This might look like a splash of cream in your coffee -- but in fact it's Jupiter's Great Red Spot, imaged by NASA's Voyager 1 spacecraft.
It's swirling rather faster than the spoon in your cup could manage, too -- in fact, the winds that carry the clouds that create the spot move in excess of 400 mph, creating raging storms three and a half times the size of Earth. Gulp. The image was actually created recently using three black and white negatives captured decades ago. [NASA]
