Photo Composite of Suspected Water Plumes on Europa (Annotated)
Europa
The position of Jupiter and Europa changes as they and Earth travel on their orbits through the solar system. Europa, orbiting Jupiter, was approximately 4.3 AU (400 million miles or 640 million kilometers) from Earth at the time of these observations.
F25SRF2 (150nm UV)
This image was made by HST's STIS MAMA instrument with the F25SRF2 filter (150nm UV). Color was added to the grayscale image using a blue color mapping. A separate grayscale image of Europa, produced using data from the NASA Galileo and Voyager missions, was superimposed to scale.
Blue: F25SRF2
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.
