Ariel, Uranus' moon, shows signs of a massive subsurface ocean, potentially 100 miles deep, revealing geological mysteries ...

Growing evidence suggests that a subsurface ocean lurks beneath the icy surface of Uranus' moon Ariel, but new research, published in Icarus, characterizes the possible evolution of this ocean, and ...

Carbon from deep grooves on Uranus’ moon Ariel? Ariel has carbon dioxide ice and other carbon deposits on its surface. How did they get there? The study last year suggested they originated from within ...

New research on the Uranian moon Ariel suggests the icy world may be hiding a deep secret. Credit: NASA / JPL Scientists think one of Uranus' moons may once have had an ocean roughly 100 miles deep — ...

A gravitational and geological model of Uranus’s moon Ariel concludes that the small, icy world once hid a subsurface ocean more than 100 miles, or roughly 170 kilometers, deep, according to planetary ...

Uranus’s tiny moon Ariel may have had a subsurface ocean that made up around 55% of its total volume. By mapping craters, crags, and ridges on the moon’s surface, planetary scientists modeled how ...

The discovery could supply an answer to a mystery surrounding this Uranian moon that has perplexed scientists: the fact Ariel's surface is covered with a significant amount of carbon dioxide ice. This ...

The major clue to a subsurface ocean comes from Ariel’s frozen surface. Ariel’s surface is geologically the youngest of Uranus’ 28 known moons. It is largely covered by water, carbon dioxide and ...

Our Solar System, like a sneaky little hobbit, seems to have stuffed its pockets full of hidden oceans. Jupiter, Saturn, Uranus, and Neptune all have moons astronomers think might be harboring liquid ...

Add Yahoo as a preferred source to see more of our stories on Google. Ariel, one of Uranus' icy moons, may once have concealed a vast ocean more than 100 miles (170 kilometers) deep beneath its frozen ...

Ariel, Uranus’s fourth largest moon, is thought to be made of equal parts rock and ice. A new computer model developed at the University of Texas Institute for Geophysics could be used to detect ...
