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 …

This episode features an interview with Dr Julia Healy, from ASTRON, where she works as part of the MHONGOOSE survey team.

This is episode 60 of the Urban Astronomer podcast! Is that a milestone? Sure, but we'll save the party hats for episode 75.

It's another Science Explainy Bit episode, and today we answer a question asked by another podcaster while interviewing us for their show. The host wanted to know how the view of southern skies compares to that of the northern hemisphere. I gave a quick answer before we moved on to another topic, but I would have liked to give a more detailed and c…

The Urban Astronomer interviews noted South African amateur astronomer Carol Botha about her science outreach work. Carol has become quite well known on Slooh, the robotic telescope and astronomy service which I know quite well because I've provided a few video streams of eclipses and the like for them over the years.Be warned though, this is a lon…

Today's episode is the first Science Explainy Bit of the season, and it's another basic, classic topic: Leap Years. As a reminder, I love looking at the questions that seem simple because we think of them as the sorts of things that children ask their parents, but the thing about these questions is that they never are simple. These are things that …

At long last, the third season of the Urban Astronomer Podcast has kicked off! We thought the last season went so well that we've decided to keep things much as they are, with perhaps the occasional news segment added in whenever something interesting has happened. So for the most part, that means twelve episodes, alternating between interviews wit…

This is just a short note to let you know that we're still here, and that the new season launches next week! Long-time listeners have been waiting for this since February, but I don't think there's anybody left on Earth who couldn't guess which world-changing event caused our schedule to slip!Still, after eight weeks in lock-down, it's time to star…

Since our last episode aired, in early December last year, I've had people ask me when the third season will begin. Well the good news is: Soon! Guests have been booked, interviews will be recorded over the next few weeks, and science explainy bits... well. That's where you come in! If you've got questions you'd like to hear answered in one of the …

The Urban Astronomer Podcast's season 2 finale examines the colours of stars, and ponders what it's actually like out in spaceAllen Versfeld

In this episode, we interview Nicole Thomas, a PhD student at the University of the Western Cape with an interest in the evolution of galaxies, and the super-massive black holes that lie within. We recorded this conversation only a week ago, and I really enjoyed speaking to her. I found her childhood interest in how the universe worked very relatab…

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 …

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 noti…

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, …

In episode 48 of the Urban Astronomer Podcast, we're doing another Science Explainy bit!

Welcome to another Science Explainy Bit episode of the Urban Astronomer Podcast. Today we try to figure out just what an "orbit" actually is. Is it really as simple as they said in primary school? How does gravity, which normally pulls things down, work to keep the Moon in space? Download this episode now, to find the answer, and also learn a littl…
