Rather than flowing magma, geological shifts on icy moons are produced by melting ice. The ice shells coating these moons wax ...

Earlier this year, a team of astronomers discovered a new moon of Uranus that is minuscule, with a diameter of about 10km.

Simulations show that subsurface oceans on small moons may hit boiling conditions, potentially creating features like Miranda’s distinctive ridges.

The outer planets of the Solar System are swarmed by ice-wrapped moons. Some of these, such as Saturn’s moon Enceladus, are ...

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 outer planets of the solar system are swarmed by ice-wrapped moons. Some of these, such as Saturn's moon Enceladus, are ...

For researchers at the University of Idaho, spotting a moon 6 miles wide orbiting Uranus, a staggering 1.8 billion miles from Earth, may actually be easier than finding a white cat in a snowstorm. A ...

But on larger icy moons, the ice layer may break up before the water boils, preventing the formation of a boiling ocean.

Far from the warmth of the Sun, some of the coldest-looking worlds in the solar system may be hiding the hottest surprises.
