What is about the study of the stars that captivates so many? Paul Fellows of the Cambridge Astronomical Association explains about his subject. Hear about dark matter, isotopes, space probes and the association's weekly events in Cambridge.
And that’s pretty much all from the Science Show on Cambridge 105 as the show takes a holiday. For news of what's next, follow us on twitter@105science.
You can still pick up all 60 of our podcasts at http://cambridge105.fm/podcasts/science-show/ or go to the iTunes Store and search for 105 science or Cambridge 105. Finally, many thanks to the dozens of guests who informed us how science takes shape in Cambridge, England today. Bye from me, Roger Frost.
