The mysterious vocals of Rosetta’s Comet – New Technology

There comes a mysterious signal from the comet as Rosetta’s lander sits on.
– This is brand new for us, says Karl-Heinz Glas Meier at Braunschweig University of Technology in Germany.

The comet 67P / Churyumov-Gerasimenko was joined by the lander Philea on Wednesday after years of planning. The lander bounced three times and stood on the edge, but ESA considers that the operation was a huge success and went as planned.

One thing they were not planned was that the comet 67P / Churyumov-Gerasimenko has started to “talk” and “sing,” writes ABC Science.

The ESA has picked up a mysterious signal that appears to come from the comet, which can be interpreted as – a song.

There are five instruments (Rosetta Plasma Consortium), which measures the plasma around the comet to increase understanding of the variations in the activity.

But when the researchers recorded signals with frequencies of 40-50 millihertz so they stumbled over a total surprise. 67P / Churyumov-Gerasimenko uttered sound.

– This is exciting because it is completely new to us. We were not expecting this and are still working on understanding the physics around what is happening, says Karl-Heinz Glas Meier at Braunschweig University of Technology in Germany to ABC Science.

Apparently it seems the comet’s weak magnetic fields oscillate up and down at low frequencies. For it to be audible to the human ear, so the researchers increased the frequency of 10,000 times.

The researchers’ theory is that the oscillations may arise from the ionization of neutral particles from the exhaust of gases.
