This latest edition of the science documentary series looks at the parallels between volcanos on Earth and volcanos in other parts of the solar system.
We follow the story of volcanos in three different places: Mars, home to extinct volcano Olympus Mons, the highest peak in the solar system; Jupiter’s moon Io, which has the solar system’s most violent volcanic activity; and Saturn’s moon Enceladus, an icy world that has geysers that erupt from a hidden ocean.
Here we can learn from these volcanos about how life on Earth was able to develop. For example, Olympus Mons formed in a similar way to the volcanos in Iceland.
Horizon: Space Volcanos is on BBC Two at 21.00.
