Comet 67P Sings a Mysterious Song caught by Rosetta Spacecraft

Comet 67P is said to be 'singing' as the Rosetta Spacecraft hovers around it. It is believed to be the result of oscillations in the comet environment's magnetic field, a phenomenon that can be translated into a kind of song, which, by the way, are inaudible to the human ears.  The ESA has 'amplified' its sound by increasing the frequencies to make it audible for us humans on Earth.

Rosetta's magnetometer experiment first picked up the song when it closed in on the comet back in August. "The scientists think it must be produced in some way by the activity of the comet, as it releases neutral particles into space where they become electrically charged due to a process called ionisation. But the precise physical mechanism behind the oscillations remains a mystery,"  the ESA said.

If you really want to freak yourself out, they say compare the comet soundtrack to the clicking sounds Predator makes. (See 2nd vid)
