The deadly molecule that could signal alien life | Clara Sousa-Silva

Clara Sousa-Silva is a quantum astrochemist researching molecules that could indicate life beyond Earth. In this conversation, she presents a compelling case for phosphine, a smelly and poisonous molecule, as a potential biosignature on Venus. Sousa-Silva discusses the challenges of identifying atmospheric signatures, especially differentiating biological from non-biological sources. Her insights into how phosphine could point to life in the clouds of Venus open new possibilities in the search for extraterrestrial ecosystems.
