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 calm space weather conditions. The video contains a 'sonification' of the magnetic waves in the undisturbed foreshock, obtained by transforming the frequencies of these magnetic waves into audible signals. In the undisturbed foreshock, the sounds are very low pitch and monotonous.
