Most of the Space is an empty vacuum. But not all of it: somewhere, aggregations of matter define structures in the Universe, for example rotating around a black hole: a so-called accretion disk. The matter of this structure is a plasma, a state so hot that the atoms are divided into their ions and electrons. This plasma is in a turbulent regime.
Considering the intrinsic connection between plasma and magnetic fields, this turbulence leaves a sign, a sound generated by its motion, a voice nonaudible outside the system itself (as we know the sound does not propagate in the vacuum).
This video gives you this possibility, using real plasma data to recreate the sound that you are hearing. At the same time, the 3D visualization explores the mechanisms beyond the generation of the turbulence.
