The Supermassive Podcast

Backed by the Royal Astronomical Society—an institution that has been around since 1820—The Supermassive Podcast carries some serious credentials. Science journalist Izzie Clarke and astrophysicist Dr. Becky Smethurst host biweekly episodes that blend current research with historical gems from the RAS archives. Dr. Robert Massey pops in with stargazing tips, which is a nice practical touch for listeners who actually want to go outside and look up. The show covers topics like gravitational physics, multiverse theory, and temporal mechanics, but presents them in a way that feels conversational rather than academic. Over 108 episodes since 2020, it has earned a 4.6 rating from 316 reviews. The British perspective is refreshing if your podcast diet is heavily American—there is a slightly different emphasis on international collaborations and ESA missions alongside NASA coverage. Produced by Boffin Media and Richard Hollingham, the audio quality is consistently high. Members of The Supermassive Club get ad-free listening and exclusive forums, but the free version is perfectly complete on its own. This one is ideal for listeners who want academic rigor wrapped in genuinely accessible conversation.
