Icy Caps
I have read somewhere that scientists think that europa may have an underground ocean.
A thick layer of ice
Europa - a moon of Jupiter.
Scientists believe that there is liquid water, under the crust of Europa.
The scientists think that Europa can have the life on it.
active volcanoes Ice several miles thick, and oceans of liquid water beneath the ice.
Many scientists believe that Europa may hold water, or at least ice which could mean there is a possibility of life on one of Jupiter's moons.
europa is Jupiter's moon. Jupiter has 4 moons, and Europa is one of them.
An icy surface.
The moon you are referring to is Europa. Europa is covered in a layer of ice, and its surface appears cracked due to tectonic forces caused by gravitational interactions with Jupiter and its neighboring moons. Beneath the icy crust, scientists believe there may be a subsurface ocean that could potentially harbor life.
A saline ocean beneath it's crust.
As far was we know the development requires water in its liquid for to be present and a source of energy to supply/drive chemical reactions. We know that deep down Europa has a liquid layer (of water) and the geysers of this water into space proves that there is energy in Europa's core.
