Comet 67P/C-G sings us an alien song – and it freaks Reeko out
While the Philae probe naps on the surface of Comet 67P/ Churyumov-Gerasimenko, scientists found that the comet is singing a lullaby to the sleepy little probe – albeit not quite the sweet soothing melody your mother sings.
Rosetta, the orbiter flying around Comet 67P/ Churyumov-Gerasimenko while Philae sleeps, measured the magnetic field around the comet and found that oscillations in the magnetic field are being emitted at around 40-50 millihertz, too low for humans to hear with their ears (human hearing ranges between 20 Hz and 20 kHz). But a German composer, curious about what the comet was singing to us, increased the frequency of the oscillations about 100 times to produce sound waves in the range that humans can hear.
Scientists are not yet sure how the comet is producing the oscillations, which to Reeko, sound like creepy, chattering alien teeth.
