Creepy “Singing” Sound Has Been Recorded on Rosetta’s Comet
A creepy “singing” sound has been recorded on Comet 67P/Churyumov-Gerasimenko, the comet which the Rosetta satellite landed upon earlier this week.
The recording was made one day prior to Rosetta’s landing, utilizing Rosetta’s Plasma Consortium (RPC) to pick up variations in the magnetic field surrounding the comet. The variations were registered as being around 40 to 50 millihertz, which is 10,000 lower than what can be heard by human ears.
The scientists at ESA still don’t understand what exactly is causing this sound, with them stating that they “did not expect this” and that they are “working to understand the physics of what is happening.”
The Rosetta satellite carried the robot probe Phalae to the surface of the comet, a journey which took 10 years and extremely precise programming, with the satellite’s journey being conducted automatically rather than manually.
Listen to the “Singing Comet,” as it has been dubbed by the ESA, below:
