Van Allen Echoes - a musical journey in eight minutes from sun to earth

Random Page  /  Random Song


This piece was inspired by sounds which were created by atmospheric lightning discharges and their interaction with the Van Allen Radiation Belt. These sounds* have been detected and recorded by the University of Iowa (http://www-pw.physics.uiowa.edu). I further processed the sounds using the GRP A4 synthesizer and than augmented them with a 'spacy' piece of music. As always recorded live in one track and using the famous coat from Kazakhstan. Why does the piece last 8 minutes - it's the time particles need from sun to earth and reach the Van Allen Radiation Belt - we can see them as polar lights.
The video snippets are taken from the NASA homepage (www.nasa.gov).

*The Van Allen Probes EMFISIS Waves instruments detected these signals with two orthogonal magnetic antennas (Bv and Bu) during UTC hour 18 of September 11, 2012. The predominant feature is a barrage of whistlers which originate with lightning discharges on Earth. These signals propogate along magnetic field lines through the thin ionized gasses of space which allow the higher frequencies to travel faster than the lower frequencies. This results in a frequency dispersion and the characteristic whistling tone, which also sounds a little like science-fiction movie sound effects.
