#2For those expecting to see an actual image, this is the closest thing to a photo from NASA:
http://www.nasa.gov/content/goddard/water-vapor-over-europa/
They note: "Hubble didn't photograph plumes, but spectroscopically detected auroral emissions from oxygen and hydrogen."

For an amazing photo of Europa with Io's volcanic plumes in view, see this older photo from 2007: http://photojournal.jpl.nasa.gov/jpeg/PIA10103.jpg

#3As warm as the word vapor may sound it is actually really cold. Europa's oceans, if they exist, are -50°C and lower.

#4Checkout the movie Europa Report to feed your SciFi fantasies.

#5Please forgive my ignorance. What makes Europa more likely to contain life than other moons thought to contain oceans like Callisto, Ganymede, Titan, Enceladus ... ? [1]

And this is why NASA's Planetary Sciences division should not suffer huge budget cuts.

Doesn't water freeze and become ice at 0°C?

#8This is an awesome phenomenon. Yesterday we had a post re panspermia:

Now think of an Europa with simple bacteria living in the water under the ice. These events are like cosmic sporulation: long strings of frozen droplets that could contain organisms, ejaculated into space like spores in the wind.

You can make supercooled water in your freezer.
