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 →

Astronomers have identified the biggest star known to have exoplanets yet, upsetting standard planetary formation models. To date, b Centauri is the biggest star known to host an exoplanet. Estimates of its mass put it at between two and four times the previous record holder, meaning it could be up to ten times bigger than our own Sun.

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 →
