Eight distant worlds hold secrets that still puzzle scientists and spark endless curiosity. Each moon offers a strange allure ...

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

Rather than flowing magma, geological shifts on icy moons are produced by melting ice. The ice shells coating these moons wax and wane in response to forces generated by the planet they orbit and by ...

Researchers look into the stresses caused by oceans in the surrounding shells of icy moons, and find that some can release ...

While the crater-pitted moon may appear geologically dead, researchers have discovered more could be going on under its icy ...

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

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.

It takes light a single day to travel 16 billion miles. The Voyager 1 probe will need a little longer, just 49 years.

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 ...
