Mystery of Dwarf Planet Ceres’ white spots deepens

Ceres orbits the sun between Mars and Jupiter, and may have water gushing from its surface
Latest images to reveal the mystery patch were taken by Dawn at a distance of 29,000 miles (46,000 km)
Scientists suggest these strange spots may be frozen pools of ice at the bottom of a crater that reflect light 
Dawn is currently travelling to meet Ceres in March where it will attempt to understand its geological history
