An artistic representation of Europa in cross-section. Various processes, from the seafloor to the surface are indicated, providing an integrated perspective on how the seafloor, ocean, and ice shell could yield biosignatures detectable on the surface by a landed spacecraft. Astronomy: Roen Kelly, after K. Hand et al./NASA/JPL

Life on Europa could exist -
1. Around hydrothermal vents near the ocean floor,
2. Just below the icy surface,
3. Or up and down the ocean waters.
One study showed that irradiation of ice on Europa's surface could create enough oxygen and peroxide, which could oxygenate the ocean within a few million years, allowing the existence of complex, multicellular lifeforms.
