Talking About Tides

Astrobiology Magazine presents its latest podcast with our host Simon Mitton. In this interview, Brian Jackson, a NASA Earth and Space Sciences Fellow in the Department of Planetary Sciences at the University of Arizona, explores the importance of tidal heating in determining the habitability of planets. Tidal heating, which is generated by orbiting a massive gravitational body like a star or giant planet, can heat up a planet or moon. If there is too much tidal heating, though, the resulting volcanism can create torrid conditions unsuitable for life.
