You don't need to know anything about astronomy to enjoy The Sky at Night. Patrick Moore, his co-presenters and guests make sure that whatever topics they are discussing, whether meteoroids or supernovae, dark matter or Moonquakes, all are explained so that casual viewers can have some level of understanding. Educational and accessible, you would have thought the BBC would promote the programme and build on the way it is not afraid to discuss challenging theories and ideas about the stars, the nature of matter, the universe and lots more (pardon the pun). Sadly TSAN appears is being gradually pushed more and more to the margins of BBC output, shifted to BBC World or BBC4, almost no promotion, and with no crossover where it could be most valuable in an educational role, between TSAN and children's programmes. Just like the stars in the heavens, it takes a little bit of time and effort to find TSAN - but it is very much worth your while. Do it while you can!
