    Ice fishing on Europa? I know who I'd pick for my crew. Too bad two out of three are dead- I'll still go with the third.

    I remember seeing something about how this basically happened on Earth as well, during a kind of super ice-age. The solar wind hit the water ice on the surface, which liberated a whole lot of oxygen, which led to a massive explosion in the complexity of life on Earth once the ice melted.
    Before that, life was limited to very simple organisms.

    Europa is very far away. At the speed of light, it takes an hour to send a message there and an hour to receive a message back.

    So there could be fish, but maybe not? Let's send some salmon there and populate those seas, just in case. By the time we manage to build a colony there, we should have plenty of fish to create some rather delicious cedar plank filets for the people to enjoy...

    There will be McDonalds for those that do not like salmon filets.

    "So how does the oxygen get into the water? It's created when charged particles from Jupiter's magnetic field hit the ice."

    Annalee, please allow me to suggest a correction. A magnetic field (Jupiter's or otherwise) is not made of charged particles.

    What's going on is that charged particles in the solar wind get trapped by the magnetic field lines. Remember what I said in the LHC article, that charged particles travel in spirals when in the presence of a magnetic field? It's the same thing at work here.

    Charged particles in the solar wind pass through Jupiter's magnetic field (which is rather intense) and get trapped, circulating around the field lines while they (the particles) travel along the field lines (thing of a barber pole).

    Since Jupiter's magnetic field extends as far as Europa and beyond (it's large enough to encompass *all* of Jupiter's moons), these trapped charged particles end up colliding with the ice sheets.

    These collisions are fairly energetic and break the molecular bond between hydrogen and oxygen that exists in water. Hydrogen is much too light to be trapped by Europa's gravitational field and escapes to space (same reason why Earth's atmosphere is not rich in hydrogen), but oxygen is heavy enough to stick around. It's also very chemically reactive.

    As a result of its abundance and due to the tidal stresses that you pointed out, these free oxygen atoms percolate through the ice sheets down into the water below.

    Incidentally, the "charged particles get trapped by magnetic field lines and move along them in spirals" thing is the reason for Earth's aurora borealis.

    As the charged particles travel along the Earth's magnetic field lines, they get more concentrated in the poles (because the field lines are converging there).

    Such high density of charged particles at relatively low altitudes makes for frequent collisions with the atoms in the atmosphere, producing light of various frequencies (colors), hence the auroras.

    @Roklimber: Here's a youtube animation of charged particles moving in a magnetic field.

    In this animation, the particle moves in a *circle* around the field lines (technically, a helix), rather than in a *spiral*, because the particle's energy is constant.

    In real-life situations, the particles continually lose energy due to collisions with the environment and also because they emanate electromagnetic radiation so, as a result, the radii of their helical trajectories decrease, producing helical spirals.
