In Praise of Volcanoes

Astronomer Michelle Thaller talks with Ashley Davies, a research scientist at the Jet Propulsion Laboratory, about the importance of volcanoes in the creation of Earth and how the study of volcanos in space can help us understand life here. Davies has journeyed to remote volcanos like Mt. Erebus in Antarctica and Erta Ale in Ethiopia as a way to help map volcanos like those on Jupiter’s moons, Io and Europa, and in turn come that much closer to understanding how life began.
