Researchers have now determined that the broad areas are deposits made mostly of sodium carbonate.

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.
