The biggest storm in the solar system may be slowly dwindling, but as can be seen from this view, even the shadow from Jupiter's biggest moon cannot engulf the mighty Great Red Spot.

Imaged on April 21, 2014, by the Hubble Space Telescope, Ganymede orbited between the sun and Jupiter, casting a dark shadow over the gas giant's upper atmosphere. When the timing was right, the shadow drifted across the famous storm, giving the Great Red Spot what appears to be a dark pupil in its unblinking eye. "For a moment, Jupiter ‘stared' back at Hubble like a one-eyed giant Cyclops," writes the NASA Goddard Space Flight Center image release.

The Great Red Spot was discovered in by Gian Domenico Cassini in 1665 and it represents a long-lived anticyclonic storm that is thought to have a lifetime spanning 300 to 400 years. Measuring over 10,000 miles wide, the storm could easily engulf the Earth. However, the storm is slowly dwindling, losing 15 percent of its diameter between 1996 to 2006.
