When We Find Life: Science, Society, and Survival

What happens after we discover life beyond Earth? The question is no longer "if," but "when"—and how humanity responds could shape our future. Host and planetary astronomer Franck Marchis welcomes Martin Dominik, one of the authors of a new white paper on the societal, political, and philosophical challenges we'll face once alien life is confirmed. From public communication and policy to our collective sense of identity, this discussion explores how to prepare for the biggest discovery in human history. 📄 Read the paper: https://arxiv.org/abs/2507.11587  📰 Universe Today article: https://www.universetoday.com/articles/scientists-are-planning-for-life-after-finding-aliens (Recorded 18 September 2025.)
