Voyager Captures Sounds of Interstellar Space

NASA Jet Propulsion Laboratory
Published on Sep 6, 2013

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.

Seriously… we live in marvelous times.

Why not ban war and explore the hell out of everything?

We’re waiting…

Sometimes life feels like this:

At other times it almost feels “like it’s supposed to…”

ok here is the scoop…

I recorded some yammerings in audio.

Didn’t get all that far but got a good start…


Will need to cut into pieces as the files were way over the limits for upload here, which is 100MB. The main one is 384MB for about 15 minutes of Igular utterances. Soon… soon… tomorrow eve probably.

Note: I will stick them on here where they are supposed to be.


OK, fair warning… these are 100% unedited and will no doubt be borderline excruciatingly awful to listen to. But That is, in essence, what an Ig is. Learn why I only half a handful of friends. Learn why even uncontacted tribes in remote forests want me dead.





Well, there’s 15 minutes of not a lot. I will get the hang of it eventually, I would imagine.




I could not stop watching this. It just ended. Whoa. As a sorta soundman, this is deep passion that just sucked me right in. And I do not regret it. The first sound recording of the air moving, i.e. live, microphonic, of an unknown cornetist blowin for the phonautogram in 1857 (1857!) which was followed three years later by the human voice via a young lady singing Eu Claire de la Lune in 1860.

I was smitten.

You might, I did a little at first, think


FIRST SOUNDS: Humanity’s First Recordings of Its Own Voice


Edouard-Leon Scott de Martinville was the first person to record his voice and send it into the future. David Giovannoni recounts how First Sounds discovered and played back these recordings 150 years later.

The vid covers the timeline of their quest to bring to life the unplayable recordings that were made in the decade before Thomas Edison did his thing.

These gentlemen had to hear these sounds. And they not only succeeded, they made history in making history sing.

I warn you, though … it is compelling and it is 55 minutes. At least it was compelling to me!


New Horizons’ Best View of Pluto’s Craters, Mountains and Icy Plains Video
Published on Dec 4, 2015
This movie is composed of the sharpest views of Pluto that NASA’s New Horizons spacecraft obtained during its flyby on July 14, 2015. The pictures are part of a sequence taken near New Horizons’ closest approach to Pluto, with resolutions of about 250-280 feet (77-85 meters) per pixel – revealing features smaller than half a city block on Pluto’s diverse surface. The images include a wide variety of cratered, mountainous and glacial terrains – giving scientists and the public alike a super-high resolution view of Pluto’s complexity.


BRAVO to everyone involved in making the ability for this vid to exist a reality. See now, THAT’S Rocket Science! Really, thank you.

Nerds are awesome. Boffins, too. Ja, mon!

‘K, sorry, I’m ok now. Anyway, I stand firmly by my considered assertion that the farther out you go the weirder it gets.

And that suits me just fine.

Here is the photo featured in the video. It is stunning. Oddly, looking at it actually brought out the Fortean curmudgeon in me, bringing a smile closely related to one of my pet peeves.


Nice huh?

Over at ATS, where I am terminally logged in, member gortex said

This stunning picture was released today showing Pluto’s icy crust and the Sputnik Planum’s flats in unprecedented detail , not bad for something 4.67 billion miles away.

That made me think of all those wide-eyed folks who ceaselessly complain of the notorious NASA “low-res” cameras. It’s especially common regarding Mars pictures. Well, there are a lot more of them available. Anyway, I see it a lot and it eally makes me wonder. About people.

Look at the detail there even just above this line at the bottom of the picture. It isn’t enhanced, it just is.

851575_126361970881933_2050936102_nI think the resolution is phenomenal.

The rover cameras as well, are nice, especially the new guy. Some of those hills are quite far away.

I was seriously impressed with the main Curiosity camera and son, it takes a lot to do that. I am jaded to the max. Been looking a lot over the years. These rovers have indeed found some fascinating things. For some reason the media only cover the paredolia-based items. Some of whichare pretty entertaining.

Since I am a bit ranty now for some reason, my biggest peee is that there are never any microphones on rovers. Not just ours, either, Vlad. Seriously. It has an atmosphere. Not a lot of one, but there is one. So—there’s sound.

Let’s hear it, yo!

Even at retail prices it’d be what, a few thou? For off-the-shelf existing science-grade pro audio pieces. American, even. Madonne.

Ah, well, on this imagery, it is good for me even just to think that, “Heck, we can really DO that!”

Okay, thanks for reading.

Zimoun : Sound Sculptures & Installations | Compilation Video V2.2 from ZIMOUN VIDEO ARCHIVE on Vimeo.

Found this posted by a student on my recording engineering professor’s Facebook page. We are all most impressed.

Naturally, would very much like to experience one in person. Bravo Zimoun!
