Photo Composite of Suspected Water Plumes on Europa (Annotated)
This composite image includes data from Hubble’s Space Telescope Imaging Spectrograph, which shows suspected plumes of water vapor erupting at the 7 o'clock position off the limb of Jupiter's moon Europa. The image of Europa, superimposed on the Hubble data, is assembled from data from the Galileo and Voyager missions.
