The Fountains of Enceladus
EccentricAnomaly writes "Cassini has observed fountain-like plumes from the warm fractures near Enceladus' south pole. This confirms what had been suspected from an image taken last January. And seems to point to these cryo-volcanoes as being the primary source of Saturn's E-ring. There are also more images available from Cassini's raw images archive."
Well said - it is not true (and it's unfair, reall) to say that the Cassini team is "slow" to post images.
