Impossible exoplanets and Rhetoric

Posted on 12 Jan, 2022 by Allen Versfeld4 May, 2023

Socrates Address by Belgian artist Louis Joseph Lebrun 1867

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 topical – some astronomy news! Impossible exoplanet As covered previously on this website, the science media were very excited to report … Continue reading →

Posted on 10 Sep, 2020 by Allen Versfeld10 Sep, 2020

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 →

Southern skies and Northern skies

Posted on 10 Jul, 2020 by Allen Versfeld10 Jul, 2020

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 complete answer. Which brings us to this episode, in which I describe how there really isn’t a … Continue reading →
