Space Volcanoes 9PM BBC2

This is new and NOT a repeat. :)

 

The astounding, terrifying science of volcanos is something that ensnares our imagination from schooldays, with history lessons on Pompeii and science programmes screened on cabinet TVs showing the roaming red plastic that is molten lava. But as this explosive Horizon will prove, Vesuvius and Etna are mere anthills compared with their cosmic cousins, both extinct and active. The 25km-high Olympus Mons on Mars, for instance, or the peaks that puff gas 300km above Jupiter’s moon Io.

A team of volcanologists in Iceland (who presumably are on hand to pronounce Eyjafjallajokull) still manage to find similarities – and we learn how these seismic scapegoats are actually essential to life.
