Small icy moons may have hidden oceans that briefly boil under thick ice. Changing pressure inside these moons shapes their ...

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

Several small worlds beyond Jupiter are not just frozen rubble. Beneath their shining skins, many hide oceans of liquid water ...

Out in the cold, distant reaches of our solar system, many moons are wrapped in thick layers of ice. At first glance, these ...

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

Small icy moons in the outer reaches of our solar system may hide boiling oceans underneath their surfaces, a new study finds.

There are several frozen moons in our solar system, orbiting the gas giants. Some of them, despite having temperatures that would make Antarctica feel tropical, have liquid water under the surface.

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

Unlike geology on Earth, which is driven by the movement of deep rock, the action on icy moons is powered by the dynamics of water and ice.

Saturn stunned skywatchers on 23 November when its iconic rings seemed to vanish, leaving the planet looking strangely bare. Astronomers confirmed not ...

That’s also true for the other moons that provide the gravitational stress. As a result, the internal oceans may actually ...

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