Asteroid Ceres is a former ocean world that slowly formed into a giant, murky icy orb

A crater-rich dwarf planet named Ceres located in the main asteroid belt between the orbits of Mars and Jupiter was long thought to be composed of a materials mixture not dominated by water ice. Researchers at Purdue used data from NASA's Dawn mission to show that Ceres' crust could be over 90 percent ice.

The ground that was beneath this ice is also shifting and rising as these glaciers disappear. Geologists have discovered a link between recent ice mass loss, rapid rock uplift and a gap between tectonic plates that underlie Patagonia. from Phys.org - latest science and technology news stories https://ift.tt/j1h2ds5
