Lockout Casualty Posted November 12, 2014 Share Posted November 12, 2014 http://rosetta.esa.int/ - Live stream from ESA Rosetta's comet sings a mysterious 'song' The Rosetta mission has detected a mysterious signal coming from Comet 67P/Churyumov-Gerasimenko. The mission has five instruments in the Rosetta Plasma Consortium (RPC) that measure the plasma environment surrounding the comet. Plasma is a charged gas and the RPC is tasked with understanding variations in the comet's activity, how 67P's jets of vapour and dust interacts with the solar wind and the dynamic structure of the comet's nucleus and coma. But when recording signals in the 40-50 millihertz frequency range, the RPC scientists stumbled on a surprise — the comet was singing, they report. Through some kind of interaction in the comet's environment, 67P's weak magnetic field seems to be oscillating at low frequencies. In an effort to better understand this unique 'song', mission scientists have increased the frequency 10,000 times to make it audible to the human ear. First detected in August as Rosetta approached the comet from 100 kilometres, this magnetic oscillation has continued. Rosetta scientists speculate that the oscillations may be driven by the ionisation of neutral particles from the comet's jets. As they are released into space, they collide with high-energy particles from interplanetary space and become ionised. Because it is electrically charged, the plasma then interacts with the cometary magnetic field, causing oscillations. But to draw any conclusions about this, further work is needed. (There's a SoundCloud insert here.) "This is exciting because it is completely new to us," says Karl-Heinz Glaßmeier, head of Space Physics and Space Sensorics at the Technische Universität Braunschweig, Germany. "We did not expect this and we are still working to understand the physics of what is happening." Rosetta is currently lining up to deploy its robotic Philae lander to the comet at 20.00 AEDT. During landing manoeuvers, the RPC is expected to help tracking Philae's descent to the comet's surface. The time between separation and landing is expected to take around seven hours. It takes 28 minutes and 20 seconds for signals to travel at the speed of light from Rosetta to mission control in Germany. http://www.abc.net.au/science/articles/2014/11/12/4126840.htm Someone should totally sample this sound. Some cool stuff. Link to comment Share on other sites More sharing options...
SabreFan1 Posted November 12, 2014 Share Posted November 12, 2014 The sound is pretty annoying. It's cool knowing that it's coming from a comet, but it's still irritating to listen to. Link to comment Share on other sites More sharing options...
avelanch Posted November 12, 2014 Share Posted November 12, 2014 i'm pretty sure it's already been sampled in a dub step song.... Link to comment Share on other sites More sharing options...
RUPERTKBD Posted November 12, 2014 Share Posted November 12, 2014 Even though I totally understand the concept, it's always hard for me not to assume that a comet is not necessarily travelling in the opposite direction of it's tail. It just seems counter intuitive to think that it's just as likely to be moving in the same direction, or at right angles to it's tail. Also, judging by the comet's name, I'm going to take a wild guess and say that it was discovered by Russians.... Link to comment Share on other sites More sharing options...

nucklehead Posted November 12, 2014 Share Posted November 12, 2014 No that this is the first time man has been on a comet. And I just realized the article says nothing abut that. I'm listening to the TV and talking back to it online. I'm obviously getting too old... Link to comment Share on other sites More sharing options...
Chalky Posted November 12, 2014 Share Posted November 12, 2014 I will sample it at my rehearsal on Friday, slow it down and make a beat. I am so F'N JACKED! on space right now. Today is a good day. Link to comment Share on other sites More sharing options...

Warhippy Posted November 12, 2014 Share Posted November 12, 2014 It's a good day to be a human, which lately has been a hard one to say convincingly. But sadly this momentous event is being over shadowed by Kim Kardashians ass in some magazine right now labeled "break the internet" One of the single most important dates in space exploration being hijacked by some vapid cretins posterior... Frigging tragic. That being said, I cannot wait for them to start deciphering the data from this, the amount of intricacies involved in just getting there were astronomical (no pun intended) from circling the earth 5 times to sling shotting around another planet to successfully dodging the debris trail to land and now drill. Amazing times Link to comment Share on other sites More sharing options...

Amazing times Haha, you should have put "no pun intended" up there instead. Why do people give these "celebrities" attention anyways? If everyone just ignores them, they will go away. In all seriousness though, very cool for science! (the comet thing) Link to comment Share on other sites More sharing options...

Amazing times But what a picture. That thing could block out the sun...in a good way In all seriousness, I have been listening to the sound of the magnetic field frequency on repeat for the last two hours. This is the coolest thing that I have seen in many many years, possibly my entire life. Link to comment Share on other sites More sharing options...

Captain Aerosex Posted November 12, 2014 Share Posted November 12, 2014 Wait what about KK's ass? Srsly tho that's amazing. How they managed to land on such a fast moving object is beyond me. Link to comment Share on other sites More sharing options...

How they managed to land on such a fast moving object is beyond me. once you are moving about the same pace it's not that hard. Getting the timing down so they can end up close to eachother after all that slingshotting is what impresses me. the actual landing part doesn't seem that hard.

I guess it's all in the preference. Nasa probably would have had an easier time landing on her butt than the comet though... Link to comment Share on other sites More sharing options...
