Big Picture Science - Life on Venus?
Have scientists found evidence of life on
Venus? Known for its scorching temperatures and acidic atmosphere, Earth’s twin
hardly seems a promising place for living things. But could a discovery of
phosphine by researchers at MIT point to a high-altitude biosphere on this
nearby world?
Guests:
- Clara Sousa–Silva - Research scientist in MIT's Department of Earth, Atmospheric and Planetary Sciences. She and Sara Seager co-authored a paper in January 2020 titled, “Phosphine as a Biosignature Gas in Exoplanet Atmospheres”
- Sara Seager - Professor of physics and planetary science, Massachusetts Institute of Technology and author of “The Smallest Lights in the Universe”
- Nathalie Cabrol - Planetary Scientist and Director of the Cal Sagan Center at the SETI Institute
