Dead or Alive (EP4)
Résumé de l'épisode 4
The worlds that surround our planet are all made of rock, but there the similarity ends. Some have a beating geological heart, others are frozen in time. Professor Brian Cox travels to the tallest mountain on Earth, the volcano Mauna Kea on Hawaii, to show how something as basic as a planet's size can make the difference between life and death. Yet the fifth wonder in the series isn't on a planet at all. It's on a tiny moon of Jupiter.
