Urban Astronomer

The Urban Astronomer Podcast is a twice-monthly show about South African astronomy and astronomers. Episodes alternate between interviews, and our regular Science Explainy Bits. The interviews feature professional and amateur astronomers, telescope engineers, and anybody else who has a connection to astronomy in South Africa. The explainers are just Allen Versfeld taking deep dives into the very basics of astronomy and physics. More often than not, he finds them to be way more complex than they look–the explanations we all got as small kids are hopelessly oversimplified, if not plain wrong.

It’s a fun, casual show that’s now in its third season and has been running (with breaks) since 2017. Give it a listen and let us know what you think!

ask a spaceman podcast

“Ask a Spaceman” is a show hosted by Paul M. Sutter, a theoretical cosmologist as well as the author of two books: “Your Place in the Universe” and “How to Die in Space”. The show is composed of short episodes in which Paul answers questions sent by fans regarding space exploration, astronomy and cosmology. Sometimes, the episodes are structured in series which allows him to touch on complex topics such as quantum mechanics in more detail.

Moreover, Paul has a great sense of humour and his charisma makes the show incredibly entertaining. What I like the most about this show is Paul’s ability to explain complex topics in an accessible way, using simple and well-structured analogies.

With almost 200 episodes available, “Ask A Spaceman” is an absolute delight for anyone who loves space and the many mysteries surrounding the universe we live in. It definitely makes my commute to work a lot more enjoyable. Highly recommended!
