Yesterday the clever bods at the European Space Agency landed their Philae space probe on a comet – and now that the probe has settled into its new home it has recorded the comet singing.
At the moment scientists don’t know why the comet is singing but they got a fairly good idea, they have theorised that the sound is due to the comet releasing neutral particles into space and they’re colliding with high-energy particles and that’s apparently what’s making the sound.
“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,” Karl-Heinz Glaßmeier, head of Space Physics and Space Sensorics at the Technische Universität Braunschweig, Germany, explained on the RESA Rosetta blog.
Apparently the song is inaudible to the human ear and had to be boosted ten thousand times before we can pick it up. The ESA has boosted the sound and uploaded the resulting eerie drone to Soundcloud for you to listen.
