Urban Astronomer avatarPosted on by

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 →

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 →

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 →

Interview with Dr Daniel Cunnama

Welcome to the 3rd episode of the Urban Astronomer Podcast, season 2, featuring Dr Daniel Cunnama. We almost didn’t make it this week, thanks to a major technical hitch, but we worked around it and here we are. If you listened to the last episode, then you’re probably expecting this to be an interview episode, featuring Dr Rosalind Skelton of the South African Astronomical Observatory. I spoke to her in June last year and we recorded an interview specifically for … Continue reading →
