We cannot be certain (yet!) but current theories speculate that the moon Europa may be covered with ice, and that beneath the ice there might be oceans. There do appear to be ridges in the surface, which might be caused by cracks forming in the ice and then the liquid water beneath freezing as the ice sheets come back together.

Which Galilean moon is composed mostly of nitrogen?
None of Jupiter's Galilean moons are composed mostly of nitrogen. Ganymede is primarily composed of water ice, while Callisto, Europa, and Io are composed of a mix of rock and ice. Nitrogen is more commonly found in the atmosphere of Titan, a moon of Saturn.
What Galilean moon has the smoothest surface?
The Galilean moon with the smoothest surface is Europa. Its icy exterior is characterized by a relatively featureless landscape marked by a network of cracks and ridges, indicating a subsurface ocean beneath the ice. This smooth surface suggests geological activity, which may play a role in maintaining its pristine appearance. Europa is of particular interest for astrobiology due to the potential for life in its ocean.
What is the farthest Galilean moon from Jupiter?
Callisto with a semi major axis of 1,882,700 km. See related question.
Europa is a moon on which planet?
Europa is a moon of the gas giant Jupiter. It is one of Jupiter's four largest moons, known as the Galilean moons, and is believed to have a subsurface ocean beneath its icy crust.
Which of the Galilean moons has a grooved terrain?
Ganymede is the Galilean moon known for having a grooved terrain. These grooves are believed to be the result of tectonic activity on the moon's surface.
What Galilean moon has the shortest sidereal period?
twenty juan
Is titan a galilean moon?
No. The Galilean moons are the four largest moons of Jupiter (Io, Europa, Ganymede, and Callisto) discovered by Galileo. Titan is the largest moon of Saturn, discovered by Christiaan Huygens.
