Summary

Spewing lava and belching noxious fumes, volcanoes seem hostile to biology. But the search for life off-Earth includes the hunt for these hotheads on other moons and planets, and we tour some of the most imposing volcanoes in the Solar System. Plus, a look at how tectonic forces reshape bodies from the moon to Venus to Earth. And a journey to the center of our planet reveals a surprising layer of material at the core-mantle boundary. Find out where this layer was at the time of the dinosaurs and what powerful forces drove it deep below. Guests: Samantha Hansen – Geologist at the University of Alabama Paul Byrne – Associate professor of Earth and Planetary Sciences at Washington University in St. Louis Robin George Andrews – Science journalist and author of “Super Volcanoes: What They Reveal about Earth and the Worlds Beyond” Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network.
