Summary

In this World Science Festival conversation, Brian Greene interviews astronomer David Kipping about the search for exomoons—moons orbiting exoplanets. Kipping begins by tracing the history of exoplanet discovery, from early false claims to the first confirmed detections around pulsars and sun-like stars, and the subsequent transit method that enabled the Kepler mission to find thousands of exoplanets. He explains how exomoons could be detected via transit timing variations and duration variations, and discusses the potential for moons to host life, as they might be more numerous and stable than planets. Kipping highlights the current state of exomoon research, including the controversial candidate Kepler-1625b, and outlines future prospects with missions like the Roman Space Telescope. The conversation emphasizes the importance of exomoons as the next frontier in the search for habitable worlds beyond our solar system.
