle of a huge, dark crater.
The first assumption was that they were big patches of ice, but the wavelengths of light they're reflecting didn't quite match up. Dawn has since entered the orbit of Ceres and taken a whole lot more incredibly detailed images of the planet's fascinating surface. But each set is just triggering more questions than it can answer.
