Sun
Since Soho moves along at the speed of Earth
around the Sun, the only way to get 3D is to wait for the Sun itself to
move. Of course, since these images weren't taken simultaneously,
there is some variations between the actual features in each shot, but
overall, the sun is definitely a ball and the major features did not change.
