Drifting Signals: New Boundaries for Radio Technosignatures

In a new study published in the Astronomical Journal, researchers used the known population of exoplanets to set better thresholds for planetary effects on signals from ETIs (extraterrestrial intelligences). Megan Grace Li, a Ph.D. student at UCLA in UCLA SETI, conducted this research as a National Science Foundation Research Experience for Undergraduates intern in the Breakthrough Listen project at the Berkeley SETI Research Center. Join Megan as she chats with Beth Johnson about her work and what it means for the future of SETI searches. (Recorded 30 November 2023.)
