Futureproof with Jonathan McCrea

The Earth’s core was thought to be a sealed vault 3,000 kilometers beneath our feet, isolated from the layers above. But now, new evidence is shaking that assumption to its core. Is the earth’s core leaking? Professor Matthias Willbold from the Department of Geochemistry and Isotope Geology at the University of Göttingen in Germany joins Jonathan to discuss.Also featured, Newsround with Dr Tara Shine from Change by Degrees and Dr Jessamyn Fairfield from the University of Galway.

Are we alone in the universe? Could there be other civilisations out there that we could possibly contact?In 1961, Astrophysicist Frank Drake tried to formulate an equation that could answer these questions.Today, we have finally reached a technological level that allows us to search for signs of life and technology on planets in distant star systems.So, “Is There Anybody Out There?”We’ll be asking that question on this very special episode of Futureproof...Guests:Sean Jordan - Associate Professor in Biogeochemistry and Astrobiology at Dublin City University @SeanFJProfessor Johanna Vos - Astrophysicist specialising in exoplanet atmospheres in Trinity College Dublin @TCD_physicsProfessor Lisa Kalteneger - Professor of Astronomy at Cornell and current Director of the Carl Sagan Institute @KalteneggerLisa
