The 'singing comet' 67P/Churyumov-Gerasimenko
Rosetta's Plasma Consortium (RPC) has uncovered a mysterious 'song' that Comet 67P/Churyumov-Gerasimenko is singing into space. The comet seems to be emitting a 'song' in the form of oscillations in the magnetic field in the comet's environment. It is being sung at 40-50 millihertz, far below human hearing, which typically picks up sound between 20 Hz and 20 kHz. To make the music audible to the human ear, the frequencies have been increased by a factor of about 10 000. The resulting recording can be downloaded here.
