I think that the odd form of that URL may be causing problems. Here's what the Discussion page says: ---- This article states: "It has an outer layer of water ice thought to be around 100 km thick then later says: "...based on this and on the calculated amount of heat generated by Europa's tides it is predicted that the outer crust of solid ice is approximately 10-30 km thick, which could mean that the liquid ocean may be as much as 90 km deep underneath." Am I correct in assuming that the first number refers to the thickness of the water AND the ice, combined? Not just the "water ice"? ---- I'm pretty sure it's just a mistake, but don't yet feel qualified to go around fixing encyclopedias, even wiki ones. Thanks much for the other info. Here's a follow-up on the eclipse question: Would any of the sun's corona be visible from Europa, while the eclipse was at maximum effect? In other words, would Jupiter appear just as a black hole in an otherwise starry sky, or would it appear to have a ring around it? This is a tougher question, I think, but considering that Jupiter is much bigger and the sun is much smaller from that vantage point, I tend to think there would be nothing visible in that direction but blackness. Or perhaps just reflected light from other moons. --Mark __________________________________ Do you Yahoo!? Yahoo!
