The UK's #1 space podcast.Themes and summary (AI-generated based on podcaster-provided show and episode descriptions):
➤ Astronomy and astrophysics explainers • listener Q&A on space physics • black holes, gravity, spacetime, time travel • solar system worlds and missions • solar storms, asteroids, planetary defense • aliens/SETI • stargazing and dark-sky issuesThis podcast is a UK-made space and astronomy show hosted by science journalist Izzie Clarke and astrophysicist Dr Becky Smethurst, with regular contributions from Dr Robert Massey. Across the episodes, the hosts explain current astrophysics and planetary science in an accessible way, often bringing in researchers, engineers, and occasionally astronauts to add specialist context. A recurring format is audience-driven: the team answers listener questions that range from playful “what if?” scenarios to detailed queries about established and speculative science.
Much of the content focuses on understanding how the universe works at different scales. Listeners will hear discussions of fundamental physics such as gravity, spacetime, the nature of time, and why the speed of light is a limiting factor. The show also returns frequently to black holes and related extremes, including jets, mergers, and what their behavior might imply for the wider cosmos. On the cosmology side, it explores large-scale structure (like the cosmic web), the early universe, and ideas such as inflation and the multiverse, while also tackling how scientists gather evidence for or against these models.
Solar system science is another major thread, with attention to planets and moons, their histories, and how we study them through missions. Topics include planetary environments and evolution (for example Mars’s past water, Venus’s harsh conditions, and Mercury’s exploration), as well as hazards and near-Earth concerns such as asteroids and major solar storms. Space exploration and space technology appear regularly through conversations about sample-return missions, satellite risks, and the practicalities of human exploration, including debates about the role of astronauts versus robots and AI.
The podcast also touches on observational astronomy and the human relationship with the sky: stargazing guidance, light pollution and “dark skies,” and how celestial cycles connect with culture and archaeology. Overall, it combines news-adjacent science, historical context, and listener Q&A to cover both the methods of modern astronomy and the big questions that motivate it, including the search for extraterrestrial life and how a detection might be handled.
