Set of tools installed on the Rosetta ESA, managed to get the mysterious "Melody" from the comet 67P / Churyumov-Gerasimenko.

It is believed that the sounds associated with the oscillations of the magnetic field near the comet. They were recorded by a set of five instruments Rosetta Plasma Consortium.

The human ear is not able to absorb the comet song, because it is in the range of 40 to 50 MHz, very far from the range of human perception, which is usually between 20 Hz and 50 kHz. To a man could distinguish sounds, scientists Rosetta project to increase the frequency of 10 000 times.

Tool Set Rosetta Plasma Consortium, established on the Rosetta orbiter, includes five tools that provide a wide range of data on ambient plasma environment of comet 67P.



Sounds coming from the comet was first detected well Rosetta magnetometer in August, when the unit close to a distance of 100 kilometers. Scientists believe that sounds occur because of the activity of the comet, possibly in the emission of neutral particles into space, where they become electrically charged (or ionized). However, the mechanism that is responsible for the appearance of oscillations remains a mystery.
