You can tell they both love the subject so much and the guests they have are similarly thrilled to learn more about our universe.

Apple Podcasts5Russell0614United Statesa month ago - Entertaining and educational.
A very entertaining friendly conversation of astronomy topics. No one talked over each other and it easy to listen to.
Apple Podcasts5TacllemUnited Statesa month ago - Is this pitched at children?
Over excitable giggling presenters and GCSE level explanations make what should be a flagship show for the RSA into something more puerile. A real shame. Could be so much more.
