Voyager Captures Sounds of Interstellar Space

NASA's Voyager 1 spacecraft captured these sounds of interstellar space. Voyager 1's plasma wave instrument detected the vibrations of dense interstellar plasma, or ionized gas, from October to November 2012 and April to May 2013.
The graphic shows the frequency of the waves, which indicate the density of the plasma. Colors indicate the intensity of the waves, or how "loud" they are. Red indicates the loudest waves and blue indicates the weakest.
The soundtrack reproduces the amplitude and frequency of the plasma waves as "heard" by Voyager 1. The waves detected by the instrument antennas can be simply amplified and played through a speaker. These frequencies are within the range heard by human ears.
Scientists noticed that each occurrence involved a rising tone. The dashed line indicates that the rising tones follow the same slope. This means a continuously increasing density.
When scientists extrapolated this line even further back in time (not shown), they deduced that Voyager 1 first encountered interstellar plasma in August 2012.
The Voyager spacecraft were built and continue to be operated by NASA's Jet Propulsion Laboratory, in Pasadena, Calif. Caltech manages JPL for NASA. The Voyager missions are a part of NASA's Heliophysics System Observatory, sponsored by the Heliophysics Division of the Science Mission Directorate at NASA Headquarters in Washington.

It might be that I suck at science but how can sound be detected in space, where there's a vacuum and no way that sound can physically be able to travel through?

[@Bukunox]

It's described in the first ten seconds. Yes you're right, sound can't be transmitted in the vacuum of space, but this isn't a normal microphone installed on voyager. Apparently they have a device that measures the vibrations of ionized gas it captures, and then as you said, it translates that into a sound frequency

[@discountconsulting]

Why is the ascent of the pitch/density the same for both clouds? Does it have something to do with the speed of the probe and the viscosity of the cloud as it gets penetrated and displaced? I wonder why these little clouds don't dissipate completely in deep space. You would expect gas within a vacuum to disperse to maximum sparsity, no? Does charge attraction somehow contain the inertia of the particles to prevent them from dispersing?

[@ohhmanitscam]

I guess gravity could potentially help them stay near eachother, other than that I have no clue..

[@discountconsulting]

I don't know how strong charge attraction is once atoms are ionized into a plasma within a relatively cold vacuum. Maybe the protons and electrons condense somewhat without collapsing into de-ionized atoms/molecules for some reason. Are these plasma clouds condensing progressively hence the rising pitch as Voyager goes through them? That seems logical since atmospheric clouds are also sparser near the edges and denser in the center. But why does the pitch-rise occur at the same rate? This seems like it would occur due to Voyager's speed and not just by coincidence of the plasma density increasing at the same rate for both clouds. Maybe the detector oscillation speed just increases at this rate regardless of what is causing it to vibrate. It might help to know how the microphone/detector works.

[@discountconsulting]

***** That's a good point. I keep picturing them similar to very high altitude clouds, though water vapor in the atmosphere, even at high altitudes, has atmospheric gases to disperse into and thus form a density gradient. Maybe, however, density variation could be caused by compounding of the electrostatic forces between the plasma particles as you get further into the cloud? Presumably if the cloud is contained within the attractive forces of its own charge (and gravity), the energy within it is insulated from escaping. As such, you might expect the particles on the exterior of the cloud to stretch further from each other than those more in the middle. Also, I wouldn't be too quick to assume these clouds are bounded by total vacuum. Even that deep into space, I would expect their to be charged plasma, only very sparse. As far as I know, electrons and other charge fields don't have any boundary so the farther they get from each other, the more they expand to fill up whatever gaps would form between them if they didn't. Even if these clouds are surrounded by very sparse plasma, though, I think that plasma would have to contain a significant amount of warmth to cause these clouds to disperse, so they are probably just hanging together under their own charge and gravity and dispersing a bit at the edges due to their own internal warmth. Idk, though, could any warmth within them radiate away as electromagnetic radiation and cause the edges to contract in toward the rest of the cloud leaving no density variation? If so, why the pitch variation? If you think I'm completely misguided in how I'm thinking about this, please explain how you see it.

[@discountconsulting]

Angela Tegge Good points, but can ionized plasma particles even exhibit polar attraction considering that they are stripped of all electrons? If the attraction is gravitational, how voluminous and/or massive/dense must these clouds be to have significant gravitational compression? Also, why doesn't the pitch rise and then fall as the probe exits out the other side of the cloud? If the cloud had a uniform density-gradient on all sides, wouldn't you expect the pitch to 'wind down' in the same way it 'wound up?' Or could it be that the probe is going so fast that it totally blasts away whatever is left of the cloud in front of it by the time the pitch reaches maximum frequency? Anyway, I wish I knew more about how ionized plasma behaves based only on the charge interactions between (ionized) particles. It seems like there should be interspersing of electrons with the positively charged particles but what happens to polarity caused by the assymetry of nuclei if electrons are stripped and buzzing around outside their nuclei?

[@discountconsulting]

Angela Tegge Maybe I'm assuming too much that it's ionized plasma. If it's not, I see your point about the type of gas and temperature. I share your general belief that there is always some charge polarity at work just by virtue of the particles in question being charged and thus not neutral. Still, I would not know how to factor gravity in or even how to estimate the size of the clouds, except maybe by knowing the probe's speed and the duration of the sounds. Do you have a web link regarding the way the detector works? I would like to know more about the way plasma emits EM radiation. I've always read that an electron has to drop into an orbital to emit a photon, though it seems logical that free electrons could do so as well in situations where they are accelerating toward a positive charge and then re-stabilizing.

Vibrations is a perturbation(pressure perturbation) with some frequency. It happens that the human hear interprets some frequencies as sounds.The velocity in which vibrations progragate is sound velocity ( but is has nothing to do with "sound"). Sound velocity is a property of the fluid meaning that velocity propagation will be different depending on the properties of the fluid. So, light and pressure (or sound) progragation are different phenomena.

[@rayandreina]

I remember reading in the newspapers about Voyager 1's Encounter with Jupiter: the Great Red Spot being an immense, cyclonic storm, three times the size of Earth; Jupiter possessing a surprise ring system; and the erupting volcanoes of Io -- just as though it was yesterday (early March, 1979) -- I would graduate from high school that term.

Space isn't actually "empty". It's basically the closest thing to a vacuum we know of but there is still bits of matter floating around that can transmit things like sound. Think of a star, reactions take place to create light and it's sent far out into space. In these reactions it also creates and throws out particles of matter. This (among other things) allows sound to travel through an apparently "empty" space. Also, think of light as packets of energy. We can't touch them. Hope that helped

[@randall.chamberlain]

Jess, you miss an important fact. We cannot hear radio waves. We use sound waves we can hear to modulate (shape) the radio waves either in amplitude (AM) or in frequency (FM). We do this because radio waves can travel much faster (light speed), fade much more slower and are more reliably than sound waves. In the radio itself, we de-modulate (recover) the original pattern from the sound waves and then amplify it so that we can hear it by using a vibrating device (speaker)

[@Stealthmuiz]

why do people think this is what you actually would hear in space? You wouldn't hear anything at all. This is just the sound of the vibrations of the spacecraft that are then digital amplified to something we can hear.

[@diddlydevil2846]

Technically light is not "physical" since it has no mass so it's not necessarily filling any space, but that's besides the point. "Vibrations" (in this case, they're called frequencies) in light is what makes color rather than sound. So no, sound cannot travel through light, at least in any way I know of. If you read the intro of the video, you'll see the sounds the satellite picked up were the vibrations of ionized gas floating through space. Hope this helped :)
