What could be under the surface of Europa?

Under the surface of Europa, one of Jupiter's moons, there is strong evidence suggesting the presence of a subsurface ocean composed of liquid water, potentially in contact with a rocky seafloor. This ocean may harbor essential chemical compounds that could support life. Additionally, the ocean is thought to be maintained in a liquid state due to tidal heating from gravitational interactions with Jupiter. The combination of water, energy, and nutrients raises intriguing possibilities for extraterrestrial life.
