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:

- dmead 13y agodoes this mean it's pure conjecture that it was a water plume? my idea of a water plume would say that it's sub surface ocean water getting ejected out of the surface. this evidence seems like it could have been water knocked up by a meteor impact or some other mechanism to get the surface ice into orbit.
- tokipin 13y agoit's my understanding that the gravitational "torsion" from Jupiter alone is enough to do all sorts of things (like keep a planet thermally active)
