All the instruments in this piece are created from sounds that were broadcast in the Jodrell Bank podcast of August 2008 "The Sounds of Space".
That podcast is available at
jodcast.net/archive/200808Extra/ and is very well worth listening to.
In no particular order, the instruments are:-
Proton Whistlers
Jovian S-burst
Solar doppler images
Solar energetic particles from the HELIOS mission
Plus the fine Lancastrian burr of Dr Tim O'Brien.
