The Eye of Jupiter


jupitereye_0Not really. The trick is that the planet seems to be looking back at us because Hubble happened to catch the shadow of Ganymede, Jupiter’s largest moon, as it moved across the Giant Red Spot. Hubble was monitoring changes in that huge storm last April when the moon’s shadow moved across the center of the storm. For a moment, Jupiter became Cyclops.
