About the Above Image
This image (actually pieced together from multiple images) was acquired on December 8, 1992, by NASA's Galileo spacecraft, as it swung by Earth on its way out to Jupiter. It shows a wonderful but physically impossible view of the Southern Hemisphere. A substantial fraction of the image should be in darkness, even though the image depicts a time near the summer solstice of the Southern Hemisphere. This view was created by patching together a mosaic of several images taken by Galileo over a 24-hour period, and remapping them as they would be seen from above the pole. South America, Africa, and Australia are respectively seen at the middle left, upper right, and lower right.

Of particular interest are the beautiful cloud patterns associated with extratropical cyclones in the storm track ringing Antarctica. This picture is reminiscent of photos of RdishpanS experiments, in which aspects of the general circulation are simulated in a rotating, differentially heated laboratory tank.
