Ceres is a dwarf planet and the largest known object in the asteroid belt between Mars and Jupiter. And now we know it may be an ocean world with intriguing geologic activity taking place on and just below its surface, according to new research.
While this global ocean beneath the planet's surface likely froze over time, remnants of it may still be present beneath a large impact crater on Ceres. The presence of salts may have preserved the liquid as a brine, despite cold temperatures.The suite of seven studies published Monday in the journals Nature Astronomy, Nature Geoscience and Nature Communications. Between 2011 and 2018,
's Jet Propulsion Laboratory in California, in a statement. Dwarf planet Ceres reveals pyramid-shaped mystery"The impact heat subsided after a few million years; however, the impact also created large fractures that could reach the deep, long-lived reservoir, allowing brine to continue percolating to the surface."There are also mounds and hills visible in the crater likely created when flows of water froze in place, suggesting geologic activity on Ceres.
