Spooky Shadow Gives Jupiter a Giant Eye: This trick that the planet is looking back at you is actually a Hubble treat: An eerie, close-up view of Jupiter. Hubble was monitoring changes in Jupiter&#x27;s immense Great Red Spot storm, when the shadow of the Jovian moon, Ganymede, swept across the center of the storm. This gave the giant planet the uncanny appearance of having a pupil in the center of a 10,000 mile-diameter &quot;eye.&quot;  Image Credit: NASA/ESA/A. Simon (Goddard Space Flight Center)
