Incredible recording of the sound of ‘singing comet’ is unbelievable
THERE is no sound in space but it doesn’t mean that comets can’t sing and and this is the incredible PROOF.
Scientists have made a staggering discovery and recorded a mysterious ‘song’ coming from Comet 67P/Churyumov-Gerasimenko as they prepare to land tomorrow.
Rosetta astronomers are on the brink of a landmark mission as they attempt for the first time ever to launch a discovery probe – Philae – and land it onto the comet.
Meanwhile the Rosetta Plasma Consortium, which is part of the team, has uncovered the strange song using instruments that are designed to study unusual phenomena including the interaction of the comet with solar wind and the continuous stream of plasma emitted by the Sun.
Plasma is known as the fourth state of matter and is an electrically conductive gas that can carry magnetic fields and electrical currents and scientists have recorded the moment this occurs.
RPC scientists were taken by surprise when they heard the remarkable song first hand.

Karl-Heinz Glaßmeier, head of Space Physics and Space Sensorics at the University of Braunschweig, Germany said: “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.”
Glaßmeier said the ‘song’ is being emitted in the form of oscillations in the magnetic field in the comet’s environment.
The song, which is reminiscent of a cricket’s mating call or an Australian Digeridoo, is sung at 40-50 millihertz, far below the audible level for human hearing – which is around 20Hz.
To make the music audible to the human ear the frequencies have been increased by a factor of around 10,000.
Scientists believe the sound was created by the activity of the comet – as it releases neutral particles into space where they then become electrically charged.
The Philae lander will be leaving the Rosetta at 8.35am British time on Wednesday and it will take around seven hours for the probe to land on the comet if conditions remain steady.
