ESA’s Cluster mission has recorded the magnetic waves generated in the magnetic foreshock above Earth – the first region of our planet’s magnetic environment that solar wind particles encounter – during calm space weather conditions. This audio file contains a 'sonification' of the data, where sounds were obtained by transforming the frequencies of these magnetic waves into audible signals.
