Solar Storms Are Noisy

April 4, 2012 · 0 comments

A doctoral student at the University of Michigan has created a sonic representation of the intense solar storm that erupted in early March. Robert Alexander gathered 90 hours of raw data from two NASA spacecraft–the MESSENGER and the Solar and Heliospheric Observatory. Through isomorphic mapping, he applied that data to an audio waveform. The resulting sound lasted only a fraction of a second, so Alexander used algorithms to extend the playback length. The final soundtrack portrays a cacophony of  solar particles emitted by the storm as they slammed into the spacecraft. Listen for yourself in the clip below.
