My favourite podcast is News Radio’s Star Stuff, hosted Stuart Gary. While I don’t really know my quarks from my dark matter, the technical segments (such as on gamma ray bursts, or GRBs for those in the know) are always very well explained from either Gary himself or any of his ‘go to’ experts. The program also spends a lot of time on the latest rocket launch from all round the world, whether it’s the first ever (very wealthy) tourist into space, Chinese tests, or American trips to the international space station. I find it endlessly fascinating and Gary’s enthusiasm makes for invigorating listening.
