El orbitador Rosetta en estos momentos está atravesando momentos difíciles...
Pero dentro de las "curiosidades" (no obstante esas dificultades la cantidad de información que se está recabando es inmensa) se encuentra una que además de ponernos los pelos de punta nos deja con más interrogantes...
El audio está maximizado a una frecuencia superior para que el oído humano pueda escucharlo.
Y la pregunta no es la transmisión del sonido a través del espacio. En el espacio NO hay atmosfera que permita la conducción del sonido. La ionización juega un papel importante es esta situación.
But one observation has taken the RPC scientists somewhat by surprise. The comet seems to be emitting a ‘song’ in the form of oscillations in the magnetic field in the comet’s environment. It is being sung at 40-50 millihertz, far below human hearing, which typically picks up sound between 20 Hz and 20 kHz. To make the music audible to the human ear, the frequencies have been increased by a factor of about 10,000.
The music was heard clearly by the magnetometer experiment (RPC-Mag) for the first time in August, when Rosetta drew to within 100 km of 67P/C-G. The scientists think it must be produced in some way by the activity of the comet, as it releases neutral particles into space where they become electrically charged due to a process called ionisation. But the precise physical mechanism behind the oscillations remains a mystery.
“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,” says Karl-Heinz.
