I'm growing more skeptical about the possibility of life on Europa.
With frozen acidic compounds detected on the surface of Europa
by the Galileo probe I'm more inclined to believe that an acidic ocean lies beneath the icy surface.
That to me rules out all macroscopic, complex life existing in the
Europan oceans.
There might still be simple microscopic life in Europa's acidic oceans,
but even there I'm growing doubtful about it.
