https://youtu.be/zWTL8mzta_E Host: Fraser Cain ( @fcain ) Special Guest: Historically, scientists using spectrographic analysis to study exoplanet atmospheres have considered oxygen and methane as two key biosignatures when identifying "life-friendly" planets. But could nitrous oxide (N2O) — aka "Laughing Gas" — also be a reliable biosignature? A recent paper published in the October, 2022, Astrophysical Journal (https://iopscience.iop.org/article/10...) explains why N2O can — and should — be included as a biosignature gas. Tonight we are pleased to welcome the paper's lead author, Dr. Eddie Schwieterman, astrobiologist at UC Riverside, to discuss why N2O is an indicator of life.   Dr. Eddie Schwieterman is an Assistant Professor of Astrobiology in the Department of Earth and Planetary Sciences at the University of California, Riverside. He earned his undergraduate degrees in physics and astrophysics from the Florida Institute of Technology and his PhD in astronomy and astrobiology from the University of Washington in Seattle.   Dr. Schwieterman studies the climate, atmospheric chemistry, geochemical evolution, and spectral appearance of terrestrial (rocky) planets. His research specifically focuses on the habitability and potential biosignatures of exoplanets.

Weekly Space Hangout — January 4, 2023: Dr. Eddie Schwieterman Discusses Nitrous Oxide as a Biosignature

Our guest is Dr. Eddie Schwieterman, an astrobiologist and astronomer interested in studying planetary habitability and remote biosignatures to uncover the distribution of life in the Universe. Eddie received his undergraduate degrees from the Florida Institute of Technology in Physics and Astrophysics and his PhD in Astronomy and Astrobiology from the University of Washington in Seattle, working with the Virtual Planetary Laboratory and his advisor Dr. Victoria Meadows. After receiving his PhD, Eddie spent three years as a NASA Postdoctoral Fellow at the University of California, Riverside working with the Alternative Earths team led by Dr. Timothy Lyons. Dr. Schwieterman is currently a postdoctoral fellow at Georgia Tech and will be starting as an Assistant Professor at the University of California, Riverside next month.Check out our website for the full transcript of this podcast, plus the full YouTube version of this episode: https://astrobiology.nasa.gov/ask-an-astrobiologist/episodes/40/
