What, you must be thinking of Oceania.

What, you must be thinking of Oceania.

If you're trying to make 1984 jokes, it's Eurasia, not Europa.

If it's just a geography gag, we could debate for hours on the continental status of both.

[Darvi]

The latter. Never read Orwell.

[FearfulJesuit]

I'd really like to see a source for that statement about aquatic nebulae.

would a cracked article do?

Never. Also in terms of semantics, nebula are clouds. Wouldn't an aquatic nebula be a really big bubble, like a planet that's entirely liquid? Funky.

Europa!

if it orbited closer to the sun.

Europa's got a core of rock, though, hasn't it?

Also, if it orbited closer, what would water of that depth look like? After a few tens of miles down, wouldn't the water start to heat up from the pressure? And so wouldn't you get convection cycles?

It'd also start boiling away because something that small isn't exactly good at holding on to an atmosphere.

[Oliolli]

A watery planet being discussed and nobody mentions Naboo?

[Vorthon]

* Vorthon slaps Oliolli.

Keep yer soft sci-fi outta this!

HERP DERP THE PLANETARY CORE IS HOLLOW AND FULL OF WATER IT MAKES SENSE

Saturn's moon Titan would like to have some words with you

[Vorthon]

1. Titan's far enough out that it's cold enough to hold on to an atmosphere. If you moved it into the habitable zone, it'd lose that nice swaddling blanket of gas.
2. Titan's the second largest moon in the solar system. Europa's smaller than Luna.

[Helgoland]

The latter. Never read Orwell.

Do it, then. It makes for great quoting material

WAR IS PEACE
FREEDOM IS SLAVERY
IGNORANCE IS STRENGTH

What if Europa is just a huge chunk of ice? Like an ice cube, but round, and in outer space.

We've already estabilished that Europa contains water under it's ice layer. Mostly because the ice, while being bloody thick, isn't unbreakable. It cracks and moves, hinting that something underneath is moving it.

Model of Europa's interior showing a solid ice crust over a layer of liquid water or soft ice, a silicate mantle and a metallic core.
