Bright spots on Ceres came from salty water insideChristian Fernsby ▼ | August 11, 2020
One of the mysteries the images raised was what caused the bright spots on the surface of Ceres.
Sodium carbonate is a compound of sodium, carbon, and oxygen.
Researchers believe that the liquid likely came to the surface and evaporated, leaving behind a highly reflective salt crust.
One major mystery that remains is where exactly the liquid came from.
Dawn mission scientists have determined that the liquid came from a deep reservoir of brine, or salt enriched water.
The researchers believe that the reservoir is about 25 miles deep and hundreds of miles wide. ■
