In the search for life beyond Earth, subsurface bodies of water in our outer solar system are some of the most important targets. That’s why NASA is sending the Europa Clipper spacecraft to Jupiter’s moon Europa: There is strong evidence that under a thick crust of ice, the moon harbors a global ocean that could potentially be habitable.

But scientists believe the ocean isn’t the only water on Europa...

Ice-penetrating radar data from Greenland suggests that shallow water pockets may be common within Europa’s ice shell, increasing the potential habitability of the Jovian moon’s ice shell.

Europa is a prime candidate for life in our solar system, and its deep saltwater ocean has captivated scientists for decades. But it’s enclosed by an icy shell that could be miles to tens of miles thick, making sampling it a daunting prospect...

Researchers have built the world’s first physics-based computer simulation of oxygen transport on Europa, finding that it’s possible for oxygen to drain through the moon’s icy shell and into its ocean of liquid water — where it could potentially help sustain alien life — by hitching a ride on salt water under the moon’s ‘chaos terrains.’ The results show that not only is the transport possible, but that the amount of oxygen brought into Europa’s ocean could be on a par with the quantity of oxygen in Earth’s oceans today.

This theory has been proposed by others, but the researchers put it to the test by building the world’s first physics-based computer s...

Discovery could point to a new class of ‘stealth’ ocean worlds. A Southwest Research Institute scientist set out to prove that the tiny, innermost moon of Saturn was a frozen inert satellite and instead discovered compelling evidence that Mimas has a liquid internal ocean...
