Something strange is happening on comet Churyumov-Gerasimenko 67P as space engineers prepare for a historic landing: the icy space rock is 'singing'.

The mysterious sound has baffled scientists, who recorded it using a Rosetta instrument originally designed to analyse the comet's magnetic field.

Instead, this instrument picked up a strange bubbling sound which scientists believe was created by a stream of electrically-charged particles.

'This is exciting because it is completely new to us,' said Karl-Heinz Glaßmeier, principal investigator with Rosetta's Plasma Consortium.

'We did not expect this and we are still working to understand the physics of what is happening.'

Just kidding.

Pythagoras knew this already 2500 years ago.

“In a theory known as the Harmony of the Spheres, Pythagoras proposed that the Sun, Moon and planets all emit their own unique hum (orbital resonance) based on their orbital revolution,” wiki

We knew about Frehley’s Comet singing thirty years ago.

Looking forward to watching the landing tomorrow.

Hope they pull it off, it sounds tricky.

Obama’s home planet was a comet

I suppose this may be close to a modern description of this “sound” originating in the gaseous emanations of the comet interacting with solar radiation and the solar wind.

Great, another reality show.

Comet, it’ll make your teeth turn green
Comet, it tastes like gasoline
Comet, it’ll make you vomit
So get some Comet, and vomit, today.

A well a don't you know about the bird?
Well, everybody knows that the bird is the word!
A well a bird, bird, bird, well the bird is the word
A well a bird, bird, b-bird's the word
A well a bird, bird, bird, b-bird's the word
A well a bird, bird, bird, well the bird is the word...

Don’t forget Bill Haley’s Comet some 20 years before that.

:) — Yeah, I’m not sure he was wrong.

Again the orthodox gravitational cosmologists and astronomers are "Surprised" and "shocked" when the learned that Churyumov-Gerasimenko 67P has been found to be "singing" in the magnetic spectrum in Rosetta's instruments. . . Of course, the Electric Universe Cosmologists and Astronomers are not surprised or shocked at all as the comet is vibrating as it electrically machines its surface and releases electrons, OH iONs, and adjusts its charge as it moves closer and closer to the solar cathode. . . . So, another Electric Universe PING!

I am detecting that, of late, scientists have combined the theories of amazement, surprise, and astonishment into the more widely accepted theory of bafflement.

I am detecting that, of late, scientists have combined the theories of amazement, surprise, and astonishment into the more widely accepted theory of bafflement.

They are experiencing "bafflement" because they have hitched their cosmological wagon to the the weak gravitic theory of the Universe instead of recognizing that the electromagnetic force is also infinite in reach, but is 39 orders of magnitude stronger than gravity, . . and every where we look in the Universe we see evidence of electro magnetic forces at work. EM force is also scalable from the microcosm to the macrocosmic. . . and the phenomena we see out in the Universe can be duplicated in the laboratory in the microcosm. The theories of the Electric Universe are entirely explicable without having to invoke magical forces such as "dark energy," or magical substances such as "dark matter," to make the theories work.

How about “Comet Living”
No - no - wait - “Comet Dwellers”
Wait wait wait... “Comet Survivor”
No yeah I got it - “The Comet Games”!!

invoke magical forces such as "dark energy," or magical substances such as "dark matter," to make the theories work.

I think so far, everything on the detection of dark matter and dark energy have been a "swing and a miss".

They're in a bind coming up with provable fudge factors :)

And now that we can land a spacecraft on a comet....

Hey!

Time for a return ticket?

The Rosetta comet is singing: as the orbiter approaches, the ESA uploads audio of the comet's warbling, magnetic 'song' — The Independent UK.

The 'song' - thought to be caused by oscillations in the comet's electrically charged pseudo-atmosphere - is well below the threshold of human hearing

JAMES VINCENT — Tuesday 11 November 2014

As the Rosetta orbiter nears the comet Churyumov-Gerasimenko 67P and prepares to fire the Philae lander at its surface, scientists from the European Space Agency (ESA) have been puzzled by an unexpected phenomenon: the comet is ‘singing’.

Instruments designed to analyse the plasma environment surrounding 67P have recorded a low, bubbling song (listen below) though to be created by a stream of electrically charged particles released as the comet hurtles through space at 34,175mph.

“This is exciting because it is completely new to us,” said Karl-Heinz Glaßmeier, principal investigator with Rosetta’s Plasma Consortium (RPC) in a press statement. “We did not expect this and we are still working to understand the physics of what is happening.”

Glaßmeier and his team have uploaded the comet’s song online, increasing the pitch 1,000 times as the original audio was well below the threshold of human hearing, playing out among the stars at between 40 and 50 millihertz (humans can hear sounds starting at around 20 hertz up to 20 kilohertz).

The instrument that has picked up the warbling audio is Rosetta’s magnetometer, designed to detect the strength of magnetic fields. Like all comets, 67P has magnetic pseudo-atmosphere known as a ‘coma’ - activated as the 4km long chunk of ice draws closer to the Sun and solar winds whip up electrically charge particles of gas and dust.

Although the exact mechanism behind this audio is unknown, ESA scientists say it might prove useful all the same, helping to guide the descent of the Philae lander as it undertakes its delicate and historic mission to the comet’s surface tomorrow afternoon. Who knows, in the circumstances it might even prove to be a song of welcome.
