May 2007 Extra
This is the first of our new mid-month shows. First we get some breaking news from the Hubble Space Telescope, we listen to the second half of our interview with Carole Mundell about active galactic nuclei and supermassive black holes, and we put your questions to Tim in the Ask an Astronomer segment. For the extra shows we won't be having the normal format intros and outros but we still won't take them too seriously. As a start we work out how many rice crispies you could fit in the 76m diameter Lovell Telescope. Can you work it out?

Interview with Dr Carole Mundell (Liverpool John Moores University)
Nick Rattenbury talked to Carole Mundell about supermassive black holes in active galaxies. We find out that black holes aren't really great cosmic vacuum cleaners and allow some matter to escape their grasp and be hurled out in jets. Some of these jets even appear to be moving faster than light.

Ask an astronomer - Oscillations and Planets
Ian puts listener questions to Tim. First up we find out what the bright objects in the sky are. Next we find out how we can tell apart stars expanding and contracting from extrasolar planets.
