The physicist Robert Kieffer and the musician Vincent Hänni have worked together on an acoustic performance that has what comes from the cosmos and passes through us without our knowledge as its primary source. Between physics and music, they thus offer a live electronic performance based on the use of detectors of particles (muons) as well as various electromagnetic sources (natural radio waves). We now know it was thanks to supernovae that atoms combined and new heavier elements were produced. A good reason for paying tribute to them by making audible what they send to us from so far.
