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].
