Speaker: Stephen Mojzsis, University of Colorado
Location: Mondi Seminar Room 2, Central Building
New physical, chemical and dynamical studies show that a biosphere could emerge and persist in the first ~150 million years of the solar system. I will show new approaches in Earth & Planetary studies to untangle the thermal history of the crustal template for life, and explore how the geosphere interacted with a primordial hydrosphere and atmosphere. Although we do not yet understand where, why or how life emerged on our world, we can now answer, when.
