A realistic attempt to reconstruct the early history of the solar system. The authors chose a procedure which reduces speculation as much as possible and connects the evolutionary models as closely as possible to experiment and observation.
The pictures in this publication are a part of the rich harvest of information returned by Voyager 1. These images are of great beauty as well as great scientific interest, reminding us of the breathtaking dimensions of the solar system we inhabit.
