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 →

Saturn’s Rings older than we thought

Saturn's Rings, as seen by Voyager 1

One of the oldest mysteries in modern astronomy is the age of Saturn’s Rings. The Cassini mission seemed to have settled the question once and for all, but now a team of researchers have just claimed that things might not be so clear-cut. Cassini showed that the rings were mostly made up of clean ice particles. There wasn’t much of the dust and organic gunk you’d expect to accumulate over time. This meant that the rings couldn’t have been around … Continue reading →
