ESA scientists detect eerie music emanating from Rosetta's Comet 67P

Most of us would never consider comets as being especially musically inclined, but ESA scientists preparing for tomorrow's historic landing on Comet 67P/Churyumov-Gerasimenko have discovered a strange series of sub-human-hearing oscillations amid particles in its magnetic field.  This "cosmic song" is created by micro-particles discharged by the comet that become electrically charged through ionization in a mysterious process not completely understood.  These lyrical magnetic oscillations are sung at the 40-50 millihertz range, far below human hearing.   Rosetta's Plasma Consortium team was unexpectedly surprised by the phenomenon and is working to unravel the mysterious physics behind this heavenly hit.  

Have a listen to the comet recording, its frequency amplified by 10,000 to permit our ears to enjoy.
