Interview with Nicole Thomas

Portrait of Nicole Thomas

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 relatable, and especially her need to understand what’s going on underneath it all. Sadly, this is the final interview with a … Continue reading →

In episode 48 of the Urban Astronomer Podcast, we’re doing another Science Explainy bit! These segments are where you get to hear my droning voice explain some fundamentals and answer listener questions. Today we get asked why it always is that planets orbit in the same plane, and why the Moon can be seen during daylight. If you like what you hear, don’t forget to tell a friend about the show, and make a small donation on our Patreon account. … Continue reading →

Welcome to the 5th episode of the Urban Astronomer Podcast! We’re well on our way in the grand experiment of deciding how exactly to format the show, and today we’re trying yet another combination! We’ll start off by answering the question first asked in a classic Urban Astronomer article, one originally written back in 2010 and that’s been consistently popular with our readers:  Will an astronaut explode if they take off their helmet? Our feature item introduces my new co-host, and … Continue reading →

Picking fights with a flat-earther

Urban Astronomer avatarPosted on 2 Jan, 2017 by Allen Versfeld21 Mar, 2017
Flat Earth Map

They tell us we’re living in a post-truth world, whatever that’s supposed to mean.  All I know is that there’s a growing number of people who look at the vast store of human knowledge, and reject it.  People who hear experts speak on science, politics, medicine, and say “Nope! I saw a YouTube about this, and I know better!”.  And there’s no starker demonstration of this than the modern flat-earther. How does this happen? What makes sane adults, with an education … Continue reading →
