  • Excellent and uplifting

    I listen to a lot of news and climate podcasts, which can be a bit sad. This is an excellent podcast that catalogues some of the awesome stuff that comes with living in this era. And Sarah has done a great job carrying on from Mat!

  • Great content 👎 audio quality

    I love the content of this show but the audio quality is not up to scratch compared to the other podcasts I listen to. I end up listening to 5-10 mins and getting fed up with the bad audio so stop listening. Such a shame

  • Here we are now…

    This show used to have personality and was entertaining to a dummy like me; in turn I learned some and gained an interest in space. Now it sounds like an AI generated fact fest for the PhD holding choir. Borrrring.🙋🏻‍♂️

    Great to hear our great friend Mat again. Sarah does very well but nothing beats the comradery and exchanges between Mat and Bruce. (June '23)
