Once a month, I take a look at some of the latest news in astronomy as part of Pythagoras’ Trousers, a weekly science show broadcast on Radio Cardiff. The show’s main presenter is Rhys Phillips, a research engineer and musician who graduated from the School of Physics and Astronomy in 2008, but once a month he hands the microphone to me to discuss what’s been occurring in the world of astronomy.

This month I talk to Edward Gomez about a (not so) near miss by an asteroid, and an new insight into the inner workings of a supernova – the final explosion at the end of a massive star’s life. With National Astronomy Week almost upon us, I spoke to the Royal Astronomical Society‘s Robert Massey about what’s in store, and to our resident amateur observer Hugh Lang about what to expect in Cardiff and around Wales.

What’s available here is an extended version of the astronomy section of the show. You can listen to the full version of this week’s episode, and listen to past episodes, on the Pythagoras’ Trousers episode page.

Originally broadcast on Monday 24th February 2014, on Radio Cardiff 98.7FM.
