Comet's Eerie 'Song' Captured by Rosetta Spacecraft

Scientists have picked up on the mysterious "song" of a comet speeding through deep space. European Space Agency officials have used their Rosetta spacecraft to listen to a sound emitted by Comet 67P/Churyumov-Gerasimenko. The comet song capture by Rosetta is produced by "oscillations in the magnetic field in the comet's environment," ESA officials said in a statement. The Rosetta spacecraft was able to pick up the strange, echoed clopping sound, but if a human were floating through space next to the comet, he or she wouldn't hear anything at all. Comet 67P/C-G is singing well below the frequency that the human ear can hear, according to ESA. The frequency of the sound was increased by a factor of approximately 10,000 for an audible rendering of the comet's tune. More via Space.com.
