Under-GROUND oceans? Probably not; the current estimates for Europa indicate that the surface is probably ice, with perhaps oceans beneath the ice. If the oceans are made of water rather than some more exotic liquid, then there's at least a possibility that life might exist in that ocean.
Possibly. Europa has an ocean of liquid water under its icy crust, which might have light.

Europa possibly, has a liquid ocean under the surface ice.
Europa, a moon of Jupiter, has a frozen surface with the possibility of a liquid ocean under the surface.
europa's atmosphere consists of oxygen. also, under it's icy surface, is an ocean of liquid water.
Europa, which is one of Jupiter's moons.
Under the ground or ocean,it is mostly under in the ocean
Europa is the moon of Jupiter which contains liquid ocean or H2o
There is a hidden ocean on Europa as found out by NASA, manifested as churning seas beneath its icy surface.
Europa is the moon that could possibly contain a liquid ocean under its icy surface, and it could possibly be liquid water, or H2O!
Jupiter's moons - Europa and Ganymede possibly have oceans of liquid water under their crust. Saturn's moon - Enceladus also has a possible ocean of water under it's crust.
I have read somewhere that scientists think that europa may have an underground ocean.
