Reply to comment by ChickenChimneyChanga in TIL the largest moon in our solar system, Ganymede, is larger than the planet of Mercury by Jugales

Too damn cold for any but water ice. Liquid water unless proven to exist is not there.

Surface temp 90 to 160 K. 294 K is 70 Deg. F. So far below frozen water it's not even realistic to be liquid.

I think the theory is that if you go deep enough, it gets warmer due to interior heating. Plus the added pressure that deep could help in melting the water. I think you may also not be considering that salty water changes phases differently than pure water

There is NO empirical evidence existing or real that Ganymede has liquid water. Prove that it does, which cannot at this time. Empiricists consider the facts, and learn more. But we know suppositions compared to empirically tested and confirmed truths. Anything else is hardly en pointe to understanding events.
