Comet 67P/Churyumov-Gerasimenko Sounds Like Inuit Throat Singing: Listen To Rosetta
THE Rosetta spacecraft’s Philae lander has picked up sound on Comet 67P/Churyumov-Gerasimenko, upon which it now sits.
The ESA released tbgis audio clip of 67P/C-G singing. MNany sya it sounds a lot like Predator, the bearded Hollywood alien that tried to kill Arnold Schwarzenegger.
The sound is made by Rosetta’s Plasma Consortium (RPC) detecting variations in the magnetic field around the comet, “due to interactions between 67P/C-G’s coma and the plasma from the Sun, better known as solar wind. These variations resulted in frequencies between 40 to 50 millihertz, about 10,000 times lower than can be detected by humans. ESA scientists altered the frequency of the comet’s song into human hearing range, and discovered it was a series of clicks that are very reminiscent of Predator’s growl.
“This is exciting because it is completely new to us. We did not expect this and we are still working to understand the physics of what is happening,” RPC principal investigator Karl-Heinz Glaßmeier said in a press release.
It sounds a bit like Predator. But it sonds more like Inuit Throat singing:
