Impossible exoplanets and Rhetoric

Socrates Address by Belgian artist Louis Joseph Lebrun 1867

This is episode 62 of the Urban Astronomer Podcast, our first release of 2022. Happy New year! In this episode, we’re doing something a little different. Traditionally we alternate between interviews and Science Explainy Bits, but the second segment here is a bit more philosophical than usual, and ran a bit short, so I’ve added something a bit more topical – some astronomy news! Impossible exoplanet As covered previously on this website, the science media were very excited to report … Continue reading →

How do we know what things in space are made from?

This is episode 60 of the Urban Astronomer podcast! Is that a milestone? Sure, but we’ll save the party hats for episode 75. Today we’ll just get on with the job at hand, and bring you a science explainy bit. Today’s question: How can astronomers be so certain about what things in space are made from? On Earth it’s relatively easy to send geologists out to different places with their hammers, and have them collect samples from interesting rock formations … Continue reading →

Interview with Dr Tana Joseph

Dr Tana Joseph

This is episode 9 of the 2nd season of the Urban Astronomer Podcast, featuring an interview with Dr Tana Joseph.  It’s been an interesting two weeks since the last episode – I’ve settled further into my new home and adjusted from rural to suburban life. What I gained in access to basic utilities and saving several hours off my commute has been paid for with a loss of the sky – not to light pollution, but to a canopy of … Continue reading →

Why did I defend the geocentric model?

Diagram of Copernicus's answer to the geocentric system

In this eighth episode of the second season, I defend my defense of the Ptolemaic geocentric system of crystal spheres! I hadn’t even realized till I started recording that this is our 50th ever episode. I really should be so blown away that I’ve kept things going this long, but I’m not, somehow? Perhaps it’s just become a habit, and I stopped noticing milestones! But anyway, 50 episodes, I think that’s pretty amazing and I’m very proud to have made … Continue reading →

Interview with Dr Jarita Holbrook

Dr Jarita Holbrook

In Episode 7 of the second season of the Urban Astronomer Podcast, I chat with Dr Jarita Holbrook of the University of the Western Cape about her interest in cultural astronomy. This was one of the longer and more interesting interviews of my career, and our conversation continued for some time after the microphones were turned off! Unfortunately, the audio quality isn’t as good as I’d hoped. There’s a terrible echo on my voice which comes and goes as the … Continue reading →
