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 http://www.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 Tim O'Brian.

All instruments were created in Kontakt, hosted in Logic Studio and driven by noatikl.

Video imagery is from "Our Mr Sun" (1956), directed by Frank Capra - the first film in the Bell Systems Science series. (less info)
