Fifty-five hundred worlds and counting: The astonishing diversity of exoplanets

Scientists have discovered over 5,500 exoplanets, but they’re just getting started. We dive into the stunning variety of exoplanets beyond our Solar System with Jessie Christiansen, the project scientist for the NASA Exoplanet Archive. But first, The Planetary Society's science editor, Asa Stahl, shares more about the upcoming Habitable Worlds Observatory, a cutting-edge space telescope designed to hunt for worlds that could harbor life. We also give an update on the International Space Station with our senior communications advisor, Mat Kaplan. Stick around for What's Up with Bruce Betts as we discuss the advances in exoplanet detection and share a new Random Space Fact.
