June 2008 Extra
In the show this time we find out how astronomers and particle physicists are detecting cosmic rays hitting our atmosphere with the Pierre Auger Observatory in Argentina [13:43 - 40:41]. Nick also gives us an update on some recent extrasolar planet discoveries which have found a planet only 3.3 times the mass of the Earth orbiting a star thought to be a brown dwarf [2:13 - 8:40].

Interview with Dr Tim Huege (Karlsruhe Institute of Technology)
Nick talks to Tim Huege about the Pierre Auger Cosmic Ray Observatory. The observatory covers a huge area on the Argentinian Pampas and watches for particle showers caused by high energy cosmic rays hitting the Earth's atmosphere. This gives us a chance to investigate particles with energies beyond those we can explore with man-made particle accelerators.
