This is an artist's concept of the moon Europa, at right, with water-ice plumes erupting from its lower left limb at the 7 o'clock position. In the background, to the left, is Jupiter's orange, volcanic moon Io, and to the left of Io is Jupiter. Io's shadow appears in the center of Jupiter's face, left.
