This color image of the Earth was obtained by the Galileo spacecraft on Dec. 11,
     1990, when the spacecraft was about 1.5 million miles from the Earth. The color
     composite used images taken through the red, green and violet filters. Africa
     stretches from the center to the top of the picture with the Arabian Peninsula off to
     its right. The white, sunlit continent of Antarctica is at the bottom. This is a frame of
     the Galileo Earth spin movie, a 500-frame time-lapse motion picture showing a
     25-hour period of Earth's rotation and atmospheric dynamics.
