Watch BBC: The Planets – 01 – Different Worlds (1999) Documentary Online


Different Worlds. The eight known planets of our solar system are each so different from each other that they give no easy answers to how the universe was formed.

Clues to the birth and evolution of the solar system lie scattered throughout the solar system, on the faces, in the orbits and rotations of the planets and their moons and among the great belts of asteroids, comets, and lost worlds left over from the beginning. Distance, time and technology handicap us as we collect pieces of the story — but we’re getting there.

Slowly but surely, we are beginning to understand.
