The magnetic waves measured by ESA's Cluster mission in the magnetic foreshock above Earth – the first region of our planet's magnetic environment that solar wind particles encounter – during a solar storm. The video contains a 'sonification' of the magnetic waves obtained by transforming the frequencies of these magnetic waves into audible signals. During the storm, the magnetic waves in the foreshock roughly double their frequency and become more complicated than during calm space weather conditions, resulting in audible sounds that are around an octave higher and much more variable.
